AMD Ryzen 5 4680U vs AMD Ryzen 5 5600HS vs AMD Ryzen 5 4600H

AMD Ryzen 5 4680U

The AMD Ryzen 5 4680U is a semi-custom APU of the Renoir family designed for Microsoft devices. The 4680U integrates six CPU cores based on the Zen 2 microarchitecture clocked at 2.2 GHz (base) to 4 GHz (Boost) with SMT support for a total 12 threads. The two advantages a 4680U has over the older Ryzen 5 4600U are its higher base clock speed and a faster iGPU.

Architecture

The chip is manufactured on the modern 7 nm TSMC process and in part thanks to this fact, AMD advertises a 2x performance per watt improvement over the 12 nm Ryzen 3000 mobile processors. The built-in dual-channel memory controller supports LPDDR4-4266 RAM. Furthermore, 8 MB of L3 cache can be found on the chip.

Just like the other mobile Ryzen 4000 CPUs, a 4680U supports PCI-Express 3.0. Please go to our Renoir processor hub page for additional information on the product family.

Performance

Multi-thread performance is most comparable to the Ryzen 7 4700U and the Core i5-10500H, the latter being a much more power-hungry chip. This makes the Ryzen a more than decent CPU for most tasks, as of early 2022.

Graphics

In addition to the six CPU cores, the APU also integrates a DX 12 compatible Radeon RX Vega 7 graphics adapter with 7 CUs (448 unified shaders) at up to 1,500 MHz. The Vega iGPU will have no trouble HW-decoding AVC, HEVC and VP9 videos, but the newer AV1 codec will only be decoded via software. In terms of gaming, we are looking at an MX150-level performance. Pretty much all games released in 2020 can be played on low to medium settings in 720p on this graphics adapter.

Power consumption

This Ryzen 5 series chip has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop makers - Microsoft, in this case - are free to change to anything between 10 W and 25 W, with clock speeds and performance changing accordingly as a result. Indeed, we saw the CPU consume roughly 23 watts when subjected to our usual stress testing routine.

The 7 nm TSMC process this Ryzen is built with makes for very decent, as of mid 2022, energy efficiency.

AMD Ryzen 5 5600HS

The AMD Ryzen 5 5600HS is a processor for big (gaming) laptops based on the Cezanne generation. The R5 5600H integrates six of the eight cores based on the Zen 3 microarchitecture. They are clocked at 3 GHz (guaranteed base clock) to 4.2 GHz (Turbo) and support SMT / Hyperthreading (12 threads). The chip is manufactured in the modern 7 nm process at TSMC. Compared to the 5600H (up to 52 W), the 5600HS is configured to a TDP of 35W.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

With the increased clock speed and IPC improvements thanks to Zen 3, the Ryzen 5 5600H should be clearly faster than the lower clocked Ryzen 7 4600H.

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6  integrated graphics card with 6 CUs and up to 1800 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache can be found on the chip.

The TDP of the APU is specified at 35 Watt and therefore also suited for thin gaming laptops.

AMD Ryzen 5 4600H

The AMD Ryzen 5 4600H is a mobile SoC for big laptops based on the Renoir architecture. The 4600H integrates six of the eight cores based on the Zen 2 microarchitecture. They are clocked at 3 (guaranteed base clock) to 4 GHz (Turbo) and support SMT / Hyperthreading (12 threads).

In addition to the six CPU cores, the APU also integrates a Radeon RX Vega 6 integrated graphics adapter with 6 CUs and up to 1500 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 8 MB level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

Performance

The average 4600H in our database matches the Intel Core i7-10875H and even the Core i9-10885H, both significantly more costly chips, in multi-thread performance, giving this Ryzen an outrageously high price-to-performance ratio.

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

Power consumption

The Ryzen 5 chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are free to change to anything between 35 W and 54 W with clock speed and performance changing accordingly as a result. Either way, a high-performance cooling solution is a must for a CPU like this.

The 7 nm TSMC process this APU is built with makes for better-than-average, as of early 2022, energy efficiency.
