Architecture Overview
This SKU mirrors the standard Tiger Lake architecture but integrates an Image Processing Unit (IPU) 6.0. The IPU is a dedicated hardware block designed to handle image signal processing for built-in webcams, offloading this work from the CPU and GPU.
CPU Design
The 4 Willow Cove cores and 8 threads feature 1.25 MB of L2 cache per core and an 8 MB shared L3 cache. This ensures low latency and high throughput for typical laptop workloads.
Memory Subsystem
The memory controller supports DDR4-3200 and LPDDR4X-4267, providing high bandwidth which is crucial for maximizing the performance of the integrated Iris Xe graphics.
PCIe & I/O
Includes 4 lanes of PCIe 4.0, primarily intended for connecting high-speed NVMe SSDs directly to the CPU.
Overclocking
The multiplier is locked, but Intel Dynamic Tuning Technology allows dynamic adjustment of power limits based on thermal headroom.
- Dedicated IPU 6.0 for enhanced camera quality
- Massive graphics upgrade (UHD to Iris Xe 80EU)
- Significantly higher boost clocks
Key Highlights
- IPU 6.0 saves CPU cycles during video calls
- Excellent single-core performance
- Iris Xe 80EU graphics
- Great power efficiency
- Supports fast LPDDR4X-4267 memory
- Only beneficial if the laptop uses a MIPI camera interface
- Limited to 4 cores
- Soldered onto the motherboard
- Replaced quickly by 12th Gen mobile chips
History
The release of the IPU-equipped Core i5-1135G7 highlights Intel's strategic pivot towards AI and specialized hardware acceleration. As remote work surged in 2020, demand for high-quality laptop webcams skyrocketed. By integrating IPU 6.
0, Intel enabled OEMs to design thinner laptops with high-resolution MIPI cameras. This allowed features like face authentication and background segmentation to run natively on the silicon without draining the battery. This specific SKU was less commonly advertised but found its way into premium business ultrabooks.
It marked a significant step in Intel's 'Evo' platform initiative, setting new standards for laptop camera quality and video conferencing efficiency.
Improvements over Previous Generation
- Dedicated IPU 6.0 for enhanced camera quality
- Massive graphics upgrade (UHD to Iris Xe 80EU)
- Significantly higher boost clocks
