NVIDIA RTX A4500 Laptop GPU

英伟达™(NVIDIA®)RTX A4500 笔记本电脑 GPU 或 A4500 Mobile 是一款适用于移动工作站的专业显卡。它基于 GA104 Ampere 芯片,类似于消费级的 消费级GeForce RTX 3070 Ti 笔记本电脑 GPU 相似。.它提供 5,888 个图形内核、46 个 RT 内核、184 个 Tensor 内核以及高达 16 GB 的 GDDR6 显存和 256 位内存总线。它支持 PCIe 4.0,将有 80 瓦到 140 瓦(TGP)的不同型号,具有不同的时钟速度(和性能)。GPU 支持 eDP 1.4b 用于连接内部显示器,支持 DisplayPort 1.4 和 HDMI 2.1 用于外部连接。

虽然没有了 Max-Q 变体(以前用于低功耗变体),但每个 OEM 厂商都可以选择采用 Max-Q 技术(Dynamic Boost、WhisperMode)。

原始性能应与 GeForce RTX 3070 Ti 笔记本电脑相近。这两款 GPU 都非常依赖良好的散热和较高的 TGP 来实现良好的性能。在相似的功耗水平下,RTX A4500 的速度应明显快于旧版的 RTX A4000Quadro RTX 4000.不过,A4500 的台式机版本要快得多。

GA104 芯片提供 6,144 个 FP32 ALU,其中一半还可以执行 INT32 指令(即 3,072 个 INT32 ALU)。有了 Ampere,所有着色器仍可执行 FP32 或 INT32 指令。据 Nvidia 称,芯片上的光线追踪和张量内核也得到了改进。A4400 只使用了 6,144 个 CUDA 内核中的 5,888 个。Ampere 芯片还包括改进的第五代视频编码器(用于 H.264 和 H.265 的 NVENC)和第七代解码器(用于各种格式,现在包括 AV1)。现在包括 AV1)。

GA104 芯片由三星公司以 8nm (8N) 工艺制造,与台积电的 7nm 节点(如 AMD 和专业的 GA100 Ampere 芯片)相比还有差距。
