If you currently want to buy a Ryzen Pro 4000G alias Renoir, you either have to Complete PC acquire or get one Upgrade kit increase. We had a system from Arlt available on loan to find out how AMD’s latest APUs (Accelerated Processing Unit) do.
The chips are intended for the AM4 socket; consequently, they support DDR4 RAM. Our model is equipped with a Prime B550-Plus from Asus as the motherboard, which contains the Ryzen Pro 5 4650G, a six-core APU. If you want, you can also have the four-core Ryzen Pro 3 4350G or the eight-core Ryzen Pro 7 4750G installed. Arlt uses a Pure Rock 2 as a cooler, and the insulated housing – a Pure Base 500 – also comes from Be Quiet.
Arlt has installed a Focus GX-550 from Seasonic as a power supply, so the computer stays pleasantly quiet at all times – even though the two case fans (Pure Wings 2) are not the best that Be Quiet offers. For storage, Arlt chose a Seagate Firecuda 520, but the Ryzen Pro 4000G does not support PCIe Gen4, only PCIe Gen3. Compared to their mobile counterparts, however, more lanes are unlocked, so that an optional graphics card runs in x16 instead of x8 mode.
An advantage of the Ryzen Pro 4000G is obvious immediately after switching on: The power consumption when idling is a good 10 watts lower than with a Ryzen 3000, we measure 31 watts for the complete system. The reason is probably the monolithic design of the Renoir APUs instead of the chiplet approach of the Matisse CPUs. The Ryzen Pro 5 4650G consumes up to 73 watts under load, which is still below the 88 watts that AMD releases for a processor specified as a 65 watt chip.
In terms of CPU performance, the Ryzen Pro 5 4650G ranks somewhat below a six-core Ryzen 5 3600. While benchmarks like Blender show no significant differences, 7-Zip runs much faster on the Matisse CPU. This was to be expected, since the L3 cache was quartered with 8 MB instead of 32 MB. Despite this, the Ryzen Pro 5 4650G is very fast in everyday use, which is also due to the integrated graphics.
The Vega 7 has 448 shader units and enough bandwidth thanks to DDR4-3200 memory. Compared to the older Ryzen 5 3400G with Vega 11 and 704 lower clocked ALUs, it is 7 percent faster on average. This makes the Ryzen Pro 5 4650G perfectly suitable for 1080p gaming with less demanding games, although the acceleration of some filters is more relevant in office use.
With the Ryzen Pro 4000G, AMD has launched the most powerful processors with integrated graphics by far – the direct predecessors have only four instead of up to eight cores. A comparable Intel system at best has a similar CPU performance, but a much lower GPU speed. Thanks to the monolithic construction, the power consumption is also idle, which is below that of a Ryzen 3000 (Matisse).
Our test system is offered by Arlt for 730 euros. In addition to the Ryzen Pro 5 4650G, there are 16 GB of DDR4-3200 memory, a B550 board and a 500 GB SSD. For a surcharge of 55 euros, the manufacturer installs a 2 TB hard drive. An operating system is not available – Windows 10 Home OEM costs 80 euros and Windows 10 Pro is preinstalled for 110 euros. Arlt grants a two-year guarantee, in the event of a defect the PC can be picked up on request.
