Strengths & Weaknesses
Pros
- Hybrid architecture brings efficiency gains to the i3 tier
- 2 P-cores provide responsive single-threaded performance
- 4 E-cores handle background tasks without waking P-cores
- Broad memory compatibility for OEM flexibility
- 15W TDP enables excellent battery life
- 20 PCIe Gen 4 lanes for fast storage
Cons
- Only 8 threads limit heavy multitasking
- 15W base power constrains sustained performance
- E-cores lack Hyper-Threading
- UHD 64EU integrated graphics are weak for 3D workloads
- BGA package means no CPU upgrade path
- E-core L2 cache is 2MB per module (less than Raptor Lake's 4MB)
Pros
- 8 cores provide good parallel throughput for the price
- Very low power consumption with 9W configurable TDP
- UHD Graphics 770 is better than expected for this tier
- Fully dynamic clock domains for granular power management
- Supports AVX-VNNI instruction extensions
- Enables very affordable mini PCs and Chromebooks
Cons
- No P-cores means weak single-threaded performance
- Single-channel memory halves bandwidth
- Only 9 PCIe 3.0 lanes severely limit expansion
- 6MB L3 cache is small for 8 cores
- Gracemont IPC is significantly lower than Golden Cove
- PCIe 3.0 is a generation behind the 4.0 support on U-series chips

Our Verdict on Each
A competent entry-level hybrid mobile chip that introduced the P+E architecture to the i3 laptop segment. Adequate for everyday tasks, though the 8-thread ceiling and 15W power limit constrain heavier workloads.
Best for: Purchasing a budget to mid-range laptop in 2022-2023 for everyday tasks, schoolwork, and office use where battery life matters more than raw performance.
Read the full reviewA unique all-E-core processor that offers 8 threads of parallel performance at very low power, but the absence of any P-cores means single-threaded performance is significantly behind hybrid chips. Best suited for devices where core count marketing and power efficiency matter more than snappy responsiveness.
Best for: Budget mini PC or Chromebook purchase where 8-core parallelism at low power is valued, and single-threaded performance is not critical.
