AMD Llano APU Review - Slow CPU, Fast GPU

Cornelius the Great Re:Who buys AMD? (184 comments)

I would argue that sharing cache between CPU and GPU is not necessarily ideal. Also, keep in mind that GPUs and CPUs use memory very differently; CPUs prefer low latency, GPUs prefer raw bandwidth- this is why Llano's graphics performance is very sensitive to the clockspeed of the memory you're using.

Open-Source Bach; Copyright-Free Goldbergs

Cornelius the Great Re:Why not MIDI? (106 comments)

MIDI is very limited. MIDI was set up 30 years ago as a communication interface, and by today's standards it's a poor one- you're limited to one note per millisecond. IIRC, you are also limited to 16 channels, so composing scores for an entire orchestra is out of the question.

To top it all off, it wasn't meant for music notation. Symbols like Accelerandos, Ritardandos are notably absent- changes to tempos are hardcoded. Many other symbols are absent as well. Sometimes notes need to be formatted in a special way (ie- for readability, or left/right hand on piano).

Anyone who has ever composed in Finale, Sibelius, etc and tried to export to midi will notice the limitations right away. Why, what's your beef with XML anyway?

Judge Lets Sony Access GeoHot's PayPal Account

Cornelius the Great Re:This has to stop (288 comments)

Please don't confuse capitalism with corporatism. The very fact that the Government would dictate or allow someone else to dictate what someone can and cannot do with his/her own property goes against one of the basic tenets of free-market capitalism. In a true capitalist system, Sony wouldn't be able to take legal action against modchip manufacturers.

"Intellectual property" is another concept that is falsely attributed to capitalism. The government should never enforce monopolies, especially over ideas.

Facebook May Bust Up the SMS Profit Cartel

Cornelius the Great Re:except (262 comments)

I don't know if you're being sarcastic, but in case you aren't...

Some Motorola Android phones have MotoBlur, which require a MotoBlur account (it does its own cloud syncing). My Atrix, unfortunately, is one of those phones.

I believe the Motorola Droid phones (Droid, Droid 2, Droid X) on Verizon don't have MotoBlur, and thus don't require a Motorola account.

Shoplifter Gets Caught When Her Mobility Cart Gets Stuck

Cornelius the Great Re:"Mobility Carts" (21 comments)

This kind of thing pisses me off. After having knee replacement a few years ago, I was hobbling around on crutches for a month- and shopping with a regular cart was a pain in the ass. There were times when I went to the grocery store and the "mobility carts" were all taken up by fatasses who could really use the exercise.

I've always wanted to tell them off, "Hey tubby, laziness and lack of self-control isn't a disability!"

I can't imagine how people with permanent disabilities would feel in that situation.

Saudi Students In US Seek Segregation By Gender On Facebook

Cornelius the Great Re:Uh, what? (353 comments)

No joke.

That's why there are "no gays" in Iran, as Mahmoud Ahmadinejad joked about on a previous US visit. Known homosexuals are either forced to have gender reassignment surgery, or risk jail or execution. It mirrors the way western countries forced gays to undergo chemical castration as recent as 50 years ago (like what happened to Turing), but it's terrible that this kind of thing still happens today.

iPad 2 Rumored to be in Production

Cornelius the Great Re:Please have a real stylus. (192 comments)

A capacitive stylus is more like writing with a crayon than a pencil. If you look at these, you'll quickly notice that they're not much more precise than your finger (unless you have really fat hands).

Loophole Means Unlimited Data For AT&T iPhone

Dual-Core Chips Coming To All Smartphones In 2011

Cornelius the Great Re:A4 is NOT just a Hummingbird (244 comments)

You're right, I was referring to the A8 core within the two SOCs. However, they both use the same PowerVR SGX 535 and were designed by the same firm (Intrinsity, which was acquired by Apple last year) in collaboration with Samsung. The A4 is slightly smaller, owing its decreased die size to smaller cache and other tweaks. Functionally, they're very similar, much moreso than any other A8-based SOC (TI OMAP, Qualcomm Snapdragon, etc).

Dual-Core Chips Coming To All Smartphones In 2011

Cornelius the Great Re:Can't see why "dual core" would be a selling po (244 comments)

1) The same argument was made before dual core made it to consumer PCs. If you build it, they will come.

In any case, waiting on either PC or phone is usually due to some IO task, not heavy CPU usage. By far, the most waiting I'm going to be doing is when web pages are being loaded.

Media playback and games are primarily where users will see the most benefit from dual-core in the foreseeable future. Having a heavy webpage with Flash running smoothly doesn't hurt either. :)

2) Today, chips have very good power-gating. If only one core is being used, only one core is being powered. Also, the power usage increase is logarithmic. For this reason, having a second core doesn't double the TDP of the entire chip.

