![]() We're impatiently awaiting new firmware revisions to gauge how they react, but we have tested a multitude of PBO configurations with the Ryzen 7 3800X, of which there are many potential options, with varying levels of success. 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. That opens up much more aggressive boost behavior, on both single and multiple cores, that could widen the performance gap beyond what we see on the spec sheet.AMD's platform also supports the PCIe 4.0 interface that provides twice the throughput of the previous-gen standard. The 3700X's PPT tops out at 88W, while the motherboard can pump up to 142W to the 3800X at peak performance. That's a 300 MHz increase in base frequency and a 100 MHz bump to boost clocks, but the real advantage should lay in the higher Package Power Tracking (PPT) envelope, which is a measurement of the maximum amount of power delivered to the socket. The 3800X also comes with a healthy serving of 32MB of 元 cache, while Intel's -9700K comes with 12MB.Īs the higher-priced version of the Ryzen 7 3700X, the 3800X has higher base and Precision Boost frequencies of 3.9 and 4.5 GHz, respectively. In either case, we expect that AMD's 7nm design will continue the trend of heightened power efficiency over Intel's 14nm parts. ![]() The only way to make real power comparisons is via power measurement, which we'll get to shortly. Intel specs TDP at the base frequency, thus ignoring peak heat output during boost activity, while AMD measures with all cores fully loaded. Instead, they measure the amount of heat the chip dissipates under load, but both companies use different test methodologies. Contrary to popular belief, these ratings aren't meant to quantify power consumption. The -9700K comes with a 95W TDP rating, whereas the 3800X weighs in with a 105W rating. ![]()
