Of course, according to the Radeon Display Engine specifications on the 'Navi' GPU family, the HDMI port at 5600XT will support the HDMI 2.0b standard, and DisplayPort 1.4 / 1.4a with Display Stream Compression support for high resolution displays above 4K.
Then also of course there is support for variable refresh-rate like Radeon Freesync.
Sapphire Pulse RX 5600XT has a Dual BIOS switch, which they use to make this card run in Performance Mode, or Quiet Mode. (For overclockers, you can also choose to flash another BIOS and use one of these BIOS for experiments, for example)
It should be noted that as we said on the previous page, we will be testing with 160W Performance Mode (in accordance with Sapphire retail specifications), and also a 150W pre-release BIOS version that complies with AMD specifications.
Temperature measurements are 'traditional' generally done by reading a sensor placed on a chip / package, and sometimes the temperature reading can depend on the position of this sensor. If the sensor is located some distance from the heat area of the chip, it is possible to see temperatures that are lower than they should (for example: the sensor on the edge of the chip can read the temperature of 80C, but the hottest temperature in the middle of the original chip has reached 100C or more ).
When testing, generally chip manufacturers will calibrate their chip temperature readings to set the maximum permissible temperature, before the chip experiences thermal throttling. Since using 7nm fabrication, AMD displays this hottest temperature value as 'Hot Spot' or 'Junction Temperature'.
On modern GPUs that generally change clockspeed and voltage dynamically based on various things including temperature, AMD claims that with more precise temperature readings through the 'Hot Spot' it allows them to apply more aggressive clockspeed / voltage rules, 'squeeze' all capabilities of the GPU they have to be operated at the maximum thermal limit, while still maintaining the reliability of the GPU in accordance with the limits set by AMD.
By default, Sapphire Pulse operates their fans at a small RPM (under 1300 RPM), to keep the noise level low, this also seems to be sufficient to maintain a reasonable temperature.
When we make a fan fixed to 39% in Radeon Software Tuning, or around 1700 RPM, GPU temperatures can drop dramatically. Even in the overclocked condition, this 1700 RPM fan can keep the GPU temperature at 71 C. This 1700 RPM fan is still relatively quiet for daily operations.
Power & Power Efficiency
Overall power consumption is good in its class, slightly lower than RTX 2060 for similar performance, and in Game SOTTR at 1080p, FPS per Watt of RX 5600 XT is superior to RTX 2060
Surprisingly, overclocking with the setting of 1820Mhz @ 1006 mV does not shift the power efficiency, meaning that the performance provided is in line with the increased power consumption.
