HOUSTON, Nov. 29 (Xinhua) -- World number one Fan Zhendong of China defeated Swede Truls Moregard 4-0 to take the men's singles title while Wang Manyu was crowned as the women's singles world champion at the World Table Tennis Championships here on Monday.

Fan lived up to his billing as the world's best player as he ended the dream run of Moregard with a straight-game 4-0 victory (11-6, 11-9, 11-7, 11-8).

"I'm really happy. I was really feeling nervous before the match because I wanted to win the honor for my team and country. With this latest win, I'll be looking ahead with more confidence as I continue to develop my career," said Fan.

Fan, 24, is famed for his excellent technique and explosiveness. He achieved the top spot in the world rankings after holding position No. 2 for 29 consecutive months, starting from November 2015.

"It's disappointing to lose, but I'm happy to have reached the final. Fan is the world's number one for a reason and it's a tough match. I'm just looking forward to going home and celebrating my silver medal with my friends and family," said Moregard.

The 19-year-old Swede has underlined his growing credentials with sterling performances all week, stunning his more illustrious opponents, including Timo Boll, Ahmed Saleh, Chuang Chih-Yuan, Patrick Franziska, Lim Jonghoon and Quadri Aruna.

On the women's part, world No. 4 Wang Manyu beat compatriot and world No. 2 Sun Yingsha 4-2 (11-13, 11-7, 6-11, 11-6, 11-8, 17-15) in a nail-biting match.

Sun seized the early initiative by winning the first game 13-11, taking control of the opening contest with her compact strokes, speed and aggression. Wang has however leveled the score 1-1 after winning the second game 11-7.

The advantage swung back to Sun who takes a 2-1 lead after winning the third game 11-6. Then, the match was evenly poised at 2-2 with Wang dominating and winning the fourth game 11-6.

Wang led 3-2 after winning the fifth game 11-8. After saving six game points in the sixth game, Wang finally took down Sun 17-15 in the compelling spectacle.

"I'm really excited right now. I don't think there are any losers tonight. Yingsha and I are very good friends, and we inspire each other to give our best. I would like to thank Yingsha for putting up a good fight and also all the fans who have been supporting us," said Wang.

"Despite this defeat, I'm pleased I'm able to reach the final. Congratulations to Wang who deserves this victory. We are very familiar with each other, but I made several mistakes during this match and she played better than me today. I'm grateful for all the support I've received and will continue to work hard," said Sun.

Earlier in the day, Wang and Sun combined to retain the women's doubles title with a straight-game victory over Japanese combination Mima Ito/Hina Hayata 3-0 (11-9, 11-7, 11-8).

Hayata and Ito called an important timeout in the third game, overturning a 4-1 deficit to take a 5-4 lead. But it's not enough as Wang and Sun closed out the match in style.

"We are very excited to win this title. Mima and Hina have very quick, smooth connections and they are strong opponents. But, we have developed a lot ourselves and I think the key to winning this match was because of our bond and understanding of each other," said Sun.

"We prepared for every difficulty that we could have met in this match. We tried to just play our way in the match. Thank you to all the fans who supported us," said Wang.

In the men's doubles, Mattias Falck and Kristian Karlsson become the first pair from Sweden to land the title since 1991. South Korean opponents Jang Woojin and Lim Jonghoon fought bravely until the end and produced a solid effort to claim game three.

However, the main applause was reserved for Falck/Karlsson who bounced back strongly, saving two game points in the fourth to secure a magnificent 3-1 victory.

The Swedish combination defeated top seeds Lin Gaoyuan/Liang Jingkun of China in Sunday's semifinal, after overcoming Fan Zhendong/Wang Chuqin in Saturday's quarterfinal clash.

On Sunday, Chinese duo Wang Chuqin and Sun Yingsha outplayed their Japanese opponents Hina Hayata and Tomokazu Harimoto 3-0 to take the mixed doubles crown. Enditem

  (注:本文的续航测试是在风扇模式——标准模式下进行的。其余所有性能测试,均是在风扇模式——高效模式下进行的,以便展现这款轻薄本的最优性能。)

  通过CPU-Z、Geekbench 5这两款软件测试可知,锐龙7 5800H的单核性能以及多核性能均非常强,在生产力和游戏方面均大有可为。

  内存延迟为75.1ns,表现也不错。

  这款512GB M.2固态硬盘的运行模式为PCIe 3.0 x4。

  通过CrystalDiskMark这款测试软件的成绩来看,这块SSD非常的不错,顺序读取速度超过了3500MB/s,顺序写入速度超过了2900MB/s。

  接下来再来重点瞧瞧显卡。RTX3050笔记本电脑GPU基于GA107显示核心打造,拥有2048组CUDA核心、32组光栅单元以及64组纹理单元,搭配有128bit位宽、4GB容量的GDDR6显存。

  华硕无畏Pro15锐龙版这款RTX3050笔记本电脑GPU的默认的GPU频率为712MHz、Boost频率为1057MHz,显存频率为1375MHz(等效11000MHz)。

