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. 

Good summary and commentary. Even without the console specific optimizations, this thing is less capable than a PS4 because of the lack of low level API access. Open GL simply cannot compete with custom APIs. However, if XB1 had the raw power of this machine, then the playing field would be even.

Also for games created for PC on Open GL, the Steambox can still perform better than a PS4 in certain circumstances, especially given the reduced bloat and optimized drivers for the Steambox and SteamOS
