Intel Alder Lake-S leak reveals specs of its 16-core, 24-thread flagship

An engineering sample of Intel’s upcoming Alder Lake-S processors was obtained by Igor’s Lab, offering a look at clock speeds, core counts, and power draw from Intel’s next-generation chips. The leaked processor is tentatively named the Intel Core-1800, referencing the base clock speed of 1,800MHz the processor is currently able to hit.

It’s an engineering sample, so the base clock speed will go up. The leak shows that the processor can hit a boost clock of 4.6GHz on the first two cores, 4.4GHz on three to four cores, 4.2GHz on five to six cores, and 4.0GHz on seven to eight cores. This processor, which is apparently the most powerful out of the lineup, features 16 cores and 24 threads and a base thermal design power (TDP) of 125 watts.

Only eight of those cores are “big” cores, though. Intel is using a hybrid design with Alder Lake, using new, fast cores — named Golden Cove — for intensive tasks while employing slower Atom-based cores — named Gracemont — for simple or background tasks. The leaked processor comes with eight Golden Cove cores with 16 threads and eight Gracemont cores with eight threads, for a total of 16 cores and 24 threads. According to the leak, the Gracemont cores run at 3.4GHz for the first four cores and 3.0GHz for the subsequent cores.

This hybrid model is popular with mobile-based CPUs from ARM and has shown up in the Apple M1 chip. Intel is the first to bring the “breakthrough CPU architecture” to the desktop market. A leaked slide from Intel claims the new processors offer a 20% increase in instructions per clock and up to a 2x performance uplift in multithreaded workloads. The slide also shows the new range will support DDR5, PCIe 5.0, Thunderbolt 4, and Wi-Fi 6.

To use the new features, you’ll need a Z690 motherboard. The leak confirms that Alder Lake will use the LGA1700 socket, making Alder Lake incompatible with Z490 and Z590 boards that use the LGA1200 socket.

The leak shows a bright future for Intel, which it needs. Intel has long struggled to move away from its 14nm process. The company launched the Rocket Lake product line earlier this year using this process, and it was met with mediocre reviews due to subpar performance and high power draw. Alder Lake features the new 10nm process, which could help catapult Intel to the front of the desktop market.

I upgraded my Framework Laptop’s CPU in under 15 minutes
Upgrading the Framework Laptop with the components on a table.

The Framework Laptop had quite an ambitious premise upon release -- a "modular" laptop that was made to be tinkered with and upgraded. After using the device myself, I walked away convinced that Framework was onto something. At least, in theory.

The true test would come when it was time for a major upgrade, when the clever design and sustainable practices of a fully upgradable laptop could shine. And a year later, I've received the Intel 12th-gen Mainboard upgrade, and I'm more sold on Framework's philosophy than ever before.

Intel Raptor Lake-S specs leak, but one key detail is missing
Intel Raptor Lake chip shown in a rendered image.

New details about Intel's upcoming 13th-generation Raptor Lake-S processors just emerged, giving us even more insight into the specifications and performance of these CPUs. The information was leaked as part of an Intel NAS Workshop presentation that took place in Shenzhen, China.

At first glance, everything looks great, with higher clock speeds and core counts. However, one key detail seems to have been passed over -- there is no mention of PCIe Gen 5.0 support for M.2 modules.

Here’s why AMD really needs to beat Intel to next-gen CPUs
AMD Ryzen 7 5800X3D.

According to a report by Joseph Moore of Morgan Stanley, AMD is expected to see a large drop in revenue this year in its PC segment. Team Red's revenue is expected to decline by 26% in 2022.

This highlights just how important it is for AMD to get its next-generation Ryzen 7000 processors out there soon, and even more so, how crucial it is for Zen 4 to arrive before Intel Raptor Lake.
