Around all the buzz surrounding the Radeon R9 290X, we're ignoring its smaller, more affordable sibling, the Radeon R9 290 (non-X). It's being reported that the SKU will be formally launched on the 31st of October, 2013. From leaked AMD presentation slides, we know that the R9 290 is based on the same 28 nm "Hawaii" silicon as the R9 290X, but with a lower stream processor count, standing at 2,560, and a proportionately lower TMU count, at 160. The rest of the components on the chip are untouched, it still features a 512-bit wide GDDR5 memory interface, holding 4 GB of memory. The GPU core is clocked up to 946 MHz, and memory at 5.00 GHz, churning out 320 GB/s of memory bandwidth. The leak also highlighted the review NDA lifting time for the R9 290X, which is tomorrow.
