AMD Ryzen 7 5700X3D Review: A Value Gaming Masterpiece

AMD Ryzen 7 5700X3D Power Consumption and Efficiency 

Image 1 of 7

The Ryzen 7 5700X3D consumes a peak of 117W, an impressive 100W less than the Core i5-14600K that it actually beats in gaming workloads (but trails in productivity applications). Notably, this is much lower than the theoretical PPT (peak) of 141W for AMD's 105W TDP rating. As expected, the Ryzen 7 5800X3D with higher clock rates pulls a few watts more during most workloads, highlighting that there isn't much difference between the two chips in day-to-day workloads. 

The Zen 3 Ryzen 7 5700X3D trails the 5800X3D slightly in the renders-per-watt power efficiency metric. Intel's previous-gen Core i5-13400 is the most efficient chip in our test pool, but the current-gen Core i5-14400 trails the Ryzen models, a victim of Intel's tactic of pushing power consumption higher for slim performance gains. 

The Zen 4-powered Ryzen 5 7600X consumes more power than the Ryzen X3D and Core i5 models, roughly  ~10% more power than the Core i5-14400, but it delivers higher performance in many of these workloads. That results in a minor difference in efficiency compared to the Core i5 but a more pronounced difference compared to the X3D chips.

The final image takes a slightly different look at power consumption by calculating the cumulative energy required to execute an x264 and x265 HandBrake workload. We plot this 'task energy' value in Kilojoules on the left side of the chart.

These workloads consist of a fixed amount of work, so we can plot the task energy against the time required to finish the job (bottom axis), thus generating a really useful power chart. Faster compute times and lower task energy requirements are ideal. That means processors that fall the closest to the bottom left corner of the chart are the best.

AMD Ryzen 7 5700X3D Overclocking, and Test Setup

The Ryzen 5 5600X3D doesn't support overclocking via the CPU multiplier, so you can't change the core clocks directly. You also cannot alter the power limits (PPT, TDC, EDC) or CPU voltage. The chip also doesn't officially support the auto-overclocking Precision Boost Overdrive (PBO) feature, and you can't undervolt or underclock.

We tested the Ryzen 7 5700X3D in standard stock trim and then experimented with engaging the Precision Boost Overdrive (PBO) feature. MSI's motherboard did deliver at least some single-digit percentage gains in gaming performance with PBO enabled. MSI also has more rigorous overclocking mechanisms for X3D chips, but given that AMD doesn't officially support any direct CPU core or voltage overclocking for the X3D chips, this is exceptionally risky. Proceed at your own risk. 

The 5600X3D supports overclocking the memory and Infinity Fabric, but we could only reach DDR4-3600 with the fabric at 1800 MHz (low-latency 'coupled' mode - 1:1 ratio). You can get higher transfer rates with uncoupled memory, but that results in less performance in games. Combined with the PBO option, DDR4-3600 also gave us a slight gaming performance increase. However, memory tuning is of less benefit than with standard Ryzen chips — it's clear that the extra L3 cache does the heavy lifting.

As usual, we followed our policy of allowing the motherboard to exceed Intel's recommended power limits as long as the chip remains within warrantied operating conditions. Almost all enthusiast-class motherboards have similar default settings, reflecting the out-of-the-box experience. These lifted power limits equate to more power consumption and heat, but you get faster performance in exchange. Intel has encountered issues with its Core i9 chips and the higher power limits, but we haven't heard reports of those settings impacting performance in any of the lower-tier Core i5 models. 

As noted in the charts, we used the DDR5-6400 EXPO profile for the overclocked Ryzen 5 7600X configuration. We also used Precision Boost Overdrive (PBO) with the 'motherboard' power presets for our overclocked Ryzen 5 7600X configuration. We then enabled a 10X scalar, a 200 MHz extra boost for the CPU, and a -20 undervolt using the Curve Optimizer for the CPU cores.

Microsoft has advised gamers to turn off several security features to boost gaming performance. For maximum performance, we disabled secure boot, virtualization support, and fTPM/PTT on all systems. The table below provides further hardware details.
