Radeon HD 6950 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6950 comes with clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.Compare that to the Radeon HD 6950 2GB, which has GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also is comprised of 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so in theory they should be equally good at at AA, 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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max 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
