Radeon RX 6600 vs Radeon VII

Intro

Compare that to the Radeon VII, which uses a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 RAM runs at a frequency of 1000 MHz on this model. It features 3840 SPUs along with 240 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon VII		295 Watts
	Difference: 163 Watts (123%)

Memory Bandwidth

The Radeon VII, in theory, should be a lot faster than the Radeon RX 6600 in general. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 819200 (357%)

Texel Rate

The Radeon VII will be quite a bit (approximately 85%) faster with regards to texture filtering than the Radeon RX 6600. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 153888 (85%)

Pixel Rate

The Radeon RX 6600 should be a small bit (about 16%) more effective at AA than the Radeon VII, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 14464 (16%)

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 information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
