Intel AMX Performance With The Xeon 678X Workstation CPU
One of the most compelling features for Intel Xeon 6 Granite Rapids alongside MRDIMMs is Advanced Matrix Extensions (AMX) for helping accelerate AI workloads and more. AMX is also found with the new Granite Rapids WS processors and in currently having my hands on an Intel Xeon 678X in the HP Z4 G6i workstation, I ran some benchmarks looking at the AMX performance and power impact for this…
Intel's Xeon 678X workstation CPU, part of the Granite Rapids series, demonstrates impressive performance capabilities with the introduction of Advanced Matrix Extensions (AMX). This innovative feature bolsters AI workloads and other select software, showcasing significant performance gains on compatible platforms such as the HP Z4 G6i workstation.
The Xeon 678X, running on Ubuntu 26.04 with a Linux 7.0 kernel, was tested in a real-world setting to evaluate the AMX benefits and power impact. The test system featured 4 x 32GB DDR5-6400 memory modules, ensuring an optimal environment for assessing the processor's performance capabilities.
Unlike its predecessors with AVX-512, the AMX implementation in the Xeon 678X does not come with substantial power or thermal repercussions, as confirmed by the latest benchmark tests. This makes the Xeon 678X an attractive option for users seeking enhanced performance in AI applications and other demanding workloads without worrying about excessive energy consumption.
