Radeon RX 5700 XT – Printed circuit board
The power part of the Radeon RX 5700 XT GAMING OC circuit board in general follows the reference VRM. GIGABYTE uses a seven-phase voltage regulator to power the GPU core running the well-known Rectifier IR 35217 PWM controller, while the GDDR6 chips serve two keys and the ON Semiconductor NCP81022 chip. However, further differences can be found.
For example, the designers of the reference boards were clearly not concerned with the economically feasible choice of components: the voltage regulator is excessively powerful, and even AMD did not spare integrated chips with a rated current of 70 A to power the RAM. Each developer of mass products should expect that VRM will be in one way or another degree truncated. So, instead of 70-amp keys, GIGABYTE opted for power stages SiC620A manufactured by Vishay Siliconix, designed for 60 A, although in this case, the current margin for the Radeon RX 5700 XT caliber graphics card is still huge.
The main advantage of high-quality components is their efficiency, because the keys of the voltage regulator, RAM chips and the graphic processor Radeon RX 5700 XT GAMING OC live under a common radiator. Through-hole electrolytic capacitors as part of all voltage regulators that are on the board – this is another sign of the inevitable and justifiable savings on the cost of the accelerator.
GDDR6 RAM is equipped with Micron chips with a standard bandwidth of 14 Gb / s per contact. In the past, they demonstrated higher frequency potential compared to similar Samsung chips, which also fall into the Radeon RX 5700 and RX 5700 XT, but whatever the overclocking result this time, we note that the GDDR6 chips are interchangeable, and the manufacturer of the video card may Switch between Micron and Samsung, even within the same model.
To output the image to the monitor, the Radeon RX 5700 XT GAMING OC has three DisplayPort connectors and a single HDMI.
