Radeon HD 6750 1GB vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which features a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 6750 1GB should theoretically be quite a bit better than the Radeon R7 M260 overall. (explain)

Radeon HD 6750 1GB		64000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 1GB should be much (about 52%) more effective at AF than the Radeon R7 M260. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 8940 (52%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is superior to the Radeon R7 M260, by a large margin. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 5880 (103%)

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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
