AMD Discloses More Details About Sony PS4 System-on-Chip.

My thoughts exactly STEvil

So it's true, Full AMD gen with xbox and ps4 will be AMD's CPU+GPU.

So i guess valve' box on AMD hardware and linux OS will be soon a real gaming rig. <= I may be interested by valve' box. i just hope that games will be able to play @ PC fashion way. i don't like playing with other way than keyboard + mouse untill now. maybe they're going to improve way to do that with new ideas introduced by nintendo with wii, microsoft and google's glaces.

... if i can't choice what i can use to control my games, i'm not going to buy it for sure.

Rated and observed dont often match up, let alone given the method used to find observed or rated numbers (PS/VS, etc).

Gaming throughput of a full G71 GPU is about 165 gflops. In Physics only work its about 250. Rated total is nearer 400, for a fully enabled GPU. The RSX is more like a GT version.

Each VS pipe in G70/71 outputs 10 FP32 op's, while each PS pipe rates at 16 FP32 op's. A full configuration of 8xVS and 24xPS GPU in PS3 performs 464 FP32 op's per cycle, for grand total of 255 GFLOPs at 550MHz.

G70/71 was over slow ... and low number of units :/ Even when it comes out, ... So i was surprised they used cell and a low GPU for P$3.


It was a big mistake to not get a powerfull GPU instead of doing a CPU powerfull for the day when it comes and useless for gaming, hard to code and we all know a slow CPU is not a big problem if you have a powerfull gpu. But i'm sad they don't use 7970/7950 instead of 7850/7870, now 7870 is not so slow but in 4 years, it's gonna be very slow, and 7970 would be a be higher priced at start but go fast cheap and better for having some AA in game.

So PC is still the best ...

go 7970 for a good performance / price ratio and forget ps$4

Yup, but people like the bigger number given by FP16 that is not limited by register performance

Not too big of a compromise, I suppose. 7850 is capable of 153.6 GB/s, dual channel DDR3-1600 is capable of 25.6 GB/s; not too far from 174 GB/s promised by PS4. Still nothing impressive...

You're trolling right? because this console isn't using DDR3. AMD designed the memory controller that gave the 7850 153.6 GB/s, so why cant they implement this into this custom core?

Also people mentioning the geforce GTX 480 & 580....well the Ati 7870 is basically a match for these GPU's in graphics tasks (not so sure about GPGPU). So its no surprise. Seems quite good really.

[zalbard]

You're trolling right?

No, you just can't read. Nowhere I said PS4 was using DDR3. Desktop analogues do.

[dairyFarmer]

Yes, but the point isnt that the desktop proc.s only have 1/7th of the discreet cards bandwidth, but that they compromise very little in sharing between the cpu&gpu in actual use. You claimed there was a large compromise.

[behrouz]

Again, everything i've read says that's not the case. The "Reality Synthesizer" is the PS3's actual GPU, not to be confused with the Cell processor.

http://en.wikipedia.org/wiki/RSX_%27...Synthesizer%27

Btw... does anyone else find it odd that this claim of 1.8tflops seems to be higher than the GTX 580 Fermi

both 580 and 680 are listed here: C:\Users\Desktop\Downloads\Documents\GeForce-GTX-680-Whitepaper-FINAL.pdf
It just doesn't seem very likey that the graphics portion of what is essentially a mobile APU has the ability to beat out a discrete card that still costs about $400

maybe you mean this ? Geforce GTX 680 Whitepaper FINAL

What is the point of this comparison?

According to Table in www.planet3dnow.de :

Cinebench 11.5 single : Tamash = 0.35 , Trinity = 0.35
Cinebench 11.5 multith : Tamash = 1,39 , Trinity = 1.14
since Tamash works at 5w TDP while Trinity at 100w , this is really impressive.so Jaguar uses some of tech from Tamash ?

[informal]

Jaguar is the x86 core inside Kabini/Temash. Kabini and Temash are just codenames for SOCs(system on a chip containing CPU,GPU,IMC and rest of the logic).

[Tenknics]

GCN GPU inside PS4 is 1.84TFlops. How much did the previous NV based GPU have in PS3? If I'd had to guess it was something like 4-5 times less.

edit: Found it. G70 was 176 Gflops so more than 10 times slower. There is no comparison,not to mention PS4's GCN based GPU is supporting GPGPU .

You're speaking pure theoretical numbers. I'm talking about the look of actual games, you completely missed my point like many others.

Improvements in visual fidelity between generations is becoming less and less noticeable and in turn less of a marketable bullet point. Doesn't matter how many flops it pushes.
