Radeon R7 370 2G vs Radeon R9 M290X

Intro

The Radeon R7 370 2G uses a 28 nm design. AMD has set the core speed at 975 MHz. The GDDR5 RAM works at a frequency of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

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

Radeon R9 M290X 153600 MB/sec
Difference: 25600 (17%)

Texel Rate

The Radeon R9 M290X should be just a bit (about 9%) better at AF 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

The Radeon R7 370 2G will be a small bit (about 15%) more effective at FSAA than the Radeon R9 M290X, and should be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
