GeForce GTX Titan Black vs GeForce RTX 4080

Intro

Compare those specifications to the GeForce RTX 4080, which makes use of a 4 nm design. nVidia has set the core speed at 2205 MHz. The GDDR6X memory is set to run at a speed of 1400 MHz on this specific card. It features 9728 SPUs along with 304 Texture Address Units and 112 ROPs.

GeForce GTX Titan Black		213360 Mtexels/sec
	Difference: 456960 (214%)

Pixel Rate

The GeForce RTX 4080 will be a lot (about 479%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan Black, and capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 204288 (479%)

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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
