CPU Comparison
Intel Core i5-1145GRE vs Intel Core i5-1155G7
A side-by-side comparison of specs, performance and value. 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 Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
High IPC and 4.1GHz boost ensure quick execution of network routing and control logic.
Excellent single-thread speed makes office apps and browsing feel instant.
Gaming
Not intended for gaming; integrated graphics handle UI and media playback only.
Iris Xe 80EU performs well in older titles and esports at 1080p Low settings.
Virtualization
Strong hardware virtualization support (VT-x, VT-d, EPT) makes it capable of running SD-WAN or light VMs.
Can run a light VM, but 4 cores limit parallel virtualization.
Efficiency
Excellent performance-per-watt, especially when scaled down to the 12W cTDP limit.
Good power efficiency, though surpassed by newer 10nm and TSMC nodes.