  根据NVIDIA官方的阐述,NVIDIA Ampere架构拥有第2代RT Core(光线追踪核心)、第3代Tensor Core(张量核心)和全新SM多单元流处理器)。运行速度更快,效能更高,SM中FP32的吞吐量翻倍。第二代RT Cores,光线与三角形求交计算的吞吐量翻倍,动态模糊性能大幅提升。第三代Tensor Cores,优化稀疏网络性能,大幅提升AI计算效能,可以说此代架构进步非常明显。

  值得一提的是,于今夏登场的RTX3050同样支持光线追踪技术,将入门级独显的游戏体验带入了一个新高度。NVIDIA独有的DLSS 2.0与Reflex低延迟技术,更是能够提高游戏流畅度,并且生成精美、清晰的动态画面。

  这款显卡的性能到底如何呢?笔者会从生产力和游戏两方面进行测试。

  首先便是创意设计领域的测试,笔者选用的工具为Adobe Premiere Pro,它可是享誉全球的视频创作工具。

  导出一段480p画质、15帧/秒帧速率、长度11分15秒的视频。在开启显卡硬件加速之后,导出时间仅用了3分06秒,这速度比单用处理器导出要快上好多,足以见得先进的RTX显卡在视频领域的重要性。

  接下来再来瞧瞧这款轻薄本的游戏性能。

  游戏性能基准测试——3DMark

  游戏实测——《赛博朋克2077》

  游戏实测——《古墓丽影:暗影》

  《赛博朋克2077》和《古墓丽影:暗影》都是当今很热门的光追游戏大作,极具代表性。实测可知,不开光追特效,华硕无畏Pro15锐龙版在1080p分辨率下基本上是可以玩的。如果想开启光追特效,建议大家降低分辨率或者画质,以提升游戏帧率。

  可以说,应对轻游戏、轻娱乐的需要,这款轻薄本已能够比较好地胜任。

  从PCMARK 10的测试结果来看,这款轻薄本在常用基本功能和生产力的成绩很好,数位内容创作和游戏的成绩较好。

  续航测试

  利用PCMARK 10,笔者继续对这款轻薄本进行了续航能力实测。

  【续航测试时的机器状态】

  一,拔掉鼠标、耳机、U盘等一切外接设备。

  二,显示屏亮度调至50%。

  三,关闭Wi-Fi连接。

  最终,这款轻薄本在PCMARK 10现代办公续航项目测试中,实现了11个小时33分钟的成绩,表现很好,能够满足一整天强度较高的移动办公需求。

  散热性能测试

  笔者利用AIDA64自带的压力测试,将对这款轻薄笔记本进行CPU+GPU的双烤机测试。

(注:笔者所处的室温维持在26摄氏度左右)

  开启双烤机10分钟之后,这款轻薄本的CPU温度稳定在了约87℃左右,频率稳定在了约2.7GHz,此时功耗约为35W。GPU温度温度稳定在了约71℃左右,此时功耗约为50W。

  开启双烤机10分钟之后,笔者还对这款轻薄笔记本的键盘面进行了红外线热成像测试。此时,键盘表面局部区域的温度已达50℃左右。考虑到它轻薄的身材以及不俗的配置,这样的温度表现其实还是可以的。

  显示屏测试

  利用红蜘蛛校色仪,笔者最后再来好好测一测这款轻薄本的OLED屏幕。

  注,此次测试是在这款轻薄本默认的显示模式下进行的。

  第一项:色域测试

  (测试项目介绍)色域,指某种设备所能表达的颜色数量所构成的范围区域,即各种屏幕显示设备、打印机或印刷设备所能表现的颜色范围。色域值越大,设备所能够显示的颜色就越多。

  这款轻薄本的屏幕具备了96.9%的DCI-P3色域覆盖率,126.9%的DCI-P3色域容积率。对于笔记本屏幕来说,这样的色域表现属于相当棒的。

  第二项:色彩精准度测试

  (测试项目介绍)屏幕上显示的颜色,往往会跟现实生活当中人眼看到的颜色有偏差。颜色差异越小,显示器当然就越好了。

  测试标准:

  当△E≤1时,人眼几乎不能辨别两种颜色的差异;

  当1<△E<3时,人眼需要比对后方能辨别细微的颜色差异;

  当△E≥3时,人眼可以辨别出颜色差异,并认为是两种相近的颜色。

  当△E≥5时,大多数人眼可以看出颜色差异,并认为是完全不同的颜色。

  平均△E为0.74,△E≥2的颜色完全没有,最大△E仅为1.8,这样的色准精准度也堪称是相当的棒,着实能够媲美很多专业级的摄影修图显示器了。确实很棒!

  产品总结

  华硕无畏Pro15锐龙版具备出色的OLED屏幕,一流的A、N硬核组合,给力的固态硬盘,较为丰富的I/O接口,足够长的续航能力,还有MyASUS主控中心提供的丰富功能设置,这6点均给笔者留下了相当好的印象。总的来说在6299元这个价位上,华硕这次可谓诚意满满,给足了性价比!

  实实在在的好机器,这就是笔者对这款轻薄本最终的点评,广大用户们放心买就是了。目前在华硕京东自营官方旗舰店,这款新机已经上架了,喜欢的朋友们可以前往购买。
