AMD Radeon R7 450 OEM Photo AMD Cape Verde Photo
The Radeon R7 450 OEM is a graphics card by AMD, launched in June 2016. Built on the 28 nm process, and based on the Cape Verde graphics processor, in its Cape Verde PRX variant, the card supports DirectX 12.0. The Cape Verde graphics processor is an average sized chip with a die area of 123 mm² and 1,500 million transistors. Unlike the fully unlocked Radeon HD 7770 GHz Edition, which uses the same GPU but has all 640 shaders enabled, AMD has disabled some shading units on the Radeon R7 450 OEM to reach the product's target shader count. It features 512 shading units, 32 texture mapping units and 16 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 925 MHz, memory is running at 1125 MHz.
Being a dual-slot card, the AMD Radeon R7 450 OEM draws power from 1x 6-pin power connectors, with power draw rated at 65 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon R7 450 OEM is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
