GeForce GTX 750 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
Radeon RX 6600		132 Watts
	Difference: 77 Watts (140%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6600 is 187% faster than the GeForce GTX 750 overall, because of its higher bandwidth. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 149376 (187%)

Texel Rate

The Radeon RX 6600 is quite a bit (more or less 458%) more effective at texture filtering than the GeForce GTX 750. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 149472 (458%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, and very much so. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 87744 (538%)

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 data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
