Sorry I used the R9 270 X specs... now the real comparison.
| PS4's GPU | R9 270 | |
| CUs | 1152 | 1280 |
| TMUs | 72 | 80 |
| ROPs | 32 | 32 |
| ACEs | 8 | 2 |
| Queue | 64 | 2 |
| Clock | 800Mhz | 900Mhz |
| VRAM | 8GB Shared | 2GB |
| Bandwidth | 176.0 GB/s | 179.2 GB/s |
| TrueAudio | Yes | No |
| Architecture | GCN 1.1 | GCN 1.0 |
PS4's GPU runs at lower clock (100Mhz less) and have less processing units but it all compensate by the more "close to metal" programming where the R9 270 have a lot more overhead layers that put consoles optimizations ahead in terms of performance.
The difference in memory size is favorable to PS4 too and it is way more capable in Compute tasks than R9 270... so TrueAudio support and 8 ACEs.
Overall the PS4's GPU will performance way better than R9 270.
The Mantle can help to decrease the GAP but it is not available to StreamOS (Linux).
Conclusion: PS4 is stronger and $100 cheaper.
PS. I won't do a Xbone comparision because everybody here knows the result.
