GeForce GTX 1050 vs Radeon HD 3870 X2 1GB

Intro

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

Compare those specifications to the Radeon HD 3870 X2 1GB, which comes with a core clock frequency of 825 MHz and a GDDR4 memory frequency of 1126 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 3870 X2 1GB should theoretically be quite a bit superior to the GeForce GTX 1050 in general. (explain)

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

Texel Rate

The GeForce GTX 1050 will be much (more or less 105%) faster with regards to anisotropic filtering than the Radeon HD 3870 X2 1GB. (explain)

GeForce GTX 1050 54160 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 27760 (105%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1050 is a better choice, by far. (explain)

GeForce GTX 1050 43328 Mpixels/sec
Radeon HD 3870 X2 1GB 26400 Mpixels/sec
Difference: 16928 (64%)

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 data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few 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.
