Default Xbox360's ATI Xenos GPU has more transistors (332M) than PS3's Nvidia RSX GPU (300M)

it was first reported, back on May 12th, that the Xbox 360 GPU which used to be called R500, had only 150 Million transistors.

the GPU, the Graphic Processing Unit, which handles the graphic output of the system (and which has 150 million transistors in it),
very odd concidering that ATI's 1+ year old R420 in Radeon X800 has 160M.


now it has become known that the Xbox 360's ATI GPU is not called R500. it is called Xenos.

Xenos has 2 seperate dies on one package. the main 'parent' GPU die where most of the processing gets done--has 232 million transistors. the 'daughter' die which consists of eDRAM plus 192 sub-processors for anti-aliasing, plus z/stencil and (i think) alpha blending hardware-- has the other 100 million transistors. total transistors for the entire Xbox360 graphics subsystem / GPU package, is 332 million transistors.

Lastly, we were sent updated spec numbers on the Xbox's numbers, and we spoke with Microsoft's Vice President of hardware, Todd Holmdahl, about the Xbox 360's final transistor count.

Another bit of information sent our way is the final transistor count for Xbox 360's graphics subset. The GPU totals 332 million transistors, which is spit between the two separate dies that make up the part. The parent die is the "main" piece of the GPU, handling the large bulk of the graphics rendering, and is comprised of 232 million transistors. The daughter die contains the system's 10MB of embedded DRAM and its logic chip, which is capable of some additional 3D math. The daughter die totals an even 100 million transistors, bringing the total transistor count for the GPU to 332 million.


Nvidia's RSX 'Reality Synthesizer' GPU for Playstation3 has 300 million transistors, and no super-high bandwidth eDRAM to take the load off of the main memory bandwidths in PS3.


Xbox 360 GPU is not the puny 150M transistor part that it was thought to be last week.

The 10MB E-dram adds a lot to the transistor count. Come to think about it, appox 50 million for 1 mb? That would be 500million for the edram alone? I dunno how edrams are well made up etc so the transistor count might be different to a L2 based calculation/guess i made. So i dunno maybe teh r500 does have more transistors...it does have 48 unified shading pipelines.

yes but that is eDRAM and transistors that PS3's RSX does not have

Since they're around the same Transistor amount...ya...RSX does have. And it's probabley putting them to better use.

So xbox360 owns ps3 hardware wise. I though developers were saying ps3 was slightly more powerful?

right, and just because the Pentium4 had more transistors than the AthlonXP I guess the AXP just sucked too right?

gah, what a stupid lame retarded ignorant arguement

I read that the x360's gpu acts as the memory controller as well... so that has to add to the transist. count. we still don't know all the details about the rsx though.

edit: the x360's gpu is split into two die's... parent and daughter die's. so, does this mean that ati's future desktop chips will have a second die for embeded ram and other functions?? This all compared to a single die 300mil gpu in the ps3.

The 332 will be because it has a so called 'unified' architecture IMHO - those unified shader units are bound to be more complex than traditional ones.

And how stupid and lame of Sony to have Nvidia come out and make such grand statements about their transistor count

If Nvidia wants to make it sound like transistor count makes the better chip, then I think the argument becomes relative, even if it's wrong

i agree with kev on this.... The sony hype machine is up to it again.

Sony's much better at hype than Microsoft, they were last generation and we all know whose machine is more powerful.

Looks like you didn't bother watching the press conference. They didn't say more transistors = better performence, they simply used the more transistors thing as a jumping off point to explain all the new things they could do with the RSX.
