Playstation 3 e3 thread 2

That's not saying much. 2x 6800 Ultra is less than I'd be expecting. a 24-pipe 6800 refresh @ 533Mhz would yield 2x the fillrate of the 6800 Ultra.

I'd be looking for them to add HDR MSAA, fix dynamic branching a little, better AA, more HDR texture formats, etc.

Currently, a realtime demo of the Unreal 3 engine is being shown, running from a PS3.

It also has over 300 million transistors

I was right even on this

" The nVidia-powered graphics are twice as powerful as a GeForce 6800 Ultra. "

"Sony also unveiled the PS3's graphics chip, the RSX "Reality Synthesizer based on Nvidia technology. The GPU will be capable of 128bit pixel precision, 1080p resolution, some of the highest HD resolution around. It also has over 300 million transistors lager than any processor available commercially today. It was manufactured using the 90nm process with 8 layers of metal. The RSX is more powerful than two GeForce 6800 ultras, which would cost rough $1000 if bought today. "

Its G70 @ 90nm.

Ok, I'm feeling alittle happier after reading that. It means they've really put thought into HDR and Hi-Def. What about AA and shaders tho?

But 128-bit framebuffers? Are they mad? They don't have the bandwidth for that... unless...nah....512-bit GDDR memory bus?

That GPU looks like PC part GPU to be honest. Just adapt it to Cell.

It looks like a rush job, the PS3.

That'll be fairly common soon (it terms of hardware actually doing it), IMO...

Phil Harrison has just stated that there will be "an amazing surprise at the end of the show".

Hmm... that hasn't been confirmed, 22.4 GB/s is assuming 128bit bus...512bit sounds to high...

 

[Evil_Cloud]

New GTA at PS3 launch
160GB removable HDD, bigger HDD's might come in future

 

[nAo]

GPU needs at least 40 Gb/s with fp buffers + AA

 

[jvd]

it could be something that is there for the pc part and will never be used on the ps3 but wil lbe great for marketing speak

Well, we still don't know what's in it!

I thought 22.4gb/s was the FlexIO bandwidth between CELL and GPU, not the bandwidth between GPU and its memory.

 

[UKt@xman]

How does the Xgpu stack up against the RSX? Isn't the XGPU more than twice the power of a 6800ultra?

Like the black and the white, not the silver.

 

[nAo]

aggregated BW between CPU and GPU should be almost 80 GB/s

it's 700mhz GDDR (1400MHz effective) * 128bit bus (assumed) ~ 22.4 GB/s

FlexIO ~ 77 GB/s (45 GB/s out, 32 GB/s IN)
