That means running the processor cores at stock settings paired with overclocked memory could offer roughly equivalent performance gains in some workloads. Given that we overclocked our memory in tandem with activating PBO, it's possible some of those slim gains actually stem from increased memory performance. AMD also cites using PBO to boost performance, but in our test environment, that doesn't have a dramatic impact on performance. Instead, you should look to tuning the Infinity Fabric and memory, which both raise in lockstep to a sweet spot of DDR4-3600. That's an added value that you should take into consideration, but you might need a beefier cooling solution if you plan on pushing the limits with overclocking.įor now, we don't see massive gains in performance for the 3800X from the automated overclocking features, and AMD says we shouldn't expect too much manual overclocking headroom. You'll lose access to the PCIe 4.0 interface in exchange for lower pricing, but you'll also have a compelling upgrade path in the future.ĪMD's Ryzen 7 3800X comes with a bundled cooler while competing Intel processors come with a cardboard box. Motherboard partners continue to offer X470 motherboards, and they are cheap and plentiful. Unfortunately, the faster interface does result in higher-priced X570 motherboards, but AMD's continued support for the X470 motherboard ecosystem could help blunt the blow. That's an advantage that Intel can't match. The extra throughput doesn't equate to improved performance in gaming, but it does speed up everyday tasks like file transfers and will unlock more performance in storage-bound applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.AMD's platform also supports the PCIe 4.0 interface that provides twice the throughput of the previous-gen standard. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Hardware virtualization is available on the Ryzen 7 3800X, which greatly improves virtual machine performance. This processor does not have integrated graphics, you will need a separate graphics card. For communication with other components in the machine, Ryzen 7 3800X uses a PCI-Express Gen 4 connection. The highest officially supported memory speed is 3200 MHz, but with overclocking (and the right memory modules) you can go even higher. AMD's processor supports DDR4 memory with a dual-channel interface. With a TDP of 105 W, the Ryzen 7 3800X consumes a good deal of power, so decent cooling is needed. You may freely adjust the unlocked multiplier on Ryzen 7 3800X, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. AMD is building the Ryzen 7 3800X on a 7 nm production process using 3,800 million transistors. Ryzen 7 3800X has 32MB of 元 cache and operates at 3.9 GHz by default, but can boost up to 4.5 GHz, depending on the workload. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. It is part of the Ryzen 7 lineup, using the Zen 2 (Matisse) architecture with Socket AM4. The AMD Ryzen 7 3800X is a desktop processor with 8 cores, launched in July 2019, at an MSRP of $399.
