GeForce RTX 3090 vs Nvidia Titan Xp

Intro

Compare those specs to the Nvidia Titan Xp, which features a clock speed of 1582 MHz and a GDDR5X memory frequency of 1426 MHz. It also makes use of a 384-bit memory bus, and uses a 16 nm design. It is made up of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Nvidia Titan Xp		250 Watts
GeForce RTX 3090		350 Watts
	Difference: 100 Watts (40%)

Memory Bandwidth

Theoretically, the GeForce RTX 3090 should perform much faster than the Nvidia Titan Xp overall. (explain)

GeForce RTX 3090		958668 MB/sec
Nvidia Titan Xp		560845 MB/sec
	Difference: 397823 (71%)

Texel Rate

The GeForce RTX 3090 should be quite a bit (about 21%) better at texture filtering than the Nvidia Titan Xp. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Nvidia Titan Xp		379680 Mtexels/sec
	Difference: 77880 (21%)

Pixel Rate

The GeForce RTX 3090 will be a small bit (approximately 3%) better at FSAA than the Nvidia Titan Xp, and also should be capable of handling higher resolutions better. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Nvidia Titan Xp		151872 Mpixels/sec
	Difference: 4368 (3%)

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 transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could 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 core 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
