DESIGN
When you put these two together side by side, the 7550 is larger in size. The 7550 is about just one centimeter larger than the 5550. Thickness-wise, the 5550 is nearly the half-thickness of the 7550, so the 5550 does an amazing job.
Weight-wise, the 5550 weighs about 1.86 kilos and as for the 7550 you’re looking at 2.6 kilos, so that’s around about 800 grams more.
With the precision 5550, it comes with a 130-watt power adapter. This power adapter charges the Precision 5550 through a USB-C port.
With the Precision 7550, it comes with a 180-watt power adapter and that actually is a barrel style. It’s about a quarter of the size with the 130-watt power adapter compared to the 180-watt power adapter.
With the Precision 5550, you’re looking for the weight of a laptop plus the actual power adapter is 2.3 kilos. With the 7550, the total weight of the unit plus the power adapter is 3.3 kilos.
So, that’s a one-kilo difference between this 5550 and the 7550. So, if you’re doing a lot of traveling, especially on planes, the 5550 does look a lot nicer.
DISPLAY
As for the display, there’s a big difference there as well. With the Precision 7550, you’ve got your normal aspect ratio of 16 by 9 whereas this Precision 5550 has got a gorgeous screen that has an aspect ratio of 16 by 10.
So, you can actually fit more on the display and the Precision 5550 has more thinner bezel as well. So display-wise, 5550 looks a lot nicer. For configuring, they both are very similar.
You can get full HD with touch and non-touch and there’s also a 4K version of these two computers as well.
BATTERY
In terms of battery life, you’ll find the Precision 5550 has a little bit longer battery life compared to the 7550. Looking about a quarter more, you’re looking for about an hour to two hours a lot more than the 7550 and this is not under the ultra-performance mode.
They both are very similar when you put these two computers ultra-performance and you’re just running it on 100% load, they both will be just under an hour.
The difference is once you get into the better battery life modes that’s where the difference becomes, you’ll see an hour or two on the Precision 5550 for the battery life.
The 7550 doesn’t have a longer battery life compared to the 5550, maybe it’s because of cooling. They both running i7 with the Quadro T1000. They both have an express charging system.
WHICH TO BUY?
I definitely feel that the Precision 5550 feels more like a laptop where you can actually transport and work around because of the lightness. Whereas, the Precision 7550 is like more closer to the actual desktop replacement. Definitely, the Precision 7550 weighs a lot than the 5550 but it is a closer desktop replacement.
