Intel Core i5-13450HX vs Intel Core i7-13700K

Intel Core i5-13450HX

The Intel Core i5-13450HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023. The CPU integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 4 Gracemont efficiency cores without HyperThreading. The P-Cores clock between 2.4 GHz (base) up to 4.6 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.8 and 3.4 GHz. All cores can access the combined 20 MB L3 cache (compared to the 36 MB of the i9 models).

Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i5).

Performance

While we have not tested a single system built around the 13450HX as of August 2023, we have tested several systems featuring the Core i5-12600K, a CPU with very similar specs (six P-cores mated to four E-cores, both running at insignificantly faster clock speeds than what the 13450HX has). Based on that, we expect the 13450HX to be 10% to 15% behind the Ryzen 7 7840HS and the Ryzen 9 7940HS, as far as multi-thread benchmark scores are concerned.

Your mileage may vary depending on how competent the system's cooling solution is and how high the CPU power limits are.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its Turbo power consumption is not supposed to go over 157 W and its "base" power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to extract as much performance out of the chip as possible.

The i5-13450HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.

Intel Core i7-13700K

The Intel Core i7-13700K is a high-end CPU based on the current Raptor Lake architecture, which was introduced in September 2022. The base clock is 3.4 GHz and can reach up to 5.4 GHz under optimal conditions. The total of 16 cores are divided into 8 P-cores and 8 E-cores, which we already know from the Alder Lake architecture. Compared to the Intel Core i7-12700K, however, the number of E-cores has been doubled, meaning that the Intel Core i7-13700K now offers 24 threads. As usual, the K models continue to offer a freely selectable multiplier, which simplifies overclocking. In addition, all new Raptor Lake processors can be operated on the existing Socket 1700 motherboards.

Performance

Compared to the Intel Core i7-12700K, the Core i7-13700K still offers 8 P-cores, but these are to be relieved by 8 additional E-cores for demanding applications. 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. Compared to Alder Lake, the number of e-cores has been doubled, which significantly improves multi-thread performance in combination with a further increase in IPC. If all requirements are met, Intel Turbo Boost 3.0 can increase the clock rate of the P-cores to up to 5.4 GHz. The E-cores can also be overclocked and reach a maximum of 3.4 GHz.

Graphics

Like the Intel Core i7-12700K, the Intel Core i7-13700K offers an integrated graphics unit (iGPU). The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, not much has changed with the new Intel UHD Graphics 770.

Power Consumption

The Intel Core i7-13700K 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 good cooling. If all restrictions are deactivated in the BIOS, the PL2 value is not restricted by a Tau value.
