Does 150 million transistors in GPU of Xenos matter?

[hasanahmad]

Is it less because of difference in architecture or am i ignoring the EDRAM Transistors

 

[Hardknock]

EDRAM transisters boosts the total count to over 300 million.

 

[hasanahmad]

does anyone have a link to how many total transistors Xbox 360 GPU has and how are they distributed?

Just go read it.

 

[SanGreal]

The parent die is 232M transistors and the daughter die is 105M transistors

 

[hasanahmad]

thanks. just needed to clarify from you guys for my blog

No offense, but sometimes people at GAF can be such IDIOTS. Check out this thread:

The OP doesn't even have the transister count for Xenos right!!! And then he later states the RSX will have 400 million transisters! When it's been officially confirmed to only have 300 million! People are just CLUELESS, and everyone there is just going along with it. Geez...

That thread is from 5/13/05 when not much was known about either chip

haha, I see now. That forum never seizes to amaze me though.

Stop slamming other forums on this board. This is a place for construction discussion on a variety of topics, but that does not include talking about other forums in a negative light on here.

The real mystery is why that ancient thread was bumped. It was like Deja Vu up the wazoo there for a minute....

I would say that the transistor that are dedicated to the daughter die and it's logic do matter. A lot of work goes on there. So while it is a different design from other architectures, a lot of thought went in to where to invest transisters. I would't discount them because it is 'just' eDRAM.

Then again, the NV40 has a lot of transistors that go unused most of the time, and others that just don't work (Video Processor WMV acceleration), so...

 

[BenQ]

Depending on where you look I have seen transistor numbers for the Xenos range from 332 millon to 382 million.

 

[Sonic]

And just where have these differeing numbers come from BenQ? I would like to see the sources for the varying of the transistor count.

I don't have the links to what your asking for, but I have read a WIDE range of transistor counts for the Xenos. Months ago, IGN was claiming it was 150 million. And then with Dave's article there was confusion about EXACTLY how many transistors comprise the daughter die. Has the Xenos article been editied since then?

ATI have clarified the daughter, eDRAM/sample logic die count to be 105M transistors.

Is the Edram side of the GPU a core all by itself, which makes the Xenos GPU a two core GPU setup?

Read the article. There is a pic of the package in there, with the VPU at the center and the eDRAM next to it.

 

[Shifty Geezer]

Depends what you mean by core. Core kinda implies a substantial amount of logic, whereas the eDRAM only has a smattering. But it is a seperate processor. Really a matter of personal preference I think.
