Key Differences
-
The vivo X300 Ultra has a higher-resolution 200 MP main camera
Among all the differences on this page, 200 MP against 48 MP is one of the most meaningful, and it favors the vivo X300 Ultra. The vivo X300 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer.
-
The vivo X300 Ultra has a dedicated 200 MP telephoto camera
The iPhone 17 Pro Max gives up a lot on telephoto camera: 48 MP, compared with 200 MP on the vivo X300 Ultra. Telephoto lenses earn their keep at concerts, school events and portraits: anywhere you can’t simply walk closer.
-
The vivo X300 Ultra has a 144 Hz display instead of 120 Hz
On refresh rate, the vivo X300 Ultra edges out the iPhone 17 Pro Max, 144 Hz to 120 Hz. Smoother motion is one of the most visible display upgrades, and adaptive high-refresh panels can slow down on static content to save power.
-

Few buyers will miss this one. The iPhone 17 Pro Max brings 2 TB to the table; the vivo X300 Ultra brings 1 TB. Heavy video shooters and people with large offline libraries benefit from the iPhone 17 Pro Max’s bigger maximum.
-
The vivo X300 Ultra has a sharper 50 MP selfie camera
When it comes to front camera, the vivo X300 Ultra wins comfortably with 50 MP against 18 MP. If you mainly use the front camera for calls, the gap is minor; if you post selfies often, the vivo X300 Ultra’s extra resolution helps.

Display
vivo X300 Ultra leads
The vivo X300 Ultra has the slight upper hand on display. The vivo X300 Ultra has the edge with a 144 Hz display instead of 120 Hz. A higher refresh rate makes scrolling, animations and games look smoother. Once you’re used to it, a lower-rate screen can feel sluggish by comparison. Anyone shopping mainly on display should start with the vivo X300 Ultra.
Refresh rate
vivo X300 Ultra: 144 Hz iPhone 17 Pro Max: 120 Hz You notice refresh rate every time you scroll a feed or a web page, which is why the vivo X300 Ultra feels more fluid in everyday use.
Performance
Too close to call
Neither pulls ahead on performance; the numbers are close throughout. Bottom line for performance: it’s a wash.
CPU cores
vivo X300 Ultra: 8 iPhone 17 Pro Max: 6 Phone chips mix large and small cores, so a different count mostly reflects a different design rather than a clear speed gap.
Memory & Storage
iPhone 17 Pro Max leads
The memory & storage numbers lean toward the iPhone 17 Pro Max, not dramatically but consistently. The iPhone 17 Pro Max pulls ahead with a bigger top storage option. Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it. Prioritize memory & storage, and the iPhone 17 Pro Max is where you should land.
Max storage
vivo X300 Ultra: 1 TB iPhone 17 Pro Max: 2 TB The top storage option only matters if you plan to buy a high-capacity version, but it caps how much you can ever keep on the phone.
Camera
vivo X300 Ultra leads
This is one of the vivo X300 Ultra’s strongest areas. On camera, the iPhone 17 Pro Max falls well short. The vivo X300 Ultra takes this one with a higher-resolution 200 MP main camera. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos. If camera is your priority, the vivo X300 Ultra is the phone to pick.
Main camera
vivo X300 Ultra: 200 MP iPhone 17 Pro Max: 48 MP More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much.
Telephoto camera
vivo X300 Ultra: 200 MP iPhone 17 Pro Max: 48 MP A dedicated telephoto camera captures distant subjects and portraits without heavy cropping, which keeps detail intact.
Battery & Charging
vivo X300 Ultra leads
Slight edge to the vivo X300 Ultra on battery & charging. Most buyers could live happily with either. Point to the vivo X300 Ultra for faster 40 W wireless charging. Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience. Weighing only battery & charging, the vivo X300 Ultra comes out ahead.
Wireless charging
vivo X300 Ultra: 40 W iPhone 17 Pro Max: 25 W Faster wireless charging makes a pad or stand more practical as your main way to top up.
