One more Panther Lake SKU got benchmarked on Geekbench, but this one has only four GPU cores. The iGPU performs on par with entry-level GPUs, and here's how it did against its rivals.
Core Ultra 7 366H Spotted on Geekbench With Specs and iGPU Performance That Trades Blows With GTX 1050 Ti
Slowly, we are seeing more Intel Panther Lake CPUs in action. With the CPU series nearing its launch, several of its early engineering samples have been tested on various platforms. We mostly saw Core Ultra X7 SKUs being benchmarked, which boast 12 Xe3 Cores, but since Panther Lake will also have slower Core Ultra 7 variants, here is one, which offers 4 Xe3 Core-based iGPU.
On Geekbench, its specs have been leaked, and we can see that it is a 16-core CPU, as was reported previously. The core configuration will be 4x Performance + 8x Efficient + 4x LP-E cores. The base clock is 2.00 GHz, which is correct, but unlike what is visible on the Geekbench result page, the CPU can reportedly boost up to 4.8 GHz. The L3 cache is 18 MB, which is also correct according to earlier leaks.
As for the iGPU, it is expected that this SKU will boast 4x GPU cores based on the Xe3 architecture and even though the CPU itself is a competitor to the Ryzen 7 mobile series, the iGPU can't be compared directly to the Radeon 860M. That said, for the sake of comparison, we will include the benchmarks of both the Radeon 860M and the Radeon 840M present on the Ryzen AI 5 340 APU.
Core Ultra 7 366H vs Competitors in Geekbench Vulkan Test
The Ultra 7 366H iGPU scored 22,813 points in the Geekbench Vulkan test, which is slightly higher than the GTX 1050 Ti. Compared to the 4-Core Radeon 840M, it's 26% higher, but when compared to the 8-Core Radeon 860M, it's nearly 40% slower. This is expected since the CPU is aimed at the mainstream laptop segment, and isn't a direct competitor to powerful iGPUs available on Strix Point or Ryzen AI 7 series Krackan Point.
Panther Lake SKUs with 10 or 12 Xe3 GPU cores have already shown nearly RTX 3050-equivalent performance, and much higher cores than Radeon 890M in tests like 3DMark Time Spy. However, those SKUs are going to be much more expensive than the 8 or 12-core Panther Lake variants, which is why, for the budget segment, AMD Krackan Point looks unchallenged at the moment.
