Intel’s “secret” Core i9-11900KB uses a definite architecture on the 10nm node

by

WTF?! Sooner or later, Intel secretly released the Core i9-11900KB, i7-11700B, i5-11500B, and the i3-11100B. The B stands for badass consequently of that’s what these processors are: they employ the 10nm SuperFin node, the superior Willow Cove core architecture, and are clocked increased than their popular counterparts.

Okay, perchance B doesn’t stand for badass. It’s the shorthand for BGA, ball grid array. That’s a solderable form of socket, which device that these processors device completely linked to their motherboards and may per chance well’t be pulled out or swapped out, and are out of bounds for enthusiasts and builders. Which is a rattling shame, I utter.

“Intel has partnered with customers drawn to expanding their product portfolio with fanatic, small develop-part desktop designs,” reads Intel’s legitimate line. “The Intel Core i9-11900KB processor is a BGA solution built with queer specifications and performance namely for these designs.”

The B-series is being known as a secret consequently of Intel by no device formally announced them, however their spec sheets are public on Intel’s processor catalog.

And what mighty ravishing spec sheets they are

  i9-11900KB i7-11700B i5-11500B i3-11100B
Cores / Threads 8 / 16 6 / 12 4 / 8
Immoral Clock 3.3 GHz 3.2 GHz 3.3 GHz 3.6 GHz
Turbo Enhance 3.0 4.9 GHz 4.8 GHz 4.6 GHz 4.4 GHz
Thermal Bustle Enhance 5.3 GHz
L3 Cache 24 MB 12 MB
TDP 65 W

In most strategies, the B-series is an upgrade. Your entire chips hold a 65 W TDP, however with the exception of the 11900KB, they’ve got increased dejected clocks and thermal sail enhance clocks. Presumably, that’s an enchancment courtesy of the jump from 14nm to 10nm.

The Core B-series is listed as a Tiger Lake product, which implies that they leverage Willow Cove cores. Willow Cove is the successor to the cell model (known as Sunny Cove) of the Cypress Cove architecture frail by the favored parts. In our checking out, Willow Cove is rather a small faster than Sunny Cove. Most probably the greatest of its employ is the tumble from 20 PCIe 4.0 lanes to perfect 16 PCIe 3.0 lanes.

But let’s circle support, these are Tiger Lake CPUs. These aren’t Frankenstein prototypes. They’re overclocked cell processors.

  i9-11900Okay i9-11900KB i9-11900H
Market Desktop Desktop OEM Pc
Cores / Threads 8 / 16
Immoral Clock 3.5 GHz 3.3 GHz 2.1 – 2.5 GHz
Turbo Enhance 3.0 5.2 GHz 4.8 GHz 4.9 GHz
Thermal Bustle Enhance 5.3 GHz
L3 Cache 16 MB 24 MB
TDP 125 W 65 W 35 w

Theoretically, the 11900KB will flee cooler than the favored 11900Okay whereas being equally like a flash, if not faster. I am angry to behold the small develop part prebuilts referenced in Intel’s assertion consequently of these processors hold some severe doable.
