GeForce GTX 960 vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular card. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce GTX 960		120 Watts
	Difference: 34 Watts (40%)

Memory Bandwidth

In theory, the GeForce GTX 960 will be 75% quicker than the Radeon HD 6750 overall, because of its higher data rate. (explain)

GeForce GTX 960		112000 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 48000 (75%)

Texel Rate

The GeForce GTX 960 should be a lot (approximately 176%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GTX 960		72128 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 46028 (176%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the Radeon HD 6750, by a large margin. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 24464 (211%)

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 information (counted in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
