GeForce GTX Titan Black vs Radeon HD 4750

Intro

Compare all of that to the Radeon HD 4750, which comes with GPU clock speed of 730 MHz, and 512 MB of GDDR5 RAM set to run at 800 MHz through a 128-bit bus. It also is made up of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 4750		51200 MB/sec
	Difference: 284800 (556%)

Texel Rate

The GeForce GTX Titan Black is a lot (more or less 813%) better at texture filtering than the Radeon HD 4750. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 190000 (813%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan Black is superior to the Radeon HD 4750, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 30992 (265%)

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 information (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
