The latest video cards have been launched by AMD in an attempt to spoil the NVIDIA GeForce GTX 560 Ti launch. These include the Radeon Radeon HD 6950 1GB and the Radeon HD 6870. The Radeon 6950 1 GB has 1408 unified shaders, 88 texture units, 32 Render Output Units (ROP), and a core clock of 800 MHz. It comes with 1 GB of GDDR5 memory on a 256-bit memory bus running at 1.25 GHz.

The price for the card is expected to be $259, which you can find on this

, which is very similar to the price for the NVIDIA GeForce GTX 560 Ti. Anandtech has posted a new review of the AMD Radeon HD 6950 1GB video card.

In practice the 1GB 6950 is just as fast as the 2GB 6950 at 1920×1200 and 1680×1050 – the essential resolutions for a $260 card. It’s only at 2560×1600 and Eyefinity resolutions that the 2GB card makes a difference with most games at this time. This is likely to change in the near future, but for the time being –and as you’ll see – there’s little disadvantage to a 1GB 6950 right now.
