Intel Core i7-7700 vs Intel Core i5-14600K vs Intel Core i7-7700K

Intel Core i7-7700

The Intel Core i7-7700 is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the 65 Watt consumer Kaby-Lake-H series at the time of the announcement. The faster CPUs, like the Core i7-7700K, are specified with 91 Watt. Besides four cores including Hyper-Threading (8 threads) support running at 3.6 - 4.2 GHz, the processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.

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.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency slightly.

Intel Core i5-14600K

The Intel Core i5-14600K is a modern 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 3.5 GHz and reaches up to 5.3 GHz in Turbo. The basic CPU structure remains unchanged. This means that the Intel Core i5-14600K also has 6 P-cores and 8 E-cores, which means that up to 20 threads can be processed in parallel. The Intel Core i5-14600K still offers a freely selectable multiplier, which makes overclocking much easier. The LGA 1700 socket, which was already introduced with Alder-Lake, is also used as the basis.

Performance

Compared to the Intel Core i5-13600K , the IPC of the new Core i5-14600K has only been increased slightly. This means that the difference in performance is also only slight. The hybrid architecture relies on the Intel Thread Director, which is responsible for the correct allocation of tasks. As a further innovation, 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 i5-13600K, the Intel Core i5-14600K 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 i5-14600K is 125 watts, with the option of consuming up to 181 watts in Turbo mode. If all limits are removed, the energy requirement rises to up to 240 watts. For cooling, we recommend a powerful air cooler or a 240 AiO.

Intel Core i7-7700K

The Intel Core i7-7700K is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the consumer Kaby-Lake-H series at the time of the announcement. Besides four cores including Hyper-Threading (8 threads) support running at 4.2 - 4.5 GHz, the processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400).

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

Thanks to the 200 (base) and 300 MHz (Boost) higher clock speed, respectively, the i7-7700K is a few percent faster than the old Skylake Core i7-6700K that offers the same per-MHz performance. Therefore, it is a very fast quad-core CPU that offers sufficient performance for all tasks.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1150 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 91 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs.
