GeForce GT 1030 vs Radeon HD 4730

Intro

Compare those specs to the Radeon HD 4730, which has a core clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

GeForce GT 1030		49152 MB/sec
	Difference: 8448 (17%)

Texel Rate

The GeForce GT 1030 should be quite a bit (about 81%) more effective at 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

The GeForce GT 1030 is a lot (about 261%) faster with regards to FSAA than the Radeon HD 4730, and also able to handle higher resolutions without losing too much performance. (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 data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
