日本戴尔Precision 17 7770评测–其散热需要改造
| 3
温度和舒适度，电池寿命
CPU最大负荷
在这个测试中，我们在CPU核心上使用100%，监测其频率和芯片温度。第一栏显示计算机对短时负载（2-10秒）的反应，第二栏模拟严肃的任务（15-30秒之间），第三栏是一个很好的指标，表明笔记本电脑对长时负载的能力，如视频渲染。
平均P核频率；平均E核频率；CPU温度；封装功率
| 英特尔酷睿i7-12850HX (55W TDP) | 0:02 – 0:10 秒 | 0:15 – 0:30秒 | 10:00 – 15:00 分钟 |
|---|---|---|---|
| Dell Precision 17 7770 | 3.18 GHz @ 2.29 GHz @ 89°C @ 101W | 2.82 GHz @ 2.06 GHz @ 90°C @ 90W | 2.77 GHz @ 1.91 GHz @ 82°C @ 85W |
| Dell Precision 16 7670 | 3.46 GHz @ 2.88 GHz @ 94°C @ 131W | 3.01 GHz @ 2.66 GHz @ 92°C @ 109W | 2.49 GHz @ 2.17 GHz @ 78°C @ 72W |
有趣的是，较小的16英寸笔记本提供了一个更好的短到中的极端负载性能。然而，东西在测试结束时落到了它的正确位置，我们测量到CPU的功耗为85W，而较小的设备上为72W。
现实生活中的游戏
| Nvidia RTX A3000 | GPU频率/核心温度(2分钟后) | GPU频率/核心温度(30分钟后) | GPU频率/核心温度(最大风扇) |
|---|---|---|---|
| Dell Precision 17 7770 | 1578 MHz @ 83°C @ 114W | 1568 MHz @ 84°C @ 115W | – |
| 惠普ZBook Studio G9 | 1405 MHz @ 63°C @ 80W | 1404 MHz @ 64°C @ 80W | – |
| 华硕ProArt Studiobook 16 OLED (W7600) | 1578 MHz @ 78°C @ 103W | 1589 MHz @ 79°C @ 105W | – |
不幸的是，对这台机器的冷却设置的所有补充都不能真正帮助它使用RTX A3000的TGP的全部130W。正如你所看到的，它不仅解决了115W，而且高温也没有让时钟走得太高。因此，戴尔Precision 17 7770被华硕ProArt Studionbook 16 OLED（W7600）所超越。
满负荷时的舒适度
风扇的噪音是存在的，如果不是有点大的话。奇怪的是，笔记本的键盘会变热，但我们几乎100%肯定，有一股热风穿过按键，这意味着气流是从下面排出的。通常情况下，制造商会反其道而行之，因此，风扇通过键盘吸入冷空气，在这个过程中冷却键盘。
电池
现在，我们在打开Windows更好的性能设置的情况下进行电池测试，屏幕亮度调整到120尼特，除了我们正在测试的笔记本外，所有其他程序都关闭。我们的设备配备了较大的93Wh电池，可以持续13小时6分钟的网络浏览，或10小时22分钟的视频播放。
为了模拟真实情况，我们使用自己的脚本自动浏览了70多个网站。

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.
