Two more Intel Panther Lake processors have popped up in online benchmark listings, giving us an early look at what could power the next wave of thin-and-light laptops and other efficiency-focused PCs. The chips in question are the Intel Core Ultra 5 335 and Core Ultra 5 325, and while the results offer some useful clues about specs, they don’t yet allow a clean performance comparison against earlier Core Ultra parts.
Both Core Ultra 5 335 and 325 show up as 8-core, 8-thread CPUs built around a 4 Performance-core + 4 LP-E (low-power efficiency) core design. Notably, these models appear to skip traditional Efficient cores entirely, positioning them as successors to Core Ultra 200V-series style designs focused on balanced performance and power behavior.
In the benchmark entries, the two processors land very close to each other in both single-core and multi-core results, which tracks with how similar their specifications are. The biggest listed difference is boost frequency: the Core Ultra 5 325 is shown boosting up to 4.5 GHz, while the Core Ultra 5 335 reaches up to 4.6 GHz.
One important detail for anyone trying to judge performance: these results come from Geekbench 5.5 rather than Geekbench 6. Since many recent CPU leaks and comparisons rely on Geekbench 6, mixing the two can be misleading. That’s why these numbers shouldn’t be treated as a direct “faster or slower than last gen” verdict yet. Across multiple result pages, the Core Ultra 5 325 and 335 generally hover around the 2,000-point range for single-core and above 9,000 points for multi-core in Geekbench 5.5.
The listings also reveal a meaningful cache upgrade. Both chips are confirmed with 12 MB of L3 cache, which is reportedly 4 MB higher than some comparable Core Ultra 5 200V parts such as the 228V and 238V. Cache increases can help in a wide range of real-world workloads, from productivity tasks to lighter content creation, though the actual impact will depend heavily on final laptop configurations, power limits, and cooling.
These new Panther Lake CPUs are part of a broader family expected to include HX, H, and standard (non-H/HX/U) models. The regular Panther Lake variants are aimed at power-efficient devices but are still expected to run in a higher 25W to 55W TDP range, compared with the 17W to 37W range commonly associated with Lunar Lake CPUs. In other words, Panther Lake in this class may target a bit more sustained performance headroom, assuming OEM designs let the chips stretch their legs.
A preliminary Panther Lake lineup listing circulating online places the Core Ultra 5 335 and 325 as 25W parts with up to 55W turbo behavior, paired with a 4-core Xe3 integrated GPU configuration (with iGPU clocks not yet detailed). If more Geekbench 6 results appear soon, they should make it easier to compare Panther Lake against existing Core Ultra laptop processors on a more apples-to-apples basis—especially since a previously seen Core Ultra 7 365 entry didn’t impress as much as expected.
For now, the Core Ultra 5 335 and 325 leaks are best viewed as a confirmation of key specs (core layout, boost clocks, and L3 cache) rather than a final word on performance. As more benchmarks show up—and as shipping laptops with finalized power profiles arrive—the real picture of Panther Lake’s efficiency and speed should come into focus.
