10 questions from Part 7 of the guide. Score instantly; every explanation links to the chapter that derives the answer.

The four accelerator families the guide designs around are…
merchant GPU, systolic-array TPU, hyperscaler custom XPU, and inference ASICCPU, GPU, FPGA, DSPx86, Arm, RISC-V, MIPSconsumer, workstation, server, mobile
In Chapter 7.6’s illustrative decode case, what does fitting within 186 GB establish?
Clock speed is sufficientDie area determines the queueAbout 180 GB fits, but the 40 ms memory lower bound leaves compute and collectives to testTransistor count guarantees latency
What does Micron’s disclosure of contracted calendar 2026 HBM supply establish?
That packaging is already qualifiedThat memory can be substituted without validationMicron’s 2026 commitments, not an allocation to your rackThat every supplier is sold out
In Chapter 7.10’s illustrative fixed-test case, which recipe clears the 89.0% quality floor and the service gates?
Choose by checkpoint size aloneNVFP4 because its format name guarantees qualityAlways choose the fewest bitsFP8 at 89.4% accuracy
The rack-standard fork the facility is built around is…
locking vs open doorsEIA-310 vs OCP ORV3 vs Open Rack Wide — busbars, power shelves, and service clearances all followany rack fits any hallcolors of the rack
The integration-model ladder (DGX turnkey → HGX-from-OEM → ODM-direct → OCP self-design) trades…
only paint colormargin and control against engineering burden and support responsibilityonly delivery timenothing; they're identical
The software-regime commitment (CUDA / ROCm / XLA / Neuron) determines…
only compile timesnothing portable code can't fixthe color of error messageswhich workloads you can serve competitively and how expensive it is to ever leave — the deepest lock-in in the stack
CoWoS-class advanced packaging matters to operators because…
it creates a package qualification and assembly gate distinct from qualified HBM deliveryit's purely cosmeticit eliminates the need for coolingit changes rack width
On-package power delivery is emerging because…
it reduces software bugsat sub-1 V core rails drawing up to ~2,000 A, a shorter qualified power path can reduce I²R loss; converter placement still needs a rail and thermal budgetregulation requires itcables look untidy
For deployment velocity at scale, structured cabling is bought as…
qualified pre-terminated MPO trunks and modular cassettes where their route, polarity and service plan fitwireless linksfield-terminated fiber, artisanallywhatever the electricians prefer
