Forums - Gaming Discussion - 360 CPU and Cell are fairly equal according to Dave Shippy

Yeah, 165 million transistors, 1MB of cache and 3 cores are indeed very similar to 300 million transistors, 2,5MB of cache and 9 cores. That's why everybody uses X360 as cluster supercomputers like PS3.

No seriously, at its very best the X360's CPU is 3,2 GHz x 8 FLOPS/clock cycle (as any IBM PPE) x 3 cores = 76,2 GFLOPS of peak performance.

PS3 has nine cores (1 PPE, 8 SPEs) at 3.2 GHz which means 230,4 GFLOPS of peak performance or 179,2 in-game processing power avaliable.

Oh and btw the RSX is also a bit stronger than the Xenos (4 alus x 2 madds x 24 pipelines + 5 alus x 8 pipelines x 550 MHz = 255 GFLOPS verse 5 alus x 48 pipelines x 500 MHz = 240 GFLOPS)

X360 multiplats look better most of time because X360 has more memory avaliable (more memory = bigger textures and frame buffer) and PS3 is harder to work. Plus most PS3 multiplats do not even work with the whole Cell at all (only its single general purpose core).

Your haterboxes.

Better read the whole article source. It's interesting:

Funny thing is, with all this hate going on in these threads, I have yet to see a PS3 game that trounces all 360 games in every aspect of performance, ditto for a 360 game.

To some people "trounces" could mean 20% better.  To others people "trounces" is basically an unreachable sliding bar that constantly changes based on whatever the top performing game is.

The reality of it is that Killzone 2 "trounces" ALL games before it except Crysis.  KZ2 "trounces" Crysis in SOME areas (animations, character models, characters on screen, gun models, particle physics, 7.1 discrete audio, etc) but is close in other areas and gets beat in other areas.  Killzone 2 uses the SPEs to achieve up to a 40% increase in GPU performance (WAY beyond the X360)!

 

Also, Shippy is only speaking of the part HE designed (the PPE of the Cell and the XeCPU cores of Xenon).  That's actually a good benchmark to use.  We know that in most cases of optimized code, the SPE can be around 3x faster than the PPE.

One guy said said something that was incorrect about the BD drive speed in the PS3 vs. DVD drive speed in the X360. Even though the X360 drive is a 12x DVD drive, it maxes out at 8x for DL-DVDs (almost ALL X360 games).  The X360 drive has to build up to that speed over the span of the disc.  The BD drive has a constant read speed across the entire disc.  This ends in the BD drive being just over 1MB/s faster than the DVD drive in the X360.

That was just for the people interested in learning.  The others will do what they do best (try to discredit these unversities' real world implementations and me).

Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.

*shakes head* That's exactly what I JUST talked about. You can't even break you're cycle.  It's to the point where I can post what those types of people will say before they say it.  THEN, they have to do it anyway, because they can't stop themselves.

euh... I'm confused now

@Ascended_Saiyan3,
Kill Zone 2 has great animations. To be honest - the best character animations I ever see in FPS game, but technically is not even near Crysis or Crysis Warhead. If you compare character without animations Gears eats it.

Character Models:

As you can see GoW2 offers more complex and detailed character models.

I could say "the sun burns at approx 250 degrees", and then guess what kind of responses I'd get. If I spread BS, I'm gonna get called on it.

 

Your statement about KZ2 "trouncing" all games before it it simply false. The poster clearly said in all respects, and KZ2 has graphical advantages, meanwhile it falls short in NUMEROUS other areas. We could make a list of features that are available in games like CoD or Halo that KZ2 had to cut/leave out in order to achieve the graphics benchmark it wanted. How good would Halo 3 look if they hadn't accounted for 4 player split screen or Coop? Much better. But many games opt to extend the gaming experience instead of being able to put out the prettiest screen shots. KZ2 trounces other games in the graphics department, but don't for a second think that the total package is unmatchable.

This guy was the leading man behind both consoles' CPU's? Wow?

 

EDIT: I thought the Cell was supposed to be amazing, which is partly why Sony spent so much damn money on it. I'm assuming that in other ways it's vastly superior to the 360 CPU, correct?

 

For non-gaming tasks, yes.
