Performance Rating

The Radeon R9 390 was a performance-segment graphics card by AMD, launched on June 18th, 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. 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 to reach the product's target shader count. It features 2560 shading units, 160 texture mapping units, and 64 ROPs. AMD has paired 8 GB GDDR5 memory with the Radeon R9 390, which are connected using a 512-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 1500 MHz (6 Gbps effective).
