GeForce GT 1030 vs Radeon HD 3870 X2 512MB

Intro

The GeForce GT 1030 has core speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Radeon HD 3870 X2 512MB, which has core clock speeds of 825 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 3870 X2 512MB should be much faster than the GeForce GT 1030 in general. (explain)

Radeon HD 3870 X2 512MB 115200 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 66048 (134%)

Texel Rate

The GeForce GT 1030 should be much (about 53%) more effective at AF than the Radeon HD 3870 X2 512MB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 3870 X2 512MB 26400 Mtexels/sec
Difference: 14080 (53%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 3870 X2 512MB is a better choice, by far. (explain)

Radeon HD 3870 X2 512MB 26400 Mpixels/sec
GeForce GT 1030 20240 Mpixels/sec
Difference: 6160 (30%)

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 data (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
