Dr. last August. Lisa Su introduces the world to the latest version of AMD’s CPU technology, Ryzen 7000-series– But it didn’t stop there. We have an announcement to make: RDNA 3, AMD’s next-generation GPU technology. Well today is November 3rd and now we know more about AMD’s response RTX 40. Series.

Dr. Sue began the presentation by reflecting on the release of the Ryzen 7000 series and presenting AMD’s ambitious goals, just as he did in previous presentations. For RDNA3, he reiterated the company’s commitment to energy efficiency and performance.

“We focus on performance and energy efficiency. We want to make sure we continue to innovate around mileage per watt to enable all player upgrades with great performance but reasonable performance.” – Dr. So is Lisa

Starting with the new chip design, RDNA 3 takes a modular approach with the goal of improving the overall efficiency of GPU designs. Similar to the Ryzen CPU family, the RDNA3 will use a hybrid chip architecture. Featuring a 5nm graphics die compute module (GCD) with all shaders, rendering drivers and an updated media engine, the GCD is combined with a 6nm memory cache die (MCD), which includes a GDDR6 controller plus 96 MB of AMD Infinity 2nd Gen. Infinity Cache Infinity Cache, that’s it!

With this new design, the RNDA 3 chip will have connection speeds of up to 5.3 TB/s (2.7 times faster than RDNA 2) and will be capable of processing power of up to 61 TFLOPS. All of these are powered by up to 24GB of GDDR6 with up to a 384-bit memory bus (not the GDDR6X we saw in the RTX 4090), and the Dr. Case in point, the RDNA 3 GPU will enable 54% more performance per watt than the previous generation.

So what is the secret of this magical GPU? Well, it’s actually two GPUs: Radeon RX 7900 XTX and RX 7900 XT.

Radeon RX 7900 XTX comes with 24 GB GDDR6 and Radeon RX 7900 XT comes with 20 GB GDDR6. Designed as 4K and 8K gaming graphics, the Radeon RX 7900 XTX and 7900 XT have a number of updates over previous generations that will bring them into the gaming future.

Starting with custom AI acceleration, RDNA 3 is said to improve GPU AI-based performance by 2.7x and ray tracing instructions by 1.8x compared to RDNA 2. For rendering applications – including ray tracing – this new architecture is expected to achieve up to 50% more performance per unit of account and double the number of instructions per hour. This is a much needed step forward for Radeon Graphics to compete in this niche area of ​​graphics processing!

But there’s more:

AMD’s new Radiance Display is the engine that brings all this data to the screen. The engine will support 12 bits per channel with up to 68 billion colors and higher refresh rates. Thanks to the larger introduction of DisplayPort 2.1 and HDMI 2.1, the RX 7900 XTX and RX 7900 XT support refresh rates of up to 900Hz at 1440p, 480Hz at 4K and 165Hz at 5K.

In addition to the Radiance Display Engine, AMD has also introduced a new dual-media engine for simultaneous encoding and decoding for AVC and HEVC formats. This engine supports AV1 encoding and decoding with a maximum resolution of 8K60 Later in the presentation, AMD revealed future support for AV1 encoder support in OBS as well as other popular video streaming and editing software. The teaser also features a futuristic feature called SmartAccess Video, which takes advantage of Ryzen CPUs and Radeon GPUs to provide up to 30% of 4K multi-stream encoding.

In terms of gaming performance, the RX 7900 XTX can perform up to 1.7x better than AMD’s previous flagship GPU, the Radeon RX 6950 XT, in rasterization and up to 1.6x better in ray tracing games. Using FidelityFX Super Resolution (FSR), the graphics shown by AMD for the 7900 XTX are running at frame rates over 200fps in 4K. He was one of the best braveWhich shows the RX 7900 running on the XTX 704 FPS! Lots of bold claims here, but we’ll have to see for ourselves when the cards are in the hands of third-party verifiers!

In terms of actual specs, the RX 7900 XTX will have 96 cores with a gaming clock of 2.3GHz. All this is said to work with a total energy consumption of 355 watts of panels. For comparison, that’s 95 watts less than NVIDIA’s RTX 4090 Founders Edition, while staying close to typical board power for the RX 6950 XT. The RX 7900 XT will have 84 cores with a game clock of 2GHz and a total board power of 300W.

Oh yeah, and won’t need a special cable to run.

However, this is only the device. AMD took some time to talk about the introduction of FSR, the performance improvements seen in FSR 2, and how well RDNA 3 works with it. An example given by the company was Ubisoft Assassin’s Creed: Valhalla It runs in 8K at 96 fps. It was a short clip but it’s crazy to see it all at once. But AMD wanted us to know that FSR doesn’t stop at FSR2. There is a new iteration, FSR3. At the time of the announcement, AMD said that Radeon users can expect double the frames per second on FSR2 and that the technology will be available in 2023.

Continuing the software conversation, AMD’s Frank Azor released Radeon Adrenaline software updates, including a new feature called AMD HYPR-RX coming in the first half of 2023. This feature will be a one-button optimizer that will give AMD systems the best possible performance without making all the adjustments.

Team Red also shared its commitment to delivering the best unified CPU and GPU experience by working with system integrators to bring the AMD Advantage line to desktop platforms. This means that AMD GPUs and CPUs are added to system configurations that are carefully tuned by AMD to deliver the best possible AMD experience.

Radeon RX 7900 XTX and Radeon RX 7900 XT will be available on December 13, 2022. How is the price? $999 and $899 respectively. That’s a surprising difference from NVIDIA’s $1,599 flagship.

We look forward to seeing these GPUs in the wild! Let us know in the comments what AMD announcements you’re most excited about today and if you plan to upgrade before the end of the year.
