AMD released some additional information about its upcoming Ryzen chips at CES this calendar week. Having spent over four years designing the architecture, the company plans to continue it around for at least that long. That'southward according to CTO Mark Papermaster, who was on-hand to hash out the chip. First things first — AMD is promising a hard launch for Ryzen, without any paper launches, limited availability, or limited product introductions. When Zen debuts it'll debut in multiple (still unknown) configurations, not a single viii-cadre function.

As PCWorld details, Papermaster as well confirmed the four-year target and emphasized that information technology didn't mean AMD wouldn't iterate the core. "We're not going tick-tock," Papermaster said. "Zen is going to exist tock, tock, tock."

There are several ways to read this sentence. Tick-tock refers to Intel's previous practice of introducing new CPU architectures in one product cycle and new manufacturing nodes in the other. AMD has never strictly deployed an equivalent approach over multiple product cycles. I wouldn't necessarily conclude that Papermaster is saying AMD won't deploy Zen on new manufacturing nodes over fourth dimension, but that AMD intends to implement an aggressive serial of tweaks and improvements to the current core as time goes by.

There'due south a pregnant lag betwixt when a blueprint tapes out and when it ships to consumers. This means AMD'south CPU blueprint team is most certainly difficult at work on Zen's successor already, fifty-fifty though Zen hasn't actually shipped nevertheless. While I can't make any concrete predictions about how Zen will compete against specific products in Intel's lineup, the demos nosotros've seen and the product information already available has convinced me that Ryzen will exist at least a meaningful and meaning improvement on AMD's overall ability efficiency, performance, and performance-per-watt. With Intel'south CPU performance largely stuck and performance gains relegated to unmarried-digit increases yr-on-year, there's a great bargain of excitement for Ryzen. Even if information technology doesn't seize the pole position from every price signal, there'due south pent-up demand for potent parts at practiced pricing. AMD wants to capitalize on that, and the best manner to practise so is to keep delivering core improvements year-over-year.

I recollect we can reasonably look forward to that. The first Ryzen APUs are probably going to be DDR4-based, but in that location's no reason for AMD not to push into HBM2 equally that standard becomes more affordable. Power consumption and efficiency volition continue to exist important targets in years to come because AMD is unlikely to match Intel clock-for-clock and core-for-cadre with its very kickoff launch. Ryzen is the showtime of AMD'southward comeback, not the stop of information technology, and setting a iv-yr target for the architecture now makes sense. It besides gives AMD fourth dimension to recall about what it wants to come adjacent. Intel'due south Kaby Lake debut this week didn't do much to excite the enthusiast community, but we'll accept a much improve sense of how the two chips compare once we get a picayune closer to Ryzen'south still-unspecified (Q1) launch date.

Overclocking features, Crossfire

Meanwhile, PCWorld's Brad Chacos reports on some interesting news on the overclocking front. All AMD Ryzen CPUs will exist unlocked and overclockable, but merely three motherboard chipsets — X370, X300, and B350 will take overclocking support. If current rumors are accurate, that corresponds to the upcoming enthusiast-class chipset (X370), mainstream (X300), and minor course gene (X300) chipsets. That's well-nigh of the chipsets AMD is launching (most of the non-budget ones, at least) and should cover virtually the unabridged overclocking market. AMD motherboards take historically been cheaper than their Intel counterparts, so this shouldn't be a major effect.

31 AM4-Stack

Crossfire and SLI support volition only be implemented on the X370, however. Co-ordinate to AMD, the relative handful of people who apply multi-GPUs always use higher-terminate motherboards. Practically, this makes sense, since nearly people can't beget or don't want a second bill of fare, and if you do desire i, you tin can probably afford a slightly more expensive motherboard. Given the typical toll gap between AMD and Intel nosotros don't see this being a major issue, either.
