MI300系列后续产品将在2025年提升显存容量的回应。又一款AI核弹既然都是Blackwell架构没有跨代,B300的算力提高来自哪里呢?根据这次爆料,主要有三部分:工艺节点,与B200使用同样的台积电4NP,但是全新流片增加功率,GB300和B300

NVL72“计算单元”为单位考虑时,它使72个GPU能够以极低的延迟处理相同的问题,并共享显存。在此基础上从GB200升级到GB300,还可以带来许多好处:每个思维链的延迟更低实现更长的思维链降低推理成本处理同一问题时,可以搜索更多样本,最终提高模型能力为了解释这些提升,SemiAnalysis举了个更为直观的例子。下图是在不同批处理大小下,使用H100和H200两种GPU处理长序列时,Llama 3.1 405B在FP8精度下的处理速度。输入设置为1000个token、输出19000个token,由此模拟OpenAI o1和o3模型中的思维链。从H100升级到H200,有两个显著改进。一是在所有可比较的batch size中,H200的内存带宽更大(H200 4.8TB/s,H100 3.35TB/s),从而使得处理效率普遍提高了43%。二是H200可运行更高的batch

辉瑞将与监管机构讨论数据和潜在的监管提交,这是该资产的潜在重大更新,因为它将允许Adcetris从较小的市场(如典型何杰金氏淋巴瘤)扩展。 仅在美国,每年就有超过25,000例DLBCL确诊病例,40%的患者在一线治疗后复发或难治性疾病。在看到数据以及Adcetris联合来那度胺和利妥昔单抗与安慰剂相比的表现之前,估计每年的最高收入贡献为数亿美元。 对于辉瑞这样规模的公司来说,这只是九牛一毛,但这是一个好消息,代表着朝着正确方向迈出的一步,并且证明了Seagen的高价格是合理的。 肿瘤学创新日

