  1. Iṣoro akọkọ wo ni adirẹsi iranti Bandwidth giga fun awọn accelerators AI?
    • Ṣe iṣiro awọn ohun kohun ti o joko laišišẹ lakoko ti o nduro fun data lati de
    • GPUs ti ngbona lati ina pupọ
    • Nfi awọn faili pamọ patapata nigbati agbara ba wa ni pipa
    • Nsopọ GPU si intanẹẹti
  2. Bawo ni HBM ṣe kọ ni ti ara yatọ si iranti GDDR lasan?
    • O ti wa ni ipamọ lori dirafu lile
    • O akopọ ọpọ DRAM ku ni inaro ati ki o so wọn pẹlu nipasẹ-ohun alumọni vias
    • O nlo awọn kebulu fiber optic inu chirún
    • Ko ni transistors
  3. Kini HBM gbarale nipataki lati ṣaṣeyọri bandiwidi giga rẹ?
    • Awọn iyara aago ti o ga julọ ju eyikeyi iranti miiran lọ
    • Itutu pẹlu omi nitrogen
    • Iparapọ to gaju nipasẹ wiwo ti o gbooro pupọ
    • Compressing gbogbo data si ọkan bit
  4. Kini idi ti a fi gbe awọn akopọ HBM sori interposer silikoni kan lẹgbẹẹ GPU?
    • Lati jẹ ki package wo dara julọ
    • Nitori HBM ko le ṣiṣẹ diẹ ẹ sii ju mita kan lọ
    • Lati gba yiyọ kuro ni irọrun nipasẹ olumulo
    • Lati tọju awọn onirin kukuru, idinku agbara fun bit ati lairi
  5. Fun awọn awoṣe ede nla ni pataki, kilode ti HBM le ṣe pataki bi iṣiro aise?
    • Nitori awọn iwọn awoṣe gbọdọ wa ni ṣiṣan nigbagbogbo, nbeere agbara giga ati bandiwidi
    • Nitori awọn awoṣe ko ṣe iṣiro rara
    • Nitori iṣiro jẹ ọfẹ ṣugbọn iranti jẹ owo-ori
    • Nitori awọn LLM nikan lo Sipiyu
  6. Which HBM generations are part of the progression from HBM2 to currently sampling HBM4 products?
    • HBM2, HBM2E, HBM4E, then HBM3
    • HBM2, HBM2E, HBM3, HBM3E, and HBM4
    • GDDR6, GDDR7, DDR5, and HBM4
    • HBM3E directly followed by HBM1
  7. Why can high HBM bandwidth help an autoregressive language model during token generation?
    • It eliminates the need to store model weights
    • It performs tokenization instead of the GPU
    • It can move model weights and other data to the compute units more quickly
    • It makes every model compute-bound
  8. What is the difference between HBM capacity and HBM bandwidth?
    • They are identical measures of GPU clock speed
    • Capacity measures transfer speed and bandwidth measures data size
    • Neither is related to memory
    • Capacity is how much data can be stored; bandwidth is how quickly data can be transferred
