About the Intel Core i7-5557U CPU
The Intel Core i7-5557U is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q1 2015 with a suggested retail price of $426. It is part of Intel's Core i7 lineup, which is based on the Broadwell-U microarchitecture. The i7-5557U is compatible with Intel BGA 1168 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel Iris 6100 integrated graphics solution.
Memory and Cache
The Core i7-5557U supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-5557U 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 i7-5557U 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 3.1 GHz, 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 i7-5557U includes an integrated graphics solution called Intel Iris 6100. 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 i7-5557U has the 425th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 11.96% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 4,423 score and $426 launch price (MSRP) gives it a performance per dollar of 10.38. This is the 191st best in value for the 3DMark 11 Perf. Physics benchmark.
About the AMD Ryzen Z1 Extreme CPU
The AMD Ryzen Z1 Extreme is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2023. It is part of AMD's Ryzen Z1 lineup, which is based on the Zen 4 microarchitecture. The Z1 Extreme is compatible with AMD Socket FP8 motherboards and is fabricated on TSMC's 4 nm manufacturing process. It features the Radeon 780M integrated graphics solution.
Memory and Cache
The Ryzen Z1 Extreme supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen Z1 Extreme 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.
