PS4 specs compared to PC

[johndud]

Can someone tell me how the PS4 specs compare to PC's now, I read this article that was so vague it just said the games look good. Here is the article in question with specs.

dunno if anyone else actually watched the conference, but they did mention that they are using an APU not a seperate CPU and GPU, and that is why they can use a single type of ram being GDDR5 to output the "best" performance. also seeing as they are finally doing away with the cell processor and going with mainstream x86 maybe we will see better ports to PC and possibly over to the new xbox if they too decide to go the route of x86, which would not suprise me.

the leap in power compared to last gen's comparison is not as huge, but its still a big jump in resourses, im going to expect very good things in gaming this generation since it seems console developers are finally being thought of to simplify their development on more familiar architecture.

more info on the PS4 GPU, and comparison with other AMD 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

Until someone does a full test on the thing we are pretty much just guessing.
The PS4 will be very optimized and as such that means that it will outperform its bare specs.
What we need to know is what high-end GPU features will it be capable of and which of these features will actually be made use of by game developers.

Its going to look nice and run smooth but can it do teh high res textures that a true gaming PC can ?

hahaha the 8 GB GDDR5 is the RAM... ^^

*facepalm*
Atleast read a few posts on this thread itself. 8 GB is not the RAM. It's unified memory. Used for both RAM and Graphics
That's why,

8GB GDDR5 with 176.0GB/s memory bandwidth (shared with CPU)

8 GB of Unified System Memory would mean memory available for processing + rendering is equal to 8 GB.
Or, it can also be 8GB GDDR5 of Graphics Memory + X GB DDRX of RAM.
Or, it uses the Memory used as RAM is nothing but the Graphics RAM it self. [:O. It's possible?]

But the word is, that the PlayStation 4 indeed uses GDDR5 Memory as the System RAM.

As for the Graphics Processing Power, the

GTX 580 has 1581.1 Gigaflops
GTX 590 has 2488.3 Gigaflops

GTX 660 has 1881.6 Gigaflops
GTX 670 has 2459.5 Gigaflops
GTX 680 has 3090.4 Gigaflops

PS 4 has 1843.2 Gigaflops

So again, a new gaming PC will beat the PS 4 in Graphics Processing [don't know about how PS4 will use the 8 GB Memory it has, but 680 has 4 GB GDDR5, and 690 has 2*4 GB GDDR5].

Even if the PS 4 has 8 GB DDR5 exclusive RAM, and considering the fact that GDDR 5 architecture is based on DDR3 SDRAM memory, 16 GB of DDR3 RAM on a PC will be pretty close [Not exactly perhaps, I do not know. GDDR5 is supposedly a huge boost].

Edit:
Just now found that 8GB of unified memory is being used. So, it's... "the Memory used as RAM is nothing but the Graphics RAM it self". Or may be the other-way round, which ever way you like to call it.

Thanks,

8GB of unified memory will be shared between GPU,CPU and OS.So probably OS with all this multi-tasking etc. would consume max of 2gb,gpu takes 2gb and they will have 4gb ram at disposal.Its a huge leap over current gen consoles. And its also developer-friendly(at least for PS4).
But still i dont think it will match the 2005/06 consoles when they were on par with highest most expensive pc hardware.PC-s have already minimum of 2-3gb gpu,8gb ram so like that has been told,launch game would be on par with crysis 3 graphics.
Although developers can develop games "hardware to the metal" for consoles and optimizing,also this would mean even a year after graphics would go from very high-high, few years low-medium.
Not impressed with games like killzone,destiny ,looks like pre-rendered sh*t.But still will be huge leap forward. It would be nice to know most important thing,if they manage to make analog sticks more precise...?is it even possible to do that?

LOL it has already been said that Killzone was real time, ANd it looks like Pre-renderd shit to U. You bet your ass you should be impressed now.

It was cool when Ubisoft said that the gameplay demo of Far Cry 3 was actual game footage, and it was even cooler when Aliens: Colonial Marines advertised target renders as real-time gameplay.

Perhaps you'll forgive us mere mortals for not being able to suspend our disbelief. You bet your ass that you're welcome to think and buy whatever you like though. No one could or should try to stop you.

Consoles don't have an OS like PCs

just in case you dont know, a32bit cpu cant compare to a x64...... so yea a pc should always outpremorm a console
