GeForce GT 1030 vs Radeon HD 4730

Intro

Compare all that to the Radeon HD 4730, which comes with core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR5 memory. It features 640(128x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.

GeForce GT 1030		30 Watts
Radeon HD 4730		140 Watts
	Difference: 110 Watts (367%)

Memory Bandwidth

The Radeon HD 4730, in theory, should be a small bit faster than the GeForce GT 1030 overall. (explain)

Radeon HD 4730		57600 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 is a lot (about 81%) better at AF than the Radeon HD 4730. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 18080 (81%)

Pixel Rate

If running with a high resolution 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 4730		5600 Mpixels/sec
	Difference: 14640 (261%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
