AMD's first RDNA3 GPUs are the Radeon RX 7900 XTX and 7900 XT
, all eyes are on AMD to see how it will respond. Today, the company announced the Radeon RX 7900 XTX and RX 7900 XT, two confusingly named GPUs powered by its new RDNA 3 architecture. On stage during its Las Vegas launch event, AMD CEO Dr. Lisa Su claimed the new hardware offers a 54 percent increase in performance per watt over the previous GPUs.
These cards aren't just a mere spec bump. Su says RDNA 3 is the world's first chiplet-based GPU, giving it a modular design that can be easily tweaked down the line. Currently, those chiplets include a 5nm GPU compute die and a 6nm memory cache die. It's capable of reaching up to 61 teraflops of computing power , can manage up to 24GB of GDDR6 RAM and consists of 58 billion transistors.
Naturally, the flagship Radeon RX 7900 XTX gets the full 24GB of RAM, while the 7900 XT will ship with 20GB. Both cards look similar to AMD's last-gen hardware, albeit with bigger fans and a sleeker heatsink design. AMD SVP Sam Naffziger also joked that you won't need any new power cables for these cards — you should be able to drop them into your existing system.
