Multi-Display Gaming Artifacts Shown With AMD, 4K Affected Too

Vigile Re:The first step is admitting their is a problem (148 comments)

As far as I know no other article anywhere has published what problems actually exist with Eyefinity, as they are very different than the problems that exist with CrossFire on single display configurations.

Multi-Display Gaming Artifacts Shown With AMD, 4K Affected Too

Vigile Re:Seems like a bullshit article. (148 comments)

Maybe if you read the story, you'll find the "driver" and "version" are mentioned for both AMD and NVIDIA setups.

This is not a "bug" bug a substantial issue with advertised features.

NVIDIA GeForce GTX 780 Offers 2,304 Cores For $650

Vigile Re:Still slower than AMD (160 comments)

In GPU terms, yes. The shaders and cores are very different between AMD and NVIDIA (that's why AMD can have 1536 and compete with a HD 7970 with 2048 shaders).

Taking a Hard Look At SSD Write Endurance

Vigile Accuracy of math in question (267 comments)

It may be too late for this post, but Allyn over at pcper.com posted up some analysis of this article and that it leaves out important data:

Max data write speed did not take into account 8/10 encoding, meaning 6Gb/sec = 600MB/sec, not 750MB/sec.
The flash *page* size (8KB) and block sizes (2MB) chosen more closely resemble that of MLC parts (not SLC – see below for why this is important).
The paper makes no reference to Write Amplification.

"Write Amplification would be a factor of 500, meaning the flash memory is cycled at 500x the rate calculated in the paper." Gulp.

NVIDIA's New Flagship GeForce GTX 580 Tested

Vigile Re:Good write ups, good card (149 comments)

"just fine" differs from person to person. No, GTX 580s aren't required to play PC games and most of the time the lower cost GTX 460/HD 6850s are fine. But sometimes more power is just better.

SHIELD Tablet $299 Android Gaming Tablet Reviewed

Vigile Vigile writes  |  2 days ago

Vigile (99919) writes "Last week NVIDIA announced the SHIELD Tablet and SHIELD Controller but reviews are finally hitting of the devices this morning. Based on the high performance Tegra K1 SoC that integrates 192 Kepler architecture CUDA cores, benchmarks reveal that that the SHIELD Tablet is basically unmatched by any other mobile device on the market when it comes to graphics performance — it is more than 2.5x the performance of the Apple A7 in some instances. With that power NVIDIA is able to showcase full OpenGL versions of games like Portal and Half-Life 2 running at 1080p locally on the 19x12 display or output to a TV in a "console mode." PC Perspective has impressions of that experience as well as using the NVIDIA Game Stream technology to play your PC games on the SHIELD Tablet and controller. To go even further down the rabbit hole, you can stream your PC games from your desktop to your tablet, output them to the TV in console mode, stream your game play to Twitch from the tablet while overlaying your image through the front facing camera AND record your sessions locally via ShadowPlay and using the Wi-Fi Direct powered controller to send and receive audio. It is incredibly impressive hardware but the question remains as to whether or not there is, or will be, a market for Android based gaming devices, even those with the power and performance that NVIDIA has built."

Samsung release first SSD with 3D NAND

Vigile Vigile writes  |  about a month ago

Vigile (99919) writes "As SSD controllers continue to evolve, so does the world of flash memory. With the release of the Samsung 850 Pro SSD announced today, Samsung is the first company to introduce 3D NAND technology to the consumer. By using 30nm process technology that might seem dated in some applications, Samsung has been reliably able to stack lithography and essentially "tunnel holes" in the silicon while coating the inside with the material necessary to hold a charge. The VNAND being used with the Samsung 850 Pro is now 32 layers deep, and though it lowers the total capacity per die, it allows Samsung to lower manufacturer costs with more usable die per wafer. This results in more sustainable and reliable performance as well as a longer life span, allowing Samsung to offer a 10 year warranty on the new drives. PC Perspective has a full review with performance results and usage over time that shows Samsung's innovation is leading the pack."

