Intel just recently took the wraps off their "Beast Canyon" NUC 11 platform at Computex 2021, and for those in the know, replacing Ghost Canyon was no simple task. To do it, Intel has deployed some ingenuity using their compute element that was first introduced with 8th Generation processors several years back. They have also opened up the chassis to 7 liters using a more familiar form factor similar to chassis like the NR200 from Cooler Master; this allows for a customizable platform that supports full-size GPUs and SFX power supplies.

Alongside the 11th Gen compute element, the NUC 11 Extreme has enough room for consumers to deploy a full-size graphics card up to 12" in length and dual-slot. This means cards from the RTX 30 series and Radeon 6000 series with standard cooling will fit without issue, while cards with custom cooling will need more attention.

There are several SKUs coming to market for NUC 11 Extreme; our sample is based on the NUC11BTMi9 in the charts above. Additional SKUs include the NUC11BTMi7 that includes the 11700B i7 Processor compute element.

Additionally, the 11th Gen Compute Element will be available separately in the SKU in the second image above.

Specifications and Marketing

Specification for our sample gives us the 11th Gen Core i9 compute element with the 11900KB CPU; this is a 65W 8-core 16 thread processor with a base clock of 3.3GHz and TVB of 5.3GHz built on Intel's 10nm SuperFin node.

Our SKU is outfitted with 16GB of DDR4-3200 from HyperX but support ramps all the way up to 64GB of memory for those wanting to max it out. Storage is deployed over 4x m.2 slots; one supporting Gen4, our sample had a Rocket NVMe 4 installed from the factory.

I/O includes Thunderbolt 4 with two ports on the rear of the unit alongside eight USB 3.2 Gen 2 ports, Wi-Fi 6e, and 2.5Gbe via the Intel i225 chipset.


The Intel NUC11 Extreme is expected to cost around $1150 for the Core i7 SKU, while the Core i9 should rest somewhere around $1350. The individual compute elements should have MSRPs at $780 and $980, respectively.

Cinebench, Realbench and AIDA64


Cinebench is a long-standing render benchmark that has been heavily relied upon by both Intel and AMD to showcase their newest platforms during unveils. The benchmark has two tests, a single-core workload that will utilize one thread or 1T. There is also a multi-threaded test that uses all threads or nT of a tested CPU

Intel NUC 11 Extreme Beast Canyon Review 30 | TweakTown.com

We put the NUC 11 Extreme alongside our previously tested 11th Gen NUC platforms. The core count being doubled clearly gives a win to the Extreme, but single-thread performance shows a substantial increase with 11900KB over other Tiger Lake parts. Multi-thread shows a peak of 12265.


Intel NUC 11 Extreme Beast Canyon Review 31 | TweakTown.com

Realbench uses both video and photo workloads to benchmark your CPU. In these scenarios, the Extreme was much quicker than the previous, pulling in 21.5 seconds for Image Editing, 29.5 for Encoding, and 37.6 seconds for Multi-Tasking.

AIDA64 Memory

Intel NUC 11 Extreme Beast Canyon Review 41 | TweakTown.com

I installed a few games on the Extreme while I had in under a testing. Far Cry New Dawn managed to give us an average frame rate of 121 FPS, high settings 1080p, while Horizon Zero Dawn with the ultimate quality preset pushed 102 FPS at 1080p. Moving to 1440p, our configuration handled it with 74 and 88 FPS, respectively, while 4K proved a bit much for the RTX 3060.

Thermals and Final Thoughts


Intel NUC 11 Extreme Beast Canyon Review 44 | TweakTown.comIntel NUC 11 Extreme Beast Canyon Review 43 | TweakTown.com

Above, we have two thermal images from the unit. The first is in its idle state, where temps approach 38c at the top of the chassis. The second is during a gaming session, the fan has ramped up slightly in this scenario, and we see the heat being pushed out the top at 41c.

Final Thoughts

Just when I thought NUC 11 would get no better than the Enthusiast platform reviewed back in March, NUC 11 Extreme is now on our desk and having gone through testing; quite possibly the best NUC Intel has ever designed. It surpasses Ghost Canyon by default with the IPC of 11th Gen Intel Tiger Lake and form factor redesign to allow discrete GPUs up to 12"; this means cards all the way up to the RTX 3080Ti will fit, though it's wise to watch power requirements going to this level.

System performance for the 11900KB is quite amazing. Its single-thread performance is on par with Rocket Lake desktop variants like our 11700K, while its support for PCIe Gen4 means Intel can deploy drives like the Sabrent Rocket 4 to unleash its full potential. Paired with a discrete GPU, our sample having the RTX 3060 from ASUS, this machine becomes a gaming beast, easily handling 1080p gaming with well over 100 FPS in titles we tested like Horizon Zero Dawn and Far Cry New Dawn while 1440p is certainly an option as well.

We don't typically discuss upgradability when it comes to NUC platforms, but Intel has left the door wide open on the Extreme; the compute module itself can handle three m.2 solutions and 64GB of memory at 3200MHz while also supporting XMP while external connectivity has been taken to extremes as well with two Thunderbolt 4 and eight USB 3.2 ports. The only grip I may have with this platform might be its lack of USB-C on the front panel.

What We Like

Form Factor: NUC 11 Extreme offers a familiar form factor with 7L chassis!

Connectivity: Solid connectivity that includes Thunderbolt 4 and USB 3.2.

Price: Fair pricing considering performance.

What Could Be Better

Front Panel: Would like to see better options on front panel.











The Bottom Line

Intel's NUC 11 Extreme is easily the best ever designed, and its barebones price isn't too bad on the wallet either!
