GeForce GTX 960 vs Radeon HD 4750

Intro

Compare that to the Radeon HD 4750, which comes with a GPU core clock speed of 730 MHz, and 512 MB of GDDR5 memory set to run at 800 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 TAUs, and 16 ROPs.

The GeForce GTX 960 should be a lot (more or less 209%) better at anisotropic filtering than the Radeon HD 4750. (explain)

GeForce GTX 960		72128 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 48768 (209%)

Pixel Rate

The GeForce GTX 960 should be quite a bit (more or less 209%) better at FSAA than the Radeon HD 4750, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 24384 (209%)

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 (measured in MB per second) that can be transferred 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 the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 are applied per second. This number is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 number of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
