GeForce GTX 970 vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Radeon HD 6750		64000 MB/sec
	Difference: 160000 (250%)

Texel Rate

The GeForce GTX 970 is much (about 318%) faster with regards to AF than the Radeon HD 6750. (explain)

GeForce GTX 970		109200 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 83100 (318%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 970 is the winner, by far. (explain)

GeForce GTX 970		67200 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 55600 (479%)

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 information (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
