AMD Ryzen 7 1800X vs AMD Athlon 300U

AMD Ryzen 7 1800X

The AMD Ryzen 7 1800X is a fast desktop processor with 8 cores and SMT (16 threads) that was introduced in early 2017. It is based on the new Zen architecture and it is the fastest model at the time of announcement.

The CPU cores clock from 3.6 base speed up to 4.1 GHz (XFR). The 2-core Turbo is specified at 4 GHz and using all 8 cores, the CPU can reach up to 3.7 GHz. Therefore, the CPU offers 200 MHz more than the Ryzen 7 1700X.

The performance in applications that can make use of all 8 cores is very competitive to high end Intel CPUs at a very good price point. However, non optimized apps like many games can't make full use of the new architecture.

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).
