The Hot Take: Well now....
AMD appears to have yanked a memory encryption protection from consumer Ryzen chips, leaving users to play firmware detective.
For those who came in late: a decade ago, AMD added Transparent Secure Memory Encryption (TSME) to higher-end CPUs to protect systems from cold-boot attacks and other physical exploits that can siphon data from memory. The feature encrypts everything stored in RAM, making stolen memory contents useless to attackers with physical access.
Over time, TSME turned up on cheaper Ryzen consumer chips, and privacy-minded users reasonably started treating it as part of the package.
Recently, without warning, that protection vanished from lower-end AMD chips in a way Windows users could not easily detect and Linux users could spot only with some technical faffing.
According to Ars Technica AMD has not explained why TSME worked on these CPUs or fully confirmed the change, saying only that TSME âis a security feature only applied to PRO CPUs as part of AMD PRO Technologies.â
In April, Linux hobbyist Ben Kilpatrick installed a new operating system on a Ryzen 7 9700X system and ran Host Security ID to check firmware and hardware protections. He found HSI reporting âencrypted RAM: not supportedâ, even though TSME had been enabled in BIOS and had previously shown as âencryptedâ.
Kilpatrickâs digging led MSI engineers to test consumer Ryzen chips on MSI and Gigabyte boards, where older AGESA firmware enabled TSME but newer AGESA 1.2.7.0 showed it as unsupported.
Pro Ryzen chips supported TSME across motherboard brands and firmware versions, which rather spoiled the idea that this was just a random board-level wobble.
âThe big outstanding question is whether this is a deliberate policy decision by AMD to restrict TSME to PRO chips, or an unintentional regression that was introduced in AGESA 1.2.7.0,â Kilpatrick told Ars.
After Kilpatrick filed a bug report on AMDâs public engineering GitHub, AMD fellow software engineer Tom Lendacky suggested toggling the BIOS option and then speaking to MSI if that failed.
AMD senior principal software engineer Mario Limonciello gave similar advice, telling him: âIf it still doesnât work; then yes please report it to your board vendor to debug.â
Kilpatrick later said MSI had been told by AMD that TSME was officially supported only on PRO processors, and tests showed TSME active on a Ryzen 9945 PRO but off on a consumer Ryzen 9800X3D.
MSIâs ABL dump comparisons reportedly showed the internal AGESA flag DfIsTsmeEnabled returning FALSE for consumer chips, even when TSME was set to AUTO or ENABLED in BIOS.
Kilpatrick pressed AMD on whether this was a silicon limitation or a firmware policy decision, because one is fixed and the other could be changed.
Limonciello replied: âMy apologies, but I donât have any more information to share on this topic.â
This is embarrassing as Lendacky said in 2020 that a consumer Ryzen 3700X âshould support TSMEâ, and in 2025 recommended using it if the BIOS exposed the option.
Silicon-level security expert Joe Fitzgerald said: âBut I really feel like an explanation should be in order, even if it was âTSME was never supposed to be supported. We did ship some firmwares that erroneously enabled it, but you shouldnât use them since we canât guarantee itâll work properly.ââ

The Hot Take: This is an interesting collaboration between the two seeing intel keeps saying they're not going to stop GPU development.
Intel's Serpent Lake SoCs featuring NVIDIA's RTX GPU tiles as integrated graphics are expected to roll out by Q1 2028. Intel & NVIDIA's Co-Developed Serpent Lake SoCs Featuring Next-Gen CPU & GPU Architectures Rumored For Q1 2028 Last year, Intel announced that it was working with NVIDIA on a custom SoC that would incorporate NVIDIA's RTX GPU tiles. Intel stated that these SoCs will power a wide range of PCs that require the integration of these levels of CPUs & GPUs together into a single package. It looks like we have our first timeline of when these SoCs will be [âŚ]Read full article at https://wccftech.com/intel-serpent-lake-socs-with-nvidia-rtx-gpu-tiles-reportedly-arrive-in-q1-2028/

The Hot Take: ARM seems to be breaking out from everywhere. Fujitsu, Nvidia, AWS and ARM. Qualcomm seems to be playing catch up in the server market from the looks of it.
AWS has provided a first look at its next-generation Graviton5 processor, a custom server CPU developed by Annapurna Labs for deployment across the company's cloud computing platform and AI inference infrastructure.

