Radeon HD 5670 vs Radeon R9 M365X

Intro

The Radeon HD 5670 has a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon R9 M365X, which comes with GPU clock speed of 925 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory perform a little bit faster than the Radeon HD 5670 overall. (explain)

Radeon R9 M365X 72000 MB/sec
Radeon HD 5670 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M365X should be quite a bit (approximately 139%) better at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 21500 (139%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M365X is the winner, by a large margin. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 8600 (139%)

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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
