GeForce GT 1030 vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which has GPU clock speed of 725 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also features 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Radeon HD 6750		86 Watts
	Difference: 56 Watts (187%)

Memory Bandwidth

In theory, the Radeon HD 6750 is 30% quicker than the GeForce GT 1030 overall, due to its greater bandwidth. (explain)

Radeon HD 6750		64000 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 14848 (30%)

Texel Rate

The GeForce GT 1030 will be much (about 55%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 14380 (55%)

Pixel Rate

The GeForce GT 1030 is quite a bit (approximately 74%) faster with regards to AA than the Radeon HD 6750, and capable of handling higher resolutions while still performing well. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 8640 (74%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
