Amazon keeps the pressure on Intel, AMD with 192-core Graviton5 CPU

re:invent Amazon on Thursday unveiled Graviton5, its densest, highest performance CPU yet, cramming 192 processor cores into a single socket and promising new levels of AWS performance.

Since they first launched in 2018, the Graviton chips have become a mainstay of AWS's compute offering. For the past three years running, Amazon claims that Graviton accounted for more than half of all new CPU capacity.

With Graviton5, capacity is in ample supply with 192 Arm Neoverse V3 cores fabbed on TSMC's 3nm process tech. Those cores are backed by a larger 192MB L3 cache, which helps to cut down on cache misses and improves performance by reducing the amount of data that needs to be fetched from slower DRAM. The chip also features an improved memory subsystem that boosts speeds to 7200 MT/s, with support for 8800 MT/s DIMMs in the works.

Combined, Amazon says its ...
