Samsung and Asus now both want $1,200 of your money, and only one of them ships a 3.5mm headphone jack. Spoiler: it’s neither.
That single number – twelve hundred dollars – is the real headline for the Asus ROG Phone 8 Pro and Samsung Galaxy S24 Ultra. These used to live in different worlds: ROG as the niche gaming slab, Ultra as the mainstream spec flex. Now they’re price peers, and that forces a tougher question: which one actually earns flagship money in 2024, and where do both of them drop the ball?
Design and hardware: the gamer finally wants to be normal
The ROG Phone line used to wear its gamer DNA like RGB warpaint. The ROG Phone 8 Pro tones that way down – slimmer profile, more normal camera island, less in-your-face lighting. It’s lighter than before at around 225g and finally closer to a standard flagship footprint while still being a chunky slab. You get IP68 water resistance for the first time, which is genuinely useful and long overdue.
Samsung’s Galaxy S24 Ultra sits at 232g with its familiar armored rectangle. Titanium frame, Gorilla Armor glass, and the usual note-like vibes. Ergonomically, neither is exactly comfortable, but the S24 Ultra’s flatter sides and lower center of gravity make it slightly easier to one-hand than the tall, gamer-leaning ROG.
Under the hood, both are spec monsters, but with different priorities. The ROG Phone 8 Pro runs the Snapdragon 8 Gen 3 for Galaxy? No. Asus sticks with a standard Snapdragon 8 Gen 3, paired with up to 24GB of LPDDR5X RAM and 1TB of UFS 4.0 storage in the top model. The cheaper configs give you 16GB/512GB. You also get a side-mounted USB-C port and pogo pins for accessories, which is actually useful gaming-focused hardware instead of just cosmetic flair.
The Galaxy S24 Ultra uses the Snapdragon 8 Gen 3 for Galaxy in the U.S. and some markets, and Exynos elsewhere. That overclocked chip is theoretically faster but can be more power hungry. RAM tops out at 12GB with up to 1TB storage. On paper, it’s behind the ROG’s 24GB ceiling, but realistically Android isn’t doing much with anything past 12–16GB today.
Neither phone includes a charger in the box, and neither gives you a headphone jack or microSD. For $1,200, that still feels gross, especially on the ROG side where expandable storage and wired audio would fit the target audience perfectly.
Displays, audio, and haptics: spec sheets vs real-world use
The ROG Phone 8 Pro brings a 6.78-inch 1080p-class (2400 x 1080) AMOLED with 165Hz refresh rate and up to 2,500 nits peak brightness. Touch sampling hits 720Hz, which is huge for competitive gaming. It’s flat, fast, and tuned for responsiveness, not pixel density.
Samsung goes for a 6.8-inch QHD+ Dynamic AMOLED 2X (3120 x 1440), 1–120Hz LTPO, and around 2,600 nits peak. It’s sharper, more color-accurate out of the box, and far better for reading and media at higher resolution. The S24 Ultra also handles variable refresh rate more aggressively, dropping down to 1Hz to save power.
Side by side, the S24 Ultra’s screen simply looks more premium: higher resolution, better color management, and less aggressive oversaturation. The ROG’s 165Hz is cool on a spec sheet and feels smooth in supported titles, but most Android games still cap at 60–120fps. You’re paying for overhead you rarely hit.
On audio, Asus pushes louder front-facing stereo speakers with decent low-end for a phone, plus Dirac tuning. Samsung’s stereo setup is solid but not as full. For media and gaming, the ROG has the edge in immersion. Haptics, though, are tighter and more precise on the S24 Ultra; Asus is good, but Samsung’s vibration motor feels cleaner and more controlled in typing and notifications.
Both drop the ball on wired audio support. Yes, USB-C DACs exist. No, I don’t buy the excuse on a so-called gaming phone.
Performance, thermals, and battery: raw speed vs efficiency
In benchmarks, both devices crush basically everything. Snapdragon 8 Gen 3 is a monster either way, and thermals are where the story actually gets interesting.
The ROG Phone 8 Pro leans on a vapor chamber and a new internal layout to improve heat dissipation. But the real trick remains the optional external AeroActive Cooler accessory, which can keep sustained gaming performance high for hours. Plug in the cooler and you can lock high frame rates in titles like Genshin Impact or Honkai: Star Rail with fewer throttling dips.
