An interactive, visual deep dive into GPU silicon, high-speed fabrics, and datacenter clusters. Built for cloud engineers, systems architects, DevOps, and developers.
The Master Chef vs 5,000 Line Cooks. Serial latency vs parallel throughput, the 4K pixel race benchmark, and why AI is linear algebra.
Streaming Multiprocessors (SMs), the factory worker with a calculator vs the 4×4 hydraulic stamping press, and the 3.35 TB/s HBM firehose.
The 3 AM CUDA Out of Memory crash, Model Weights static rent, dynamic KV Cache explosion, and the live interactive VRAM budget simulator.
The Prompting Paradox: Prefill Phase (Compute-Bound) vs Decode Phase (Memory-Bandwidth-Bound), streaming 70GB per token, and Continuous Batching.
NVIDIA CUDA moat, Google TPU Systolic Arrays (Bucket-Brigade wave), Intel AMX on existing servers, and the live TCO hardware decision engine.
The $10k/hr AllReduce barrier, East-West all-to-all tidal waves, 4-copy TCP kernel penalties, zero-copy GPUDirect RDMA, and rail-optimized fat-trees.
The $100B protocol war: Hardware credit flow, SHARP in-network compute, RoCEv2 PFC pause storms, deadlocks, and the Ultra Ethernet Consortium.
The 900 GB/s highway: NVSwitch crossbar matrix, 640GB unified memory pooling, and the rack-scale GB200 NVL72 with 5,000 copper cables.
The 405B parameter reality: Tensor Parallelism (Megatron-LM), Pipeline Parallelism (1F1B schedule), and DeepSpeed ZeRO-1/2/3 parameter sharding.
The 100-Megawatt silicon cathedral: GB200 NVL72 130 kW racks, 13.1 Pb/s non-blocking fat-tree, checkpoint storage, and direct-to-chip liquid cooling.
