The Intel Core i5-1135G7 is an energy-efficient processor for thin and light laptops launched in the third quarter of 2020. This Tiger Lake-UP3 processor features four Willow Cove cores operating at a base frequency of 2.4 GHz at 28W cTDP-up, that can turbo boost up to 4.2 GHz for a single core and up to 3.8 GHz when all the four cores are running. The Core i5-1135G7 supports hyper-threading technology processing up to 8 threads at any given time thus completing tasks faster. The processor cores and the iGPU have access to 8 MB of Intel Smart Cache.
The chip incorporates Intel’s Iris Xe Graphics iGPU which is much faster than the Intel UHD 620 series and is slightly faster than the Intel Iris Plus G7 used commonly Ice Lake processors. The iGPU (Iris Xe Graphics) uses 80 execution units that operates at a maximum turbo boost frequency of 1.3GHz. This Iris Xe graphics can handle up to 4 display outputs simultaneously which includes a maximum resolution of 4096×2304 at 60Hz for both HDMI and integrated flat panel and 7680×4320 at 60Hz for DP interface.
The chip is manufactured on the 10 nm Intel SuperFin process with a low core count to render the Core i5-1135G7 processor relatively power efficient. Its default TDP is set between 12W at 900MHz to 28W making it suitable for thin ultraportable laptops including Notebooks. This CPU is compatible with dual DDR4-3200 or LPDDR4x-4267 memory channels supporting a maximum memory capacity of 64 GB. Also, it supports Thunderbolt 4, PCIe 4.0, MIPI SoundWire alongside other advanced technologies on the chip’s die.
The Boost sustainability depends a lot on the cooling system performance as well as the TDP settings. Intel Core i5-1135G7 will naturally get hot under gaming and high workloads which could lead to thermal throttling issues. It’s important to note the chip does not support overclocking therefore any noticeable performance boost and power efficiency improvements will be seen under balanced workloads. Generally, the Core i5-1135G7 will give users more than enough performance for daily office tasks, light photo or video editing, multi-tasking, etc. Plus, it can also handle many 2019 games in a decent manner.
