As of late, Intel is taking the wraps off Rocket Lake, officially launching its first new desktop microarchitectures because the release of Skylake, 5.5 years in the past. Our personal assessment might be up later as of late, so imagine this a sneak peek for what’s coming down the pipe.
Rocket Lake keeps the subtle 14nm+++(?) node that Intel has subtle to a replicate sheen. After Intel discovered its 10nm node was once flawed for desktop chips, it determined to proceed updating desktop on 14nm whilst saving preliminary 10nm manufacturing runs for server and pc chips. Intel’s 10nm procedure node was once not on time a couple of occasions, which left the corporate caught on 14nm for for much longer than it ever expected.
Rocket Lake makes use of the Cypress Cove CPU core. It’s a port of the 10nm Ice Lake CPU core that’s been backported for 14nm and redesigned to suit the traits of Intel’s 14nm procedure. The CPU keeps lots of the clock frequency benefits of Comet Lake’s tenth Gen CPUs, however pairs it with what Intel claims is a 1.19x IPC spice up. In that context, Rocket Lake is an incredible success for Intel’s design group. Backporting a design to an older node calls for a reconsider of the design to ensure sign timings and similar efficiency. Kudos to the engineers for development a brand new chip that would pull Intel off the Skylake rock it ran aground on, even with no new procedure node to make use of.
I’ve were given so much I wish to discuss in the case of Rocket Lake later as of late, however I’ll say this prematurely: Should you’ve ever been taken with what it could seem like for Intel to music the similar node, time and again, Rocket Lake on 14nm provides us a gorgeous just right glance. Rocket Lake completely delivers a efficiency development. It additionally delivers an enormous uptick in per-core energy intake. Intel obviously went to the wall in an try to ship greater than single-digit efficiency uplifts, and you’ll see that focal point mirrored within the CPU’s conduct underneath load. The 5800X’s 7nm node shines when put next, as we’ll speak about.
The Core i9-11900K is a aggressive core, a minimum of so far as efficiency is worried, however the potency figures towards AMD display simply how laborious Intel has driven the CPU to get it into this territory. The cooling and thermal necessities are necessary to nail if you wish to run the CPU at most efficiency. Unmarried-threaded efficiency is the most important space of uplift for Rocket Lake, as we in the past anticipated, with extra main points on that time to observe.
