The new AMD R9 390 is the direct successor to the R9 290. Both cards share the same GPU but the R9 390 is factory overclocked. The R9 390 has a 5% higher stock GPU clock, and a substantial stock memory clock increase of 20%. Additionally the R9 390 sports a minimum of 8GB of VRAM versus 4GB on the R9 290. At the current price levels of $329, the R9 390 can't compete given that R9 290s can be had for around $260. The increased VRAM will rarely help even at ultra high resolutions and in any case, most 4K gamers are likely to seek more GPU power than the R9 390 has to offer. We have seen several samples of the R9 390 and they scored an effective speed of 88.5% which, as expected, matches the speeds seen on overclocked R9 290s. On the face of it purchasing an R9 290 at a discount and then manually overclocking will result in the same performance as an R9 390 but with a saving of around $70. [Jun '15GPUPro]
Launched in 2010 on the 40Nm process, these Radeon mobile graphics are basic by today's standard - better than some integrated units of the last few years but any current processor will demolish it. It features 400 shaders, 20 texture units and 8 ROPs as well as 1GB of DDR3 on a 128-bit bus. TDP is 26W with clocks of 650 and 800MHz for core and memory.
I got an overall score of 6.17% for mine in a Lenovo Ideapad, with the latest drivers and an overclock to 900MHz core and 1000MHz memory. In real terms this made running older titles like 'Fallout 3' a lot more pleasant, with smoother frames and much less detectable input lag.
Overall? Comparatively terrible, but very acceptable if you're the owner of a cheap, used laptop! [Jul '19boingk]
