Microsoft Surface Laptop 8 Just Leaked on Geekbench – And the Intel Arc B390 Could Be a Game Changer

Microsoft is expected to deliver new 'for Business' laptops in 13.8-inch and 15-inch sizes, older models pictured.

Microsoft fans, it’s time to get excited (again). After weeks of mixed signals, swirling rumors, and whispers about unexpected delays, the first official-looking benchmark of the upcoming Surface Laptop 8 has finally surfaced online. And the numbers suggest this might not be the iterative update we were all expecting.

Let’s rewind a little. Just a few weeks ago, the consensus among insiders was that Microsoft had quietly pushed back its next-gen Surface PC launch schedule by about a month. No one knew exactly why – supply chain optimization, software polish, or perhaps waiting for Intel to deliver the goods. But if the latest Geekbench leak is anything to go by, the wait might be well worth it.

The first entry for what appears to be a Surface Laptop 8 (13.8-inch, for Business) has popped up on Geekbench’s browser, and it reveals a major shift in Microsoft’s processor strategy.

Intel’s Panther Lake Takes the Wheel

Earlier speculation suggested Microsoft would strictly limit the new Surface Laptop to the lower-end “Core Ultra” variants of Intel’s upcoming Panther Lake family. The rumored ceiling was the Core Ultra 7 366H – a capable 16-core chip, sure, but one that comes with a relatively modest 4‑core integrated GPU. For context, that iGPU barely edges out the Adreno X1‑85 found inside the current Surface Laptop 7 (which, by the way, is still a fantastic machine – you can find renewed units on Amazon here for a solid discount if you don’t want to wait).

But the new leak changes the narrative entirely.

Multiple Geekbench entries now confirm that Microsoft is preparing Intel-powered versions of the Surface Laptop 8 with a much beefier processor: the Core Ultra X7 368H. While this is also a 16-core CPU (likely with a mix of Performance and Efficiency cores), the real story lies in the graphics department.

Instead of the 4‑core iGPU, the Core Ultra X7 368H packs a 12‑core integrated GPU that Intel is supposedly branding as the Arc B390.

Massive GPU Performance Uplift Confirmed

So what does that mean for real-world users? In short, a lot.

Based on our internal benchmark analysis (cross-referencing the leaked OpenCL and Vulkan scores), the Arc B390 inside the Surface Laptop 8 should deliver a massive GPU performance uplift compared to both:

  • Previous Intel-based Surface Laptops (which struggled with anything beyond light photo editing), and
  • The Snapdragon X Elite-backed Surface Laptop 7 (which improved battery life but still had x86 emulation quirks for some creative apps).

If these numbers hold up, the Surface Laptop 8 could finally be a credible option for light 1080p gaming, video rendering on the go, and AI-accelerated workloads without needing a bulky discrete GPU. Microsoft seems to be taking the “laptop that works for everyone” mantra seriously this time.

‘For Business’ Branding and OLED Display Options

The Geekbench listing also clears up a few lingering questions about the device’s identity. The software string explicitly mentions “Microsoft Corporation Surface Laptop for Business 13.8in 8th Ed” – confirming that Microsoft will retain its ‘for Business’ branding for at least one track of the Surface Laptop 8 lineup.

That likely means we’ll see both consumer and commercial SKUs, with the Business models offering features like Windows 11 Pro, advanced security, and maybe even easier repairability (a growing trend in the Surface division).

And for display enthusiasts, there’s more good news. Multiple reports, including those from WinFuture and Roland Quandt, indicate that the next Surface Laptop will finally be available with optional OLED panels. The 13.8-inch form factor is here to stay, but expect deeper blacks, better contrast, and more vibrant colors if you opt for the premium screen upgrade. This would directly compete with the likes of the Dell XPS 13 Plus and MacBook Air’s excellent LCD – but with OLED’s undeniable pop.

What This Means for the Launch Timeline

Given that engineering samples are now live on Geekbench, it’s safe to assume that Microsoft has ironed out whatever caused that rumored “one month delay.” The fact that Intel’s Core Ultra X7 368H is appearing in official-looking tests suggests final drivers are being tuned and production units aren’t far behind.

We’d expect an official announcement from Microsoft sometime in late May or early June 2026, with availability shortly after. A fall back-to-school launch isn’t out of the question, but Microsoft will want to beat the holiday rush.

The Bottom Line

If you’re a creative professional, a business user who dabbles in video calls and light editing, or just someone who wants a premium Windows laptop without compromise, the Surface Laptop 8 (Intel edition) is shaping up to be a must-watch device.

The move from a 4‑core to a 12‑core iGPU is exactly the kind of leap that makes people upgrade. And with optional OLED and that sleek 13.8-inch chassis, Microsoft looks ready to reclaim the “best Windows laptop” crown.
