The Core i9-11900 K is Intel’s flagship offering in their brand-new Rocket Lake-S desktop CPU series. Previously today we evaluated another brand-new Rocket Lake processor, the mid-range Core i5-11600 K and discovered it to be a good offering. At the MSRP it’s not competitive enough with the Ryzen 5 5600 X, with that AMD CPU presently overpriced, we felt the finest 6-core alternative for those purchasing right now is in fact the older 10 th-gen Core i5-10600 K, or even much better, the $20010600 KF design which is easily offered.

So while a bit frustrating, total the 11600 K did reveal strong gains over its predecessor for efficiency work and a really little enhancement in video gaming efficiency. We intentionally avoided the 10900 K for our day-one protection as the 10600 K simply appeared like the more sensible item and it stood an opportunity versus its Ryzen competitors.

Normally it’s the flagship CPU getting the headings, however honestly, the Core i9-11900 K at a sale price of $540(in 1,000 system amounts) and an existing market price of $615 at locations like Newegg, just does not stand a possibility. We saw that beginning paper, then the pre-release evaluations validated it. Due to the fact that you’ll desire to understand where it stands, here we are. Needless to state, it’s not a fun time to purchase high-end computer system parts.

Even at $540, we do not understand why this CPU exists, this is something you’ll comprehend as soon as we enter into the benchmark charts. Intel themselves have actually confessed in a current AMA that they started deal with 11 th-gen Core processors in Q1 2019, and maybe didn’t anticipate Ryzen efficiency to scale in addition to it did when they transferred to 7nm. The 12- core, 24- thread Ryzen 9 5900 X costs $550, although schedule has actually been miserable for that part, the efficiency deficit is going to be quite unsightly in the majority of tests.

If you missed our previous protection going over the prices and specs of these brand-new 11 th-gen Core processors, here’s a fast refresher …

Core i9-11900 K Core i7-11700 K Core i9-10900 K Core i9-10900 KF Ryzen 9 5900 X
Rate (MSRP) $539 $399 $488 $472 $549
Existing Retail $615 $420 $460 $420 $550

L3 Cache 16 MB 20 MB 64 MB
iGPU Design UHD Graphics 750 UHD Graphics 630 N/A
TDP 125 watt 105 watt

Unlike the 10- core/20- thread Core i9-10900 K, the 11900 K is an 8-core, 16- thread part loading a 16 MB L3 cache and a 125 watt TDP. In spite of including less L3 cache and less cores the sticker price has actually increased from $490 to $540 That’s a 10%cost walking for 20%less cores.

Definitely, it’s a little bit more complex than that as the 11 th-gen architecture is totally various to the 10 th-gen series that came prior to it. Rocket Lake is a brand-new architecture, or rather a hybrid architecture that backported Ice Lake’s 10 nm Sunny Cove cores, for this reason the codename modification to Cypress Cove.

This makeshift service appears completely unneeded at present. All Intel required to do was keep costs of their 10 th-gen lineup where they presently are– damaging AMD Zen 3 parts– and our company believe they might have offered well. Intel simply required to make the rate cuts main and we ‘d alter our CPU suggestions appropriately.

Rather, the 11900 K is a more complicated CPU that’s more pricey to produce and in lots of methods even worse. This is even more complicated once you understand that Intel’s real next-gen CPU is best around the corner and it must be far better.

The 12 th-gen Core series codenamed ‘Alder Lake’ is anticipated in late 2021, and with it we need to see Intel shift to a 10 nm procedure on the desktop, while likewise embracing a brand-new LGA 1700 socket and other innovations like DDR5.

That holding true, why release Rocket Lake? Why launch brand-new Z590 motherboards that will not support the 12 th-gen parts coming later on this year? You can inform I’m not keen on this release and the Core i9-11900 K will not be getting my suggestion, however instead of ending the evaluation here, let’s take a look at the outcomes so you can get the complete image.

For checking the Intel CPUs I utilized the Gigabyte Aorus Z590 Master utilizing BIOS variation F5a, the board was set up with 32 GB of DDR4-3200 CL14 double rank, dual-channel memory, and cooling was supplied by the Corsair iCUE H150 i Elite Capellix White. All this hardware was set up in a Corsair 5000 D Air flow case and powered by the RM850 x power supply. The Ryzen test system includes the Gigabyte X570 Aorus Master motherboard, utilizing the very same cooler, memory and power supply.

For this evaluation we’re looking specifically at outcomes for Intel CPUs that aren’t power minimal, so no TDP minimal screening. This is generally how we check Intel CPUs, as this is likewise how most of Z490 and Z590 boards run out of package. While we’ll be utilizing the default clock multiplier tables, none of the Intel CPUs are sticking to any power limitations.

All efficiency criteria were ran utilizing a GeForce RTX 2080 Ti, then we changed to an RTX 3090 for the video gaming tests.


Right off the bat, we’ll inform you we prepare to avoid a part of our efficiency tests as the outcomes are quite uninteresting. The 11900 K is slower than the 10900 K while costing more, so it’s not a terrific CPU option for workstation and efficiency loads. The Cinebench R20 multi-core outcomes sum it up well. When compared to the previous gen 8-core part, the 10700 K, the 11900 K looks excellent as it increases efficiency by 20%.

However the brand-new 8-core part isn’t priced to change the 10700 K, however rather the 10900 K and because compare it was 8%slower, a remarkable effort for a CPU with 20%less cores, however likewise not remarkable provided the cost.

The genuine concern for the 11900 K though is the Ryzen 9 5900 X, which is a tremendous 42%much faster in this test. That’s no little margin and you definitely would not anticipate both CPUs to inhabit the very same cost point based upon that.

When taking a look at single core efficiency we see that the 11900 K is 14
