CPU Comparison

Intel Core i5-1145G7E vs Intel Core i7-8665UE

A side-by-side comparison of specs, performance and value. The Intel Core i5-1145G7E is a specialized 11th Generation Tiger Lake-U processor tailored for embedded and edge computing applications. Released in late 2020, this quad-core, eight-thread CPU leverages Intel's 10nm SuperFin process and Willow Cove architecture to deliver a balance of performance and power efficiency. Operating at a base frequency of 1.5 GHz with the ability to boost up to 4.1 GHz, it is designed to handle intermittent compute spikes common in industrial environments. The 'E' suffix denotes its extended lifecycle support, ensuring availability for long-term deployments. With a configurable TDP ranging from 12W to 28W, system designers have the flexibility to optimize for either fanless low-power operation or higher sustained performance. It also features Iris Xe Graphics with 80 Execution Units, providing capable graphical and parallel processing power for edge inference, digital signage, and IoT workloads. This makes it a versatile choice for modern embedded systems requiring robust x86 compatibility.
