ATI Radeon HD 5670 640SP Edition Image ATI Juniper Image
The Radeon HD 5670 640SP Edition was a mid-range graphics card by ATI, launched in July 2010. Built on the 40 nm process, and based on the Juniper graphics processor, in its Juniper LE variant, the card supports DirectX 11.0. The Juniper graphics processor is an average sized chip with a die area of 166 mm² and 1,040 million transistors. Unlike the fully unlocked Radeon HD 5770 X2, which uses the same GPU but has all 800 shaders enabled, ATI has disabled some shading units on the Radeon HD 5670 640SP Edition to reach the product's target shader count. It features 640 shading units, 32 texture mapping units and 8 ROPs. ATI has placed 512 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 750 MHz, memory is running at 1000 MHz.
