AMD’s RDNA 3 GPUs are Way Cheaper Than the RTX 4090

Back in August , Dr. Lisa Su introduced the world to AMD ’s newest iteration of CPU technology , the Ryzen 7000 Series – but she did n’t stop there . We got an declaration for an announcement : RDNA 3 , AMD ’s next generation of GPU technology . Well , today is November 3rd , and we now know more about AMD ’s solution to theRTX 40 Series .

Dr. Su begin the presentment by mull on the Ryzen 7000 Series release and stating AMD ’s ambitious finish , much like she did during the previous presentment . For RDNA3 , she repeat the troupe ’s commitment to DOE efficiency and performance .

“ At the forefront of what we ’re doing , it ’s all about power and energy efficiency . We desire to make trusted that we continue to introduce around performance - per - watt leadership to enable all of the gamer upgrade with fantastic performance , but at a reasonable power . ” – Dr. Lisa Su

start with the fresh chiplet design , RDNA 3 take a modular approach with the intention of optimizing the efficiency of the overall GPU design . Much like the Ryzen CPU class , RDNA3 will utilize a mixed chiplet computer architecture . With a 5 nm graphic dice ( GCD ) compute unit contain all of the shaders , video display engines , and update medium engine , the GCD is pair with a 6 nanometre Memory Cache Die ( MCD ) that dwell of the GDDR6 controller as well as 96 MB of AMD ’s Infinity Cache–2nd Generation Infinity Cache , that is !

With this new intention , the RNDA 3 chiplet will have an interconnect speed of up to 5.3 TB / s ( a 2.7x increase over RDNA 2 ) , enable up to 61 TFLOPS of compute . All of this will be support by up to 24 GB of GDDR6 with a memory motorcoach up to 384 - number ( not the GDDR6X we realize in the RTX 4090 ) and , according to Dr. Su , will enable RDNA 3 GPUs to achieve up to 54 % greater performance - per - watt over the old coevals .

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

The Radeon RX 7900 XTX comes with 24 GB of GDDR6 and Radeon RX 7900 XT come with 20 GB of GDDR6 . Engineered as both 4 KB and 8 K play GPUs , the Radeon RX 7900 XTX and 7900 XT have a number of update over the previous generation that will help push it into the time to come of play .

start out with dedicated AI acceleration , RDNA 3 is said to improve AI - base single-valued function of the GPU by 2.7x and ray tracing instructions by 1.8x over RDNA 2 . In rendering applications – including ray trace , this novel architecture is tell to incur up to 50 % more execution per compute unit of measurement and double the instructions per clock . This is a much - needed leap for Radeon graphics to compete within this particular space of art processing !

But , there ’s more :

AMD ’s new Radiance Display is the engine campaign all of that data into the display . The engine will support 12 bit - per - channel people of color with up to 68 billion colour as well as higher refresh rate . Thanks in no little part to DisplayPort 2.1 and HDMI 2.1 acceptance , the RX 7900 XTX and RX 7900 XT will support refresh rates of up to 900 Hz at 1440p , 480 Hz at 4 K , and 165 Hz at 5K.

Alongside of the Radiance Display engine , AMD also unveiled a newfangled dual media engine for simultaneous encode and decode for both AVC and HEVC formats . This engine will also support AV1 encryption and decoding , with a max resolution of 8K60 . Later on in the presentation , AMD teased future support for AV1 encoding support within OBS as well as other popular video cyclosis and editing software . This teaser also admit a next feature article called SmartAccess Video , which will leverage Ryzen CPUs and Radeon GPUs together to purportedly provide up to a 30 % uplift in 4 K multi current encryption .

When it comes to gambling performance , the RX 7900 XTX is purported to function up to 1.7x better than AMD ’s former flagship GPU , the Radeon RX 6950 XT , in rasterization and up to 1.6x well in ray trace game . Using FidelityFX Super Resolution ( FSR ) , the charts AMD showed for the 7900 XTX record several title run at frame rates far surpass 200 FPS at 4K. One standout was Valorant , which prove the RX 7900 XTX guide at 704 FPS ! Lots of sheer claims here , but we ’ll have to see for ourselves once the cards are in the deal of third - political party reader !

When it comes to the actual specifications , the RX 7900 XTX will have 96 compute units with a game clock of 2.3 GHz . All of this is said to fly the coop at a total board power lot of 355 W. For circumstance , that is 95 W less than NVIDIA ’s RTX 4090 Founder ’s Edition while vacillate close to the RX 6950 XT ’s typical circuit board power . The RX 7900 XT will have 84 compute units with a plot clock of 2 gigacycle per second and a full panel power of 300 W.

Oh yeah , and neither one of them will require a special cable to power them .

This is just the hardware , though . AMD took some prison term to talk about FSR acceptation , the upheaval in performance seen within FSR2 , and how well RDNA 3 operates with it enable . One example the company showed off was Ubisoft ’s Assassin ’s Creed : Valhalla running at 96 frames per second at 8K. It was a short clip , but jolly wild to see all the same . But AMD wanted us to lie with that FSR is n’t stopping at FSR2 . There ’s a newfangled iteration , FSR3 . At the fourth dimension of the promulgation , AMD said that Radeon users can expect up to 2x more frames per second over FSR2 and that the technology would be useable in 2023 .

uphold the conversation about software program , AMD ’s Frank Azor shared updates to Radeon Adrenaline software program , including a unexampled feature coming in the first half of 2023 called AMD HYPR - RX . This lineament will be a one - release optimizer to give AMD organisation the well potential performance without having to make all of the adjustments yourself .

Team Red also shared its dedication to provide the good CPU and GPU unified experience by working with system planimeter to get the AMD Advantage line to the desktop platform . This mean pairing AMD GPUs and CPUs together in system constellation carefully curated by AMD for the supposed best potential AMD experience .

The Radeon RX 7900 XTX and Radeon RX 7900 XT will be available on December 13th , 2022 . And the cost ? $ 999 and $ 899 USD , respectively . This is an awful eminence from NVIDIA ’s $ 1599 flagship .
