PS4.5 could theoretically play PS3 games in native 4K with better visuals and superior FPS.

GTX 580 is Vram starved guys.

No idea how it handles Shadow of Mordor then on settings that recommend 3GB Vram.

One game.... genius..... Come to think of it why have you not shown or talked about modern games on your system?

Try running The Vanishing Of Ethan Carter on that GPU at PS4 settings and it'll tank...lmao

I don't buy everything that releases. shadow of Mordor is a GPU heavy game and is a XONE/ PS4 title that asks for 3GB Vram, why are you not questioning me on that?

I don't think even high end PCs could emulate ps3.

Taken from Anandtech review of Assassins Creed Unity.

"Finally, I mentioned how 2GB GPUs are really going to have problems, especially at higher texture quality settings. The GeForce GTX 770 is a prime example of this; even at 1080p High, minimum frame rates are consistently dropping into the low teens and occasionally even single digits, and Medium quality still has very poor minimum frame rates. Interestingly, at 1600x900 Medium the minimum FPS basically triples compared to 1080p Medium, so if the game is using more than 2GB VRAM at 1080p Medium it's not by much."

You have less memory then 2Gb too!!! You would have to run the game at lower settings then PS4 to get it playable...... god bless that VRAM limitation....

And why you cherry picking one game.... I can link you to more reviews that show VRAM limited GTX580 if you wish...

The 580 is an old ass card.

I would love to test loads of games but somehow i don't buy every game, oh right i'm not a walking money tree, plus all the 2GB GPU's mentioned are running way less memory bandwidth lol.

So the only PS3 game above ( Battle Fantasia ) you show runs at a MASSIVE 16fps!! Wow... that's sure close to 4k and higher frame rates then PS3......lmao

Are you intentionally trying to make yourself look like an idiot...lmao

GTX970... heck even the GTX680 has less bandwidth and is faster then a GTX580.... you literally have no clue do you?

I know IQ is not a common thing around these parts.

Someone said he don't think even high end PC can emulate it, so i posted 2 vids, what has that got to do with the thread title? it's just me answering an off topic post, plus learn what theoretical means.

@scatteh316:

You also have to factor in CPU power as well, a GTX 580 with a modern intel quad core will still give PS4 a run for the money. Also that the PS4 suffers from DX11 limitations as well, with multiplats. If devs code beyond GNMX(copy paste high level API) then we will see the PS4 pull ahead.

But with well coded multiplats for example BF.

i7 920 at 3.6ghz with a GTX 580 1.5gb can play Battlefront with High settings at 1920x1200 with 50 fps average.... and with ultra settings 45 fps average. Most of the efficiency consoles see is on the cpu side of the code. Which means if you can brute force through the cpu overhead on pc console efficiency does not mean much.

No really you are the one not understanding memory.

Yes they are faster in GPU power, GPU is not the same as memory.

The 1.5GB 580 is suitably matched, and the 3GB 580's were never able to use the Vram, it required them to be in SLi to even utilize so much Vram.

Higher resolutions need more GPU power, so 580's would need to be in SLi.

You totally don't understand anything do you? keep building your PC's and upgrading and wasting cash, makes no difference to others.

Won't ever work for PS3 games because of the cell architecture, the emulator would never be that efficient at getting PS3 games to run straight up on a PS4 GPU. It might barely get them so that easy backwards compatibility is an option, but running them at 4K? LOLNO.

Perhaps some of the most optimized PC games from that era could run at 4K if somebody were willing to also port and optimize them to PS4 (i.e. throw out the PS3 port, and go back to the PC port as the basis for getting a 4K game on PS4K... that might be possible). But that is assuming "4K gaming" is going to be a thing at all on the PS4K. I'm still not convinced of that, think it will be more about streaming and movies.

I thought the 680 was gimped compared to the 580. I loved my 580, it was a beast of a card.

Still is for a 6 year old GPU, i'm waiting for Pascal and moving to a 5820K.

PS4 doesn't have any of the DX11 API fall backs that PC has because it's not a PC.... we've been over this a 1000x already in this forum.

Dude.... please... you're killing yourself...

But lets get back on topic..... PS45 could never play PS3 games in 4k at higher frame rates

/thread

If it uses Dx11 then sir, YES IT DOES.

Problem with that statement that GTX 580 3gb couldnt use the vram... It can, especially if the game allocates and stores as much as it can into the buffer. Now the question then becomes is the GTX 580 is strong enough to fully able to handle properly optimized game assets that require 3gb of buffer..... depends on how graphically complex the game is.

I was thinking of attaching them to a rocket. It's more more humane :P

That's different, BF3 would store everything it could into VRAM but only really needing 1GB even maxed at 1080P.

lol, with multiplats most devs do a copy paste job of DX 11 coding standards ie deferred multithreading on both the X1 & PS4. This means that consoles suffer from same cpu limitations as PC with DX11....

Like I said it depends how graphically complex and optimized the game is.

But PS4 doesn't use DirectX 11.....DirectX 11 requires a user agreement which Sony don't have... it uses Sony's own API......Again this topic on API's has been talked about 1000x already on this forum...... Once again proving you know nothing.

with multiplats most devs do a copy paste job of DX 11 coding standards ie deferred multithreading on both the X1 & PS4. X1's older API was a modified version of DX11 ie DX11.X it suffered from same cpu limits as DX11.... Then devs use Sony's GNMX and its ability to copy and paste other API usage without having to code from the ground up with GNM.

This means that consoles suffer from same cpu limitations as PC with DX11.... This is why we see GTX 750ti with strong dual core cpu able to compete with PS4 with multiplats.

With the release of DX12 on X1 this will allow the PS4 not to be limited by DX11 standards.

I dunno, those 4k shots in the OP don't look anything special.

The PS4 could already play PS3 games through a paid subscription PSNow. The technology is already there. As for discs, Sony could but they won't because they know they can get anyway with milking their consumers by remasters and more subscriptions. I think they're going to get pressured in offering BC but it's going to be fun seeing their users flip flop on their anti-BC stance.

I wouldn't be too surprised if the old 580 kept up pretty well with the ps4 in The Vanishing Of Ethan Carter.

Here's a benchmark at 1080p. The 580 could very well be able to get a pretty stable locked 30 fps. Sure the ps4 frame rate is a bit higher but is the ps4 version comparable to "very high quality".

WTF? NVIDIA Fermi was smashed in the recent FarCry Primal PC benchmark.

PS4 has CPU issues.

Just to add, XBO's support for DX12 SM6(AMD's wavefront programming model expose to DX programmer) will further improve PS4 ports.

PS4's "DirectX 11" support. This is to make game ports easy. Sony can rename Microsoft's APIs and change parameter order, but the programming model remains similar.

PS4 also has APIs similar to Mantle or DirectX 12.

PS4 is effectively "Xbox" with 18 CU GPU without Microsoft logo and Xbox Live services.

In theory you can make pigs fly.
