GeForce GTX 1050 vs Radeon HD 4870 X2

Intro

The GeForce GTX 1050 has a core clock speed of 1354 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 32 ROPs.

Compare all that to the Radeon HD 4870 X2, which features a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce GTX 1050 114688 MB/sec
Difference: 115712 (101%)

Texel Rate

The Radeon HD 4870 X2 should be a small bit (more or less 11%) faster with regards to anisotropic filtering than the GeForce GTX 1050. (explain)

Radeon HD 4870 X2 60000 Mtexels/sec
GeForce GTX 1050 54160 Mtexels/sec
Difference: 5840 (11%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 is the winner, and very much so. (explain)

GeForce GTX 1050 43328 Mpixels/sec
Radeon HD 4870 X2 24000 Mpixels/sec
Difference: 19328 (81%)

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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
