About the Intel Core i5-1145G7 CPU
The Intel Core i5-1145G7 is a 4-core (8-thread) processor built for the mobile CPU market. It launched in Q3 2020. It is part of Intel's Core i5 lineup, which is based on the Willow Cove-U microarchitecture. The i5-1145G7 is compatible with Intel BGA 1449 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe Graphics G7 80EU integrated graphics solution.
Memory and Cache
The Core i5-1145G7 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-1145G7 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.
Cores and Clock Speeds
The Core i5-1145G7 features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.6 GHz, and it can boost up to 4.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The Core i5-1145G7 includes an integrated graphics solution called Iris Xe Graphics G7 80EU. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.
