Ampere is the codename for a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to both the Volta and Turing architectures. It was officially announced on May 14, 2020 and is named after French mathematician and physicist André-Marie Ampère.
Nvidia announced the Ampere architecture GeForce 30 series consumer GPUs at a GeForce Special Event on September 1, 2020. Nvidia announced the A100 80 GB GPU at SC20 on November 16, 2020. Mobile RTX graphics cards and the RTX 3060 based on the Ampere architecture were revealed on January 12, 2021.
Nvidia announced Ampere's successor, Hopper, at GTC 2022, and "Ampere Next Next" (Blackwell) for a 2024 release at GPU Technology Conference 2021.
Details
Architectural improvements of the Ampere architecture include the following:
- CUDA Compute Capability 8.0 for A100 and 8.6 for the GeForce 30 series
- TSMC's 7 nm FinFET process for A100
- Custom version of Samsung's 8 nm process (8N) for the GeForce 30 series
- Third-generation Tensor Cores with FP16, bfloat16, TensorFloat-32 (TF32) and FP64 support and sparsity acceleration. The individual Tensor cores have with 256 FP16 FMA operations per clock 4x processing power (GA100 only, 2x on GA10x) compared to previous Tensor Core generations; the Tensor Core Count is reduced to one per SM.
- Second-generation ray tracing cores; concurrent ray tracing, shading, and compute for the GeForce 30 series
- High Bandwidth Memory 2 (HBM2) on A100 40 GB & A100 80 GB
- GDDR6X memory for GeForce RTX 3090, RTX 3080 Ti, RTX 3080, RTX 3070 Ti
- Double FP32 cores per SM on GA10x GPUs
- NVLink 3.0 with a 50 Gbit/s per pair throughput
- PCI Express 4.0 with SR-IOV support (SR-IOV is reserved only for A100)
- Multi-instance GPU (MIG) virtualization and GPU partitioning feature in A100 supporting up to seven instances
- PureVideo feature set K hardware video decoding with AV1 hardware decoding for the GeForce 30 series and feature set J for A100
- 5 NVDEC for A100
- Adds new hardware-based 5-core JPEG decode (NVJPG) with YUV420, YUV422, YUV444, YUV400, RGBA. Should not be confused with Nvidia NVJPEG (GPU-accelerated library for JPEG encoding/decoding)
