AMD Ryzen 5 2600 vs AMD Athlon 300U vs AMD Ryzen Embedded R1606G

AMD Ryzen 5 2600

The AMD Ryzen 5 2600 is a six-core desktop processor that can handle twelve threads simultaneously thanks to Simultaneous Multithreading (SMT). This technology is equivalent to Intel's Hyper-Threading. Launched in April 2018, the Ryzen 5 2600 is the second fastest Ryzen 5 processor and is much more economical than its flagship sibling. The Ryzen 5 2600 has a 65 W TDP, which is nearly 40% more efficient than the 95 W TDP Ryzen 5 2600 X. This energy efficiency comes at a cost to performance though.

The Ryzen 5 2600 has a base clock speed of 3.4 GHz, which can be boosted by Extended Frequency Range (XFR) up to 3.9 GHz. The power gain is still high in multi-threaded applications, although this is some way off the Ryzen 5 2600X. The Ryzen 5 2600 benefits from AMD's new Zen+ architecture, with a greater number of instructions per cycle (IPC) and higher clock speeds than last year's Zen chips. The Ryzen 5 2600's six cores are divided into two clusters that are connected by Infinity Fabric, a subset of HyperTransport. Each cluster has its own L3 cache.

The Ryzen 5 2600 has good performance in games. Moreover, the Ryzen 5 2600 has a higher base clock than the Ryzen 7 2700. Seeing as many games currently lack multi-core support, this means that the Ryzen 5 2600 performs better than its technically superior sibling.

Detailed information, benchmarks and values can be found in our review of the Ryzen 5 2600.

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 Embedded R1606G

The AMD Ryzen Embedded R1606G is a dual-core SoC designed for embedded systems that was announced in March 2019. It is similar to the Ryzen 3 3200U (or the 2200U with slightly increased clock speed) and based on the first generation of the Zen architecture. The Ryzen features two Zen cores with support for the thread-doubling SMT tech, clocked at 2.6 GHz - 3.5 GHz. The built-in Radeon RX Vega 3 iGPU has 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops.

In comparison to the faster Ryzen 3000 CPUs, the 3200U and therefore the R1606G is not using the newer Zen+ microarchitecture and is still manufactured in 14nm. Compared to the old Ryzen 3 2200U, the 3200U and R1606G therefore only offers a 100 MHz higher clock speed.

The R1606G is compatible with single-channel or dual-channel DDR4-2400 RAM. Please go to our Raven Ridge launch article for details on the architecture and more.
