Doom to use async compute

[CAT-THE-FIFTH]

In GPU space AMD and ATI before them always developed very forward leaning products but they've also struggled immensely to get the balance right and capitalise on it - often jumping the gun to their own detriment. This time around it is something that they could really work to their advantage as the architecture has great synergy with the nature of nodes sub 20nm planar and DX12 and similar APIs.

Regarding Kepler though - outside of maybe the witcher 3 which I've never played - I'm not really seeing Kepler falling behind (that isn't to say it couldn't be running better than it is if they were spending more time on optimising it but that isn't something I can qualify) - a lot of benchmarks if you dig into it you'll find they are either using old Kepler numbers and not actually retested older cards when they say they have, using numbers given to them by AMD or nVidia or testing Kepler cards limited to the reference on paper clocks - the numbers you see are often anything upto 20% (though normally more like 10-15%) lower than what users will be experiencing in the real world. (Before you add in any end user overclocking).

Kepler is falling behind though since everyone only looks at the GTX780 series cards and not any of the others ones. My GTX660 is now consistently much slower than an HD7870 when they were quite closely matched at launch,and the rest of the range really didn't overclock anywhere as well in percentage terms as the GTX780. One of the reasons the review sites had to change their testing methodology(and I was talking with someone who knew a reviewer) was because Boost V1 tended to have issues over longer time periods,ie,throttling,which a few German and French websites discovered and it made the results look higher than they did.

Then you add certain review sites,ie, like pcgameshardware which use pre-overclocked cards in their benchmarks and even a highly overclocked GTX770 is not doing as well. Even a pre-overclocked GTX770 running at 1.2GHZ clockspeed is loosing to stock clockspeed R9 280X in The Division:

The R9 280 and R9 280X had very minimal boost,ie,around 50MHZ and these cards could hit 1.2GHZ which meant they could easily bypass an overclocked GTX770 in the game.

An overclocked GTX670 is slower than an overclocked HD7870 in the game too.
