Radeon HD 6750 vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which has a clock speed of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X is 13% quicker than the Radeon HD 6750 in general, because of its greater data rate. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M365X will be much (about 42%) better at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 10900 (42%)

Pixel Rate

The Radeon R9 M365X will be much (more or less 28%) faster with regards to AA than the Radeon HD 6750, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 6750		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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
