Overclocking and Test Setup

Overclocking

Overclocking AMD's Athlon processors is simple, largely because there aren't many configurable options. Our motherboards don't support BCLK adjustments with these CPUs installed, leaving the ratio multiplier as our only knob for tuning clock rate. We're also unable to boost memory performance above the stock DDR4-2666, though we did adjust timings to 14-14-14-34.

Integrated graphics overclocking isn't an option either. Try as we might, the Vega 3 engine remains locked at 1 GHz.

As we've seen from many of AMD's chips, the Athlon series tends to have an overclocking frequency ceiling imposed by the limits of GlobalFoundries' 14nm process. Even with prodigious amounts of voltage, we weren't able to break through the 3.9 GHz barrier with any Athlon model. However, we were able to achieve a rock-solid 3.9 GHz on all three processors using the stock thermal solution, and overclocked performance results for all of them landed within the run-to-run variance we expect in our benchmark suite.

To avoid unnecessary clutter in our charts, we're presenting the results of the Athlon 240GE at 3.9 GHz. Expect similar performance from the other two models after tuning. 

From the default 3.5 GHz, we achieved a stable 3.9 GHz in an AVX-optimized stress test using a 1.4V Vcore and 1.15V SoC voltage setting. Temperatures with the stock cooler never exceeded 78°C at 3.9 GHz. For the sake of comparison, running the same test with a Corsair H115i on top of our Athlon 200GE yielded a 45°C reading. Power consumption for the overclocked CPU+SoC topped out at 51W.

We paired our Pentium Gold processors with a Z370-based motherboard, which does support faster memory. Sticking with Intel's official specification, we used our modules at 2400 MT/s to represent the data rates available from B- and H-series platforms.
