Well, that didn't take long, PC gets GDDR5 system RAM support

[QUOTE="no-scope-AK47"]

Thats not memory for the CPU though ;). And it has already been proven in this thread the PS4 GPU is the most powerful not even available on the market for hermaps to buy.MstaPrimeMnista

1. hard drive slowest

2. ddr3

3. cpu very fast till cache gets full goes to ddr 3 then to the hard drive

4. gpu fastest till ddr5 fills up then goes to ddr3 almost never happens..

In this chain you can add a ssd that will take the hard drives place and/or use two hard drive in raid 0. This eliminates the bottle neck of the hard drive. You can also add more ddr3 as well and make a ram disc that will act like fast virtual hard drive. This way the cpu just goes to the ddr3/ssd that is much faster than the hard drive. The gpu uses it's gddr5 and the cpu basically talks directly to the gpu over the 384bit bus giving instructions on what the gpu needs to do. So the ddr3 is mostly for the cpu. Okay hermits don't jump and down I know I left out alot of info.

the problem with MstaPrimeMnista is that he is misinterpreting what this Link says.  He thinks they are saying that the apu is the strongest graphical hardware on the planet, when that is not anywhere near what they are saying.  what amd has stated is that the apu in th ps4 is just that, the strongest apu to date, out of all the apus they use in laptops.  he is literally confusing himself thinking they are saying that that apu is stronger than dedicated gpu's.  hes completely mixing it all up and hes literally confused himself to the point of believing that which is false.

[QUOTE="Rage010101"]

[QUOTE="no-scope-AK47"] The hd 7970 came out in 2011 and it smokes the gpu in the ps4 and you can buy one on ebay for 350 to 300 bucks. As for how ddr3 is used in your pc basically it is like this.

1. hard drive slowest

2. ddr3

3. cpu very fast till cache gets full goes to ddr 3 then to the hard drive

4. gpu fastest till ddr5 fills up then goes to ddr3 almost never happens..

there are many dedicated gpu's that completely obliterate the ps4's "integrated" gpu.  looks like we figured out what is wrong here, you literally have no idea what an apu, gpu, and cpu are.

wow, I haven't seen so much talk about something with such significance since Sony announced the play station 3 with its cell processor.

Dark_man123

I am also looking forward to playing ps4 exclusives at 1080p 60 fps. This gen on console 720p was 30fps at best on most games. Often sub 720p on many games with unstable frame rate to be nice. At least my 1080p 3d 120hz hdtv will finally get used for more than blu-rays on console.

Yup and those will cost top dollar too. Kinda how like OLED Tv's are out and so are 4k, but no one except the super rich people will ever own one until the technology ages and drops down into what we like to call "affordable". And also that pretty much nothing on the PC is going to take advantage of that since Consoles dictate the market and again PC will mainly get ports.

It's gonna be a new line of CPU's that are going to cost a pretty penny, along with new mobo's and new gpu's. When you buy all this stuff right when it comes out, its all very expensive and will cost at least 2-3x as much as a PS4. 

And as far as being outdated goes...

Think that all you people who just build Core i7/AMD whatever's equivilent builds with DDR3 are now going to be outdated too. So not only will the consoles be updated, but all of us with PC's now will be too. 

The PS4 will do fine and PC will continually just run the same games in a higher resolution, but even then the gaps closing, 1080p is enough for a TV. My monitor is 1920 x 1200 and I have no plans to upgrade it until it dies. Plus, S-PVA 1920 x 1200 panel > Higher res TN panel.

It's mainly that Playstation fans are extreamly happy that the PS4 won't have the same weaknesses as the PS3, it's easy to develop for and has a large amound of fast ram for games, meaning open world games like Skyrim won't be such a problem anymore. Ports have no reason to be inferior as well. GDDR5 isn't magic, it just means that texture streaming will be vastly improved and like I said, there will be lots of it availiable and not only for games, but for running other things in the background too like downloads and such.

thanks for clarifying and confirming you have no idea what you are talking about :|

Mmm. Yes I'm very much looking forward to being able to build half-decent decent gaming PCs with an APU rather than CPU+GPU combo. I also like Crossfire with a GPU to the APU. Will change the landscape of entry level PC gaming. Hell, even the A8-3850 wasn't exactly 'bad'. 

psymon100

Funny you should mention that since I just built a little xfire htpc recently based around A8-3870K.:P

It's not a powerhouse, yet. Running A8-3870K+6570(oc'd) xfire, 4GB DDR3-1600, Senty 2420 case, Coolermaster GenimII M4 HSF, 360 wireless adapter.

