Intel 11th-Gen Tiger Lake APU Details Incl. Core Architecture, GPU Cores, Fabrication Tech, DDR5 Memory Support Leak Indicating Performance Boost Over Ice Lake

The Intel Tiger Lake CPUs would be one of the biggest evolutionary leaps for the company. The 11th-Gen CPU lineup is expected to bring powerful performance to the laptop, notebook, and portable computing segment. This generation is expected to bring with it a new chip architecture and several new features. A massive leak regarding the Intel 11th-Gen Tiger Lake APU offers some very important details about the CPUs or APUs.

Intel is expected to announce its 11th generation of mobile computing solutions, the Tiger Lake APUs. The new generation will reportedly offer greater CPU and GPU performance, scalability for different workloads, increased memory and fabric efficiency, advances in security, and many more consumer-centric features. Let’s look at the details which include Core Architecture, GPU Cores, Fabrication Tech, DDR5 Memory Support, etc.

Intel Tiger Lake APUs Fabricated On 10nm Node SuperFin Architecture Packing Willow Cove CPU and Xe GPU Cores:

The 11th-Gen Intel Tiger Lake APUs will be fabricated on an enhanced version of the 10nm FinFET process node. The technology is being called 10nm Enhanced SuperFin architecture. The process features a redesigned transistor (SuperFin) and capacitor design (Super MIM). This is essentially an intranodal architecture which is claimed to provide a performance uplift comparable to a full-node transition.

Intel is confident that its 10nm SuperFin process will be able to match or even exceed TSMC’s 7nm process node. AMD is relying on the TSMC’s 7nm Node to fabricate the ZEN 2-based AMD Ryzen 4000 ‘Renoir’ APUs for laptops. The SuperFin design essentially leverages the refined FinFET architecture to offer improved gate process, additional gate pitch, and enhanced expiation source/drain. Additionally, Intel claims the 10nm Enhanced SuperFin architecture can offer additional performance, interconnect innovations, and optimization for data centers.

The 11th-Gen Intel Tiger Lake APUs will feature the Willow Cove Architecture, which is the second architecture based on the 10nm process node. It was preceded by the Sunny Cove Architecture, which is used in the 10th-Gen Ice Lake CPUs. Needless to add, a new generation always promises a significant boost in IPC gains, which in this case, is claimed to be in the double-digits. Additionally, the Willow Cove cores feature a brand-new cache design with 1.25 MB of L2 cache and 3 MB of L3 per core.

The Willow Cove Architecture should feature much higher frequencies than Sunny Cove cores and that too at lower voltages. This translates into higher Clock Speeds even at lower TDP profiles. This was evident from the Core i3-1115G4 which reportedly features a Base Clock of 3 GHz.

While the Willow Cove Cores will take care of computing, the new Intel Xe ‘Iris’ Gen12 Graphics Chip is reportedly twice as fast as the Gen11 iGPU onboard the 10th-Gen Ice Lake APUs. The Intel Xe graphics architecture will feature 96 Execution Units or 768 Cores along with 3.8 MB of L3 cache.

Intel 11th-Gen Tiger Lake APUs I/O Support Specifications And Features:

The 11th Gen Tige Lake APUs will be based on a dual coherent fabric for interconnect. This means the processors are designed with high bandwidth operations as a priority. The Tiger Lake CPUs will support LPDDR5-5400, LPDDR4X-4667 & DDR4-3200 MHz memory which translates to 86GB/s of bandwidth. Needless to mention, this makes the Tiger Lake CPUs the first x86 mobility CPU platform that supports the next-generation DDR5 memory.

The Tiger Lake APUs will also feature Thunderbolt 4 and USB 4 support. Intel is also assuring PCIe Gen 4.0 support with a full 8 GB/s link provided to the memory interface. Each port has a bandwidth of up to 40 Gb/s. The Xe-LP architecture display engine onboard the Tiger Lake APUs can reportedly handle 4K resolutions at 30 FPS, but Intel is planning to enhance the same to 4K at 90 Hz.
