Core Ultra 7 165U 性能首次亮相:戴尔Latitude 9450 2 合 1 评测
2024Latitude 9450 2 合 1 直接继承了去年的 Latitude 9440 二合一.新款机型引入了英特尔流星湖-U 处理器选项,以取代旧款的猛禽湖-U 系列。除此之外,这两款Latitude 在外观上完全相同,因为今年该系列没有重大变化。
我们的测试机是最高端的配置,配备酷睿 Ultra 7 165U CPU、32 GB LPDDR5x-7467 内存和 512 GB M.2 2230 固态硬盘,售价约为 3000 美元。较低配置的机型采用 Core Ultra 5 125U,内存和存储空间减半,价格便宜几百美元,但所有选项都固定采用 2560 x 1600 IPS 触摸屏。
Latitude 9450 2 合 1 的替代产品包括其他商务可转换产品,如 华硕专家本 B5 Flip, 联想 ThinkPad X13 Yoga G4或 HP EliteBook x360 830 G10.

案例 - 历时一年的设计仍让人耳目一新
去年的Latitude 9440 2 合 1 是对旧版本 9430 2 合 1 的彻底重新设计。 Latitude 9430 二合一.因此,今年的Latitude 9450 2-in-1 只做了很小的改动也就不足为奇了。我们对Latitude 9440 2 合 1 机箱和物理特性的现有评论仍然适用于Latitude 9450 2-in-1。
区分Latitude 9450 2 合 1 与 9440 2 合 1 的简单方法是查看取代 Ctrl 键的新 Microsoft Co-Pilot 键。联想等其他制造商的笔记本电脑也开始采用 Co-Pilot 键。
交流
Wi-Fi 7 是标准配置,而去年的机型 "仅 "支持 Wi-Fi 6E。不过,绝大多数用户仍无法充分利用 Wi-Fi 7 的优势,因此在撰写本文时,升级几乎没有任何区别。
网络摄像头
网络摄像头的质量仍为 2 MP,而 HP EliteBook 1040 G10 或 联想 ThinkPad X13 Yoga G4等机型则配备了 500 万像素传感器,可获得更清晰的图像。
维护
显示屏 - 仅 IPS
触摸屏没有变化,因此用户仍然可以获得与 2023 型号相同的友达光电 B140QAN IPS 面板。这种面板因其缓慢的黑白和灰白响应时间而臭名昭著,会导致非常明显的重影。不过,对于大多数办公任务来说,重影应该不是大问题。
遗憾的是,目前还没有其他显示屏可供选择,这意味着 OLED 和更高的刷新率是不可能的。

性能 - 流星湖-U 对 流星湖-H
测试条件
在运行以下基准测试之前,我们将戴尔优化大师设置为超性能模式。
处理器
Core Ultra 7 165U 是 Core Ultra 7 155U 的 vPro 版本。两者的高速缓存大小和目标时钟频率基本相同,只是 Core Ultra 7 165U 的目标最高频率高出 100 MHz。但实际上,Core Ultra 7 165H 本身并不比 Core Ultra 7 155U 快。
遗憾的是,戴尔 Core Ultra 165U 的表现有些令人失望,其性能与较早的 Ryzen 7 7730U 不相上下。它仍然比去年Latitude 9440 2 合 1 中的酷睿 i7-1365U 快约 10%至 15%,但总体性能提升相对较小。

压力测试
CPU Turbo Boost 可持续性有限,这与上文提到的 CineBench 不尽如人意的结果不谋而合。例如,在运行 Prime95 时,时钟频率和主板功耗分别高达 3.4 GHz 和 44 W,几分钟后才缓慢但稳定地降至 2.2 GHz 和 21 W,以控制温度。下面的截图显示,当 Turbo Boost 不受限制时,核心温度高达 102 C。

图形处理器性能
Core Ultra 7 165U 配备了集成的 Arc 4 GPU,而 Core Ultra 7 155H 配备了集成的 Arc 8。这一微小的标称差异却带来了显著的性能差异,这并不利于我们的戴尔系统。例如,3DMark 结果显示,我们的 Arc 4 比 Arc 8 慢 30% 到 50%。图形性能仍然快于去年的 Iris Xe 96 EU,但优势较小,仅为 20% 至 25%。除非使用尽可能低的设置,否则要求较高的游戏仍然无法运行。有些游戏,如《小小蒂娜的仙境》,如果设置较高,甚至会崩溃。

耗电量
运行Witcher 3 时的平均功耗仅为 36 瓦,而使用旧版 Iris Xe 96 EUs 显卡的Latitude 9440 2 合 1 机型则为 52 瓦。因此,我们的新型号不仅速度稍快,而且功耗更低,每瓦性能更高。这一关键优势可能是电池续航时间更长的原因,下文将对此进行说明。
Latitude 9450 2 合 1 和Latitude 9440 2 合 1 配备了相同的 65 W USB-C 交流适配器。

结论--只是小更新,一切从实际出发
2024Latitude 9450 2 合 1 与 2023 相比优势不大 Latitude 9440 二合一.最重要的变化是CPU和GPU的速度略有加快,电池续航时间更长,这可能会让某些电力用户或旅行者感到满意。除此之外,没有任何令人兴奋的东西能鼓励用户购买它而不是 2023 版。例如,如果能在升级 CPU 的同时提供新的显示屏选项就更好了。
Latitude 9450 2 合 1 与Latitude 9440 2 合 1 的用户体验基本相同。如果你的日常工作无法从本地 AI 加速中获益,那就省点钱,直接购买Latitude 9440 2 合 1 即可。
当然,如今说到笔记本电脑就不能不提到人工智能。Latitude 9450 2 合 1 确实集成了 NPU,以更好地区别于上一代机型。不过,截至本文撰写之时,绝大多数程序尚未使用 NPU。今天购买Latitude 9450 2-in-1 将意味着对 NPU 及其未来在 Windows 中的应用进行投资。如果本地 AI 加速和 Microsoft Co-Pilot 无法满足您的需求,那么Latitude 9440 2 合 1 基本上可以以更低的价格提供相同的体验。
价格和供应情况
戴尔公司目前正在出货 Latitude 9450 2 合 1,基本配置为 Core Ultra 5 125U 的起价为 2320 美元,配置为 Core Ultra 7 165H 的起价略高于 3000 美元。
