AMD Launches RDNA 3, RX 7900 XT and XTX, Its Next-Gen GPU and Tech

Of their conventional goliath two-step, AMD follows Nvidia’s contemporary GeForce RTX 4000/Ada Lovelace structure debut with its competing sequence, the Radeon RX 7000 line, and its personal structure improve, RDNA 3. The primary two playing cards out of the gate would be the RX 7900 XTX and RX 7900 XT, transport on Dec. 13, for $999 and $899, respectively. 

Each playing cards are supposed for 4K, excessive body charge, prime quality gaming and streaming, however AMD’s additionally pitching the XTX as an 8K gaming GPU. And to end up 8K is coming, the corporate teased an upcoming Samsung Odyssey Neo G9 8K widescreen track slated for its professional announcement at CES in January. The corporate additionally says that we’re going to be seeing high-res DisplayPort 2.1 screens beginning at first of 2023 from corporations like Dell, Asus, LG and Acer and Samsung.

Along with AMD’s in-house playing cards, third-party playing cards can be to be had from AMD’s same old companions, akin to Asus.


8K? Neatly, RDNA 3 and the brand new GPUs upload fortify for DisplayPort 2.1, which has the bandwidth essential to fortify 165Hz 8K at 12 bits in step with colour (up from 10 bits) for HDR and to permit complete gamut protection of Rec.2020, or as much as 480Hz in 4K. That is a hyperlink bandwidth of as much as 54Gbps, up from 20Gbps in DP 1.4a, which Nvidia’s playing cards nonetheless use. 

Take into account that GPUs are normally neatly out entrance of screens in terms of colour and bit intensity, even though. (So get able for meaningless, breathless exclamations of “68 billion colours!” in track advertising and marketing fabrics.)

DP 2.1 works along side AMD’s new Radiance Show Engine, which additionally helps as much as 8K/60p simultaneous HEVC encoding and interpreting (a spice up for streamers), AV1 encode acceleration and AI-enhanced encoding by means of devoted AI acceleration silicon.

RDNA 3 structure improves on RDNA 2 in different tactics. It is the first GPU constructed from chiplets, the modular construction blocks of contemporary processor design. 

For something, it lets in AMD to make use of other procedure sizes at the identical die, on this case a 5nm graphics core and 6nm reminiscence cache die. This may end up in the power to optimize efficiency of the 2 one at a time, to squeeze in additional energy or velocity the place it does probably the most excellent, and in the end are compatible a greater processor in the similar house and gear envelope as previous fashions.

It permits AMD so as to add devoted AI acceleration and progressed raytracing accelerators — a weak spot it is historically had as opposed to Nvidia’s RTX cores — and to decouple the reminiscence clock speeds from the compute unit speeds to assist preserve energy draw. AMD claims the GPU will get higher DirectX raytracing (DXR) efficiency.

The chiplet dies incorporate second-generation Infinity cache, which streamlines use of to be had reminiscence over the sooner model, that means it does not must come out to machine reminiscence as a lot — a sooner and decrease latency way.

And SmartAccess Video joins the corporate’s different “sensible” applied sciences, like Sensible Get entry to Reminiscence. On this case, in case you have a machine supplied with a Ryzen 7000 CPU and RX 7000 GPU, it could distribute encoding and interpreting duties between the 2 for higher efficiency. That is coming beginning in December.

AMD Benefit Desktops

SAV components into the corporate’s new spouse program for desktops very similar to its AMD Benefit for laptops, which principally manner a machine makes use of all of the state-of-the-art AMD applied sciences, in addition to powerful cooling (with a liquid-cooled CPU), top rate machine design with tool-free access, no less than 32GB DDR5 reminiscence and an 80 Plus Gold energy provide.

This system appears to be supposed for custom-build corporations — no less than to start with — for the reason that the highlighted checklist of companions are CyberPower PC, Falcon Northwest, Maingear, Starting place PC and the like.

FidelityFX Tremendous Answer 3 and Adrenalin

AMD did not supply any main points for the largest replace to its efficiency optimization algorithms (I simply cannot name it and DLSS “upscaling” anymore, since they have each grown considerably past the ones roots), FSR 3, however at the floor, “Fluid Movement Frames” sounds an terrible lot like Nvidia’s Body Era, the largest improve to DLSS 3. 

If it does the similar factor, Fluid Movement Frames complements speculative rendering from “what does this pixel appear to be within the subsequent body” to “how is the following body other and the way does that translate to adjustments in a given pixel” for decrease latency with out element loss in detailed scenes.

AMD’s Adrenalin gaming hub-slash-optimization application will even introduce a notable new function within the first part of 2023, dubbed “Hyper-RX” mode: It’s going to be a one-click optimizer for efficiency and latency that takes into consideration all of the settings you would typically have to seek down and tweak personally. It is geared toward the ones folks who like “sooner,” however can are living with out the effort brought about by way of tweaking for “quickest.”
