The Radeon R7 450 OEM was a graphics card by AMD, launched on June 30th, 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. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. 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 paired 2,048 MB GDDR5 memory with the Radeon R7 450 OEM, 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 (4.5 Gbps effective).
Being a single-slot card, the AMD Radeon R7 450 OEM draws power from 1x 6-pin power connector, 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.
