This discrepancy between marketed and measured performance has fueled speculation of a bug in the Navi 31 GPU. Multiple sources have since confirmed that AMD is developing a revised version of Navi 31, also known as RDNA3+. However, the latest news is that AMD has canceled the development of RDNA3+.

Multiple media outlets reported in November 2022 that AMD was developing a Navi 31 GPU with a clock frequency above 3.0GHz. The report also states that this revised Navi 31 GPU will be used on the Radeon RX 7990 XTX, RX 7950 XTX, and RX 7950 XT graphics card PCBs. This possible update is known as RDNA3+ in the market.

But hardware leaker @All_The_Watts said in his latest tweet that AMD has canceled RDNA3+.

The tweet stated that all RDNA3+ SKUs developed by AMD have failed to meet performance and efficiency goals, and all prototypes have been sealed.

@All_The_Watts has previously stated that both the flagship Navi 31 and the mid-range Navi 33 in the RX 7900 XT/XTX have the same hardware bug, but this bug was discovered too late to be properly dealt with. The AMD team wants a “truly comprehensive fix” in RDNA 3+.

In addition to @All_The_Watts, Paul of RedGamingTech, another reliable breaking news channel, also heard similar news from some internal sources.

However, some of Paul’s sources believe that AMD is still developing RDNA 3+, but the release time has been significantly delayed. The news also clearly stated that the mid-range Navi 33 and Navi 32 have not been affected, and AMD will soon launch related graphics cards.

The first batch of RNDA 3 graphics cards has been released for less than 2 months, and it is too early to tell whether AMD has axed RDNA3+. Only time will tell if AMD actually decides to scrap RDNA 3+ graphics cards entirely.

AMD’s details page that the memory support capacity of AMD Ryzen 7040HS series processors has reached 256GB, while the previous generation Ryzen 6000HS series only supports 64GB.

In terms of memory frequency, the latest 7040HS series supports DDR5-5600 and LPDDR5x-7500, which is improved compared to the old models.

AMD Ryzen 7040 HS series model parameters are as follows:

R9 7940HS: 8 cores 16 threads, up to 5.2GHz, 40MB cache, 35-45W TDP

R7 7840HS: 8 cores 16 threads, up to 5.1GHz, 40MB cache, 35-45W TDP

R5 7640HS: 6 cores 12 threads, up to 5.0GHz, 38MB cache, 35-45W TDP

The notebooks equipped with Ryzen 7040 HS series processors will be available in March 2023.

As noted a few months ago, however, recent AMD graphics code work has focused on enabling new GPU instructions based on IP blocks, rather than bringing a huge patch in one fell swoop.

The pull request of the day mentioned a number of DCN improvements, as well as MMHUB, SMU, VCN and the other IP blocks that make up the next generation of AMD GPUs.

With AMD’s incremental approach, it’s hard to tell exactly where it is already, but let’s hope that Linux 5.20 brings good enough support for the Radeon RX 7000 series “RDNA 3 GPUs”.

It is planned that the Linux 5.20 merge window will open around late July, while the stable release will not be available until around late September.

Referring to the legendary AMD release schedule, both Linux 5.20 and Mesa 22.2 are expected to provide stable upstream kernel support at the beginning of the RDNA 3 graphics card release.

Finally, in addition to the enablement of new modules, the day’s AMD DRM-Next update includes a variety of fixes — from eDP display to USB-C and other issues.

There is also initial support for devcoredump, enabling high-priority graphics queues for compatible GPUs, GPU reset improvements, ASPM power management support for more GPUs, and various other changes.
