GeForce RTX 4070 Ti vs Radeon RX 6800

Intro

Compare all that to the Radeon RX 6800, which comes with GPU core speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also features 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Radeon RX 6800		250 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 35 Watts (14%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 should in theory be just a bit better than the GeForce RTX 4070 Ti overall. (explain)

Radeon RX 6800		524288 MB/sec
GeForce RTX 4070 Ti		516096 MB/sec
	Difference: 8192 (2%)

Texel Rate

The GeForce RTX 4070 Ti will be quite a bit (about 36%) more effective at texture filtering than the Radeon RX 6800. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
Radeon RX 6800		408000 Mtexels/sec
	Difference: 146400 (36%)

Pixel Rate

The GeForce RTX 4070 Ti is a little bit (approximately 13%) faster with regards to full screen anti-aliasing than the Radeon RX 6800, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
Radeon RX 6800		163200 Mpixels/sec
	Difference: 21600 (13%)

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 maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
