Radeon HD 3850 1GB		52992 MB/sec
	Difference: 33408 (63%)

Texel Rate

The GeForce GTX 750 Ti should be a lot (more or less 282%) better at texture filtering than the Radeon HD 3850 1GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 3850 1GB		10688 Mtexels/sec
	Difference: 30112 (282%)

Pixel Rate

The GeForce GTX 750 Ti is much (approximately 53%) more effective at AA than the Radeon HD 3850 1GB, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 3850 1GB		10688 Mpixels/sec
	Difference: 5632 (53%)

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 (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
