GeForce GT 1030 vs Radeon HD 4790

Intro

The GeForce GT 1030 has clock speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 4790, which comes with core speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 memory. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 4790, in theory, should perform quite a bit faster than the GeForce GT 1030 overall. (explain)

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

Texel Rate

The GeForce GT 1030 will be 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 the winner, 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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied 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 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 that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
