华硕当然没有在 2023 年的电竞笔电机海中缺席，新推出的 18 寸 ROG Strix Scar 18（2023），使用当前最顶级规格的 Intel Core i9-13980HX 处理器与 NVIDIA GeForce RTX 4090 笔电 GPU，搭配 16 ：10 的 18 英寸 240 Hz 的 QHD Nebula 显示器，更同时整合了 MUX 独显直连开关和 NVIDIA Advanced Optimus 自动切换技术，就是要给玩家最狂热的性能体验。

设计与规格

ROG Strix Scar 18 （2023） 外观主打鲜明、显眼的视觉设计，包括上盖 Logo、机身尾部以及键盘下边缘都配置了可寻址的 RGB 灯效，而且亮度颇高。

机身上盖采用喷砂工艺的金属材质外壳，经过黑色阳极氧化处理过后，表层再覆上防指纹涂层。 斜向的切割线则运用高功率激光抛光，让整列的 ROG 败家之眼 Logo 在低调与显眼之间取得完美平衡。

Intel Core i9-13950HX 处理器是第 13 代 Intel Core HX 系列最高阶的产品，采用独立 SBGA 封装设计，内含 8 颗 P-core 和 16 颗 E-core，P-core 最高频率可达 5.5 GHz，基础功耗 55W，最大 Turbo 功耗 157W。

为了发挥最大性能，ROG Strix Scar 18 同时配备了 MUX 独显直连开关和 Dynamic Display Switch 芯片。 近年高阶电竞笔电几乎都可看到 MUX 独显直连开关的身影，能够强制系统的线程直通独立 GPU，不必再绕过核显。

Dynamic Display Switch 则是英伟达 Advanced Optimus 技术的重要组件，能够在不需要重开机的情况下，依照需求动态切换出 GPU 直连的最大性能模式，或是只用核显的省电模式，比一般只采用 MUX Switch 芯片的机种拥有更大的便利性。

为了压制如此强大的顶级处理器与 GPU 热量，ROG Strix Scar 18 动用了高达 7 根热导管的强大散热器，完整覆盖 CPU、GPU、VRAM、VRM 供电模组等区域，加上液态金属强化热传导，并且把铜质散热鳍片移至更靠近排气口的位置，搭配 3 颗风扇做为动力，让热量能更快速抽离机身。

这块 18 寸 16 ：10 的 QHD+（2560 x 1600）240 Hz 的屏幕，虽然没有用上 mini-LED 背光，但其峰值亮度依旧可达 500 nits，不只显色能力覆盖 100% DCI-P3 色域、通过 Pantone 色彩认证，更支持「Dolby Vision 杜比视界」这个当前效果最好的 HDR 效果。

键盘面板外壳使用半透明的塑料外壳，维持机身结构坚固之余，还能营造科技透视感。 机身尾部边缘的 ROG 装甲铭牌是通过磁吸式固定的，用户也能运用 3D 打印打造出风格独特的铭牌。 机底外观也不马虎，透过两种不同方向的斜纹钻切，组合出 ROG 字样的进气口。

音效方面总计塞入了 4 个喇叭单体，分别是正面靠近转轴处的 2 个高音单体，以及机底下缘左右两侧的低音单体，并整合 Dolby Atmos 杜比全景声环绕音效技术，打造出 5.1.2 声道虚拟环绕音效。

性能实测

我们准备了配置 Core i9-12900HX CPU + NVIDIA GeForce RTX 3080 Ti Laptop GPU 的前代旗舰笔电当作对照组，看看 ROG Strix Scar 18（2023）性能领先了多少。

CPU 渲染能力对比

从 Cinebench R20 / R23 测试中可以看到 Core i9-13980HX 的单核和多核成绩已超越前代桌面级旗舰 Core i9-12900K，连同 Blender 3.4.0 和 V-Ray 5 的 CPU 多核渲染成绩大致介于 Core i9-13900K 和 Core i9-12900K 之间，但稍微靠近 Core i9-12900K 一些。

CPU 综合性能对比

Geekbench 6 的表现不俗，多核成绩仅落后 Core i9-13900K 约 17%。

GPGPU 通用运算能力对比

GeForce RTX 4090 Laptop 的 FP32 单精度浮点运算性能大约是 PC 端的 GeForce RTX 4080 的 85%，但已几乎是 GeForce RTX 3080 Ti Laptop 的 2 倍。

GPU 渲染

GeForce RTX 4090 Laptop 凭借着 Ada Lovelace 架构第 3 代 RT Core 更强劲的光线追踪性能，Blender 3.4.0 和 V-Ray 5 最高分别领先 GeForce RTX 3080 Ti Laptop 的 2.4 倍 / 1.9 倍成绩。

