AMD took the wraps off of its latest Radeon RX 7000 family of graphics cards at its Together we advance_gaming event in Las Vegas, Nevada. The Radeon RX 7000 series of GPUs will succeed the current Radeon RX 6000 family and rely on AMD’s new RDNA 3 graphics cores as the company takes on rival Nvidia’s recently unveiled GeForce RTX 4000 series of GPUs.
“At AMD, we’re all about high performance and adaptive computing,” CEO Lisa Su said during her company’s keynote, noting that AMD is in the midst of introducing four new architectures across multiple product lines.
Su said that gaming is in AMD’s DNA in unveiling the RDNA 3 architecture.
“Our mission is to bring you the best experience possible,” Su said. In addition to powering AMD’s PC graphics cards, the company’s GPU cores are also found on consoles, workstations, and smart automotive.
“Today, it’s all about the next generation of graphics,” Su said. With RDNA 3, AMD set ambitious goals with power and efficiency. AMD is pushing its performance-per-watt leadership with RDNA 3 to support 4K gaming and beyond. “There’s a lot of innovation in RDNA 3 and we’re going to tell you all about it today.”
With RDNA 3, AMD is using a modular approach with a chiplet design, mixing and matching the right technology for each function. There’s a 5nm graphics compute die and a 6nm memory cache die, which includes the memory subsystem and 96MB of Infinity Cache. “As a result, we have incredible capabilities with 61 teraflops of compute,” Su said, noting that the company has the fastest chiplet interconnect.
“We have 58 billion transistors in this design,” she said.
Su claimed that AMD had exceeded its goal with energy efficiency, reaching more than 54% gen-over-gen performance-per-watt with RDNA 3.
The company unveiled its flagship RX 7900 XTX graphics card with its RDNA 3 architecture at the event.
“With RDNA 3, our vision is to engineer the most advanced 4K and 8K platform, AMD said. “To achieve this vision, we have brought unprecedented innovation.”
These innovations include the chiplet design to GPUs, which AMD had honed in on its CPU products. There are two different chiplets that are connected together.
The tuned Infinity Cache, according to AMD, is 2.7x faster than the RDNA 2 design.
On the graphics compute die, it’s built using the new RDNA 3 core, which comes with new display engine and dual media engine.
Improvements include better A.I. processing and better ray-traying performance. A.I. performance has been improved up to 2.7x, AMD said. With ray-tracing, there’s up to 50% more performance per compute unit.
The new Radiance Display Engine supports DisplayPort 2.1, a first for a high performance graphics card, the company said. It supports 8K 165Hz or 4K 480Hz.
The dual media engine supports two media or encode stream. The performance has been improved by 1.8x, reducing the export time by almost one-half.
AMD Radeon RX 7900 XTX
AMD claimed that it has been working on this new graphics card for three years. The flagship RX 7900 XTX is up to 1.7x faster than the company’s prior flagship.
This new GPU comes with 96 compute units and is clocked at 2.3GHz. It comes with 24GB of GDDR6 memory. It’s future-ready, AMD said. The card uses 355W of total board power.
In addition to the RX 7900 XTX, AMD also introduced the RX 7900 XT. Taking a jab at rival Nvidia, AMD said there’s no need to get a new case or power adapter. It’s all just plug-and-play.
