    Credo 也将携 SerDes 参加 ;) (引用推文:对 $AAOI 非常看好。3.2T 短期内不会成为主流,但一旦落地,$AAOI 将是占据战略位置的美国制造商。此外 800G 和 1.6T 的爬坡已在进行,将在短期至中期带动营收增长。)

    So bullish for $AAOI. 3.2T isn’t going to be hitting the main stage for the time being, but when it does, $AAOI will be the US-based manufacturer holding a strategic position. Not to mention the already ongoing 800G and 1.6T rampup that is going to lead to a revenue rampup in the short- to medium-term.

    马斯克称 Tesla AI5 芯片内存减半至 72GB LP5,AI6 降至 144GB LP6,以获得足够产量支持 Optimus 生产并大幅降低成本。他认为这对 Optimus 性能影响可忽略,因为内存带宽比总容量更是瓶颈,且带宽保持不变。SemiAnalysis 的 Dylan Patel 转发并附上其关于 4-Hi HBM 的文章链接。

    We cut our RAM in half for the Tesla AI5 chip (now 72GB of LP5) and 1/3 for AI6 (now 144GB of LP6). This was the only way to get enough volume for Optimus production and greatly reduces cost. As it turns out, we think this will have a negligible effect on Optimus performance, as memory bandwidth is a bigger limiting factor than total memory storage (bandwidth was held constant).

    SemiAnalysis 的 Dylan Patel 发推称 Rubin HBM 降规格(Despec)等于 Nvidia 减料,并引用一篇讽刺文:GB200 NVL72 约 400 万美元、GB300 约 500 万美元(重约 1580 kg),Vera Rubin NVL72 已被报至最高 880 万美元,机柜重量受数据中心地板承重限制而价格不受限,$/kg 每代约 1.75 倍增长,外推 2030 年与可卡因批发价出现交叉。内容为戏谑观点而非测算结论。

    Fentanyl Grade Compute: Why a GB300 Rack Will Out-Price Blow by Weight in 2030 A GB300 NVL72 weighs roughly 1,580 kg fully populated and recent purchase orders put it at $5M per rack. That is $3,165/kg. Strip out the 1.5 tons of busbar, manifold and coolant and the GPU packages alone are well into gold territory, but we're pricing the rack, because that's what you actually take delivery of. Where that sits on the illicit commodity curve today ($/kg): $2,400 Cannabis flower $3,165 GB300 NVL72 $3,500 Fentanyl $28,000 Cocaine $65,000 Heroin $138,000 Gold So today NVIDIA ships a product that is denser in value than weed, roughly fentanyl-grade, and still an order of magnitude short of cocaine. For now... GB200 NVL72 was $4M, GB300 is ~$5M, and Vera Rubin NVL72 is already quoted at up to $8.8M at essentially the same rack mass. Rack weight is constrained by the datacenter floor loading; rack price is constrained by nothing. That's ~1.75x $/kg per generation with HBM, CoWoS and power all supply-limited through the decade. Cocaine: Colombia's new president has pledged a hard-line security crackdown with $1B in US aid behind it Every prior crackdown has consolidated the industry into fewer, better-capitalized operators with better logistics and higher yields per hectare. Consolidation is deflationary. We model US wholesale drifting from ~$28k/kg toward ~$12k/kg by 2030 as the supply chain professionalizes. **Crossover: 2030.** Our extrapolated NVL72-class rack hits ~$17k/kg while wholesale cocaine falls to ~$12k/kg. At that point the rational cartel pivots to smuggling racks, except a rack has a fixed 500+ kW power draw, a 3,300 lb forklift requirement and an export-control regime that is actually enforced. Cocaine has none of these problems, which is why it will remain the superior product for anyone without a substation. Key risks to the thesis: US retail coke is still ~$60–200/g, i.e. $60k–200k/kg so the crossover only holds at wholesale. Retail compute (H100 hour on a neocloud) is also marked up, so we consider this an apples-to-apples wholesale comparison. Full model available to Coke Research subscribers.
