    True, I was surprised to see 16 PCIE lanes.

  • Kronos1996 replied to the thread Discussion RDNA4 + CDNA3 Architectures Thread.

    So GB206 is about 10% smaller vs Navi 44 while being slightly more efficient and having better RT. All else being a wash. I guess Nvidia...

  • Kronos1996 replied to the thread Discussion RDNA 5 / UDNA (CDNA Next) speculation.

    GCN had terrible PPA in later iterations which had knock-on effects for efficiency of course. IIRC The memory subsystem was also pretty...

  • Kronos1996 replied to the thread Discussion RDNA 5 / UDNA (CDNA Next) speculation.

    You’ll have to elaborate on that for me. My understanding is that they’re driving to a unified modular CU and ISA. Then just insert...

  • Kronos1996 replied to the thread Discussion RDNA 5 / UDNA (CDNA Next) speculation.

    This implies it’s built on the RDNA 4 ISA? That would be sooner than expected, I figured RDNA 5 at the earliest. They’ve been adding...

  • Kronos1996 replied to the thread Question Zen 6 Speculation Thread.

    Yup that’s always been the trade-off between speed and efficiency. In very basic terms, the closer transisters are together, the shorter...

  • Kronos1996 replied to the thread Question Zen 6 Speculation Thread.

    Why wouldn’t they? Silicon cost isn’t an issue for a ~70mm2 die and 2nm shouldn’t cost much more than N3P while offering bigger...

  • Kronos1996 replied to the thread Question Zen 6 Speculation Thread.

    Agreed, IPC won’t be the focus but I still expect above average single-core gains. Zen 4 was a very similar situation. Built on Zen 3’s...

    Note that starting with Zen5, the TSVs don't go on the CCD. The CCD is face down on top of the cache chiplet, so no holes need to be...

    Shouldn’t be a need. All of them will be using the same packaging this time, similar to whats in Strix Halo. That’s the only reason Halo...

  • Kronos1996 replied to the thread Discussion AMD SoC Halo series GPU discussion.

    That’s not how it works from what I understand. AMD’s semi-custom group will make anything you want for the right price. One question I...

    CCD? Probably two. - Zen 6 - Zen 6C IOD? Probably four. - Desktop - Server - Medusa (Laptop) - Medusa Halo There’s rumors of two...

    Check out this perf/watt difference. Truly a disaster.

    Look, does Adroc have the bedside manner of a Dingo in a Maternity Ward? Yes but he knows what he’s talking about (most of the time.)

  • Kronos1996 replied to the thread Discussion RDNA 5 / UDNA (CDNA Next) speculation.

    I mean Intel has separate GPU tiles on their mobile SoC’s now. Other issues aside, EMIB seems quite affordable now that it’s at volume...
