CHIP DESIGNER AMD has updated its Radeon R7 range of desktop graphics processors with the Radeon R7 250X and the Radeon R7 265 GPUs, the latter of which promises a 25 percent improvement in performance over other products in its class.
Available at the end of this month, AMD's latest two graphics processors join the previously released Radeon R7 240, R7 250, R7 260, and R7 260X, all of which feature the firm's Graphics Core Next (GCN) architecture, Crossfire multi-GPU technology, Eyefinity multi-monitor technology and the firm's Powertune overclocking tool.
The desktop graphics processor series has also been built using AMD's Mantle API for alleviating CPU bottlenecks such as API overhead or inefficient multi-threading. This allows systems with entry-level, midrange or otherwise modestly priced graphics processors to see improvements in graphics performance.
Along with Mantle, AMD's Radeon R7 series also integrates support for DirectX 11.2 and multi-display configurations on Ultra HD displays sustaining resolutions up to 3840x2160, including support for non-tiled 2160p60 displays.
The Radeon R7 265 is the highest performing of the series, delivering 2GB of default GDDR5 memory with a 256-bit memory bus. PCI-E 3.0 is also the standard for the R7 265.
The R7 250X is a sub-£100 GPU designed for HD 1080p gaming. As the successor to the Radeon HD 7770, it has 640 stream processors and can be clocked up to 1.0GHz with support for 128-bit GDDR5 memory configurations up to 2GB.
The new AMD Radeon R7 GPUs will be available at the end of this month from AMD partners Asus, Gigabyte, HIS, MSI, Powercolor, Sapphire and XFX. There's no UK pricing yet, but AMD said that the Radeon R7 265 will be available at a starting price equivalent to about £110.
With the introduction of the AMD Radeon R7 265, AMD is also adjusting the price of the AMD Radeon R7 260X, which will now be available starting at around £90.
Last month, AMD launched its long-awaited Mantle API through Catalyst 14.1 beta drivers and a Battlefield 4 update. µ
