Intel Core i7-14700K vs Intel Core i5-7500

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 i5-7500

The Intel Core i5-7500 is a fast mid-range quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It offers four cores (no HyperThreading and therefore also only 4 threads at once) that run at 3.4 - 3.8 GHz.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

The performance of the i5-7500 is comparable to a mobile Core i7-7700HQ. Therefore, the performance is sufficient even for demanding applications and games.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1100 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency slightly. Intel still specifies the TDP with 65 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs but less than e.g. the Core i5-7600K (91 Watt).
