  • I'm using suspend on my desktop running Manjaro KDE. To reduce power usage it goes to sleep after 15 minutes of inactivity and wakes up on mouse or keyboard input. Aside from some flaky kernel versions and after underclocking an unstable EXPO profile it's pretty stable, even games continue to run after wakeup.

  • That monitor will hold it back. 1080p wouldn't be bad if modern games run without TAA blur, but most games require it. Even a cheap 144hz IPS 1440p will give you a better experience.

    • Yeah. So I guess the next question for me is, does that mean that FSR four is going to be exclusive to,
    • look, I would say it's right now it has to be because of what I just said. It requires a lot of compute to be able to generate the pixels.

    Just confirmed that at least on launch it will be RDNA4 exclusive. I just hope it can run on other hardware even if it is a dedicated NPU in mobile chips.

  • That ATX board would be great. The mATX B650M PG is also better than the previous one, it is good enough. If you can find the B650M-HDV/M.2 in stock that is even better if you don't need 3 m.2 slots.

    That monitor was indeed a lucky deal. It looks to be a good combination for this setup.

  • I don't think it's the scheduler this time with a single CCD, but there is significant difference. These tests focus on compute and productivity with almost no games, so most of the difference could come from this bias. Another possible option is the power profile (EPP balance_performance) holding back the 7700x on linux.

  • The draft is pretty good. Only a few points to consider changing:

    • That is an entry level Motherboard which may limit your upgrades in the future. It overheats with a 16 core ryzen 9.
    • The ram size is good, but the speed and latencies are just as important nowadays. A 6000 MT/s CL30 Expo ram could improve CPU performance, but it's a kind of OC so not every combination is fully stable at the highest speeds.
    • Especially with competitive and indie games it's easy to run them at high FPS. I would consider getting a 1440p high refresh rate (144+ Hz) monitor if you don't have one already. It's a huge upgrade coming from 1080p60Hz.
  • Permanently Deleted

  • As an Android flavour it should be safe after uninstalling all apps associated with the university. Did any of them need a "device owner" permission? That's the only way to be more persistent on Android without root access.

    Level1Techs - Intel has a Pretty Big Problem

    What's Being Done?

    13:30 - the systems deployed for both companies with either one of these processors to within one percentage Point are experiencing the same stability issues even disabling ecores has not fully resolved the issue for one of these companies the error rate also seems to be going up over time on the server side

  • The FS feature is great, it's just cumbersome to use without a tool.

    Snapper works well for a local backup like history both against botched updates and accidental deletion, but eats up the free space with the default settings.

    Timeshift is an easy to use GUI but doesn't support non-default partitions.

    Also the quota support had a nasty side effect: freezing the whole system on snapshot deletion.

  • I think calling it a "cache" is not precise. The primary function of the DRAM is to hold the dictionary for translating logical addresses (e.g. sectors) from the OS to the physical addresses (which NAND chip, which bank etc.). This indirection is needed for the controller to do wear leveling without corrupting the filesystem.

    On a SATA SSD without DRAM each read IO could mean 2 actual reads: first the dictionary to find the data and than the actual data being read. As you said HBM helps by eliminating this extra read.

    The read and write caching is just a use of the remaining DRAM capacity. Since modern Operating Systems use the general RAM for the same function it is usually just a small increase to the throughput.

    An Interview with Pat Gelsinger - More Than Moore

    Video version: https://youtu.be/0PrmrMQ9gJU

    In February 2024, Intel held its first Intel Foundry Direct Connect event. [...] The tone of the event was one of success – Intel Foundry (IF) is set to be a semi-autonomous body of Intel that aggressively fights for business, whether Internal or External, without playing favorites.

    [...]

    Ian: It’s been said in the past that Intel bets the whole company on the next process node, is that still true?

    Pat: I’ve bet the whole company on 18A. We have committed products to this - it is the culmination of our 5 nodes in 4 years. So bringing that across the line, in that sense yes - I’ve bet the whole company on making this successful.

    TAA is a crucial tool for developers - but is the impact to image quality too great?

