Intel Alder Lake leak reveals 12-core laptop chip that challenges AMD

Alder Lake is Intel’s strategy for desktop and mobile going forward, but we’ve heard a lot more about the desktop chips than the laptop ones. Now, we’re starting to see more on mobile configurations, including the 12-core Intel Core i7-1270P that’s reportedly inside an upcoming Samsung Galaxy Book revision.

The leak comes via BenchLeaks, who discovered a listing for the unreleased chip in the GeekBench database. This is after GeekBench announced it would block all pre-release benchmarks. This result not only includes a pre-release chip, it includes the generation’s code name and even the processor name.

[GB5 CPU] Unknown CPU
CPU: Intel Core i7-1270P (12C 16T)
Min/Max/Avg: 7846/22882/17204 MHz
Codename: Alder Lake
CPUID: 906A2 (GenuineIntel)
Scores, vs AMD 5800X
Single: 851, -50.8%
Multi: 3624, -66.3%

The result itself doesn’t mean much. It shows the upcoming Core i7-1270P underperforming compared to the Core i7-1165G7 available in the current Galaxy Book by about 40%. That doesn’t line up with previous leaks, which suggest Alder Lake will bring about a 20% bump to the previous generation, even at the low end.

More interesting are the specs. The result shows a 12-core, 16-thread part with a base frequency of 2.5GHz and a maximum frequency of 9MHz. That isn’t a typo, and you didn’t read it wrong. These kinds of pre-release benchmarks could have features disabled or be run for highly specific use cases, so discount the clock speed and take the final scores with a grain of salt.

Twelve cores are more than any laptop you can buy offers, outside of a few purpose-built machines that rock desktop chips. That includes AMD’s own Ryzen 5000 laptop chips, which have up to eight cores.

However, with Alder Lake, you’re not getting a full 12 cores. Like the rest of Alder Lake, the i7-1270P uses a hybrid architecture. Four of the cores are performant (P) cores, while the other eight are efficient (E) cores.

The P-cores are like any you’d find on a standard processor. They’re big, fast, and can handle heavy-duty workloads. The E-cores are built to run simpler tasks, taking some of the pressure off of the P-cores and freeing up resources for demanding applications. Windows 11 is said to leverage this architecture through Thread Director, which gives the operating system visibility into which tasks are most demanding.

Intel is replacing its wattage classifications — such as Tiger Lake H45 — with a single name: Alder Lake-P. These mobile chips can range from 12W to 45W, and you’ll likely find them everywhere from budget notebooks to high-end gaming machines. For Samsung’s part, an earlier leak revealed a 14-core Alder Lake-P chip, suggesting the upcoming Galaxy Book will come with multiple processor options.

Alder Lake chips are coming this year, but we’re not sure right now if the launch is for desktop, mobile, or both. Multiple rumors point to Intel launching the first desktop chips at its Intel Innovation event on October 27 with a street date later in November. Hopefully, the mobile chips are on the same release track.

Intel may have accidentally leaked the release date for Windows 12

Did we just get a confirmation about the release time frame for Windows 12 -- and from Intel, of all sources? It seems that way. Intel spoke about its predictions for 2024, indicating that it expects 2024 to be a good year for client processors. That's huge for Intel because the next generation of its top processors, Meteor Lake, is set to come out in 2024. However, if Intel is right, it might be a big year for Microsoft, too.

The information comes from a transcript of the Citi 2023 Global Technology Conference. Most of it wasn't too exciting -- fireside chats aren't often that interesting to the masses -- but there's a little comment in there that piqued our interest.

Intel’s Raptor Lake refresh prices have leaked, and hikes are on the way

We're most likely just a couple of weeks away from the release date for the Intel Raptor Lake refresh, and while Intel itself hasn't said much about it, interesting tidbits of information leak out pretty frequently. Today, we got a good look at what might be the pricing of almost the entire lineup. And it looks like price increases are coming, however minor they may be.

We expected that a price hike was likely for the Raptor Lake refresh, and that's exactly what seems to be happening. As per a tip sent to VideoCardz, the majority of the 14th-Gen lineup appeared briefly at a Canadian retailer known as Canada Computers. While the CPUs weren't listed, they could be found by searching for the product names, and that gives an idea of what to expect. Keep in mind that these prices are in Canadian dollars.

The leaks were wrong — Intel Meteor Lake is coming to desktop
Intel CEO talking about Meteor Lake

For months, industry leaks have seemed to confirm that Intel’s Meteor Lake processors won’t be coming to desktop computers. Now, though, Intel has turned that narrative on its head, with the latest info confirming they’ll be launched on PCs after all.

The new information comes from a PCWorld interview with Michelle Johnston Holthaus, Intel’s executive vice president and general manager of the Client Computing Group. PCWorld spoke to Johnston Holthaus at the Intel Innovation 2023 event and managed to wring some previously unknown tidbits out of the VP.
