The results we're seeing, at 8MP, would appear to indicate that Fury has enough colour fillrate, since that resolution is the most likely to tax colour fillrate.May be AMD should have gone with more pixel throughput for Fiji this time. There's still leftover BW for that to burn in.
Isn't Fury writing more than its theoretical 67 gigapixels per second in this test?Looks like Fiji's frame-buffer compression is only a bit better than Kepler's:

Now I revise my suggestion -- AMD should have put a more aggressive colour compression instead.![]()
All I know is that it actually leverages hardware PRT/Tiled resources. On console I assume they would make use of asynchronous copy and with directX 12 being released next month on PC they should be porting that over to some degree.Were there details given about Doom 4?
Tom's shows that it is not quiet:
Something is not right about this review!
Nobel Prize to the person who noticed same thing as me!
HBM @600MHz?!? Overclocked in CCC !?! How??
I've not had direct involvement with consumer graphics of over a year now.
I think we will find drafting errors in most reviews due to time constraints. In some cases it will be obvious and others not.![]()
well its been known for a week or so that there wouldn't be voltage adjustments at launch.
http://arstechnica.com/gadgets/2015...k-performance-but-doesnt-beat-980-ti-overall/The results over at Tom's Hardware are something of an anomaly compared to those of other sites, though. Hexus' results showed the Fury X as slower than the 980 Ti in most games at 1440p and 4K, which was echoed by the benchmarks over at Maximum PC and Tech Report.
To discern a real difference between the Fury X and 980 Ti, you need to look at numbers other than average frame rates—and then AMD's offering starts to sag. First off, there's overclocking performance, which isn't great. PC World noted in its review that, despite AMD touting the Fury X as "an overclocker's dream," it was only able to eke out an extra 50MHz on top of the stock 1050MHz clock speed before instability set in. Hexus did slightly better with a 90MHz overclock, but no site managed anything particularly ground breaking. Memory overclocking isn't possible, either, due to AMD locking it down at a hardware level. Notably, a factory overclocked 980 Ti consistently out performed the Fury X in PC World's benchmarks.
The biggest differentiator, though, is power consumption and heat. Traditionally, AMD hasn't fared too well, but the Fury X does far better. The combination of more power-efficient HBM memory and an excellent watercooling system has enabled AMD to keep the GPU temperature down to around an impressive 60 degrees Celsius under load, far cooler than the 80C-and-higher of the stock Nvidia cards. AMD says the Fury X consumes around 275 watts under load on average, and the reviews largely reflect that, showing peaks of around 290 watts. That's still on average around 40 watts more than 980 Ti, and around the same as a 290X, but it's an impressive showing considering the extra performance on offer.
For all the good AMD has done with the Fury X, there's still one niggle that cropped up in most reviews: a high frame time variance. This is a problem that has long afflicted AMD cards, causing stuttering slowdowns, despite an overall high average frame rate.
