    Hardware Leak Tracker - The Who's Who of Leaks

    Posted: 04 Jun 2021 05:20 PM PDT

    [Link to spreadsheet at the bottom of this post]

    I thought I'd share my own work that I've been doing in determining who is a good leaker and who isn't, based on the claims they've made and whether or not they come true or not.

    It took me many months to compile all the data and I wanted to be able to know without a doubt who are the 'guess-timators' pulling numbers out of the air, who actually have consistent and reliable sources, and who is just following the trends and using their own analysis to try to cut through the weeds.

    While it may seem like it's a very subjective whether someone is making a claim or not, or whether someone it just speculating, or just making discussion, etc, I put together a set of very strict rules as to how I count claims and also how I verify them. The rules are listed in the summary of results tab so you can look at them and see how the data is represented.

    In the end, the idea was to simply score each leaker by the % of the number of claims they got right.

    The data covers all leaks that have been made by each of the known sources, as far back as I could go. For some leakers this data stretches all the way back to before the Zen1 years. For most twitter leakers, this only goes back to 2018 or so.

    I know that there are still some very popular leakers out there that I haven't covered. But honestly, doing only a couple channels was hard enough going through all the videos (but it was fun/cringey sometimes as well). I don't want to go through like 4 or 5 more channels..it's just simply too much time, and, honestly, I hadn't planned on sharing this project except for maybe the results page. But here it is anyway.

    I also hadn't added any well-known forum leakers, as that is a huge mess going through posts that are scattered all over the place. So mainly it's just twitter, Youtube, and some specific websites.

    The last time I updated the sheet for new leaks was sometime in the beginning of Feb 2021, so new leaks since then have not been added. However, I have just gone through all of the leaks that were added before then and verified any that could be verified, so it is an up-to-date account of the leaks, verified against the information that we have from products that have been released up to today.

    The results speak for themselves. You can dig into the data page as well to see specific leaks that have been verified. I should also note that leaks that are behind a paywall have been hidden, but are still counted in the results page.

    I won't be updating the list anymore, so this is the Who's Who as of Feb 2021. Some people have gotten better at leaking, some have gotten worse, some have just remained bad. But I hope everyone can use this to determine who is and isn't dependable when it comes to spilling the beans, and be able to make a decision for themselves whether a leak is likely to be true or not, at least in part, based on who is the one doing the leaking.

    If anyone wants to take this data and make a cool looking spreadsheet or infographic, be my guest.

    So, without further ado, here are the results

    Cheers all.

    Edit: I updated the sheet to also show the claims that haven't been verified yet, updated to Feb 2, 2021. I've added those on a separate sheet.

    Edit2: Anyone can use this data for whatever. It's all good.

    Micron launches 176-layer NAND flash and 1-alpha DRAM chips for the data economy

    If 3D VCache can go 8 layers high, would this scale to L1 and L2? (512KB of L1 and 4MB of L2 per core)?

    Posted: 04 Jun 2021 08:58 PM PDT

    That would be a lot of transistors, a 24 core CPU would have 4.8 billion transistors in the L2 alone and another half a billion or so in L1. Or would there be too much heat?

    [Hardware Unboxed] - AMD Radeon RX 6800M Review, Is Nvidia's Laptop GPU Monopoly Over?

    I think Big Navi was just a proof of concept of AMD's MCM Active Chiplet

    Posted: 04 Jun 2021 07:24 AM PDT

    I was reading through AMD's patent filing for active bridge chiplet with integrated cache when one snippit stuck out to me.

    "an active bridge chiplet 118 communicably couples the GPU chiplets 106 (i.e., GPU chiplets 106-1 through 106-N) to each other. Although three GPU chiplets 106 are shown in FIG. 1, the number of GPU chiplets in the chiplet array 104 is a matter of design choice and varies in other embodiments, such as described in more detail below. In various embodiments, such as discussed below in more detail with respect to FIG. 2, the active bridge chiplet 118 includes an active silicon bridge that serves as a high-bandwidth die-to-die interconnect between GPU chiplet dies. Additionally, the active bridge chiplet 118 operates as a memory crossbar with a shared, unified last level cache (LLC) to provide inter-chiplet communications and to route cross chiplet synchronization signals."

    This sounds a lot like the infinity cache introduced in RDNA2. RDNA2 also happens to effectively be a doubling of RDNA, with an added last level cache. I decided to go look up some block diagrams of the 2 RDNA µarchs and compare. Sure enough, when comparing between both RDNA and RDNA2 (Images courtesy Anandtech reviews of RDNA here and RDNA2 here), RDNA2 looks like 2 RDNA chips mirrored end to end with a last level "infinity cache" connecting them. A more low level block diagram courtesy Techpowerup seems to confirm this.

    Its quite possible that RDNA2 was basically just a tweaked RDNA in order to test out the concept of a last level cache to synchronize multiple GPUs. This would likely explain the negligible difference between RDNA and RDNA2 when compared core to core and clock to clock as in Techspot's clock for clock comparison test. If this is true, with AMD's unveiling of the 3d stacked 5900x that is an actual functional processor that is supposedly going to enter production by the end of this year would mean that they are likely well under way to having a MCM Active bridge GPU on the way. If RDNA2 is any indication, AMD are remarkably close to having linear gains by doubling up cores.

    If anyone happens to have both a 6900xt and a 5700xt, I would be very interested in seeing how the performance stacks up when benchmarked clock for clock.
