while
you
are
in
another
device’s
pages
without
navigating
back
and
forth.
It
doesn’t
stop
there!
You
can
also
copy
and
paste

on
your
TV
and
/
or
audio
receiver.
We
recommend
figuring
out
what
you
want
to
do
with
your

1.Choose
“Advanced
Setup”
from
the
Main
Setup
Menu.
2.Choose
“Macros.”
3.Select
“Test/Edit
Existing

锐炬xe显卡和mx450哪个好的详细对比介绍

锐炬xe显卡和mx450哪个好的详细对比介绍

锐炬xe显卡和mx450哪个好的详细对⽐介绍对于mx450和锐炬xe显卡两种显卡来说，哪张性能更好⼀点，其中锐炬是Intel第四代集成显卡的名称，英⽂名为IRIS，Xe指的是⼀种架构，你可以简单地理解为它是更厉害⼀点的锐炬，MX450指的就是NVIDIA GeForce MX450，它是⼀款由专业显卡公司英伟达出品的最新⼀代⼊门级独⽴移动显卡。

下⾯我们⼀起去看看。

mx450和锐炬xe显卡哪个好?mx450和锐炬xe显卡对⽐介绍ris Xe MAX移动版最多96个执⾏单元(768个流处理器)、48个纹理单元、24个ROP光栅单元(还有低配版但未公布)，核⼼频率1.35GHz。

桌⾯版则是固定开满全部96个执⾏单元，核⼼频率提⾼到1.65GHz，同时搭配4GB LPDDR4X独⽴显存，带宽为68GB/s——简单计算可知位宽为128-bit，显存频率4266MHz。

技术特性上，Iris Xe MAX制造⼯艺和Tiger Lake⼀样都是10nm SuperFin，API接⼝⽅⾯⽀持DX12.1、OpenGL 4.6、OpenCL 2.0，图形⽅⾯⽀持PCIe 4.0总线、VRS可变刷新率、适应性同步、同步计算(测试)、DLBoost DP4A AI加速指令、AV1视频编码、12位端到端数据，视频输出⽀持eDP 1.4b、DP 1.4、HDMI 2.0b，最多四屏显⽰。

最特殊的地⽅在于，它可以让应⽤在Xe架构的核芯显卡、独⽴显卡之间横跨共同运作，也就是双GPU并⾏。

还有Additive AI功能，⽀持在两个GPU上同时进⾏推理和渲染，加速内容创作⼯作负载。

官⽅测试显⽰，11代酷睿i7-1165G、Iris Xe MAX的组合，对⽐10代酷睿i7-1065G7、MX350显卡的组合，AI性能提升最多可达7倍。

你要来一杯吗 英伟达GeForce MX450独显

你要来一杯吗 英伟达GeForce MX450独显

你要来一杯吗英伟达GeForce MX450独显作者：来源：《电脑爱好者》2020年第22期在轻薄本领域，英伟达旗下的GeForce MX系列几乎一统独显江湖（图1），也是让轻薄本可以流畅驾驭《英雄联盟》、《守望先锋》级别游戏的基本保障。

然而，随着英特尔为酷睿处理器准备了锐炬核显，AMD推出集成Vega核显的移动锐龙之后，GeForce MX系列独显的市场地位便岌岌可危了。

以我们熟悉的GeForce 940MX（包括MX130，二者互为马甲关系）为例，它门在与第10代酷睿i5-1035G7/i7-1065G7集成的锐炬Plus 64的较量中讨不到半点便宜。

哪怕是GeForce MX150（包括MX250，二者互為马甲关系），也无法和锐龙7 4800U集成的Vega 8核显拉开太大的差距。

英特尔第11代酷睿更厉害，其GPU已经换装Iris Xe Graphics（图2），拥有80组或96组EU单元（下文简称锐炬Xe 80或锐炬Xe 96），理论性能已经超越Vega 8，成为了史上第二强的核显，具备挑战GeForce MX350的实力！随着核显性能的不断增强，作为入门级别的GeForce MX独显自然深感压力。

