AMD announces Zen 5 and the Ryzen 9000 series, with a 16% IPC uplift shipping in July

It's been less than two years since the Zen 4 CPU architecture was launched but progress waits for nobody; today at theevent AMD announced its new Zen 5 design. The new Ryzen 9000 series of desktop processors will ship in July with an average IPC uplift of 16% compared to their predecessors.

You can see more detail about the specific changes that deliver this ~16% IPC bump in my Zen 5 architecture dive but suffice it to say, while they look quite minor on paper, they're actually pretty significant. AMD is adamant that Zen 5 is"not a trivial update" and that it is, in fact,"a sweeping update." We'll know for sure once the independent reviews come in, of course.

What isn't clear at this point is what process node the CCDs are being manufactured on—still over at TSMC's foundries, so it will be either N5 or N4—but it is interesting to note that the default TDP limits for the lower-spec 9000 chips arelower than their Zen 4 equivalents. Whether that means they'll be easier to overclock is another matter, but it is good to see power limits going down, rather than up, for a change.
