CPU Comparison

Intel Core i5-1145G7 vs Intel Core i5-1145GRE

A side-by-side comparison of specs, performance and value. The Intel Core i5-1145G7 is a standard consumer mobile processor released in late 2020 as part of the 11th Gen Tiger Lake lineup. Built on the 10nm SuperFin process, it features 4 cores and 8 threads based on the Willow Cove microarchitecture. Designed primarily for thin-and-light laptops, it operates at a base frequency of 2.6 GHz and can boost up to 4.4 GHz. The chip features a 28W default TDP, though it is often configured lower by OEMs to fit 15W ultrabook thermal limits. It integrates Iris Xe Graphics G7 with 80 Execution Units, delivering a massive leap in integrated graphical performance compared to previous generations, enabling smooth 1080p gaming and rapid hardware video encoding. With 8MB of L3 cache and support for PCIe 4.0 (though limited to 4 lanes), it offered excellent single-threaded responsiveness for everyday productivity, content consumption, and light creative workloads, though it is now superseded by newer generations.
