Police seek motive in deadly Sweden school attack******

AFP

Bouquets of flowers lie on stairs as people hug outside the Malmo Latin School on March 22, 2022 in Malmo, Sweden, a day after two women were killed.

Police in Sweden were Tuesday attempting to determine why an 18-year-old student allegedly killed two teachers at a high school a day earlier in an attack that has shaken the country.

The two victims, both women in their 50s, were teachers at Malmo Latin, a large high school in Sweden's third-biggest city, police said at a press conference on Tuesday.

Media reports said the suspect, whose name has not been disclosed, was armed with a knife and an axe, though police have not confirmed that information.

Police chief Petra Stenkula said police had seized "several weapons that are not firearms" at the scene.

Investigators were now trying to determine whether the suspect specifically targeted his victims or chose them at random, and whether he had planned to attack more people.

"We don't know yet if he had any connection to these employees", Stenkula told reporters.

The student "has no criminal record", she said, adding that police were looking into his background and movements prior to the attack.

Investigators were on Tuesday searching the suspect's home in the nearby town of Trelleborg, she added.

Police were alerted to the attack at 5:12 pm (1612 GMT) and a first patrol was able to enter the school minutes later.

About 50 students and teachers were inside at the time, and news footage showed heavily equipped and armed police inspecting the interior of the building.

- Recent attacks -

The suspect was arrested on the third floor just 10 minutes after the first alert, putting up no resistance, Stenkula said.

His two victims were lying on the floor nearby, she added.

The teachers were rushed to hospital for treatment but their deaths were announced later in the evening.

According to daily Aftonbladet, the alleged attacker called emergency services to say where he was and that he had laid down his weapons, and confessed to the killings.

Swedish Prime Minister Magdalena Andersson on Tuesday expressed her "sadness" and "consternation" over the attack.

At the high school, which was closed on Tuesday, a support group has been set up for teachers and students, local authorities said.

"Everyone is deeply shocked. Devastated," a teacher at the school who didn't want to be identified told AFP on Tuesday.

"It's an awful crime, it's impossible to take it all in", she said, standing outside the school where a group of about 20 students stood hugging and crying, some with flowers to lay down on the ground.

School attacks are relatively rare in Sweden, which has in recent years grown more accustomed to shootings and bombings in underworld settlings of scores that kill dozens of people each year.

But several serious incidents have taken place at schools in southern Sweden in recent months.

In January, a 16-year-old was arrested after wounding another student and a teacher with a knife at a school in the small town of Kristianstad.

That incident was linked to a similar knife attack in August 2021 in the town of Eslov, about 50 kilometres (30 miles) away, when a student attacked a 45-year-old school employee.

No link has been established between those two events and the Malmo attack.

英特尔Evo实力见证!i7******

  在刚刚结束的英特尔Evo超能轻薄体验日上,英特尔一口气推出了40款Evo认证笔记本,再次掀起了一波英特尔Evo品牌的热潮。

  在笔者看来,当看到贴有“英特尔Evo品牌”贴纸的移动PC的时候,人们放心购买就好了。它代表了卓越,代表了这款移动PC具备当今一流的移动办公体验,是英特尔为消费者精挑细选的精品电脑。

  面对英特尔在轻薄移动PC平台上的成就,或许有些A饭们会拿英特尔处理器的核心数量以及线程数量说事,认为英特尔处理器的核心数量没有AMD的多,性能未必有AMD的轻薄笔记本强!那么,事实真的如此吗?

  这个问题好办,咱比一比就知道了!目前从产品定位来看,英特尔面向轻薄笔记本平台推出的最强处理器是酷睿i7-1195G7,4核心8线程设计。AMD面向轻薄笔记本平台推出的最强处理器是锐龙7 5800U,8核心16线程设计。

  从核心数量以及线程数量来看,AMD确实要比英特尔给的更多。而实际的性能表现呢,笔者得测了之后才能知道。

  此次生产力性能对比测试,英特尔这边选用的机型为微星尊爵Prestige 14 Evo,它通过了英特尔Evo品牌认证。AMD那边选用的机型为联想YOGA 14c 2021款 锐龙版。

  内存方面,这两款轻薄本均搭配的是2×8GB LPDDR4x-4266内存。LPDDR4x-4266是目前轻薄笔记本平台所能都搭载的速度最快的内存。这样也保障了处理器对比的公平性。

  项目一(基准测试):CPU-Z

  CPU-Z作为一款享誉全球的专业CPU检测工具,不仅简单易用而且完全免费,使用该软件可以迅速检测出CPU的所有详细信息,以及缓存、主板、内存、SPD、显卡等所有硬件信息都可以使用它准确检测出来。并且,该软件还加入了测试功能,可对CPU的性能进行简单快捷的测试。

  测试小结:从CPU-Z的性能测试来看,酷睿i7-1195G7单核性能占优,锐龙7 5800U多核性能占优。

  项目二(综合测试):CrossMark

  CrossMark是一款专门测试电脑生产力性能的软件,目前在业界逐渐流行起来。需要使用的用户们可以到Windows 10应用商店里面进行下载。注意,我们中国用户需要将Windows 10系统的语言切换成英文,才能正常运行这款软件。

