GeForce GTX 1050 3GB vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTX 1050 3GB has a clock speed of 1392 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 96-bit bus, and makes use of a 14 nm design. It is comprised of 768 SPUs, 48 Texture Address Units, and 24 Raster Operation Units.

Compare all that to the Radeon HD 3870 X2 1GB, which has a GPU core clock speed of 825 MHz, and 1024 MB of GDDR4 RAM set to run at 1126 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3870 X2 1GB should be 68% faster than the GeForce GTX 1050 3GB overall, due to its greater data rate. (explain)

Radeon HD 3870 X2 1GB 144128 MB/sec
GeForce GTX 1050 3GB 86016 MB/sec
Difference: 58112 (68%)

Texel Rate

The GeForce GTX 1050 3GB will be a lot (more or less 153%) better at texture filtering than the Radeon HD 3870 X2 1GB. (explain)

GeForce GTX 1050 3GB 66816 Mtexels/sec
Radeon HD 3870 X2 1GB 26400 Mtexels/sec
Difference: 40416 (153%)

Pixel Rate

The GeForce GTX 1050 3GB is quite a bit (approximately 27%) better at FSAA than the Radeon HD 3870 X2 1GB, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1050 3GB 33408 Mpixels/sec
Radeon HD 3870 X2 1GB 26400 Mpixels/sec
Difference: 7008 (27%)

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 megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
