Ok, sine Yuri (wisely) decided to rest for the weekend, here are a couple of hardware bits. Remember that one is a RUMOR.

Intel’s Mitigations For New Spectre V2 Exploit Affect CPU Performance, Up To 35% Drop
https://wccftech.com/intel-mitigations-spectre-v2-exploit-35-percent-drop-in-cpu-performance/
Branch History Injection (BHI), a new variant of the Spectre V2 vulnerability affecting several Intel processors and a handful of Arm cores, was announced earlier this week by VUSec, the Systems and Network Security Group at Vrije Universiteit Amsterdam. Linux site Phoronix performed tests showing a 35% drop in performance on the affected processors by the new BHI mitigations.

That 35% is for the i7 1185G7. For the i9 12900K, the max. drop is almost 27%.

While AMD was not affected by this new Spectre, Intel found something:

Intel Finds Bug in AMD's Spectre Mitigation, AMD Issues Fix
https://www.tomshardware.com/news/intel-amd-spectre-v2-vulnerability-mitigation-bug-fix-patch-cpu-security
News of a fresh Spectre BHB vulnerability that only impacts Intel and Arm processors emerged this week, but Intel's research around these new attack vectors unearthed another issue: One of the patches that AMD has used to fix the Spectre vulnerabilities has been broken since 2018. Intel's security team, STORM, found the issue with AMD's mitigation. In response, AMD has issued a security bulletin and updated its guidance to recommend using an alternative method to mitigate the Spectre vulnerabilities, thus repairing the issue anew.

And, as a result, Phoronix has also done some testing with AMD: https://www.phoronix.com/vr.php?view=30973

And here's the rumor:

AMD FSR 2.0 might be announced soon, “impressive performance and image quality”
https://videocardz.com/newz/amd-fsr-2-0-might-be-announced-soon-impressive-performance-and-image-quality
The developer of CapFrameX benchmarking and monitoring software claims to have seen the footage from the FSR 2.0 demo. This would be the first time a demo of AMD’s next-gen upscaling technology is mentioned.

According to the tweet, the FSR 2.0 is based on temporal upscaling, which would be a major shift from the current implementation of FSR. Interestingly, unlike XeSS and DLSS, no AI-acceleration would be required. This means that the technology could work with a wider range of GPUs. The developer claims it would be supported by all vendors, but does not mention which GPU architectures specifically.
