In exclusive we have the detailed first specs (not final) for PS4, most likely first alpha kits sent to developers:
TLDR SPECS
CPU
- 4 core (2 core pairs) 3.2 GHz AMD x86 (Steamroller)
- aggregate, 10x PS3 PPU performance
- 512 KByte L2 per core pair
- 64 bit pointers
GPU
- AMD R10x series GPU @ 800 MHz (Tahiti)
- aggregate 10x RSX performance, 1.84 TFlops
- DX”11.5″
- cheap branching
- 18 compute units, focus on fine grained compute & tessellation
MEMORY:
- 2 GByte UMA, pushing for 4 GByte
- 192 GByte/ sec non-coherent access for e.g. GPU
- 12 GByte/ sec coherent access for CPU
- >50% longer memory latency for CPU/ GPU compared to PC!!!
- DXT is lowest bpp texture compression format
MEDIA:
- 50 GByte BD drive
- PCAV, between 3.3 and 8x BD, most likely clamped to 6x
- automatic background caching to HDD
- HDD SKU with at least 380 GByte
- downloadable games
EXTRA HARDWARE:
- video encoder/ decoder
- audio processing unit, ~200 concurrent MP3 streams
- HW zlib decompressor
Our source claims that the final specs should be 10x powerful than PS3, due to this info has got 10 months.
