Its been a while since the launch of the Radeon RX 7900XTX/XT from AMD and today we’ll be looking at the offering from PowerColor, the Radeon RX 7900 XTX Hellhound. For those unfamiliar with the RDNA3 architecture, its the next-generation GPU architecture froim AMD released in Q4 2022 and debuts with the flagship two models: the Radeon RX 7900 XTX and the Radeon RX 7900 XT. It has been a few months now and AMD has not released any new cards with RDNA 3 despite the architecture featuring the first chiplet design on GPU which solves a few things, one of them is optimal utilization of their node.
RDNA3’s chiplet design allows AMD to move components that don’t require bleeding edge to still be fabbed on older nodes hence RDNA3 will feature a mix of 5nm and 6nm modules on the die. Alongside this, AMD also improved performance on RDNA3 to provide a leap around 50% much like RDNA2 from its predecessor.
In this review we’re taking a look at the top-end Radeon RX 7900 XTX as desingned by PowerColor. The company has multiple variants of the RX 7900 series starting with the Hellhound, the Red Devil and the Liquid Devil. The Hellhound is the starter model from the PowerColor’s offering but features much of the essentails that make up their entire product stack.
The PowerColor Radeon RX 7900 XTX Hellhound’s most distinct feature is its bi-color fans. While it doesn’t feature RGB, the frozen blue and grim purple do jive with the Hellhounds’s theme. The fan themselves are dynamic and temperature controlled with the PowerColor setting a 60*C target from idle for the fans to ramp up while it targets 50*C before the fans ramp down from load. This in turn cools the new large cooler. This cools the Navi 31 GPU as well as the 12+3+2 VRM on the Hellhound.
AMD decided to go with the currently-used PCIe power connectors unlike NVIDIA who went with the new ATX 12VHPWR. You will need two 8-pin PCIe power connectors for the Radeon 7900 XTX. The 7900XTX is rated for 350W and the 7900 XT at only 315W.
In this review we’ll talk about performance of the PowerColor Radeon RX 7900 XTX Hellhound.

Hopefully the Sapphire Pulse gets tackled too. Been eyeing it since it’s small enough to fit in my case
Miguel Araneta planning to get buy the Nitro+ personally but the Pulse looks clean din, planning to watercool it too so might just get the xtx pulse

Back2Gaming according to reddit same board lang daw yung Pulse and Nitro+ pero no dual bios sa Pulse
