GeForce GTX 1630 vs Radeon HD 5830

Intro

Compare all that to the Radeon HD 5830, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 256-bit bus. It also is made up of 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.

GeForce GTX 1630		98304 MB/sec
	Difference: 29696 (30%)

Texel Rate

The GeForce GTX 1630 should be a lot (more or less 24%) more effective at anisotropic filtering than the Radeon HD 5830. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 10880 (24%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 15040 (118%)

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 max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
