Radeon R7 370 2G vs Radeon R9 M290X

Intro

The Radeon R7 370 2G features a GPU core clock speed of 975 MHz, and the 2048 MB of GDDR5 memory is set to run at 1400 MHz through a 256-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

Compare that to the Radeon R9 M290X, which has a core clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M290X 100 Watts
Radeon R7 370 2G 110 Watts
Difference: 10 Watts (10%)

Memory Bandwidth

In theory, the Radeon R7 370 2G should perform just a bit faster than the Radeon R9 M290X overall. (explain)

Radeon R7 370 2G 179200 MB/sec
Radeon R9 M290X 153600 MB/sec
Difference: 25600 (17%)

Texel Rate

The Radeon R9 M290X is a small bit (about 9%) faster with regards to texture filtering than the Radeon R7 370 2G. (explain)

Radeon R9 M290X 68000 Mtexels/sec
Radeon R7 370 2G 62400 Mtexels/sec
Difference: 5600 (9%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 2G is a better choice, but not by far. (explain)

Radeon R7 370 2G 31200 Mpixels/sec
Radeon R9 M290X 27200 Mpixels/sec
Difference: 4000 (15%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
