Overclocking The AMD AM1 Athlon & Sempron APUs
With the C-Ray multi-threaded ray-tracer there's noticeable performance improvements with the slightly overclocked APUs, but nothing too dramatic.
For those intending to use AMD AM1 boxes with Linux for more than just a simple file server / NAS or network gateway, overclocking these APUs with the ASUS AM1I-A motherboard can squeeze the maximum potential out of these ~$50 APUs.
The Athlon 5350 was about 7% faster with OpenSSL with its light overclocking, which is similar to the 5~8% gains out of the other AM1 APUs.
Check out yesterday's four-way APU comparison for more open-source Linux benchmarks on this budget-priced hardware. On a related note to the overclocking is also the AM1 DDR3 memory speed testing I did last week. Many other interesting tests looking at various aspects of AMD's 2014 AM1 Platform are forthcoming on Phoronix in the days ahead. Like all of these tests of the new AMD hardware? Join Phoronix Premium today to allow the extensive Linux hardware testing to continue. Coming up tomorrow will likely be the RadeonSI Gallium3D vs. Catalyst Linux OpenGL benchmarks for all four of these APUs.