为了迎接来自更强核显的挑战，英伟达也在不断地调整策略，比如2020年初匆忙上阵的GeForce MX350就是由GTX 1050精简而来（图3），拥有远超上代MX250的性能表现。

但正如上文所述，哪怕是MX350，在第11代酷睿集成的锐炬Xe 96核显面前也没有太多嚣张的本钱，因此就在MX350刚刚服役半年之久，英伟达就迫不及待地推出了它的接班人，也就是本文讨论的主角GeForce MX450。

2018年4月，英特尔携手AMD，发布了隶属于第8代酷睿的Kaby Lake-G平台（TDP为65W和100W），该系列处理器的CPU沿用了第7代酷睿KabyLake核心，但GPU却换成TAMD定制的Radeon RX Vega M GH/GL（图4），3D性能等同于GTX 1050和GTX 1050 Ti，堪称史上最强核显。

第11代酷睿绝配英伟达GeForce MX450独显

第11代酷睿绝配英伟达GeForce MX450独显

第11代酷睿绝配英伟达GeForce MX450独显作者：来源：《电脑爱好者》2020年第19期本期特别话题栏目介绍了英特尔最新的第11代酷睿处理器平台，其集成的锐炬Xe核显性能极其强悍，哪怕是当红的MX350独显都成了“拖油瓶”。

好消息是，英伟达最新发布的GeForce MX450，就是可以让第11代酷睿笔记本强上加强的独显。

MX450之所以备受关注，是因为它采用了与游戏本专用的GeForce GTX1650独显一脉相承的TU117图灵架构核心。

在英伟达官网我们已经可以看到它的基本参数：可选GDDR5和GDDR6显存，支持CUDA、Optimus、GPUBoost、Game Ready、DX12_1、OpenGL4.6、Vukan 1.2、OpenCL 1.2等技术。

可惜，官网并未透露MX450的流处理器数量（应该是89 6个或1024个），但无论如何它都将远超MX350的640个，从而获得性能上的大幅提升。

而最令人吃惊的是，MX450竟然成为了GeForce消费级显卡中首发PCIe 4.0的存在！此前显卡领域支持该技术的暂时只有AMDRX 5000系列和NVIDIA旗下的A100計算卡。

当然，刚刚问世的RTX 30系列显卡也会支持它。

考虑到英特尔第11代酷睿TigerLake就主打PCIe 4.0功能，MX450无疑就是新一代轻薄本的御用独显搭档。

MX450与GTX1650的最大差异，应该就是前者的显存位宽大概率会从128bit降到64bit，TDP也会从50W降到25W左右。

但即便如此，MX450的游戏性能也将无限接近上代GTX1050，足以在1080P+中画质下流畅运行很多3A游戏大作。

如果你想了解第11代酷睿和MX450的真实性能，请关注CFan的后续报道。

联想旗下的拯救者（Legion）应该是国内最著名的游戏本品牌之一，如今该家族即将迎来一款主打轻薄便携的15.6英寸新成员——Legion Slim 7i（国内型号待定），该产品的外观与现有的Y7000/R7000很像，但改用航空级铝合金机身，厚度和重量也被压缩到了17.9mm和1.8kg，质感和便携性大幅提升。

近日，英伟达在其官网上更新发布了MX450笔记本独显的相关信息，其中介绍到英伟达MX450独显可选择GDDR5和GDDR6两种规格的显存，并且支持PCIe 4.0總线，能够为笔记本电脑的工作加速，在照片、视频编辑以及游戏方面有更好的表现。

英伟达方面没有提到MX450独显的具体参数，不过结合前不久外媒曝光的信息，MX450独显采用了和GTX 1650移动显卡相同的TU117核心，但是在带宽和显存容量上砍了一刀，仅有64 bit带宽和2 GB显存。

