GeForce GT 1030 vs Radeon HD 4790

Intro

The GeForce GT 1030 has core 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 all that to the Radeon HD 4790, which has GPU core speed of 600 MHz, and 512 MB of GDDR5 RAM running 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 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 should be quite a bit (approximately 111%) more effective at texture 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 running with 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past 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 memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
