GeForce GTX 650 Ti vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which features a clock speed of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti		110 Watts
Radeon RX 6800		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should perform quite a bit faster than the GeForce GTX 650 Ti overall. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 437888 (507%)

Texel Rate

The Radeon RX 6800 should be a lot (approximately 587%) better at anisotropic filtering than the GeForce GTX 650 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 348608 (587%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6800 is superior to the GeForce GTX 650 Ti, and very much so. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 148352 (999%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