毛利率高于预期美东时间2月22日周三美股盘后,英伟达公布,在截至公历2023年1月29日的2023财年第四财季(下称四季度),营业收入和每股收益(EPS)都高于华尔街预期:四季度营业收入60.5亿美元,同比下降21%,环比前一季度增长2%,处于公司指引区间60亿美元的正负浮动2%水平,分析师预期为60.2亿美元,此前一个季度、即第三财季同比下降17%;全财年营收269.7亿美元,略高于2022财年的269.1亿美元。四季度非GAAP口径下调整后EPS为0.88美元,同比下降33%,环比增长52%,分析师预期为0.80美元,第三财季同比下降50%;全财年EPS为3.34美元,较2022财年下降25%。四季度非GAAP口径下调整后毛利率为66.1%,符合公司指引66%(上下浮动50个基点),同比2022财年四季度的67%回落0.9个百分点,环比第三财季的56.1%增长10个百分点,分析师预期毛利率为65.8%;全财年毛利率59.2%,较2022财年下降7.6个百分点。四季度调整后营业利润22.2亿美元,同比下降40%,仍高于分析师预期的21.6亿美元;全财年营业利润90.4亿美元,较2022财年下降29%。四季度自由现金流17.4亿美元,同比下降37%,低于分析师预期的21.6亿美元。四季度研发费用19.5亿美元,同比增长33%,调整后营业费用17.8亿美元,同比增长23%,均持平分析师预期。英伟达同时公布,四季度通过派息和股票回购回馈股东11.5亿美元,全财年合计回馈104.4亿美元。四季度数据中心收入同比增长超预期放缓 游戏收入环比猛增分业务看,四季度英伟达的两大核心业务——数据中心和游戏的收入分别保持了各自的增长和下降势头,但数据中心增长放缓程度超过市场预期,游戏的收入同比下降程度不及预期,环比还有10%的增长。全年数据中心总收入两位数猛增,游戏收入剧减近30%。四季度数据中心的收入为36.2亿美元,同比增长11%,第三财季同比增长31%,分析师预期38.6亿美元。数据中心全财年的营收达到创纪录的150.1亿美元,较2022财年增长41%。四季度游戏的收入为18.3亿美元,同比下降46%,环比增长16%,第三财季同比下降50%,分析师预期16亿美元。游戏业务全财年营收90.7亿美元,较2022财年下降27%。一季度整个营收指引区间高于市场预期业绩指引方面,英伟达预计,2024财年第一财季,营收为65亿美元,正负浮动2%,相当于在63.7亿到66.3亿美元之间,整个指导区间都高于市场预期的63.5亿美元。英伟达还预计,第一财季GAAP和非GAAP口径下的毛利率为64.1%到66.5%,各自上下浮动50个基点;GAAP和非GAAP口径下的营业费用料将分别为25.3亿和17.8亿美元。赶ChatGPT风潮 英伟达AI云服务可帮助企业定制AI模型最近ChatGPT掀起新的一波人工智能(AI)热潮,让之前就在开拓AI计算市场的英伟达也成为受益者。发布财报的同时,英伟达本周三介绍了旗下AI云服务产品。英伟达表示,公司在和云服务巨头合作,提供人工智能即服务(AIaaS),让企业客户能利用英伟达的全球领先AI平台。客户将能够将能使用英伟达AI的每一层作为云服务使用,包括AI超级计算机、GPU加速的软件库、预训练的生成式AI模型。通过自己的浏览器,企业客户将能够通过英伟达DGX Cloud使用英伟达DGX AI超级计算机,英伟达DGX Cloud 已经在甲骨文的Oracle Cloud Infrastructure上提供,微软云Azure、谷歌云平台等和其他云预计很快也会提供。在 AI平台的软件层,客户将能够访问英伟达AI Enterprise,训练和部署大型语言模型或其他AI工作。在 AI模型即服务层,英伟达将为希望构建专有生成式AI模型和服务的企业客户提供,可定制的NeMo框架和BioNeMo框架AI模型。","news_type":1,"symbols_score_info":{}},"isVote":1,"tweetType":1,"viewCount":2110,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"CN","totalScore":0}],"hots":[{"id":305905108984000,"gmtCreate":1715718521179,"gmtModify":1715718522776,"author":{"id":"3569893253045018","authorId":"3569893253045018","name":"Burt

