With a little judicious undervolting it was also running pleasingly cool, and without getting too testy in terms of power draw. Again I got very little change out of bumping up the clocks on our 11600K sample, though I was at least able to get a solid 4.9GHz all-core setting. That's likely why overclocking is such a struggle with Rocket Lake. That right there is the main compromise of this 14nm back-port. The Rocket Lake i5 by comparison hits 130W, and actually considerably more if you push it in multithreaded workloads. The 7nm Zen 3 architecture is seriously efficient, and that is able demonstrated by the chip's peak wattage of just 76W. The only place where there is a significant delta between the Core i5 11600K and the Ryzen 5 5600X is when it comes to power. Something to bear in mind if you're chasing frequency numbers for the hell of it, and something to definitely check on after you enable your XMP settings in the BIOS. With that standard setting the 11600K achieves memory bandwidth of 41.65GB/s, but if you switch to Gear 2 that drops by a third to just 27.67GB/s.
INTEL CORE I5 2450M OVERCLOCKING PRO
Memory: Corsair Vengeance RGB Pro 32GB DDR4-3200īut as Intel's chips have been capable of running up to 3,200MHz with the original 1:1 ratio (and was always above rated spec in our testing) that's what our CPU benchmarks are running with. Intel motherboard: Asus ROG Maximus XIII HeroĪMD motherboard: Gigabyte X570 Aorus Master Suffice to say, this is a more than capable gaming processor that won't stand in the way of your graphics card's ability to render its silicon butt off.

It's also almost up there in comparison to Intel's i9 11900K too. In gaming, the i5 11600K is generally capable of offering practically identical performance to the 5600X, give or take a few frames per second here and there. As a mainstream six-core CPU, the Core i5 11600K is pointing itself directly at AMD's equivalently specced Ryzen 5 5600X, and here the benchmark battle across the board is a far more even contest. And while it does so from a raw frame rate perspective the actual relative processing performance, platform, and value proposition of the top Rocket Lake chip falls far behind what the Ryzen 9 5900X and Ryzen 7 5800X can offer.īut this is far more like it. The main aim of the flagship Core i9 11900K was to retake the lead at the top of the gaming CPU market, to push ahead of the AMD Ryzen competition for better or worse. (Image credit: Future) How does the Intel Core i5 11600K perform? That extra performance is the upside, the downside is that you lose the areal and efficiency benefits the smaller 10nm node offers, resulting in a bigger, hotter, and more power hungry chip. That all means you're getting a hefty IPC increase of some 19 percent over the previous desktop CPUs, as well as some smarter silicon to go along with the vagaries of Intel's PCIe 4.0 support. There are fewer execution units (EUs) inside the desktop version (32 vs 96), but honestly that's of little consequence to gamers who will be jamming a discrete GPU alongside their new processing silicon. Intel has also dropped in the Xe GPU architecture that debuted within its latest Tiger Lake mobile processors. Intel's desktop chips have been stuck on slight iterative updates of the 14nm Skylake core design released in 2015, but for this 2021 launch it has pulled the 10nm Sunny Cove design out of its last-gen Ice Lake mobile CPUs and back-ported that into its mature 14nm production process. Maybe that's not a deal-breaker right now, but with the dropping prices of PCIe 4.0 SSDs it's going to be the connection of choice going forward.īut with Rocket Lake this is more than simply a higher-clocked version of the Comet Lake i5, it's actually a whole new architecture. That doesn't change the fact that Intel's 500-series motherboards don't themselves support it from the chipset, and that reduces the effectiveness of the platform as a whole.

The ups and downs in our performance testing with the 11th Gen CPUs, however, do make us think this could be down to teething problems surrounding Intel's inaugural PCIe 4.0 platform. We've not had the greatest experience with PCIe 4.0 performance from the Rocket Lake chips so far, neither from the top-end Core i9 or this i5 11600K. It's also got that PCIe 4.0 support baked into the CPU itself, though sadly not throughout the new Z590 chipset.

But the all-core figure of 4.6GHz (which you do see solidly in multithreaded workloads) and the 4.9GHz single-core number are both one step higher than the Comet Lake i5. The Core i5 10600K has a nominally higher 4.1GHz base, but you never really see that in use anyway. The only point it doesn't is in the almost irrelevant base clock figure of 3.9GHz.
