Intel Core Ultra 5 245 vs Intel Core Ultra 5 245KF

Intel Core Ultra 5 245

The Intel Core Ultra 5 245 is an Arrow Lake-based desktop processor with 14 cores in two clusters. The 6 performance cores clock at up to 5.1 GHz and the 8 smaller efficiency cores at up to 4.5 GHz.

The CPU performance is slightly above the older Core i5-14600K and therefore also suited for demanding applications and 3D gaming. Thanks to the 5,1 GHz of the performance cores, the single core performance is excellent.

The integrated GPU is just called Intel Graphics and offers 4 Xe cores wit up to 1.9 GHz.

The Arrow Lake-S chips are composed of several chiplets. The CPU part is manufactured at TSMC in the modern N3B (3nm) process, the GPU also comes from TSMC in the N5P process. The SoC and I/O tile are manufactured in the older TSMC N6 process. The base tile is manufactured by Intel in the 22nm process and carries the individual chiplets thanks to Fovero's 3D packaging.

The TDP is specified at 65 watts (long-term) to 121 watts (Turbo).

Intel Core Ultra 5 245KF

The Intel Core Ultra 7 245KF is an Arrow Lake-based desktop processor with 14 cores in two clusters. The 6 performance cores clock at up to 4.2 - 5.2 GHz and the 8 smaller efficiency cores at up to 3.6 - 4.6 GHz. All CPU cores can use the 24 MB Smart Cache (L3).

The Arrow Lake-S chips are composed of several chiplets. The CPU part is manufactured at TSMC in the modern N3B (3nm) process, the GPU also comes from TSMC in the N5P process. The SoC and I/O tile are manufactured in the TSMC N6 process. The base tile is manufactured by Intel in the 22nm process and carries the individual chiplets thanks to Fovero's 3D packaging.

Compared to the similar Core Ultra 7 245K, the 245KF does not integrates a Intel Graphics called 4-core iGPU and also lacks vPro features.

The TDP is specified at 125 watts (long-term) to 159 watts (turbo).
