Thats quite the jump then really for the GPU if true. The only issue is, the small bump rumoured for PS4K CPU is going to be an even bigger bottleneck this time round no?
Not really. The CPU bottleneck depends on the resolution. The higher the resolution, the more GPU power is used, hence the lower bottleneck the CPU can produce. So in 1080p the difference may not be big against the current PS4, but in 4K the difference will be outrageous.
So Neo will run a low clocked version of the RX 480 :)
Thats still pretty good news.
Very low clocked. By the specs, the 480 is going to have around 5.5TFlops and it's performance should be a little over the 390.
If rumors are to be considered, the PS4Neo has 4.something TFlops, but that's the whole system, not only the GPU. So basically the GPU is cut down in half. Talk about a low clocked version!
