Intel Panther Lake iGPU Shows Major Performance Gain in Leaked Benchmarks
New Geekbench benchmark results reveal the first performance numbers of the integrated Arc Celestial GPU in the Intel Panther Lake processor. Based on scores from a Core Ultra X7 358H CPU found inside an Asus ROG Zephyrus G14 laptop, the obvious generational difference of power in graphics delivery comes against the backdrop of Intel's earlier claims.
Geekbench OpenCL Benchmark Results
With several valid listings, the Core Ultra X7 358H had varying scores in the Geekbench 6.5 OpenCL test. It has been identified as belonging to the Asus ROG Zephyrus G14 model G405AA with 32 GB of RAM.
- Highest Score Recorded: 52,946
- Lowest Score Recorded: 46,171
This score variation probably reflects that these tests had been done under different system power modes. The listed Arc Xe3 iGPU was under 2500MHz clock speed.
Performance Comparison to Other iGPUs
Compared with existing integrated graphics solutions, the Panther Lake iGPU is one of the most phenomenal performant ones.
- vs. Lunar Lake (Arc 140V): Even taking the lowest score of 46,171, the Panther Lake iGPU almost 49% faster than the best score of the Arc 140V current. This performance gap, however, scales to more than 70% when maximum scores of both chips' performance come into question.
- vs. AMD (Radeon 890M): When comparing the lowest score of Core Ultra X7 358H with the highest score of Radeon, Panther Lake iGPU is about 7% faster than the AMD Radeon 890M. At its peak, the Panther Lake chip is about 23% faster.
What This Means for Laptop Performance
These initial results strongly indicate that Intel's Arc Celestial iGPUs in the Panther Lake series will be a huge leap from the current generation of integrated graphics that are low-powered. The results so far seem to back the Intel claim of a 50% lift in graphics performance relative to its own Lunar Lake architecture.
The Core Ultra X7 358H, the one leaked CPU, is said to have 16 CPU cores (4 in P states, 8 in E states, and 4 are possibly crippled) and 12 Xe3 GPU cores. While OpenCL presents just one point of view, these early benchmarks have pointed to quite a competitive fate for Intel's integrated graphics in laptops.
Intel Panther Lake processors are expected to start appearing on laptops in the following months.
