Compare any two graphics cards:
VS

GeForce GTX 1050 Ti vs Radeon HD 4870 X2

Intro

The GeForce GTX 1050 Ti has a GPU clock speed of 1290 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 Texture Address Units, and 32 ROPs.

Compare that to the Radeon HD 4870 X2, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 RAM runs at a frequency of 900 MHz on this particular card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

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

As far as performance goes, the Radeon HD 4870 X2 should in theory be a lot superior to the GeForce GTX 1050 Ti in general. (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 should be a small bit (approximately 3%) more effective at texture filtering 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1050 Ti is the winner, by far. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core 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 that the graphics chip can 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
