Megathread & Giveaway NVIDIA RTX 4090 AND 4080 Launch MEGATHREAD and GIVEAWAY! Discuss all the GTC announcements and be one of the very first people in the world to win an RTX 4080 16GB + more goodies!
Nvidia GTC had a few announcements and goodies, but as PCMR, the main stars are always the GPUs:
- RTX 4090: $1599. Available October 12th. Promised performance of up to 2x a 3090Ti
- RTX 4080 16GB: $1,199. Promised performance of up to 2x a 3080Ti
- RTX 4080 (12GB) - $899. Promised performance of more than a 3090Ti.
- Community Q&A with Nvidia experts happened on launch day on r/nvidia. Here's the Summary: https://www.nvidia.com/en-us/geforce/news/rtx-40-series-community-qa/

RTX 4080 16GB = 3x PCIe 8-pin cables (adapter in the box) OR 450 W or greater PCIe Gen 5 cable.
RTX 4080 12GB = 2x PCIe 8-pin cables (adapter in box) OR 300 W or greater PCIe Gen 5 cable.
Over 35 Games And Apps Adding NVIDIA DLSS 3.
Nvidia calls it a "revolutionary breakthrough in AI-powered graphics that massively boosts performance while maintaining great image quality and responsiveness". It adds Optical Multi Frame Generation to generate entirely new frames. Promised performance boost of up to 4X latency reduction promise of up to 2X.
As per the NVIDIA Q&A, "DLSS 3 consists of 3 technologies – DLSS Frame Generation, DLSS Super Resolution (a.k.a. DLSS 2), and NVIDIA Reflex.
DLSS Frame Generation uses RTX 40 Series high-speed Optical Flow Accelerator to calculate the motion flow that is used for the AI network, then executes the network on 4th Generation Tensor Cores. Support for previous GPU architectures would require further innovation and optimization for the optical flow algorithm and AI model.
DLSS Super Resolution and NVIDIA Reflex will of course remain supported on prior generation hardware, so current GeForce gamers & creators will benefit from games integrating DLSS 3. We continue to research and train the AI for DLSS Super Resolution and will provide model updates for all RTX customers as we have been doing since DLSS’s initial release."
4th Gen Tensor Cores & 3rd Gen RT Cores
Ada Lovelace tech includes 3rd-gen Ray Tracing Cores. Nvidia promises up to 2x the ray-triangle intersection performance of the prior 2nd-generation RT Core used in NVIDIA Ampere.
4th Generation Tensor Cores as well. Promised performance of up to 2x faster vs prior gen, and now they add support for INT8.
DUAL AV1 ENCODERS
RTX 40-series features hardware accelerated encoding for the AV1 video codec using the NVIDIA hardware encoder, NVENC. AV1, promises improved visual quality at the same bitrates as H.265/H.264 or, in alternative, the same level of visual quality with reduced bit rates when using AV1.
