About the Intel Core i7-8650U CPU

The Intel Core i7-8650U is a 4-core (8-thread) processor built for the mobile CPU market. It launched in Q3 2017. It is part of Intel's Core i7 lineup, which is based on the Kaby Lake-U Refresh microarchitecture. The i7-8650U is compatible with Intel BGA 1356 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD 620 integrated graphics solution.

Memory and Cache

The Core i7-8650U supports DDR4 memory. In terms of cache, the Core i7-8650U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, 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 i7-8650U 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 1900.0 MHz, and it can boost up to 4.2 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 i7-8650U includes an integrated graphics solution called UHD 620. 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.

Benchmark Performance

The Core i7-8650U has the 346th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 18.55% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i7-7820HK CPU
