With the launch on the horizon, you could have just a few questions concerning the upcoming RDNA 3 playing cards
Up to date: Nov 2, 2022 12:03 pm
The yr 2020 was an thrilling one for consoles and PCs alike. We acquired the eagerly anticipated next-gen consoles from Xbox and Sony along with brand-new CPU and GPU releases from AMD and NVIDIA.

These variations noticed appreciable efficiency will increase over their predecessors, primarily as a result of TSMC and Samsung switched to a smaller (7nm) manufacturing course of. AMD intends to base its RDNA 3 and Zen 4 structure on the TSMC-developed 5nm expertise. In consequence, we’ve excessive hopes for elevated efficiency.
We hope a brand new technology of RDNA structure will likely be produced utilizing TSMC’s 5nm manufacturing expertise. The whole variety of streaming processors is 12288 with 6 Shader Engines and simply 48 WGPs, which is considerably fewer than what was beforehand talked about in leaks.
However, that’s twice as many cores because the RX 6900 XT (5120 SPs). A number of reviews have been making the rounds that Navi 31 could function a TDP of 450W, however nothing has been confirmed.
Based on Robert Hallock, the PCIe model is far much less vital for GPUs than for storage, which is why AMD is offering PCIe 5 with numerous choices relying on the chipset.
All chipset variations embody two slots, however PCIe 5 shouldn’t be required for GPUs except they’re extraordinarily costly. As a result of capacity to transmit knowledge seamlessly, DirectStorage video games will function way more detailed worlds and therefore want far more bandwidth.
The efficiency will likely be extra negatively impacted as a result of they may use it throughout gaming moderately than simply when a stage is loaded. Nevertheless, the GPU gained’t be the bottleneck (for x16 playing cards) with PCIe 4.0 as a result of PCIe 5.0 x4 has the identical bandwidth as PCIe 3.0 x16.
On November 3, 2022, AMD is anticipated to webcast the introduction of a minimum of a few of its RDNA 3 graphic playing cards. Though there may be little info accessible but, latest leaks and reviews point out that the enterprise will reveal three GPUs at its occasion.
Will RDNA 3 have ray tracing? Will it’s higher
There isn’t a doubt that upcoming AMD RDNA 3 graphics playing cards will carry out higher than its present technology Radeon equivalents. Nonetheless, group pink retains quiet about how a lot of an improve we will anticipate.
These new RDNA 3 architecture-based graphics playing cards could have greater than twice the ray tracing efficiency of their forerunners. Based on reliable {hardware} leaker Greymon55, the brand new structure also needs to enhance body charges in normal rasterization by an element of “2X.”
No matter whether or not these claims are compared to the Radeon 6950 XT or 6900 XT, they characterize a exceptional potential enchancment. The Nvidia RTX 4000 series is the place this potential RDNA 3 flagship will shine the brightest.
Though the aim of those “elevated ray tracing capabilities” is unknown, it must be clear that the next-generation AMD RDNA 3-based Radeon RX 7000 collection GPUs could have greater than sufficient ray tracing efficiency and new (and improved) options. NVIDIA is the undisputed chief in GPU ray tracing. Thus AMD will likely be higher capable of struggle in opposition to it, however RDNA 3 gained’t be enjoying round.
It is going to take one thing distinctive to cease the Lovelace card’s “absurd body charges,” as we wrote in our Nvidia GeForce RTX 4090 review. In comparison with Nvidia DLSS, AMD FSR 2.0 did assist stage the enjoying subject, however group inexperienced’s “Body Era” operate could possibly be too difficult to beat.
We is likely to be in for a royal brawl on the AMD RDNA 3 unveiling when two Radeon GPUs compete in opposition to the RTX 4000, particularly for the reason that Nvidia RTX 4080 will likely be unveiled in November. The AMD Radeon RX 6900 XT, which prices just below $700, is probably the most reasonably priced graphics card ever proper now should you want one to your laptop.
“RDNA 3 can also be the primary GPU structure that can leverage the improved 5nm course of and superior chip expertise. One other innovation contains architected items with enhanced ray-tracing capabilities and an optimized graphics pipeline with even quicker clock speeds and improved energy effectivity,” stated David Wang, AMD’s SVP of Engineering at Radeon Applied sciences Group.
Will RDNA 3 have AV1 encoding?
Based on Linux driver patches provided by AMD and located by @Kepler_L2 on Twitter, AMD’s RDNA 3-based GPUs with VCN 4.x engines help {hardware} AV1 encoding. It was incorrectly said beforehand that AMD’s future Radeon RX 7000-series GPUs didn’t help AV1 encoding primarily based on Linux patches.
With a view to proceed enabling AMD’s RDNA 3 GPUs, the agency has offered quite a lot of patches for Linux that provide details about the corporate’s forthcoming Video Codec Subsequent model 4.x video engines.
Based on the information we’ve, VCN 4.x helps the decoding of just about all modern codecs. Along with AV1, H.264, and H.265 encoding, AMD’s VCN 4.0 engine appears to be like to deal with H.264/MPEG 4 AVC, H.265, VP9, AV1, and JPEG decoding.
VCN doesn’t but seem to permit decoding or encoding of H.266/VVC (versatile video coding). When the correct content material turns into accessible, VVC, a next-generation codec, will doubtless be mandatory for 2023 or 2024, and AV1, a current-generation codec, will doubtless proceed to develop in utilization.
Though some customers and companies would favor to have it now to be able to encode or transcode video, later this yr must be enough.
The one chips that presently help AV1 decoding and encoding are Intel’s Arc Alchemist GPUs. Though it hasn’t been verified but, we anticipate Nvidia’s future Ada structure might also allow AV1 encoding.
Whereas AMD’s RDNA 3 gained’t be accessible available in the market till later this yr, if AMD’s VCN 4.x does truly help AV1 encoding, all three main GPU producers will present hardware-accelerated AV1 encoding and decoding.
Talking of VCN 4.0, even the current VCN 3. x engine totally helps each H.264 and H.265 encoding and decoding for H.264/MPEG4 AVC, H.265, VP9, AV1, and JPEG. The principle development in VCN 4.0 over 3.x will likely be hardware-accelerated AV1 encode/decode performance, barring additional developments.
