3.2 GHz PowerPC Tri-Core Xenon

that's Xbox 360's CPU.

My Pc is a Dual Core E2180 @2.00 Ghz.

I wonder why consoles need such powerful cpu's?????

it really isn't that powerful, your pc's cpu is probably about as good.

They aren't that powerful. There are a lot of components stripped from them to reduce costs and increase production yields.

In order execution vsOut of order execution.

I think John Carmack said the 3 cores are about the same a 1.5ghz in PC terms.

I got a laptop with that processor as well and it does not suck.

Yeah, processors from consoles are not directly comparable to desktop processors.

Again, the in order and out of order execution, plus what Wasdie said all account for the 360 CPU being much less powerful.

hmm I didn't know about it. it seems like they do it on purpose to "show off", like saying their console is so powerful just to impress their costumers

Depending on how they're coded for. I would assume software developed with them in mind would be a bit more efficient.

no wonder why 360 is blazing fast

Know what I find ironic is that people seem to forget your console or PC only operates as fast as its slowest component. In this case, usually your disc drive or hard drive. Only once you have essentially everything you need in memory stored on RAM will it matter.

Also both the 360 and PS3 suffer from a lack of ram being proportional to their processing power. I really think this generation would have been so much better if we had a gig of ram in each console.

Just think if the 360 only had 256mb of ram like they originally planned.

[QUOTE="topgunmv"]

[QUOTE="SparkyProtocol"] Ofcourse it would. That'd be twice the amount of RAM they use now.SparkyProtocol

From what I heard epic talked them into doubling it ya, presumably because 256 was causing too many bottlenecks with gears of war development.

OMFG my PS3 Cell CPU has 8 cores at 3.2ghz, tahts like an intel i7 965 with hyperthreading.

MY PS3 PWNS EVERYTHING :D

Are'nt console CPU's usually better at number crunching and running game codes? The Xenon has around a 100G.flops. The pentium 4 @3.2GHZ is around 14G.flops. A dual core CPU is around 25G.flops, give or take.

Consoles are long term static platforms. They have to be given the best out of the gate to future proof them for as long as possible.

Intel Core i7 XE 975 at 3.33 GHz will give you 101 GFLOPS (SGEMM 4K x 4K ).

IBM PowerXCell 8i (Cell, 65nm) will give you 164 GFLOPS (SGEMM 4K x 4K). Xbox 360 PPE X3's SGEMM scores wouldn't be pretty i.e. half speed and small L2 cache.

Both the PC and Xbox 360 follows heavy FP workloads being off-loaded to the GpGPU (with atleast gather/scatter features).

ATI Radeon HD 3870(RV670) with 320 SPs reaches ~300 GFLOPS (SGEMM). http://developer.amd.com/gpu_assets/IUCAA_Pune_PEEP_2008.pdf

ATI Radeon HD 4870(RV770) with 800 SPs reaches ~1TFLOPs (SGEMM 4K x 4K, ~81 percent from peak). http://forum.beyond3d.com/showthread.php?t=54842

Clock speed is pretty much irrelevant when comparing different architectures. PS2_ROCKS

imprezawrx500

That's a pretty terrible example. You could easily flip that and apply it to the poor performance of gta4 on computers. Bad coding isn't the same as bad hardware.

true they are good at number crunching, but not really better at running game code.imprezawrx500

quake 4 is the perfect example. could hardly maintain 30fps.
imprezawrx500

plus if you want number crunching use the gpu. any current gpu will kill the cell or 360 cpu.

If you consider the specs of the original Xbox (700mhz Celeron) and how it could do Ninja Gaiden 2, console specs really aren't as much of a big of a deal as code optimization.

Not in 32bit FP (which is what the Cell was designed for), the Cell is still king king with ~30% better single precision FP performance than even the i7.

imprezawrx500 was referring to "number crunching" not running an OS.

The I7 sucks for graphic rendering purposes.
