Features

Lenovo Neptune^® - Market-Leading Innovation

Experience the innovation of the ThinkSystem SC750 V4 Neptune^®, utilizing direct warm-water cooling (up to 45°C). This advanced design effectively removes all heat from all components such as CPUs, memory, I/O, local storage, and voltage regulators, maintaining a system devoid of air flow. The use of water for cooling provides superior heat removal compared to air, allowing critical components to operate at lower temperatures. This results in enhanced performance, increased reliability, and higher density, all packaged in a quiet, energy-efficient system.

Superior Performance, Extreme Core Density

Experience the performance of the ThinkSystem SC750 V4 Neptune^®, driven by two Intel^® Xeon^® 6 processors. With Lenovo Neptune water cooling, it operates Intel^® Xeon^® 6900-series at 500W with MRDIMMs and up to 128 cores, all in a compact form-factor. Using the Intel^® Xeon^® 6900P-series with MRDIMMs, it delivers unparalleled memory bandwidth. All this power and efficiency fits into less than a square meter of datacenter space, redefining compact general purpose supercomputing.
