PS3's Cell CPU tops high-performance computing benchmark

A UC Berkeley paper [PDF] recently submitted to the IEEE International Parallel and Distributed Processing Symposium manages to highlight two common and seemingly unrelated themes that have come up a number of times over the past few years in my reporting on the high-performance computing (HPC) space: 1) IBM's Cell is really good at HPC workloads when you invest the time to write custom code for it, and 2) Intel's Xeon platform is perennially bandwidth starved and not very power-efficient.

That's my PS3 and my PC(CPU) 1 & 2 :)

But like they explain, the benchmark test was written exclusive for the Cell as its architecture is vastly different from the others, but it seem the Cells knight in shining armor is the RDRAM.

Hey, me too. I have an old Xeon 1.7 ghz with 256 MBs rdram. I put Ubuntu on it and use it as a media server and for worry free web browsing. Just wish I had $150 to waste on expanding that expensive @ss ram.

is that proponents of Microsoft's machine always tout on about how the PS3 is "bottle-necked" for memory, and thus stifled in terms of performance.

In this study (which won an award, mind you), the Xeon was the processor most affected by memory, not the Cell. Aren't the processors in 360s some variant of Xeon architecture?

If so, it pretty much negates all those 'PS3/bottle-neck/ memory' rants, as the 360s on the short side of the stick here.

I'm not looking to flame, just looking for information.

Its probably true. The cell is capable of doing the jobs of other components. Its like how the ps3's gpu is less powerful then the 360's gpu, but it doesn't matter because the Cell is capable of doing part of the gpu's job. It's quite evident graphics aren't a problem for the ps3 when you look at some titles out. All i want to know is why does my ps3 crash about 2-3 times a day? Because im sure it has something to do with the memory usage. It happens most when surfing the web and it happened to me yesterday twice during folding@home and i lost about 40000 work units. It does my head in

TheMART6628d ago

Well Sony first thought the Cell could do all the GPU's tasks. But they found out the Cell is better for streaming video purposes and they had to put in a real GPU in the end. Thus costs were added, a high priced PS3 was born...

Shadow Flare, your PS3 crashes 2 to 3 times a day? Really? Damn! Which PS3 did you buy? News is coming in that the 40GB PS3 for the pricecut is build on cheaper stuff and has more hardware problems (BR drive that won't read games anymore soonish, crashing consoles etc.)

"Its like how the ps3's gpu is less powerful then the 360's gpu, but it doesn't matter because the Cell is capable of doing part of the gpu's job."

Oh god, give that BS a rest.

actas1236628d ago

@the mart
You are talking out of your ass.

Shadow Flare6628d ago

Actually i have the 60gb euro PS3 on launch day and have installed it with a 160gb hard drive. Mart, i wouldn't talk about the 40gb ps3 having 'cheap' parts because, you have an xbox 360. End of

And Meyers, i read that in an article like this one months ago. You're not even worth giving a decent response to since you have absolutely no knowledge of the cell processor at all. Take a hike

meyers6628d ago

"is that proponents of Microsoft's machine always tout on about how the PS3 is "bottle-necked" for memory, and thus stifled in terms of performance."

Not really surprising, most Dreamcast fans went on to become Xbox fans after the death of their system. Dreamcast fans were exactly the same way - they always had 'numbers' or 'charts' that 'proved' how much better their system was. And that all those amazing looking PS2 games 'could easily be handled by the Dreamcast' and 'just really good developers and not anything to do with the PS2 hardware'.

Same old, same old.

MaximusPrime6628d ago

when i had xbox 360, it crashes dozens of times within first 2 months before i sold it. Yes it was brand new.

Now i have PS3 for a year and 2 months, it only started crashing when i first played Burnout paradise (which is about 5 months ago)
It crashes a few times. WAAAY LESS than xbox 360.

So im still happy with my PS3. I dont regret selling xbox 360 after just 2 months.

Silverwolf6628d ago

Did you call Sony's support line? You might also want to grab a can of compressed air and clean it out. It just might be overheating due to dust buildup.

You're confusing two different things there. One is memory bottleneck in terms of how fast you can feed the processor. That has to do with memory latency, memory speed, the way the CPU is feed the data, etc, and how that affects performance. Its a "performance limitation due to memory botlenecks" that is beying talked here and in that sense the Cell does very well.

Another thing is talking about the total memory available for the system and how that limits the amount of features (e.g. in a game). In that case the PS3 suffers more than teh Xbox360 due to a bigger OS and non-unified memory.

Two very different things.

sonarus6628d ago

The thing is no matter how much people chatter about this and that, most of us here don't really know sh!t about either architecture.

That is why only the games can prove.

Varsarus6628d ago

The RSX is more than what you think it is, you just wait a few months then you'll see why

DJ6628d ago

The PS3 OS uses slightly more RAM than the 360's OS, but actually uses far fewer CPU resources. Also, the API used on PS3, Open GL 2.0 ES, is faster and more efficient than Microsoft's solution, DirectX 9.0c.

