Something to look forward to: Intel appears to be on a roll as of late. Fresh off an impressive discussion of long-term chip manufacturing process roadmap, and the debut of its new Intel Arc brand for discrete graphics chips (GPUs) aimed at gamers, the company has provided an equally impressive and comprehensive view of the designs that will be powering these and other future chips at its latest Architecture Day 2021.

Intel talked about a huge range of items, here are the highlights:

Intel launched its Alder Lake processor architecture today, and at their Architecture Day 2021 event the company explained that the processor was specially optimised for Windows 11.

Windows 11 for the first time takes advantage of Intel’s big.LITTLE architecture and when Intel spoke about its Alder Lake processor and hybrid architecture along with the new Arc GPUs the company said:

To enable this high level of coordination that improves real-world performance, Intel has partnered with Microsoft to incorporate this revolutionary capability into the next version of Windows 11.
When Microsoft was interviewed on the subject, Mehmet Iyigun – Partner Development Manager, said:

Throughout the development cycle of Windows 11, my team worked with our colleagues at Intel to update and optimize our next operating system to make the most of the Performance Hybrid architecture and Thread Director in particular.
With Thread Director feedback, the Windows 11 thread scheduler is much smarter in dynamically choosing the most appropriate core based on the workload to get the best power and performance.

Alder Lake will be Intel’s first performance hybrid architecture that includes a Performance-core and an Efficient-core to provide significant performance across all workload types. Intel also detailed the new Efficient-core and its Performance-core x86 CPU units that will power the Alder Lake.
  • The Efficient-core microarchitecture is designed for throughput efficiency and efficient offloading of background tasks for multitasking. It runs at low voltage and creates headroom to increase frequency and ramp up performance for more demanding workloads. The new Efficient-core will deliver same performance when compared to Skylake core but with 40% less power.
  • The Performance-core microarchitecture is designed for speed, the highest performing CPU core Intel has built. It pushes the limits of low latency and single-threaded application performance and provides a significant boost at high-power efficiency that can better support large applications. Intel claims that this new Performance-core will deliver 19% better performance over 11th gen cores.
To make both the cores work seamlessly with the OS, Intel developed Intel Thread Director that will enable the OS to place the right thread on the right core at the right time. Also, Alder Lake will power devices ranging from ultra-portable laptops to enthusiast and commercial desktops.

Early benchmarks have shown Windows 11 would be up to 15% faster on Alder Lake than Windows 10.

Leaked Alder Lake-S benchmark suggests it will not live up to Intel’s performance promises​

Intel has been struggling to deliver impressive generational performance improvements over the last few years, and it looks like their new Alder Lake generation will be no exception.

At their recent Architecture Day 2021 event Intel promised that their Alder Lake-S processor would deliver 19% instructions per cycle (IPC) improvements over their Rocket Lake S- processor over a wide range of benchmarks.

A leaked Adobe After Effects benchmark of an Intel Core i9-12900K processor was discovered on Puget Systems’ PugetBench database by Twitter leaker Benchleaks and the improvements are much less impressive.

The results, which range between 1541 and 1575, was on an ASUS ROG STRIX Z690 motherboard, paired with a GeForce RTX 3090.

This can be compared to a recent 8C/16T Rocket Lake-S Core i9-11900K benchmark running on a similar system with DDR4-2133 dual-channel 64GB system compared to the 12900K’s DDR5-4800 dual-channel 64GB.

In the best case, the Core i9-12900K is only around 11.5% faster than the older processor.

Of course, a 10% increase in performance is nothing to sneer at, and battery life improvements related to the big.LITTLE architecture, combined with Windows 11 optimizations, should still make the upgrade more than meaningful.

However, it is also clear that there is no need for those with year-old systems to feel they need to upgrade for a performance boost.

Intel Alder Lake-S, i9-12900K and more, apparently launching sooner than previously rumored​

For a while now, there have been plenty of performance leaks for Intel's upcoming 12th gen Alder Lake-S flagship SKU dubbed Core i9-12900K. These include Cinebench R23 benchmarks, some gaming performance, and more. Aside from leaks, an official review has also been published by SiSoftware where the 16 core/24 thread Core i9-12900K has been compared against previous-gen Intel parts as well as the Ryzen 9 5900X.

All of this confirms that the Alder Lake-S processors are primed for public release sooner rather than later. While we already had a rumored launch date of November 19, it seems the Rocket Lake-S successor could be arriving even sooner according to a fresh report from VideoCardz.

Apparently, Intel Alder Lake-S would be launching on November 4th and it's possible that accompanying Z690 motherboards would also be immediately available. The site claims it has verified this information from its own sources after MSI posted about its free upgrade kit program for the LGA1700 socket on which the upcoming Intel Alder Lake-S platform is based.

Intel's upcoming Core i9-12900K processor is the star of yet another leaked benchmark run, and like several that have come before this one, it adds to the pre-launch hype and expectations surrounding Alder Lake. Obviously we can't put too much stock into pre-release (read: unofficial) benchmarks. But they are out there all the same, and they are collectively setting an interesting bar for Intel to achieve.
