AMD Athlon 5350 APU On Linux

In terms of Linux compatibility for the Athlon 5350 and other socketed Kabini APUs on Linux, everything appears to be in shape when using Ubuntu 14.04 LTS with the Linux 3.13 kernel. With Kabini APUs not being new and the GCN graphics support finally coming together nicely in recent months on the RadeonSI Gallium3D driver, it was a decent out-of-the-box experience using this hardware on Ubuntu Linux except that with Ubuntu 14.04's Linux 3.13 kernel there still isn't DPM by default for GCN hardware... It's a performance problem, but easily rectifiable and more on that later.

In articles to come I'll be benchmarking the open-source RadeonSI Gallium3D vs. closed-source Catalyst driver performance, compiler tuning/comparisons, benchmarks on other kernels and distributions, and various other tests from the Athlon 5350.

For the initial AMD Athlon 5350 Linux benchmarking I compared the performance against a few other low-power, entry-level systems I've been tested in recent days from the same Ubuntu 14.04 LTS snapshot:

- Intel Atom E3825 via the AAEON EMB-BT1 motherboard. The Atom E3825 is a dual-core 1.33GHz SoC with Intel HD Graphics and the SoC has a six Watt TDP.

- An Intel Core i3 4130 as a low-end Haswell system. The Athlon 5350 is targeted more to compete with the Celerons and Atoms, but this was tested anyhow as an example of a slightly higher-end system. The Core i3 4130 is dual-core with Hyper Threading and clocked at 3.4GHz, sports Intel HD Graphics 4400, while having a 54 Watt TDP.

- AMD A10-7850K as some perspective of a Kaveri APU against the socketed Kabini. These APUs are in different leagues but it puts the performance into perspective for those interested. This 95 Watt APU is quad-core and clocked at 3.7GHz and sports Radeon R7 Graphics.

- An AMD E-350 board. The E-350 is dual-core, clocked at 1.60GHz, and sports Radeon HD 6310 Graphics. The E-350 has an 18 Watt TDP.

- An AMD E1-2100 Kabini via the ECS KBN-I motherboard. The AMD E1-2100 is a dual-core 1.0GHz APU with Radeon HD 8210 Graphics, and 9 Watt TDP.

All of this benchmarking was handled in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.

There were slight differences outside of the CPU/APU due to testing some other SoC boards that used mSATA disks, etc. Other tests, including performance-per-Watt / power consumption data, will be coming soon in other Phoronix articles.
