NVIDIA Announces the new GeForce RTX 4090 and GeForce RTX 4080

Through its digital presentation from the GTC, the Californian company NVIDIA has introduced its new generation of graphics cards, the GeForce RTX 4090 and GeForce RTX 4080, which promise up to 4 times higher performance than the RTX 30X generation thanks to the new DLSS 3.0.

NVIDIA ADA LOVELACE Architecture

The new chip behind the new GPUS, built with a 4-nanometer process, 46 billion transistors and a G6X micron memory, will enable a new way of processing data with capacities of up to 90 Shader TFLOPS and twice the efficiency. This will also integrate the third generation of RT cores with capacities of up to 200 RT TFLOPs and up to 2x faster Ray-Triangle intersections. It will also feature the fourth generation of Tensor Cores with capabilities of up to 1,400 Tensor TFLOPS and an optical flow accelerator.

The new technology behind Ray Tracing

This new generation of graphics cards adds a new technology called Shader Execution Reordering, which is able to re-schedule processing on the fly, something that will speed up the Ray Tracing process by up to two or three times.

DLSS 3.0

The new version of NVIDIA's Deep Learning Super Sampling now integrates new processes. In DLSS 2.0 for example the GPUS scaled from 1080p resolution to near 4K super resolution. With DLSS 3.0 the super resolution will be transformed into sequential 4K frames and with an optical accelerator, as well as a flow accelerator, it will generate several frames to have a more realistic image within a low latency workflow. In other words, this new technique seeks to improve some of the flaws that were found in the previous technique, especially in high-resolution images with high speeds. Another benefit of this new technology is that in games that demand more from the CPUs, such as those with too many physics calculations or open worlds, DLSS 3.0 allows the GPU ADA to render them at a higher frame rate than the CPU itself allows. It is important to underline that this technology will be available on October 12 and will currently only be compatible with the new GeForce RTX 40.

The new GeForce RTX 40x

The GeForce RTX 4090, which will arrive on October 12, will be up to four times more powerful than the GeForce RTX 3090 Ti and will integrate 24GB of G6X memory and will have a suggested retail price of $1,599. On the other hand, the GeForce RTX 4080 will be up to four times more powerful than the 3080 Ti and will have 16GB of G6X memory and will have a suggested retail price starting at $1,199 depending on the model. Something that surprised is that there will be some GPUs with 12GB of G6X memory that can cost up to $899 dollars. The latter will be launched in November 2022.

New games with RTX

One of the surprising announcements is that Portal has been developed with RTX by NVIDIA Lightspeed Studios, who used Omniverse to remaster it as if it were a mod. This title was originally released in October 2007 and was one of GTC's games of the year, now it will be back to showcase the capabilities of DLSS 3.0 as a completely free DLC for PC owners of the game.
