Realme's pitch for the P4s 5G sounds almost too good for the price: a dedicated AI chip that pushes gameplay to 144FPS on a phone that starts well under half of what an actual gaming flagship costs. It's the kind of claim that gets shared in every WhatsApp gaming group within a day of launch. But scroll far enough down Realme's own India product page, and you'll find a line that quietly undercuts the headline number. Before you decide whether the Realme P4s's AI gaming chip is worth paying extra for, it's worth understanding exactly what that chip is doing, and what Realme itself admits about the number it's built around.

What Does an "AI Gaming Chip" Actually Do in a Phone?
"AI gaming chip" is marketing language for a job that's fairly mechanical underneath. On the Realme P4s, the main MediaTek Dimensity 7400 Ultra chipset (built on a 4nm process, paired with a Mali-G615 MC2 GPU) does the actual work of running the game: physics, logic, and rendering each frame from scratch. The separate Hyper Vision+ AI chip sits alongside it and does something different. It takes the frames the GPU has already rendered and generates new synthetic frames in between them, upscales resolution where needed, and tweaks things like HDR tone mapping on the fly.
That's frame interpolation, and if you've followed PC gaming at all, it's the same basic idea behind Nvidia's DLSS frame generation or AMD's FSR, just running on a phone instead of a graphics card. It's not extra rendering horsepower. It's a chip whose entire job is to make a lower frame rate look smoother without the GPU actually working harder to hit that number.

| Realme's own product-page fine print says the 144FPS gameplay figure is achieved through dedicated-chip frame interpolation and non-native game rendering. |
We ran into a version of this same gap between marketed AI hardware and what it does in daily use when we looked at NPUs in laptops sold for local AI work. The dedicated chip exists on paper, but what it's actually doing while you use the machine tells a very different story than the spec sheet. The Realme P4s is the same pattern moved from a laptop's NPU to a phone's gaming chip.
What Realme's own product page says:
Buried in the fine print under the P4s's 144FPS gaming claim on realme.com/in/realme-p4s-5g is this line: "144FPS gameplay achieved through dedicated chip frame interpolation, non-native game rendering." That's Realme, in its own words, confirming the headline number isn't the GPU natively hitting 144 frames per second. It's generated frames filling the gaps.
Is Frame Interpolation the Same as Higher Native FPS?
No, and this is the part that matters most if you're weighing the P4s specifically because of the FPS number on the box. Frame interpolation works by looking at two frames the GPU has genuinely rendered and generating one or more synthetic frames to insert between them, smoothing out motion on screen. It doesn't reduce input lag (the phone still responds to your taps only as fast as the real rendering pipeline allows), and it doesn't add real detail or accuracy; it's a visual smoothing trick layered on top.
 |
| Native FPS requires the GPU to render each frame; interpolation inserts AI-generated frames between rendered frames to make motion appear smoother. |
It also tends to work better in some situations than others. Digit's hands-on testing of the Realme P4 Pro, which uses the same Hyper Vision approach without the "+", found that gameplay stayed smooth most of the time but noticeably dropped back toward its native refresh ceiling during fast, chaotic scenes, exactly the kind of gunfights BGMI throws at you constantly. That's the honest tradeoff with interpolation: it looks great in a controlled demo and gets less reliable the more unpredictable the on-screen action gets.
If you want the deeper mechanics of why a single big FPS number on a spec sheet rarely tells the whole story, whether that number is native or interpolated, we broke down why 1% lows and frame time stutter matter more than peak FPS in PC gaming, and the same logic applies here.
Realme P4s's Dual-Chip Setup, Explained
Splitting the work like this is the whole idea behind the "Realme P4s dual chip" design. The Dimensity 7400 Ultra handles everyday computing, app performance, and the actual game logic and rendering. The Hyper Vision+ AI chip runs alongside it purely for visual post-processing: pushing interpolated frame rates up to 144FPS, running a separate "stabilisation" layer aimed at a steadier 90FPS, and handling AI-based resolution upscaling.

| The P4s separates game rendering on the main SoC from frame interpolation and other visual processing on the dedicated Hyper Vision+ chip. |
Realme's own lab testing (self-reported, not independently benchmarked) claims an AnTuTu score of roughly 1,039,849 for the combined package. That's a respectable number for this price bracket on paper, but AnTuTu scores measure general system performance rather than sustained real-game frame rates, so it doesn't directly confirm anything about the interpolation claims specifically.
