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 memory. It features 384 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 4830 1GB, which features a GPU core clock speed of 575 MHz, and 1024 MB of GDDR4 memory running at 900 MHz through a 256-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, 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 (approximately 120%) more effective at AF 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 the winner, by far. (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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. 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 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.
