Radeon HD 6950 vs Radeon HD 6950 2GB
Intro
The Radeon HD 6950 features a clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 ROPs.Compare all of that to the Radeon HD 6950 2GB, which comes with 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 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so theoretically they should be equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel rate, so in theory they should perform 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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 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 speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the 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
