OpenCL 1.2 Vulkan 1.2 Shader Model 5.1 Pitcairn GPU Notes Architecture Codename: Southern Islands The card measures 210 mm in length, and features a dual-slot cooling solution. Radeon HD 7850 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. Display outputs include: 1x DVI, 1x HDMI, 2x mini-DisplayPort. The GPU is operating at a frequency of 860 MHz, memory is running at 1200 MHz (4.8 Gbps effective).īeing a dual-slot card, the AMD Radeon HD 7850 draws power from 1x 6-pin power connector, with power draw rated at 130 W maximum. AMD has paired 2,048 MB GDDR5 memory with the Radeon HD 7850, which are connected using a 256-bit memory interface. It features 1024 shading units, 64 texture mapping units, and 32 ROPs. Unlike the fully unlocked Radeon HD 7870 GHz Edition, which uses the same GPU but has all 1280 shaders enabled, AMD has disabled some shading units on the Radeon HD 7850 to reach the product's target shader count. The Pitcairn graphics processor is an average sized chip with a die area of 212 mm² and 2,800 million transistors. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles.
AMD RADEON HD 7800 CUDA PRO
Built on the 28 nm process, and based on the Pitcairn graphics processor, in its Pitcairn PRO variant, the card supports DirectX 12. The Radeon HD 7850 was a performance-segment graphics card by AMD, launched on March 5th, 2012.
