GeForce GT 1030 vs Radeon HD 4830 512MB

Intro

The GeForce GT 1030 features 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 features 384 SPUs, 32 TAUs, and 16 ROPs.

Compare that to the Radeon HD 4830 512MB, which comes with a clock frequency of 575 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

Radeon HD 4830 512MB 57600 MB/sec
GeForce GT 1030 49152 MB/sec
Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be a lot (approximately 120%) better at anisotropic filtering than the Radeon HD 4830 512MB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 4830 512MB 18400 Mtexels/sec
Difference: 22080 (120%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 1030 is the winner, and very much so. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 4830 512MB 9200 Mpixels/sec
Difference: 11040 (120%)

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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 the texel rate, the better the video 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
