As promised and CEO Lisa Su leading the keynote, AMD presented the next generation of its GPU family Radeonunder the RDNA 3 architecture in which they will answer Lovelace Architecture by Nvidia.
Lisa Su claimed that at AMD they are proud to not only be going as scheduled but already overtaking their initial goals as RDNA 3 surpassed RDNA 2 with a 54% more efficiency and RDNA 3 was called the first “chiplet”, a new way of describing hefty package in a chip.
The RDNA 3 or the first gaming chiplet, features 61 Tflops of compute, 5.3 TB/s, and 58 billion transistors in a 5 nm manufacturing which brings more power usage efficiently along with better capacity.
It is called chiplet because the architecture is a modular assembly of components that talk to each other instead of a simple traditional chip with all components embedded one to another and while it was manufactured in 5nm.
So this is a great jab for Intel, Samunsg, Nvidia, ARM, TSMC and Qualcomm as everybody has studied the concept but haven’t implemented it yet.
As expected the main representative for the family will be the Radeon 7900XT for massive 4K needs and professional usage possible and also a new entrant called the Radeon 7900XTX and as the name implies, this will be more "entry level" (in their category) between the two.
Both GPUs of the Radeon 7900 family will have support for DisplayPort 2.1 with the capacity of giving high rate support for both 4K and 8K resolutions, encode and decode AV1 and for 8K resolutions, refresh rate can get to 165Hz of frequency.
The Radeon 7900XT includes 20GB of VRAM DDR6, 84 CUDA Cores, 2GHz and respectively the Radeon 7900XTX goes with 24GB of VRAM DDR6, 2.3GHz and just consumes 335W.
The goodies of both of them, they don’t look like beefy monsters and DOES NOT REQUIRES SPECIAL PIN CONNECTOR, an instant win for AMD.
Software drivers improvement includes DirectX Ray which will debut on Season of Halo Infinite and Super FidelityFX Resolution 2, which will duplicate ALL the performance of original SFR in terms of AI anticipating image sample for further fps improvement.
Finally, AMD HYPR-RX mode combines AMD's software features to provide a simple, one-click experience so you can just sit down and get in the game by adding extra frame rates and reducing latency in a smart way, making hardware bump up.
With this the 4K consumer variant Radeon 7800XT and 1440p friendly Radeon 7700XT are still pending to be announced and launched.
Both Super FidelityFX Resolution 2 and AMD HYPR-RX mode will be coming via driver update in 2023.
Returning to AV1 and this is for content creators, RDNA 3 will include the RDNA 3 Media and AMD said that the RDNA 3 Media engine can have up to 7x speed improvements of its predecessor, including the SmartAccess.
SmartAccess will share the encoding and decoding workloads of content to Ryzen CPU and Radeon GPU, pretty much like the concept of in-gaming performance in RNDA 2 and in simple words, will make your video editor complete a video in less time with the final product on high quality.
Both the Radeon 7900XTX and the 7900XT will be released on December 13th costing respectively $899 and $999 in most suggested retail price and also we can expect OEM variants and individual pricing will vary depending on added spec by each individual manufacturer.