3DMark

CPU Porfile 类似先前提到的多核心渲染，最大线程测试中，Core i9-13980HX 成绩介于 Core i9-12900K 和 Core i9-13900K 之间，其余较小线程数量的成绩比较贴近 Core i9-12900K，互有胜负。

GPU 性能方面，GeForce RTX 4090 Laptop 在模拟 DirectX 12 游戏的 Time Spy / Time Spy Extreme 取得的 GPU 分数较 GeForce RTX 3080 Ti Laptop 增长 56% - 58%，模拟 DirectX 12 Ultimate 游戏的 Speed Way 测试则进一步成长到 70%。

游戏表现

我们从 GPU 压力最大的 4K 2160p 分辨率来看，配备 GeForce RTX 4090 Laptop + Core i9-13980HX 的 ROG Strix Scar 18（2023），在非光追游戏的成绩平均是前代旗舰的 1.5 倍以上。

若再启用光线追踪并套用 GeForcr RTX 40 系列 GPU 独有的 DLSS 3 功能，性能平均是前代旗舰的 2.4 倍，最高可达 3.2 倍。

若将我们测试的 17 款（含光追）游戏的 4K 分辨率成绩平均起来将近 90 fps，画面流畅度可算是畅玩等级。 分辨率降至 WQHD 1440p 时，平均 fps 更逼近 150 fps。

总结

从实测可以看到，华硕 ROG Strix Scar 18 （2023） 所配备的 Intel Core i9-13980HX 各项表现都相当优异，能超越前代的桌面级旗舰 CPU，甚至距离当代桌面级旗舰 CPU 并不远，确实相当厉害。

而 NVIDIA GeForce RTX 4090 Laptop GPU 在不套用各种加成的情况下，就可以跑出前代笔电旗舰 GPU 的 1.5 倍以上的性能。 再加上光线追踪与 DLSS 3 等特效的加持，部分游戏甚至有超过 3 倍的画面流畅度。

同时整合 MUX 独显直连开关和 NVIDIA Advanced Optimus 自动切换技术的设计，则让玩家保有性能模式切换的便利性与可控度。

如果你正打算购入当代顶规笔电，240 Hz、QHD+ 分辨率、支持 Dolby Vision 杜比视界的屏幕也能满足你，那么配备 Core i9-13980HX CPU + GeForce RTX 4090 Laptop GPU 的 ROG Strix Scar 18 （2023） 确实是极具性价比的采购选项。

倪迹段2293cpu突然降低电压,CPU突然降频(非高功耗时刻)
王褚要17550863204 ______ 12代采用的大小核心设计,在Windows 11的支持下有合理的调用措施.大核的最高睿频为5.3G,小核的最高睿频为3.9G.如果实在难受建议将小核心全部屏蔽掉.

倪迹段2293i59400f和12400f差多少
王褚要17550863204 ______ 都差不多,后者性能优越一些.因为9400的性能就足够用了,例如绝地求生用7400就可以开全高画质流畅运行,目前市面上没有9400带不动的大型网络和单机游戏.只有部分沙盒游戏带不动,例如我的世界和史诗战争模拟器,这俩游戏用12900k都带不动,因为他俩都能无限叠加数值.

倪迹段2293铭瑄b660m终结者搭配什么cpu
王褚要17550863204 ______ 可以从12490,12400处理器起步,往上都可以.660m主板属于中端,12700kf也可以搭配,但是顶端的12900k就不适合,考虑超频,还是选择z690主板比较好.

倪迹段2293小江叔叔两年前存入一笔钱,年利率是3.75%,到期时共得到本金和利息12900元.两年前,小江叔叔 -
王褚要17550863204 ______ 12900/(1+3.75%*2)=12000元 本金

倪迹段2293i912900hx什么档次
王褚要17550863204 ______ i912900hx属于高端旗舰档次,i9-12900HX是一款基于AlderLake架构的笔记本电脑高端级别移动CPU.它拥有6个性能核心(P核心、GoldenCove架构)和8个高效核心(E核心、Gracemont架构),所有内核最多可使用30MB三级缓存.作为HX版本,处理器提供了超频支持,因此可以对CPU内核进行超频.

倪迹段2293amd5800x用什么显卡(显卡降价后怎么配高性能游戏电脑)
王褚要17550863204 ______ 在DIY市场,近期最激动人心的好消息当然是显卡开始逐步降价,同时新一代处理器... 就是它的三级缓存容量仍然不高,虽然旗舰酷睿i9-12900K的三级缓存容量提升到30...

倪迹段2293比泽尔活塞压缩机压缩比是多少 -
王褚要17550863204 ______ 压缩比指在气缸中,排气绝对压力与进气绝对压力的比值. rp(压缩比)=P2[排气压力)/P1(进气压力). 低温型?你要打?℃,饱和温度对应高、低压力自己算吧. 注意:中间压力为低压级排气,高压级吸气. 如比泽尔半封闭往复式双极...
