Radeon R7 370 4G vs Radeon R9 270X

Intro

The Radeon R7 370 4G comes with a GPU core speed of 975 MHz, and the 4096 MB of GDDR5 memory runs at 1400 MHz through a 256-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon R9 270X, which features core clock speeds of 1000 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs as well as 80 TAUs and 32 Rasterization Operator 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 perform exactly the same. (explain)

Texel Rate

The Radeon R9 270X is much (more or less 28%) more effective at anisotropic filtering 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 a better choice, 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
