Xbox Series X vs PS5: Which Console Stays Coolest (2024)

Once everything was set, we used a Picoscope temperature logger to keep track of all temperatures. We also connected a GW-Instek power analyzer (GPM-8213) to check the power that the Xbox draws from the wall. At first, we used an HD monitor, but we decided later to go with a 4K one since most users will use high-resolution monitors.

Since we have Game Pass Ultimate, we downloaded several demanding games to stress the console’s hardware. But before referring to the operating temperatures, let’s check first average and peak power consumption in three games. We will also include PS5 power measurements to check which console is more power-hungry.

During our XSX test sessions, the ambient temperature was 22-23 degrees Celsius, while in the PS5 measurements, the ambient was 27.9 degrees Celsius.

Power Measurements

The most demanding game we tried on the XSX is Gears 5, while Forza Horizon 5 is less power-hungry, despite the fantastic graphics. Battlefield 2042 is a bit less demanding in energy than Gears 5. Finally, UHD gaming needs more power since it pushes the console more. For the PS5, we used Devil May Cry 5, which kept power consumption at high levels without any notable deviations.

The results are not 100% comparable since we are talking about different games, but we take the peak HD and UHD gaming readings we got after hours of testing to give you an idea of how much energy each console needs.

The Xbox is less demanding, consuming about 20W less in both HD and UHD gaming. We repeat, this has to do with the game, and we used the highest power consumption readings we got from both consoles in this graph.

Noise Measurements

We conducted the noise measurements using a Class 1 Bruel & Kjaer2270 G4Sound Analyzer, equipped with a type4955-Alow-noise and free-fieldmicrophone, measuring down to 5 dB(A). The sound analyzer was installed into a hemi-anechoic chamber, which allows for lower than 6 dB(A) ambient noise.

A Bruel & Kjaer Type4231was used before every noise measurement to calibrate the sound analyzer. Both consoles were installed one meter away from the mic, and we measured their noise during a 10 minute gaming period, at 25 degrees Celsius.

Neither of the two consoles is noisy, with the XSX being notably quieter. Its fan spins at very low speeds. Hence it is barely noticeable. You have to go close to it to hear it barely.

Some people complain about coil whine issues with the PS5's power supply. We didn't encounter any such issues during our tests.

Operating Temperatures

And the time has come, finally, to look at the operating temperatures. We will also include some PS5 measurements, but we should note that the temperature measurements between these two consoles are not fully comparable.

The hardware layout is different, so we cannot connect the temperature sensors at the same positions to have 100% comparable results. Nonetheless, you will get a feel for what is going on with each console's operating temperatures. Finally, we used a new revision, PS5, which despite its smaller heat sink, has about the same temperatures as the original PS5.

To measure the XSX's temperature, we used the same technique as in PS5. We ran some games until the operating temperatures reached a steady state, meaning no deviations after 5 minutes of logging. We also positioned the Xbox both upright and on its side to check the effect on its operating temperatures in the most demanding title.

We installed K-type thermocouples in various places inside both consoles to monitor operating temperatures, and we logged everything through calibrated Piscoscope TC-08 thermocouple data loggers.

Since Gears 5 requires more energy, it pushes the console more, so the APU reaches 74 degrees Celsius. The temperatures in the rest parts are relatively low, with the next hottest part being one of the VRM caps, which have a high tolerance for heat.

With the console installed on the side, the APU temperature drops slightly, while power consumption is higher. This means that the APU runs at higher speeds because of the more-efficient cooling.

The APU on the Xbox runs hotter, despite the lower power consumption and the lower ambient temperature during our tests, primarily because of the more relaxed fan speed profile and secondly because it uses plain thermal paste, while the PS5 uses a more exotic solution, liquid metal.

We cannot have a 100% fair comparison between the cooling systems of each console, but the outcome of these tests shows that both are highly capable of managing to keep operating temperatures low on all parts without requiring strong airflow, and this is what matters the most.

Conclusion

The Xbox Series X and the PS5 use a custom AMD Zen 2 SoC, with 8 cores and 16 threads. On the PS5, the maximum clock is 3.5 GHz, while the Xbox tops at 3.8 GHz. The Xbox Series X also has a more potent GPU with 52 Compute units, which run at lower speeds than the PS5's CUs, achieving more teraflops.

The Xbox seems to be more power-efficient; the PSU plays an important role here. Speaking of PSUs, the Xbox has a smaller unit that runs at 315W, while the PS5 uses a Delta-made PSU that can deliver up to 372W with 12V output.

In general, we measured lower power consumption on the Xbox, but someone could argue here that we should use the same games to verify this. Nonetheless, even if we used the same games, nothing could ensure that the code is equally optimized. In any case, this is why we ran several games on the XSX for power measurements, and we took the highest results, which we compared with the ones from the PS5.

The bottom line is that the Xbox Series X runs hotter on its SoC, but it makes notably less noise and it has smaller dimensions. The RAM runs cooler on the Xbox as well. Finally, in our tests, putting the Xbox on the side allowed for lower temperatures and power consumption increased, a sign that the APU was running at higher speeds.
