GeForce GTX 1630 vs Radeon HD 4790

Intro

Compare all that to the Radeon HD 4790, which comes with GPU clock speed of 600 MHz, and 512 MB of GDDR5 RAM set to run at 800 MHz through a 256-bit bus. It also is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4790 should be a little bit faster than the GeForce GTX 1630 in general. (explain)

Radeon HD 4790		102400 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 4096 (4%)

Texel Rate

The GeForce GTX 1630 is much (approximately 190%) more effective at AF than the Radeon HD 4790. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 36480 (190%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1630 is superior to the Radeon HD 4790, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 18240 (190%)

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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
