GeForce GTX 860M vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory works at a speed of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Radeon HD 6750		86 Watts
	Difference: 41 Watts (91%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX 860M should be a lot (about 193%) better at AF than the Radeon HD 6750. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 50412 (193%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 860M is a better choice, but not by far. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 1152 (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 largest amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of 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 in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
