The top-end part also bumps up the power draw. The second-generation AMD Ryzen desktop processors are open for preorders today. Shipping on April 19th, the new chips start at $199 for a six-core, 12-thread part running at a base of 3.4GHz and a turbo of 3.9GHz; the prices goes up to $329 for an eight-core, 16-thread processor at 3.7/4.3GHz. The second generation increases clock speeds (the previous high-end part had clocks of 3.6/4.0GHz) and makes the processor's turbo boosting smarter. On first-generation parts, the clock boosting could happen to a pair of cores, or all cores together. This meant that if you needed, say, four fast cores, they were constrained to the "all core" turbo speed. On the second-generation chips, that turbo boosting is now available with any number of cores, just as long as there's power and thermal headroom. Workloads with more than two cores, but fewer than all of them, should be able to use more of the available power budget and hence run faster. The new processors are compatible with the first-generation motherboards (though they may need a firmware update to work). AMD is also releasing a new high-end chipset, X470. X470's big feature is "StoreMI," a hybrid disk system that allows volumes to be built that span both SSDs and spinning disks (and even RAM disks) to boost I/O performance. The price chart above also shows the other couple of differences relative to first generation. First, the top-end part now ships with an in-box heatsink/fan. Previously, the high-end part was shipped naked and had to be used with a third-party cooler. Second, the top part has had its power rating increased from 95W to 105W. This shouldn't make much difference to system builders, as they will generally have power and cooling to spare, but it suggests that those higher clock speeds aren't coming for free.
Over the course of last year, AMD did some serious course correction with the release of its Ryzen line of processors, offering up its first real competition to Intels market-dominating power in years. But the underdog chip company isnt stopping there. It has announced its second-generation Ryzen processors for desktops that look to improve on the previous generation and keep the momentum going for AMDs comeback. AMD isnt announcing full details for the new Ryzen chips just yet — those will come on April 19th, the same day they launch — but the company is offering some information along with preorders, which open today. There are four new second-generation Ryzen chips out next week: a pair of eight-core, 16-thread Ryzen 7 models, and two six-core, 12-thread Ryzen 5 chips. Leading the pack is the $329 Ryzen 7 2700X, clocked at 3.7GHz with a boost to 4.3GHz, along with the slightly cheaper and less powerful Ryzen 7 2700, which costs $299 and is clocked at 3.2GHz (with a boost to up to 4.1GHz). For the Ryzen 5 models, theres the Ryzen 5 2600X, which costs $229 and runs at 3.6GHz (with a boost to 4.2GHz) and the Ryzen 5 2600, which costs $199 is clocked at 3.4GHz, which can be boosted to 3.9GHz. All four processors come with an AMD Wraith cooling unit free in the box. Thats different from last years models, which only included them on higher-end chips, so its is a nice bonus. AMD is sticking with its AM4 socket, which means that youll be able to slot the new Ryzen chips on your existing motherboard. The company has also announced a new AMD X470 chipset that will work with the new chips, adding a new AMD StoreMI feature that allows you to combine SSD storage with older hard drives into a single, faster, virtual disk.
