Intel Core Ultra 9 275HX
The Core Ultra 9 275HX is a 24 core CPU from Intel released in 2025. This chip has an incredible overall score with 15155 points in our CPU benchmark. Our gaming benchmark shows that this CPU is an incredible processor for gaming, with a score of 14741 points. As for multitasking and heavy workloads, the Core Ultra 9 275HX scores 15354 points and 15488 points respectively. Indeed, this is an incredible rating for very heavy workloads.
The Core Ultra 9 275HX has 24 cores and 24 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 2.7 GHz and a turbo speed of 5.4 GHz : a higher clock speed that can be reached when thermals and power delivery allow.
As for memory, the Core Ultra 9 275HX 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 9 275HX has 40 MiB of level 2 cache and 36 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.
