As we alluded to earlier when talking about AM5, one of AMD’s design goals was to provide more power to Ryzen 7000 chips so that they could go farther into the vf curve and keep their cores running at a higher frequency in MT-heavy workloads. How much of an improvement, in turn, depends on where on the voltage/frequency curve you end up. As a result, the Ryzen 7000 chips enjoy a significant power efficiency advantage versus the Ryzen 5000 chips. These include the 3 variable power rails, SVI3 VRM monitoring, and AMD’s lower-power Infinity Fabric Links. In other words, for the moment TSMC’s 5nm-class nodes are as good as it gets, putting AMD in a great position to take advantage of the benefits.Ĭoupled with this are all of the various platform power improvements that come with AM5 and the new 6nm IOD. Meanwhile TSMC’s competitors are either struggling by delivering less efficient 4nm-class nodes (Samsung), or they’ve yet to deliver a 4nm-class node at all (Intel). Thus far TSMC 5nm (and its 4nm derivative) is proving to be the powerhouse process of its generation, as TSMC’s clients have seen some solid gains in power efficiency and transistor density moving from 7nm to 5nm.

We’ll start with a look at power efficiency, since power consumption plays a huge part in the Zen 4 story at both ends of the curve.īy tapping TSMC’s current-generation 5nm, process, AMD is enjoying the advantage of a full node shrink for their CPU cores. Zen 4 Power: More Efficient, More Power-Hungry There are some important changes here that are allowing AMD to deliver an average IPC increase of 13%, and combined with improvements to enable higher clockspeeds and greater power efficiency for both single-threaded and multi-threaded workloads, no part of AMD’s CPU performance has gone untouched. Instead, Zen 4 is a further refinement of AMD’s Zen 3 architecture, with AMD taking advantage of things like the new AM5 platform and TSMC’s 5nm process to further boost performance. For that, you’ll want to wait for Zen 5 in 2024.
Still, it’s fair to say that AMD’s goal for the Zen 4 architecture has not been a radical overhaul of their core CPU architecture. And while this attention meant that AMD’s collective attention was split between the CPU cores and the rest of the platform, AMD’s CPU cores are far from being ignored here. Now that we’ve had a chance to take a look at the AM5 platform surrounding the new Ryzen 7000 chips, as well as the new IOD that completes the high-end Ryzen chips, let’s dive into the heart of matters: the Zen 4 CPU cores.Īs laid out in previous pages, a big element in AMD’s design goals for the Ryzen 7000 platform was to modernize it, adding support for things like PCIe 5.0 and DDR5, as well as integrating more fine-grained power controls.
