Now that NVIDIA has kicked off the latest online video card wave with the insanely highly effective RTX 4090, all eyes are on AMD to see how it will react. These days, the corporation announced the Radeon RX 7900 XTX and RX 7900 XT, two confusingly named GPUs driven by its new RDNA 3 architecture. On phase during its Las Vegas start celebration, AMD CEO Dr. Lisa Su claimed the new components presents a 54 p.c maximize in effectiveness per watt in excess of the past GPUs. She also emphasized that AMD is targeted on providing intricate general performance with fair ability usage, a very clear knock towards NVIDIA’s electrical power-hungry (and PSU cable-melting) RTX 4090.

And, as is typical for AMD, it can be also hoping to undercut its principal competitor in pricing. The Radeon RX 7900 XTX will sell for $999, when the RX 7900 XT will go for $899. Both of those cards will start on December 13th. That’s far additional fair than the $1,599 RTX 4090 and $1,199 RTX 4080. 

These playing cards aren’t just a mere spec bump. Su claims RDNA 3 is the world’s to start with chiplet-centered GPU, offering it a modular design and style that can be conveniently tweaked down the line. Currently, these chiplets include things like a 5nm GPU compute die and a 6nm memory cache die. It really is able of achieving up to 61 teraflops of computing electricity (up from a maximum of 23 TFLOPs in RDNA 2), can deal with up to 24GB of GDDR6 RAM and consists of 58 billion transistors.

By natural means, the flagship Radeon RX 7900 XTX gets the entire 24GB of RAM, although the 7900 XT will ship with 20GB. Both playing cards appear very similar to AMD’s past-gen hardware, albeit with even larger enthusiasts and a sleeker heatsink design. AMD SVP Sam Naffziger also joked that you would not need any new energy cables for these cards — you need to be in a position to fall them into your current procedure. 

When it comes to ray tracing, historically a person of AMD’s weakpoints, the corporation claims the new cards have a upcoming-era accelerator with 50 per cent additional performance for every compute device. They are going to offer 1.5 moments much more rays in flight, new focused instruction and upgraded ray box sorting. Ideally, that indicates we’ll see closer ray tracing parity with NVIDIA’s playing cards. The Radeon 7000 GPUs also function AMD’s new Radiance Display Motor, with support for 480Hz 4K gaming and 165Hz 8K effectiveness. (And certainly, the latter appears like a extend to us, as well.)

So what do these cards search like on paper? In addition to its large 24GB of GDDR6 RAM, the RX 7900 XTX features 96 compute units working at up to 2.3GHz, all with a 355-watt electrical power draw. The 7900 XT, in the meantime, sports activities 84 CUs, a 2GHz clock speed and a 300 watt power attract, together with its 20GB of GDDR6 memory. AMD has also partnered with organizations like Samsung for DisplayPort 2.1 watch, which really should arrive early following calendar year. Amazingly, Samsung made available up a juicy tidbit: Its new Odyssey Neo G9 monitor will supply an 8K ultrawide resolution. (The far better query is should any one be aiming for 8K gaming at all.)

As for gaming effectiveness, AMD says the RX 7900 XTX attained up to 295fps though participating in Apex Legends in 4K, and up to 704fps in Valorant. Given that the refresh price restrict of DisplayPort 1.4 is 240Hz, which is a whole lot of functionality today’s displays won’t even sign-up. AMD also statements its GPUs are viewing up to 96fps in Assassin’s Creed Valhalla with Fidelity Fx Super Resolution (FSR). 

Notably missing, of system, is any comparison to NVIDIA’s RTX 4090. Probably AMD just didn’t have time to benchmark that card, but it will be attention-grabbing to see just how competitive the RDNA 3 GPUs will be.
