Intel Core i7-14700K vs Intel Core i7-7500U vs Intel Core i9-14900K

Intel Core i7-14700K

The Intel Core i5-14700K is a desktop processor based on the Raptor Lake architecture, which inherits the 13th generation of Intel Core processors with minor improvements. The processor offers a base clock of 2.5 GHz or 3.4 GHz and reaches up to 5.6 GHz in Turbo. The basic CPU structure remains unchanged. The Intel Core i5-14700K features 8 P-cores and 12 E-cores, allowing up to 28 threads to be processed in parallel. The Intel Core i5-14700K still offers a freely selectable multiplier, which makes overclocking much easier. It is also based on the LGA 1700 socket, which was already introduced with Alder Lake.

Performance

Compared to the Intel Core i5-13700K, the IPC of the new Core i5-14700K has only been increased slightly. This means that the difference in performance is only due to the higher number of efficiency cores (12 vs. 8) and higher clock rates.

Graphics unit

Like the Intel Core i5-13700K, the Intel Core i5-14700K also has an integrated graphics unit. The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, nothing has changed with the Intel UHD Graphics 770.

Power consumption

The TDP of the Intel Core i5-14700K is 125 watts, with the option of consuming up to 253 watts in Turbo mode.

Intel Core i7-7500U

The Intel Core i7-7500U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.7 - 3.5 GHz and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz is very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1050 MHz). It is manufactured in an improved 14nm FinFET process (14nm+) at Intel. Compared to the old Skylake Core i7-6500U (2.5 - 3.1 GHz), the i7-7500U clock speed is up to 400 MHz higher.

Intel Core i9-14900K

The Intel Core i9-14900K is a high-end processor based on the Raptor Lake architecture, similar to the Intel Core i9-13900K last year. The base clock is 3.2 GHz and can reach up to 6 GHz under optimal conditions. The total of 32 threads are still divided into 8 P and 16 E cores. The 8 performance cores (P-cores) also offer hyperthreading, which means that a total of 32 threads can be processed simultaneously in conjunction with the 16 energy-efficient E-cores. As before, the K models continue to offer a freely selectable multiplier, which simplifies overclocking. The Intel Core i9-14900K uses the same CPU socket (LGA 1700) as the Intel Core i9-13900K. This means you don't necessarily need a new motherboard, as the 600 series chipsets support the new processors after a BIOS update. There is also still the option of using DDR4 for the RAM.

Performance

Compared to the Intel Core i9-13900K, the Core i9-14900K still offers 8 P-cores, which are relieved by 16 additional E-cores for demanding applications and thus ensure very high multi-thread performance. In comparison, however, the Intel Core i9-14900K can only gain a slight lead. The e-cores primarily take care of background applications. The hybrid architecture relies on the Intel Thread Director, which is responsible for the correct allocation of tasks. Meanwhile, the IPC could only be increased slightly. As an innovation with the Intel Core i9-14900K, the manufacturer is increasingly relying on AI, which is also used for overclocking. With one click in the Intel Extreme Utility, the tool checks the entire system and makes the necessary settings.

Graphics unit

Like the Intel Core i9-13900K, the Intel Core i9-14900K offers an integrated graphics unit. The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, nothing has changed with the Intel UHD Graphics 770.

Power consumption

The Intel Core i9-14900K is specified with a TDP of 125 watts, which corresponds to the PL1 value. In Boost mode, the processor's performance can increase to up to 253 watts (PL2). However, this requires very good cooling. Compared to the Intel Core i9-13900K, the specified power consumption does not increase if the limits are adhered to. The situation is different if the limits are deactivated. As this value depends on the overall system, we cannot make an exact statement on this.
