Radeon R9 290X and R9 290 specifications are leaking online

At GPU Tech 2014, AMD introduced a new generation of graphics cards in the Radeon series, but without going into details. Instead, a battle stream leaks have revealed most about the new graphics cards, though with a few important exceptions. More knowledge gaps are now being sealed when Japanese Hermitage Akihabara publishes the specifications for the Radeon R9 290 and 290X performance models.

As previously reported, the flagship Radeon R9 290X contains as many as 2,816 stream processors up to 1.0 GHz, close to 40 percent more computing devices than its predecessor Radeon HD 7970. This includes 4 GB of GDDR5 memory in 5.0 GHz on a 512-bit memory bus , which provides a bandwidth of 320 gigabytes per second.

The scaled-down sibling Radeon R9 290 stops at 2,560 stream processors at up to 947 MHz, yet still with the same lavish memory configuration. Both newcomers are connected to PCI Express 3.0 with power supply via 6 + 8-pin connectors and support DirectX 11.2, OpenGL 4.3, True Audio and Mantle.

AMD has not announced a price or launch date, but the Radeon R9 290X is already available to pre-book in packages with Battlefield 4. The retailer Webhallen states that the preliminary delivery date is 11 October.
