The Intel Core i5-1145GRE is an enterprise-grade embedded processor based on the 11th Gen Tiger Lake-U architecture. Identical in raw compute capabilities to the i5-1145G7E, this variant introduces crucial Error Correcting Code (ECC) memory support, making it suitable for critical edge computing, network appliances, and micro-servers where data integrity is non-negotiable. Featuring 4 cores and 8 threads on Intel's 10nm SuperFin process, it operates at a base clock of 1.5 GHz and boosts up to 4.1 GHz. The configurable TDP ranges from 12W to 28W, providing flexibility for various industrial thermal designs. The inclusion of Intel vPro, TXT (Trusted Execution Technology), and ECC memory elevates this chip above standard embedded offerings, allowing it to be deployed in secure, zero-downtime environments. The integrated Iris Xe Graphics G7 with 80 EUs also provides substantial parallel processing capabilities for AI inference and visual workloads at the network edge.
The Intel Core i5-1145GRE distinguishes itself from the standard embedded Tiger Lake lineup by offering Error Correcting Code (ECC) memory support, a necessity for applications requiring absolute data integrity. With 4 Willow Cove cores and 8 threads, it delivers robust single and multi-threaded performance up to 4.1 GHz.
The 28W configurable TDP allows deployment in both active and passive cooling solutions. Enterprise features like Intel vPro and Trusted Execution Technology (TXT) ensure secure remote management and hardware-rooted boot integrity. Combined with Iris Xe graphics and DL Boost, it is tailored for network routers, secure firewalls, and edge AI appliances where reliability is paramount.

Architecture Overview
The i5-1145GRE utilizes the Willow Cove microarchitecture on Intel's 10nm SuperFin process node. Willow Cove improves upon its predecessor by increasing the L2 cache size to 1.25 MB per core and implementing a redesigned cache hierarchy that reduces latency. The 10nm SuperFin process is a breakthrough in Intel's manufacturing, utilizing a new transistor fin design and interconnect stack to achieve higher frequencies and lower power leakage. This processor specifically leverages Tiger Lake's uncore features to enable ECC memory support, a function not present on all Tiger Lake SKUs. The inclusion of Intel's GNA 2.0 allows dedicated low-power neural processing for tasks like wake-word detection and noise cancellation without engaging the main CPU cores. The integrated Iris Xe Graphics G7 with 80 Execution Units provides a massive leap in graphics and compute density, capable of hardware decoding AV1 video and running parallel compute workloads essential for edge AI applications. The architecture also integrates PCIe 4.0, though strictly limited to 4 lanes on this embedded variant.

History
The Core i5-1145GRE launched during a critical transitional period for Intel in late 2020. Following the delayed and limited rollout of the 10nm Ice Lake family, Intel needed a product to prove their advanced node was viable for mass production. Tiger Lake was that product, debuting the 10nm SuperFin process and Willow Cove cores.
While the standard 1145G7 targeted premium consumer ultrabooks, Intel recognized the growing demand for high-performance, low-power compute in the enterprise embedded sector. The 1145GRE was introduced to serve network appliances and edge servers requiring data integrity. It brought consumer-class IPC improvements and advanced media engines to secure firewalls, SD-WAN routers, and edge database nodes.
This launch solidified Intel's strategy to segment their mobile silicon beyond consumer laptops, ensuring long-term availability for industrial designs and providing a true successor to the heavily utilized 8th Gen embedded lineup.
