GeForce GTX 1070 vs Radeon HD 6750 1GB

Intro

Compare all that to the Radeon HD 6750 1GB, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Radeon HD 6750 1GB		64000 MB/sec
	Difference: 198144 (310%)

Texel Rate

The GeForce GTX 1070 should be a lot (about 592%) better at AF than the Radeon HD 6750 1GB. (explain)

GeForce GTX 1070		180720 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 154620 (592%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1070 is a better choice, and very much so. (explain)

GeForce GTX 1070		96384 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 84784 (731%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one 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 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
