Benchmark Performance
The Core Ultra 7 255H has the 75th best 3DMark 11 Performance Physics score among the 767 benchmarked CPUs in our database. It achieves 55.42% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.
About the AMD Ryzen Z1 Extreme CPU
The AMD Ryzen Z1 Extreme is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2023. It is part of AMD's Ryzen Z Series lineup, which is based on the Zen 4 microarchitecture. The Z1 Extreme is compatible with AMD Socket FP8 motherboards and is fabricated on TSMC's 4 nm manufacturing process. It features the Radeon 780M integrated graphics solution.
Memory and Cache
The Ryzen Z1 Extreme supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen Z1 Extreme 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 1 MB, 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 Z1 Extreme 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 3.3 GHz, and it can boost up to 5.1 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 Ryzen Z1 Extreme includes an integrated graphics solution called Radeon 780M. 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 Ryzen Z1 Extreme has the 99th best 3DMark 11 Performance Physics score among the 767 benchmarked CPUs in our database. It achieves 49.50% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.
