Radeon HD 6750 1GB vs Radeon R9 M365X

Intro

The Radeon HD 6750 1GB features a core clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 720 SPUs, 36 TAUs, and 16 ROPs.

Compare all that to the Radeon R9 M365X, which features core speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 6750 1GB 26100 Mtexels/sec
Difference: 10900 (42%)

Pixel Rate

The Radeon R9 M365X should be much (approximately 28%) more effective at full screen anti-aliasing than the Radeon HD 6750 1GB, and also capable of handling higher resolutions more effectively. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 6750 1GB 11600 Mpixels/sec
Difference: 3200 (28%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 processed per second. This number is calculated by multiplying the total amount 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
