AMD Pitcairn Specifications Surface

Stefan Mileschin · 21st February 2012, 06:42

The launch of AMD's Radeon 7800 series is on course for March, as AMD wants to complete the launches of the entire Radeon 7000 series before NVIDIA even has its first GPU out. Radeon HD 7800 will be designed to occupy key price points in the sub-$300 market segment, where it strikes price-performance sweetspots for gamers. Central to this series is a new 28 nm GPU, codenamed "Pitcairn", from which will be derived three SKUs: the Radeon HD 7870, Radeon HD 7850 2 GB, and Radeon HD 7850 1 GB. The specifications look like this:

Radeon HD 7850

20 Graphics CoreNext Compute Units, 1280 stream processors
80 TMUs, 24 ROPs (de-linked from the memory bus, of course)
256-bit wide GDDR5 memory interface, 2 GB and 1 GB variants
Clock speeds of 900 MHz core, 1250 MHz (5.00 GHz effective) memory

Radeon HD 7870 specifications follow.
