AMD R9 300 / Fury serien Recensioner ETC

Enligt Anandtech så är prestanda per klockfrekvens förbättrad något på 300-serien, så till skillnad ifrån vad folk tror finns det förbättringar under huven.

"Last but certainly not least however, we want to talk a bit more about the performance optimizations AMD has been working on for the 390 series. While we’re still tracking down more details on just what changes AMD has made, AMD had told us that there are a number of small changes from the 290 series to the 390 series that should improve performance by several percent on a clock-for-clock, apples-to-apples basis. That means along with the 20% memory clockspeed increase and 5% GPU clockspeed increase, we should see further performance improvements from these lower-level changes, which is also why we can’t just overclock a 290X and call it a 390X.

So what are those changes? From our discussions with AMD, we have been told that the clock-for-clock performance gains comes from a multitude of small factors, things the company has learned from and been able to optimize for over the last 2 years. AMD did not name all of those factors, but there were a couple of optimizations in particular that were pointed out.

The first optimization is that AMD has gone back and refined their process for identifying the operating voltages of Hawaii chips, with the net outcome being that Hawaii voltages should be down a hair, reducing power and/or thermal throttling. The second optimization mentioned is that the 4Gb GDDR5 chips being used offer better timings than the 2Gb chips, which can depending on the timings improve various aspects of memory performance. Most likely AMD has reinvested these timing gains into improving the memory clockspeeds, but until we get our hands on a 390X card we won’t know for sure."

Tänk ändå så jävla bra rebrands är, vi som sitter med äldre kort som har "rebrandats", vet att AMD kommer att ge våra drivrutiner samma kärlek som de nya kortens får.

XFX Radeon R9 390 Review

Hoppas att folk slutar rekommendera R7 370 snart. Det kostar lika mycket som R9 380 men är betydligt långsammare.

Fury x quad fire vs 980ti quad sli vs titan x quad sli

edit: pcper skriver så här vilket jag fann intressant angående fury x

But what about that direct AMD and NVIDIA comparisons? Despite what we might have expected going in, the AMD Radeon R9 Fury X actually scaled in CrossFire better than the NVIDIA GeForce GTX 980 Ti. This comes not only in terms of average frame rate increases, but also in lower frame time variances that result in a smoother gaming experience. In several cases the extra scalability demonstrated by the Fury X allowed its dual-GPU performance to surpass a pair of GTX 980 Ti cards even though in a single GPU configuration the GeForce card was the winner. GRID 2 at 4K is one example of this result as is Bioshock Infinite at 4K. And even in a game like Crysis 3 at 4K where we saw NVIDIA's card scale by a fantastic 84%, AMD's Fury X card scaled by 95%!
