| Trumpstyle said: Yes I believe so too. Except I'm getting more positive towards the Navi gpu. I think the radeon 680 will beat the 1080 ti from Nvidia and have similiar performance to geforce 2080. Ps5/xbox two gpus will probably beat the geforce 1080 ti by about 10-20% :). So a bit higher than a high end pc. |
Navi had better beat the Geforce 1080Ti, a GPU derived from Pascal which is already a few years old at this point.
| Random_Matt said: GCN can only accomodate 64CU's, custom would be too expensive. Loving the TF numbers people are throwing about. PS5 will not be a massive leap, the pro proved that. |
That is 64CU's per chip. You can have more than one chip working together.
As for the Playstation 4 Pro... The majority of it's power went to enhancing framerates/resolution, so of course the leap will seem to be rather mediocre.
| Trumpstyle said: 7nm gives about 3x transistor in same die size compared to 16nm in ps4 pro. |
Source?
| Chazore said: So AMD is going to totally crush Nvidia in one fell swoop along with PS5?. |
nVidia will answer with Volta.
AMD is so far behind in the GPU game it's pretty terrible.
Hopefully they can turn things around with their next gen GPU uArch.

That would mean 112 GB of RAM in the PS5!! Now, this gen we saw a jump of ~15.5x. That would mean 124 GB of RAM in the PS5!!! Max we are seeing in the PS5 is 32GB, which is only a 4x jump. However, that extra 24GB of RAM would truly be bigger than the extra 7.5GB we got this gen. |
PS1: 3.5Mb of Ram total. (2MB system, 1MB video, 512kb Audio.)
PS2: 40-42MB. (32MB System, 4MB video, 2MB Audio, 2-4MB I/O.)
PS3: 512MB. (256MB System, 256MB video.)
PS4: 8448. (8192MB System, 256MB Background tasks.)
PS4 Pro: 9216MB. (8192 System, 1024MB Background tasks.)
The jump from PS1 to PS2 was in-fact 11.4x -12x
The jump from PS2 to PS3 was 12.8x - 12.19x
The jump from PS3 to PS4 was 16.5x.
The jump from PS3 to PS4 Pro was 18x.
But the real caveat is "Usable Ram". - This generation saw probably one of the largest increases in Ram consumption not reserved for gaming.
5.5GB is available on the Playstation 4 for instance... With the OS gobbling up 2.5-3GB
Whilst on the Playstation 3 the OS was only 50MB.
Ergo...
Playstation 4: 5,632MB for games.
Playstation 3: 462MB for games.
Meaning there was a 12.19x increase in DRAM for developers with the jump from the PS3 to PS4, putting it inline with historical increase trends.
With that in mind... GDDR6 is allowing for a doubling of DRAM density over GDDR5.
And the highest density GDDR5 is 8 Gb chips... Where-as the Playstation 4 has 16x 4 Gb density chips.
So by 2020 it could be economical to have 32GB of GDDR6, prices at the moment is crazy though.
