Radeon HD 6950 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6950 comes with core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon HD 6950 2GB, which features core speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)
Texel Rate
Both cards have exactly the same texel rate, so in theory they should perform equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel fill rate, so theoretically they should be equally good at at full screen anti-aliasing, and be able to handle the same screen resolutions. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

1 fps isnt much of a difference.
Remember that 2gb -version can be modded into 6970 so then it is much faster than 6950. 🙂
hahaha it's obvious this site is soooo pro nvidia!!!!
because these benchmarks are pure bullsh*t!!! you go on other sites and you clearly see the 6950 is better on these games except for dirt 2 the 560ti does ~2 fps better than the 560ti
so this is really bullsh*t!

This is a load of CRAP!!!
I Own both cards & 6950 is way better in performance than 560ti PLUS you can also bios hack 6950 into a 6970.
Compare it with a 570 will rather be a very different Story.
ati is the best >> 😀 >
ati 6950 2gb faster than card of 1gp i have 1gp lol hhh xd >>>:D
2gb is faster ,when the resolution is higher
bf3 use 1.5 gb videomemory---->
with 1gb version lagging the game with higher res

HWCompare has created a site that is based on half-truths, skewed data / cherry-picked data and misinformation. Benchmarks are false measures of true performance. These cards will NOT behave the same performance (as this HWC page wrongly concludes) in real world scenarios. The 1GB version will bottleneck at high-resolutions, while the 6950 2GB will be able to easily buffer more graphical data without raw (fps) performance degradation.
EDIT previous post: should read, "without the same level of raw (fps) performance degradation." ;P
