About the Intel Core 3 N355 CPU

The Intel Core 3 N355 is a 8-core (8-thread) processor built for the mobile CPU market. It launched in Q1 2025. It is part of Intel's Core 3 lineup, which is based on the Alder Lake-N microarchitecture. The 3 N355 is compatible with Intel BGA 1264 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.

Memory and Cache

The Core 3 N355 supports DDR4-3200, DDR5 memory and features a single-channel memory controller, allowing it to utilize 1 memory modules simultaneously. In terms of cache, the Core 3 N355 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 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 6 MB.

Cores and Clock Speeds

The Core 3 N355 features 8 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 100.0 MHz, 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 locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core 3 N355 includes an integrated graphics solution called UHD Graphics 770. 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 3 N355 has the 293rd best 3DMark 11 Performance Physics score among the 768 benchmarked CPUs in our database. It achieves 25.92% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.

About the Intel Core Ultra 5 115U CPU

The Intel Core Ultra 5 115U is a 8-core (10-thread) processor built for the mobile CPU market. It launched in Q4 2023. It is part of Intel's Ultra 5 lineup, which is based on the Meteor Lake microarchitecture. The Ultra 5 115U is compatible with Intel BGA 2049 motherboards and is fabricated on Intel's 7 nm manufacturing process. It features the Arc Xe-LPG 48EU integrated graphics solution.

Memory and Cache

The Core Ultra 5 115U supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core Ultra 5 115U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 112 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 10 MB.

Cores and Clock Speeds

The Core Ultra 5 115U features 8 total cores which can process 10 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 8 cores consist of 2 P-Cores and 6 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 1500.0 MHz, and it can boost up to 4.2 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.
