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.
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.
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.
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.
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.
The AMD Ryzen 7 4700U is a processor for thin and light laptops based on the Renoir architecture. The 4700U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 2 (guaranteed base clock) to 4.1 GHz (Turbo). There is no support for the thread-doubling SMT tech. The chip is manufactured on the modern 7 nm TSMC process and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster R7 4800U, the 4700U offers slightly lower clock speeds and no support for SMT / Hyperthreading.
In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 7 integrated graphics card with 7 CUs and up to 1600 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.
The average 4700U in our database proves to be a rather competent little processor. It trades blows with the much more power-hungry Intel Core i7-10750H, as far as multi-thread benchmark scores are concerned. While it fails to get far enough away from the more affordable Ryzen 5 4600U, this Ryzen 7 is still a good CPU for most tasks.
Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.
The Ryzen 7 4700U is a 15 W chip. However, laptop makers are allowed to change that value to anything between 10 W and 25 W, with clock speeds and long-term performance changing accordingly as a result. By going for the lowest value, it is possible to build a passively cooled system around the APU.
The fairly modern 7 nm TSMC process this Ryzen is manufactured on makes for above average, as of mid 2022, energy efficiency.
