GeForce GT 1030 vs Radeon HD 4750

Intro

Compare all of that to the Radeon HD 4750, which has core clock speeds of 730 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon HD 4750		75 Watts
	Difference: 45 Watts (150%)

Memory Bandwidth

In theory, the Radeon HD 4750 should be 4% faster than the GeForce GT 1030 in general, due to its greater bandwidth. (explain)

Radeon HD 4750		51200 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 2048 (4%)

Texel Rate

The GeForce GT 1030 is quite a bit (more or less 73%) better at texture 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 will be quite a bit (about 73%) more effective at FSAA than the Radeon HD 4750, and will be able to handle higher screen 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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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