Samsung and ASUS Geekbench scores reveal Intel’s Panther Lake CPUs | Early benchmarks hint at a generational leap in laptop performance

by

We’ve recently seen Intel’s Core Ultra 300 Panther Lake chips in action thanks to new listings on Geekbench. VideoCardz spotted the results, which come from actual laptops. One test focuses on AI performance using the ONNX CPU backend, while the other measures GPU computing power with OpenCL.

I’m really excited about two laptops that are coming out soon! One is the new Samsung Galaxy Book6 Pro – it seems like an updated version of the Galaxy Book5 Pro I’ve been reading about, and it’s got an Intel Core Ultra 5 338H processor. The other is a refreshed ASUS ROG Zephyrus G14, which also features a powerful Intel Core Ultra X7 358H processor. Both sound amazing!

These listings are the first solid evidence of Intel’s plans for its upcoming Core Ultra Series 3 processors, codenamed Panther Lake. They confirm the processor names, how many cores each model will have, and the capabilities of the integrated graphics (Xe3).

Let’s quickly cover how Intel’s different types of cores work. ‘P-cores’ handle demanding tasks, ‘E-cores’ take care of simpler or background processes, and ‘LP-cores’ are designed to maximize battery life when you’re doing everyday things like browsing or checking email.

Samsung Galaxy Book6 Pro leak confirms the Core Ultra 5 338H

The Intel Core Ultra 5 338H is a processor that uses 28 watts of power and has a total of 12 cores. These cores are divided into three types: 4 performance cores, 4 efficient cores, and 4 low-power cores. A recent benchmark test (Geekbench) shows the processor working with two groups of cores: one with 4 cores and another with 8. The base clock speed is 1.90 GHz.

The AI performance was measured using the ONNX framework with CPU processing, not the dedicated AI processor (NPU). In Geekbench AI 1.4, the scores were 4,136 for standard precision, 1,764 for reduced precision, and 7,612 for optimized, smaller models.

The system had 32 GB of RAM and was using Windows 11 Pro. These initial tests show how the processor handles AI tasks on the upcoming Panther Lake system, but they don’t include results from the dedicated AI processor (NPU) or graphics card (GPU). Because AI performance can vary a lot between devices, these results are more of a first impression than a definitive performance evaluation.

ASUS ROG Zephyrus G14 leak reveals the higher-end Core Ultra X7 358H

The Core Ultra X7 358H is a powerful processor with 16 cores – 4 performance cores, 8 efficiency cores, and 4 low-power cores – and consumes up to 28 watts. It can reach a maximum boost speed of 4.7 GHz, with a base speed of 1.90 GHz. Its integrated graphics, the Xe3 iGPU, has 12 cores, translating to 96 compute units. During testing, the iGPU was able to use up to 16 GB of the computer’s RAM, which is typical for integrated graphics solutions.

We’ve previously written about Intel’s ongoing ARC graphics and how it’ll change with Panther Lake.

We only have performance data from a graphics test (OpenCL), not the main processor. The OpenCL scores weren’t consistent, ranging from 46,171 to 52,014 in different tests. These scores give a rough estimate of how well the new Xe3 graphics chip performs in Geekbench’s graphics test.

VideoCardz compared the test results to other similar graphics cards. In this particular test using OpenCL, the integrated graphics on the X7 358H performed nearly as well as the RTX 3050 Laptop GPU. It also outperformed the Intel Arc A550M and the Arc 140T integrated graphics planned for future Arrow Lake processors. It’s important to note that these comparisons are based solely on the scores from the Geekbench benchmark.

FAQ

What is Intel Panther Lake?

Panther Lake is the next generation of Intel’s mobile processors, part of the Core Ultra 300 lineup. It’s built using Intel’s advanced 18A process and includes powerful Xe3 Arc Celestial integrated graphics.

Which laptops were tested?

Recent benchmark test results revealed performance details for upcoming laptops from Samsung (the Galaxy Book6 Pro) and ASUS (the ROG Zephyrus G14). Both laptops were tested with Intel’s new, unreleased Panther Lake processors.

What kind of performance gains are we seeing?

The integrated graphics in the Panther Lake processor are significantly faster – up to 70% better – than Intel’s older Arc 140V graphics. In certain tests, it even outperforms the AMD Radeon 890M.

When is Intel’s Panther Lake lineup expected to release?

Intel hasn’t said exactly when its new processors will be available. However, Intel typically showcases its latest technology at the Consumer Electronics Show (CES) in January, and we anticipate seeing laptops featuring the new “Panther Lake” processors unveiled there, with those laptops expected to hit stores in spring 2026.

Do these benchmarks reflect final performance?

Geekbench scores you see online aren’t always final. These tests are often run on early versions of devices with unfinished software and settings, meaning the actual performance of the final, released product could be different.

What core layout does Panther Lake use?

As a tech enthusiast, I’ve been following the latest Intel leaks, and it’s really interesting to see how they’re building these new processors. Both chips use Intel’s hybrid architecture – combining Performance-cores (P-cores), Efficient-cores (E-cores), and Low-Power cores (LP-cores) for a balance of power and efficiency. The Core Ultra 5 338H has 4 P-cores, 4 E-cores, and 4 LP-cores, while the more powerful Core Ultra 7 358H steps things up with 4 P-cores, 8 E-cores, and 4 LP-cores. It’s cool to see how they’re tweaking the core counts to hit different performance levels.
