Intel 11th Gen ‘Rocket Lake’ Desktop CPUs Launched, Including Flagship Core i9-11900K

Intel 11th Gen

Something to look ahead to: Intel has formally announced eleventh-gen Core “Rocket Lake” computing device processors these days, and a lot of those new elements are coming in at extra low cost fee factors than AMD’s equal Ryzen 5000 CPUs. Is it time to get enthusiastic about new Intel CPUs?

Today we’re placing the very last pieces of the puzzle collectively on Intel’s eleventh-gen computing device CPU collection ahead of opinions later this month. In the lead as much as this release, Intel had already given up quite a piece of statistics on Rocket Lake, plus the loopy move of leaks we’ve received over the previous couple of months that culminated in real evaluations of retail Core i7-11700K processors beforehand of the actual declaration.

We recognise the design is still built on their 14nm procedure, however it features a brand new core structure codenamed Cyprus Cove. This is Intel’s Ice Lake design at the beginning destined for 10nm, backported to 14nm, bringing with it as much as a 19% IPC development compared to Skylake and its derivatives during the last five years. However it’s now not the contemporary middle design from Intel, with Tiger Lake – really on 10nm – the usage of a era more moderen structure in mobile gadgets.

Intel 11th Gen Specs

Intel had formerly told us approximately the Core i9-11900K and the inclusion of a most of eight CPU cores. There’s a brand new Xe included GPU internal, new AI functions, and new platform assist via Intel’s 500 series motherboards. This is all stuff we’ve mentioned on already so permit’s reduce to the chase with the total listing of processors and pricing.

While there are plenty of person processors listed in this table – a long way too many in my view – the fundamentals of Rocket Lake are cut up up into 3 series: Core i9, Core i7 and Core i5, as standard. However unlike previous generations, there are no Rocket Lake Core i3 fashions, Intel is alternatively launching refreshed tenth-gen parts at the decrease cease which we’ll talk approximately quickly.

Intel 11th Gen

The Core i9 and Core i7 parts are very similar: all % 8 CPU cores and sixteen threads with 16MB of L3 cache. The K fashions are unlocked SKUs that help overclocking, the F models do no longer characteristic incorporated portraits, and the T models are low strength versions with a 35W TDP. The fashions that do feature an iGPU use new Xe portraits, even though that is being branded as UHD Graphics 750 for some purpose. You’ll find 32 execution units here with as much as a 50% overall performance enhance in comparison to preceding generations in line with Intel.

With the Core i9 and Core i7 parts the usage of the equal fundamental format, what separates them? The fundamental answer is frequency. The Core i7-11700K and KF are clocked up to five GHz on a single middle, and up to 4.6 GHz all-middle. The Core i9-11900K and KF push the unmarried-middle Turbo as much as five.3 GHz, however that’s with Thermal Velocity Boost, a function that will increase clock speeds while operating temperatures are low, and this selection isn’t enabled on Core i7. Without TVB, the 11900K still tops out at five.2 GHz, an boom on the 11700K, but the all-core frequency is simply 100 MHz higher at 4.7 GHz.

The different difference among the Core i9 and Core i7 elements is hidden in the footnotes of the SKU list. The 11900K and KF both function through default the usage of “DDR4-3200 Gear 1”, at the same time as all of the other SKUs, which include the Core i7 range, default to DDR4-3200 Gear 2.

These Gears check with the frequency ratio among the memory controller and reminiscence itself, which has traditionally been 1:1 on Intel elements. Gear 1 is the same old 1:1 ratio, while Gear 2 is a 2:1 ratio, halving the memory controller frequency. This manner that while the unlocked Core i9 processors run at a popular 1:1 ratio, the locked Core i9 parts and the Core i7 line all use a slower 2:1 configuration through default.

