Intel Core i7-14700K vs Intel Core i5-7267U

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 i5-7267U

The Intel Core i5-7267U is a fast dual-core SoC for notebooks based on the Kaby Lake architecture and was announced in January 2017. The CPU has two processor cores clocked at 3.1-3.5 GHz (two cores also up to 3.5 GHz). The processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel Iris Plus Graphics 650 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still 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.

Performance

The performance of the 28-Watt CPU should be on par with the Core i7-7500U (2.7-3.5 GHz, no eDRAM, 15 Watts), but it should be a bit slower on practice due to the missing level 4 eDRAM and the lower TDP. This means the i5 is still one of the faster dual-core processors and should be sufficient for most scenarios. Some games might still require a real quad-core processor and therefore nit run perfectly on the dual-core processor, despite Hyper Threading.

Graphics

The integrated Intel Iris Plus 650 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1050 MHz and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Pro 550, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors 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 even further. Intel specifies the TDP with 28 Watts, which can be reduced to 23 Watts (cTDP Down) depending on the usage scenario. The TDP is pretty high compared to the common 15-Watt TDP for dual-core processors, but allows a better utilization of CPU and GPU Turbo.
