GeForce GTX 1070 vs Radeon HD 5670

Intro

Compare those specifications to the Radeon HD 5670, which features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

GeForce GTX 1070		180720 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 165220 (1066%)

Pixel Rate

The GeForce GTX 1070 is much (approximately 1455%) more effective at AA than the Radeon HD 5670, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1070		96384 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 90184 (1455%)

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 data (in units of MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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