Intel Pushes Into Tablet Market, Pushes Away From Microsoft

edxwelch Maybe growth, but not profit (54 comments)

Intel are determined to sell 40 million of their tablet chips, but they certainly aren't going to make any profit, because of "contra revenue".
"Intel is charging customers about the same as Allwinner and Rockchip for tablet CPUs â" $5 a pop, reports Digitimes"
http://www.electronicsweekly.c...

No surprise that their mobile group lost nearly $1 billion last quarter.

edxwelch OpenGL renaissance? (241 comments)

I think we could see a new OpenGL renaissance, because of Steam OS and OpenGL ES being used in mobile games.
I saw a post on the Unreal engine forums about how they intend to implement first class OpenGL support in the new engine. They really hate the way Microsoft tie DirectX updates with the OS. (You can see this post here -at very end: https://answers.unrealengine.c...)
Also, consider OpenGL 4.4 has had Mantle like features since last year which will only come out in DirectX 12 in 2015.

NVIDIA Unveils Next Gen Pascal GPU With Stacked 3D DRAM and GeForce GTX Titan Z

edxwelch Re:a few things left out (110 comments)

Similiarly there's no mention of a Tegra K1 SoC with LTE. I think this is a sign that Nvidia will shortly abandon the smartphone market. Without any CDMA, or TD-SCDMA in their modem support they can't sell in Chinese or American markets

AMD Develops New Linux Open-Source Driver Model

edxwelch Re:Does AMD still matter? (142 comments)

The console market is guaranteed cash in the bank, with no competition from any other player. There's few companies that have a deal like that.
And the margin is quite good considering that Microsoft and Sony shared in development costs.

That article for some reason ignores the last 2 quarters where AMD turned a profit. People have being saying AMD is finished for the last ten years, but yet it's still here.

Intel Announced 8-Core CPUs And Iris Pro Graphics for Desktop Chips

edxwelch Re:Iris Pro is a white elephant (173 comments)

What does that have to do with it? i5-4670K and i7-4770R have same amount of L1, L2 and L3 cache

Intel Announced 8-Core CPUs And Iris Pro Graphics for Desktop Chips

edxwelch Iris Pro is a white elephant (173 comments)

The eDRAM simply makes the chip way too expensive.
If you look at the price of i7 core 4770R: $358. It's an i7 but has only has 6 MB of cache (compared to the 8mb of the regular i7 4770). So basically, it's about the same value as a i5-4670K which cost $243. With the price difference you could buy a Radeon R7 260X, which will trash Iris Pro in performance.

I've heard a discussion about the possiblity that the plane broke free of gravity and flew into space, because of the light weight composites used in the contruction of the plane (I swear I'm not making this up)

How Do You Backup 20TB of Data?

I suspect that that won't work, because the entire disk become unreadable by the OS. I mean you can't even see the list of files

I do that as well, but I found out to my horror that all my DVD's had become unreadable over time. So, probably good idea to test your backups from time to time

Top E-commerce Sites Fail To Protect Users From Stupid Passwords

edxwelch Re:WRONG, timeouts suck (DOS vector) (162 comments)

It's quite easy to work around that small problem, if you implement the scheme with a small amount of intelligence. Some one trying to dos you will becoming from a different IP than the legit user, so you only time out if coming from the same domain.
And yes, cloudcracker was used to crack passwords: http://arstechnica.com/securit...

Top E-commerce Sites Fail To Protect Users From Stupid Passwords

edxwelch Need timeouts (162 comments)

Developers should protect the password from brute force cracking by putting a time delay after successive failed login attempts. It doesn't really matter how strong your password is, if the system allow unlimited login attempts then it's possible to crack using something like CloudCracker.

Yes, the Japanese were lucky the meltdown happened at the same time as the tsunami. As the tsunami is worse, then the meltdown "doesn't count." Hurray for the amazing logic of pro-nuke fanboys.

OpenGL 4.4 already has DirectX 12 and Mantle-like features

edxwelch edxwelch writes  |  about a month ago

edxwelch (600979) writes "The announcement of DirectX 12 was a big focus of attention at GDC yesterday. The new API will bring Mantle-like low level access to the hardware, reducing the CPU overhead.
The OpenGL talk "Approaching Zero Driver Overhead in OpenGL", on the other hand, received considerably less media attention. The OpenGL camp maintains that the features to reduce CPU overhead are already present in the current version. They suggest using the extensions such as, multidraw indirect combined with bindless graphics and sparse textures, OpenGL can get the similiar "close to the metal" performance as Mantle and DirectX 12."

Intel engaged in below cost selling

edxwelch edxwelch writes  |  about 2 months ago

edxwelch (600979) writes "An analyst at Bernstein Research has found that Intel is selling their tablet Bay Trail chips to OEMs below cost, concluding that after end rebates, Intel’s tablet revenues are likely to be “close to zero,” while profits will be negative.
Intel has responded that the “special costs” Intel is incurring are not pushing down gross margin.
Intel needs to offer the subsidies to OEMs building $199-$299 devices to bring the bill of materials down and make them competive with cheaper chips from the likes of MediaTek and Rockchip."

AnTuTu benchmarks optimized to favour Intel

edxwelch edxwelch writes  |  about 9 months ago

edxwelch (600979) writes "A recent report by ABI research showed Intel's Clover Trail+ outperforming SoCs from Samsung, Qualcomm and Nvidia.
However, a EETimes article casts serious doubt about the validity of the report, in particular the AnTuTu benchmark used to test the chips.
"Going from the 2.9.3 version of the AnTuTu benchmark to the 3.3 version, the overall AnTuTu scores increased 122 percent, and the RAM score increased 292 percent for the Intel processor, while the scores for the Samsung processor increased only 59 percent and 53 "
To top things off, somebody analyzed the assembler code in the AnTuTu benchmark and found clear evidence that the benchmark had been tweaked to favour x86 processors."

The real reason Firefox lost to Chrome: Firefox 4

edxwelch edxwelch writes  |  more than 2 years ago

edxwelch (600979) writes "In November last year Chrome overtook Firefox in market share for the first time. What people don’t realise is that the release of Firefox 4 caused a large part of the decline.
Firefox 4 was a major new release and came with a brand new Javascript engine and HTML5 parser. Unfortunately, these new features came with major memory leaks and performance bugs. The result was that if you used Firefox 4 for an extended period of time the browser would eventually become unresponsive, making it virtually unusable."
