Radeon HD 6750 vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which has GPU core speed of 800 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M370X should be a bit faster than the Radeon HD 6750 overall. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X should be quite a bit (about 23%) faster with regards to AF than the Radeon HD 6750. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 5900 (23%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M370X is a better choice, but only just. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 1200 (10%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
