Radeon R7 370 4G vs Radeon R9 270X

Intro

The Radeon R7 370 4G has core clock speeds of 975 MHz on the GPU, and 1400 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Compare that to the Radeon R9 270X, which comes with GPU clock speed of 1000 MHz, and 2048 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is made up of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Radeon R7 370 4G 110 Watts
Radeon R9 270X 180 Watts
Difference: 70 Watts (64%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon R9 270X should be quite a bit (more or less 28%) better at AF than the Radeon R7 370 4G. (explain)

Radeon R9 270X 80000 Mtexels/sec
Radeon R7 370 4G 62400 Mtexels/sec
Difference: 17600 (28%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 270X is the winner, though not by far. (explain)

Radeon R9 270X 32000 Mpixels/sec
Radeon R7 370 4G 31200 Mpixels/sec
Difference: 800 (3%)

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 max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
