Radeon HD 6950 2GB vs Radeon R9 M395X

Intro

The Radeon HD 6950 2GB comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Compare those specs to the Radeon R9 M395X, which comes with core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M395X 125 Watts
Radeon HD 6950 2GB 200 Watts
Difference: 75 Watts (60%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R9 M395X should be a lot (more or less 31%) faster with regards to anisotropic filtering than the Radeon HD 6950 2GB. (explain)

Radeon R9 M395X 92544 Mtexels/sec
Radeon HD 6950 2GB 70400 Mtexels/sec
Difference: 22144 (31%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 6950 2GB is superior to the Radeon R9 M395X, though only just barely. (explain)

Radeon HD 6950 2GB 25600 Mpixels/sec
Radeon R9 M395X 23136 Mpixels/sec
Difference: 2464 (11%)

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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
