@Vengineer

人生で5000本以上の映画を観ました。そして、今は妄想中です。 映画/書籍(スティーブン・キング)、音楽、で暇を潰しています。 Verilator/Xilinx関連の薄い本をBOOTH ( https://t.co/el3GU4et55 ) にてダウンロード販売しています。

NVIDIA Feynman は、下記の2点の特徴から - 3D Die-Stacking - メモリ: カスタムHBM 2021年の論文 「GPU Domain Specialization via Composable On-Package Architecture」 の中の Domain-Specialized COPA-GPU for DL の実現か? 長かったね。。。

According to a calculation by a Korean journalist estimating how much revenue Samsung Foundry could generate from Groq3 LPU production: NVIDIA has reportedly asked Samsung Foundry to produce around 500,000 LPU 3 chips to start with. That is more than double the originally planned production volume. First, each Groq server introduced by CEO Jensen Huang contains 8 LPUs. When 32 of those servers are combined, they form one rack. That means each rack contains 256 LPUs. One complete Vera Rubin platform contains 5 racks. So each platform would contain 1,280 LPUs. On a simple calculation, if all produced chips were turned into racks, that would imply about 1,950 LPU racks, enough for roughly 390 Vera Rubin platform sets. Looking at the LPU wafer shown in the commemorative photo taken a few days ago at the GTC exhibition featuring CEO Jensen Huang and Han Jin-man, president of Samsung Electronics’ Foundry Business, it appears that around 65 properly shaped LPU dies can be printed on a single wafer. To produce 500,000 LPUs, 7,692 wafers would be required if each wafer yields 65 chips and the yield rate is 100%. However, considering that Samsung’s current 4nm yield is estimated to be around 50–70%, it is possible to infer that more than 15,000 wafers annually would be needed, which is broadly consistent with recent media reports. According to what the journalist heard, the wafer price for Samsung’s 4nm process is at least around $11,000 per wafer. Assuming a possible price increase and using roughly $13,000 per wafer, that would imply about $195 million in revenue, or roughly KRW 300 billion, from LPU production. Given that Samsung Foundry’s annual revenue is known to be around KRW 20 trillion, this would still amount to a very small contribution to total sales.

Kyberって、Compute TrayのBMCって、BlueField-4 についているものだけなのかな? 全体の真ん中に、BMCが1つあるっぽいけど。 これ、右から、mini DP, USB, RJ45、その隣の4個は何のコネクタかな?

Grok さんに聞いたら、 Samsung 4nm (SF4X)で、25mm x 32mm では、 $250 - $300 ぐらいのようです。
