History
PredecessorGeForce 30 series

The GeForce 40 series is a family of graphics processing units developed by Nvidia, succeeding the GeForce 30 series. The series was announced on September 20, 2022 at GTC 2022 GeForce Beyond A Special Broadcast at GTC event and are expected to start shipping on October 12, 2022.[1] The cards are based on the Ada Lovelace architecture and feature hardware-accelerated raytracing (RTX) with Nvidia's third-generation RT cores and fourth-generation Tensor Cores.

Details

Architectural highlights of the Ada Lovelace architecture include the following:[2]

  • CUDA Compute Capability 8.9[3]
  • TSMC 4N process (custom designed for NVIDIA)[1] – not to be confused with N4
  • Fourth-generation Tensor Cores with FP8, FP16, bfloat16, TensorFloat-32 (TF32) and sparsity acceleration
  • Third-generation Ray Tracing Cores, along with concurrent ray tracing, shading and compute
  • Shader Execution Reordering - needs to be enabled by the developer[4]
  • NVENC with 8K 10-bit 60FPS AV1 fixed function hardware encoding[5][6]
  • A new generation of Optical Flow Accelerator to aid DLSS 3.0 intermediate AI-based frame generation[7]
  • No NVLink support[8]

Products

  • Double-precision (FP64) performance of the Ada Lovelace chips are 1/64 of single-precision (FP32) performance.
  • All the cards feature GDDR6X video memory.

  5. ^ Texture fillrate is calculated as the number of texture mapping units (TMUs) multiplied by the base (or boost) core clock speed.

RTX 4080 12GB naming and pricing controversy

Numerous outlets, prominent YouTubers, reviewers, and the community have criticized Nvidia on calling the 12GB RTX 4080 using the AD104 chip an RTX 4080 instead of RTX 4070 given previous Nvidia GPU generations and the large gap in specifications and performance.[11][12][13][14] Unlike other cases of the same-named product with differing memory configurations that were otherwise very close in performance, the 12GB RTX 4080 uses a completely different chip and configuration (27% fewer CUDA cores and other related hardware,[clarification needed] along with the cut down 192 bit memory bus width which was typically used for the xx60 cards[citation needed]). This leaves it up to 30% slower than the 16GB RTX 4080 in raw performance without even considering the VRAM difference, which is indicative of an entirely different tier of performance and should entail a different name. The community[who?] has speculated that because it's priced significantly higher than previous xx70 cards, $900 vs. eg. $500 for RTX 3070, i.e. $400/80% more expensive, that could be a factor in why Nvidia decided to give it the RTX 4080 name.[citation needed]

Aftermath and "unlaunching"

On October 14, 2022, Nvidia announced that due to the confusion caused by the naming scheme, it would be "unlaunching"—i.e. pausing the launch of—the 12GB RTX 4080, with the 16GB RTX 4080's launch remaining unaffected. It is currently unclear on if or when the product will be rebranded or when the product will launch.[15][16]
