GeForce GTX 1050 vs Radeon HD 3870 X2 1GB

Intro

The GeForce GTX 1050 comes with core speeds of 1354 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon HD 3870 X2 1GB, which makes use of a 55 nm design. AMD has clocked the core speed at 825 MHz. The GDDR4 RAM works at a speed of 1126 MHz on this card. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3870 X2 1GB should in theory be a lot faster than the GeForce GTX 1050 overall. (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 a lot (approximately 105%) faster with regards to texture 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

The GeForce GTX 1050 is a lot (about 64%) more effective at anti-aliasing than the Radeon HD 3870 X2 1GB, and also should be able to handle higher resolutions better. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
