GeForce GTX Titan Black vs Radeon RX 6600

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 118 Watts (89%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black should be 46% faster than the Radeon RX 6600 overall, because of its higher data rate. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The GeForce GTX Titan Black will be just a bit (more or less 17%) more effective at anisotropic filtering than the Radeon RX 6600. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 31248 (17%)

Pixel Rate

The Radeon RX 6600 should be quite a bit (more or less 144%) better at AA than the GeForce GTX Titan Black, and should be capable of handling higher screen resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 61392 (144%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
