Nvidia unveils GeForce RTX 4080, RTX 4090 and Portal RTX

As expected, Nvidia announced the GeForce RTX 4090 during its release GeForce Beyond Live Streaming – Confirmed RTX 4080 as a good benchmark. Both GPUs are based on Nvidia’s new Ada Lovelace architecture, and will launch this year: the RTX 4090 on October 12, and the RTX 4080 sometime in November.

Key features of Ada Lovelace, and therefore these new cards, include 3rd generation RT cores, 4th generation Tensor cores, and new streaming multiprocessors. These should add up to twice the performance of Ampere (this is the RTX 30 series architecture that currently dominates the The best graphics card proof) in standard pixelated games, and up to four times the performance in ray tracing games. And since Nvidia was in a volatile mood, they also took the opportunity to reveal RTX Gate: a semi-official copy of the original outlet It upgrades it with RT lighting and reflection effects. Corer.

First, though, are those GPUs. The RTX 4090 packs 24 GB of GDDR6X RAM and will cost $1,599; Just puts it a few hundred dollars under RTX 3090 Ti, although Nvidia says it outperforms the high-end Ampere GPU by up to four times. Meanwhile, there will be two versions of the RTX 4080: a 12GB GDDR6X model starting at $899, and a 16GB model starting at $1199. Both are much more expensive than RTX 3080which launched at $699, although at least the 16GB model is supposed to be four times faster than the 16GB model. RTX 3080 Ti. I asked for UK rates and will update this article if I get it.

If they can get into the Holy Land to boost 4x performance, it will likely be through ray tracing, and in particular, DLSS. Ada Lovelace’s “Shader Execution Reordering” feature reschedules RT workloads on the go, so that the GPU can process ray-traced frames more efficiently (and therefore faster). The RTX 40 series GPUs will also be the first to support DLSS 3, a new version of Nvidia’s deep learning supersampling tool. This uses chassis hardware and improved AI to create whole new frames in the upgrade process, not just recreate frames that have already been rendered, resulting in a massive increase in FPS.

How huge? Results will vary depending on the game, and even the file Cyberpunk 2077 movie And the Microsoft Flight Simulator The demos that Nvidia showed during the live stream weren’t terribly helpful due to the lack of specific settings provided. But with its maxed out graphics and ray tracing, it showed that Cyberpunk 2077 jumps from around 20-25 fps without DLSS to over 60 fps with DLSS 3, so it obviously has some chops. Nearly 40 games They are confirmed to have DLSS 3 support, which is already much more than the latest AMD support FSR 2.1.0 Update upscaler, these include the likes of Cyberpunk 2077, Flight Sim, Hitman 3, Atomic Heart, and The Witcher 3: Wild Hunt.


Another DLSS 3 game is Portal RTX, which is coming to Steam later this year as a free download for Portal owners. I’ll leave opinions on how ray tracing affects the aesthetic of the Portal between you and your eyeballs, but it looks great from a purely technical standpoint. And in what could be an even more interesting version, the tool used to make it – nvidia remix – It will also be released for free. Remix aims to help modders easily create ray tracing mods, including support for DLSS 3 and Nvidia Reflex, by allowing them to import a game into the tool and add these features with just a few clicks. It even uses AI to create entirely new models and assets that replace the game’s less accurate original models.

This sounds crazy, but it looks like it is who – which Straightforward – it looks like games just need to be based on DX8 or DX9 and use a “fixed function graphics pipeline”, which I’ll admit is entering a technical area that I don’t understand. But Nvidia has already shown how well it could work with a remix-ified look at The Elder Scrolls III: Morrowind, which It looks like a complete remake. Not that I’m ever advocating AI to replace actual art, but I’m definitely looking forward to seeing what people can do with this.

I will also aim to have an RTX 4090 and at least one of the RTX 4080 variants in my glove ASAP. Unlike the RTX 30 series, Nvidia chose to raise prices this time around – let’s see if it’s really worth it.
