Intel’s most powerful CPUs may not launch until 2024

Intel’s next two generations of desktop CPUs are both exciting and confusing. Luckily, new information has come to light around what to expect.

The report comes from German publication Igor’s Lab, which claims to have seen Intel’s internal performance projections for these next two generations of chips. The report also affirms some of the details in Intel’s desktop road map, including that the 14th-gen fall release will be a Raptor Lake Refresh rather than true Meteor Lake desktop chips. It also says the 15th-gen Arrow Lake is anticipated to launch in 2024.

To ensure a fair comparison, Intel has used the current-gen Core i9-13900K for normalization with corresponding models of Raptor Lake Refresh and Arrow Lake. It is important to note that these numbers are just an estimate and will potentially differ from the final performance numbers of the upcoming CPUs.

All three processors share the same configuration, with eight performance cores and 16 efficiency cores. The numbers also suggest that Arrow Lake will consume almost the same power as Raptor Lake. The PL1 and PL2 for Raptor Lake and Raptor Lake refresh is set to 253 watts, while Arrow Lake is set to 250W.

The first graph suggests that Raptor Lake Refresh will offer a performance increase between 1% to 3%, which will be primarily due to increased clock speeds that are expected to go as high as 6GHz. Arrow Lake, on the other hand, delivers a 7% to 20% performance increase, where the highest improvements are set to be in multi-core operations.

The next slide focuses on the SPEC CPU benchmark package that contains standardized, CPU-intensive suites for measuring and comparing compute-intensive performances. This ensures a comparative measurement of compute-intensive performance across broad a spectrum of hardware using workloads derived from real user applications. Here, Raptor Lake Refresh experences a gain of 1% to 4%, depending on the application. Arrow Lake gains performance ranging from 3% to 21%, which is a significant jump, specifically in the floating-point runs.

The last graph gives us information about the integrated graphics. Raptor Lake Refresh uses the same HD 700 series GPU as the Core i9-13900K, with 32 EUs and clock speeds of up to 1.65GHz. Since both are using the same configuration, the performance is also similar. However, Arrow Lake will be using the new Xe LP graphics, and will also be the first desktop CPU where the integrated GPU is mounted using Foveros packaging that stacks chipsets vertically. While there is no confirmation around the number of EUs or the clock speeds, the slide suggests an impressive increase of 220% to 240% compared to the 100% of Raptor Lake.

Arrow Lake is also expected to arrive with a new socket that is rumored to be LGA1851. While the dimensions of the socket are expected to be similar to the LGA1700, it will have 9% more pins. Thus, Intel should introduce motherboards with 800-series chipsets. As for cooler manufacturers, they might need to introduce new mounting hardware once again. Of course, none of this information is final and could change at the last minute.

Why the most powerful laptops of 2024 might not use Intel’s latest chips

Intel's about to add a whole lot of new chips to its list of top processors, and we just got a peek at a few of them out in the wild ahead of time. According to a new leak, upcoming Dell XPS and Alienware laptops will feature some of Intel's latest Meteor Lake CPUs, including the Core Ultra 7 and Core Ultra 9. However, Intel's previous-gen Raptor Lake processors are also making a surprising appearance in the lineup, which isn't a great sign.

Windows Report posted an exclusive leak that shows us a whole range of high-end laptops, which the publication predicts should be announced during CES 2024. This includes ultrathin Dell XPS 13, 14, and 16 laptops, but there are plenty of options for gamers too, including the Alienware m16 R2, x16 R2, and m18 R2. All of these laptops are said to feature Nvidia's best GPUs from the RTX 40-series.

Some surprising details on Intel’s upcoming 14th-gen laptops just leaked

One of the first laptops powered by Intel’s upcoming 14th-gen Meteor Lake CPUs has been spotted online, and based on what we're seeing, the prices look surprisingly affordable.

The information originated on X (formerly Twitter) from @momomo_us, who initially shared details about these new laptops via Newegg US. The post disclosed information about the expected CPUs and key specifications of the laptops. Among MSI's lineup of work laptops featuring Meteor Lake CPUs, the Prestige 13 and 16 are the first ones identified. The leak also mentions the CreatorPro 16 Studio, as well as popular gaming SKUs, the Stealth 14 and 16, although specs for these were not provided.

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.
