SAPPHIRE was the first in the world with a Radeon R9 290X with 8GB of VRAM, with its Vapor-X model but now it's back with another model, the Tri-X card. The new card features SAPPHIRE's great triple fan cooler, increased clocks, and dual BIOS.
We have 2816 stream processing units on the SAPPHIRE Radeon R9 290X Tri-X 8GB, with an engine clock of 1020MHz. 8GB of GDDR5 is spread across a 512-bit memory bus, clocked at 1375MHz (5.5GHz effective). SAPPHIRE has used its original PCB, with a 6-phase power design pushing upwards of 240W, with two 8-pin PCIe power connectors which provide up to 375W of total power.
SAPPHIRE is pushing this card out to its usual e-tailers and retailers, but we've reached out to the company and requested a sample already. So expected a review from us in the very near future.
