So, if you're investing in a high-end graphics card for one of these external graphics boxes, just know you're probably not going to see the full potential of that GPU.Įverything kind of falls apart when we take a look at actual gaming performance, however. When connected to our test bench the RTX 2080 scores 10,970 in Time Spy, which 31% faster.
EXTERNAL GRAPHICS CARD FOR LAPTOP PC
However, when you look at what the graphics card can do when connected to a PC that can fully take advantage of it, there's no comparison. It's a small difference, but it does mean that the stronger graphics card is indeed stronger. In Time Spy, the Alienware scores 7,446 to the EGPU's 7,629.
Similarly in the hardcore Firestrike Ultra, the EGPU enables the Yoga to score a whopping 5,990 points to the 650 it gets on its own.Įven compared to the Alienware m15, the Yoga with an EGPU is looking quite nice. For instance, in Time Spy, the Lenovo Yoga C940 goes from 885 points all the way up to 7,629 when connected to the graphics box. We tested that against the laptop without an EGPU, an Alienware m15 R2 with an Intel Core i7-9750H, an Nvidia GeForce RTX 2080 and 16GB of RAM, and finally, our test bench with an AMD Ryzen 9 3900X, 32GB of RAM and the same Nvidia GeForce RTX 2080 tested in the external GPU box.Īnd, when we just look at synthetic benchmarks through 3DMark, it's looking pretty good for the external GPU. In order to test the performance 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. This is the desktop system we used for comparisonĬPU: AMD Ryzen 9 3900X (12-core, up to 4.6GHz) That means the processor isn't fast enough to keep up with the graphics card, especially in situations that tax both components. For instance, in our review for the laptop we used for testing, we found that the processor was able to score 605 points in Cinebench R15, compared to the 1,463 scored by the Intel Core i7-9700K. So right off the bat, there's a lot less bandwidth the GPU can harness, but then you also have to take into consideration that the processor is orders of magnitude slower than a desktop chip. You see, typically when you connect one of the best graphics cards to a motherboard you're able to use the full 16 PCIe lanes for the GPU - Thunderbolt 3, as magical as it is, is limited to just two. Especially when you take high-performance graphics into consideration, there's only so much an external graphics card can do. Pretty much no matter which graphics card they slotted in, they'd get much better gaming performance.īut here's the issue. This external graphics box would connect to the laptop through Thunderbolt 3 – still the only connection with enough throughput to power external graphics – and rely on the user to slot in the graphics card of their choosing.

Generally speaking, for 1080p gaming, 2GB of video memory is an adequate minimum, but 4GB is much better.Instead, Razer urged users to pick up the Razer Core V1 alongside the Razer Blade Stealth in order to boost gaming performance when at home. The amount of graphics memory (or video RAM) that your video card has onboard directly affects the resolution at which you can game smoothly, as well as the detail settings that are possible.
EXTERNAL GRAPHICS CARD FOR LAPTOP UPGRADE
In most cases, it isn't possible to upgrade a laptop's graphics card. In this regard, can I add graphics card to my laptop? Its location relates to the high-speed connection that motherboard manufacturers want between the CPU and the graphics card. When a discrete graphics card is installed, it is typically located in the expansion slot closest to the CPU.
