英特尔披露 Wildcat Lake 处理器：平台 AI 算力最高 40 TOPS，UCIe 多芯片封装_我的网站

A |      8 月 25 日消息，科技媒体 Wccftech 昨日（8 月 24 日）发布博文，报道称英特尔披露了 Wildcat Lake（酷睿 Series 3）系列处理器的相关细节。定位方面，英特尔 Wildcat Lake 主要面向入门级 PC，保留 Panther Lake 的基础架构，并通过封装、Die 面积、I/O 配置和优化主板设计降低平台成本。    A move by the Department of Justice to block Arizona’s election law HB 2492, seeking to stop non-citizens from voting, has triggered an angry reaction from Mark Brnovich, currently serving as the state’s 26th Attorney General.,"In addition to free rooms and transportation for those illegally entering our country, the DOJ now wants to give them a chance to vote," Brnovich was cited as fuming by Fox News Digita.,As the DOJ announced on Tuesday it had formally filed the lawsuit, calling the bill a "textbook violation of the National Voter Registration Act," Arizona’s AGquipped: "It's another round of Brnovich v. Biden. I will see you in court…again.",It’s another round of Brnovich v. Biden as his DOJ continues its attempts to undermine our election integrity laws. I will see you in court. Again.— Mark Brnovich (@GeneralBrnovich) July 5, 2022,“Arizona has passed a law that turns the clock back on progress by imposing unlawful and unnecessary requirements that would block eligible voters from the registration rolls for certain federal elections," said Kristen Clarke, assistant attorney general for the Justice Department's Civil Rights Division, in a statement.,She added that the DOJ would continue to “use every available tool to protect all Americans' right to vote and to ensure that their voices are heard.",The DOJ’s Civil Rights Division had already written to Brnovich in June to inform him the agency intended to file a lawsuit against the state over its recently enacted voting law.,The Justice Department argued this new legislation, signed in March by Arizona Republican Gov. Doug Ducey, violated the National Voter Registration Act, as it requires ‘documented proof’ of citizenship, such as a government-issued identification, like a driver's license, tribal ID or passport, to vote in federal elections.,The DOJ has pointed to the 1993 National Voter Registration Act to argue its case.,The Act “requires Arizona to ‘accept and use’ a completed and valid Federal Form to register qualified applicants to vote in all elections for federal office," Assistant Attorney General Kristen Clarke stated in the letter.,"Such applicants need not provide additional documentation to prove their citizenship to be registered to vote in federal elections," she added.,‘Election Safeguards’,Mark Brnovich, however, on July 1 vowed to "defend this law to the US Supreme Court if necessary and defeat the federal government’s efforts to interfere with our state’s election safeguards, as I did last year in Brnovich v DNC," according to Fox News Digital.,GREAT win for the rule of law today. Title 42 is upheld by a federal judge.Our office will continue to do everything in our power to push back against the lawlessness of the Biden Administration. pic.twitter.com/WKQBXp6fXB— Mark Brnovich (@GeneralBrnovich) May 20, 2022,Brnovich, who is also running for the US Senate, added that it was "curious" that the DOJ "would use its resources to challenge a common sense law in Arizona designed to guard against non-citizen voting, while the Biden administration is simultaneously opening our borders to encourage a flood of illegal immigration.",He concluded by questioning whether the federal government was seeking to “undermine” the state’s sovereignty and “destabilize” the election infrastructure.,“I hope this is not your intention," Brnovich was cited as saying.,GOP Cites 'Skewed' Voting as Arizona Woman Pleads Guilty to Illegal Early Ballot Collection Scheme5 June, 13:20 GMT,The legislation recently enacted by Arizona comes as part of a push to stop non-citizens from voting.,Back in 2013, the Supreme Court rejected a bid by Arizona to require its voters to provide proof of citizenship in order to participate in federal elections. The ruling did allow the requirement for state elections.,Arizona is one of a swathe of key battleground states where Republican state lawmakers have been arguing the need for changes to voting procedures. The drive came in the wake of the November 2020 elections, which ex-president Donald Trump has repeatedly slammed as marred by voting “irregularities” that were wielded to “rig” the vote in favour of his rival – Democrat Joe Biden. He blamed manipulations involving electronic Dominion voting machines, as well as mail-in ballots in key swing states. However, state courts threw out Trump’ss complaints, citing lack of evidence.,As Gov. Doug Ducey signed the bill into law on March 30, he stated:,"Election integrity means counting every lawful vote and prohibiting any attempt to illegally cast a vote. H.B. 2492 is a balanced approach that honors Arizona's history of making voting accessible without sacrificing security in our elections."。性能方面，Wildcat Lake 最高提供 40 TOPS 的平台 AI 算力，最高可达到 Raptor Lake U Refresh（酷睿 100 系列）的 2.7 倍；创作与生产力性能最高提升 2.1 倍，处理器功耗降低 64%。封装方案上，英特尔为降低封装成本和良率损失，Wildcat Lake 没有沿用 Panther Lake（酷睿 Ultra Series 3）的 Foveros 方案，改为使用有机多芯片封装（Multi-Chip Package，MCP）和 UCIe（Universal Chiplet Interconnect Express）方案。其中有机多芯片封装是一种将多个功能不同的裸芯片（Die）垂直堆叠或水平排列，共同封装在同一个有机基质载板（Organic Substrate）上的先进封装技术。

B | 而 UCIe 是半导体行业内的一个开源、标准化的芯粒（Chiplet）互连规范，定义了同一个封装内部（On-Package）不同芯片之间的通信标准，旨在打破过去的壁垒，让来自不同厂商、采用不同晶圆工艺节点的芯片能够像拼乐高积木一样，无缝地组装和协同工作。英特尔 Wildcat Lake 的计算 Die 采用 18A 工艺，I/O Die 采用台积电 N6 工艺。

C | 18A 支持双裸片方案的 UCIe 连接。这一变化也带来代价。UCIe 的凸点间距为 110 微米，Foveros 为 36 微米。更大的间距要求更高的 GT/s 速率，并扩大 I/O 与控制器区域，让 Wildcat Lake 的 UCIe Die 间接口面积比 Foveros 方案大 70%。与 Panther Lake 相比，Wildcat Lake 的计算 Die 面积缩小 38%。具体变化包括：Xe 图形核心最多 2 个，Panther Lake 为 4 个；保留用于 AI 的 XMX，取消光线追踪功能。NPU 减至最多 1 个，NPU 算力为 17 TOPS，平台总算力为 40 TOPS；Panther Lake 平台为 53 TOPS，NPU 为 3 个。P-Core 减至最多 2 个，Panther Lake 为 4 个；保留相同单线程性能，末级缓存从 12MB 减至 6MB。取消 IPU（图像处理单元）和用于摄像头的 USB 2 ISP。取消专业媒体功能。LP5 内存位宽从 128 位降至 64 位，系统缓存从 4MB 减至 2MB。显示管线最多 3 条，Panther Lake 为 4 条；保留 4K 60Hz 和 UHBR20 支持。附上相关图片如下：。
