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

Intro

The GeForce GTX 1050 3GB has a GPU core speed of 1392 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1750 MHz through a 96-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 24 Raster Operation Units.

Compare those specifications to the Radeon HD 3870 X2 1GB, which features GPU core speed of 825 MHz, and 1024 MB of GDDR4 memory running at 1126 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3870 X2 1GB is 68% faster than the GeForce GTX 1050 3GB in general, because of 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 should be quite a bit (approximately 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 should be much (more or less 27%) better at AA than the Radeon HD 3870 X2 1GB, and will be capable of handling higher screen resolutions more effectively. (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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
