戴尔Precision 17 7770评测–其散热需要改造


设计和结构

由于这是一款17.3英寸的工作站,当我们发现它的尺寸时,并不感到惊讶。它的外形是25.95-26.7毫米厚,而它的重量是3.02公斤。总的来说,不算太差。

然而,我们不能不注意到该设备的笨重性。我们认为,唯一能 “拯救 “这个产品的是它很少会被从办公桌上移开。从好的方面看,盖子和底座都是非常坚硬的。机身外板是由铝制成的,而底座则使用了一种未公开的材料,看起来更柔软、更温暖。这表明不是塑料就是碳纤维。

因此,这里的盖子可以用一只手打开。不仅如此,它还可以一直走到平坦的位置。哑光显示屏周围的边框可能有点厚,但顶部的边框容纳了一系列的传感器,包括一个全高清网络摄像头,一个红外人脸识别扫描仪,一个隐私快门,以及其他的传感器,这让你可以使用唤醒和注销功能。

移到底部,我们发现一个背光键盘,它有一个数字键盘。后者具有全尺寸的按键,这很好。总的来说,由于键程比一般的要长,而且有点击反馈,所以打字的体验是比较好的。

虽然触摸板在图片中看起来非常小,但你不应该被欺骗。这是因为笔记本电脑的表面积很大。事实上,触摸板的尺寸为80×115毫米。它的滑行相对平稳,而跟踪非常准确。

现在,如果我们把笔记本倒过来,我们会发现扬声器的切口,以及通风栅。尊敬的是,排气孔放在设备的背面,它本身也相当大。

接口

在左侧,你有一个电源插头、一个LAN端口、一个HDMI 2.1接口、USB Type-A 3.2(Gen. 1)端口、两个Thunderbolt 4接口和一个智能卡阅读器。而在右边,有一个安全锁插槽,一个USB Type-A 3.2(Gen. 1)端口,一个USB Type-C 3.2(Gen. 2)端口和一个DisplayPort 1.4,一个音频插孔,以及一个SD卡读卡器。

despite the common verdict of the Precision 7770, and I agree their performance and design flaws aren’t worth their workstation price premium., but still I ordered one, and didn’t end up returning it. Why? Because on Dell’s Outlet store got one with i9, 64GB RAM, and 16GB A4500 GPU for a relative steal by combining discount codes totaling -81% off, paying $2,100 when sticker price was $9,865!!!!
It has met the needs of my academic research analyzing and training models on large engineering datasets, can even play Forza Horizon 5 at Ultra setting on 3440×1440 widescreen monitor at 60-75 FPS!

The most marketing oriented waste of ressources and money I have seen in recent years. With only 210Watts of AC power available, the mainboard is physically incapable of using CPU and GPU at the same time. Putting this amount of power into components that are half the price will give similar, if not better results. (better because a 4090GPU has a larger baseline powerdraw, and needs to be extra careful to not accidentally fry itself under that flimsy heatsink). This thing is like an 7.2l V8 with a fuelpump capped to 1 Gallon per hour: Overtaking a Big Truck will… Read more »

Can you just upgrade the power supply / wall adapter to 300W+ to get better performance? Also, I understand recent BIOS updates have fixed, or at least mitigated many (all?) of the thermal / amperage management concerns.
