GeForce GTX 1050 Ti vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTX 1050 Ti comes with 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 TAUs, and 32 ROPs.

Compare those specs to the Radeon HD 3870 X2 1GB, which comes with a GPU core clock speed of 825 MHz, and 1024 MB of GDDR4 RAM running at 1126 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3870 X2 1GB will be 26% faster than the GeForce GTX 1050 Ti in general, due to its greater data rate. (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 is quite a bit (about 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 a large margin. (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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 video 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 that the graphics chip could 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