  测试小结:在此项测试中,酷睿i7-1195G7全面胜出。

  项目三(综合测试):PCMark 10

  PCMark 10是PCMark行业标准化PC基准测试系列工具的最新版本。PCMark 10针对Windows 10新增了已改善的工作负载,变得更快速、更易于使用。PCMark 10含有一整套全面的测试项,涵盖现代办公场所中的各种任务。通过一系列性能测试,自定义运行选项和新的电池寿命数据图表,PCMark 10是现代办公的完整PC基准测试。

  测试小结:在此项测试中,锐龙7 5800U全面胜出。

  项目四(核显性能测试):SiSoftware Sandra

  SiSoftware Sandra 2021是一款强大的电脑性能测试软件,相比众多的跑分软件,SiSoftware Sandra 2021能够更好地体现出PC的生产力性能。

  核芯显卡的性能对于当今轻薄笔记本来说也是相当重要的。它能够辅助CPU进行运算,帮助提升工作效率。基于此,笔者有必要对核芯显卡的性能进行一下测试。

  酷睿i7-1195G7内建有英特尔新一代Xe架构核芯显卡。锐龙7 5800U则内建有AMD Radeon Graphics显卡。

  测试小结:此项测试,酷睿i7-1195G7在2项测试中占优,锐龙7 5800U在一项测试中占优。

  项目五(视频编辑性能测试):格式工厂

  格式工厂是国产优秀的视频格式转换工具,发展至今已经成为国内领先的视频图片等格式转换客户端。格式工厂致力于帮用户更好的解决文件使用问题,现拥有在音乐、视频、图片等领域庞大的忠实用户,在该软件行业内位于领先地位,并保持高速发展趋势。

  测试小结:此项测试,仅凭CPU运算的话,锐龙7 5800U的表现是要更好的。但是当开启GPU加速之后,酷睿i7-1195G7核芯显卡的加速效率就展现出来了,最终表现反超锐龙7 5800U。

  在格式工厂这款软件当中,锐龙7 5800U在开启GPU加速之后,反而出现了严重的负优化现象。有待改善!

  附加项目一(固态硬盘测试):CrystalDiskMark

  CrystalDiskMark是一个测试电脑硬盘检测工具,简单易于操作的界面随时可以测试存储设备,测试存储设备大小和测试数字都可以选择,还可测试可读和可写的速度。

  估计会有读者质疑,此次不是测试处理器吗,怎么测试上固态硬盘了?这是因为固态硬盘性能的上线跟处理器也是息息相关的。

  酷睿i7-1195G7处理器支持PCIe4.0,因此与之搭配的固态硬盘性能的上限就高。反观锐龙7 5800U,这款处理器仅支持PCIe3.0,因此与之搭配的固态硬盘的性能上限就较低。

(左为微星轻薄本的成绩,右为联想轻薄本的成绩)

  测试小结:此项测试,英特尔平台明显速度更快。这主要得归功于酷睿i7-1195G7是支持PCIe4.0的。

  附加项目二(外接设备的扩展性):英特尔拥有自研的Thunderbolt 4接口

  对比外接设备的扩展性,搭配有Thunderbolt 4接口的英特尔轻薄本肯定是要普遍优于AMD轻薄本的。

  Thunderbolt 4,它是英特尔现在乃至未来主导的通用线缆连接解决方案,仅需一个接口即可囊括多种接口功能,进而让PC,特别是轻薄笔记本的接口化繁为简,在保持强大的扩展功能基础上实现更轻薄的机身设计。

  Thunderbolt 4接口具备40Gbps的速率上限,而现阶段AMD轻薄本所能够支持的Type-C接口,最高仅支持USB3.2 Type-C,具备20Gbps的速率上限。

  测试小结:外接设备的扩展性方面,英特尔平台的优势是很大的。

  全文总结

  单从人们常用的跑分软件来看,酷睿i7-1195G7与锐龙7 5800U互有各自的优势项目,真不太好说谁比谁更优。因此,A饭们不要以为锐龙7 5800U核心数量、线程数量比酷睿i7-1195G7多了一倍,就觉得锐龙7 5800U如何如之何了!这种主观意识是不够准确的。

  如果真要分出个上下、论出个高低的话,笔者个人认为酷睿i7-1195G7这边毕竟拥有PCIe4.0以及Thunderbolt 4的加持,整体上看英特尔的轻薄本在生产力方面是要优于AMD的。

  大家可不要小小瞧了固态硬盘对于整个移动PC的重要性。速度就是生产力!例如对于视频创作工作者们来说,使用更快的PCIe4.0固态硬盘传输视频素材,加快工作效率,进而能够早点下班,早点回家陪伴家人,美好的生活不就是如此吗!

  还有就是Thunderbolt 4,目前在英特尔轻薄本上面普及的也越来越多了。大家可以想象下,轻薄笔记本白天可以带着外出办公,晚上回家之后更可以将轻薄笔记本接上强大的Thunderbolt 4外接显卡扩展坞,实现强大的专业图像性能,满足视频剪辑、创作设计等专业需要,强到可以媲美性能一流的台式机!如此美妙的体验,AMD轻薄笔记本目前是无法给予消费者的。

  好了,以上就是笔者自己的一些观点,希望对大家在选购轻薄笔记本时有所帮助。目前通过有英特尔Evo品牌认证的机型已越来越多了,大家可以随心选择,让英特尔的卓越性能助生活和工作更精彩!
