Nvidia Ampere Nvlink
Nvidia is helping professionals address these challenges and tackle enterprise workloads from the desktop to the data center with the new nvidia rtx a6000 and nvidia a40.
Nvidia ampere nvlink. The nvidia ampere gpu architecture is nvidia s latest architecture for cuda compute applications. With ampere we think nvidia is adding pam 4 which adds two bits per signal and at 25 ghz gives each nvlink 3 0 lane the same 25 gb sec bandwidth bi directionally as nvlink 2 0 but it only requires half the number of signal pairs as nvlink 2 0 to give the same 50 gb sec of bandwidth per port. In addition to the trio of new gpus the flagship geforce rtx 3080 the geforce rtx 3070 and the ferocious geforce rtx 3090 huang introduced a slate of new tools for geforce gamers. This provides significant performance gains for graphics workflows like 3d model development and compute workflows like desktop simulation for computer aided engineering cae.
The cards also support a single nvlink connector now up to nvlink 3. The third generation of nvidia high speed nvlink interconnect implemented in a100 gpus and the new nvidia nvswitch significantly enhances multi gpu scalability performance and reliability. Ampere is the codename for a graphics processing unit gpu microarchitecture developed by nvidia as the successor to both the volta and turing architectures officially announced on may 14 2020. With more links per gpu and switch the new nvlink provides much higher gpu gpu communication bandwidth and improved error detection and recovery features.
It is named after french mathematician and physicist andré marie ampère. The nvidia ampere gpu architecture retains and extends the same cuda programming model provided by previous nvidia gpu architectures such as turing and volta and applications that follow the best practices for those architectures should typically see speedups on the nvidia a100 gpu without any. Built on the nvidia ampere architecture the gpus feature new rt cores tensor cores and cuda cores that accelerate graphics rendering compute and ai significantly faster than previous generations. The first professional visualization card to be launched based on nvidia s new ampere architecture.
Today s nvidia ampere launch is a giant step into the future he added. The nvidia ampere architecture builds upon these innovations by bringing new precisions tensor float tf32 and floating point 64 fp64 to accelerate and simplify ai. The final ampere architectural feature that nvidia is focusing on today and finally getting away from tensor workloads in particular is the third generation of nvidia s nvlink.
