Huawei's phone has a wraparound display.
The most noticeable discrepancy between these two devices is in the way that their screens fold.
The screen on Huawei's Mate X wraps around the device, resulting in a paper-like crease down the center that's barely visible when opened.
Samsung's phone opens like a book.
Samsung's Galaxy Fold features a hinge that gives it a clamshell form factor. When unfolded, it opens up like a book to reveal a larger tablet screen on the inside of the device.
Huawei's device features a larger screen than Samsung's in both phone and tablet mode.
The Huawei Mate X includes a 6.6-inch screen on the front of the device and a 6.38-inch display on the back of the phone when folded. When unfolded, these displays combine to form an 8-inch tablet display.
The Samsung Galaxy Fold, by comparison, has a 4.6-inch phone screen and a 7.3-inch tablet screen.
Huawei's phone also has a higher price to match that bigger display.
The Huawei Mate X will cost $2,600 while Samsung's Galaxy Fold starts at $1,980.
There are also other design differences between the two phones other than their display size and folding mechanism.
Huawei's Mate X features a grip along the side that's noticeably thicker than the rest of the device — it's where the phone's cameras and charging port are located.
The cameras on the Galaxy Fold are located on the back of the device, similar to the camera placement on more traditional smartphones.
Compared to the Galaxy Fold, the Mate X also appears to have a much thinner border around its display when in phone mode.
Samsung's Galaxy Fold has more memory than Huawei's foldable phone.
If Samsung is going to give you double the screen, it's going to provide double the memory to match. The Galaxy Fold includes 12GB of RAM, offering twice as much memory as the company's entry-level flagship, the Galaxy S10e. Samsung is positioning the Fold as a powerhouse that can read and write data faster than any other phone or tablet.
The Huawei Mate X, by comparison, includes 8GB of RAM, the same amount as Samsung's Galaxy S10 and Galaxy S10+.
Samsung's phone also has more cameras than Huawei's.
As is the case with previous Huawei devices, the Mate X uses Leica technology in its cameras — which include a 40-megapixel wide angle lens, a 16-megapixel ultra-wide-angle lens, and an 8-megapixel telephoto lens.
Samsung's Galaxy Fold has six cameras, which include two 10-megapixel selfie cameras, an 8-megapixel RGB depth camera, a 12-megapixel telephoto camera, a 12-megapixel wide-angle camera, and a 6-megapixel ultra-wide-angle camera.
But it's impossible to tell which phone snaps superior photos without actually using them, as there are many factors other than the sheer number of cameras or megapixels that contribute to image quality.
Huawei's phone has a larger battery than Samsung's.
Huawei's Mate X has a 4,500 mAh battery, while Samsung's Galaxy Fold as a 4,380 mAh battery.
But as is the case with camera quality, size and capacity alone isn't enough to determine which phone will offer better battery life in everyday use, as there are a variety of elements that can impact power consumption.
Samsung's phone will be released sooner than Huawei's.
Samsung announced that the Galaxy Fold will launch on April 26, while Huawei's foldable Mate X is slated to be released in the middle of 2019.
Although Samsung's phone is launching in roughly two months, it did not allow press to use the device after its Unpacked press conference on February 20.
