Intel Core i5-13450HX vs AMD Ryzen 5 PRO 6650HS

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.

AMD Ryzen 5 PRO 6650HS

The AMD Ryzen 5 PRO 6650HS is a processor for big (workstation) laptops based of the Rembrandt generation. The R5 6650HS integrates six of the eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured on the modern 6 nm TSMC process. The HS variant offers a 10 W reduced TDP and therefore a lower sustained performance than the H version. The 6650HS is the professional version of the consumer R5 6600HS with additional management features and the Microsoft Pluton Security processor.

The new Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip itself however, offers a lot of new features, like support for USB 4 (40 Gbps), PCI-E Gen 4, DDR5-4800MT/s or LPDDR5-6400MT/s, WiFi 6E, Bluetooth LE 5.2, DisplayPort 2, and AV1 decode.

In the 6000 series, AMD finally switched to the current RDNA 2 graphics architecture for the iGPU. The 6650HS only offers the slower Radeon 660M with 6 of the 12 CUs enabled and 1.9 GHz max. clock rate.

Performance

While we have not tested a single system built around the 6650HS as of August 2023, we have tested at least one system featuring the 6600HS, a chip with very similar specs (6 cores, 12 threads, up to 4.5 GHz, Zen 3+). Based on that, expect the 6650HS to be about as fast as the Ryzen 5 5600H, the Ryzen 7 5800U and also the Core i7-1260P, as far as multi-thread benchmark scores are concerned.

Your mileage may vary dependingon how high the CPU power limits are and how competent the cooling solution of your system is.

Power consumption

This Ryzen 5 has a default TDP (also known as the long-term power limit) of 35 W. Which is way too high to allow it to become a heart of a passively cooled tablet, laptop, mini-PC.

The APU is built with TSMC's 6 nm process for great, as of late 2022, energy efficiency.
