About the Intel Core i7-8559U CPU

The Intel Core i7-8559U is a 4-core (8-thread) processor built for the mobile CPU market. It launched in Q2 2018. It is part of Intel's Core i7 lineup, which is based on the Kaby Lake-U Refresh microarchitecture. The i7-8559U is compatible with Intel BGA 1356 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Iris Pro Plus integrated graphics solution.

Memory and Cache

The Core i7-8559U supports DDR4 memory. In terms of cache, the Core i7-8559U 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 i7-8559U 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 2.7 GHz, and it can boost up to 4.5 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 i7-8559U includes an integrated graphics solution called Iris Pro Plus. 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 i7-8559U has the 271st best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 24.77% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i7-3940XM CPU

The Intel Core i7-3940XM is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q3 2012. It is part of Intel's Core i7 Extreme lineup, which is based on the Ivy Bridge microarchitecture. The i7-3940XM is compatible with Intel Socket G2 (988B) motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the Intel HD 4000 integrated graphics solution.

Memory and Cache

The Core i7-3940XM supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-3940XM 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 i7-3940XM 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 3.0 GHz, and it can boost up to 3.9 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Core i7-3940XM includes an integrated graphics solution called Intel HD 4000. 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 i7-3940XM has the 277th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 24.42% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
