AMD's drivers are absolute garbage and not worth dealing with.

Plus, at the end of the day, Nvidia really does make better cards.

AMD's a good budget option, but their stuff costs less for a reason.

Better image quality? Visionary features? Wut.

Kepler GK110 still has garbage GpGPU performance and still lacking DirectX11.1 Level 11.1 support.

Non-Microsoft Direct3D GPGPU face-off: K20 vs 7970 vs GTX680 vs M2050 vs GTX580 from http://wili.cc/blog/gpgpu-faceoff.html

K20 = GK110

There's very difference between NVIDIA's OpenCL and CUDA.

PS, Sony PS4 would not be using Microsoft's Direct3D stack.

App 1. Digital Hydraulics code is all about basic floating point arithmetics, both algebraic and transcendental. No dynamic branching, very little memory traffic.

App 2. Ambient Occlusion code is a very mixed load of floating point and integer arithmetics, dynamic branching, texture sampling and memory access. Despite the memory traffic, this is a very compute intensive kernel.

App 3. Running Sum code, in contrast to the above, is memory intensive. It shuffles data through at a high rate, not doing much calculations on it. It relies heavily on the on-chip L1 cache, though, so it's not a raw memory bandwidth test.

App 4. Geometry Sampling code is texture sampling intensive. It sweeps through geometry data in "waves", and stresses samplers, texture caches, and memory equally. It also has a high register usage and thus low occupancy.

I don't think Sony would be repeating yet another GpGPU challenged solution.

1st party PS4 games would have an extreme AMD Gaming Evolved results.

I expected more from GK110's 551 mm^2 die size and ~$1000 price tag.

Having "King Tiger" tanks doesn't win the war.

8800 GTX has very little effect against Wii, Xbox 360 and PS3. Intel Haswell GT3 will shutdown NVIDIA's low end PC parts (upto Geforce 650).

Qualcomm is strong enough to constrain Tegra 4 (single design win from ZTE).

[QUOTE="BlbecekBobecek"]

 

Yeah but its the best data we have for comparison. It is to be expected that the PS4 GPU will be further optimised to provide even better results than standard PC architecture.

RyviusARC

Optimization won't help it.

Most of the API overhead on PC is from the CPU not the GPU.

So GPU performance from console to PC with similar GPU specs will be pretty much equal.

The only people I hear say this are pc gamers, Yet the people that actually develope the game say the opposite.  I think I would take the word of the people that actually make the games.  A PC with the same GPU isnt going to hold a candle to a console, it never has and it never will. 

So how does this compare with my I920, 6 gigs of GDDR3 and a GTX285?

Yah it's a monster compared to the PS3.

I am happy they went all out and also added more RAM.

Now PC won't be held back as much.

Can't wait for the Maxwell series of Nvidia GPUs next year.

I am predicting another 8800GTX.

nameless12345

I'm expecting it once GDDR6 hits the market

and they'll need to invest in some high end PC exclusive to take advantage of it like they did with Crysis

Will it happen this time, tho?

CryTek clearly said that developing just for PC is not worth it and Epic are like minded as well...

The future of high budget "AAA" games is multi-platform and (most likely) console-centric development.

If you're refering to the typical blockbuster 5 hour long game than sure, but plenty of AAA devs on PC and some potential ones, but what exactly are talking about in budgets and AAA? Ironic epic games is developing a PC exclusive but I have a feeling that it might get ported to consoles later considering these new specs.

Star Citizen and RSI seem like the number 1 PC game and developer to challenge PS4 and Xbox 720

Ronvalencia is having a goddamn field-day.

[QUOTE="Chozofication"]

Why are people talk about emulating the PS4?  Today's PC's can't even emulate 360.  People must have no idea how emulation works on here...

nameless12345

True.

The first Xbox was literally a PC in console case yet emulating it was not an easy task...

Also, you would need atleast 10-times better PC to emulate it so good luck with that...

 

The only people I hear say this are pc gamers, Yet the people that actually develope the game say the opposite.  I think I would take the word of the people that actually make the games.  A PC with the same GPU isnt going to hold a candle to a console, it never has and it never will. 

AM-Gamer

Instead of taking my word or anyone else look up the facts.

If you look at gameplay performance and compare an 8600gt to a 360 you will see they perform similar with the 8600gt sometimes having the edge.

The 8600gt is similar in power to consoles.

If what you think were true the 360 should be smashing the 8600gt and yet it isn't.

On the other hand you need a more powerful CPU than the 360's to get similar performance.

This is because of the API overhead.

Yes!

