AMD started Radeon HD 6990 sales 8 March 2011 at a recommended price of $699. This is TeraScale 3 architecture desktop card based on 40 nm manufacturing process and primarily aimed at gamers. 2 GB of GDDR5 memory clocked at 5 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 160.0 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 295 mm. Two 8-pin power connectors are required, and power consumption is at 375 Watt.

It provides poor gaming and benchmark performance at


of a leader's which is NVIDIA GeForce RTX 3090 Ti.

  • Passmark
  • 3DMark Fire Strike Graphics


This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
