Today AMD has launched their new AMD Radeon HD 6900 Series. The new graphics cards are based on a reworked GPU core called "Cayman" that features a new shader design called VLIW4. Read our HD 6950 Review to get an idea about the architectural changes and find out how the single card performs. This review will investigate how two HD 6950 cards in CrossFire perform, whether HD 6950 CrossFire is a viable solution considering price/performance and to also shed some light on what to expect from a future AMD HD 6990.

With Cayman and the HD 6970, AMD is introducing its biggest design change for the GPU's SIMD processing area since Radeon HD 2900 series, it's also introducing a greater amount of parallelism to the graphics engine, and doubling the standard memory amount from 1 GB in the previous generation Radeon HD 5870 and Radeon HD 5850, to 2 GB on both Radeon HD 6970 and HD 6950. resulting in 4 GB of memory for the HD 6950 CrossFire setup reviewed here. As a brief lesson on AMD's naming scheme with this generation, Radeon HD 6950 and HD 6970 represent high-end single GPU SKUs, successors to HD 5800 series, while the recently introduced HD 6800 series are in a segment of their own with no definitive predecessors.

Benchmark scores in other reviews are only comparable when this exact same configuration is used.
  • All video card results were obtained on this exact system with the exact same configuration.
  • All games were set to their highest quality setting
Each benchmark was tested at the following settings and resolution:
  • 1024 x 768, No Anti-aliasing. This is a standard resolution without demanding display settings.
  • 1280 x 1024, 2x Anti-aliasing. Common resolution for most smaller flatscreens today (17" - 19"). A bit of eye candy turned on in the drivers.
  • 1680 x 1050, 4x Anti-aliasing. Most common widescreen resolution on larger displays (19" - 22"). Very good looking driver graphics settings.
  • 1920 x 1200, 4x Anti-aliasing. Typical widescreen resolution for large displays (22" - 26"). Very good looking driver graphics settings.
  • 2560 x 1600, 4x Anti-aliasing. Highest possible resolution for commonly available displays (30"). Very good looking driver graphics settings.

Aliens vs. Predator


Aliens vs. Predator is based on a merger of the Aliens and the Predators franchise: two legendary alien species that are in conflict with each other, fighting to the death with human marines caught in between. The first person shooter game was developed by Rebellion Studios, who also developed the first AVP PC title and released in February 2010. It was one of the first DirectX 11 games with support for new features like Tesselation, which is why AMD heavily promoted it at the time of their DX 11 card launches. We used the AVP benchmark utility with tesselation and advanced DX11 shadows enabled.
