SMT is similar to the Hyper-Threading technology featured in most (but not all) of Intel's mid-to-high-end Core desktop processors. And, at least from the details we have about the Ryzen 7 and Ryzen 5 chips announced so far, all those chips will feature thread-doubling simultaneous multi-threading (SMT). For one: AMD says all the Ryzen chips will be unlocked for overclocking. AMD says those chips will be available in the second quarter of 2017, with lower-end Ryzen 3 offerings coming in the second half of the year, as well.Ī couple of features on all of these chips set them apart from Intel's competing offerings. So AMD will be offering six-core and four-core Ryzen 5 chips, as well, although pricing on those hadn't yet been announced when we wrote this. Of course, not everyone has the budget (or the need) for a CPU priced at $329 or more. Here's a look at all three Ryzen 7 chips, along with pricing and their basic specs, direct from AMD. All three feature eight cores and 16 threads. The AMD Rylands at the low end of the company's Ryzen 7 three-chip line, with the Ryzen 7 1700X and 1800X sitting above it. But to get a full sense of Ryzen's benefits, as well as where the Rylags behind Intel (spoiler: single-core performance, and 1080p gaming), we'll have to dig deeper and look at some of the benefits of AMD's chipsets and motherboards, as well. AMD is aiming the $329 Rysquarely at the Intel Core i7-7700K, which currently sells for about $350, and intermittently goes on sale for a little less than that.Ĭan AMD's entry-level Ryzen 7 chip take down Intel's mainstream Core i7 flagship, with its latest-gen "Kaby Lake" architecture and higher 4.2GHz-to-4.5GHz clock speed? The fact that AMD brings twice the cores and threads to the CPU matchup as Intel does certainly works in Team Red's favor. When it comes to pricing, the Rydoesn't have nearly the advantage of the Ryzen 7 1800X, a $499 chip that is aimed at (and pretty solidly matches or bests) the $1,050 Core i7-6900K. The Ryhas a TDP of just 65 watts, while the Ryzen 7 1700X and 1800X both have 95-watt TDPs. TDP, a measure of required heat dissipation). The primary benefit that the Rygains for its lower clocks and lack of XFR is a lower thermal design power rating (a.k.a. (We'll explain XFR later, but in essence at this point, it allows some Ryzen 7 chips to clock 100MHz higher if they have a cooler that can keep temperatures low enough). The primary downsides with the Ryover its sibling chips are its lower clock speeds (3GHz to 3.7GHz, base clock to boost clock), and the lack of support for XFR ("Extended Frequency Range") for this chip, indicated by the lack of an "X" on the end of the chip's name. (Opens in a new window) Read Our Intel Core i7-8700K Review The 6950X is a monster chip for serious, highly threaded workloads, but its roughly $1,700 price is enough to put off almost everyone other than well-heeled, very CPU-dependent professionals. The latest E -Series chips are known as "Broadwell-E," and the alpha dog of that bunch is the 10-core, 20-thread Intel Core i7-6950X Extreme Edition. The company's enthusiast-class E-Series chips, meanwhile, have pushed performance limits by adding ever more cores and threads, but at ever-more-outrageous prices. Those gains were gleaned from slightly higher clock speeds and…well, not a whole lot else. On the other side of the CPU-silicon fence, Intel's latest architecture, the 7th Generation Core, or "Kaby Lake" (which is crested at the moment by the Intel Core i7-7700K we tested recently) saw mostly single-digit performance gains over equivalent 6th Generation ("Skylake") chips. AMD's FX CPU architecture (which went under the successive names of "Bulldozer," "Piledriver," and "Steamroller") hasn't been able to match the silicon in Intel's Core i7 chips for quite some years now, going back to the initial release of the AMD FX-8150 in 2011. We've seen little in the way of real excitement in the enthusiast CPU market for a long time. Single-core and 1080p gaming performance lag behind Intel's comparable Kaby Lake chips.
