When it came to overclocking, our 1600X sample was good for 4.1GHz while the 1500X sample hit 3.95GHz. Testing with Premiere Pro saw the 1600X boost its performance by 9% once overclocked, making it slightly faster than the stock Core i7-7700K and not much slower than the stock 1800X.
The 1500X performance was improved by just 4%, which was disappointing, mostly because overclocking the 7600K lead to an 18% improvement taking just 267 seconds. That said, the 7600K is a more expensive processor and requires a third party cooler as well. Compared to the similarly priced Core i5-7500, the overclocked 1500X was 28% faster, so that's great news for AMD.
The overclocked 1600X managed to draw a few more frames in Battlefield 1, though the result wasn't worth getting excited over. The overclocked 1500X was a little more impressive as it landed just ahead of Intel's Core i5-7500.
Here the 1600X gained 6% more performance in Ashes of the Singularity once overclocked, allowing it to beat the overclocked 7600K, at least when comparing the average frame rate. The overclocked 1500X was 14% faster than the 7500, hitting a solid average of 73fps.
