    Speculation: is Tim Sweeney's comment about the PS5's SSD about GPU direct storage access?

    Posted: 17 May 2020 08:25 AM PDT

    Tim Sweeney tweeted:

    Those PC numbers are theoretical, and are from drive into kernel memory. From there, it's a slow and circuitous journey through software decompression to GPU driver swizzling into video memory where you can eventually use it. The PS5 path for this is several times more efficient.

    Let's assume for a moment that he's literal and not using hyperbole.

    On PC, to load compressed graphical assets, the GPU goes through the PCI-E bus, through the CPU and with RAM as a buffer, and then accesses data on the SSD. And then the CPU decompresses the assets and they are loaded in VRAM following a reverse path.

    What if instead, you had the GPU directly access the SSD, had a dedicated decompression chip for compressed assets, and then directly loaded those assets into VRAM. Short and direct path, no latency.

    There would be extremely little penalty for swapping assets in and out of VRAM as needed.

    And then he also said:

    And so it's really exciting to be seeing the console market push forward the high-end PC market in this way

    GPUs on PC could have direct storage access too. Nvidia published a blog post on the subject and this illustrates the principles.

    This has become part of Nvidia Magnum IO, a set of API that among other things handles how GPU can directly access storage.

    So, maybe this is the future "enhanced datapath" for graphical assets on PC too?

    By the way, Microsoft calls their API Direct Storage and wrote this about it:

    This newest member of the DirectX family is being introduced with Xbox Series X and we plan to bring it to Windows as well.

    Coincidence?

    This OP was highly speculative, but I would posit that people reducing SSDs on consoles are merely rejoining what PCs had for years are making a mistake, there are/will be fundamental architectural changes with regards to how data is accessed in any platform.

    Laptop 2060 has 40 more FPS in csgo comparing to 2070?

    Posted: 18 May 2020 02:44 AM PDT

    Hi all,

    I'm thinking of buying one of these laptops msi gl75 vs msi gp75

    They have the same cpu, screen size and I have watched jarrods tech review video for both of them.

    Turns out in CSGO the gl75 with 2060 can get 40more FPS than the 2070?!

    How is this possible?

    Of course there are other games he has compared and the 2070 has more fps.

    But since I play csgo mostly, that means there is no point for me to get the 2070 msi gp75 then?

    https://youtu.be/3tALnJzMrjE Msi gp 75 Skip to 3:51 for csgo FPS

    https://youtu.be/n5KuwDjUOzA Msi gl 75 Skip to 4:04 for csgo FPS

    Pls let me know your 2cent

    Thanks

    What are the gold blocks on the newly announced Nvidia Ampere GPU?

    Posted: 17 May 2020 12:24 PM PDT

    Looking at the press images of the new Nvidia Ampere graphics card, I noticed these gold blocks where the VRMs usually are. Are these special self-contained VRMs? Is there any reason these were used as opposed to normal VRMs, and if I want to learn more about them, what should I search for?

    Are AIO CPU coolers unreliable?

    Posted: 17 May 2020 06:55 AM PDT

    My current system is starting to fail, it's nearly 10 years old and I've had the same Noctua CPU cooler running all that time with no issues.

    I have always wanted a AIO, but answering stuff in the techsupport sub a lot, I see a regular pattern of pump failures after 2 years, sometimes less.

    Are the numbers of failures just disproportionate because I'm seeing a lot of failures in the techsupport sub, or are they really only designed to last a few years?

    Why do bits come in groups that are powers of 2, such as 8 and 16, instead of groups such as 10?

    Posted: 17 May 2020 07:13 AM PDT

    Engineering uses 3 significant decimal digits. I ran the calculations on my calculator app, and the equivalent to this precison is 10 bits. Why are processor architectures 8-bit, 16-bit, and beyond?

    Excellent pre-launch summary on 10900K

    Posted: 17 May 2020 08:36 AM PDT

    I just watched this video as an industry insider and just have to say this is spot on. Definitely worth watching for the analysis, if not for the chill. Very impressive frequency at this process node. Very much incremental but still ahead in gaming and other specific cases.
