UnverifiedNVIDIA、AMD 和 Intel 的 GPU 顶点缓存容量普遍在 16 至 32 个顶点条目左右76% similar UnverifiedGPU渲染优先看显存容量而非节点数：单帧场景显存占用超过节点单卡显存会直接崩溃或转CPU。大型场景（>24GB显存需求）需选提供48GB或多卡NVLink节点的平台，否则再多节点也无法渲染单帧72% similar Verified以70B参数模型、FP16精度、32层注意力头为例，单条200K长度请求的KV Cache约需80-120GB显存，远超单张A100 GPU的80GB显存上限71% similar UnverifiedConsumer-grade GPUs like the RTX 4090 max out at 24GB of VRAM, making them inadequate for 70B-class models.71% similar Unverified自回归解码在批大小为1时算术强度约等于隐藏层维度（通常4096至16384），而现代GPU峰值算术强度往往超过200，导致解码处于内存带宽受限状态70% similar
