Currently, the RTX 4090 video card is the best of all models on the consumer market, but Galax, a Chinese manufacturer with a very impressive arsenal of good solutions, decided in honor of its 20th anniversary to make it even more attractive to potential buyers. To do this, the manufacturer presented the Galax GeForce RTX 4090 20th Anniversary Edition video card, which is equipped with a special HDMI signal retimer, which no consumer model on the market currently has. The company released the first graphics accelerator with this chip, creating an interesting move for future marketing campaigns.
An HDMI signal retimer is a small integrated circuit that is soldered onto the printed circuit board of a video card and allows you to improve HDMI signal transmission over long distances via cable. It is worth noting that this kind of development costs nothing and is actively integrated into game consoles like PlayStation 5 or Xbox Series X|S, as well as in laptops and more.
This is necessary so that a gamer who connects his console or laptop to a TV from a long distance using an HDMI cable receives the highest quality signal without artifacts, glare and other troubles.
No one had previously used these types of components in video cards, because the video card is most often located two or three meters from the monitor or TV, so manufacturers simply did not see the need for this. Galax decided it was time to change that, so they added a Parade PS8419 retimer chip to the PCB of their RTX 4090, which improves the signal purity of the HDMI 2.1 port at a data transfer rate of 12 Gbps.
The company explained that the chip makes it possible to level out temporary distortions in data transmission channels and synchronize signal transmission from the source to the monitor. As a result, the user can connect the video card to a TV in the next room via an HDMI cable and receive a high-quality signal.
In addition, the manufacturer has implemented an unusual cooling system in the Galax GeForce RTX 4090 20th Anniversary Edition – there are three fans installed, but one of them is located on the back side and it blows through the radiator grille. Typically, manufacturers use two or three fans that blow through the radiator from below, but in this case, through blowing is implemented, which, theoretically, should improve the temperature regime of the model. True, you will have to pay a lot for the video card, because they plan to release it in a limited edition, and in general the RTX 4090 is extremely expensive.