left;\">根据SemiAnalysis爆料,从第三季度开始,<strong>许多AI巨头已经将订单从B200转移到了B300</strong>(只有微软还在第四季度继续购买了部分B200)。</p><p style=\"text-align: left;\">有不少网友感叹,更新速度实在太快了!</p><p style=\"text-align: left;\">既是解决了此前传闻中B200因设计缺陷被迫推迟的问题,又是对隔壁AMD MI300系列后续产品将在2025年提升显存容量的回应。</p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/0dc1722b58eb13468099c2bac62e47ce\" alt=\"\" title=\"\" tg-width=\"1064\" tg-height=\"456\"/></p><h2 id=\"id_3472682946\" style=\"text-align: left;\">又一款AI核弹</h2><p style=\"text-align: left;\">既然都是Blackwell架构没有跨代,B300的算力提高来自哪里呢?</p><p style=\"text-align: left;\">根据这次爆料,主要有三部分:</p><ul style=\"list-style-type: square;\"><li><p><strong>工艺节点,</strong>与B200使用同样的台积电4NP,但是全新流片</p></li><li><p><strong>增加功率,</strong>GB300和B300 HGX的TDP分别达到1.4KW、1.2KW,相比之下B200系列分别提高0.2KW</p></li><li><p><strong>架构微创新,</strong>例如在CPU和GPU之间动态分配功率</p></li></ul><p style=\"text-align: left;\">除了更高FLOPS之外,B300系列的显存也做了升级:</p><ul style=\"list-style-type: square;\"><li><p>从8层堆叠的<strong>HBM3E</strong>升级到12层(12-Hi HBM3E)</p></li><li><p><strong>显存容量</strong>从192GB升级到288GB</p></li><li><p><strong>显存带宽</strong>保持不变,仍为8TB/s</p></li></ul><p style=\"text-align: left;\">此外产品交付层面还有一个大变化:</p><p style=\"text-align: left;\">GB200系列提供整个<strong>Bianca Board</strong>,也就包括两颗GPU、一颗CPU、CPU的内存等所有组件都集成在一块PCB版上。</p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/262abf69a417b8ad4b4fe50f47dc1345\" alt=\"△GB200概念图\" title=\"△GB200概念图\" tg-width=\"1080\" tg-height=\"608\"/><span>△GB200概念图</span></p><p style=\"text-align: left;\">GB300系列将只提供<strong>参考板</strong>(Reference Board),包括两颗B300 GPU、一颗Grace CPU、HMC(Hybrid Memory Cube),<strong>LPCAMM内存模块等组件将由客户自行采购</strong>。</p><p style=\"text-align: left;\">这给供应链上的OEM和ODM制造商带来了新的机会。</p><h2 id=\"id_1947192978\" style=\"text-align: left;\">为推理大模型打造</h2><p style=\"text-align: left;\">显存的升级对OpenAI o1/o3一类的推理大模型至关重要,因为<strong>推理思维链长度会增加KVCache</strong>,影响batch size和延迟。</p><p style=\"text-align: left;\">以一个GB300 NVL72“计算单元”为单位考虑时,<strong>它使72个GPU能够以极低的延迟处理相同的问题,并共享显存</strong>。</p><p style=\"text-align: left;\">在此基础上从GB200升级到GB300,还可以带来许多好处:</p><ul style=\"list-style-type: square;\"><li><p>每个思维链的延迟更低</p></li><li><p>实现更长的思维链</p></li><li><p>降低推理成本</p></li><li><p>处理同一问题时,可以搜索更多样本,最终提高模型能力</p></li></ul><p class=\"t-img-caption\"><img

style=\"text-align: left;\">下图是在不同批处理大小下,使用H100和H200两种GPU处理长序列时,Llama 3.1 405B在FP8精度下的处理速度。</p><p style=\"text-align: left;\">输入设置为1000个token、输出19000个token,由此模拟OpenAI o1和o3模型中的思维链。</p><p

left;\">从H100升级到H200,有两个显著改进。</p><p style=\"text-align: left;\">一是在所有可比较的batch size中,H200的内存带宽更大(H200 4.8TB/s,H100 3.35TB/s),从而使得处理效率普遍提高了43%。</p><p style=\"text-align: left;\">二是H200可运行更高的batch size,这使得其每秒可以生成的token数量增加了3倍,相应地,成本也减少了约3倍。</p><p style=\"text-align: left;\">内存增加所带来的效益远不止表面上的这些。</p><p style=\"text-align: left;\">众所周知,推理模型响应时间一般更长,显著缩短推理时间可以提高用户体验和使用频率。</p><p style=\"text-align: left;\">而且内存升级实现3倍性能提升,成本减少3倍,这一提升速度也远超摩尔定律。</p><p style=\"text-align: left;\">除此之外,SemiAnalysis还分析观察到,能力更强和具有明显差异化的模型能收取更高的溢价——</p><p style=\"text-align: left;\">前沿模型毛利率超70%,而还在与开源模型竞争的次一级模型毛利率不足20%。</p><p class=\"t-img-caption\"><img src=\"https://static.tigerbbs.com/971b41b1bd146a1ffc0f841ce14c5f53\" alt=\"\" title=\"\" tg-width=\"232\"

