Radeon HD 6950 2GB vs Radeon R7 370 2G

Intro

The Radeon HD 6950 2GB has a GPU core speed of 800 MHz, and the 2048 MB of GDDR5 memory is set to run at 1250 MHz through a 256-bit bus. It also is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Compare those specs to the Radeon R7 370 2G, which has core clock speeds of 975 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Texel Rate

The Radeon HD 6950 2GB should be a bit (approximately 13%) more effective at texture filtering than the Radeon R7 370 2G. (explain)

Radeon HD 6950 2GB 70400 Mtexels/sec
Radeon R7 370 2G 62400 Mtexels/sec
Difference: 8000 (13%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 370 2G is superior to the Radeon HD 6950 2GB, and very much so. (explain)

Radeon R7 370 2G 31200 Mpixels/sec
Radeon HD 6950 2GB 25600 Mpixels/sec
Difference: 5600 (22%)

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 moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