This introduces a few in addition differentiation among the Core i7 and i9 parts because the i7 models may have worse reminiscence performance. You may be familiar with those ratios in case you’re an AMD Ryzen person given that the advice for the ones elements as nicely is to run in a 1:1 ratio, instead of pushing memory frequencies better and falling again to two:1. So it will be thrilling to see how this affects Intel processors.

With that stated, motherboard producers are likely to ignore this advice and run all Rocket Lake processors in Gear 1 (so a 1:1 ratio) out of the field. AnandTech showed this was the behavior they saw when checking out their retail Core i7-11700K processor: it need to run at 2:1 happening Intel’s slides, however the actual default seen inside the motherboard was 1:1.

Let’s communicate pricing for these parts earlier than searching on the Core i5 line. The maximum thrilling thing to word is the pricing of the unlocked Core i7 models: $374 for the KF and $399 for the K SKU the usage of Intel’s trendy tray pricing version. It ought to be referred to that tray pricing for bulk devices is not similar to an MSRP, and generally at launch Intel’s elements are bought at 10% above this tray fee or thereabouts, before falling to or underneath the listed charge within the months after.

In any case, what we are searching at is an eight center, 16 thread Rocket Lake CPU priced round $four hundred, that’s undercutting AMD’s 8-middle Ryzen 7 5800X that retails for $450. There may be a few other platform charges to take into account, like the difference in motherboard pricing, however in the beginning look that is an aggressive price factor from Intel that have to compete strongly with AMD’s offering. If these costs are correct, then Intel could be offering better overall performance per dollar inside the eight middle area for the reason that early 11700K critiques display it acting near the extent of a 5800X.

Intel 11th Gen

SKU for SKU, these Core i7 elements are barely more expensive than remaining-gen offerings: about $25 extra than the Core i7-10700K and KF happening Intel’s tray price. However those new elements are speculated to be quicker, and they’re still cheaper than AMD’s line proper now.

What doesn’t make as an awful lot feel is the rate of unlocked Core i9 models. $539 for the 11900K and $513 for the 11900KF represents a $one hundred forty premium over the Core i7 models for what amounts to a very small frequency bump. The 11900K will emerge as competing with AMD’s Ryzen 7 5900X at around $550, despite the fact that AMD is imparting 12 cores versus Intel’s 8. Moreover, the 11900K is probably to present a performance regression in core-heavy programs compared to the 10900K, given the step back from 10 cores to eight cores.

Intel seems to be interested in capturing die-difficult fanatics and fanatics with that kind of pricing model, that is in comparison to the 10th-gen Core i9 collection that did provide first rate performance gains over the Core i7s in a few workloads. The clear standout within the eleventh-gen series is the Core i7 component.

With the Core i5 line, Intel is likewise trying to be very competitive inside the mid-variety.

All CPUs are six cores with 12 threads, 12MB of L3 cache and for the parts with an iGPU, the identical UHD Graphics 750. The K parts are unlocked, while clock speeds also vary between the tiers. The pinnacle-end elements do up to four.6 GHz all-middle and 4.Nine GHz single center, whilst a lower-cease SKU like the Core i5-11400F does four.2 GHZ all-center and 4.4 GHz single-center.

Pricing keeps to undercut AMD. The 11600KF should end up around $260 at retail from a $237 tray charge, setting it beneath AMD’s Ryzen five 5600X at $three hundred – and compared to 10th-gen Core i5s there is no price growth. But the actually compelling products look like the decrease-tier elements, especially the Core i5-11400F at a $157 tray rate, probable around $a hundred and seventy-a hundred and eighty at retail. AMD doesn’t have anything compelling in this fee tier proper now, with the Ryzen 5 3600 selling for $2 hundred or even the Ryzen five 2600 going for $190.

With the 11400F the use of Intel’s new Rocket Lake structure which should supply a healthful overall performance bump, we ought to have multiplied competition inside the $150 to $2 hundred CPU marketplace and it’ll make it harder for AMD to justify selling a three-12 months-old CPU at the sort of excessive fee. We’ve already been recommending Intel’s Core i5 CPUs in this segment for months and if there’s no adjustment on AMD’s facet, that’s set to continue with Intel launching faster models.

