Radeon R7 M360 vs Radeon R9 M390X

Intro

The Radeon R7 M360 comes with a GPU core speed of 1125 MHz, and the 2048 MB of DDR3 RAM runs at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Compare all of that to the Radeon R9 M390X, which comes with core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

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

Texel Rate

The Radeon R9 M390X is a lot (about 243%) faster with regards to texture filtering 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 far. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
