GeForce GTX 960 vs Radeon HD 5670

Intro

Compare those specifications to the Radeon HD 5670, which comes with a core clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Radeon HD 5670		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The GeForce GTX 960 should be a lot (more or less 365%) more effective at texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 960		72128 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 56628 (365%)

Pixel Rate

The GeForce GTX 960 is quite a bit (about 482%) better at full screen anti-aliasing than the Radeon HD 5670, and capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 29864 (482%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
