How the RTX 4090 and 4080 Evaluate to the RTX 3090 Ti and 3080 Ti

After months of rumors and teasing, Nvidia lastly introduced the RTX 40 sequence of graphics playing cards throughout its GTC 2022 keynote. Utilizing Ada Lovelace’s new graphics structure, the RTX 40 sequence will function the successor to the RTX sequence 30, which began again in 2020.

With the RTX 40 sequence launching lower than a month from now, let’s check out the specs, dig into the very best options, and see how the primary GPUs within the RTX 40 household stack up in opposition to the RTX 3090 Ti and RTX 3080 Ti.

RTX 40 vs. RTX 3090 Ti and 3080 Ti: A Transient Overview

As the main points be aware above, many adjustments are coming from the RTX 30 sequence to the RTX 40 sequence. Nonetheless, the specs usually are not completely different from the Ti variants of the RTX 3090 and 3080, and the RTX 40 sequence all use GDDR6X reminiscence.

Nvidia claims that the RTX 4080 variants will provide two to 4 occasions the efficiency of the RTX 3080 Ti. In the meantime, the RTX 4090 Ti is claimed to be two to 4 occasions quicker than the RTX 3090 Ti.

Different notable similarities embrace GPUs that assist {hardware} ray tracing in addition to Nvidia’s flagship upsampling expertise, DLSS. Whereas the RTX 30-series helps DLSS, there are variations that we’ll focus on within the subsequent part.

One other fascinating be aware is that there are two variants of the RTX 4080: one with 16GB of GDDR6X reminiscence, which can promote for $1,199, and one other with 12GB of GDDR6X reminiscence which can value $899. This would not be the primary time Nvidia has executed this, as the corporate launched two completely different variations of its RTX 3080 graphics playing cards – the launch mannequin included 10GB of reminiscence, whereas one other model launched nearly two years later included 12GB of reminiscence.

However reminiscence (and worth) is not the one distinction between the 2 RTX 4080 variants. The 16GB mannequin has extra RT, Tensor, and CUDA cores and requires at the least 750W of energy. In distinction, the 12GB mannequin has a better core and overclock and requires at the least 700W of energy.

RTX 40 vs. RTX 3090 Ti and 3080 Ti: Structure

The RTX 30 sequence is constructed on Nvidia’s Ampere graphics structure, which makes use of Samsung’s 8nm expertise. In the meantime, the RTX 40 sequence is constructed on the brand new Ada Lovelace structure, which makes use of TSMC’s 4nm N4 expertise.

The Ampere structure is the second technology RTX, which makes use of third technology Tensor and second technology RT cores. The Ada Lovelace structure, named after the mathematician and creator, is a third-generation RTX, utilizing fourth-generation Tensor cores and third-generation RT cores. And as you’d anticipate for a brand new technology of microarchitecture, every Lovelace RT and Tensor core is extra highly effective than every Ampere RT and Tensor core.

The Lovelace structure can be the one mannequin structure to assist the brand new third technology DLSS. Nvidia famous in a weblog submit that DLSS 3 is “powered by the brand new fourth-generation Tensor Cores and Optical Circulation Accelerator,” which is just obtainable within the RTX 40 sequence.

After all, this comparability solely tells the story on paper, and we can’t understand how the GPUs examine till we get an opportunity to benchmark the RTX 40 sequence ourselves. Nonetheless, the brand new graphics design and improvement course of reveals promising indicators that this might be a step up in efficiency between the 2 generations of GeForce graphics playing cards.
