Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
Radeon HD 4850 X2 512MB		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Radeon HD 4850 X2 512MB is 11% quicker than the GeForce GTX 1050 Ti overall, because of its greater data rate. (explain)

Radeon HD 4850 X2 512MB		127104 MB/sec
GeForce GTX 1050 Ti		114688 MB/sec
	Difference: 12416 (11%)

Texel Rate

The GeForce GTX 1050 Ti should be quite a bit (about 24%) faster with regards to AF than the Radeon HD 4850 X2 512MB. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 4850 X2 512MB		50000 Mtexels/sec
	Difference: 11920 (24%)

Pixel Rate

The GeForce GTX 1050 Ti will be much (more or less 106%) more effective at full screen anti-aliasing than the Radeon HD 4850 X2 512MB, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4850 X2 512MB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
