About the Intel Atom x5-Z8550 CPU

The Intel Atom x5-Z8550 is a 4-core (4-thread) processor built for the mobile CPU market. The x5-Z8550 is compatible with Socket 1380 BGA motherboards and is fabricated on a 14 nm manufacturing process.

Memory and Cache

In terms of cache, the Atom x5-Z8550 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 224 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 0 MB.

Cores and Clock Speeds

The Atom x5-Z8550 features 4 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 1440.0 MHz, and it can boost up to 2400.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Atom x5-Z8550 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance

The Atom x5-Z8550 has the 644th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 4.70% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Celeron 3865U CPU

The Intel Celeron 3865U is an end-of-life 2-core (2-thread) processor built for the mobile CPU market. It launched in Q1 2017 with a suggested retail price of $107. It is part of Intel's Celeron lineup, which is based on the Kaby Lake-U microarchitecture. The 3865U is compatible with Intel BGA 1356 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel HD Graphics 610 integrated graphics solution.

Memory and Cache

The Celeron 3865U supports DDR4-2133, DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Celeron 3865U 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 2 MB.

Cores and Clock Speeds

The Celeron 3865U features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1800.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Celeron 3865U includes an integrated graphics solution called Intel HD Graphics 610. 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 Celeron 3865U has the 623rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 5.15% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 1,906 score and $107 launch price (MSRP) gives it a performance per dollar of 17.81. This is the 167th best in value for the 3DMark 11 Perf. Physics benchmark.
