Nvidia announces RTX 4090 and 4080 graphics cards, DLSS 3

Nvidia introduced its newest era GeForce RTX graphics playing cards at its GTC AI convention. The Nvidia RTX 4090 and RTX 4080 are the primary GPUs within the ‘Ada Lovelace’ sequence and must be as much as twice as quick in rasterized video games and as much as 4 instances sooner in ray-traced video games than their last-gen counterparts. .

The RTX 4090 24GB can be accessible on October 12 and can price $1599/£1679, whereas the RTX 4080 16GB can be accessible in November and price $1199/£1269. There’s additionally an RTX 4080 12GB mannequin that prices $899 / £949. The 4090 and 4080 are reportedly two to 4 instances sooner than their Ampere equivalents, the 3090 Ti and 3080 Ti, respectively.

The RTX 4090 has already arrived at Digital Foundry HQ, and we’re taking its steps…

Be aware that Nvidia RTX 30-series playing cards will stay on sale for now and fill the decrease finish of the market till lower-end RTX 40-series GPUs arrive.

Nvidia’s RTX 4090 and 4080 graphics playing cards are proven in Founders Version guise.

So how are these GPUs so quick? The 40 sequence GPUs use TSMC’s ‘4N’ course of and boast as much as 76 billion transistors and as much as 18,000 CUDA cores, 70 p.c greater than the final era Ampere. The brand new course of additionally permits the era to be considerably extra energy environment friendly, however we anticipate flagship playing cards to be as energy hungry as they are saying – you get a ton of additional efficiency to offset that by way of effectivity.

The brand new stream multiprocessor makes use of a brand new shader execution reordering (SER) method that Nvidia claims supplies “two to 3 instances acceleration” for ray tracing and a 25 p.c enchancment for rasterized video games. SER works by dynamically rescheduling shading workloads to raised make the most of GPU sources. There are comparable developments in proprietary ray tracing silicon; doubling the ray-triangle intersection effectivity, a brand new opacity micromap engine that doubles the velocity of “ray tracing of alpha check geometry”, and a micromesh engine that “will increase geometric richness with none change.” BVH creation and storage price’. There may be additionally a brand new and extra highly effective Tensor core for AI duties.

A number of extra frames from Nvidia’s GTC stream.

It is also the primary card to assist Nvidia’s DLSS 3, a brand new method that creates completely new frames – basically including interpolated frames between ‘actual’ ones to dramatically enhance body charges. This has a detrimental impact on enter lag, so it is mixed with Reflex to scale back enter lag as a lot as doable. This reduces the load on each the CPU and GPU, so you may see framerate advantages in each CPU- and GPU-limited video games – however the enter lag penalty means it’s going to be much less helpful for aggressive FPS video games, for instance.

Nvidia has proven that Cyberpunk 2077 runs at ~22fps at 4K with RT enabled and DLSS disabled, then at ~100fps with RT enabled and DLSS 3 enabled – an amazing speedup even when this can be a fastidiously chosen demo. The agency additionally performed a video demo of Flight Sim 2020 operating at ~60fps with RT + DLSS disabled and ~135fps with RT + DLSS 3 enabled – good proof that the DLSS 3 method eases CPU limitations.

Portal vs Portal RTX.

Along with upgrading current video games with RTX and DLSS 3, Nvidia introduced a ‘new’ title: Portal RTX. Made 15 years after the unique launch, this remake appears spectacular from the quick teaser trailer. Will probably be launched free of charge to Portal house owners in November. The mod was created in an app that Nvidia calls ‘RTX Remaster’, which helps you to craft mods for all kinds of video games that add textures upgraded with ray tracing and synthetic intelligence – very neat.

Portal with RTX.

Elsewhere, Nvidia has introduced the Racer RTX, a ‘simulated world’ with unimaginable realism – assume marble demos go as much as 11.

It was a powerful presentation from Nvidia and we won’t wait to check each the efficiency and options of the following era. Will probably be fascinating to see if DLSS 3 lives as much as Workforce Inexperienced’s lofty guarantees… and if the efficiency claims are confirmed, it is going to be fascinating to see if these new playing cards will truly be accessible on the marketed costs. We’ll share extra data as we get it!

Right here comes the complete Nvidia RTX 40 sequence in video kind.
