HBM

Also known as: HBM2e, HBM3, HBM3e, High Bandwidth Memory

High Bandwidth Memory, stacked next to the chip on datacenter GPUs (HBM2e, HBM3, HBM3e). Several times faster than the GDDR memory on consumer and workstation cards.

GPUs with HBM, best value first

VRAMThe GPU's own memory. The model weights, activations and KV cache must fit in it (or be split across GPUs), so VRAM often decides which GPU you can use at all.
Memory bandwidthHow fast the GPU reads its memory, in GB/s or TB/s. Generating LLM tokens is usually limited by bandwidth rather than FLOPS, which is why PetaPrice can rank GPUs by bandwidth per dollar.

Memory

KV cacheMemory an LLM keeps for every token in its context during inference. Long contexts and many parallel requests need a lot of it, on top of the model weights.
