Compare any two graphics cards:

Radeon R7 M360 vs Radeon R9 M390X

Intro

The Radeon R7 M360 comes with a clock speed of 1125 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon R9 M390X, which comes with a core clock frequency of 723 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Radeon R7 M360		16000 MB/sec
	Difference: 144000 (900%)

Texel Rate

The Radeon R9 M390X should be much (more or less 243%) more effective at AF than the Radeon R7 M360. (explain)

Radeon R9 M390X		92544 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 65544 (243%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the Radeon R7 M360, by a large margin. (explain)

Radeon R9 M390X		23136 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 14136 (157%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 figure is calculated by multiplying the total amount of texture units of the card 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 amount 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 amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
