This all makes me think that Kinect is a great tragedy. As an Xbox One owner I find it neat and useful, but not $100 useful. IIRC the tear downs said the BoM was likely in the $75 range. For an extra $75 in silicon they could have built a much more powerful machine. Possibly even enough to run their launch titles in native 1080p at 60fps.That would be great for consoles and for driving improvements in PC games. Absent a killer app for Kinect it sure seems like the wrong compromise. We'll get some great improvements nonetheless, but there could always be more.
Yes, they could have easily matched the PS4. However, I doubt it would have been a lot more powerful than PS4. The timing when MS and Sony decided to release their systems coincides with major issues of 20nm node at both TSMC and GloFo. Going beyond 1152-1280 Shaders on AMD side would have entailed using the much more expensive and power hungry 28nm Tahiti Pro. Considering that GPU by itself uses ~ 145-160W, that's not really an option.
The GPU inside PS4 is more or less a Wimbledon XT (7970M, announced May 1, 2012) with 2 CUs disabled and slightly lower GPU clock (800 vs. 850mhz).
1 year later - May 5, 2013 - the successor 8970M was just a rebadged 7970M with a 50Mhz GPU boost, or barely a 6% increase in performance.
Nearly 2 years later since 7970M launched, on January 7, 2014, M290X because just a rebrand of the HD 8970M with identical performance. This means that from May 1, 2012 to today, AMD's flagship mobile performance in the 100W TDP improved just 6%! :thumbsdown:
Therefore, even if MS waited until August 20, 2014 to launch XB1, with AMD at best they could have gone with a full 1280 SP M290X @ 900mhz clocks which is barely better than PS4's 1152 SPs @ 800mhz. If they had done this, PS4 would have had 15+ million sales then. And if MS had gone with a full blown M290X, yields would have been lower.
If MS really wanted to beat PS4 in performance they should have taken a Core i3 or a downclocked voltage optimized FX8320/FX6300 and paired it with an 870M but that would have meant major delays to late 2014 which would have given PS4 an even larger head start. The timing of PS4/XB1 made it extremely difficult to make those consoles much faster on the GPU side. Hopefully PS4/XB1 get replaced in 5-6 years (2018-2019) and we won't have to wait until 2021-2022. :biggrin:
