Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050 Ti		75 Watts
Radeon HD 4870 X2		350 Watts
	Difference: 275 Watts (367%)

Memory Bandwidth

In theory, the Radeon HD 4870 X2 will be 101% faster than the GeForce GTX 1050 Ti in general, due to its higher data rate. (explain)

Radeon HD 4870 X2		230400 MB/sec
GeForce GTX 1050 Ti		114688 MB/sec
	Difference: 115712 (101%)

Texel Rate

The GeForce GTX 1050 Ti is just a bit (about 3%) faster with regards to AF than the Radeon HD 4870 X2. (explain)

GeForce GTX 1050 Ti		61920 Mtexels/sec
Radeon HD 4870 X2		60000 Mtexels/sec
	Difference: 1920 (3%)

Pixel Rate

The GeForce GTX 1050 Ti should be much (approximately 72%) faster with regards to anti-aliasing than the Radeon HD 4870 X2, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1050 Ti		41280 Mpixels/sec
Radeon HD 4870 X2		24000 Mpixels/sec
	Difference: 17280 (72%)

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: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
