Amazon solidifies push into custom chips that replace Intel and AMD processors, unveils Graviton4 and Trainium2 cloud servers

Amazon on Tuesday introduced two of its new processors, which will be used exclusively by its Amazon Web Service (AWS) division. The two new system-in-packages are the Graviton 4 processor for general-purpose workloads and the Trainium 2 processor for artificial intelligence training. The new devices will power AWS instances that will provide supercomputer-class performance to Amazon clients. 

Graviton4

Amazon’s Graviton4 — the company’s 4th Generation general-purpose processor that competes against AMD EPYC and Intel Xeon CPUs — continues to use Arm’s 64-bit architecture and packs 96 cores. The processor is said to showcase up to 30% higher compute performance, a 75% increase in memory bandwidth compared to its predecessor, Graviton3. AWS did not disclose whether its Graviton4 relies on Arm’s Neoverse V2 cores, but this is a likely scenario.

Like the AWS Graviton3, the AWS Graviton4 relies on a multi-chiplet design composed of seven tiles. Keeping in mind that AWS has worked with Intel Foundry Services over packaging, this is expected. It is not completely clear which foundry produces silicon for the Graviton4.
