On April 5, AMD will release its newest Radeon HD 6000 series GPU, which
it has been largely secretive about. The new Radeon HD 6790 is designed
to compete with NVIDIA's GeForce GTX 550 Ti. The HD 6790 is based on
AMD's 40 nm "Barts" GPU (on which are based HD 6850 and HD 6870). The
Barts silicon is configured to have 800 stream processors (SPs)...hang
on, unlike the 800 SPs on Juniper (HD 5700 series, HD 6770), the 800 SPs
(arranged in 10 streaming multiprocessor units) on Barts will be
spread across two blocks of 400 SPs each, each block having its own
dispatch processor. Also unlike Juniper, Barts LE (HD 6790) will have 32
ROPs, 40 TMUs, and a 256-bit wide GDDR5 memory interface. The core will
be clocked at a generous 840 MHz, and 1050 MHz (4.20 GHz effective)
memory, churning out 134.5 GB/s memory bandwidth. The GPU is expected to
have TDP of under 150W, and will draw power from two 6-pin power
connectors.
