Gainward RTX 2080 Phantom GLH in review – Reason card behind bars | igorsLAB

Gainward (i.e. The gaming brand of Palit) relies on a complete self-design for the board and a 2.5-slot radiator structure with three 8.5 cm fans (opening 9 cm, 15 rotor blades) in the Phantom GLH ("Goes Like Hell") that build up a correspondingly static pressure. The longitudinal, chrome-plated pipes are visually an eye-catcher, but do not influence the air flow measurement or audible. But more on that later. The card is also one of the few cards on the market with a true dual BIOS.

The 1382 g card is on average 29.3 cm long, measures 12 cm from top edge slot panel to top edge graphic card case and is 5 cm thick. In addition, there is another 0.5 cm for the blackened backplate. This means that it can already encounter space problems if housings are too small. The cover is made of plastic in the base with attached, black light metal applications in Buish optics and two silver longitudinal temples.

In addition, there are also optical accents such as the illuminated strips with RGB lighting embedded at the top, which can be controlled by driver and can also be switched off. The GeForce logo on the top is only embossed.

Gainward delivers the card with two external 8-pin ATX power supply connectors. The BIOS 1 delivers slightly more boost clock (1875 MHz to 1800 MHz), but leaves the fans in the idle at approx. 800 rpm lightly sour, while BIOS 2 allows a little less boost, but offers a fan stop. Why it was decided. But even more on that later. The screenshot of GPU-Z gives us a first impression:

Test system and measurement methods

We have already described the new test system and the methodology in detail in the basic article "How We Test Graphics Cards, as of February 2017" and therefore refer to this detailed basis for simplicity. Description. So if you want to read everything again, you are welcome to do so. However, we have again improved CPU and cooling to largely exclude possible CPU bottlenecks for this fast card.

If you are interested, the summary in table form quickly provides a brief overview:
