Intel Core Ultra 7 255H
The Core Ultra 7 255H is a 16 core CPU from Intel released in 2025. This chip has an average overall score with 2788 points in our CPU benchmark. Our gaming benchmark shows that this CPU is a good processor for gaming, with a score of 3457 points. As for multitasking and heavy workloads, the Core Ultra 7 255H scores 2584 points and 2521 points respectively. Indeed, this is an average rating for very heavy workloads.
The Core Ultra 7 255H has 16 cores and 16 threads. This chip has no simultaneous multithreading support, as it has the same number of cores as threads. This Intel CPU has a clock speed of 2 GHz and a turbo speed of 5.1 GHz : a higher clock speed that can be reached when thermals and power delivery allow.
As for memory, the Core Ultra 7 255H makes use of DDR5-8400 memory. The faster the memory, the better. Faster memory means that the CPU doesn't have to wait to get the data it needs. It can accommodate a maximum of 128 GiB of memory. Furthermore, this chip can handle up to 2 channels of RAM, a multichannel memory architecture allows for higher data transfer between the CPU and the memory. However, to take advantage of this, you must have enough memory slots filled. Error correcting memory is not supported on this processor.
In terms of cache, the Core Ultra 7 255H has 28 MiB of level 2 cache and 24 MiB of level 3 cache. This is a fast memory located close to the processor, which stores copies of frequently used data from main memory.
It has a total of 28 PCIe lanes.
