GeForce GT 1030 vs Radeon HD 4730

Intro

Compare those specifications to the Radeon HD 4730, which comes with GPU clock speed of 700 MHz, and 512 MB of GDDR5 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 640(128x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon HD 4730 will be 17% faster than the GeForce GT 1030 in general, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GT 1030 should be a lot (approximately 81%) faster with regards to anisotropic filtering 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 screen resolution 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 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: Memory bandwidth is the max amount of information (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 bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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