    "10GB is enough" - nVidia

    I'll never be not-furious over the fact that they charged us for 30GB of RAM and delivered 10, meanwhile low end budget models have more.

    Just for some bonus salt in the wounds I waited for AMD only to get kicked in the nuts by them too and delayed getting my 3080 because of them. I was really hoping to have a 16GB card at the least.

    So the 3060 gets 12Gb while the 3080 is limited to 10? Sounds logical...

    Yeah it makes no sense, seeing even a 3060 Ti is only a 1440p card, no way you're going to need more than 8GB.

    I would be careful with 8gb card even at 1440p. 3060Ultra 12gb sounds better to me.

    It would be a miracle to get one of these at that price

    It uses slower memory, the 3060 is using GDDR6 and the 3080 is using GDDR6X


    GDDR6 vs GDDR6X
    NVIDIA is the first vendor to opt for GDDR6X memory in its RTX 30 series GPUs, at least the higher-end ones. It increases the per-pin bandwidth from 14Gbps to 21Gbps and the overall bandwidth to 1008GB/s, even more than a 3072-bit wide HBM2 stack.

    GDDR6X GDDR6 GDDR5X HBM2
    B/W Per Pin 21 Gbps 14 Gbps 11.4 Gbps 1.7 Gbps
    Chip capacity 1 GB (8 Gb) 1 GB (8 Gb) 1 GB (8 Gb) 4 GB (32 Gb)
    No. Chips/KGSDs 12 12 12 3
    B/W Per Chip/Stack 84 GB/s 56 GB/s 45.6 GB/s 217.6 GB/s
    Bus Width 384-bit 384-bit 352-bit 3072-bit
    Total B/W 1008 GB/s 672 GB/s 548 GB/s 652.8 GB/s
    DRAM Voltage 1.35 V 1.35 V 1.35 V 1.2 V
    Data Rate QDR QDR DDR DDR
    Signaling PAM4 Binary Binary Binary
    [​IMG]
    The secret sauce behind GDDR6X memory is PAM4 encoding. In simple words, it doubles the data transfer per clock compared to GDDR6 which uses NRZ or binary coding.

    [​IMG]
    With NRZ, you had just two states, 0 and 1. PAM4 doubles it to four, 00, 01,10, and 11. Using these four states, you can send four bits of data per cycle (two per edge). The drawback with PAM4 is the high price especially at the higher frequencies of GDD6X. This is the reason why no one has tried to implement it in consumer memory before.

    [​IMG]
    This is one down-side with this. While GDDR6 has a burst length of 16 bytes (BL16), GDDR6X is limited to BL8 or 8 bytes, but because of PAM4 signaling, each of its 16-bit channels will also deliver 32 bytes per operation. Therefore, most of the improvement in bandwidth has come from higher operating frequency on GDDR6X. Keep in mind that GDDR6X is not a JEDEC standard, rather a proprietary solution from Micron.

    That reminds me of Fury X vs 980ti when amd said faster hbm will compensate for having less vram and then it didnt.

    Yeah, 3060 Ultra with 10 or 12 GB is reasonable, but the 3060 with 12, while the Ti has 12 (+NV telling that 10 GB is enough with the 3080....)? No logic in that.

    Well these are just the facts and I highly doubt nvidia would release a 3060 that's faster than a 3080.

    Given that the xx60 are targeting 1080p it doesnt need to be that fast but do they really need 12 gb vram for 1080p....seems that Nvidia are a bit confused.....giving the 60 more ram than the 70....either that or they're taking the pi$$.

    A 12gb card would've been very useful for VR. But this 3060 probably has the same raw performance as a 1080 ti. However, a card with this level of performance is not anymore enough for the newer VR headsets.
