Intel Panther Lake Core Ultra Series 3: Early Benchmarks Reveal Impressive Gains
At CES 2026, Intel introduced its highly anticipated Panther Lake Core Ultra Series 3 mobile processors, headlined by the flagship Core Ultra X9 388H. Intel claims this new CPU delivers up to 60% better multi-threaded performance compared to its predecessor, setting high expectations for the next generation of high-performance laptops. While official laptop releases featuring these processors are scheduled for January 27, early benchmark results have surfaced, offering a first look at what users can expect.
Core Ultra X9 388H Benchmark Performance
According to PassMark benchmark data shared by x86 is dead&back on X, the Core Ultra X9 388H achieved a multi-thread score of 37,904 and a single-thread score of 4,451. This represents a notable 10% improvement over the outgoing Core Ultra 9 285H, which scored 34,436 in multi-threaded tests. Compared to the older Core Ultra 9 185H, the new flagship is approximately 29% faster in multi-core performance.
In single-threaded benchmarks, the Core Ultra X9 388H matches the performance of the 285H but outpaces the 185H by around 20%. These results suggest that while multi-core performance has seen significant gains, single-core improvements are more incremental.
Variability in Early Benchmark Results
It's important to note that these figures are based on the average of two benchmarking runs, which showed considerable variation. In one instance, the Core Ultra X9 388H reached an impressive 40,523 points in the multi-thread test. Despite identical hardware configurations—including the test laptop, memory, and CPU clock speeds—such discrepancies may be attributed to environmental factors or software settings. As with all pre-release benchmarks, these results should be interpreted with caution, but they do indicate strong potential for the Panther Lake lineup.
Comparison with AMD Ryzen AI 9 HX Pro 470
For context, the AMD Ryzen AI 9 HX Pro 470 scored 36,591 in PassMark's multi-core tests and 4,216 in single-threaded performance. This positions Intel’s Core Ultra X9 388H slightly ahead in both categories, reinforcing its status as a competitive option for high-end mobile computing.
Integrated Graphics and Future Outlook
The integrated GPU (iGPU) in the Core Ultra X9 388H has also demonstrated significant improvements. In previous Cyberpunk 2077 benchmarks, it nearly doubled the performance of AMD’s Strix Halo Radeon 890M iGPU, highlighting advancements in graphics capabilities alongside CPU performance.
While these early results are promising for the flagship model, the mid-range Panther Lake CPUs have shown more modest gains in preliminary benchmarks from late 2025. As the official launch approaches, more comprehensive testing will provide a clearer picture of the entire Panther Lake lineup’s capabilities.
