Microsoft is doubling down on x86 architecture for its next generation of 2-in-1 devices, resisting the industry-wide pivot to ARM. Early Geekbench 6 benchmarks for the upcoming Microsoft Surface Pro 12 have leaked, revealing Intel's new Panther Lake processors under the hood. This hardware choice indicates that the company is prioritizing legacy enterprise compatibility over the mobile-first trends dominating the current market.
While competitors like Apple and devices powered by the Qualcomm Snapdragon X Elite dominate the mobile ARM space, Microsoft is charting its own course. By equipping the Microsoft Surface Pro 12 with the Core Ultra 5 335 processor, the company aims to boost the integrated graphics capabilities of its hybrid platform while maintaining the robust software support that professional users demand.
Intel Panther Lake Performance and Geekbench 6 Scores
The leaked Geekbench 6 listings provide a clear look at the CPU's raw processing power. The device achieved a single-core score of 2484 and a multi-core score of 10172. When compared to baseline data from hardware analysis platforms like Nanoreview, the Core Ultra 5 335 typically hits 2631 in single-core and 10501 in multi-core tests.
| Specification | Detail |
|---|---|
| Processor | Intel Core Ultra 5 335 |
| Core Count | 8 Cores (4 P-Cores, 4 LPE-Cores) |
| Single-Core Score | 2484 |
| Multi-Core Score | 10172 |
| Base TDP | 25W (12W Min, 55W Max Turbo) |
This data translates to nearly identical multi-core performance compared to reference boards, but it registers a slight 6% drop in single-core output within Microsoft's specific form factor. The processor features an eight-core architecture, split evenly between four performance-focused P-Cores clocking up to 4.6 GHz, and four energy-efficient LPE-Cores operating at up to 3.4 GHz.
Hardware Variants and Native 5G Connectivity
Graphics processing is handled by Intel's Arc architecture, utilizing four Xe3 cores, which represents exactly one-third of the graphical capacity found in top-tier Panther Lake models. Furthermore, the leaked data confirms the existence of two distinct hardware variants currently in testing.
The model carrying the technical reference 900_MAA is powered by the Core Ultra 5 335, while a secondary variant labeled 3467_PUE utilizes the Core Ultra 5 325 - a slightly scaled-back processor operating with a 100 MHz speed reduction. To support heavy mobile productivity, the base configuration starts at 16 GB of RAM, with technical trials confirming the existence of high-end units equipped with 24 GB and 32 GB of memory. The inclusion of native 5G connectivity ensures constant internet access for professionals working outside standard Wi-Fi zones.
Thermal Throttling in a Thin Chassis
The 6% dip in single-core performance compared to standard Intel Panther Lake benchmarks is a telling detail. It strongly suggests that Microsoft is aggressively managing thermal output to prevent overheating within the notoriously thin chassis of the Microsoft Surface Pro 12. Rather than pushing the chip to its absolute limits, the engineering team appears to be capping peak frequencies to maintain battery life and system stability.
This strategic throttling, combined with the introduction of 24 GB and 32 GB RAM tiers, highlights exactly who this device is for. Microsoft is not trying to win a raw benchmark war against Apple's M-series chips. Instead, they are building a highly reliable, 5G-connected workstation for enterprise power users who require flawless x86 virtualization, heavy multitasking capabilities, and uninterrupted connectivity in the field.