$3000 GeForce GTX TITAN Z Tested, Less Perf than $1500 R9 295X2

Vigile Vigile writes  |  about 1 month ago

Vigile (99919) writes "NVIDIA announced its latest dual-GPU flagship card, the GeForce GTX Titan Z, at the GPU Technology Conference in late March with a staggering price point of $2999. Since that time, AMD announced and released the Radeon R9 295X2, its own dual-GPU card with a price tag of $1499. PC Perspective finally put the GTX Titan Z to the test and found that from a PC gamers view, the card is way overpriced for the performance it offers. At both 2560x1440 and 3840x2160 (4K) the R9 295X2 offered higher and more consistent frame rates sometimes by as much as 30%. The AMD card also only takes up two slots (though it does have a water cooling radiator to worry about) while the NVIDIA GTX Titan Z is a three-slot design. The Titan Z is quieter and uses much less power, but gamers considering a $1500 or $3000 graphics card selection are likely not overly concerned with power efficiency."

Intel Core i7-4790K Devil's Canyon Increases Clocks by 500 MHz, Lowers Temps

Vigile Vigile writes  |  about 2 months ago

Vigile (99919) writes "Since the introduction of Intel's Ivy Bridge processors there was a subset of users that complained about the company's change of thermal interface material between the die and the heat spreader. With the release of the Core i7-4790K, Intel is moving to a polymer thermal interface material that claims to improve cooling on the Haswell architecture, along with the help of some added capacitors on the back of the CPU. Code named Devil's Canyon, this processor boosts stock clocks by 500 MHz over the i7-4770K all for the same price ($339) and lowers load temperatures as well. Unfortunately, in this first review at PC Perspective, overclocking doesn't appear to be improved much."

New Intel SSD 730 Is Overclocked. Yes, Overclocked.

Vigile Vigile writes  |  about 5 months ago

Vigile (99919) writes "When Intel jumped on to the scene of the SSD market with the X25 series, they made a lot of waves with a custom built controller and performance levels not seen previously. In recent years, Intel has turned away from custom controllers and used third party ones from SandForce. This permitted easy product line management but took away the differentiation of the Intel SSD line. Today's release of the Intel SSD 730 returns Intel to the role of controller designer for consumer hardware. Taking the same 6 Gbps controller found on the Intel DC S3500 and overclocking it, running the bus at 100 MHz rather than 83 MHz, results in improved performance but not faster transfer speeds than many other, less expensive SSDs on the market. Intel's controller shows its strength in IOps testing. The overclocked state of this SSD also means more power and heat — PC Perspective read surface temperatures of 122F on their test unit."

NVIDIA Launches GTX 750 Ti with New Maxwell Architecture

Vigile Vigile writes  |  about 5 months ago

Vigile (99919) writes "NVIDIA is launching the GeForce GTX 750 Ti today which would normally just be a passing mention for a new $150 mainstream graphics card. But the fact that the company is using this as the starting point for its Maxwell architecture is actually pretty interesting. With a new GPU design that reorganizes the compute structure into smaller blocks, Maxwell is able to provide 66% more CUDA cores with a die size that is just 25% bigger than the previous generation all while continuing to use the same 28nm process technology we have today. Power and area efficiency were the target design points for Maxwell as it will eventually be integrated into NVIDIA's Tegra line too. As a result the GeForce GTX 750 Ti is able to outperform AMD's Radeon R7 260X by 5-10% while using 35 watts less power at the same time."

New WD Black2 Dual Drive Combines Full SSD and HDD in Same 2.5-in Package

Vigile Vigile writes  |  about 8 months ago

Vigile (99919) writes "Hybrid drives are not new to the computing world as the benefits of a hard drive with a large(-ish) NAND cache are well known. But desktop users will likely agree that having a full capacity SSD as a primary drive with a secondary, spindle based hard drive for mass storage is the most popular solution. For many notebook users that simply isn't an option as space is limited in most laptop chassis but today's brand new Dual Drive, the Black2 from Western Digital, mixes things up. In a single 2.5-in hard drive form factor, WD has packed a 120GB SSD in addition to a 1TB hard drive that share a single SATA connection and that can be installed in systems with a single drive bay. This isn't a hybrid, Windows sees two different partitions. There are some interesting software quirks and the SSD performance is middle of the road based on PC Perspective's testing, but the Black2 performs well enough in both SSD and HDD testing to get their full recommendation."

