The AMD Ryzen 5 6600U is a mobile processor with 6 cores, launched in January 2022. It is part of the Ryzen 5 lineup, using the Zen 3+ (Rembrandt) architecture with Socket FP7. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 12 threads. Ryzen 5 6600U has 16 MB of L3 cache and operates at 2.9 GHz by default, but can boost up to 4.5 GHz, depending on the workload. AMD is making the Ryzen 5 6600U on a 6 nm production node, the transistor count is unknown. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. The multiplier is locked on Ryzen 5 6600U, which limits its overclocking potential.
With a TDP of 15 W, the Ryzen 5 6600U consumes very little energy. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 4800 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Ryzen 5 6600U uses a PCI-Express Gen 4 connection. This processor features the Radeon 660M integrated graphics solution.
Hardware virtualization is available on the Ryzen 5 6600U, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
