GeForce GT 1030 vs Radeon HD 5830

Intro

Compare that to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this particular model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon HD 5830		175 Watts
	Difference: 145 Watts (483%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 is 160% faster than the GeForce GT 1030 overall, because of its greater bandwidth. (explain)

Radeon HD 5830		128000 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 78848 (160%)

Texel Rate

The Radeon HD 5830 should be a small bit (about 11%) faster with regards to anisotropic filtering than the GeForce GT 1030. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 4320 (11%)

Pixel Rate

The GeForce GT 1030 should be quite a bit (more or less 58%) faster with regards to full screen anti-aliasing than the Radeon HD 5830, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 7440 (58%)

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 largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 ability to reach the maximum fill rate.
