VS

Radeon HD 5970 vs Radeon R9 M290X

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 along with 160 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon R9 M290X, which comes with GPU core speed of 850 MHz, and 4096 MB of GDDR5 memory set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X 100 Watts
Radeon HD 5970 294 Watts
Difference: 194 Watts (194%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be 67% quicker than the Radeon R9 M290X in general, due to its greater data rate. (explain)

Radeon HD 5970 256000 MB/sec
Radeon R9 M290X 153600 MB/sec
Difference: 102400 (67%)

Texel Rate

The Radeon HD 5970 is a lot (more or less 241%) more effective at texture filtering than the Radeon R9 M290X. (explain)

Radeon HD 5970 232000 Mtexels/sec
Radeon R9 M290X 68000 Mtexels/sec
Difference: 164000 (241%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5970 is the winner, by far. (explain)

Radeon HD 5970 92800 Mpixels/sec
Radeon R9 M290X 27200 Mpixels/sec
Difference: 65600 (241%)

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 data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