The other piece of information you got wrong is "PS3 suffers from not having unified memory." It's actually the 360 that suffers for not using chip-specific memory; it uses GPU RAM for both the CPU and GPU, which bogs down performance significantly. PS3 actually does have a Unified Memory Architecture, only that it uses chip-specific memory (CPU RAM for the CPU, and GPU RAM for the GPU) and has dedicated bandwidth lines to each pool of memory rather than constraining both chips to just one line, as in the 360. The 35GB/s connection between these two chips (and their respective memory pools) is the reason PS3 has so much emphasis on CPU-GPU communication.

For example, Burnout:Paradise uses the SPUs for anti-aliasing, Warhawk uses the SPUs for Volumetrics, and Killzone 2 uses both chips to support its dual graphics rendering engines (one is forward rendering, and the other is deferred rendering).

DJ:

I don't agree. I could further comment, but already did that in another thread here and honestly I'm tired of explaining things. At least you did reply and I thank you for that, which is much more than the general disagrees from fanboys that know as much about hardware as my grandma.If you want to know why I disagree search for a topic on XDR memory here at N4G.

Suffice to say that you are mixing memory acess/speed and its influence on the feeding of the processor during code crunching with issues derived from available total memory in the system. This article has nothing to do with available system memory, it has to do with how memory interacts with the system in terms of cache, speed, latency, etc. Thats why theres no factoring at all to how much ram was available to either processor durinf testing.

You are right about what you said. But that is not what I was talking about if you read my previous post.

Again, thank you for your comment. Bubbles for you. At least its possible to have a normal conversation with you :)

The knock on the PS3 is that there is a bottleneck on memory capacity, because of the way the 512MB is split. The knock on the Xeon archictecture is not capacity (these machines usually have GB's of Ram, tons of it) but bandwidth. It can't feed the cpu fast enough. Huge difference. And I don't think they were testing a PS3 anyway.

In regards to your second statement, no the 360 CPU, made by IBM who also makes the Cell (with sony and toshiba) is called the Xenon which may have confused you with Xeon. Xenon is a PowerPC derived CPU I believe. The Xeon (just the commercial workstation/low sever name) is an Intel processor, usually a beefed up version of the consumer CPUs, in this case Core 2 Duo/Quads etc. In this test it was the Clovertown (which is kind of old, the Harpertown cpus are newer). Think of Core 2 Quad beefed up. The reason for the memory bandwidth deficiency is chipset related. Intel still using hte old FSB and external memory controller. This becomes a problem when you have 8 cores and even SMT to deal with (in the future).

Intel is solving this with Nehalem based Xeons (forget the server codenames). Reason for the power consumption is becauseintel requires FB-Dimms, which are power hungry.

gnothe16628d ago

no chris this is not the same xeon as in the 360, the xbox chip is called XENON, the 360's chip is made by ATI not Intel. IBM made both processors for the 360 an PS3 but Nvidia made the GRAPHICS chip for the PS3( cell doesnt do the graphics) an ATI made the graphics chip for the 360!!

Kaz Hirai6628d ago

The Cell will instill discipline in our children! Everyone will know discipline!

42 days until Judgment Day, Nazisoft!

MWAH-HA-HA-HA!!!

alexM6628d ago

being 1/20 as powerful as the CELL

XENON doesnt even compare aginst EMT64--intel's processor of late 2004

miked8086628d ago

Read the Paper Ken its not Sonys CELL its IBMs CELL that is tested. The paper clearly states its the CELL Blade which is different then the one in the PS3 but you should know you helped develop it.

Pain6628d ago (Edited 6628d ago )

Sony's Cell Is IMB's Cell.... they joint made the Chip guy its the Same.

back to Xbox Fud with u.

oh and but but but teh Cell cant be Good.....its a Sony.... crys the xbot...

alexM6628d ago

haaa ha what an ABNORMAL XBOT

It is not SONY/IBM's CELL

CELL is made by STI

what a TARD haa haaaaa . The CELL architecture remains the same no matter produced by WHICH company

Not looking good. Hopefully Asha Sharma is able to turn Phil’s disaster around.

dveio55d ago

To me it's still quite remarkable how they can cash-in 5.3bn in revenue in a single quarter, since their hardware is basically dead.

Jingsing55d ago

The stock mark is what makes Microsoft remarkable, They have convinced every institutional and retail investor to just keep piling money into them. Like many big tech giants they are just a big growing pyramid scheme. As long as people keep dropping money into ETF's that cover the market Microsoft will always be liquid. At the same time it is completely stifling innovation and competition. People need to start being more discreet in how they invest their money as it's killing the system.

Tanktopmaster9255d ago

Once they re-evaluate exclusive all will be fine….

S2Killinit55d ago

Riiiiight because people will just flock back to them for one or two games per year.

Jingsing55d ago

15+ years of bad performance is what they call irreparable in business. It is time for them to sell off the assets and get out of entertainment.

Tanktopmaster9255d ago

These declines are on the back of extra revenue received from releasing games like Forza horizon 5 on PlayStation. So I’m being sarcastic here when I said they should go back to exclusives. Killing off a revenue stream from Ps5 sales will only make things worse
