Intel Core Ultra 7 265KF Vs Intel Core i7-14700KF

The Intel Core Ultra 7 265KF is built on a newer 3nm Arrow Lake-S architecture, offering better power efficiency and performance per watt than the 10nm Raptor Lake Refresh-based i7-14700KF

Both CPUs have 20 cores (8 P-cores + 12 E-cores), but the i7-14700KF supports Hyper-Threading on P-cores, resulting in 28 threads versus 20 threads on the Ultra 7 265KF

The Ultra 7 265KF features a higher base clock (3.9 GHz) compared to the i7-14700KF (3.4 GHz), while the i7-14700KF has a slightly higher turbo boost (5.6 GHz vs. 5.5 GHz)

Both CPUs support PCIe 5.0 and DDR5 memory, but the Ultra 7 265KF supports faster DDR5-6400 and up to 192GB, compared to DDR5-5600 on the i7-14700KF

The Ultra 7 265KF has a larger L2 cache (36 MB vs. 28 MB), while the i7-14700KF offers a larger L3 cache (33 MB vs. 30 MB)

The Ultra 7 265KF uses the new LGA 1851 socket, requiring a new motherboard, while the i7-14700KF is compatible with the existing LGA 1700 platform

The Ultra 7 265KF is more power efficient and runs cooler, making it suitable for quieter and more energy-efficient builds

The i7-14700KF’s higher thread count gives it an edge in highly parallel workloads like rendering and compilation
