GeForce GTX 960 vs Radeon HD 5670

Intro

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

Power Consumption (Max TDP)

Radeon HD 5670		61 Watts
GeForce GTX 960		120 Watts
	Difference: 59 Watts (97%)

Memory Bandwidth

The GeForce GTX 960 should in theory perform much faster than the Radeon HD 5670 overall. (explain)

GeForce GTX 960		112000 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The GeForce GTX 960 should be a lot (about 365%) faster with regards to AF than the Radeon HD 5670. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960 is a better choice, and very much so. (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 information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses 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 can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
