【AI】NVIDIA DGX Spark + Apple Mac Studio = 4x Faster LLM Inference with EXO 1.0
EXO Labs wired a 256GB M3 Ultra Mac Studio up to an NVIDIA DGX Spark and got a 2.8x performance boost serving Llama-3.1 8B (FP16) with an 8,192 token prompt. Their detailed explanation taught me a lot about LLM performance ... EXO noted that the Spark has 100 TFLOPS but only 273GB/s of memory bandwidth, making it a better fit for prefill. The M3 Ultra has 26 TFLOPS but 819GB/s of memory bandwidth, making it ideal for the decode phase.
因为 LLM 的运行逻辑,[英伟达新出的 DGX](# NVIDIA DGX Spark 搭载与 MediaTek 共同设计的 GB10 超级芯片) 和 Mac Studio 形成了奇妙的互补关系,建议直接读原文,很简单好读。
【苹果】The Just Plain M5 Chip Launches in Three Updated Products: 14-Inch MacBook Pro, iPad Pro (Both Sizes), and Some Sort of Headset Thingamajig Called Vision Pro
The new Dual Knit Band ($99 on its own) looks like a hybrid of the more attractive Solo Knit Band (which did not have a strap that went over the top of your head) and the Dual Loop Band (which did have an over-the-head strap, but which looked somewhat orthopedic). It’s a tacit acknowledgement that physical comfort has been a real problem for many people who’ve tried Vision Pro. (Me, personally, I find using it with the Solo Knit Band comfortable for as long as I care to use it — which is typically just 2–3 hours, tops.)
苹果突然(好吧也不太突然,毕竟 Mark Gurman 早就爆料了)发布了 M5 系列新品,对我来说最有兴趣的是新 Vision Pro 的这个头带,等能买了我去买来试试。另外,新的 iPad Pro 因为用了 N1 芯片,也有 Thread 支持了。
【书】父亲的解放日志

出门的路上读完了这本书,不是很长,但是真的很好看,强烈推荐。
其他一些乱七八糟的
- 市场监管总局征求意见:外卖平台应对“无堂食”商家加专属标识 这个监管水平太差了,可以预见到接下来对于什么算堂食也要争议,完全没必要,明厨亮灶就很好了,群众要的是安全卫生,不是堂食。
- 刘慈欣小说《赡养上帝》改编:国产科幻电影《赡养天神》备案立项 上帝改成天神不是很带感,应该叫改成赡养神仙。
- APPLE LAUNCHES NEW ENVIRONMENTAL INITIATIVES…IN EUROPE AND CHINA 在美国现在这个大环境下,苹果还在坚持推进环保,可以说是战略定力很强了
