The Ryzen 5 Review: 1600X and 1500X Take on Core i5
Memory Speed Scaling and Windows 10 Power Modes
AMD has been pushing the use of higher speed memory with the Ryzen 5 reviews in order to compensate for some of the performance impact and deltas seen in the Ryzen 7 reviews. I have already noted the potential conflict in regard to cost, but how does increased memory speed improve an array of our testing applications?
Memory speed improvements are negligible from 2400 MHz to 3200 MHz in Cinebench single thread and multi-thread iterations, Handbrake H.264 encoding, Blender rendering, and one game, Ghost Recon: Wildlands. Geekbench shows reasonable performance increases in both single threaded and multi-threaded results, indicating that some workloads (compression, speech recognition) can still improve with faster fabric/memory.
The gaming results show 12-14% jumps when running at 3200 MHz compared to 2133 MHz. That is clearly a big enough gap to warrant the purchase of 3200 MHz memory and to push the adoption of those higher speeds for general usage. Intel’s architecture doesn’t require higher speed memory and sees very little uptick from the higher speed, higher cost memory.
Windows 10 Power Mode Testing
I did a considerable amount of testing to compare the Balanced and High Performance modes in Windows 10 with Ryzen 5, in this case we are showing results from the 1500X. There were only three data points of interest – WebXPRT (+14%), Cinebench ST (+4.7%) and Rise of the Tomb Raider (+3.6%). In all other instances the difference between the two settings was well within the margin of error and I would view the positive results as the outliers. The WebXPRT result is the MOST interesting to me as it is indicative of an inherent advantage in responsiveness without the core parking concerns of the Windows 10 Balanced profile.
