About the Intel Core i5-8250U CPU
The Intel Core i5-8250U 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 i5 lineup, which is based on the Kaby Lake-U Refresh microarchitecture. The i5-8250U 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 i5-8250U supports DDR4 memory. In terms of cache, the Core i5-8250U 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 6 MB.
Cores and Clock Speeds
The Core i5-8250U 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 1600.0 MHz, and it can boost up to 3.4 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 i5-8250U 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 i5-8250U has the 375th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 16.97% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
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
