The AMD Ryzen 7 3800XT is a desktop processor
with 8 cores, launched in July 2020, at an MSRP of $399. It is
part of the Ryzen 7 lineup, using the Zen 2 (Matisse) architecture
with Socket AM4. Thanks to AMD Simultaneous Multithreading (SMT)
the core-count is effectively doubled, to 16 threads. Ryzen 7
3800XT has 32MB of L3 cache and operates at 3.8 GHz by default,
but can boost up to 4.7 GHz, depending on the workload. AMD is
building the Ryzen 7 3800XT on a 7 nm production process using
3,800 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 7 3800XT, which simplifies
overclocking greatly, as you can easily dial in any overclocking
frequency.
With a TDP of 105 W, the Ryzen 7 3800XT consumes a good deal of
power, so decent cooling is needed. AMD's processor supports DDR4
memory with a dual-channel interface. The highest officially
supported memory speed is 3200 MHz, but with overclocking (and the
right memory modules) you can go even higher. For communication
with other components in the machine, Ryzen 7 3800XT uses a
PCI-Express Gen 4 connection. This processor does not have
integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Ryzen 7 3800XT, 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 is including the newer AVX2 standard, too, but not
AVX-512.
