Performance Rating
The Radeon R9 390 X2 was an enthusiast-class graphics card by AMD, launched on September 3rd, 2015. Built on the 28 nm process, and based on the Grenada graphics processor, in its Grenada PRO variant, the card supports DirectX 12. This ensures that all modern games will run on Radeon R9 390 X2. The Grenada graphics processor is a large chip with a die area of 438 mm² and 6,200 million transistors. Unlike the fully unlocked Radeon R9 390X, which uses the same GPU but has all 2816 shaders enabled, AMD has disabled some shading units on the Radeon R9 390 X2 to reach the product's target shader count. Radeon R9 390 X2 combines two graphics processors to increase performance. It features 2560 shading units, 160 texture mapping units, and 64 ROPs, per GPU. AMD has paired 16 GB GDDR5 memory with the Radeon R9 390 X2, which are connected using a 512-bit memory interface per GPU (each GPU manages 8,192 MB). The GPU is operating at a frequency of 1000 MHz, memory is running at 1350 MHz (5.4 Gbps effective).
