![]() ![]() Each small 3900X compute chiplet, referred to as a CCD (Core Chiplet Die), comes with eight physical cores spread across two four-core Core Complexes (CCXes). We'll provide extensive power and efficiency testing on the following pages to get a more accurate picture of actual power consumption.Īs pictured here, the 39000X comes packing AMD's Zen 2 microarchitecture spread across two small 7nm eight-core compute chiplets tied together with the Infinity Fabric interconnect via a larger 12nm I/O die (IOD). We can chalk that up to different measurement techniques. ![]() You'll also notice the Core i9-9900K, known for its high power consumption and intense heat generation, has a lower 95W TDP than the 3900X's 105W rating. AMD hopes to offset that advantage with its increased IPC throughput and the 3900X also supports the PCIe 4.0 interface with twice the bandwidth of the -9900K's PCIe 3.0 interface. The -9900K comes with four fewer cores and eight fewer threads than the 3900X, marking a distinct difference in the price you pay per thread, but the -9900K does hold the clock speed advantage. But both company's HEDT chips are much more expensive than the 3900X and require pricey HEDT motherboards.īack in the familiar realm of the mainstream desktop, Intel's $488 Core i9-9900K serves as the 3900X's primary competitor. That processors has its own advantages, like access to 64 lanes of PCIe 3.0, and like the -9920X, it supports quad-channel memory. ![]() There's no doubt the 3900X also blurs the line between the AMD's own HEDT Threadripper platform and the mainstream desktop: The Threadripper 1920X is AMD's only core-comparable processor. ![]() Intel's Core i9-9920X slots in with 12 cores and 24-threads for $1,199, a $700 premium over AMD's Ryzen 9 3900X. We have to reach up to Intel's high end desktop (HEDT) platform to find a fair comparison based on core counts. Make no mistake - from a core count perspective, the $500 12-core 24-thread Ryzen 9 3900X really has no comparison on the mainstream desktop. Pair that with the lower per-core pricing and the debut of the PCIe 4.0 interface for the desktop, and the Ryzen 3000 series appears to be a potent force. AMD even added support for auto-overclocking for mainstream processors. All of the models also come with beefy stock coolers, solder thermal interface material between the heat spreader and die to improve thermal transfer, and unlocked multipliers for easy overclocking. The Ryzen 7 3700X is particularly impressive with its combination of price and performance putting it squarely among the best gaming CPUs.ĪMD is staying true to its enthusiast-friendly roots: Although you can pair the Ryzen 3000 chips with the new X570 chipset, they are also backward compatible with most AM4 socket motherboards. If you're looking for something even beefier, AMD also recently released the 16-core Ryzen 9 3950X, which has taken our best CPU list by storm.Īside from those halo parts, AMD also has plenty of models that address the bulk of casual users, gamers, and enthusiasts, like the eight-core 16-thread Ryzen 7 3700X we also have in the lab, and a lineup of six-core 12-thread Ryzen 5 models. Paired with the advantages of the 7nm process and more cores, not to mention AMD's trailblazing of the PCIe 4.0 interface on desktop platforms, the Ryzen 3000 chips promise an explosive step forward in performance.ĪMD's first chips to come packing TSMC's 7nm process span the entire range of the mainstream desktop stack, but push core counts up from eight cores to 12 cores and 24 threads with the Ryzen 9 3900X we have in the lab today, upsetting the status quo and bringing mainstream platforms into what used to be the realm of the pricey high end desktop. After the company's sophomore effort with the second-gen Ryzen processors, which featured a faster process paired with the same first-gen Zen design, the company is plowing forward with its Zen 2 architecture that AMD says offers up to 15% more instructions per cycle (IPC). At the time, AMD laid out a roadmap that included a steady cadence of tick-tock-like updates interspersed with new revisions of the scalable microarchitecture. AMD paved the way for the 'Matisse' Ryzen 3000 series several years ago when it unveiled the revolutionary chiplet-based Zen microarchitecture. ![]()