The Hot Take: Question is, do I go HPDT with Z990 or Consumer Z970? I guess I'll have to see the benches on if HPDT does anything for Gaming.
The Z990 PCH for Nova Lake motherboards is apparently 22% smaller than Z890, despite featuring a higher power maximum power draw of up to 14W. The leaked picture of the PCH shows a 11.15 x 6.5mm die and 25 x 24mm package, but we're unsure what motherboard it actually comes from.

The Hot Take: Motherboard bending = BAD.
Intel appears to be cooking up a beefier Nova Lake socket clamp to stop its future desktop chips getting bendy or crispy.
If you are a hardware enthusiast, you probably know Intelâs independent loading mechanism, or ILM, can warp CPUs over time. The ILM is the retention clamp that holds the CPU in the socket, which sounds dull until your chip starts looking like a Pringle.
According to Hot Hardware Chipzilla released a reduced-load version of the ILM with Arrow Lake, which mostly fixed the issue, but made it optional. Now Chipzilla appears to have another ILM variant coming with Nova Lake. This one looks less about correcting curvature and more about dealing with high current.
Older processors used pin grid array sockets, or PGA, where the pins sat on the CPU itself. Modern chips use land grid array sockets, or LGA, where the pins live in the socket instead.
LGA has plenty of advantages, including denser pins, better electrical performance and CPUs that are less likely to be mangled by ham-fisted builders. The downside is that it needs a precise compression force to ensure the CPU and socket contact each other properly.
That is why Intel uses ILMs, whileâŚ

The Hot Take: Creeps back into the chips...
AMDâs Zen 5 looked efficient, but weak demand and a dodgy RDSEED bug have taken the shine off.
For those with long memories, AMDâs Ryzen 9000 series arrived in 2024, promising strong efficiency and decent IPC gains. Months later, the launch looks messier. Sales were soft, prices fell quickly, and a documented random-number flaw has spooked some buyers.
The line-up included the 16-core Ryzen 9 9950X, 12-core 9900X, eight-core 9700X and six-core 9600X. Early benchmarks were mixed. Gaming gains were often single-digit at higher resolutions, while productivity wins varied by workload.
Reviewers liked the cooler running and lower power use, but Zen 4 owners saw little reason to upgrade. AMD leaned harder into X3D chips, where stacked cache delivered clearer frame-rate gains for gamers.
According to Webpro News in late 2025, AMD detailed an RDSEED flaw affecting all Zen 5 processors. The bug, tracked as AMD-SB-7055 and CVE-2025-62626, hits the 16-bit and 32-bit versions of RDSEED.
They can return zero far more often than proper randomness allows, while the carry flag still reports success. That means software trusting the hardware output can swallow predictable data, which is grim news for cryptography.
Linux patches moved to disable the affected instruction or use other sources, but AMD has not issued a recall and points to microcode and software mitigations.
By early 2026, AMD was preparing refreshed SKUs to counter Intelâs Arrow Lake updates. Leaks pointed to Ryzen 7 9750X and Ryzen 5 9650X models with higher TDPs, higher clocks and improved memory support in some setups.
That looks like squeezing more speed from existing silicon. Power rises and Zen 5âs efficiency pitch gets thinner. Corporate buyers have reason to wait until mitigations are stable. Gamers are likely to favour X3D models, which offer clearer frame-rate gains and less early-launch baggage.
Server and workstation buyers have more to worry about because secure boot, VPNs and database encryption depend on reliable entropy.
Zen 5 still brought gains in branch prediction, cache design and TSMC N4P fabrication. The RDSEED bug does not erase that work, but it exposes an awkward validation gap.
AMD keeps shipping Zen 5 parts, and AM5 support remains a useful strength. Still, modest adoption, a documented RNG flaw and fast refresh plans make Zen 5 look less tidy than AMD wanted.
System builders running cryptographic workloads should avoid first-wave Zen 5 chips unless mitigations are tested. Everyone else should look harder at refreshed SKUs or X3D parts while AMD patches the trust problem.
