The Guru of 3D published a review on the HIS Radeon R9-290X
A quote from the article:
In this review we test the HIS Radeon R9-290X. The product is based on the reference design of the original Radeon R9-290X. These cards are little beasts. As such this in-depth review will cover the Volcanic Islands GPU architecture, Hawaii for the 290 series, we'll benchmark these cards with FCAT Frametimes, Ultra High Definition and of course, we'll check out game performance with the latest games next to power consumption and heat levels as well. This is one review you don't wanna miss!HIS Radeon R9-290X Review @ Guru3D
Now before we begin with the new graphics cards, the first thing that you guys will need to get used to is the new naming schema. AMD ended with the Radeon HD 7000 and 8000 series graphics cards in 2013. Logic dictates that AMD would have continued with a series 9000. But hey now, we already have had the Radeon 9000 series many years ago (2003), oh and who doesn't remember the Radeon 9800 Pro right? As such it was time to bring in a new naming scheme, a bit more in line with AMD's APUs. R9 will be high-end and R7 will be mainstream and inevitably R5 being entry level. After that you'll notice products being tagged as 250, 260X, 270X, 280X and the coolest two of them all are the Radeon R9 290 and R290X.
