Nvidia’s new high-end GPUs

Nvidias new high end GPUs

Nvidia has just introduced the GeForce RTX 4090 and 4080, next-gen GPUs that far outperform the RTX 3000 with several technological improvements. Monsters of graphics power at a very high price…

At its GeForce Beyond online conference, held on September 20 – viewable at Youtube and Twitch –, Nvidia has finally presented its new – and highly anticipated – graphics cards, the GeForce RTX 4090 and two GeForce RTX 4080, which are based on the brand new Ada Lovelace chip and DLSS 3 technology. graphics do most of the heavy computing in 3D PC games and software, making them key when choosing or building your computer, especially for gamers, creators and developers. And the least we can say is that Nvidia raises the bar even higher in terms of power – which will affect energy consumption and price.

Ada Lovelace: a new optimized architecture

The GeForce RTX 40XX graphics cards are the first to take advantage of the new Ada Lovelace architecture – in reference to the first computer programmer. It is a chip engraved in 4 nm by TSMC, the Taiwanese specialist which manufactures chips for Apple, AMD and many others – 5 nm less than on the Ampere architecture of the previous generation of graphics cards – which leaves more room for the transistors. It also embeds 76 billion – against 28 billion for the Ampere architecture of the GeForce RTX 3000 – which allows it to embed many more computing units. Everything has been revamped!

Thus, the performance of Ray Tracing – a rendering technique which consists of individually calculating the trajectory of a bunch of light rays to achieve a very high level of graphic fidelity – has been multiplied and offers a high top speed, which is very important. for games, but also creative or data processing software. The new Shader Execution Reordering system completely reorganizes the management of calculations and the way the GPU prioritizes them, in order to improve performance, even in the most technically demanding games – and not always well optimized.


DLSS 3: Ray Tracing at its peak

Who says new generation of graphics card, says new technologies! And one of the key arguments of the RTX 40XX is the DLSS 3, presented by Nvidia as “the next revolution in the company’s Deep Learning Super Sampling neural graphics technology for games”, with the promise of rendering up to four times faster than raw rendering. Its principle: to anticipate the images – the frames in English – by calculating the direction and speed of a pixel in the image before the GPU itself has calculated them, thanks to the Ada Optical Flow accelerator – it studies the previous frames and the current frame to anticipate movements on the next. Eventually, the number of frames per second increases, which in turn increases the number of frames displayed on the screen, and therefore the fluidity of the game.

During the conference, Nvidia gave a demonstration on the games Microsoft Flight Simulator and Cyberpunk 2077two rather demanding games. Cyberpunk 2077 went from 62 FPS in 4K in DLSS 2 to 101 FPS in DLSS 3. 35 other games – already released and to come – will be compatible with DLSS 3:

  • A Plague Tale: Requiem
  • Atomic Heart
  • Black Myth: Wu Kong
  • Bright Memory: Infinite
  • Chernobylite
  • Conqueror’s Blade
  • Cyberpunk 2077
  • Dakar-Rally
  • Deliver Us Mars
  • Destroy All Humans! 2 – Reprobed
  • Dying Light 2 Stay Human
  • F1 22
  • FIST: Forged In Shadow Torch
  • Frostbite Engine
  • HITMAN 3
  • Hogwarts Legacy
  • Jurassic World Evolution 2
  • Justice
  • Loopmancer
  • Marauders
  • Microsoft Flight Simulator
  • Midnight Ghost Hunt
  • Mount & Blade II: Bannerlord
  • Naraka: Bladepoint
  • NVIDIA Omniverse
  • NVIDIA Racer RTX
  • Portal with RTX
  • Ripout
  • STALKER 2: Heart of Chornobyl
  • Scathe Sword and Fairy 7
  • The Lord of the Rings: Gollum
  • The Witcher 3: Wild Hunt
  • Tower of Fantasy
  • Warhammer 40,000: Darktide

The RTX version of Portal, the famous Valve game released in 2007, is a real surprise, and will be free for owners of the original game next November! It was made using the NVIDIA RTX Remix tool – usable by players, not developers – which improves the graphics rendering of an old game – a bit like mods. The Elder Scrolls: Morrowind (2002) also had the right to a facelift, and the result is really impressive.

GeForce RTX 4000: impressive graphics cards… but expensive

Nvidia has placed the GeForce RTX 4090, flagship graphics card, in the spotlight, supposed to offer four times the performance of the RTX 3090 Ti – the firm even announces that it will systematically reach 100 FPS for games in 4K . It has 24 GB of GDDR6X (very high-speed graphics random access memory) and 16,384 CUDA cores. Nvidia promises twice as much energy efficiency, with 90 blocks dedicated to classic rendering (Shader Cores), 191 units dedicated to Ray Tracing (RT Cores) and 1,320 units dedicated to AI (Tensor Cores) – against 40 Shader Cores , 78 RT Cores, 320 Tensor Cores on the Ampere GPU, which was the fastest so far. But who says power, often says high energy consumption. And this is the case here, because the RTX 4090 absorbs a monster electrical power of 450 W – against “only” 350 W for the previous generation. Nvidia therefore recommends a power supply of at least 850 W based on a PC equipped with a Ryzen 5900X. The RTX 4090 will be available on October 12 at the staggering price of €1,949.

Nvidia also unveiled the GeForce RTX 4080 graphics card, which comes in two versions: one with 16 GB of GDDR6X RAM and one with 12 GB. They feature 9,728 and 7,680 CUDA cores, 40 and 49 Shader Cores, 113 and 92 RT respectively. Cores, and 780 and 39 Tensor Cores. So many features that make the RTX 4080 two to four times more powerful than the 3080 Ti. The RTX 4080s will be available next November at prices of €1,469 and €1,099. Again, the price is very high, much more than the previous generation when it was released – the GeForce RTX 3080 was launched at €719 and the GeForce RTX 3090 at €1,549. Here’s hoping the RTX 40s don’t suffer from the same supply issues as their older siblings, which could push prices up even more – not to mention the hefty electricity bill. Another small reservation: the performances shown during the conference were taken from game versions that exploit the new functions in Ray Tracing and DLSS 3; in more classic situations, the rendering may therefore be somewhat different.
