AI / ML

Intel Core Ultra 5 338HGood (for local AI)
  • Dedicated NPU 5 with 47 INT8 TOPS accelerates Windows Studio Effects and local AI models.
  • CPU and GPU also support DL Boost and XMX-based AI workloads, but TOPS are lower than on higher-end Ultra 7/9 models.
  • Well suited for consumer AI features and small models, not for training or large-scale inference.
Intel Core Ultra X7 358HVery Strong
  • NPU 5 with 50 TOPS INT8 and strong GPU AI throughput.
  • Intel shows up to ~5.5× better GPU AI vs older Raptor Lake‑P and large leads vs some AMD Strix Point competitors in Geekbench AI and UL Procyon AI workloads.
  • Well suited for local small‑medium LLMs, AI background effects and image generation.

Gaming

Intel Core Ultra 5 338HVery Good (for integrated graphics)
  • Arc B370 10 Xe3 cores at up to 2.4 GHz deliver roughly 70% more performance than Intel’s previous Arc 140V/140T iGPUs and comfortably outpace AMD’s Radeon 890M in synthetic tests.
  • At 35 W, the B370’s Time Spy Graphics score is around 5,933 points, placing it between older RTX 3050 Ti and RTX 4050 laptop GPUs in some scenarios.
  • Best suited for 1080p medium settings; more demanding AAA titles may require resolution scaling or lower presets.
Intel Core Ultra X7 358HGood
  • Arc B390 with 12 Xe3 cores is a major step up from Arc 140V/Xe2 iGPUs.
  • Fine for 1080p medium/high in many esports and AAA titles with upscaling.
  • Still not a match for a dedicated RTX 4050/4060 laptop GPU at higher settings.

Industry Impact

Gaming
Moderate
Moderate – Arc B390 raises the baseline for integrated graphics but doesn’t eliminate the need for discrete GPUs for serious high‑refresh gaming.
Workstations
Low
Moderate – good for light workstation tasks and creators who don’t need ECC or massive PCIe expansion.
Content Creation
Moderate
High – strong CPU multi‑thread plus capable iGPU and NPU make it attractive for video and photo editing on the go.
Virtualization
Low
Moderate – adequate for light VMs and dev environments, but not a replacement for Xeon or desktop‑class HEDT.
