Panther Lake vs Xbox Series S: Test Details
| Specification | Panther Lake (Arc B390) | Xbox Series S |
|---|---|---|
| Processor | Intel Core Ultra X9 388H | Custom AMD RDNA 2 |
| GPU | Arc B390 (12 Xe3 cores) | Custom RDNA 2 |
| Test Device | Lenovo IdeaPad Pro 5 | Xbox Series S console |
| Power Limit | 30W | N/A (console) |
| Resolution | 1440p | 1440p output |
| Upscaling | FSR 2 Balanced | FSR 2 (from 720p internal) |
| FPS (30W cap) | 29.54 fps | ~27.6 fps |
| FPS (uncapped) | 32.77 fps | 26 fps |
| Average Power | 26.8W (peaks 31W) | N/A |
Digital Foundry tested a Lenovo IdeaPad Pro 5 with Core Ultra X9 388H and Arc B390 graphics. At 30W (handheld PC standard), it averaged 29.54 fps—7% faster than Xbox Series S in Alan Wake 2.
Uncapped, Panther Lake reached 32.77 fps. Increasing to 45W yielded minimal gains due to thermal limits.
Comparison Context
Xbox Series S uses lower settings than PC’s “Low,” outputs 1440p via FSR 2 from 720p internal, and applies foliage/shadow cuts.
PS5-equivalent testing showed limits: PS5 averaged 55.25 fps vs Panther Lake’s 28.91 fps—a 92% gap. Alan Wake 2 behaves unpredictably on mobile iGPUs, so this shouldn’t generalize.
Performance Context
Arc B390 beats GTX 1060 and RX 580 but trails RTX 2060 and RX 6600. In ray tracing, Arc B390 sometimes matches RX 6600 via system memory access versus 8GB VRAM limits.
Intel announced Panther Lake handhelds in 2026 with MSI and Acer. The 25-35W envelope suits portable devices.
Arc B390 uses Intel‘s Xe3; Series S runs six-year-old RDNA 2. Visit TechnoSports tech news for updates.
