About the Intel Core i5-8257U CPU

The Intel Core i5-8257U is a 4-core (8-thread) processor built for the mobile CPU market. The i5-8257U is compatible with Socket 1528 FCBGA motherboards and is fabricated on a 14 nm manufacturing process. It features the Intel Iris Plus Graphics 645 integrated graphics solution.

Memory and Cache

In terms of cache, the Core i5-8257U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 256 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, 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 i5-8257U 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 1400.0 MHz, and it can boost up to 3900.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Core i5-8257U includes an integrated graphics solution called Intel Iris Plus Graphics 645. 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 i5-8257U has the 319th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 21.26% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core m5-6Y54 CPU

The Intel Core m5-6Y54 is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2015 with a suggested retail price of $281. It is part of Intel's Core m5 lineup, which is based on the Skylake-Y microarchitecture. The m5-6Y54 is compatible with Intel BGA 1515 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel HD 515 integrated graphics solution.

Memory and Cache

The Core m5-6Y54 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core m5-6Y54 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 4 MB.

Cores and Clock Speeds

The Core m5-6Y54 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 1100.0 MHz, and it can boost up to 2.7 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 m5-6Y54 includes an integrated graphics solution called Intel HD 515. 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 & Value

The Core m5-6Y54 has the 564th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 6.84% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 2,529 score and $281 launch price (MSRP) gives it a performance per dollar of 9. This is the 202nd best in value for the 3DMark 11 Perf. Physics benchmark.
