AMD's RDNA 3 GPUs are Way Cheaper Than the RTX 4090 - Gizmodo

Back successful August, Dr. Lisa Su introduced the satellite to AMD’s newest iteration of CPU technology, the Ryzen 7000 Series–but she didn’t halt there. We got an announcement for an announcement: RDNA 3, AMD’s adjacent procreation of GPU technology. Well, contiguous is November 3rd, and we present cognize much astir AMD’s reply to the RTX 40 Series.

Dr. Su began the presumption by reflecting connected the Ryzen 7000 Series merchandise and stating AMD’s ambitious goals, overmuch similar she did during the erstwhile presentation. For RDNA3, she reiterated the company’s committedness to vigor ratio and performance.

“At the forefront of what we’re doing, it’s each astir powerfulness and vigor efficiency. We privation to marque definite that we proceed to innovate astir performance-per-watt enactment to alteration each of the gamer upgrades with fantastic performance, but astatine a tenable power.” - Dr. Lisa Su

Starting with the caller chiplet design, RDNA 3 takes a modular attack with the volition of optimizing the ratio of the wide GPU design. Much similar the Ryzen CPU family, RDNA3 volition utilize a mixed chiplet architecture. With a 5nm graphics dice (GCD) compute portion containing each of the shaders, show engines, and updated media engine, the GCD is paired with a 6nm Memory Cache Die (MCD) that consists of the GDDR6 controller arsenic good arsenic 96 MB of AMD’s Infinity Cache–2nd Generation Infinity Cache, that is!

With this caller design, the RNDA 3 chiplet volition person an interconnect velocity of up to 5.3 TB/s (a 2.7x summation implicit RDNA 2), enabling up to 61 TFLOPS of compute. All of this volition beryllium supported by up to 24 GB of GDDR6 with a representation autobus up to 384-bit (not the GDDR6X we saw successful the RTX 4090) and, according to Dr. Su, volition alteration RDNA 3 GPUs to execute up to 54% greater performance-per-watt implicit the erstwhile generation.

So, what is this magical enigma GPU? Well, it’s really 2 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 comes with 20 GB of GDDR6. Engineered arsenic some 4K and 8K gaming GPUs, the Radeon RX 7900 XTX and 7900 XT person a fig of updates implicit the erstwhile procreation that volition assistance propulsion it into the aboriginal of gaming.

Starting with dedicated AI acceleration, RDNA 3 is said to amended AI-based functions of the GPU by 2.7x and ray tracing instructions by 1.8x implicit RDNA 2. In rendering applications–including ray tracing, this caller architecture is said to get up to 50% much show per compute portion and treble the instructions per clock. This is simply a much-needed leap for Radeon graphics to vie wrong this peculiar abstraction of graphics processing!

But, there’s more:

AMD’s caller Radiance Display is the motor pushing each of that information into the display. The motor volition enactment 12 bit-per-channel colour with up to 68 cardinal colors arsenic good arsenic higher refresh rates. Thanks successful nary tiny portion to DisplayPort 2.1 and HDMI 2.1 adoption, the RX 7900 XTX and RX 7900 XT volition enactment refresh rates of up to 900 Hz astatine 1440p, 480 Hz astatine 4K, and 165 Hz astatine 5K.

Alongside of the Radiance Display engine, AMD besides unveiled a caller dual media motor for simultaneous encode and decode for some AVC and HEVC formats. This motor volition besides enactment AV1 encoding and decoding, with a max solution of 8K60. Later connected successful the presentation, AMD teased aboriginal enactment for AV1 encoding enactment wrong OBS arsenic good arsenic different fashionable video streaming and editing software. This teaser besides included a aboriginal diagnostic called SmartAccess Video, which volition leverage Ryzen CPUs and Radeon GPUs unneurotic to supposedly supply up to a 30% uplift successful 4K multi watercourse encoding.

When it comes to gaming performance, the RX 7900 XTX is purported to run up to 1.7x amended than AMD’s erstwhile flagship GPU, the Radeon RX 6950 XT, successful rasterization and up to 1.6x amended successful ray tracing games. Using FidelityFX Super Resolution (FSR), the charts AMD showed for the 7900 XTX showed respective titles moving astatine framework rates acold exceeding 200 FPS astatine 4K. One standout was Valorant, which showed the RX 7900 XTX moving astatine 704 FPS! Lots of bold claims here, but we’ll person to spot for ourselves erstwhile the cards are successful the hands of 3rd-party reviewers!

When it comes to the existent specifications, the RX 7900 XTX volition person 96 compute units with a crippled timepiece of 2.3 GHz. All of this is said to tally astatine a full committee powerfulness gully of 355 W. For context, that is 95 W little than NVIDIA’s RTX 4090 Founder’s Edition portion hovering adjacent to the RX 6950 XT’s emblematic committee power. The RX 7900 XT volition person 84 compute units with a crippled timepiece of 2 GHz and a full committee powerfulness of 300 W.

Oh yeah, and neither 1 of them volition necessitate a peculiar cablegram to powerfulness them.

This is conscionable the hardware, though. AMD took immoderate clip to speech astir FSR adoption, the uplift successful show seen wrong FSR2, and however good RDNA 3 operates with it enabled. One illustration the institution showed disconnected was Ubisoft’s Assassin’s Creed: Valhalla moving astatine 96 frames per 2nd astatine 8K. It was a abbreviated clip, but beauteous chaotic to spot each the same. But AMD wanted america to cognize that FSR isn’t stopping astatine FSR2. There’s a caller iteration, FSR3. At the clip of the announcement, AMD said that Radeon users tin expect up to 2x much frames per 2nd implicit FSR2 and that the exertion would beryllium disposable successful 2023.

Continuing the speech astir software, AMD’s Frank Azor shared updates to Radeon Adrenaline software, including a caller diagnostic coming successful the archetypal fractional of 2023 called AMD HYPR-RX. This diagnostic volition beryllium a one-button optimizer to springiness AMD systems the champion imaginable show without having to marque each of the adjustments yourself.

Team Red besides shared its committedness to providing the champion CPU and GPU unified acquisition by moving with strategy integrators to bring the AMD Advantage enactment to the desktop platform. This means pairing AMD GPUs and CPUs unneurotic successful strategy configurations cautiously curated by AMD for the expected champion imaginable AMD experience.

The Radeon RX 7900 XTX and Radeon RX 7900 XT volition beryllium disposable connected December 13th, 2022. And the price? $999 and $899 USD, respectively. This is an astonishing favoritism from NVIDIA’s $1599 flagship.

We look guardant to seeing conscionable however these GPUs execute retired successful the wild! Let america cognize successful the comments what you are astir excited for successful AMD’s announcement contiguous and if you program connected making an upgrade earlier the twelvemonth is through.
