Radeon R7 370 2G vs Radeon R9 270X

Intro

The Radeon R7 370 2G comes with a GPU core speed of 975 MHz, and the 2048 MB of GDDR5 memory runs at 1400 MHz through a 256-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon R9 270X, which has a core clock speed of 1000 MHz and a GDDR5 memory speed of 1400 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 2G 110 Watts
Radeon R9 270X 180 Watts
Difference: 70 Watts (64%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 270X should be quite a bit (about 28%) faster with regards to anisotropic filtering than the Radeon R7 370 2G. (explain)

Radeon R9 270X 80000 Mtexels/sec
Radeon R7 370 2G 62400 Mtexels/sec
Difference: 17600 (28%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 270X is superior to the Radeon R7 370 2G, but it probably won't make a huge difference. (explain)

Radeon R9 270X 32000 Mpixels/sec
Radeon R7 370 2G 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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
