GeForce GT 1030 vs Radeon HD 4750

Intro

Compare those specs to the Radeon HD 4750, which has a core clock frequency of 730 MHz and a GDDR5 memory frequency of 800 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation 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

Theoretically speaking, the Radeon HD 4750 will be 4% quicker than the GeForce GT 1030 overall, because of its greater data rate. (explain)

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

Texel Rate

The GeForce GT 1030 is a lot (about 73%) faster with regards to 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 will be quite a bit (about 73%) more effective at anti-aliasing than the Radeon HD 4750, and also should be able to handle higher resolutions better. (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: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
