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. 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:

• CUDA Compute Capability 8.9
• TSMC 4N process (custom designed for NVIDIA) – 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
• NVENC with 8K 10-bit 60FPS AV1 fixed function hardware encoding
• Dropped NVLink support

RTX 4080 12GB naming and pricing controversy

Numerous outlets, prominent youtubers, reviewers and community have criticized NVIDIA on calling the AD104 chip an RTX 4080 instead of RTX 4070 given previous NVIDIA GPU generations. Considering its chip configuration (21% fewer CUDA cores). It's also priced significantly higher than previous xx70 cards, $900 vs. eg. $500 for RTX 3070, i.e. $400/80% more expensive. The AD103 chip also known as the RTX 4080 16GB has a 256 bit bus width which is typically used for xx70 cards, while the AD104 chip known as the RTX 4080 12GB is using a 192 bit bus width which is also typically used for the xx60 cards, reducing the memory bandwidth available to the GPU.

Products

1. Shader Processors : Texture mapping units : Render output units : Ray tracing cores : Tensor Cores
2. The number of Streaming multi-processors on the GPU.
3. Core boost values (if available) are stated below the base value inside (brackets).
4. Pixel fillrate is calculated as the lowest of three numbers: number of ROPs multiplied by the base core clock speed, number of rasterizers multiplied by the number of fragments they can generate per rasterizer multiplied by the base core clock speed, and the number of streaming multiprocessors multiplied by the number of fragments per clock that they can output multiplied by the base clock rate.
5. Texture fillrate is calculated as the number of TMUs multiplied by the base core clock speed.
