GeForce GTX 960 vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core speed at 1626 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this card. It features 1792 SPUs along with 112 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 960		120 Watts
Radeon RX 6600		132 Watts
	Difference: 12 Watts (10%)

Memory Bandwidth

In theory, the Radeon RX 6600 should be 105% faster than the GeForce GTX 960 in general, due to its greater data rate. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 117376 (105%)

Texel Rate

The Radeon RX 6600 is much (approximately 152%) more effective at anisotropic filtering than the GeForce GTX 960. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 960		72128 Mtexels/sec
	Difference: 109984 (152%)

Pixel Rate

The Radeon RX 6600 is a lot (about 189%) better at full screen anti-aliasing than the GeForce GTX 960, and will be able to handle higher resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 960		36064 Mpixels/sec
	Difference: 68000 (189%)

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 (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better 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 amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
