Technical slides reveal new truths about Ryzen's power management

Ever since AMD announced the new Ryzen processors in early December, there has been a steady stream of information leaks, alleged benchmarks, and even a handful of possible stock keeping units a few days ago. So it should come as no surprise that a handful of slides have made their way onto the web going more in-depth with AMD’s latest and greatest.

In fact, it appears most of the presentation is uploaded on the Japanese site PC Watch despite the fact that none of the information was intended for the public, at least yet. There is a lot to parse through there and a lot of it is overly technical, but at least a few slides may have implications on the end-user experience.

Notably, AMD takes the time to compare the new Zen core with an unnamed-but-probably-Intel competing chip. Not only does the Zen die come in at a slightly smaller footprint than the competitor, which is also 14nm, but it manages to squeeze in L2 cache much more efficiently.

There is also some information on the way the Zen chips handle heat and power. Through a combination of more than 1,300 path monitors, 48 power supply monitors, 20 thermal diodes, and nine droop detectors, the chip is constantly gathering massive amounts of data. This usage data can be flipped back around and used for identifying stronger cores, providing perfect power to every part of the chip, and pushing clock speeds to their absolute maximum.

There are some other interesting facts stashed away among the slides. The Zen architecture will adopt simultaneous multithreading, a more traditional multi-tasking process akin to Intel’s Hyper-Threading. Per-core voltage and frequency control appear to be platform-wide features and despite a huge possible voltage range, all chips carry a 3.4GHz or higher base clock speed.

While it is always good to take leaks and rumors with a grain of salt, it is hard to see much benefit in leaking fake processor technicalities. We are also close enough to an alleged release that this sort of information should be making its way to possible partners and engineers. These modern features should help accelerate the hype on an already promising release and, if they are true, we’ll know soon enough.

AMD Ryzen 7000: availability, pricing, specs, and architecture
A group shot of Ryzen 7000 CPUs.

AMD's Ryzen 7000 CPUs are here, and there are plenty of them to go around. AMD started out strong by introducing the best processors in the Zen 4 lineup, including the flagship Ryzen 9 7950X, and then followed up by launching even more CPUs. Now, the Ryzen 7000 family includes a whole host of desktop and mobile CPUs, and even the 3D V-Cache versions of AMD's chips.

We've already had the chance to test some of AMD's latest and greatest, and with more to come, we've kept our ears to the ground to not miss any details about the latest AMD CPUs. Here's everything we know about Ryzen 7000.

AMD’s Ryzen 7000 lineup is confusing, but at least we get a sticker

AMD's latest laptop CPU range is huge, and the lineup covers not just Zen 4 processors. In fact, buying a laptop with a Ryzen 7000 processor could mean you're getting a Zen 2, Zen 3, Zen 3+, or Zen 4 chip.

Because the naming scheme is so confusing, it's easy to imagine that less inquisitive consumers might feel a little lost. AMD seems to have found a way to remedy this, but is this really the perfect solution?

This is how you can accidentally kill AMD’s best CPU for gaming

It turns out that one of AMD's best gaming CPUs, the Ryzen 7 5800X3D, can accidentally be killed if you try to overclock it, and it's all because there are no limitations as to how far you can push the processor.

Igor Wallossek of Igor's Lab found that the software used for overclocking and overvolting Ryzen CPUs currently doesn't impose any limits when you try to ramp up the voltage. And that's a recipe for turning a fun performance boost into an overclocking nightmare.
