GeForce GT 1030 vs Radeon HD 4830 512MB

Intro

Compare that to the Radeon HD 4830 512MB, which has a GPU core clock speed of 575 MHz, and 512 MB of GDDR3 RAM running at 900 MHz through a 256-bit bus. It also is made up of 640(128x5) SPUs, 32 TAUs, and 16 Raster Operation Units.

GeForce GT 1030		49152 MB/sec
	Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 120%) more effective 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 using high levels of AA is important to you, then the GeForce GT 1030 is a better choice, by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
