Intel Core i7-11700K 8 Core Rocket Lake CPU Review Published…

The very first suitable overview of a retail Intel Core i7-11700K 8 Core Rocket Lake Desktop CPU has been revealed by Dr. Ian Cutress of Anandtech. The tech outlet managed to get their palms on a person of the retail chips from a maker who possibly broke the NDA like MindFactory and started off to promote the CPUs a entire month right before the official start on the thirtieth of March.

What’s intriguing about these outcomes than the 1 we have witnessed leak out in advance of is that it is centered on the retail sample. The Intel Core i7-11700K is going to be placed towards the AMD Ryzen seven 5800X which is AMD’s quickest eight main supplying based mostly on the Zen three core architecture. The Main i9-11900K will be the leading-pet dog but primarily based on its pricing, it must be competing against the Ryzen 9 5900X with the exact same eight main configuration but better clock frequencies.

The Main i7-11700K functions the similar main configuration as the Main i9-11900K of 8 cores and sixteen threads but comes with lessened clock speeds. The chip is explained to aspect a strengthen clock of 5. GHz on a solitary & four.6 GHz across all of its 8 cores. The CPU will even carry the identical volume of cache so almost nothing has modified but the major variance need to occur from the clocks and power boundaries. This lessen-binned chip will sit at about 225-250W (PL2) limit although the PL1 limit will be standard at 125W. The PL1 ranking has a TAU period of fifty six seconds when the PL2 rating has a TAU length of two.44ms.

It will be exciting to see how Rocket Lake CPUs overclock due to the fact the minute change amongst the Main i9 and Main i7 chips can be get over by a modest overclock. As for pricing, the Main i7 will also be more cost-effective than the Main i9 variant but we never know but how Intel will price its 8 main Rocket Lake-S Desktop CPUs but. There are reviews that Intel could aggressively price the chips at about $400 US for the Main i9 and $300 US for the Main i7 which could prove to be a terrific determination if they really want to go in opposition to AMD’s Zen three dependent areas in the sub-$500 US phase.

Intel Main i7-11700K 8 Core & sixteen Thread Rocket Lake Desktop CPU Benchmarks

The Anandtech take a look at outcomes were carried out on an undisclosed system that could be showcasing a Z590 motherboard. Other exam tools included ADATA’s sixteen GB DDR4-3200 (CL22) memory kit and a Genuine Copper heatsink with dual SST-FHP141-VF lovers. Each the Rocket Lake and Zen 3 CPUs were being examined with the identical memory configurations although Comet Lake was examined with DDR4-2933 & Espresso Lake was tested with DDR4-2666 MHz memory. The take a look at results could be found beneath:

As you can see in the benefits previously mentioned, the AMD Ryzen 5800X is speedier in nearly all of the CPU-distinct overall performance benchmarks that ended up utilized. The only conserving grace for Intel is AVX-512 but that qualified prospects to an unprecedented rise in energy use, making the Rocket Lake Intel Core i7-11700K far extra inefficient than it by now was. Anandtech reviews that the solitary and multi-thread floating-point efficiency sees a 19-19.5% enhance but the integer efficiency has absent up only by an normal of 10%.

Intel Main i7-11700K Rocket Lake Desktop CPU Benchmarks (Gaming):

When it comes to gaming efficiency, the Intel Main i7-11700K lacks seriously towards the AMD Ryzen 7 5800X and even its Comet Lake-centered predecessor. Anandtech tries to demonstrate that the elevated L3 cache cycles could be a purpose for this adverse effectiveness in games. In accordance to our sources, Intel is previously doing work tricky to correct some of these challenges by means of a micro update that was meant to be offered to board associates by mid of March but has considering the fact that been delayed. It is very likely that Intel will take care of some of these cache-linked issues by BIOS updates but which is some thing we have to keep an eye out in the lengthy time period as early assessments of the 11th Gen Desktop CPU lineup will showcase this type of performance.

Lastly, we have the power and temperature facts. At stock out-of-the-box operation, the Intel Main i7-11700K Rocket Lake CPU hits up to 81C with a ability use of 225W. But with AVX-512, it shoots up to 104C and so does the electricity use which hits a stunning max of 290 Watts. It is much more electrical power-hungry than the Ryzen Threadripper CPUs when functioning AVX-512 instructions. So general, we can see that Rocket Lake is heading to be really hot and electric power-hungry and will absolutely require you to commit in a beefy AIO liquid cooler and also a good PSU.

SiSoftware has also posted their possess exam effects of the Intel Core i7-11700K Desktop Rocket Lake CPU and located it to be slower than AMD’s Ryzen seven 5800X, a lot more inefficient than Skylake & ability-hungry as well.

Summary: A prolonged owing improve with fantastic (+forty% improved) functionality: nine/ten

We’ve really been waiting way too prolonged for this – endless Skylake (SKL) derivatives (Gen six, 7, 8, nine and 10) then finally IceLake (ICL) and TigerLake (TGL) but for cellular (ULV) only. RocketLake (RKL) is not really what we expected, as it is not on 10nm litography but “back-ported” to 14nm+++ and also utilizing the more mature ICL cores (not TGL) but at least appropriate with the 400-series (LGA 1200) platform.

With AMD building continuous enhancements with Ryzen (series 2000, 3000 and now 5000), the top finish i9 10900K CometLake (CML) could not really keep up therefore we actually needed a new contender from Intel. We had been also ready for PCIe four. previously supported by AMD 2 generations in the past and by all present day GP-GPUs and NVMe SSDs probably not really needed, but with mass-sector gaming consoles (Sony PS5, Microsoft XBox SS/XS) working with NVMe/PCIe4 storage – it grew to become a bit of an embarrassment for prime-end PCs to lack it.

RocketLake (RKL) i7 (1170K) does not boost number of cores (still 8C / 16T), nor speeds (rated / turbo), but AVX512 + arch advancements (greater caches, TLBs, and many others.) make it about 50% speedier than CFL/CML and with optimisations (and better pace memory) probably bigger. TDP (Energy) is better at 125W and staying however at 14nm RKL will need a lot additional (~155W?) to maintain prime clocks.

Existing 400-sequence boards should really also aid RKL soon after a BIOS update, but obviously no PCIe four. (as we experienced with AMD Ryzen 3000/5000 and 400-collection boards). You will want a 500-series board which is not unforeseen but nonetheless disappointing.

We have not touched on the Iris Gen12 graphics in this write-up which is a *large* update in excess of the truly outdated EV9.x graphics but at this amount (i7+) it is probable that devoted graphics will be employed. As we’ve witnessed with TGL, the G7 ninety six EU variations are very impressive.

Irrespective of the detailed misgivings – it is a fairly considerably powerful update for any individual acquiring now – not a lot point acquiring the old Skylake-based mostly derivatives (e.g. Cometlake) unless of course the price is pretty much reduced. If you have a workload (virtualization?) that requires far more cores, then 10C/20T CML or quite a few-core SKL-X/KBL-X can however make sense.

Count on to see more information on the processors in the coming weeks together with pricing updates on when and wherever you can invest in these chips for your four hundred and five hundred-sequence motherboards.
