The AMD Ryzen 9 7900 is a desktop processor with 12 cores, launched in January 2023, at an MSRP of $429. It is part of the Ryzen 9 lineup, using the Zen 4 (Raphael) architecture with Socket AM5. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 24 threads. Ryzen 9 7900 has 64 MB of L3 cache and operates at 3.7 GHz by default, but can boost up to 5.4 GHz, depending on the workload. AMD is building the Ryzen 9 7900 on a 5 nm production process using 13,140 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. You may freely adjust the unlocked multiplier on Ryzen 9 7900, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 65 W, the Ryzen 9 7900 consumes typical power levels for a modern PC. 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 computer, Ryzen 9 7900 uses a PCI-Express Gen 5 connection. This processor features the Radeon Graphics integrated graphics solution. Inside the box you will not only find the processor, but also a Wraith Prism cooler.
Hardware virtualization is available on the Ryzen 9 7900, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will 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.
