If you want to make a
statement with the best gaming card money can buy, look no further than
the new ROG Strix GeForce RTX 4090. With unprecedented power, this card
is designed for ultra-high resolutions or super-fast refresh rates that
help you reign supreme on the battlefield.
In order to extract the ultimate performance from the Strix GeForce RTX
4090, we built it with cooling as our top priority. The cards 3.5-slot
design consists of a die-cast metal frame, shroud, and backplate. The
ultra-rigid structure uses frames with extremely tight tolerances to
prevent the PCB from sagging or warping, while still allowing for
unparalleled airflow through an enlarged pass-through vent along the
back of the 357mm long card.
But with an ultra-powerful GPU like the GeForce RTX 4090, we wanted to
go further than a large heatsink and vented backplate. So we rebuilt the
heatsink design from the ground up, with a new vapor chamber and 30%
more surface area for heat dissipation than the previous generation ROG
Strix GeForce RTX 3090.
This is no ordinary vapor chamber, however. In order to provide better
heat transfer, this patented vapor chamber design adds milled channels
underneath the heatpipes. Instead of the pipes lying flat against the
surface, they sink into the vapor chamber, allowing more heat to
efficiently transfer to the four 8mm and three 6mm heatpipes and travel
to the heatsink fins. When subjected to a 500W thermal load, this potent
pairing allows for 5°C cooler temperatures than a conventional vapor
We also upgraded the Axial-tech fans, with a thicker design featuring 7
blades and full barrier rings that provide 23.8% more airflow and 19.3%
more pressure than the previous generation fans used on the ROG Strix
GeForce RTX 3090. With these improvements, we were able to keep GPU
temperatures and acoustics at similar levels to the previous generation
model, despite the extra power.
Speaking of power: this is an absolute monster of a gaming card, so
weve included a 12+4 phase system comprising 70A power stages. With two
power stages per phase fueling the GPU, thats a total count of 24+4.
The digital controller on board offers higher precision when detecting
power, as well as better power conversion and balancing for less noise
and signal interference. With a quality power supply in place (like our
ROG Thor 1200P2), you should have no problem driving this beast of a
graphics card, and with native 16-pin PCIe support, you can do it
without any adapters required.
All of this comes with the same high-end features ROG Strix cards are
known for. An ARGB tail-light works with Aura Sync to offer customized
lighting across your build, while two FanConnect II headers allow you to
control your case fans with your GPU temperature through our new GPU
Tweak III software. For those who dont want to dig in and tweak too
much, the Dual BIOS switch allows you to choose between maximum
performance mode and a quieter mode. Though thanks to our 0dB
technology, the card will be silent at low loads no matter which mode
Finally, like our other ROG cards, the Strix GeForce RTX 4090 was built
with our Auto-Extreme manufacturing process that minimizes human
intervention, so you can expect reliable long-term performance right out
of the box.
