The GeForce GTX 1050 Ti is a lot (about 24%) faster with regards to texture filtering than the Radeon HD 4850 X2 1GB. (explain)

GeForce GTX 1050 Ti 61920 Mtexels/sec
Radeon HD 4850 X2 1GB 50000 Mtexels/sec
Difference: 11920 (24%)

Pixel Rate

The GeForce GTX 1050 Ti will be quite a bit (about 106%) more effective at full screen anti-aliasing than the Radeon HD 4850 X2 1GB, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050 Ti 41280 Mpixels/sec
Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Difference: 21280 (106%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
