    Ryzen 7 5800X3D: No need for high-end RAM

    Posted: 24 Apr 2022 06:57 PM PDT

    The Ryzen 7 5800X3D have a "weakness" on memory scaling performance: DDR4/3200 vs DDR4/3800 give just +1% more performance at gaming.

    Simple Reason: The 3D V-Cache just works. The bigger Level 3 cache reduce the amount of memory accesses, so the memory performance become less important.

    Maybe this is truly an advantage / a strength: There is no need for high-end DDR4 for the Ryzen 7 5800X3D. The CPU works good with "potato RAM" as well.

     

    Ryzen 7 5800X3D Memory Gaming Perf. Test Settings
    Quasarzone DDR4/3200 CL22 vs DDR4/3800 CL16 +1.4% 5 tests @ 1080p, avg fps
    TechSpot DDR4/3200 vs DDR4/3800 +1.3% 8 tests @ 1080p, 1%lows
    Tom's Hardware DDR4/3200 vs DDR4/3800 +1.0% 7 tests @ 1080p, 99th percentile

    Interesting CPU bottleneck on Optane/SSD/Hard Disk

    Posted: 23 Apr 2022 11:49 PM PDT

    Granted large files of course transfer at max speed, the expected speed of a large number of ~100kB files is severely below expectations, even comparing to CrystalDiskMark Random 4KQD1 scores.

    I have 2gb/32,000 file ShaderCache folder. File size ranges from 1kb to 200kb.

    Copying onto different storage devices while keeping a close eye on the CPU usage reveals interesting bottlenecks in Windows.

    -- 16MB/s on every media, including Hard Disk -- A single CPU core is maxing.

    OK, so virus scanner is likely holding it back - I disable Windows Defender.

    -- 70MB/s on all media. A single CPU core is still maxing.

    What else is wrong? -- My Optane 900p can do 250MB/s 4K1T

    ​

    The tested media:

    Optane 900p (4k1t random benchmarked to 250 MB/s)

    Samsung T5 SSD (4k1t random benchmarked to 25 MB/s)

    SATA Hard Disk. (4k1t random benchmarked to 0.5 MB/s)

    System: [99000K@5.1GHz](mailto:99000K@5.1GHz), 4000MT/s DDR4@CL16

    ​

    Conclusions I find interesting:

    1. Windows Defender scanning files being opened/written using a single thread causes a huge bottleneck when dealing with lots of small files on modern SSDs. Multi-theaded scanning would have been immensely helpful, but defender only uses a single thread in these operations - wow.
    2. Even when windows Defender is disabled, Windows reading/writing/copying is very primitive. It relies on a single thread to read/write/move data, and does so inefficiently. This was probably OK back in the SATA Hard Disk days when we were limited to 1MB/s on small files, or even early SSD days, but this is woefully outdated and slow in modern multi-core NVMe systems.
    3. Storage benchmarkers usually do a 'real world' small file transfer test when reviewing modern storage. I doubt they realise all their small file benchmarks are being bottlenecked by their Windows/CPU, when inevitably, at the end of every such article, it righteously exclaims "lol, it makes no difference in the real world bro!"
    4. Certainly, Sony realised this and made custom hardware specifically for SSD encoding/decoding on the PS5. MS also realised this to some extent for their new XBox. Unfortunately, Windows only has 'direct storage' sometime down the line which uses the GPU for read/write, so only really useful for games. What is happening with general Windows? Does the enterprise sector use better algorithms? Is this deliberate segmentation by M$ to make companies buy their enterprise 'solutions'?

    ​

    Conclusion:

    I find myself quite shocked at Windows's primitive handling of data read/write/copy operations. It is in woeful need of multithreading, and optimisation. It is no wonder that in 'real world' benchmarks, most reviewers don't see an impact with new storage technologies - well - windows is the bottleneck, and to some extent the CPU/Express interface - not the storage media...

    ​

    EDIT:

    Using a separate multithreaded Copy/Paste tool fixes the issue. My above suspicions were correct - Windows 10 default file handler is horrible.

    2GB 32,000 file quick benchmark:

    ​

    Win10 default:

    Maxes single thread.

    With Defender = 18MB/s

    Without defender = 70MB/s

    ​

    FastCopy (free, multithreaded) -- bad windows 10 integration

    Maxes all 16 threads in both instances, wow!

    With Defender = 160MB/s

    Without Defender = 275MB/s

    ​

    TeraCopy (free, semi-multi-threaded) -- excellent Windows 10 integration, replaces default.

    With defender = 25MB/s -- Maxes single thread

    Without defender = 180MB/s -- Maxes 2.5 threads.

    ​

    On the hunt for best of both worlds alternatives...

    why is no one moving to arm v9 yet? It's already released long ago and supports scalable instructions would nt solve all our problems with arm rt now?

    Posted: 24 Apr 2022 11:53 AM PDT

    Arm v9 offers more scalability and support in the contexts of traditional instruction sets rt? And the security upgrades and next gen graphics are a plus too. Why has this not seen mass market adoption yet? Mac especially has a lot to gain with having arm v9 in M2 rt? So why the slow pace 🤔
