Radeon HD 5970 vs Radeon R9 M375

Intro

The Radeon HD 5970 comes with a GPU clock speed of 725 MHz, and the 1024 MB of GDDR5 RAM runs at 1000 MHz through a 256-bit bus. It also is made up of 1600 SPUs, 160 TAUs, and 64 ROPs.

Compare those specs to the Radeon R9 M375, which has core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

The Radeon HD 5970 is quite a bit (more or less 471%) more effective at texture filtering than the Radeon R9 M375. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon R9 M375 40600 Mtexels/sec
Difference: 191400 (471%)

Pixel Rate

The Radeon HD 5970 will be much (approximately 471%) faster with regards to AA than the Radeon R9 M375, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon R9 M375 16240 Mpixels/sec
Difference: 76560 (471%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 ability to reach the maximum fill rate.