The Galaxy S24 Ultra doesn’t have a snap-on fan, but Samsung has expanded the vapor chamber and tuned the Snapdragon 8 Gen 3 for Galaxy fairly aggressively. Sustained performance is solid for a mainstream flagship, but if you abuse it with hour-long 3D gaming sessions, you’ll see more throttling than on a cooled ROG Phone 8 Pro.
Battery is where both stumble relative to expectations. The S24 Ultra packs a 5,000mAh cell with 45W wired and 15W wireless charging. That’s fine, but in daily use with QHD+ and mixed 120Hz usage, getting beyond a single heavy day is tough. Two days is marketing fantasy unless you’re a light user.
The ROG Phone 8 Pro actually shrinks from previous ROG models to 5,000mAh as well, down from the 6,000mAh era. You do get 65W wired charging, which is nice, but endurance isn’t the battery monster you might expect from a gaming phone. With 165Hz enabled and gaming sessions, you can kill it in a day. For a device leaning this hard into performance, that’s a step backwards.
So: both are fast, both will run basically anything, but neither crushes battery life like their marketing implies. Asus wins on sustained gaming performance with accessories; Samsung wins on cool, consistent everyday use without needing add-ons.
Cameras and software: the mainstream phone pulls away
If you care about camera performance, the Galaxy S24 Ultra wipes the floor with the ROG Phone 8 Pro. Samsung brings a 200MP main, 10MP 3x telephoto, 50MP 5x telephoto, and 12MP ultra-wide, all backed by strong computational photography and a mature camera app. You get sharp, contrast-heavy shots, great detail at 3x and 5x, and usable images out to 10x digital. Video is strong, with 4K60 across lenses and respectable stabilization.
The ROG Phone 8 Pro’s 50MP main (Sony IMX890), 13MP ultra-wide, and 32MP 3x telephoto are fine for social media, but they’re not competing with true flagship shooters. Dynamic range lags, low-light detail isn’t in the same league, and telephoto quality falls off quickly beyond 3x. Asus clearly still treats cameras as secondary to gaming, and at $1,200, that’s hard to justify.
On software, Samsung throws Android 14 with One UI 6.1 on top, plus its new Galaxy AI features – live translation, generative editing, summarization. Some of those are gimmicky; some will quietly become useful. More important: Samsung promises 7 years of OS and security updates, basically Pixel-level longevity. That’s a big deal for a phone this expensive.
Asus ships Android 14 with a lightly customized skin that lets you toggle between near-stock and ROG-style visuals. Performance features, macros, and in-game overlays are genuinely useful for power users and gamers. But Asus’s update track record is shorter and less aggressive than Samsung’s, and you’re not getting seven years of support. For a niche gaming phone, that might be acceptable. For a $1,200 device competing with mainstream flagships, it’s a weak spot.
Who should actually buy which, and who should hold off?
If you’re a hardcore mobile gamer who spends hours a day in Genshin, COD Mobile, PUBG, or emulators, the ROG Phone 8 Pro still makes the most sense. The side port, optional cooler, higher refresh, louder speakers, and in-depth performance controls add up to a clear advantage for that specific use case.
But Asus is asking mainstream flagship money while skimping on camera quality, long-term support, and creature comforts like wireless charging (yes, it’s missing). For a phone that no longer even has the huge 6,000mAh battery or truly outrageous gamer aesthetic as its calling cards, the compromises bite harder.
The Galaxy S24 Ultra is a more boring device in some ways, but boring is exactly what most people actually need: consistently good cameras, strong display, S Pen support, wireless charging, and years of software updates. For non-gamers, or even casual gamers, this is clearly the better overall phone.
The disappointment is that neither really nails the value side. $1,200 gets you serious trade-offs either way. The ROG Phone 8 Pro is a specialized tool pretending to be a mainstream flagship. The S24 Ultra is a mainstream flagship pretending it’s still okay to ship 45W charging and no charger in box while shouting about AI.
If you must pick today:
– Choose ROG Phone 8 Pro only if top-tier mobile gaming and accessory support are your absolute priority and you’re willing to accept weaker cameras and shorter support.
– Choose Galaxy S24 Ultra if you want a balanced flagship, strong camera system, and long-term updates, and you only game casually.
Everyone else? You might be better off saving a few hundred dollars on a Galaxy S23 Ultra closeout, a Pixel 8 Pro at $999, or a ROG Phone 7 Ultimate if you can find one. The spec monsters have never been louder, but the value argument has rarely been weaker.
