Radeon R7 250X vs Radeon R9 M370X

Intro

Compare those specs to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 250X is much (about 25%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon R7 250X		40000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 8000 (25%)

Pixel Rate

The Radeon R7 250X will be quite a bit (about 25%) faster with regards to AA than the Radeon R9 M370X, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R7 250X		16000 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 3200 (25%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type 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 can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of 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 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 reach the maximum fill rate.