NVIDIA Brings Own Tablet to Market, Tegra Note 7

Vigile Vigile writes  |  about 9 months ago

Vigile (99919) writes "What do you do when you can't find many partners willing to put the work into your product that you think it deserves? Well if you are NVIDIA, you build your own and sell it. The first product that is part of NVIDIA's Tegra Note platform is being released, a 7-in form factor stock Android tablet called the Tegra Note 7. Based on the Tegra 4 SoC with its 4+1 Cortex-A15 CPU and 72-core GPU design, the Note 7 is among the fastest small tablets on the market and also includes features like DirectStylus support, front facing speakers and a $199 price tag. It does lag behind the Nexus 7 in battery life and screen resolution, but otherwise in PC Perspective's testing the Tegra Note 7 is able to compete in a crowded market quite strongly."

NVIDIA Releases Full GK110 GPU, GTX 780 Ti for $699

Vigile Vigile writes  |  about 9 months ago

Vigile (99919) writes "The battle over the discrete graphics card space continues to stay heated. AMD started releasing its new set of graphics cards, culminated with the R9 290X Hawaii flagship just before Halloween. That left a large performance and pricing gap between the $499 GeForce GTX 780 and the $999 GTX TITAN (that was clearly overpriced for gaming). Today's release of the NVIDIA GeForce GTX 780 Ti starts with a $699 price tag and offers performance that is 10-15% higher than the AMD 290X at 2560x1440 and 4K resolutions. This also marks the first consumer part to enable the entire GK110 Kepler GPU which now includes 2,880 cores (25% more than the original GTX 780) running at an 875 MHz base clock, 240 texture units, 48 ROPs and 3GB of GDDR5 running at 7.0 Gbps."

AMD Radeon R9 290 Shows Outstanding Performance for $399, Rivals $549 290X

Vigile Vigile writes  |  about 9 months ago

Vigile (99919) writes "AMD keeps releasing new GPUs, this time in the form of the Radeon R9 290, dropping the 'X' from last month's R9 290X. Based on the same Hawaii GPU that includes 6.2 billion transistors, a 512-bit memory bus and 4GB of GDDR5 memory, the R9 290 drops 256 shader processors (to hit 2,560) and 16 texture units compared to the 290X. However, due to a higher maximum fan speed, the R9 290 will likely run at higher out-of-box, sustained clock speeds than the R9 290X at default settings. As a result, the R9 290 is not only beating the $499 GeForce GTX 780 but rivals the R9 290X at $549. Considering the R9 290 will have an MSRP of just $399 starting today, that is going to sound awfully impressive to enthusiasts."

AMD Radeon R9 290X Fixes Pacing with New CrossFire

Vigile Vigile writes  |  about 9 months ago

Vigile (99919) writes "AMD is releasing its fastest single GPU graphics card today, the $549 R9 290X based on a new, 6.2 billion transistor GPU called Hawaii. The brand new part has 2,816 stream processors and has a peak theoretical performance of 5.6 TFLOPS. PC Perspective has done a full round of testing on the card to see where it stacks up and it does in fact beat the GeForce GTX 780, a card that costs $100 more. In fact, it also compares well to the $999 GTX TITAN flagship. Maybe more interesting is the completely redesigned CrossFire integration that no longer uses a bridge and fixes the CrossFire + Eyefinity/4K pacing issues that have plagued AMD for some time. As it turns out, with this new hardware, 4K tiled display CrossFire appears to be corrected."