Its more powerful than:

GeForce GTX 480 (1.34 TFLOPS)

GeForce GTX 580 (1.58 TFLOPS)

 

Its almost equal to:

GeForce GTX 660 (1.9 TFLOPS)

 

Its less powerful than:

http://www.nordichardware.com/Graphics/geforce-gtx-660-for-oems-appears-on-nvidias-website.html

-------------------------------

So as we can see its quite a bit more powerful than what was considered bleeding edge in 2011 and only the latest and most expensive and powerfull current GPUs gain considerable edge over it.

Noone has ever optimised a game for such powerful hardware. We have not yet seen how a game optimised for it might look. Forget Crysis 3 on ultra settings - games that the new PS4 shall bring us will wipe floor with it. Crysis 3 on ultra runs just fine on the less powerful GTX 580 afterall, and that is even further slowed down through API.

you can compare TFLOPS between AMD gpus and nvidia gpus

HD7850: 1.76 TFLOPS, Engine Clock 860Mhz, 16 Compute Units (1024 Stream Processors), 64 Texture Units , 2/4GB GDDR5 with 153.6GB/s memory bandwidth

PS4 GPU: 1.84 TFLOPS, Engine Clock 800Mhz, 18 Compute Units (1154 Stream Processors), 72 Texture Units , 8GB GDDR5 with 176.0GB/s memory bandwidth (shared with CPU)

HD7870: 2.56 TFLOPS, Engine Clock 1000Mhz, 20 Compute Units (1280 Stream Processors) , 80 Texture Units , 2/4GB GDDR5 with 153.6GB/s memory bandwidth

HD7950: 3.05 TFLOPS, Engine Clock 850Mhz, 28 Compute Units (1792 Stream Processors) , 112 Texture Units , 3GB GDDR5 with 240.0GB/s memory bandwidth

HD7970: 4.10 TFLOPS, Engine Clock 1000Mhz, 32 Compute Units (2048 Stream Processors) , 128 Texture Units , 3/6GB GDDR5 with 288.0GB/s memory bandwidth

as you can see the ps4 GPU is very similar to the HD7850 and it is a barely a mid range GPU and by the time ps4 will be released will be low end GPU.

its a good GPU.  Very similiar performance off the shelf to a 7850 in terms of raw TFLOPS comparison.  Its GCN architecture based though, so more efficiency and better Compute performance than that architecture provides.

 

The bigger thing is 8Gb of RAM.  Its a absolutel godsend that Sony upped that from the rumored 4gb.  It will have a larger effect on PS3 games then pretty much everything else.

Its pretty high end if you ask me. Saying its "barely mid-range" is downplaying it a lot. Its about 5x more powerful than my GeForce GT 555m and I can run every single PC game on medium - high and most of them even on ultra (for example Im running DotA 2 maxed out on 1080p resolution, Crysis 2 on highest settings on 720p resolution with AA off, etc).

I mean - my laptop runs all of the games hermits rave about on these boards on highest or near-highest settings and thats with GPU that has fractio of PS4's GPU power, and its still crippled by API overhead. The point is that whatever the graphics of PS4 will look like is still only a matter of imagination since we have not seen such graphics yet.

no it is not

HD7950 & HD7970 are high end(for single gpu), and the HD7850 & HD7870 are mid range and also all these models are already one year old.

Essentially when the ps4 will be released will have a gpu that it was mid range 2 years ago.

How ? On PC you have to account for the swaping of ram to Vram, if a game is based on the unified architecture and optimized for zero swaps, how do you emulate that fast ram with no swaps ?

One variable you totally forgot... Sony is said to only target 14CU of the 18CU for the gaming while the other 4CU will be used for the lcd controller gpgpu workloads, physics etc. Which means the gpu will normally will never match a 7850 performance. 14CU=1.4 TFLOP. Also you totally have the idea of that guy who made FXAA wrong.... his statement was talking about improving texture fetching improvement not the whole gpu's performance, they can not bypass the hardware's physical processing limitations. Also you totally ignored basic computer functions The PS4 will never use 6 or 8gb for video usage, You have to account OS all the features, game data load and then video load into the memory.

Also the PS4 OS and all the features stated will use alot more then 512mb... you will be looking at 2gb OS+features, game will use 4gb(no streaming data) and video use 2gb since anything over 2gb is pointless at 1080.. Also your example of the 7850 vs 7950 is off you should only look at Direct x 11 based games since that will be the new set standard, The 7950 at 1080+ is still much faster then the 7850. Also you should look at dirt3 minimum fps too that gives you the real difference in base line performance.But lets not forget the 7950 boost clock performance or even the 7970 or even crossfire or SLI into the mix by the end of the year the 7850 will be considered mid ranged at best. Heck AMD APU's are going to get igp's nearly as fast as a 7750.
