VS

GeForce RTX 3080 12 GB vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3080 12 GB features a GPU clock speed of 1260 MHz, and the 12288 MB of GDDR6X memory runs at 1188 MHz through a 384-bit bus. It also is comprised of 8960 SPUs, 280 TAUs, and 112 Raster Operation Units.

Compare all of that to the GeForce RTX 3080 Ti, which features a clock frequency of 1365 MHz and a GDDR6X memory speed of 1188 MHz. It also features a 384-bit memory bus, and uses a 8 nm design. It is comprised of 10240 SPUs, 320 TAUs, and 112 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 12 GB is 0% faster than the GeForce RTX 3080 Ti in general, because of its greater data rate. (explain)

GeForce RTX 3080 12 GB 934298 MB/sec
GeForce RTX 3080 Ti 934297 MB/sec
Difference: 1 (0%)

Texel Rate

The GeForce RTX 3080 Ti is much (about 24%) faster with regards to AF than the GeForce RTX 3080 12 GB. (explain)

GeForce RTX 3080 Ti 436800 Mtexels/sec
GeForce RTX 3080 12 GB 352800 Mtexels/sec
Difference: 84000 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is superior to the GeForce RTX 3080 12 GB, but it probably won't make a huge difference. (explain)

GeForce RTX 3080 Ti 152880 Mpixels/sec
GeForce RTX 3080 12 GB 141120 Mpixels/sec
Difference: 11760 (8%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the 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 maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. 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 potential to get to the maximum fill rate.
