Data gathered from this array of sensors is used to determine what AMD is calling the "Junction Temperature", and it's the Junction Temperature data that is used to tune the cards' power and thermal profiles (the Junction Temperature is effectively the hottest part of the GPU die at any given time). With newer GPUs, AMD has incorporated a network of multiple thermal sensors at strategic locations across the die. In previous-generation Radeons, though the GPUs had multiple sensors built-in, a single sensor had been used to determine the GPU temperature and data from that lone sensor was used to control the card's thermal profile. Radeon RX 5500 XT Default Setting Hardware Health Data With the tuning options built into AMD's driver suite though, users have the ability to manually alter frequencies, voltages, fan speeds and the power target, to fine tune performance, power, and acoustics. Like previous-gen Radeons, when the Navi-based GPU at the heart of this card is boosting, frequencies and voltages scale upwards (power and temperature permitting) based on the GPU's workload at the time. We also spent some time overclocking the 8GB Radeon RX 5500 XT using the performance and tuning tools built into AMD's Adrenaline Edition 2020 drivers, which were just recently released.
As you can see, the 4GB Radeon RX 5500 XT trails its 8GB counterpart by about 40%. Even still, this is what could happen more often as games get more graphically complex and consume more than 4GB of video memory moving forward. This game clearly favor's NVIDIA's architecture, and we're running at a very high resolution. We are presenting these FF XV benchmark scores to clearly illustrate the potential pitfalls of having only 4GB of memory on a graphics card as we head into 2020.