AI绘图包含72块GB300的“新一代计算单元”GB300 NVL72,更是被评价为“能让OpenAI o1/o3推理大模型的思维链长度,在高batch size下达到10万tokens的唯一方案”。这与今年3月份“AI春晚”发布的B200系列只隔了几个月。根据SemiAnalysis爆料,从第三季度开始,许多AI巨头已经将订单从B200转移到了B300(只有微软还在第四季度继续购买了部分B200)。有不少网友感叹,更新速度实在太快了!既是解决了此前传闻中B200因设计缺陷被迫推迟的问题,又是对隔壁AMD MI300系列后续产品将在2025年提升显存容量的回应。又一款AI核弹既然都是Blackwell架构没有跨代,B300的算力提高来自哪里呢?根据这次爆料,主要有三部分:工艺节点,与B200使用同样的台积电4NP,但是全新流片增加功率,GB300和B300 HGX的TDP分别达到1.4KW、1.2KW,相比之下B200系列分别提高0.2KW架构微创新,例如在CPU和GPU之间动态分配功率除了更高FLOPS之外,B300系列的显存也做了升级:从8层堆叠的HBM3E升级到12层(12-Hi HBM3E)显存容量从192GB升级到288GB显存带宽保持不变,仍为8TB/s此外产品交付层面还有一个大变化:GB200系列提供整个Bianca Board,也就包括两颗GPU、一颗CPU、CPU的内存等所有组件都集成在一块PCB版上。△GB200概念图GB300系列将只提供参考板(Reference Board),包括两颗B300 GPU、一颗Grace CPU、HMC(Hybrid Memory Cube),LPCAMM内存模块等组件将由客户自行采购。这给供应链上的OEM和ODM制造商带来了新的机会。为推理大模型打造显存的升级对OpenAI o1/o3一类的推理大模型至关重要,因为推理思维链长度会增加KVCache,影响batch size和延迟。以一个GB300 NVL72“计算单元”为单位考虑时,它使72个GPU能够以极低的延迟处理相同的问题,并共享显存。在此基础上从GB200升级到GB300,还可以带来许多好处:每个思维链的延迟更低实现更长的思维链降低推理成本处理同一问题时,可以搜索更多样本,最终提高模型能力为了解释这些提升,SemiAnalysis举了个更为直观的例子。下图是在不同批处理大小下,使用H100和H200两种GPU处理长序列时,Llama 3.1 405B在FP8精度下的处理速度。输入设置为1000个token、输出19000个token,由此模拟OpenAI o1和o3模型中的思维链。从H100升级到H200,有两个显著改进。一是在所有可比较的batch size中,H200的内存带宽更大(H200 4.8TB/s,H100 3.35TB/s),从而使得处理效率普遍提高了43%。二是H200可运行更高的batch size,这使得其每秒可以生成的token数量增加了3倍,相应地,成本也减少了约3倍。内存增加所带来的效益远不止表面上的这些。众所周知,推理模型响应时间一般更长,显著缩短推理时间可以提高用户体验和使用频率。而且内存升级实现3倍性能提升,成本减少3倍,这一提升速度也远超摩尔定律。除此之外,SemiAnalysis还分析观察到,能力更强和具有明显差异化的模型能收取更高的溢价——前沿模型毛利率超70%,而还在与开源模型竞争的次一级模型毛利率不足20%。当然,英伟达并不是唯一一家能增加内存的芯片公司,但奈何英伟达还有杀手锏NVLink。One More Thing英伟达消费级显卡方面,RTX5090的PCB板也首次曝光了~就在昨天,一张RTX 5090 PCB照片在网上疯转。特点就是超超超大号。结合此前爆料称5090有可能会配备32GB大显存,有望支持8K超高清游戏,实现60fps的流畅游戏体验。网友们直接坐不住。关于5090的发布时间,大伙儿猜测大概会是1月6日老黄CES演讲的时候。","news_type":1,"symbols_score_info":{"NVDA":1.1}},"isVote":1,"tweetType":1,"viewCount":1325,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"CN","totalScore":0},{"id":385044343501312,"gmtCreate":1735044912132,"gmtModify":1735044913996,"author":{"id":"3569893253045018","authorId":"3569893253045018","name":"Burt
