Ok, it's game on then.
[QUOTE="trasherhead"][QUOTE="ronvalencia"] Note that Xbox 360 Slim has fused it's PPE X3 and ATI Xenos into one chip package.ronvalencia
Still can not come colse to what this card can pump out even at stock settings. Even 3 Xenos GPU's aren't even in the same League.If 6 SPEs = "3 Xenos GPUs", how come ATI Radeon HD 1950 smashes PS3 CELL almost twice over on Fold @ Home?
Where's G71 SLI killing PS3 Quake III benchmark scores (OpenGL on SPEs)?
On http://research.scea.com/ps3_deferred_shading.pdf
5 SPEs just under G70 on deferred pixel rendering. Where your CELL = "3 Xenos GPU"? Remember "Xenos" refers to the ATI's GpGPU.
If 6 SPEs = "3 Xenos GPUs", why bother with RSX/G70 at all? I recall the initial PS3 was all about CELL and later it would not be enough against "one trick pony" NVIDIA and ATI.
Are you claiming CELL = 3 G70 in SLI mode? This is BS and you know it.
I have already debated with Nicko in amigaworld.net and amiga.org. Unlike RSX/Geforce 7, ATI Xenos is not "just" a GPU.
For example, on the subject on
1. architectural registers, X86-64 has architectural registers count similar to another RISC ISA it's called ARM.
2. Intel Itanium, refer to Intel Core 2.
On Xbox 360 vs PS3, David Shippy's statement factors in "The GPU is highly sophisticated in the Xbox 360". http://www.gamasutra.com/view/feature/3904/processing_the_truth_an_interview_.php?page=3
"I'm going to have to answer with an 'it depends,'" laughs Shippy, after a pause. "Again, they're completely different models. So in the PS3, you've got this Cell chip which has massive parallel processing power, the PowerPC core, multiple SPU cores… it's got a GPU that is, in the model here, processing more in the Cell chip and less in the GPU. So that's one processing paradigm -- a heterogeneous paradigm."
"With the Xbox 360, you've got more of a traditional multi-core system, and you've got three PowerPC cores, each of them having dual threads -- so you've got six threads running there, at least in the CPU. Six threads in Xbox 360, and eight or nine threads in the PS3 -- but then you've got to factor in the GPU," Shippy explains. "The GPU is highly sophisticated in the Xbox 360."
He concludes: "At the end of the day, when you put them all together, depending on the software, I think they're pretty equal, even though they're completely different processing models."
Let's see 4 SPEs matches ATI's Tessellation hardware i.e. SPEs are not hardwired for Tessellation. You then have RSX's vertex shader bottlenecks.
Examples,
1. RSX doesn't support DX10's 3DC+ texture compression.
2. RSX doesn't have decoupled pixel shader and texture unit design i.e. causes a pixel shader to stall during a texture fetch.
3. RSX doesn't have unified shaders for vertex shading. "Unified shaders" combines vertex shader and pixel instruction sets.
4. RSX's MSAA hardware doesn't have HDR FP support.
5. RSX doesn't have Tessellation (Geometry) hardware.
6. RSX doesn't have competent Early-Z cull hardware.
7. RSX doesn't have competent shader branch unit hardware.
8. RSX doesn't have ATI's memport hardware. Useful with vertex shader programs as with the capabilities to scatter and gather to and from system RAM the graphics processor suddenly becomes a very wide processor for general purpose floating point operations(1).1. http://www.beyond3d.com/content/articles/4/10
With the capability to fetch from anywhere in memory, perform arbitrary ALU operations and write the results back to memory, in conjunction with the raw floating point performance of the large shader ALU array, the MEMEXPORT facility does have the capability to achieve a wide range of fairly complex and general purpose operations; basically any operation that can be mapped to a wide SIMD array can be fairly efficiently achieved and in comparison to previous graphics pipelines it is achieved in fewer cycles and with lower latencies. For instance, this is probably the first time that general purpose physics calculation would be achievable, with a reasonable degree of success, on a graphics processor and is a big step towards the graphics processor becoming much more like a vector co-processor to the CPU.
You going to have alot of workarounds for the 6 SPEs.
DUDE! Do you even know what and SVGA card is? Or a 386? Heard of sarcasm? Ok history time!
The 386 was an Intel cpu used in computers back in the 80's and the SVGA card was a 16 bit card that you needed to first play Sim City 2000.
This was before 3d accelorators.
And I don't see how you could confuse my statements for the RSX or the Cell. And if you read my posts a little closer I just said that they didn't even come close to eachother. So have a chillpill pn te house ;)
