Increasingly more we’re seeing skinny and lightweight laptops and Ultrabooks which might be being marketed as each gaming and productiveness machines, on the promise you could connect exterior graphics to spice up energy if you want it at house.
The gross sales pitch is that this: you possibly can have a skinny and lightweight Ultrabook just like the Lenovo Yoga C940 – which we used for testing – and join an EGPU through Thunderbolt Three to show it right into a gaming or productiveness gadget at house. The thought is that you’ll leverage the facility of a full desktop graphics card like an Nvidia GeForce RTX 2080 in apps like Adobe Premiere or in video games, with out having to accept a bulkier gaming laptop computer.
Nonetheless, it would not fairly work that manner. Whereas an exterior GPU will definitely increase efficiency over the built-in graphics that loads of gaming laptops provide, it is typically not sufficient to justify the massively inflated price that one in all these cumbersome bins essentially brings.
So we determined to check simply how a lot further efficiency you possibly can anticipate from one in all these graphics bins, and whether or not or not you need to simply go for a full gaming laptop computer as a substitute.
First, a little bit of background
The unique Razer Blade Stealth launched manner again in 2016, together with the Razer Core V1. The laptop computer was marketed as a skinny and lightweight “gaming laptop computer”, although it used an Intel U-series processor with built-in graphics – not one thing particularly nice for gaming.
As an alternative, Razer urged customers to choose up the Razer Core V1 alongside the Razer Blade Stealth as a way to increase gaming efficiency when at house.
This exterior graphics field would hook up with the laptop computer by means of Thunderbolt 3 – nonetheless the one reference to sufficient throughput to energy exterior graphics – and depend on the consumer to fit within the graphics card of their selecting. Just about regardless of which graphics card they slotted in, they’d get a lot better gaming efficiency.
However this is the difficulty. Particularly if you take high-performance graphics into consideration, there’s solely a lot an exterior graphics card can do. You see, sometimes if you join one of many finest graphics playing cards to a motherboard you are ready to make use of the complete 16 PCIe lanes for the GPU – Thunderbolt 3, as magical as it’s, is restricted to simply two.
So proper off the bat, there’s loads much less bandwidth the GPU can harness, however then you definately additionally should consider that the processor is orders of magnitude slower than a desktop chip. For example, in our evaluate for the laptop computer we used for testing, we discovered that the processor was capable of rating 605 factors in Cinebench R15, in comparison with the 1,463 scored by the Intel Core i7-9700Ok. Meaning the processor is not quick sufficient to maintain up with the graphics card, particularly in conditions that tax each elements.

Let’s discuss efficiency
Take a look at system specs
That is the desktop system we used for comparability
CPU: AMD Ryzen 9 3900X (12-core, as much as 4.6GHz)
CPU Cooler: NZXT Kraken X62
RAM: 32GB HyperX Predator RGB @ 3,000MHz
GPU: Nvidia GeForce RTX 2080
Motherboard: X570 Aorus Grasp
SSD: Samsung 860 QVO 1TB
Energy Provide: Phanteks Revolt X 1200
Case: Praxis Wetbench
As a way to take a look at the efficiency of an Nvidia GeForce RTX 2080 on an EGPU, we paired it with a Lenovo Yoga C940 with an Intel Core i7-1065G7, 12GB of RAM and a 512GB NVMe SSD.
We examined that in opposition to the laptop computer with out an EGPU, an Alienware m15 R2 with an Intel Core i7-9750H, an Nvidia GeForce RTX 2080 and 16GB of RAM, and at last, our take a look at bench with an AMD Ryzen 9 3900X, 32GB of RAM and the identical Nvidia GeForce RTX 2080 examined within the exterior GPU field.
And, after we simply have a look at artificial benchmarks by means of 3DMark, it is trying fairly good for the exterior GPU. For example, in Time Spy, the Lenovo Yoga C940 goes from 885 factors all the way in which as much as 7,629 when linked to the graphics field. Equally within the hardcore Firestrike Extremely, the EGPU permits the Yoga to attain a whopping 5,990 factors to the 650 it will get by itself.
Even in comparison with the Alienware m15, the Yoga with an EGPU is trying fairly good. In Time Spy, the Alienware scores 7,446 to the EGPU’s 7,629. It is a small distinction, nevertheless it does imply that the stronger graphics card is certainly stronger.
Nonetheless, if you have a look at what the graphics card can do when linked to a PC that may totally benefit from it, there isn’t any comparability. When linked to our take a look at bench the RTX 2080 scores 10,970 in Time Spy, which 31% quicker. So, in the event you’re investing in a high-end graphics card for one in all these exterior graphics bins, simply know you are most likely not going to see the complete potential of that GPU.
Every part form of falls aside after we check out precise gaming efficiency, nonetheless. We examined this setup in Metro Exodus, which we admit is an enormous ask for even the very best gaming laptops. Nonetheless, whereas the Lenovo Yoga C940 does bounce up from 6 fps to 23 fps when hooked up to the EGPU, the Alienware m15 is almost twice as quick at 44 fps. Then, there’s our take a look at bench which jumps all the way in which as much as 63 fps.
That is solely as a result of the processor on this laptop computer simply is not as much as snuff for high-end gaming. If you happen to’re dead-set on choosing up a laptop computer with an exterior graphics resolution, simply understand that the fact shouldn’t be fairly as rosy because it may appear.
Ought to I purchase an EGPU?
One factor is abundantly clear by means of our testing, particularly in terms of artificial benchmarks: you actually are getting a lot larger efficiency. If you happen to’re a touring creator that desires a brilliant skinny and lightweight laptop computer to take to conferences, after which connect it to a EGPU to get hardcore work completed when again at a desk, it is truthfully an superior resolution.
Nonetheless, in the event you’re trying to play the finest PC video games, it merely is not a fantastic resolution. Now, the Lenovo Yoga C940, the Razer Core X and an Nvidia GeForce RTX 2080 will run you about $2,299 (about £1,760, AU$3,400), the place the Alienware m15 will run a bit extra at $2,499 (£2,499, AU$4,419). However for that small bump in worth, you are getting practically double the efficiency in precise video games.
And, if you wish to recreation at house and have a skinny and lightweight laptop computer to hold round, there’s a simple resolution: decide up among the best Chromebooks and name it a day. You’ll be able to construct a PC that may outperform this setup for practically half the worth, after which spend the remaining on a pleasant little transportable laptop computer that will not break the financial institution. That is the answer that we use at house, and it is one we wholeheartedly suggest for aspiring PC players on the market.
Do not buy into the hype of gaming laptops that may’t truly play video games – the efficiency numbers simply aren’t there.
