GeForce GT 1030 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 comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 4790 should be much faster than the GeForce GT 1030 in general. (explain)

Radeon HD 4790		102400 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 53248 (108%)

Texel Rate

The GeForce GT 1030 is much (more or less 111%) faster with regards to anisotropic filtering than the Radeon HD 4790. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 21280 (111%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 1030 is a better choice, and very much so. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 10640 (111%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