AMD Radeon R9 280X, 270X, 260X Reviewed

Vigile Vigile writes  |  about 10 months ago

Vigile (99919) writes "Last month AMD publicly shared plans to release a new line of graphics cards including the R9 and R7 series of Radeon GPUs. Today is the first step in that product release with the Radeon R9 280X, R9 270X and R7 260X cards going on sale and being reviewed. PC Perspective has tested all three and compared them to the latest offerings from NVIDIA and found the 280X and 270X to be first class products that offer nearly unparalleled performance per dollar. The $299 Radeon R9 280X is often outperforming the $399 GeForce GTX 770 and the R9 270X at $199 bests the GTX 760 at $249 many times as well. Enthusiasts might be disappointed to learn that all three of these cards use existing silicon previously found in the Radeon HD 7900/7800/7700 series and they will have to wait a bit longer before the hyped AMD Hawaii GPU appears."

Multi-Display Gaming Artifacts Shown with AMD, 4K Affected Too

Vigile Vigile writes  |  about 10 months ago

Vigile (99919) writes "Multi-display gaming has really found a niche in the world of high-end PC gaming, starting when AMD released Eyefinity in 2009 in three panel configurations. AMD expanded out to 6 screen options in 2010 and NVIDIA followed shortly thereafter with a similar multi-screen solution called Surround. Over the last 12 months or so GPU performance testing has gone through a sort of revolution as the move from software measurement to hardware capture measurement has taken hold. PC Perspective has done testing with this new technology on AMD Eyefinity and NVIDIA Surround configurations at 5760x1080 resolution and found there were some substantial anomalies in the AMD captures. The AMD cards exhibited dropped frames, interleaved frames (jumping back and forth between buffers) and even stepped, non-horizontal vertical sync tearing. The result is a much lower observed frame rate than software like FRAPS would indicate and these problems will also be found when using the current top end dual-head 4K PC displays since they emulate Eyefinity and Surround for setup."

Intel Bay Trail Brings New Architecture and Performance to Atom

Vigile Vigile writes  |  about a year ago

Vigile (99919) writes "Today at the Intel Developer Forum in San Francisco, the company officially released the Atom Z3000 series of SoCs (Bay Trail) based on the Silvermont architecture. Unlike previous Atom designs, the Z3000 and Silvermont is a completely re-architected product from the ground up and is no longer based on legacy processors. Changes include a move to an out-of-order x86 architecture with drastically improved single threaded performance but the removal of Intel's HyperThreading technology. Dual-core modules with 1MB of shared cache can be paired up to create a quad-core SoC that also includes upgraded graphics design. Intel is no longer depending on PowerVR for a GPU and has integrated a 4 EU (execution unit) Intel HD Graphics design that is very similar to the one used in Ivy Bridge. As a result, as tested at PC Perspective in both Windows 8.1 and Android 4.2.2, the Bay Trail part is as much as 4x faster in single threaded tasks and 3.5x faster in gaming and graphics. Power consumption remains nearly the same as it did with Clover Trail (Atom Z2760) but with improved power gating and support for Connected Standby, Intel's new Atom looks and feels completely different than any before it."

AMD releases 13.8 beta driver to implement frame pacing support

Vigile Vigile writes  |  about a year ago

Vigile (99919) writes "Over the past year AMD has been getting hammered over its CrossFire technology and the issues the multi-GPU scaling solution has with frame pacing — the ability to present frames evenly to the user and create a smooth gaming experience. As new tools have become available to evaluate the performance of graphics solutions (like capture cards and overlays), the battle between CrossFire and NVIDIA's SLI has really taken new life. After denying the problem existed for quite some time, AMD has put out the first beta driver that implements a software frame pacing solution to more evenly produce animations from CrossFire configurations. PC Perspective has done extensive testing with the Catalyst 13.8 beta and found that it has basically solved the single screen pacing problems. More trouble remains for AMD though as they still need to find a way to fix Eyefinity and 4K displays that are exempt from this driver's improvements."

NVIDIA SHIELD is first with Tegra 4, merging mobile and PC gaming

Vigile Vigile writes  |  1 year,11 hours

Vigile (99919) writes "First shown at CES in January, NVIDIA SHIELD is a purpose built Android gaming device with a few interesting features that help it stand out from your normal phones or tablets. First, it is the only available device to be powered by the Tegra 4 SoC, NVIDIA's latest processor. Second, it merges a console-grade controller with a 5-in touch screen in an attempt to standardize Android gaming with reliable and solid input. Third, users with GeForce GTX graphics cards can stream PC games on their home network to the SHIELD to play games remotely. PC Perspective has published a review of SHIELD and found that not only is Tegra 4 incredibly powerful but that SHIELD actually makes Android gaming interesting for the first time."

