GeForce GTX 1050 Ti vs Radeon HD 3870 X2 512MB

Intro

The GeForce GTX 1050 Ti has a core clock speed of 1290 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is comprised of 768 SPUs, 48 TAUs, and 32 ROPs.

Compare that to the Radeon HD 3870 X2 512MB, which comes with a core clock speed of 825 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3870 X2 512MB should be just a bit faster than the GeForce GTX 1050 Ti in general. (explain)

Radeon HD 3870 X2 512MB 115200 MB/sec
GeForce GTX 1050 Ti 114688 MB/sec
Difference: 512 (0%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (about 135%) better at anisotropic filtering than the Radeon HD 3870 X2 512MB. (explain)

GeForce GTX 1050 Ti 61920 Mtexels/sec
Radeon HD 3870 X2 512MB 26400 Mtexels/sec
Difference: 35520 (135%)

Pixel Rate

The GeForce GTX 1050 Ti should be quite a bit (approximately 56%) faster with regards to AA than the Radeon HD 3870 X2 512MB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1050 Ti 41280 Mpixels/sec
Radeon HD 3870 X2 512MB 26400 Mpixels/sec
Difference: 14880 (56%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of 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.
