About the Intel Core i7-1355U CPU

The Intel Core i7-1355U is a 10-core (12-thread) processor built for the mobile CPU market. It launched in Q1 2023 with a suggested retail price of $469. It is part of Intel's Core i7 lineup, which is based on the Raptor Lake-U microarchitecture. The i7-1355U is compatible with Intel BGA 1744 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe Graphics 96EU integrated graphics solution.

Memory and Cache

The Core i7-1355U supports DDR4-3200, DDR5-5200 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-1355U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 12 MB.

Cores and Clock Speeds

The Core i7-1355U features 10 total cores which can process 12 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 10 cores consist of 2 P-Cores and 8 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 1700.0 MHz, and it can boost up to 5.0 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 i7-1355U includes an integrated graphics solution called Iris Xe Graphics 96EU. 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 i7-1355U has the 170th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 35.54% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 13,147.5 score and $469 launch price (MSRP) gives it a performance per dollar of 28.03. This is the 128th best in value for the 3DMark 11 Perf. Physics benchmark.
