上代Habana Gaudi AI训练加速器，可与NVIDIA的Tesla加速器相竞争

We have something very interesting for our readers today. We recently got our hands on some internal documents that confirm Intel is preparing to launch a next-generation AI training accelerator with monstrous capabilities later this year. Dubbed the Habana Gaudi 2 platform, it will take aim at NVIDIA's new datacenter products (launching later this week) for deep learning and aims to provide a higher value (from a TCO perspective) alternative. Keep in mind the documents were dated earlier this year, and the launch window *could* have moved during this time so take that with a grain of salt.
我们今天有一些非常有趣的东西供读者使用。我们最近拿到了一些内部文件，证实英特尔正准备在今年晚些时候推出具有可怕功能的下一代人工智能训练加速器。它被称为Habana Gaudi 2平台，它将瞄准NVIDIA用于深度学习的新数据中心产品（本周晚些时候推出），旨在提供更高价值（从TCO的角度来看）替代方案。请记住，这些文件的日期是今年早些时候的，发射窗口可能在这段时间内已经移动，所以要谨慎对待。

Intel gets ready to 'play offense' with Habana Gaudi 2 deep learning processor, launching in May 2022
英特尔准备使用Habana Gaudi 2深度学习处理器对市场发起"进攻"，该处理器于2022年5月推出
Intel's Habana offerings are split into two categories: AI training and AI inference. The Gaudi platform is the AI training platform and Goya is the AI inference platform. The Gaudi 2 chip will succeed the older Gaudi chips offered by Intel. While the documentation we acquired only talked about a Gaudi 2 chip, [caution: editorial speculation] it is possible that there is a Goya 2 chip in the works as well [/editorial speculation] - since AI training and inference is usually a combo offering by most vendors. Vendors can utilize Intel's Gaudi platform using the Amazon AWS EC2DL1 instance, where it already offers 40% better performance per dollar than NVIDIA-based instances.
英特尔的Habana产品分为两类：人工智能训练和人工智能推理。Gaudi平台是AI训练平台，Goya是AI推理平台。Gaudi 2芯片将接替英特尔提供的较旧的Gaudi芯片。虽然我们获得的文档只谈到了Gaudi2芯片，但编辑推测也可能有一个Goya 2芯片在开发中 - 因为AI训练和推理通常是大多数供应商提供的组合产品。供应商可以使用 Amazon AWS EC2DL1 实例利用英特尔Gaudi平台，在该实例中，它的每美元性能已经比基于 NVIDIA 的实例高出 40%。

We also have the first-ever picture of the Intel HL 2080 AI chip based on the Gaudi 2 platform:
我们还有基于Gaudi 2平台的英特尔HL 2080 AI芯片的首张图片：


While we did not receive any additional information on the Gaudi 2 HL 2080 chip, we can see that ith as 6 HBM dies. If these are of the HBM2 type, this is a total of 48 GB memory onboard. If it is the HBM3 type, then the sky is the limit and it could be 96 GB (or more). We can also see the soldering pads for a total of 24 VRMs for what appears to be a 12+12 phase design. This is roughly 50% more power than the older Habana chip which had a 8+8 design for a total of 16 VRMs. Assuming these are standard HBM sized chips, it also looks like Intel has increased the die size by 50% over the last generation of Gaudi processors. I am not going to do a die-size estimation here and will leave that to my colleagues to inevitably do.
虽然我们没有收到有关Gaudi 2 HL 2080芯片的任何其他信息，但我们可以看到6 HBM模具。如果这些是 HBM2 类型，则板载内存总计为 48 GB。如果是 HBM3 类型，则天空是限制，可能是 96 GB（或更多）。我们还可以看到总共24个VRM的焊盘，看起来是12 + 12相设计。这比旧的Habana芯片高出大约50%的功率，后者采用8 + 8设计，总共16个VRM.假设这些是标准的HBM尺寸芯片，看起来英特尔的芯片尺寸比上一代高迪处理器增加了50%。我不打算在这里做一个模具大小的估计，并将把它留给我的同事们以后去做。

To get a good idea of the rough transistor count increase, however, we also need to know the process the chip is built on. We know that the Intel Gaudi 2 HL 2080 chip is built on 'a' 7nm process based on this interview by Eitan Medina, COO of Habana Labs. Unfortunately, this doesn't really help us much because 7nm could be referring to the N7 process on TSMC, Intel 7 (formerly Intel 10nm), or Intel 4 (formerly Intel 7nm and the least likely). The original Habana Gaudi processors were built on the 16nm TSMC process which makes it more likely for this chip to be on N7 or Intel 7. Whatever the case is, considering the Gaudi 2 platform is clearly on a far smaller node than 16nm (which in itself gives a density increase of roughly 50%), and combined with the die size increase, we are looking at an absolute beast of a processor which should easily go toe to toe with NVIDIA's upcoming Hopper datacenter GPU - in terms of performance per dollar - and maybe even in terms of absolute performance.
然而，为了更好地了解粗糙的晶体管数量增加，我们还需要知道芯片构建的过程。我们知道，英特尔Gaudi 2 HL 2080芯片是基于哈瓦那实验室首席运营官Eitan Medina的采访，建立在"一个"7nm工艺上。不幸的是，这并没有真正帮助我们，因为7nm可能指的是台积电的N7，Intel 7（以前称为Intel 10nm）或Intel 4（以前称为Intel 7nm，最不可能）这三种工艺中的一个。最初的Habana Gaudi处理器采用16nm TSMC工艺，这使得该芯片更有可能在N7或Intel 7上。无论如何，考虑到Gaudi 2平台显然位于比16nm小得多的节点上（这本身就使密度增加了大约50%），并且结合芯片尺寸的增加，我们正在研究一个绝对的怪兽级处理器，它应该很容易与NVIDIA即将推出的Hopper数据中心GPU并驾齐驱 - 就每美元的性能而言 - 甚至可能在绝对性能方面。

Intel's CEO Pat Gelsinger has previously hinted at a "very aggressive path" for its Habana AI arm:
英特尔首席执行官帕特·格尔辛格（Pat Gelsinger）此前曾暗示其Habana人工智能部门将走上一条"非常激进的道路"：

‘We are playing offense, not defense’..
我们在踢的是进攻，而不是防守。

We also have, with our Habana product line [a specialized A.I. chipmaker Intel bought in 2019], unquestionably laid out a very aggressive path and our cloud partnership with [hotlink]Amazon[/hotlink] is a great demonstration of that. So clearly, I'd say the idea of CPUs is Intel's provenance. We're now building A.I. into that and we expect this to be an area where we are on the offense, not the defense going forward.
无疑，我们还凭借Habana产品线（英特尔在2019年收购的一家专业人工智能芯片制造商）开辟了一条非常积极的道路，我们与Amazon的云合作伙伴关系就是一个很好的证明。所以很明显，我会说CPU的想法是英特尔的出处。我们现在正在将人工智能建设进去，我们希望这是一个我们在进攻的领域，而不是防守领域。

Since being acquired by Intel, Habana Labs would have had a lot more resources to play with and it looks like the company is getting ready to get serious about DL/ML applications. Intel finally has a very real product roadmap that could fend off - and even take marketshare from NVIDIA.
自从被英特尔收购以来，Habana实验室将有更多的资源可以利用，看起来该公司正准备认真对待DL / ML应用程序。英特尔终于有了一个非常真实的产品路线图，可以守住 - 甚至从NVIDIA手中夺取市场份额。
