GeForce GTX 1630 vs Radeon HD 4790

Intro

The GeForce GTX 1630 has a GPU core clock speed of 1740 MHz, and the 4096 MB of GDDR6 memory runs at 1500 MHz through a 64-bit bus. It also is made up of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Compare that to the Radeon HD 4790, which features 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 features 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 4790 will be 4% quicker than the GeForce GTX 1630 in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 1630 should be much (approximately 190%) better at texture filtering 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 high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by far. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