Does the Hyper Vision+ Chip Actually Make BGMI Run Better?
Realme's specific BGMI claims for the P4s are a "stabilised" 90FPS mode alongside the interpolated 144FPS mode, plus a claimed 16% reduction in power draw while running that stable 90FPS compared to similar phones without the dedicated chip. Both figures come from Realme's own internal lab testing.
Worth flagging before you take these numbers at face value:
As of writing, no independent Indian reviewer appears to have published a fully benchmarked review of the P4s with real, tested BGMI frame rate and stutter numbers. Digit's early hands-on with the device explicitly said proper benchmarking would wait for its complete review. Until that lands, treat the 90FPS stability claim and the 16% power figure as Realme's numbers, not third-party verified ones.
 |
| Real-world BGMI performance matters more than the advertised peak FPS figure, especially when frame interpolation is involved. |
For a rough real-world comparison point, 91mobiles' own lab testing of the standard Realme P4 (a cheaper phone in the same series, using the earlier Hyper Vision AI chip) measured an average of 59.1FPS in BGMI at Medium+High graphics settings over a 30-minute match, well below any of the marketed peak numbers for that device too. That's not a direct prediction for the P4s, but it's a useful reminder that "up to" figures on a spec sheet and sustained numbers during an actual match are rarely the same thing.
If your phone is already struggling with BGMI and a Realme P4s isn't in the budget right now, we've got a separate guide on squeezing better BGMI performance out of a low-end phone without buying a new one.
Does a Dual-Chip Setup Actually Reduce Gaming Heat?
The P4s pairs its chips with a 7,000mm² vapour chamber cooling system, and according to some outlets, an additional 13,624mm² graphite layer with a thicker sheet than earlier P-series phones. On paper, offloading visual processing to a second chip could, in theory, mean the main SoC isn't working flat out on its own during a game, which can help with sustained heat. But a second chip is also more total silicon drawing power, so the net thermal outcome depends heavily on how well that cooling system actually manages both chips together, not just on the fact that there are two of them.
The phone's IP66, IP68, and IP69 ratings are about dust and water resistance, not heat management, and it's worth not conflating the two even though Realme lists them together in its marketing copy. As with the FPS claims, no independent thermal camera testing for the P4s specifically was available at the time of writing, so this is another area where the full reviews (once they land) will matter more than the launch specs.

Not Just the P4s: This Is Realme's Whole P-Series Playbook Now
It's worth being clear that the P4s isn't introducing something brand new to the lineup. The cheaper Realme P4 (from around ₹18,499) and the Realme P4 Pro (from around ₹24,999 to ₹28,999 depending on the sale) already ship with a "Hyper Vision AI Chip" (no "+"), doing essentially the same frame interpolation job at a lower price. Digit's own review of the P4 Pro noted the same pattern: smooth-looking BGMI gameplay most of the time, with dips back toward native refresh in intense scenes, because it's the same underlying interpolation approach, just under a different name.
That matters for how you read theP4'ss marketing. This isn't a one-off feature built specifically for this phone; it's becoming Realme's standard way of selling a 144Hz display across an entire price range, and it's likely to show up in future phones too. Once you recognise the pattern, "AI gaming chip" starts reading less like a unique selling point and more like a category-wide marketing trend worth watching across brands, not just from Realme.
- Genuinely smoother-looking motion in supported games, even though the frames aren't natively rendered
- 144Hz display plus a dedicated visual-processing chip is still rare below ₹40,000
- Strong all-round hardware outside the AI chip debate: 8,000mAh battery, 80W charging, IP66/68/69 rating
- Three years of OS updates and four years of security patches is solid for this price band
- Offloading visual post-processing to a second chip could help keep the main SoC freer during gameplay, at least in theory
- Realme's own fine print confirms the 144FPS headline number is interpolated, not native.
- No independent Indian outlet has published tested BGMI frame rate or stutter numbers for the P4s as of writing.g
- The 16% power-saving figure and AnTuTu score are Realme Lab claims, not third-party verified
- Frame interpolation can introduce visible smoothing artifacts during fast-motion scenes like BGMI gunfights
- The same core Hyper Vision approach already exists on the cheaper P4 and P4 Pro, so the P4s isn't offering something entirely new for the extra money.
Is a 144Hz Display Worth It If Games Don't Hit 144fps Natively?
