AMD Socket AM5
The AMD Ryzen 7 7800X3D is a desktop processor with 8 cores, launched in January 2023, at an MSRP of $449. It is part of the Ryzen 7 lineup, using the Zen 4 (Raphael) architecture with Socket AM5. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen 7 7800X3D has 96 MB of L3 cache and operates at 4.2 GHz by default, but can boost up to 5 GHz, depending on the workload. AMD is making the Ryzen 7 7800X3D on a 5 nm production node using 11,270 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. The multiplier is locked on Ryzen 7 7800X3D, which limits its overclocking potential.
With a TDP of 120 W, the Ryzen 7 7800X3D consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5200 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Ryzen 7 7800X3D uses a PCI-Express Gen 5 connection. This processor features the Radeon Graphics integrated graphics solution.
Hardware virtualization is available on the Ryzen 7 7800X3D, 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 has added support for the newer AVX2 and AVX-512 instructions, too.
