AMD Ryzen 3 4300U vs AMD Ryzen 5 4680U

AMD Ryzen 3 4300U

► remove from comparison AMD R3 4300U

The AMD Ryzen 3 4300U is a processor for thin and light laptops based on the Renoir architecture. The 4300U integrates four cores based on the Zen 2 microarchitecture (quad core CPU). They are clocked at 2.7 (guaranteed base clock) to 3.7 GHz (Turbo) without SMT / Hyperthreading support (4 threads). 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 Ryzen 5 4000 CPUs (e.g., Ryzen 5 4600U), the Ryzen 3 only offers 4 cores and lower Turbo clock speeds.

In addition to the four CPU cores, the APU also has the Radeon RX Vega 5 integrated graphics card with 5 CUs and up to 1400 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 4 MB of Level 3 cache can be found on the chip. See our hub page on the Renoir Processors for more information.

Performance

The average 4300U in our database matches Intel Core i5-1035G4 and Core i5-11300H, both noticeably more power-hungry quad-core processors, in multi-thread performance. Technically a lower mid-range CPU, this Ryzen is light years ahead of Intel Pentiums and AMD Athlons that so many sub-US$500 laptops have.

Power consumption

The Ryzen 3 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are free to change to anything between 10 W and 25 W with performance and clock speeds changing correspondingly. The 7 nm TSMC process this AMD APU is built with makes for very good energy efficiency.

AMD Ryzen 5 4680U

► remove from comparison AMD R5 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 AMD Ryzen 7 4700U and Intel Core i5-10500H, the latter being a much more power-hungry CPU. This makes the Ryzen a more than decent CPU for most tasks, more demanding ones included.

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

While the TDP of the APU is specified at 15 watts, it consumed roughly 23 watts under prolonged load in our testing. The chip is a good fit for the thinner, lighter laptops provided an active cooling system is present.
