Target Audience
Strengths & Weaknesses
Pros
- 9W TDP enables true fanless designs
- Extremely low power consumption extends battery life
- Same hybrid architecture as the 1215U
- Silent operation in well-designed chassis
- Adequate for basic computing tasks
Cons
- 29W PL2 severely limits turbo performance
- Lower iGPU frequency (850 MHz vs 1100 MHz)
- BGA 1781 package limits motherboard compatibility
- Part number not well documented
- No meaningful performance advantage over the 1215U at similar prices
- Rarely found in consumer retail channels
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 niche ultra-low-power variant of the i3-1215U that trades performance for extreme efficiency. Its 9W TDP and 29W PL2 make it suitable for fanless designs, but sustained performance is significantly limited.
Best for: Only if you specifically need a fanless or ultra-quiet laptop for basic tasks and find one at a significant discount compared to a 1215U-based model.
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.
