Chipworks Confirms Xbox One SoC Has 14 CUs with 2 Disabled
 

In our mini-review of the Xbox One I speculated that the shipping version of Microsoft's console featured 14 AMD GCN CUs (Graphics Core Next Compute Units), with two disabled to improve yields. Microsoft publicly stated that Xbox One development kits featured 14 CUs and Sony similarly had 20 CUs with only 18 enabled with the PS4. With Xbox One hardware in the wild, Chipworks went to task delayering the SoC/APU and confirmed the speculation - the Xbox One does indeed feature 14 CUs (pictured above).