Also, most of these dual-core chips add a fraction of die space in return for an extra core. The SOCs already only dedicate a minority of space to the ARM core- the rest is taken up by the GPU, Memory, radio, and other misc controllers.

And due to die shrinkages with every generation, many dual-core chips will be drawing less power than their single-core counterparts. Case in point: the 3rd generation Snapdragon with dual-Scorpion cores is claimed (at least by Qualcomm) to use less power than the Snapdragons in current smartphones. Going from 65nm to 45nm (28nm expected by end of 2011!) provides that kind of headroom.

Besides, the biggest user of battery space is usually the screen, then radio (wifi, 3G/4G, bluetooth, etc), then the CPU at a distant third.

Double core- Double battery usage? Right, whatever.

Dual-Core Chips Coming To All Smartphones In 2011

Cornelius the Great Re:Can't see why "dual core" would be a selling po (244 comments)

Why not? Multi-core was marketed successfully for PCs, what makes smartphones any different? Tech specs are pretty important to the Android crowd. Besides, now that certain devices will have docks that allow them become netbook and HTPC replacements, people will find uses for that extra core.

Dual-Core Chips Coming To All Smartphones In 2011

Cornelius the Great Re:iPhone already has dual core! (244 comments)

A4 is not dual core- it's an ARM Cortex A8 core with a PowerVR SGX 535 GPU. It's nearly identical to the Samsung Hummingbird CPUs used in the Galaxy S phones.

The 5th gen iPhone is rumored to have dual core, but it won't be out until at least this summer.

AMD CEO Dirk Meyer Resigns

Cornelius the Great Re:Sorry.. (123 comments)

I hate to break it you, but Fusion, Bobcat, and Bulldozer have been in development for quite a long time- all of these projects started when Hector was at the helm. Dirk can hardly be credited with these product releases, other than keeping AMD afloat long enough to allow these products see the light of day.

AMD CEO Dirk Meyer Resigns

Cornelius the Great Re:Hard call for GPU selection (123 comments)

Intel has also promised OpenCL support on Sandy Bridge and later integrated GPUs. Not to mention S3 and VIA support.

I predict that Cuda will quickly become irrelevant and die a long, slow death (ie- just legacy support, no new features). Much like Cg did, after GLSL and HLSL matured. No one wants to be stuck on a single hardware platform, despite performance advantages.

AMD CEO Dirk Meyer Resigns

Cornelius the Great Re:Sorry.. (123 comments)

I'll agree with this. AMD's been seeing some triumphs lately- their graphics division has been very successful, even despite a minor delay with the Radeon HD6900 GPU. Nvidia might have the performance crown this generation, but their previous generation has been shaky and their 40nm chips haven't been as available as AMD's, allowing AMD to gain considerable marketshare.

I've noticed a few netbooks with AMD Bobcat cores appear at CES, and has enough performance and power efficiency to give both Atom and Ion some serious competition.

While Llano doesn't appeal to me personally, it's nice to see Fusion reaching the desktop shortly. I'm also anxious to see how the Bulldozer will perform once it's released in a few months.

With the delay of Intel's Ivy Bridge into 2012, AMD has a lot of potential to make this year a profitable one.

PS3 Root Key Found

Cornelius the Great Re:The ridiculous problem is... (380 comments)

In a utopian future, people would pay the actual cost of manufacturing the console - plus a reasonable profit margin. Anyone could write games - and the cost of them would be reduced because they wouldn't have to pay the "Sony Tax" on each one. For people who'll own very few games over the life of the console, this is not so attractive - but for people who buy more than the average number of games, it's a huge win. But at least we're honest about it.

I already live in that future. I have a console hooked to my TV that runs code that doesn't have to be signed by Sony, Microsoft, Nintendo, et al. I can also run multiple OSes on it without having to jailbreak it. And I have hundreds* of legally-purchased games to play on it that probably cost me less than what 20 new PS3/360 games would (at $60).

It's called an HTPC. It pretty much does everything a PS3/360 does better (including blu-ray playback). Not to mention backwards-compatibility with at least a dozen of older consoles via emulators. I still have my PS3, but primarily for GT5 and not much else.

*My Steam account alone has 300+ titles. Mostly bought through holiday sale packs at a huge discount. I've probably played less than half so far, but I'm still discovering games that I bought more than a year ago.

Oxford Scientists Say Dogs Are Smarter Than Cats

Cornelius the Great Re:From the No-shit-sherlock department (716 comments)

I suspect that most cats understand the laser pointer, but play with it anyway. Much the same way that they can tell the difference between a piece of string and a snake and will go after it anyway. I don't think they're being dumb, they're naturally playful and enjoy the hunt.
