Radeon R7 250X 2GB vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which uses a 28 nm design. AMD has set the core frequency at 925 MHz. The GDDR5 RAM works at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 250X 2GB should be a little bit (approximately 8%) better at texture filtering than the Radeon R9 M365X. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 3000 (8%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250X 2GB is superior to the Radeon R9 M365X, not by a very large margin though. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1200 (8%)

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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
