GeForce GT 1030 vs Radeon HD 4750

Intro

Compare those specs to the Radeon HD 4750, which comes with GPU clock speed of 730 MHz, and 512 MB of GDDR5 memory running at 800 MHz through a 128-bit bus. It also is made up of 640(128x5) Stream Processors, 32 TAUs, and 16 ROPs.

GeForce GT 1030		49152 MB/sec
	Difference: 2048 (4%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 73%) better at anisotropic filtering than the Radeon HD 4750. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4750		23360 Mtexels/sec
	Difference: 17120 (73%)

Pixel Rate

The GeForce GT 1030 should be a lot (approximately 73%) more effective at full screen anti-aliasing than the Radeon HD 4750, and capable of handling higher resolutions while still performing well. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4750		11680 Mpixels/sec
	Difference: 8560 (73%)

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 MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per 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 called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
