GeForce GT 1030 vs Radeon HD 3870 X2 512MB

Intro

The GeForce GT 1030 comes with a GPU core clock speed of 1265 MHz, and the 2048 MB of GDDR5 memory is set to run at 1502 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 3870 X2 512MB, which features a core clock frequency of 825 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It features 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3870 X2 512MB should in theory be a lot faster than the GeForce GT 1030 overall. (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 quite a bit (about 53%) faster with regards to anisotropic filtering 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

The Radeon HD 3870 X2 512MB is much (about 30%) better at FSAA than the GeForce GT 1030, and capable of handling higher resolutions more effectively. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of 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.
