'''NNP-T 1300''' is a [[training]] [[neural processor]] designed by [[Intel Nervana]] and introduced in late 2019. Fabricated on TSMC [[16 nm process]] based on the {{nervana|Spring Crest|l=arch}} microarchitecture, the NNP-T 1300 has 22 {{nervana|Spring Crest#Tensor Processing Cluster (TPC)|TPCs|l=arch}} along with 55 MiB of scratchpad memory and operates at up to 950 MHz. This chip comes in a PCIe 4.0 [[accelerator card]] form factor and incorporates 32 GiB of [[HBM2]] memory. This NPU exposes 16 {{nervana|Spring Crest#InterChip Link (ICL)|inter-chip links|l=arch}} for scale-out capabilities.

== Peak Performance ==
The NNP-T 1300 has a peak performance of [[peak flops (half-precision)::93.39 TFLOPS]] ([[bfloat16]]).

== Cache ==
{{main|nervana/microarchitectures/spring_crest#Memory_Hierarchy|l1=Spring Crest § Cache}}
* 55 MiB of tightly-coupled scratchpad memory
** 22 x 2.5 MiB/core

== Memory controller ==
{{memory controller
|type=HBM2-2400
|ecc=Yes
|max mem=32 GiB
|controllers=4
|channels=32
|max bandwidth=1.2288 TB/s
}}

== Interconnect Topology ==
The NNP-T 1300 comes in a dual-slot standard PCIe 4.0 card which enables support for only the ring topology. Chips are interconnected using the 16 available {{nervana|Spring Crest#InterChip Link (ICL)|inter-chip links|l=arch}}.

== Die ==
{{main|nervana/microarchitectures/spring_crest#Die|l1=Spring Crest § Die}}
* 27,000,000,000 transistors
* 680 mm² die size
