在科技领域，由著名计算机工程师 Jim Keller 创立的 Tenstorrent 公司最近宣布推出图形处理单元 (GPU) 的 RISC-V 替代品，名为 Grayskull。该器件提供更简单的编程和扩展功能，特别是处理运行时稀疏和条件计算。它旨在满足人工智能 (AI) 开发的需求，提供 Tensix 核心等各种工具，允许设备之间直接通信，无需通过动态随机存取存储器 (DRAM) 进行路由，从而提高速度和效率。目前提供两种变体：Grayskull e75 和 Grayskull e150，两者均针对不同目的进行了优化 - 前者低调且仅用于推理，而后者则提供更大的吞吐量和更高的功耗（高达 200 瓦）。这些设备提供与流行模型的兼容性，例如用于自然语言处理 (NLP) 的 Bert、用于图像识别 (IR) 的 ResNet、用于语音识别 (SR) 的 Whisper、用于对象检测 (OD) 的 YOLO v5 和用于图像分割的 U-Net（ IMGSEGM）。 Grayskull e75 和 e150 DevKit 的售价分别为 599 美元和 799 美元。在注册接收电子邮件时提交个人数据，即表示访问者确认接受条款和条件以及隐私政策，并确认年满 16 岁。

回答您的问题： - 是的，Grayskull 核心的功能与 Picochip 类似。不过，它们与英特尔和 Picochip 没有直接关系。它们的出现是因为需要设计具有低精度数据类型的高效且可扩展的矩阵处理单元，而不需要过多的计算资源。关于前面提到的定价结构，对于小型企业或个人来说似乎成本过高，但 Tenstorrent 提供了一系列选择，包括内核较少的卡或托管服务，以满足不同的企业规模和能力。最终，定价反映了开发和生产此类尖端硬件和软件基础设施的相关成本。关于 8GB 的削减，考虑到内存资源有限，tenstorrett 开发了能够在内存中进行高效处理的技术和算法，从而减少对外部内存源的需求。但是，根据模型或正在处理的数据的性质和复杂性，建议在扩展处理器容量的同时扩展内存容量。

Tenstorrent, the firm led by legendary chip architect Jim Keller, the mastermind behind AMD's Zen architecture and Tesla's original self-driving chip, has launched its first hardware. Grayskull is a RISC-V alternative to GPUs that is designed to be easier to program and scale, and reportedly excels at handling run-time sparsity and conditional computation.

Off the back of this, Tenstorrent has also unveiled its Grayskull-powered DevKits - the standard Grayskull e75 and the more powerful Grayskull e150. Both are inference-only hardware designed for AI development, and come with TT-Buda and TT-Metalium software. The former is for running models right away, while the latter is for users who want to customize their models or write new ones.

The Santa Clara-based tech firm's milestone launch comes hot on the heels of a partnership with Japan's Leading-edge Semiconductor Technology Center (LSTC). Tenstorrent's RISC-V and Chiplet IP will be used to build a state-of-the-art 2nm AI Accelerator, with the ultimate goal of revolutionizing AI performance in Japan.

The Grayskull e75 model is a low-profile, half-length PCIe Gen 4 board with a single Grayskull processor, operating at 75W. The more advanced e150 model is a standard height, 3/4 length PCIe Gen 4 board containing one Grayskull processor operating at up to 200W, and balancing power and throughput.

Tenstorrent processors comprise a grid of cores known as Tensix Cores and come with network communication hardware so they can talk with one another directly over networks, instead of through DRAM.

The Grayskull DevKits support a wide range of models, including BERT for natural language processing tasks, ResNet for image recognition, Whisper for speech recognition and translation, YOLOv5 for real-time object detection, and U-Net for image segmentation.

The Grayskull e75 and e150 DevKits are available for purchase now at $599 and $799, respectively.
