Intel 12th Gen Alder Lake Desktop & Mobility CPUs To Offer Up To 20% Single-Thread Performance Increase & Twice The Multi-Threaded Uplift

An official Intel 12th Gen Alder Lake CPU slide has been leaked by Videocardz which confirms the next-gen desktop & mobility lineup offering up to 20% single-threaded performance increase. The Intel 12th Gen Alder Lake CPUs are expected to launch in the second half of 2021, replacing Intel's 11th Gen Rocket Lake Desktop and Tiger Lake Mobility chips.

In its official slide, Intel calls the Alder Lake a 'Breakthrough CPU Architecture. The company claims that its 12th Gen processors will offer a 20% single-threaded performance uplift and a 2X uplift in multi-threaded tasks. The Intel Alder Lake CPUs will be the first CPUs fabricated on the brand new 10nm Enhanced SuperFin process node which is a refined and more optimized version of the 10nm SuperFin process node used to manufacture the current Tiger Lake CPUs.

It is not explicitly stated which processor family Intel is comparing its performance uplift to but a recent rumor stated that Alder Lake CPUs will offer a 20% IPC uplift over Tiger Lake so it is likely that Intel is talking about Tiger Lake with Willow Cove here which makes sense rather than making comparisons against Rocket Lake with Cypress Cove or older Haswell based offerings.

Following are some of the updates you should expect from Intel's 2021 architecture lineup:

Intel Golden Cove (Core) Architecture:

Intel Gracemont (Atom) Architecture:

Intel highlights some of the key features of its Alder Lake CPUs in the slide too such as the use of a hybrid core design which would include both Golden Cove cores (successor to Willow Cove) & also the Gracemont cores which are the next-generation Atom architecture. The Golden Cove cores will serve as the big cores on the CPU & will feature simultaneous multi-threading support while Atom cores will stick to a non-SMT design. Some brand new features for the cores themselves will include Hardware-Guided Scheduling, Design Optimizations, and Energy-aware core parking.

When it comes to I/O, the Intel 12th Gen Alder Lake CPU lineup will feature both PCIe Gen 5 & PCIe Gen 4 support, Intel WiFi 6E (Gig+), and Thunderbolt 4 support. For memory, Alder Lake CPUs will come with a wide array of options ranging from DDR5/DDR4 for the desktop platform and LPDDR5 / LPDDR4 for the mobility platform. Moving forward, Intel will also add in LPDDR5X support in its Alder Lake refresh line of processors known as Raptor Lake which you can find more details over here.

When it comes to the desktop platform, the Intel Alder Lake Desktop CPUs will feature support on the brand new 600-series platform which would include the Z690 motherboards. The motherboard will carry the LGA 1700 socket which is designed around Alder Lake and future generation CPUs. It also looks like only the flagship Z690 motherboards will be able to support DDR5 memory with native speeds of up to 4800 MHz whereas cheaper motherboards based on mainstream & budget-tier chipsets (H670, B650, H610) will retain DDR4-3200 support.

In addition to that, Intel Alder Lake CPUs will feature 16 PCIe Gen 5.0 and 4 PCIe Gen 4.0 lanes. The chipset will offer Gen 4 and Gen 3 lanes although the exact amount of lanes is currently unknown. As for the rest of the features for 600-series chipset motherboards, you can see them below:

The package size for the chips is 45.0 x 37.5 mm whereas the existing LGA 1200 package is 37.5 x 37.5 mm. We also know that the Intel Alder Lake CPUs will come with a max core configuration of 16 cores and 24 threads (8 cores / 16 threads based on Golden Cove & 8 cores / 8 threads based on Gracemont). Expect more information by Intel in its upcoming events which are scheduled for 23rd March.
