Radeon HD 5970 vs Radeon R9 M375

Intro

The Radeon HD 5970 has clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1600 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all of that to the Radeon R9 M375, which features GPU core speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5970 should in theory be quite a bit superior to the Radeon R9 M375 in general. (explain)

Radeon HD 5970 256000 MB/sec
Radeon R9 M375 35200 MB/sec
Difference: 220800 (627%)

Texel Rate

The Radeon HD 5970 should be a lot (about 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 should be much (more or less 471%) more effective at FSAA than the Radeon R9 M375, and will be capable of handling higher screen resolutions better. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
