GeForce GTX 1050 Ti vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTX 1050 Ti features a clock speed of 1290 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 14 nm design. It is made up of 768 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon HD 3870 X2 1GB, which features core clock speeds of 825 MHz on the GPU, and 1126 MHz on the 1024 MB of GDDR4 RAM. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 3870 X2 1GB should in theory be quite a bit better than the GeForce GTX 1050 Ti overall. (explain)

Radeon HD 3870 X2 1GB 144128 MB/sec
GeForce GTX 1050 Ti 114688 MB/sec
Difference: 29440 (26%)

Texel Rate

The GeForce GTX 1050 Ti should be a lot (more or less 135%) faster with regards to AF than the Radeon HD 3870 X2 1GB. (explain)

GeForce GTX 1050 Ti 61920 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 35520 (135%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1050 Ti is superior to the Radeon HD 3870 X2 1GB, by far. (explain)

GeForce GTX 1050 Ti 41280 Mpixels/sec
Radeon HD 3870 X2 1GB 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
