The GeForce GTX 960 should be a lot (more or less 140%) more effective at texture filtering than the Radeon HD 4870 2GB. (explain)

GeForce GTX 960 72128 Mtexels/sec
Radeon HD 4870 2GB 30000 Mtexels/sec
Difference: 42128 (140%)

Pixel Rate

The GeForce GTX 960 should be a lot (approximately 201%) better at AA than the Radeon HD 4870 2GB, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 960 36064 Mpixels/sec
Radeon HD 4870 2GB 12000 Mpixels/sec
Difference: 24064 (201%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 per second. This figure is worked out 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 graphics card will be at 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 record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
