Sapphire Radeon RX 5700 XT Pulse Review - Navi with certain vibrations | Page 7

Sapphire's first Navi card is with the Pulse actually the entry model, if one follows the previous nomenclature of the manufacturer. This also entails compromises and today we will sound out which and what this means for the customer.

Temperature curves and boost clock rate in detail

The cooler works well for its size and since I want to compare the two BIOS versions, I completely dispense with the values of the open benchtable, which is unrealistic anyway. The comparison reveals a greater difference in both clock rate and temperature. The OC-BIOS allows temperatures from 71 to 70 °C, while the Silent BIOS exceeds this mark with approx. 74 °C. The OC-BIOS is a very good choice for the Silent BIOS. Interestingly, the extreme jumps in the clock rate hardly have a negative effect on the percentiles, so that the Silent BIOS is actually the more sensible solution here as well. In spite of all the regulatory frenzy.

This doesn’t look any different in the stress test, as the waste heat is largely the same as the power consumption.

And now the whole thing again in sober numbers in table form, whereby I compare both BIOS versions in the closed case:

	Initial Values OC and Silent BIOS	Final Values OC BIOS	Final Values Silent BIOS
GPU Temperatures	33 °C	71-72 °C	74 °C
GPU Clock Rate	1925 MHz	1837 – 1925 MHz	1734 – 1783 MHz
Room Temperature	22 °C	22 °C	22 °C
Air Temperature in the Case	25 °C	44 °C	42 °C

Board Analysis: Infrared Images

The following picture gallery shows all infrared images for the gaming and torture loop in a closed case, but with both BIOS versions as comparison. The pictures are self-explanatory and speak a clear language. And I would like to point out once again that the sensor values for the memory are absolute nonsense, as the temperature under the flip-chip modules of the memory is also measurably lower on the board side
