You can get 128GB @ ~500GB/s now for ~$2k: https://a.co/d/bjoreRm https://a.co/d/bjoreRm It has 8 channels of DDR5-8000.

  Per above, you need 272GB to run Qwen3-Coder (at 4 bit quantization).

  wrong it is approx half bandwith

  AMD says "256-bit LPDDR5x" It might be technically correct to call it 8 channels of LPDDR5 but 256-bits would only be 4 channels of DDR5.

    DDR5 uses 32bit channels as well. A DDR5 DIMM holds two channels accessed separately.

      Thank you for the correction: I didn't realize each DDR5 transaction was only 32 bits.
