AMD Ryzen 5 5600G vs AMD Ryzen 7 7730U

AMD Ryzen 5 5600G

The AMD Ryzen 5 5600G is a Zen 3-based, desktop-grade APU featuring the Radeon Vega 7 graphics adapter. This Ryzen 5 was unveiled in H1 2021. It features six SMT-enabled CPU cores for 12 threads in total, running at 3.9 GHz to 4.4 GHz.

The CPU ships with AMD's Wraith Stealth cooler (as long as it's not an OEM version).

Architecture

Zen 3-based processors bring a moderate performance boost over Zen 2 generation CPUs. Core counts are left where they were before, while per-MHz performance is getting several percentage points higher.

Ryzen 5 5600G's CPU cores have access to 16 MB of L3 cache. The processor is compatible with DDR4-3200 RAM and has plenty of PCI-Express 3.0 lanes for connecting graphics cards, SSDs and other devices. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s, provided a sufficiently fast NVMe SSD is used. PCI-Express 4.0 spec is not supported here, since Ryzen 5 5600G is pretty much a laptop-grade SoC in disguise rather than a "proper" desktop chip, like a Ryzen 5 5600X.

You can replace this Ryzen with a faster CPU easily as it uses AMD's AM4 socket interface. Another way to get a performance boost would be to overclock the CPU, which is easy to do with AMD's very own software (many motherboard vendors offer overclocking software of their own as well).

Performance

The six Zen 3 cores will rip through most workloads rutlessly, more demanding ones included (like gaming and high-res video editing). Multi-thread benchmarks put the R5 5600G in the same league as the Core i5-10600K, Core i7-10700, Core i5-11600K, Core i7-11850H. A huge advantage of the Ryzen over the aforementioned alternatives is its decent integrated graphics adapter - more on this below.

Graphics

The Radeon RX Vega 7 iGPU has seven Compute Units (= 448 shaders) and runs at up to 1,900 MHz. It is casual gaming-friendly, allowing one to play most games at 900p / Low quality preset. On the other hand, there is no SUHD 4320p monitor support here, nor can the graphics adapter HW-decode AV1, the latest video codec.

Fast RAM is a prerequisite for decent gaming performance as the Vega has no memory of its own.

Power consumption

This Ryzen 5 is manufactured on TSMC's 7 nm process for great, as of early 2022, energy efficiency.

The chip has a default TDP of 65 W (also known as the long-term Power Limit). According to AMD's guidelines, that 65 W value can be reduced by PC makers significantly, the lower limit being 45 W, resulting in lower temperatures, lower clock speeds and lower performance. Either way, an active cooling solution is a must for a system built around this Ryzen.

AMD Ryzen 7 7730U

The AMD Ryzen 7 7730U is a processor for thin and light laptops based on the Cezanne generation. It is part of the second "Barcelo" refresh in early 2023 and offers the same specifications as the old Ryzen 7 5825U. The CPU integrates all eight cores based on the Zen 3 microarchitecture clocked at 2 (guaranteed base clock) to 4.5 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 7nm at TSMC.

The Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2 but stays behind the current Zen 4 based CPUs (e.g. 7040HS series).

Performance

The average 7730U in our database is in the same league as the Ryzen 7 5825U, Ryzen 7 6800U, Ryzen 7 PRO 6850U and also the Core i7-1360P, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 30 W, the ThinkPad E14 G5-21JSS05C00 is among the fastest laptops built around the 7730U that we know of. It can be almost 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 GPU with 8 CUs at up to 2000 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache (up from 8 MB at the 4800U) can be found on the chip.

The TDP of the APU is specified at 15 Watt (the 5825U was specified at 10 - 25W).