基于台积电12 nm工艺打造，集成了1 024个着色单元、64个纹理贴图单元和32个ROP。

值得注意的一点是，有国外媒体提到MX450独显拥有高频版和低频版2种规格，高频版的基础频率为1 395 MHz，升压频率为1 575 MHz，性能方面略胜于GTX 1650显卡。

而低频版的MX450独显性能仅为高频版的59 %左右，基础频率720 MHz，升压频率为930 MHz，与75 W功率的GTX 1050显卡性能相当，理论性能上还是相当强悍的。

目前英伟达官方并未有关于MX450显卡的任何性能指标介绍，以上的规格以及性能标准都只是基于媒体爆料，不过可信度应该比较大。

此次MX450独显除了性能有了较大的提升外，最大的变化应该是支持PCIe 4.0，这也是为了配合英特尔Tiger Lake 11代酷睿处理器，想换笔记本的朋友可以等下半年的新机。

MX450性能优势巨大，高功率版已能搞定FHD高画质《守望先锋》

MX450性能优势巨大，高功率版已能搞定FHD高画质《守望先锋》

MX450性能优势巨大，高功率版已能搞定FHD高画质《守望先锋》作者：来源：《电脑报》2020年第46期前段时间我们给大家分享了第11代酷睿Tiger Lake处理器强大的性能，尤其是它的Iris Xe集成显卡，性能提升可谓质变，轻松掀翻了AMD的移动集显，甚至可以叫板满血的MX350。

不过随着联想小新Pro 14 2021款的到来，轻薄本移动显卡新标杆再度易主，得交给高功率释放的英伟达MX450了。

联想小新Pro 14 2021借助着两个大风扇和两根粗大的热管，可在持续双负载时让MX450独显保持23W～33W的输出功率，此时i5 1135G7也能有20W的功率，电表功率可达85W——而在如此强大的功率释放下，MX450表现出了强大3D性能，3DMark Time Spy在FHD分辨率下得分高达3661分，领先Iris Xe 80EU满血版的2112分超50%，而作为对比，AMD的R7 4800U的Radeon Graphics得分仅为1100分。

而在全民游戏《英雄联盟》中，标准2240×1400分辨率+最高画质，大乱斗模式，上来就团战，平均可达稳定的135fps～150fps！还有很多读者关心这款笔记本是否能玩《守望先锋》，作为画面漂亮且对抗性激烈的FPS 对战游戏，《守望先锋》要稳定在80fps及以上帧速才能实现基本流畅，稳定110fps以上才是理想情况。

而我们的实测答案是：2240×1400分辨率，预设高画质+75%渲染，开局100fps+，不算太激烈的对抗画面可以维持在95fps左右，流畅达成！如果觉得14英寸屏2240×1400分辨率下人物太小，远距离长枪对射难瞄准，还可以降低分辨率到1920×1200，依然有出色的游戏画面表现，游戏人物也似乎大一些，而帧速更是飙升到122fps左右，相当流畅了！进而，我们也对Iris Xe进行了《守望先锋》测试，结论是：1680×1050分辨率，中画质+系统默认86%渲染，实际对战时最低帧速有75fps左右，最高可达120fps以上，也比较流畅！画面质量虽然有降低也依然可接受。

These resistors are intended for the design of high voltage systems where the system is not exposed to full military or space grade operating conditions. For full military or space grade operating conditions, we recommend Caddock's Type TG Low TC Precision High Voltage Resistors or Type MG Precision High Voltage Resistors.
Cost Effective High Voltage Resistors for Industrial and General Purpose Applications
Type MX Resistors Utilize Caddock's Patented Coating Design
Type MX Precision High Voltage Resistors combine Caddock's Non-Inductive serpentine pattern with a patented, high thru-put screen printed silicone coating. The alignment of the gap in the coating pattern with the gap in the serpentine resistor pattern provides a complete encapsulation of the resistor element. The cap and lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
