GeForce GTX 650 vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has set the core speed at 1626 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this card. 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 650		64 Watts
Radeon RX 6600		132 Watts
	Difference: 68 Watts (106%)

Memory Bandwidth

The Radeon RX 6600 should theoretically perform much faster than the GeForce GTX 650 in general. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 650		80000 MB/sec
	Difference: 149376 (187%)

Texel Rate

The Radeon RX 6600 should be much (more or less 438%) more effective at anisotropic filtering than the GeForce GTX 650. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 148256 (438%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 is the winner, by far. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 87136 (515%)

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 MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
