    Why are there no 1.5 GB GDDR6 chips?

    Posted: 05 Jan 2021 03:02 AM PST

    Ok here's a problem in de GPU industry:

    GPUs have a memory interface width. For the GDDR family, 128-bit, 192-bit, 256-bit and 384-bit are the most common (at least for fully functional GPU dies). A higher-end GPU has a wider memory bus to provide more bandwidth, and sometimes more capacity.

    Now here's the problem: GDDR6 chips have a 32-bit bus, and only come in 1 or 2 GB capacities (see Samsung and Micron catalogs). This means only the following capacities are possible for the most common bus widths:

    1 GB chips 2 GB chips
    128-bit 4 GB 8 GB
    192-bit 6 GB 12 GB
    256-bit 8 GB 16 GB
    384-bit 12 GB 24 GB

    Now, you can partially disable a section of the memory bus to differentiate cards from the same GPU die, for example we saw the RTX 2080 Ti with 11 GB and the RTX Titan with 12 GB from the same TU102 die. The first one had just one chip less, using only a 352-bit bus.

    But this solves not everything. Take the RTX 3060 Ti and 3070. Both use the GA104 die with a 256-bit bus and 8 GB memory. Now the RTX 3060 is rumored, using GA106 and a 192-bit bus, and has to choose between 6 and 12 GB memory configurations. Neither are ideal. We also saw it with the GTX 1050 Ti with 4 GB (128-bit bus) and the GTX 1060 with both 3GB and 6 GB (192-bit bus).

    So my question is quite simple: Is there any technical limitation to produce 32-bit 1.5 GB GDDR6 dies. Or is it not economically feasible?

    Because if we introduce a middle-tier 1.5 GB chip, we can solve a lot of problems in current line-up. These are the configurations:

    1 GB chips 1.5 GB chips 2 GB chips
    128-bit 4 GB 6 GB 8 GB
    192-bit 6 GB 9 GB 12 GB
    256-bit 8 GB 12 GB 16 GB
    384-bit 12 GB 18 GB 24 GB

    The RTX 30-line could have looked like this:

    • RTX 3050: 4 GB (128-bit)
    • RTX 3050 Ti: 6 GB (128-bit)
    • RTX 3060: 9 GB (192-bit)
    • RTX 3060 Ti: 12 GB (192-bit)
    • RTX 3070: 12 GB (256-bit)
    • RTX 3070 Ti: 16 GB (256-bit)
    • RTX 3080: 18 GB (384-bit)
    • RTX 3090: 24 GB (384-bit)

    Each higher-end card now has either more bandwidth or more memory or both, but never any less memory. Also the regular and Ti version are based on the same die, as it should be. And if you partially disable the memory bus you can create even more options!

    For AMD the same case could be made, the whole RX 6000 line currently has the same 16 GB memory, which is a bit strange.

    So what's holding 1.5 GB chips back? And could there ever be 3 GB chips instead of jumping straight to 4 GB?

    Why is every phone manufacturer jumping on the Big-little train?

    Posted: 05 Jan 2021 07:16 PM PST

    Looking at the current top-end 'Snapdragon 888' & 'Exynos 1080', both fill half the die with antiquated Cortex-A55, under the marketing label "Low power cores".

    Surely phones would benefit greatly in performance and power consumption running chips that were purely high-end 5 nm silicon, just undervolted and underclocked when there wasn't a need for so-called "High power cores".

    Is this all down to cost-cutting measures? Even if that's the case, wouldn't a quad-core Cortex-A78 or Cortex-X1, that clocked dynamically to serve both high and low power needs, make much more sense and be much cheaper? What's the benefit of shipping tons of Cortex-A55 in $1000 phones?
