Intel Core Ultra X7 358H: First Look at Panther Lake’s Xe3 GPU Performance
Intel’s upcoming Core Ultra X7 358H processor has surfaced in recent Geekbench benchmarks, offering the first glimpse of the new "Panther Lake" series and its integrated 12-core Xe3 GPU. This marks the debut of the Xe3 graphics architecture in its full integrated form, setting a new standard for Intel’s iGPU capabilities.
Panther Lake Architecture and Specifications
The Core Ultra X7 358H features a sophisticated CPU design, combining four performance cores (P-cores), eight efficient cores (E-cores), and four low-power efficient cores (LPE-cores), for a total of 16 CPU cores. The processor reaches a maximum clock speed of 4,776 MHz. Notably, this model boasts the fastest memory subsystem in the Panther Lake lineup, supporting speeds up to 9,600 MT/s.
While the tested unit is likely an engineering sample, its clock speeds are expected to be close to the final retail version. The integration of the Xe3 GPU with 12 cores represents a significant step forward for Intel’s graphics technology, aiming to deliver improved performance for both gaming and productivity workloads.
Geekbench OpenCL Results: How Does Xe3 Stack Up?
In Geekbench’s OpenCL benchmark, the Panther Lake iGPU achieved a score of 52,014 points. This result places it in the same performance bracket as NVIDIA’s GeForce RTX 3050 desktop GPU, a notable achievement for an integrated graphics solution. However, it’s important to recognize that Intel’s integrated GPUs have historically scored lower in Geekbench’s OpenCL tests compared to AMD and NVIDIA counterparts, due in part to software and driver optimizations.
Comparing generational improvements, the 12-core Xe3 GPU in Panther Lake demonstrates approximately a 25% performance increase over the previous Arrow Lake-H Arc 140T iGPU in the same benchmark. Interestingly, the new iGPU’s performance is also comparable to the discrete Arc A550M GPU, which features 16 cores based on the first-generation Xe "Alchemist" architecture, a 60-80 W TDP, and 8 GB of GDDR6 memory.
Driver Optimization and Future Expectations
The current benchmark results should be interpreted with caution, as pre-release hardware often lacks finalized driver support. Intel is expected to release updated drivers ahead of the official Panther Lake launch, which should unlock the full potential of the Xe3 GPU and further improve performance in real-world applications and benchmarks.
As Intel continues to refine its integrated graphics technology, the Panther Lake series and its Xe3 GPU represent a promising advancement for users seeking robust performance without the need for discrete graphics cards.
