OnePlus 12 vs Samsung Galaxy S23 Ultra: What's the difference?

OnePlus has just revealed the OnePlus 12 in China, and it looks like a pretty impressive upgrade on the popular OnePlus 11 – but how does it compare to one of the best smartphones of 2023, the Samsung Galaxy S23 Ultra?

While the Samsung Galaxy S23 Ultra remains a tempting option in the smartphone market, the OnePlus 12 offers a slew of improvements including processing power and screen tech that could make it a very tempting option for prospective customers – if it gets an international release, anyway.

For now, here are five key differences between the OnePlus 12 and Samsung Galaxy S23 Ultra. 

The OnePlus 12 is more powerful than the Galaxy S23 Ultra

One of the key upgrades on offer from the OnePlus 12 is the new Snapdragon 8 Gen 3 chipset found within. It boasts significant upgrades over its predecessor, the Snapdragon 8 Gen 2, with OnePlus claiming a 30% boost to CPU performance and a 25% boost to GPU performance to boot. 

That’s coupled with up to a whopping 24GB of LPDDR5X RAM and up to 1TB of UFS 4.0 storage. 

There’s also the fact that the Snapdragon 8 Gen 3 supports GenAI with impressive AI processing power, but OnePlus hasn’t said anything about any GenAI-assisted features – just yet, anyway.

It’s true that the Samsung Galaxy S23 Ultra does have an overclocked version of 2023’s Snapdragon 8 Gen 2, dubbed the Snapdragon 8 Gen 2 for Galaxy, along with a healthy 8- or 12GB of RAM and up to a whopping 1TB of storage. 

However, given the year-on-year gains from Qualcomm’s chipset, we’re pretty sure that the 8 Gen 3 will have the 8 Gen 2 for Galaxy beat in most benchmarks. We’ll have to wait for a worldwide release and subsequent benchmark testing to say for sure, however! 

The Galaxy S23 Ultra has more cameras

Some regard the Samsung Galaxy S23 Ultra as the ultimate smartphone camera companion in 2023, and with a smattering of rear cameras, it’s not hard to see why. 

More specifically, the S23 Ultra has a main 200MP sensor coupled with a 12MP ultrawide, a 10MP 3x telephoto lens and a 10MP 10x periscope lens that delivers up to 100x zoom.

The OnePlus 12, on the other hand, has a trio of lenses comprised of a 50MP main sensor, 48MP ultrawide and a new 64MP periscope with 3x optical zoom, 6x lossless zoom and a maximum of 120x digital zoom. 

The lack of a dedicated 10x optical lens, like the S23 Ultra, may mean that Samsung’s option keeps its edge over the OnePlus 12 when it comes to quality zoom shots, but it’s something we’ll have to put to the test in the coming months.

The OnePlus 12 has a much brighter screen

The OnePlus 11 had a particularly impressive screen for the price point, and that looks to continue with the OnePlus 12. While the core specs are incredibly similar – a slightly larger 6.82-inch Super Fluid AMOLED display with an LTPO-enabled 120Hz refresh rate and a QHD+ resolution – the OnePlus 12 excels when it comes to brightness. 

In regular use, it can hit up to 1600nits, but that can be cranked to an incredible 4500nits when watching compatible HDR content. That’s a pretty stunning jump compared to the OnePlus 11’s 1300nits peak brightness, and gives the S23 Ultra a run for its money.

That’s because, even though much of the S23 Ultra’s display tech matches or exceeds that of the OnePlus 11 with its 6.8-inch Dynamic AMOLED 2X screen with 120Hz refresh rate, it can’t quite compete in terms of sheer brightness, capping out at a (comparatively dim, but still exceptionally bright) 1750 nits.

It may be a bit of a niche feature depending on how much HDR content you watch on your smartphone, but it’s certainly an impressive feature that could be a real win for the OnePlus 12’s display – but we’ll have to wait and see for now. 

The Samsung Galaxy S23 Ultra has an S Pen

While the OnePlus 12 might have the edge in terms of sheer display spec, one area where it can’t compete with the Galaxy S23 Ultra is in the stylus department. 

That’s because the Galaxy S23 Ultra is one of vanishingly few smartphones that ship with a dedicated stylus – more specifically, the S Pen. The accessory allows for easy doodling, note-taking and document editing with excellent handwriting-to-text conversion, and the S Pen can also double up as a remote camera shutter for group selfies. 

When it’s not in use, it’s stored in a dedicated slot within the phone’s chassis, meaning it’s readily available whenever you need it.

For comparison, the OnePlus 12, like most flagship phones, doesn’t support any high-end stylus. 

The Samsung Galaxy S23 Ultra is available to buy worldwide

The OnePlus 12 sounds like an exciting flagship, but sadly, it’s only available to buy in China – for now, anyway. Given that the OnePlus 11 was readily available to buy in the UK and Europe in 2023, it’s hopeful that we’ll see an eventual international release of OnePlus’ new flagship.

The Samsung Galaxy S23 Ultra, on the other hand, has been readily available to buy for much of 2023. In fact, you can even grab a tasty money-off deal on the flagship if you know where to look.
