Radeon R7 370 2G vs Radeon R9 M265X

Intro

Compare all that to the Radeon R9 M265X, which uses a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Radeon R9 M265X		23000 Mtexels/sec
	Difference: 39400 (171%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 370 2G is a better choice, by far. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 22000 (239%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
