About the Intel Core i7-7660U CPU
The Intel Core i7-7660U is a 2-core (4-thread) processor built for the mobile CPU market. The i7-7660U is compatible with FCBGA1356 motherboards and is fabricated on a 14 nm manufacturing process. It features the Intel Iris Plus Graphics 640 integrated graphics solution.
Memory and Cache
In terms of cache, the Core i7-7660U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 4 MB.
Cores and Clock Speeds
The Core i7-7660U features 2 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2500.0 MHz, and it can boost up to 4000.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.
Integrated Graphics
The Core i7-7660U includes an integrated graphics solution called Intel Iris Plus Graphics 640. 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 i7-7660U has the 402nd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 14.14% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Core m5-6Y57 CPU
