Radeon HD 6950 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6950 comes with a core clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.Compare those specifications 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 along with 88 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)
Texel Rate
Both cards have exactly the same texel rate, so theoretically they should be equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at full screen anti-aliasing, and be capable of handling 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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability 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
