Radeon R7 250X 2GB vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific model. 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 in theory they should perform the same. (explain)

Texel Rate

The Radeon R7 250X 2GB is a little bit (about 8%) better at anisotropic 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

The Radeon R7 250X 2GB is a little bit (more or less 8%) better at AA than the Radeon R9 M365X, and also will be able to handle higher screen resolutions more effectively. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 fill 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 max fill rate.
