GeForce GT 1030 vs Radeon HD 4830 1GB

Intro

The GeForce GT 1030 features core clock speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare that to the Radeon HD 4830 1GB, which features a core clock frequency of 575 MHz and a GDDR4 memory frequency of 900 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is made up of 640(128x5) SPUs, 32 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GT 1030 will be a lot (more or less 120%) more effective at anisotropic filtering than the Radeon HD 4830 1GB. (explain)

GeForce GT 1030 40480 Mtexels/sec
Radeon HD 4830 1GB 18400 Mtexels/sec
Difference: 22080 (120%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is superior to the Radeon HD 4830 1GB, by a large margin. (explain)

GeForce GT 1030 20240 Mpixels/sec
Radeon HD 4830 1GB 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 max amount of information (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
