About the Intel Core i7-1255U CPU
The Intel Core i7-1255U is a 10-core (12-thread) processor built for the mobile CPU market. It launched in Q1 2022. It is part of Intel's Core i7 lineup, which is based on the Alder Lake-U microarchitecture. The i7-1255U is compatible with Intel BGA 1744 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe 96EU integrated graphics solution.
Memory and Cache
The Core i7-1255U supports DDR4-3200, DDR5-4800 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-1255U 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 i7-1255U 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 4.7 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 i7-1255U includes an integrated graphics solution called Iris Xe 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
The Core i7-1255U has the 143rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 40.31% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the AMD Ryzen 7 6800U CPU
The AMD Ryzen 7 6800U is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q1 2022. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 3+ microarchitecture. The 6800U is compatible with AMD Socket FP7 motherboards and is fabricated on TSMC's 6 nm manufacturing process. It features the Radeon 680M integrated graphics solution.
Memory and Cache
The Ryzen 7 6800U supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 6800U 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 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 16 MB.
Cores and Clock Speeds
The Ryzen 7 6800U features 8 total cores which can process 16 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.7 GHz, and it can boost up to 4.7 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.