    For good or bad, temporal anti-aliasing - or TAA - has become a defining element of image quality in today's games, but is it a blessing, a curse, or both? Whichever way you slice it, it's here to stay, so what is it, why do so many games use it and what's with all the blur? At one point, TAA did not exist at all, so what methods of anti-aliasing were used and why aren't they used any more?

    NVIDIA GH200 CPU Performance Benchmarks Against AMD EPYC Zen 4 & Intel Xeon Emerald Rapids Review

    Here are some initial benchmarks of the Grace CPU performance while the Hopper GPU benchmarks will be coming in a follow-up article.

    NVIDIA's GH200 combines the 72-core Grace CPU with H100 Tensor Core GPU and support for up to 480GB of LPDDR5 memory and 96GB of HBM3 or 144GB of HBM3e memory. The Grace CPU employs Arm Neoverse-V2 cores with 1MB of L2 cache per core and 117MB of L3 cache.

    On a geo mean basis across all the benchmarks conducted, the GH200 Grace CPU performance nearly matched the Intel Xeon Platinum 8592+ Emerald Rapids processor. The Arm Neoverse-V2 based Grace CPU tended to be much faster than the 128-core Ampere Altra Max AArch64 server.

    Overall the NVIDIA GH200 CPU benchmarking was quite fascinating to see its early potential. There still are some workloads not too well optimized for AArch64 and in some cases the higher core counts and dual socket configurations available with Intel Xeon Emerald Rapids and AMD EPYC Genoa(X) / Bergamo could drive the results much hig

  • Thanks for the links! I updated my config from z3fold to zsmalloc and adjusted the vm.page-cluster to test these out.

    Reading a bit more, I think when using large max_pool_percent (>30) with Zswap the two solutions are more similar than not. A crucial difference is what use-case is more acceptable since Zswap can cause unresponsiveness (and potential lockup) under high memory pressure. While Zram could result in an OOM crash in a similar worst-case scenario.

  • Stormgate

    It's like 90% StarCraft 2 and 10% Warcraft 3. The competitive RTS part is promising but it didn't show me anything new. Depending on the lore and campaign it may get more interesting, so far it's neutral.

    Millennia

    It starts very similarly to Civ 6 with even more kinds of resources. The current version of the UI seemed confusing and the poor performance (on linux) stopped me from finishing the demo.

  • Even tough IPv6 is technically superior to IPv4 for the network operator it doesn't have clear benefits for home users.

    Having global addresses instead of NAT means less control over your LAN and these unique public addresses can track users more accurately.

  • Btrfs with compression enabled and subvolumes set.

    And enable/automate maintenance services for BTRFS. For example: balace should be run on heavily used system disks or scrub could help detect errors even on single disks.

    ZRAM (With proper sysctl.conf like PopOS does).

    Could you explain the preference of ZRAM over ZSWAP? I thought the latter was the more advanced and better performing solution. Is there some magic in Pop's config?

    AMD EPYC Bergamo is a Fantastically Fresh Take on Cloud Native Compute

    While today we have both the AMD EPYC “Genoa-X” and “Bergamo” launches, Bergamo is clearly the more impactful of the two. That is a lot to say given we know that Microsoft Azure is very fond of Milan-X and Genoa-X. Let us put together a few key points:

    • The primary change for Zen 4c cores from Zen 4 is a halving of L3 cache.
    • The AMD EPYC 9754 is showing performance ~3x a 128-core Arm competitor at 1.5x the power.
    • An AMD EPYC 9754 is often twice the performance of 2019’s AMD EPYC 7002 “Rome” 64-core parts.
    • On most non-HPC-focused workloads, expect the AMD EPYC 9754 to be 15-20% faster than the AMD EPYC 9654. That is not a straight 33% as we would expect due to the core count increase, but AMD is getting scaling from the increased core count even with a drastically reduced L3 cache size.
    • AMD seems to have figured out an elegant way to reduce turbo clock jitter, especially at maximum load. That helps a lot with SLA on a loaded system.
