By now, we suspect most of our loyal readers are nicely conscious of what Intel’s Panther Lake is all about. We’ve been discussing it and posting varied leaks and different information about Panther Lake – now formally branded the Core Extremely 300 collection – for practically two years, and right now we lastly get to disclose the way it performs.

Again in October ’25, we attended Intel’s Tech Tour and had been in a position to disclose particulars of the CPU structure and its varied mannequin configurations. Additionally, below the backdrop of CES a few weeks in the past, Intel formally launched its Core Extremely 300 collection processors primarily based on Panther Lake. We dropped a few sneak peeks through the present, however right now we’ve bought a full suite of benchmarks and different particulars on faucet, courtesy of a pre-release Lenovo IdeaPad Professional 5 pocket book, packing the 16-core / 12-Xe Core Extremely X9 388H SoC.

Extra on the system in only a bit – first let’s rapidly recap a few of Panther Lake’s particulars, and tune in to our interview with Intel’s Tom “TAP” Petersen from CES a few weeks again…

Intel Core Extremely 300 Panther Lake Refresher

As we’ve talked about just a few occasions earlier than, Panther Lake is an evolution of Lunar Lake that leverages Intel’s superior 18A course of expertise for its compute tile, with extra versatile reminiscence configurations designed to scale efficiency and effectivity throughout the entire platform’s processing engines (CPU, NPU, IPU, GPU).

Just like the previous-gen Lunar Lake (Core Extremely 200) and older Meteor Lake (Core Extremely 100) SoCs, Panther Lake Core Extremely 300 chips characteristic a disaggregated design, composed of a number of tiles, which can be manufactured on totally different processes, linked collectively through a base die on a single package deal utilizing Intel’s superior Foveros-S 2.5D packaging expertise.

The compute tile, which is dwelling to the CPU cores and media engine, is constructed on Intel’s superior 18A course of, the GPU tile is constructed on Intel 3 or by TSMC relying on the actual configuration, and the platform controller tile can also be manufactured at TSMC.

Though the first marketplace for the Core Extremely 300 collection will likely be next-generation AI laptops, it’ll seem in a wide range of designs and kind components, at a myriad of worth factors, from robots and level of sale techniques, to pc imaginative and prescient techniques and clever edge IoT gadgets.

Initially there will likely be three fundamental Core Extremely 300 collection chip configurations, an 8 CPU core variant (4P, 4LPE) with a 4-core GPU tile, a 16 CPU core variant (4P, 8E, 4LPE) with the identical 4-core GPU tile, and a top-end 16 CPU core mannequin (additionally 4P, 8E, 4LPE) with a a lot larger performing 12-core GPU tile – that’s the model we’ve examined right here.

The platform controller tile on all three configuration is generally related, and presents as much as 20 PCIe lanes (8x Gen 4, 12x Gen 5), 4x Thunderbolt 4 posts, 10x USB ports – break up between USB 2 (8x) and USB 3.2 (2x), Wi-Fi 7, and Bluetooth Core 6.0. The one actual distinction between the platform controller tiles is that every one 20 lanes can be found on the mid-level 16-core Panther Lake configuration, whereas solely 12 lanes can be found on the entry-level 8-core and high 16-core / 12-Xe3 fashions.

The three fundamental Core Extremely 300 collection chip configurations additionally differ by way of their reminiscence help. The 8-core mannequin can make the most of both DDR5 or LPDDR5X reminiscence, at speeds as much as 6,400MT/s or 6,800MT’s, respectively. The mid-level 16 core mannequin will use DDR5 or LPDDR5X reminiscence, however at speeds as much as 7,200MT/s or 8,533MT/s. And the top-end 16-core / 12-Xe3 mannequin will use 9,600MT/s LPDDR5X reminiscence solely. Intel truly has a strict requirement in place to pair the 16-core / 12-Xe3 variant with solely 9,600MT/s reminiscence, to make sure most efficiency and consistency throughout laptop computer fashions, although that reminiscence could be soldered down on the PCB or use LPCAMM modules. We also needs to observe that the utmost reminiscence capability for the 8 and 16-core fashions is 128GB, however the 16-core / 12-Xe3 tops out at 96GB.

For a a lot deeper dive into the Panther Lake structure and particulars about Intel’s superior 18A manufacturing course of, we advise studying our protection from Intel Tech Tour 2025. Suffice it to say, Intel got down to enhance efficiency and effectivity of the entire platform’s processing engines. The CPU cores have been up to date and tuned for 18A, the NPU has been re-balanced for higher utilization, efficiency, and effectivity, and Intel’s Battlemage iGPU is Intel’s strongest and superior but. The highest-tier 16-core CPU / 12-Xe mannequin ought to supply a major leap in efficiency, significantly because it pertains to graphics and AI, relative to equally power-constrained cellular platforms.

As talked about, we bought to check the 16-core CPU / 12-Xe Core Extremely X9 388H processor utilizing a Lenovo IdeaPad Professional 5 laptop computer. The total specs of the system we examined had been as follows.

Lenovo IdeaPad Professional 5 With Core Extremely 3000 Specs

A Fast Tour Of The Lenovo Ideapad Professional 5

The Core Extremely 300-series primarily based Lenovo IdeaPad Professional 5 is a full-featured, premium 16” machine with all of the trimmings. We should level out, nonetheless, that the system we examined is just not a retail-ready mannequin and must be thought-about pre-production. With that in thoughts, some specs, options, or efficiency could change when the techniques begin delivery and hit retailer cabinets. That mentioned, the system arrived in retail packaging, behaved completely all through testing, and appeared prepared for prime time.

We’re not going to dwell an excessive amount of on the system itself however wished to indicate you what we examined. The Core Extremely 300-series primarily based Lenovo IdeaPad Professional 5 is a 16” pocket book, with a ravishing OLED 2.8K panel, 32GB of RAM, 1TB of quick storage, with the entire options enabled by Intel’s platform intact – Thunderbolt (with Thunderbolt Join help), Wi-Fi 7, Bluetooth are all accounted for.

The system’s design doesn’t stray from the present IdeaPad Professional 5 fashions. The machine is packing a 16” OLED show, with a good-sized keyboard (with numpad) and touchpad, first rate audio, and a beefy battery. Lenovo’s web site for the previous-gen IdeaPad 5 lists an 84Wh battery within the specs, however the system we examined experiences the battery measurement at 99Wh, so we assume Lenovo’s upgrading the battery with the Panther Lake era.

The show is a 16″ 2.8k (2880 x 1800) OLED, with contact, and a 30-120Hz variable refresh charge.
