GeForce GTX 1630 vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which has GPU core speed of 725 MHz, and 512 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 ROPs.

Radeon HD 6750		64000 MB/sec
	Difference: 34304 (54%)

Texel Rate

The GeForce GTX 1630 is quite a bit (approximately 113%) faster with regards to texture filtering than the Radeon HD 6750. (explain)

GeForce GTX 1630		55680 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 29580 (113%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is superior to the Radeon HD 6750, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 16240 (140%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better 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 that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
