GeForce RTX 40 series

Nvidia's Ada Lovelace-based GPU family with ray tracing and DLSS 3.

GeForce RTX 40 series

The GeForce RTX 40 series is a lineup of consumer graphics cards from Nvidia, following the RTX 30 series. Nvidia announced the series on September 20, 2022, at its GPU Technology Conference, and the first model, the RTX 4090, launched on October 12, 2022. The RTX 50 series, announced at CES, succeeded it on January 30, 2025. These GPUs use Nvidia’s Ada Lovelace architecture, which includes third-generation RT cores for hardware-accelerated real-time ray tracing and fourth-generation Tensor Cores focused on deep learning.

Architectural highlights of Ada Lovelace include CUDA Compute Capability 8.9, a TSMC 4N process (a custom 5 nm design for Nvidia, distinct from N4), and fourth-generation Tensor Cores with support for FP8, FP16, bfloat16, TensorFloat-32 (TF32), and sparsity acceleration. Third-generation Ray Tracing Cores allow concurrent ray tracing, shading, and compute. Shader Execution Reordering is available but requires developer enablement. The architecture features dual NVENC encoders for 8K 10-bit 120FPS AV1 fixed-function hardware encoding, a new Optical Flow Accelerator to assist DLSS 3.0’s AI-based frame generation, and no NVLink support. Display connections include DisplayPort 1.4a and HDMI 2.1. Double-precision (FP64) performance is 1/64 of single-precision (FP32) performance. High-end cards use two eighth-generation NVENC encoders and a fifth-generation NVDEC video decoder.

The RTX 4090 launched on October 12, 2022, at $1,599 US. The 16GB RTX 4080 followed on November 16, 2022, for $1,199 US. Nvidia originally announced an RTX 4080 12GB at $899 US in September 2022, but after media controversy, it was “unlaunched” and released as the RTX 4070 Ti on January 5, 2023, at $799 US. The RTX 4070 arrived on April 13, 2023, at $599 US MSRP. The RTX 4060 Ti launched on May 24, 2023, at $399 US, and the RTX 4060 on June 29, 2023, at $299 US. A 16GB version of the RTX 4060 Ti appeared on July 18, 2023, at $499 US. On January 8, 2024, Nvidia released the RTX 4070 Super at $599, RTX 4070 Ti Super at $799, and RTX 4080 Super at $999, all with higher specs and lower prices than their original counterparts. Production of the RTX 4080 and RTX 4070 Ti ended due to the Super series, but the RTX 4070 remained.

Lore & Background

The GeForce RTX 40 series was announced on September 20, 2022, at the GPU Technology Conference and launched on October 12, 2022, starting with the RTX 4090 at $1,599 US. The 16GB RTX 4080 followed on November 16, 2022, for $1,199 US. An originally announced RTX 4080 12GB at $899 US was 'unlaunched' after media controversy, then released as the RTX 4070 Ti on January 5, 2023, at $799 US. The RTX 4070 launched April 13, 2023, at $599 US MSRP, followed by the RTX 4060 Ti on May 24, 2023, at $399 US, and the RTX 4060 on June 29, 2023, at $299 US. An RTX 4060 Ti 16GB arrived July 18, 2023, at $499 US. On January 8, 2024, Nvidia released the RTX 4070 Super at $599, RTX 4070 Ti Super at $799, and RTX 4080 Super at $999, with higher specs and lower prices than original counterparts, leading to discontinuation of the RTX 4080 and RTX 4070 Ti. In August 2024, a variant of the RTX 4070 with GDDR6 at 20Gbps was introduced. The architecture includes CUDA Compute Capability 8.9, fourth-generation Tensor Cores with FP8, FP16, bfloat16, TF32 and sparsity acceleration, third-generation Ray Tracing Cores with concurrent ray tracing, shading and compute, Shader Execution Reordering, dual NVENC with 8K 10-bit 120FPS AV1 encoding, a new Optical Flow Accelerator for DLSS 3.0 frame generation, no NVLink support, DisplayPort 1.4a and HDMI 2.1, and FP64 performance at 1/64 of FP32.

Reader's Guide

The RTX 4090 received praise for its performance, with reviewers noting it as among the best graphics cards and capable of native 4K gaming with ray tracing. Its 24GB VRAM and AV1 encoding were highlighted for content creators. However, it faced criticism for its $1,599 price, power consumption at 450W TDP, and massive cooler sizes on aftermarket models, with some being 4 PCIe slots tall and comparable in size to a PlayStation 5. The RTX 4080 received mixed reviews; while it outperformed the RTX 3090 Ti and showed power efficiency with an average draw of 271W, its $1,199 price was criticized as a dramatic increase from the RTX 3080, and sales were weak amid a global cost of living crisis. The RTX 4070 Ti received mixed reviews, praised for thermal and 1440p performance but criticized for weak 4K performance and high price. The RTX 4070 was praised for efficiency and 1440p/4K performance, though later compared unfavorably to AMD's Radeon RX 7800 XT in rasterization and VRAM. The series' significance lies in its introduction of Ada Lovelace architecture features including DLSS 3 frame generation and AV1 encoding, while its pricing and value drew scrutiny against AMD's RDNA 3 competitors.
