12/5/2023 0 Comments Amd ryzen 7 2700x![]() The single Core i9-7900X is provided as a point of reference for the extreme users, and I'm working on a larger CPU roundup article where I'll discuss some of the changes in benchmarks, but everything here is current as of April 2018. ![]() I'm omitting a few processors for now, as testing isn't complete, but all the major current options are present along with most of last year's models, plus a few other extras like the i7-4770K and i7-965XE. That includes the Meltdown and Spectre patches for Windows, which in some cases cause a modest drop in performance. The list of current test platforms and hardware is up and to the right, and I've been retesting all (yes, all!) of my CPUs with the latest drivers, firmware, and applications. ![]() Price is also a factor, though all the X470 boards right now are premium models and are priced accordingly. Initial results show only minor variations in performance, so your motherboard choice will largely come down to features and aesthetics. I have X470 boards from Asus and MSI as well, and I'm going to look at the three main contenders next week. Going from DDR4-2400 to DDR4-3400 can improve overall system performance by 10 percent or more, depending on the application.įor this review, I've tested the Ryzen 7 2700X and other Ryzen processors using Gigabyte's Aorus X470 Gaming 7 WiFi board. What's important to note is that AMD gets more help from higher RAM clocks than Intel, because on Ryzen the RAM clock also sets the speed that's used for all communications between various CPU elements, the chipset, memory, and more. ![]() I used the A-XMP profile and the Gigabyte and MSI boards both ran that speed without any difficulties. AMD shipped a kit of G.Skill Sniper X DDR4-3400 CL16 memory for use with the Ryzen 7 2700X and Ryzen 5 2600X (which I'll be reviewing separately, though the numbers are in the charts here). One thing worth going over again is the memory speed. I'm also using stock cooling, where applicable. This is good news in that you get nearly maximum performance with no effort, and the Ryshould be the better choice for overclocking (it's cheaper and has lower starting clockspeeds), but today I'm looking at stock performance. The Ryzen 7 2700X runs at close to 4GHz with every workload I've tested (3925MHz minimum), and sacrificing the benefits of AMD's SenseMI and Precision Boost 2 for a gain of only 275MHz doesn't strike me as particularly important. I'll be looking more at overclocking next week, but in practice I've found overclocking of the latest Intel and AMD processors-especially the top models like the 2700X and 8700K-is becoming less important. AMD says all-core overclocks of 4.2GHz are typical, and the Ryzen Master overclocking software has been improved to allow per-CCX module clockspeed adjustments, but it's still a bit more limited than Intel's approach where you can set clockspeeds by CPU core usage. I'll be taking a detailed look at StoreMI in the coming week or two, to see how it fares compared to pure SSD storage as well as Intel's Optimus Memory.Īs with all previous Ryzen processors, the Ryzen 7 2700X is fully unlocked. SSD capacities up to 256GB are supported (for the StoreMI cache), another 2GB of DRAM can be used for an even faster cache, and the main data drive can be up to 32TB. It's free, it works with any storage device, and it provides smart SSD caching of your hard drive. The other change isn't something I've had time to test just yet, but AMD now has StoreMI as a value-added feature for X470. That's a big deal, considering a few of the processors previously wouldn't do more than DDR4-2800. AMD has improved the power infrastructure on the chipset, and I was able to run every single Ryzen CPU in my possession with DDR4-3400 CL16 memory without a hitch on the X470 boards. The opposite is also true, and existing motherboards with a BIOS update will all support the Ryzen 7 2700X and other new Ryzen processors. First is what hasn't changed, which is great compatibility: all the X470 motherboards continue to use socket AM4 and are backward compatible with existing Ryzen CPUs. Finally, let's quickly talk about the X470 platform changes.
