GeForce RTX 4080 vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which features a clock speed of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also makes use of a 384-bit memory bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
GeForce RTX 4080		320 Watts
	Difference: 70 Watts (28%)

Memory Bandwidth

Theoretically, the GeForce RTX 4080 should perform a lot faster than the Nvidia Titan X in general. (explain)

GeForce RTX 4080		734003 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 242483 (49%)

Texel Rate

The GeForce RTX 4080 should be much (more or less 111%) more effective at AF than the Nvidia Titan X. (explain)

GeForce RTX 4080		670320 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 352912 (111%)

Pixel Rate

The GeForce RTX 4080 should be quite a bit (more or less 82%) faster with regards to anti-aliasing than the Nvidia Titan X, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 4080		246960 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 110928 (82%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the maximum fill rate.
