PlayStation 4K to Feature a 2,304-SP AMD "Polaris" GPU

Sony's upcoming 4K Ultra HD game console, which its fans are referring to as the "PlayStation 4K," while being internally referred to by Sony as "NEO," could feature a very powerful GPU. AMD could custom-design the SoC that drives the console, to feature an 8-core 64-bit x86 CPU based on the "Jaguar" micro-architecture, running at 2.10 GHz; and a GPU component featuring 36 compute units based on "next-generation Graphics CoreNext" architecture.

36 next-gen GCN compute units sounds an awful lot like the specs of the Polaris10 "Ellesmere" chip in its Radeon R9 480 configuration, working out to a stream processor count of 2,304 - double that of the 1,152 on the current-gen PlayStation 4. The SoC is also rumored to feature a 256-bit GDDR5 memory interface holding 8 GB of memory. This memory will be used as both system and video memory, just like on the current-gen PlayStation 4. The memory bandwidth will be increased to 218 GB/s from the current 176 GB/s. Besides 4K Ultra HD gaming, this chip could also prepare Sony for VR headsets, leveraging AMD's LiquidVR tech.

That was two years ago and two weeks after he left id Software to join Oculus. I have doubts that he said it from experience. Some one at DICE, Unity, or Epic would be a better source.

So 25-28 fps is 'just fine', which happens only in ideal situations? The game can dip to the lower 20's... The whole point was, Fallout 4 does *not* meet its target render times at all. It fluctuates like a motherf. and it does that on a highly regular basis. It is constantly sluggish. It is constantly struggling. It performs worse than FO3 did on the PS3.

And it is not the first game either that suffers from this, nor is it new to the PS4. What is new with the PS4, is that we get a serious GPU boost now while the CPU remains a slow POS. The PS3 was clearly gpu limited, the PS4.5 will be cpu limited.

So does this mean that console ports might actually run better on our PCs? /s :rolleyes: A man can dream right. :laugh:

Well I wouldn't play Dark souls III on 1080/30Fps on my PC, even my old GTX 780 runs perfectly at 1440p/60FPs/LOW and looks better, but I find my self strangely forced to play Bloodbourne at what I can describe as unplayable stutter at 10-30Fps on my PS4, definitely not 60fps. Probably the worst computer-related part I ever had. Nothing is optimized, CPU is still bottle necking . This newPS4 Its like running R290 paired with 1GHz I3-6100 or something like that.

Why would just 'someone' from Unity have more credibility than Carmack?

I'm afraid not.
But with x1.3+ CPU and x2.3+ GPU power, Sony exclusives will be nothing short of amazing. (check what they did on PS3 with The Last of Us)

I guess you missed the whole part where they updated the game and the framerate problem almost entirely went away. The parts where it dipped to 20FPS were patched in version 1.02 and now the game holds a steady 30FPS almost always.

Ironically, the game now runs better on the PS4(which has the stronger GPU) than on the XBO(which has the stronger CPU). The game is pretty clearly GPU bound.

Quite a few people have already come out and said the PS4K will scale 4K gameplay from 1080P. The people complaining about the jaguar GPU are also out of their minds if they think that is holding the console back. This is a console which means games are written for it. This is not a PC were games are ported to it.

Also jaguar is not FX based. It has 8 real cores not 4 modules and 8 threads. Basically this will go from having dual athlon 5150's to having dual athlon 5350's. Which in CPU loaded benchmarks my own personal Athlon 5350's @2.3 beat out the A6-7400K@4.6ghz.

I will definitely be selling by XB1 for this. I would be perfectly happy with 1080p in high action games and 30 fps in 4k with adventure games. Equally important, I will be needing a 4k Bluray player, and this will work great.
This should have 3x the bandwith of the XB1 and 3.5x the fill rate. This a nice jump in performance. Gamecube to WII was less than double. XB360 to XB1 was around a 5x increase in fill rate, but only a 3x increase in bandwidth.... and that was 8 years later!

I have been very unimpressed with the XB1. The dashboard is such a damn mess. I often get glitches with Netflix and certain games like BF have been glitchy as hell with matchmaking.

How so? It is similiar to the expansin pack for the N64. You don't need to use the extra hardware and it is easy to scale down with the same architecture. In fact, this will probably be more appreciated by some developers, because they can upscale certain older games as well.

GhostRyderYou know, saw this coming a mile away. While it's cool to have new consoles, it's annoying to have to upgrade/switch again (even if they keep both at the same time) so soon. The consoles were made at an awkward time and should have waited a bit longer or opted for some alternative solution to get more performance.

Oh well, cannot wait to see it!
The timing wasn't good. PS3 and X360 were at their limit yet the next big thing (4k) wasn't mature enough, waiting would have been worse. Even though the update comes 3-4 years later, in the 16-32 bit era the consoles lasted about 5 years, it's not that bad.

True, but were going from buying a console to last 7+ years of service back to below 5 years. Not to mention both consoles in their first year were off to a slow start and games were so few and far between that it took them awhile to truly get going. I just hope this is a worthy upgrade and the next batch last awhile.

The first year of PSX was quite poor too, until 1996/1997 the really good games didn't begin to come. Revisions always happened, the PSX had a major revision with the PSone in 2000 while it was launched in 1994/1995, there was also a revision of the Mega Drive in 1993 while it was launched originally around 1989. The PSP has been the most revisited console, it had about 5 major revisions in the spawn of 6-7 years.

Frankly, having 4k and better speeds overall it's a good upgrade, if they can also reduce the footprint it would be perfect.

Ironic, that what PS4k is really about is 1080p. That's the minimal resolution devs should aim for. :)
