| HoloDust said: Few details calculated based on rumoured specs for PS4: Pixel fillrate: 25.6GP/s Texel fillrate: 57.6GT/s Memory clock: 1375MHz |
32 ROPs @ 800mhz = 25.6 pixel fillrate
18 Compute Units (GCN 1.0 is set up as 4 TMUs per 1 CU) or 72 TMUs @ 800mhz = 57.6 texel fillrate
Seems legit!
AMD also reiterated that GCN 1.0 / HD7900 will remain the fastest single GPU family for all 2013. That means GCN 2.0 is 100% ruled out for PS4/720 as that micro-architecture designation is likely slated for 20nm Volcanic Islands. HD8000 series aka Sea Islands is still based on respun GCN 1.0 HD7000 parts.
