AMD Memory Guard (Transparent Secure Memory Encryption, or TSME) is a hardware-based memory encryption technology available on our Ryzen PRO desktop and mobile processors where supported in silicon. It is a foundational security feature, and we have no plans to remove support from our Ryzen PRO lineup. This commitment holds now and in the future.
Regarding certain non-PRO Ryzen 9000-series desktop processors, a BIOS option to enable Memory Guard was previously available but was removed in a recent update. Based on valuable community feedback, we will reinstate this option in an upcoming BIOS release in July."

-Fran- Strange PR W for AMD. Let's celebrate while it lasts. So… Intel will give AVX512 back to the people with Alder Lake? LOL Regards. Reply

B0 had it enabled and they patched it with a BIOS microcode update. EDIT: https://www.tomshardware.com/news/how-to-pick-up-an-avx-512-supporting-alder-lake-an-easy-way Regards. Reply
usertests This, FSR4, ROCm, etc. There's a culture of hostility and paranoia between AMD and its users developing. -Fran- said: So… Intel will give AVX512 back to the people with Alder Lake? LOL They had "good" reasons to disable it, and will finally "give" it back soon, not to old CPUs, but with the Nova Lake AVX10 kludge they had to create to get P-cores and E-cores to play nice with it. AMD will adopt AVX10 in the future, so I wonder if they will be using it for their own "LP" cores that might not be able to execute full-width AVX-512. Between new (and old) instructions in Nova Lake, a viable X3D competitor in bLLC, and maybe an eventual goal of eliminating E-cores by the end of the socket, Intel is probably worth a second look. Unclear is whether they will decide to credibly challenge Strix/Gorgon/Medusa Halo with "AX" models. Intel could be abandoning Xe graphics in the long run for Nvidia graphics. AMD may be eliminating the iGPU on Zen 6 (Olympic Ridge) to provide a big NPU only, while Intel will continue to provide both with Nova Lake. That's got my attention. Reply

"It's ok guys; just buy the new thing". No? As for the NPU rumour. I've never found having an iGPU on a dedicated "CPU" SoC really useful. I rather the die space is used on something else that can better the CPU SoC performance instead. But that's me. I do recognise it can be useful, but you can go read my long rants from the past about it, if you want. There's plenty, if you're curious about my position on the subject. So, in short: I could not care less they're removing the iGPU. If I had a complaint, I rather they get rid of the NPU as well. I don't see how that could be useful as a general purpose accelerator in the SoC. Also, they could use a dual purpose "NPU", since at the end of the day, to display image on screen, you don't really need fully DX12/VK compliant units and just video out. Look at Matrox in the server segment. Regards. Reply

If you cared for ai..you'd have them with modern GPU (in form of tensor cores) Reply
hwertz Yeah, Intel absolutely could have kept AVX512 going on those systems. AMD used 256-bit (AVX2) hardware plug microcode to provide AVX512 on certain processors, and Intel actually did as well. I have no idea why they didn't just do this on the E-Cores (instead of having it on the P-Cores, and not the E-Cores; then disabling it on both later on.) Reply
