NVIDIA Announces RTX 40 Series With 2X Performance Leap

NVIDIA just unveiled the first of its next-generation GeForce graphics cards: RTX 4080 and RTX 4090.

The RTX 40 series is powered by NVIDIA’s new ‘Ada Lovelace’ architecture, built on TSMC’s 4nm process node. The previous ‘Ampere’ architecture used Samsung’s 8nm process node.

RTX 4080

RTX 4080 is available in two variants; one with 7680 and 12GB VRAM starting at $899, and another with 9728 CUDA cores and 16GB VRAM starting at $1199.

NVIDIA claims even the 12GB variant is slightly more powerful than the prior flagship, RTX 3090 Ti. The company also claims the 16GB variant is twice as fast as the RTX 3080 Ti.

Both RTX 4080 variants will be available some time in November.

 

RTX 4090

RTX 4090 has 16384 CUDA cores and 24GB VRAM, priced starting at $1599.

It achieves 83 teraflops of performance, making it the most powerful gaming GPU in the world.

NVIDIA claims RTX 4090 is twice as fast as the prior flagship RTX 3090 Ti, while drawing the same amount of power.

‘Ada Lovelace’ Architecture

The RTX 40 series is powered by NVIDIA’s new ‘Ada Lovelace’ architecture, which introduces a number of improvements.

Third Generation Ray Tracing Cores enable more than 2x the ray tracing performance over Ampere’s. These new cores also introduce ‘Opacity Micro-Map Engines’ and ‘Micro-Mesh Engines’, two new hardware features to accelerate certain ray tracing workloads. Shader Execution Reordering improves shader performance by up to 2x when using ray tracing, which NVIDIA says improves framerate by 25%.

Fourth Generation Tensor Cores offer up to 5x the FP8 performance of Ampere’s. Combined with the new Optical Flow Accelerator this enables Deep Learning SuperSampling (DLSS) 3.0. Similar to the SpaceWarp and Motion Smoothing reprojection techniques used in VR for years now, DLSS 3.0 can generate synthetic frames to double the output framerate.

Finally the Eighth Generation NVIDIA Encoder introduces support for the AV1 video codec, which has 40% improved quality at the same bitrate and supports HDR (high dynamic range).

If NVIDIA’s claims are true, Ada Lovelace represents one of the largest performance leaps ever seen in a new GPU generation. Will you be buying an RTX 4080 or 4090 for VR, or are you waiting for AMD’s response?