Some games run really well on it. For instance, RE5, Crysis 1&2, Dirt Showdown, Torchlight.

Benchmark for RE5:

APU-only(oc'd 3.2GHz/800MHz CPU/GPU)   ~30fps medium settings, blur, 2xAA, 720p
6570   ~20fps all high settings, blur, 8xAA, 1080p
APU+GPU xfire   ~35fps all high settings, blur, 8xAA, 1080p

A game like Saints Row with DX11 effects will reduce it to single GPU performance. Chokes on 720p medium mix.

---

Weird sidenote is that oc'ing the APU in single mode helps significantly, but while in xfire appears to have no performance gain. 

I'm waiting for 7850(8850?) low pro next year at a decent price for my last upgrade to the system. It will fall between the 720 and PS4 in power and run full BC with all the Steam Sales and Humble Bundles in the world to look forward to. Steam Big Picture with 360 wireless controller on this puppy is a sight to behold. *PS3 phat was something like 12x3x10 inches Senty 2420 case is 12x4x15 inches.

Can't wait to see what Kaveri+7750(8750? lol!) can do. Xbox is pretty much beat to death on value by a setup like that if you don't care about Kinect.

LOL @ Cows, this is TEH CELL all over again :lol:

Yeah, I'm running the 7850, it's stonky. You know another great thing about such machines? Power consumption is low too. A ~430W Corsair with 80+ cert will do the job no problems (as long as there's sufficient amps on the 12V for any future GPU).

"nvidia beats them on the gpu front" is dependant on the benchmark mix and one expects the massive 551 mm^2 chip size Titan to win. Titan wouldn't win performance per area(chip size).

7970 has a chip size of 365 mm^2.

K20 = GK110 ~= Titan

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.

Not without some extra parts

No there isn't just 2 less computers units,don't look at peak teraflop performance,because the 7870 is highly inefficient compare to the PS4,in fact the difference between the 7870 and the 7850 is basically nothing.tormentos

In BF3, C2, and C3 it's ~13%. Crysis 3 will push it 15-20% depending on the AA variant. We've yet to see what the PS4 is capable of in multiplats. Still see it falling below the 7870 and above the 7850. We'll see in the first wave of games. KZ SF not looking so mindblowing in gunplay segments, could improve before launch? 

You're a PS fanatic, so I'd expect you to be fast to class it with 7970. I'll remain skeptical on the secret sauce until I see it put up against current cards by DF and other tech sites. Either way the 7950 still exists for only $50 more than the card I spec'd and that leaves us at $785 to beat PS4 7-months prior to it's launch. Working the other direction, it takes something as low as a 7850 2GB to match the PS4 in multiplats.

So is a $600-700 complete build with OS around PS4's launch a high-end PC? Does $700 usd beat the £1000 challenge I was addressing?

It's PC gaming what do you expect.

I'm not sure I get this. Isn't GDDR just video memory and in the case of the PS4 it's unified so it'll be used by the system too? Is this article talking about using GDDR5 as main memory (RAM, not VRAM)?

Your preaching to the wrong person bro. Nvidia makes the fastest single gpu right now it may not have the best price to performance ratio but it is the fastest. I will tell anybody looking to upgrade now get a 7970 on ebay for 300 bucks.

Having a massive 551 mm^2 chip size one CPU, one would expect NVIDIA's Titan to win.

Being the fastest is dependant on software and NVIDIA doesn't have control over next-gen console game development.

Remember, having "King Tiger" (aka Tiger II) tank doesn't win the war i.e. Geforce 8800 GTX's 480 mm^2 chip size didn't did not significantly impact Wii, Xbox 360 and PS3 sales.

-Unreal-

With Intel Xeon Phi, GDDR5 is not just video memory.

Intel Xeon Phi is a "many core" based X86 CPU with very wide 512bit SIMD (Larrabee) units.

AMD's own multi-core X86+GCN (wide very SIMD units) with GDDR5 based APU solution could to be use against Intel Xeon Phi.

DDR3 wouldn't be enough for AMD Kaveri APU's quad-core Streamroller CPUs and Radeon HD 7750 class (8 CUs @ ~900Mhz).
