AMD Readies 4 GB Variant of the Radeon R9 390

In a bid to step up the pressure on NVIDIA's GeForce GTX 970 and the product-stack below it, AMD is getting its add-in board (AIB) graphics card partners to launch cost-effective variants of the Radeon R9 390, with 4 GB of memory, instead of the 8 GB that was standard to the SKU. These cards feature 4 GB of memory across the chip's 512-bit wide GDDR5 memory interface, and could help AMD and its partners shave a few dozen Dollars off the standard version, which is currently selling for as low as $309.

4 GB of memory would make the R9 390 a complete re-brand of the R9 290, if not for its clock speeds. The custom-design variants of the 4 GB R9 390 ship with clock speeds that are 10% higher than those of the R9 290, and the performance was found to be proportionately higher, by Expreview. Of the three cards spotted crawling their way out of product launch pipes in China, the ones from XFX and PowerColor retain the design and packaging of their 8 GB siblings; while Sapphire mated the chip with a new dual-fan cooler with a meaty, split aluminium fin-stack heatsink.
