Intel Core Ultra 7 255HX
The Core Ultra 7 255HX is a 20 core CPU from Intel released in 2025. This chip has an incredible overall score with 14832 points in our CPU benchmark. Our gaming benchmark shows that this CPU is an incredible processor for gaming, with a score of 14976 points. As for multitasking and heavy workloads, the Core Ultra 7 255HX scores 14778 points and 14762 points respectively. Indeed, this is an incredible rating for very heavy workloads.
The Core Ultra 7 255HX has 20 cores and 20 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 2.4 GHz and a turbo speed of 5.2 GHz : a higher clock speed that can be reached when thermals and power delivery allow.
As for memory, the Core Ultra 7 255HX makes use of DDR5-6400 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 256 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 255HX has 36 MiB of level 2 cache and 30 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.
This CPU has fast connectivity with support for PCI-Express Gen 5. The faster the PCIe link, the better. This allows for better performance with GPUs and NVME SSDs. It has a total of 24 PCIe lanes.