Partly. A 144Hz panel makes scrolling, animations, and general UI feel noticeably smoother regardless of what any individual game hits, so it's not a wasted spec even before you factor in gaming. But for competitive titles specifically, BGMI's official frame rate cap on most Android devices tops out well below 144fps natively, and COD Mobile has its own device-tier-based caps too. So the 144Hz number on the P4s's box is really serving two different purposes: genuine everyday smoothness, and a marketing hook for the interpolated gaming mode.
This is a similar situation to a marketed graphics feature that looks great in a spec comparison but doesn't always translate into real-world value once you dig in. We ran into the same pattern looking at ray tracing on budget GPUs, where the feature existing on paper and the feature being worth turning on in practice turned out to be two different questions entirely.
Realme P4s Price in India and What Else ₹30,000 to ₹42,000 Buys You
At ₹34,999 to ₹41,999 before offers (₹31,999 to ₹38,999 with the current ₹3,000 bank offer), the P4s sits in an increasingly crowded bracket. The iQOO Z11 5G starts around ₹34,999 and runs on MediaTek's Dimensity 7500 Turbo, generally considered stronger raw silicon than the Dimensity 7400 Ultra, without leaning on a second chip's interpolation trick to sell its gaming credentials. The Vivo T5 Pro, priced roughly in the ₹35,000 to ₹39,000 range depending on the variant and ongoing offers, instead makes its case with a massive 9,020mAh battery.
If you're specifically hunting for the best gaming phone under ₹30,000 with strong cooling and FPS numbers, it's worth knowing this bracket has genuinely shifted upward this year. Most of the phones making real gaming claims with dedicated cooling hardware, including the P4s itself, now start closer to ₹35,000 once you account for realistic effective pricing, so treat ₹30,000 as the entry point for compromises rather than the segment where these features arrive uncompromised.
The Verdict: Should the AI Gaming Chip Sway Your Decision?
Here's the honest read. If you're choosing the Realme P4s specifically because you believe it natively renders 144 frames per second in BGMI, mat lo, that's not what's happening, and Realme's own fine print says so. The dedicated chip is doing frame interpolation, and until an independent Indian reviewer publishes tested numbers, the stability and power-saving claims around it remain Realme's word, not verified fact.
That said, the P4s isn't a bad phone once you separate it from that one marketing line. The battery, charging speed, display quality, and durability ratings are all genuinely strong for ₹35,000 to ₹42,000 effective pricing. If those fundamentals matter more to you than a specific FPS number, and you go in expecting interpolated smoothness rather than a native performance leap, it's a reasonable phone to shortlist alongside the iQOO Z11 and Vivo T5 Pro in this bracket.
Frequently Asked Questions
What does an AI chip actually do in a gaming phone?
In phones like the Realme P4s, the dedicated AI chip doesn't do the actual game rendering. It takes frames the main GPU has already produced and generates additional synthetic frames between them (frame interpolation), along with upscaling and HDR enhancement, to make gameplay look smoother without the GPU rendering that many frames natively.
Does the Realme P4s's Hyper Vision+ chip really make BGMI run better?
Realme claims a stabilised 90FPS mode and a 16% power draw reduction in BGMI, but these figures come from Realme's own internal lab testing. As of writing, no independent Indian outlet has published a full tested review with real BGMI frame rate numbers for the P4s, so these claims should be treated as manufacturer figures until third-party benchmarks confirm them.
Is frame interpolation the same as higher native FPS?
No. Frame interpolation generates synthetic frames between two frames the GPU has genuinely rendered, which smooths motion visually but doesn't reduce input lag or add real rendering power. Native FPS means the GPU is actually computing every frame from scratch at that rate.
Does a dual-chip setup actually reduce gaming heat?
It can help in theory, since offloading visual processing to a second chip may reduce load on the main SoC. But a second chip also draws its own power, so the real outcome depends on how well the phone's cooling system (a 7,000mm² vapour chamber on the P4s) manages both chips together. No independent thermal testing for the P4s was available at the time of writing.
Is a 144Hz display worth it for BGMI and COD Mobile if the games don't hit 144fps natively?
Partly. A 144Hz panel improves everyday smoothness (scrolling, animations, UI) regardless of in-game frame rates, so it's not wasted. But since BGMI and COD Mobile cap native frame rates well below 144fps on most Android devices, the 144Hz gaming claim mostly applies to interpolated modes rather than a genuine competitive edge.
