Radeon R7 300-series
AMD also refreshed the rest of its graphics card line, bumping its more mainstream GPUs up to the R7 300 and R9 300 series, all of which are compatible with the forthcoming DirectX 12 and Vulkan APIs—though few other technical details were revealed.
Kicking things off were the lower-end R7 offerings, which AMD says are tailor-made for playing e-sports games like Dota 2 and League of Legends at 1080p resolution.
These graphics cards support the Virtual Super Resolution technology—which lets GPUs render games at a higher resolution, then downsample it to your display’s output for better clarity—that first appeared in AMD’s Catalyst Omega driver last January. To ease the load on these modestly powered GPUs, they include a technology AMD calls “Frame rate target control,” which caps the GPU’s frame rate output in games where you get extremely high frame rates, in order to reduce power and noise needs. It sounds an awful lot like the “Dynamic frame rate control feature” AMD teased late last year.
Radeon R9 300-series
AMD also introduced a trio of more powerful Radeon R9 300-series graphics cards.
The $199 Radeon R9 380 was designed for 1440p gaming, AMD says, and packs up to 4GB of memory. Meanwhile, the $329 Radeon R9 390 and $429 Radeon R9 390X each pack 8GB of RAM, presumably for a better gaming experience at 4K resolution.
