GeForce GTX 860M vs Radeon HD 6750 1GB

Intro

Compare that to the Radeon HD 6750 1GB, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Radeon HD 6750 1GB		86 Watts
	Difference: 41 Watts (91%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 860M is a lot (approximately 193%) more effective at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 50412 (193%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is superior to the Radeon HD 6750 1GB, but it probably won't make a huge difference. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon HD 6750 1GB		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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
