We made iQOO 15 go through various hardcore challenges, and the Results are amazing !! 

In our comprehensive performance evaluation of the iQOO 15, we pushed the Snapdragon 8 Elite gen 5 chipset to its absolute limits across a series of industry-standard benchmarks. By conducting extensive AnTuTu, Geekbench CPU/GPU, and 3DMark stress tests, we aimed to quantify the raw power and thermal efficiency of this flagship contender. The results provide a definitive look at how iQOO's aggressive hardware tuning translates into real-world computational and graphical dominance.

*We have used a Beta testing device for the test. The test was done on 18th December between 7-11 pm. While we started testing a score, the device was not heated. But after testing AnTuTu and 3d Mark score, the device was heated. Room Temperature - around 20 degree celcius.

Geekbench CPU score.

The iQOO 15 delivers a dominant CPU performance, achieving a single-core score and multicore score. This is driven by its Snapdragon 8 Elite (Gen 5) chipset, which utilizes two massive 4.61GHz Prime cores and six perfomence cores clocked at 3.62 GHz.

Our Scores:

SINGLE CORE - 3578.

MULTI CORE - 10369.  

Geekbench uses real-world workloads to help users understand how a device will actually feel in daily use.

Geekbench GPU score.

The iQOO 15, powered by the flagship Snapdragon 8 Elite Gen 5, achieves exceptional GPU performance with its Adreno 840 graphics processor. For reference, its overall graphical power is reflected in AnTuTu GPU sub-scores that exceed 1.4 million, solidifying its position as one of the fastest gaming smartphones of 2025.

Our Scores:

AnTuTu GPU  - 1,421,581

Geekbench GPU - 23,540

(It specifically measures the General-Purpose GPU (GPGPU) capabilities of a chip)

3D mark stress test

In the 3DMark Wild Life Extreme Stress Test, the iQOO 15 achieves a formidable "Best Loop" score , highlighting the raw power of the Snapdragon 8 Elite Gen 5 and its Adreno 840 GPU. To manage this intensity, the device utilises a massive 8,000mm² vapour chamber that helps maintain stability between 60% and 80% during prolonged 20-minute sessions. While its aggressive performance tuning can lead to moderate thermal throttling under extreme synthetic loads, it consistently outpaces most competitors in peak graphical output and ray-tracing tasks.

Our Scores : 

Wild Life Extreme Stress Test - 

• Highest Loop Score - 7174
• Lowest Loop Score - 4550
• Stability- 63.4%

Solar Bay (Ray Tracing)

• Highest Loop Score - 13394
• Lowest Loop Score - 7495
• Stability- 56%

(The 3DMark Stress Test is measured to evaluate how a smartphone handles sustained, heavy workloads over time, rather than just in short bursts)

AnTuTu Score.

The iQOO 15 delivers a monumental performance on AnTuTu v11, powered by the Snapdragon 8 Elite Gen 5. This score is bolstered by a massive GPU sub-score of over 1.41 million, ranking it as one of the most powerful gaming smartphones currently available. To sustain these high numbers, the device employs an 8,000mm² vapor chamber and the dedicated Q3 SuperComputing chip, ensuring it remains at the top of global performance charts while managing heat effectively.

Our score:

Total AnTuTu Score - 3,910,757.

• CPU- 1,181,944
• GPU-1,421,581
• MEM-426'500
• UX-880,732

CPU Throttle Test

A CPU Throttle Test is a diagnostic procedure used to determine if a processor is reducing its performance (clock speed) to protect itself from damage—usually due to excessive heat or power consumption.

Essentially, the test pushes the CPU to its maximum capacity for a sustained period to see if the cooling system can keep up. If the cooling fails to dissipate heat fast enough, the CPU "throttles" (slows down), and the test records this performance dip.

Our Scores:

Max. gips score - 451325

Min. gips score - 406349

Stability - 90%

Ultimately, the iQOO 15 has proven itself to be a true performance powerhouse by maintaining exceptional stability even under the most demanding hardcore challenges. Its advanced cooling architecture effectively neutralised thermal throttling, ensuring that peak clock speeds remained consistent during sustained workloads. Whether it’s high-frame-rate gaming or intensive multitasking, the device delivers a seamless and reliable user experience. These results solidify its position as a top-tier choice for enthusiasts who refuse to compromise on power. It is clear that the iQOO 15 isn't just built for speed, but for enduring performance under pressure.
