GeForce GT 1030 vs Radeon HD 3870 512MB

Intro

The GeForce GT 1030 features a GPU clock speed of 1265 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1502 MHz through a 64-bit bus. It also features 384 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon HD 3870 512MB, which comes with core speeds of 775 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Radeon HD 3870 512MB 57600 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be quite a bit (about 226%) faster with regards to texture filtering than the Radeon HD 3870 512MB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 3870 512MB 12400 Mtexels/sec
Difference: 28080 (226%)

Pixel Rate

The GeForce GT 1030 should be much (about 63%) better at anti-aliasing than the Radeon HD 3870 512MB, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 3870 512MB 12400 Mpixels/sec
Difference: 7840 (63%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
