At its Unpacked occasion final week, Samsung made some daring guarantees concerning the efficiency of its Galaxy S23 collection telephones. The corporate made fairly some ballyhoo about the marginally quicker trim of Qualcomm’s Snapdragon 8 Gen chip that’s unique to those telephones, touting a 41% acquire in graphics efficiency.
Samsung proclaimed that “probably the most important enchancment is the optimized GPU which is roughly 41% quicker,” including that “the GPU structure has been enhanced for efficiency and effectivity.” Nonetheless, the extra important declare was in regards to the reworked vapor chamber cooling system, which is fitted inside all three telephones and “is now bigger than earlier than.”
Leaker Ice Universe additionally shared schematics of the larger vapor chamber structure fitted contained in the Galaxy S23 trio, which replaces the thermal system on the coronary heart of the Galaxy S22. Above is the official illustration — purportedly depicting the vanilla S23 or its Plus trim — on the Unpacked stage.
Why go large?
Now, a bigger vapor chamber system is required contained in the Galaxy S23 collection telephones, as a result of the CPU cores of its customized chip tick at the next frequency. Plus, the GPU comes with a particular ray tracing module for enhanced mild and shadow rendering in video games.
Right here’s how Samsung imagines the distinction created by ray tracing in cellular video games:

Quicker CPU cores, a beefier GPU, and an added ray-tracing module would imply extra warmth is generated inside that cup and steel chassis. One of the simplest ways to deal with that additional warmth can be to supply extra vertical house beneath the hood with a view to preserve issues from getting toasty. That didn’t occur.
When you evaluate the size of the Galaxy S23 triad towards their respective Galaxy S22 collection counterparts, you’ll discover that the thickness stays the identical. For sure, a greater thermal administration system was a necessity, and Samsung’s engineers seem to have met that want.
The corporate is hyping its newest flagships with claims of providing “probably the most highly effective gaming expertise but.” And because of the bigger vapor chamber cooling system, all that gaming potential will supposedly be realized with out making the cellphone breathe hearth out of its vents.

The truth is, the launch occasion’s host promised “a PC-like gaming expertise.” Now, I don’t personally agree with that analogy, however an environment friendly vapor chamber cooling system does make a tangible distinction, particularly throughout demanding duties like taking part in high-end video games or recording 4K movies.
Samsung has performed a extremely good job with its vapor chamber cooling options previously, regardless that the corporate has at all times been modest in regards to the gaming chops of its camera-centric flagships. I extensively examined the Galaxy S22 Extremely towards the OnePlus 10 Professional final yr and located the Samsung cellphone performing noticeably higher at every thing from gaming to artificial benchmarks.
I’m anticipating nothing much less from the Galaxy S23 Extremely this yr. Nonetheless, I’m extra excited for the smaller Galaxy S23, which has a considerably tighter inner house for warmth dissipation — but supposedly doesn’t make any compromises when it comes to uncooked efficiency in comparison with its Extremely sibling.

After all, it’s difficult to maintain the smaller mannequin operating as cool as its Extremely sibling beneath the identical type of load, however it might be attention-grabbing to see if Samsung’s engineers have really managed to perform the unthinkable.
Samsung’s atoning for the sins of its previous
Once I examined the Galaxy S22 final yr, heating was one among my largest considerations. Be it gaming, video seize, and even charging, the compact cellphone warmed up relatively shortly. A part of that downside will also be attributed to the Snapdragon 8 Gen 1, which had some well-known heating woes.
However there was one other performance-related scandal that quickly exploded right into a full-fledged lawsuit in Samsung’s house market. Final yr, it was found that Samsung was deliberately slowing down its Galaxy S22 flagships with out correct disclosure.
On the coronary heart of the problem was its Sport Optimization Service — an in-house app that discreetly ran within the background to optimize the cellphone’s efficiency and battery life, whereas additionally conserving the rising inner temperature in verify. Some artificial checks discovered that the Galaxy S22 collection telephones have been solely delivering half the firepower that the processor was able to when the GOS system was lively within the background.
Samsung ultimately accepted that its cellphone did have interaction in throttling for hundreds of apps, all within the title of regulating the temperature and guaranteeing constant efficiency. The corporate quickly added a efficiency mode to its Sport Booster app, which allowed customers to faucet into the processor’s full potential.

With the Galaxy S23, Samsung not solely has to keep away from an analogous shady stunt, however it additionally must ship on its promise of a PC-like gaming expertise. The Snapdragon 8 Gen 2 inside the brand new newest Samsung flagships and its ray tracing chops will fairly actually blow off some steam.
It might be attention-grabbing to see how the bigger vapor chamber cooling system goes to maintain issues chill with out compromising on the uncooked efficiency. The Digital Developments crew has already began testing the Galaxy S23 collection telephones, and the findings shall be out quickly.
We shall be placing Samsung’s claims to the check with intensive gaming checks and assess whether or not the improved vapor chamber cooling system really yields any generation-over-generation features. Keep tuned for the evaluation coming quickly. In the meantime, try this wonderful explainer of how a vapor chamber cooling system works inside a cellphone, full with tons of nerdy stats.
