Radeon HD 7750 vs Radeon R9 M365X

Intro

The Radeon HD 7750 features a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon R9 M365X, which features a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R9 M365X is quite a bit (about 45%) faster with regards to anisotropic filtering than the Radeon HD 7750. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 7750 25600 Mtexels/sec
Difference: 11400 (45%)

Pixel Rate

The Radeon R9 M365X should be a small bit (approximately 16%) faster with regards to anti-aliasing than the Radeon HD 7750, and able to handle higher resolutions more effectively. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 7750 12800 Mpixels/sec
Difference: 2000 (16%)

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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