New Samsung 840 EVO with TurboWrite TLC Technology

Vigile Vigile writes  |  1 year,6 days

Vigile (99919) writes "Samsung continues with strong releases into the SSD market with the new 840 EVO today. Based on the same TLC (triple level cell) flash that the original Samsung 840 drive used when it launched last year, Samsung has improved the write speeds of this new drive by implementing something called TurboWrite. By accessing a portion of that TLC memory as if it were SLC, it can be written to much faster that MLC or TLC allowing the drive to dump all writes to that area initially and then migrate the data to TLC when idle or when the cache is full. Initial write speeds of this write-back cache can be as high as 520 MB/s but after it's full (during sustained writes) it will drop to as low as 140 MB/s. Through testing at PC Perspective they found that average "flush times" of the cache will change based on the drive capacity and cache sizes which range from 3-12GB."

ASUS PQ321Q Monitor Brings Multi-Stream Tiled Displays Forward

Vigile Vigile writes  |  1 year,11 days

Vigile (99919) writes "While 4K displays have been popping up all over the place recently with noticeably lower prices, one thing that kind of limits them all is a 30 Hz refresh rate panel. Sony is selling 4K consumer HDTVs for $5000 and new-comer SEIKI has a 50-in model going for under $1000 but they all share that trait — HDMI 1.4 supporting 3840x2160 at 30 Hz. The new ASUS PQ321Q monitor is a 31.5-in 4K display built on the same platform as the Sharp PN-K321 and utilizes a DisplayPort 1.2 connection capable of MST (multi-stream transport). This allows the screen to include two display heads internally, showing up as two independent monitors to some PCs that can then be merged into a single panel via AMD Eyefinity or NVIDIA Surround. Thus, with dual 1920x2160 60 Hz signals, the PQ321Q can offer 3840x2160 at 60 Hz for a much better viewing experience. PC Perspective got one of the monitors in for testing and review and found that the while there were some hurdles during initial setup (especially with NVIDIA hardware), the advantage of a higher refresh rate made the 4K resolution that much better."

GeForce GTX 760 marks NVIDIA's 6th based on GK104

Vigile Vigile writes  |  about a year ago

Vigile (99919) writes "With today's release of the GeForce GTX 760, NVIDIA has now built a total of six individual graphics cards based around the original GK104 GPU proving that you can get a lot of value out of a silicon investment if the market plays out correctly. Kepler has been wildly successful for the company by improving performance per watt quite dramatically over the GF100 Fermi designs and the new GTX 760 completes the life span of the design quite fittingly. With 1152 processing cores and a 256-bit memory bus (running at 6.0 GHz) all packed into the same old 3.54 billion transistor chip, the GTX 760 is running quite a bit faster than the competing Radeon HD 7870 GHz Edition and equally as fast as the Radeon HD 7950 with Boost. With a price tag of $250 it might finally bring the GK104 design down to price points that everyday gamers are willing to swallow as well."

AMD Making a 5 GHz 8-core Processor at 220 Watts

Vigile Vigile writes  |  about a year ago

Vigile (99919) writes "It looks like the rumors were true, AMD is going to be selling an FX-9590 processor this month that will hit frequencies as high as 5 GHz. Though originally thought to be an 8-module/16-core part, it turns out that the new CPU will have the same 4-module/8-core design that is found on the current lineup of FX-series processors including the FX-8350. But, with an increase of the maximum Turbo Core speed from 4.2 GHz to 5.0 GHz, the new parts will draw quite a bit more power. You can expect the the FX-9590 to need 220 watts or so to run at those speeds and a pretty hefty cooling solution as well. Performance should closely match the recently released Intel Core i7-4770K Haswell processor so AMD users that can handle the 2.5x increase in power consumption can finally claim performance parity."
