About the Intel Core Ultra 7 155H CPU
The Intel Core Ultra 7 155H is a 16-core (22-thread) processor built for the mobile CPU market. It launched in Q4 2023. It is part of Intel's Ultra 7 lineup, which is based on the Meteor Lake microarchitecture. The Ultra 7 155H is compatible with Intel BGA 2049 motherboards and is fabricated on Intel's 7 nm manufacturing process. It features the Arc Xe-LPG 128EU integrated graphics solution.
Memory and Cache
The Core Ultra 7 155H 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 7 155H 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 24 MB.
Cores and Clock Speeds
The Core Ultra 7 155H features 16 total cores which can process 22 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 6 P-Cores and 10 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 3.8 GHz, and it can boost up to 4.8 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 Ultra 7 155H includes an integrated graphics solution called Arc Xe-LPG 128EU. 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 Ultra 7 155H has the 68th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 55.72% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Pentium Gold 5405U CPU

It is part of Intel's Pentium Gold lineup, which is based on the Whiskey Lake microarchitecture. The Gold 5405U is compatible with Intel BGA 1528 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 620 integrated graphics solution.
Memory and Cache
The Pentium Gold 5405U supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Pentium Gold 5405U 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 Pentium Gold 5405U 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 2.3 GHz. 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 Pentium Gold 5405U includes an integrated graphics solution called UHD Graphics 620. 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 Pentium Gold 5405U has the 514th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database.
