Radeon R7 250X 2GB vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which has a core clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R9 M375X should be a bit (about 2%) more effective at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 600 (2%)

Pixel Rate

The Radeon R9 M375X should be just a bit (about 2%) more effective at AA than the Radeon R7 250X 2GB, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 240 (2%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