As for Core i3 and Pentium Gold processors, Intel aren’t releasing eleventh-gen alternatives simply yet, instead refreshing their tenth-gen Comet Lake offerings. These are primary frequency bumps, so something just like the Core i3-10100 is now clocked 100 MHz better and becomes the Core i3-10105 on the same price.

Intel has been speakme approximately Rocket Lake’s CPU features for some time, so we’ll simply breeze through this in case you neglected it. Aside from the brand new Core architecture, another most important addition is the bump from 16 PCIe 3.Zero to 20 PCIe four.0 lanes from the CPU. This lets in you to attach both a x16 GPU and a x4 SSD without delay to the CPU for pleasant overall performance, in assessment to preceding designs in which M.2 SSDs had to undergo the chipset. Intel also are ultimately coming to the desk with PCIe four.0, bringing feature parity with AMD.

We also get a higher media encode-decode engine way to the improve to Gen 12 photos and all that comes with it, despite the fact that this capability received’t be available with F collection SKUs.

11th-gen processors aid a extensive variety of progressed overclocking features. One of the maximum exciting ones is real-time memory frequency overclocking, on the way to permit tweaking reminiscence OCs in Windows through Intel’s Extreme Tuning Utility with none restarts. Previously you’d need to do maximum reminiscence overclocking within the BIOS. Intel additionally provides a much wider variety of AVX offsets and controls, which is specifically beneficial given these new processors support AVX-512 and overclockers will likely need to set a massive offset to get a solid OC.

New Intel 500 series motherboards are launching alongside Rocket Lake, too. The principal features are memory overclocking support on H570 and B560 motherboards, a new x8 DMI for double the bandwidth between the CPU and chipset, and full help for PCIe four.Zero throughout the road-up. These forums are backwards compatible with 10th-gen processors as well.

However you don’t want a 500 collection board to use an eleventh-gen processor, as Rocket Lake is well suited with some 400 series forums, namely Z490, H470 and Q470. Unfortunately, B460 and H410 forums do not guide Rocket Lake as they use an incompatible chipset. Intel tells us that depending on the motherboard, you can get PCIe four.Zero aid and the entire 20 CPU lanes of PCIe on four hundred series forums with Rocket Lake CPUs, however this could come right down to whether or not the motherboard supplier allows it and their board format.

We’ll wrap up with a short examine Intel’s overall performance slides, which aren’t very useful as they’re restricted inside the facts proven – and we already have actual evaluations of the Core i7-11700K on the internet if you want to peer an unbiased analysis. Intel shows just 4 games in their gaming comparisons, all benchmarked with a GeForce RTX 3080.

Intel is displaying “massive overall performance,” which to them approach eight to 14% development versus the Core i9-10900K in these four games. Up against the Ryzen nine 5900X, Intel is also winning in their benchmarks, with a 3 to 11% lead. Intel also expects the Core i5-11600K to be quicker than the Core i5-10600K through 7 to 16% within the equal 4 video games they have showcased.

Intel’s different benchmarks surround productiveness overall performance, and prefer previous displays a number of the focus is on packages coded to take specific advantage of Intel’s accelerators. It’s doubtful whether or not, for example, the video introduction and MLPerf gains shown right here versus the 5900X might additionally apply to the Core i9-11900KF, which does no longer consist of the integrated GPU.

The key piece of statistics of modern-day assertion changed into pricing, which gives context to the performance and specifications we already knew about – specifically performance for the 11700K. The new Rocket Lake CPUs are anticipated to head on sale on March 30th, that is when reviews may even go live and if all is going well availability should not be a problem for Intel parts as we discussed in our CPU and GPU availability and pricing replace in advance this week.
