A | MIAMI -- Tropical Storm Tammy formed Wednesday afternoon in the Atlantic Ocean, putting a group of islands on alert for its expected approach.The Miami-based National Hurricane Center said Tammy was centered at 5 p.m. EDT about 625 miles (1,005 kilometers) east of the Windward Islands. It was moving briskly to the west at 23 mph (37 kph) and expected to gradually strengthen in coming days.Tropical storm watches have been issued for Barbados, Dominica, and Martinique and Guadeloupe. Forecasters said tropical storm conditions were possible in the region starting within 48 hours and that further watches and warnings will likely be required Wednesday night or Thursday. Tammy is initially expected to spread heavy rains over the northern Windward and Leeward Islands through Friday and then across the U.S. and British Virgin Islands and Puerto Rico over the weekend, according to the hurricane center.The center's opening advisory on Tammy said total rainfall could measure between 3 and 6 inches (7-14 centimeters) with maximum amounts of 10 inches (25 centimeters) in some spots in the northern Windward Islands and Leeward Islands. Lesser rainfall amounts are expected in the British and U.S. Virgin Islands into eastern Puerto Rico, the hurricane center added.The prospect of heavy rains as Tammy nears those islands raises a threat of scattered flash flooding, urban flooding and isolated mudslides in higher terrain, according to meteorologists.。

B | 令人遗憾的是，AMD没有在CES上宣布期待已久的7nm Zen2处理器。AMD首席执行官苏子峰（su zifeng）表示，第三代Ryzen处理器将于今年中发布，并将是第一个支持PCIe4.0的处理器。AMD显示了一个名为“Matisse”的7-NM CPU代码，封装了两个芯片：一个由TSMC制造的8核7-NM芯片和一个由Grofford提供的带有双内存控制器和PCI通道的14纳米输入/输出芯片。AMD表示，这将是全球首款7纳米游戏CPU，也是首款支持PCIe4.0x16的主流CPU。目前，AMD还没有指出8核处理器是该系列的最高规格。根据AMD的说法，当前的频率不是最终的频率，因为它离发布日期还很远，但它肯定支持当前的AM4主板。AMD使用8核处理器和Intel的i9-9900K在Cinebench R15上运行，AMD的7NM CPU得分2057，i9-9900K得分2042，相比之下，Ryzen的前一代得分为72700x，约为1754。AMD表示，这两个系统使用相同的主板、内存、固态硬盘，唯一的区别是CPU，英特尔的总功耗为180W，AMD的总功耗为133W。
