AMD Athlon 300U vs AMD Ryzen 7 5700G vs AMD Ryzen 7 PRO 4750U

AMD Athlon 300U

The AMD Athlon 300U is a mobile entry level dual core SoC that was announced in January 2019. It combines two Zen cores (with SMT / Hyperthreading so running 4 threads) clocked at 2.4 - 3.3 GHz with a Radeon RX Vega 3 graphics card with 3 CUs (192 Shaders) clocked at up to 1000 MHz. Specified at 15 Watt TDP, the SoC is intended for thin mid-range laptops. It is quite similar to the AMD Ryzen 3 3200U (2.6 - 3.5 GHz).

Compared to the Picasso APUs of the Ryzen 3000 series, the Athlon 300U is still based on the first generation of the 2000 series. Only the PRO variant is based on the new Zen+ microarchitecture that should lead to a 3% IPS (performance per clock) improvement.

The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

In contrast to the faster quad-core Picasso APUs, the Athlon 300U only supports 3 instead of 4 displays in total.

Performance wise, the Athlon 300 should be slightly slower than the Ryzen 3 2200U (2.5 - 3.4 GHz Dual Core with SMT).

AMD Ryzen 7 5700G

The AMD Ryzen 7 5700G is a desktop APU with 8 cores and part of the Cezanne product family. The 8 cores are based on the Zen 3 architecture and can clock between 3.8 to 4.6 GHz. Thanks to Simultaneous Multithreading (SMT), the CPU supports up to 16 threads at once. At time of the launch, the 5700G is the fastest 8-core-CPU with an iGPU from AMD.

The integrated AMD Radeon RX Vega 8 is currently one of the fastest iGPUs and capable of 1080p gaming at low details.

Performance

The 5700G delivers very serviceable multi-thread performance, as of mid 2022, trading blows with upper mid-range chips such as the Ryzen 7 3700X and the Core i5-12500H. Besides, the consumer is officially allowed to overclock the thing, creating a bit of a performance gain out of thin air. Find out more by reading our full Ryzen 7 5700G review.

Power consumption

This Ryzen 7 series APU has a default TDP, also known as the long-term power limit, of 65 W. PC makers are free to reduce that somewhat with 45 W being the minimum AMD-recommended value. Clock speeds and performance would take a hit as a result.

The R7 5700G is built with TSMC's 7 nm manufacturing process for average, as of mid 2023, energy efficiency.

AMD Ryzen 7 PRO 4750U

The AMD Ryzen 7 PRO 4750U is a processor for thin and light laptops based on the Renoir architecture. The PRO 4750U integrates all eight cores based on the Zen 2 microarchitecture. They are clocked at 1.7 (guaranteed base clock) to 4.1 GHz (Turbo) with SMT / Hyperthreading support (16 threads). The chip is manufactured in the modern 7 nm process at TSMC and partly thanks to it AMD advertises a 2x improved performance per Watt for the Renoir chips. Compared to the faster consumer R7 4800U, the PRO 4750U offers lower boost clock speeds.

The PRO processors offer a range of business features like hardware security (e.g., AMD Memory Guard), manageability (e.g., support for Microsoft Endpoint Manager), and longer availability and software stability. 

Thanks to the SMT support, the Ryzen 7 PRO 4750U should be slightly faster in some workloads than the consumer Ryzen 7 4700U. However, as the base clock speed is lower, there can be some workloads that are executed slower.

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 TDP of the APU is specified at 15 Watt (default) and can be configured from 10 to 25 Watt by the laptop vendor. That means the chip is intended for thin and light laptops (but with fans).
