The Snapdragon 8 Gen 3 has so far impressed with its suite of features focused on increased CPU and GPU performance, along with support for hardware-accelerated ray tracing, AI, and more. However, for Qualcomm’s latest SoC to have any considerable gains against the Snapdragon 8 Gen 2 for Galaxy, the company had to increase its maximum power consumption, which, in turn, negatively affected its efficiency. Let us check out the latest details and see the performance results.
Efficiency score of the Snapdragon 8 Gen 3 suffers 11 percent against the Snapdragon 8 Gen 2 as a result of the increased power consumption
Like the Snapdragon 8 Gen 2 for Galaxy, the Snapdragon 8 Gen 3 features a single high-performance core, but this year, Qualcomm has gone in a different direction, increasing the clock speed of all the Cortex-A720 cores, which will help increase the SoC’s multi-core performance. Unfortunately, X user Golden Reviewer ran the SPECint06 Big Core benchmark on the Xiaomi 14 Pro, which is powered by the Snapdragon 8 Gen 3, and found that while the latter obtains a 13 percent higher score of 69.28 compared to the overclocked Snapdragon 8 Gen 2’s 60.86 score, it is at the expense of power consumption, which reached 6.27 watts.
That figure is 28 percent higher than what the Snapdragon 8 Gen 2 for Galaxy consumed, peaking at 4.90 watts, with a higher performance-per-watt score than the Snapdragon 8 Gen 3. The regular version of the Snapdragon 8 Gen 2 exhibits even better power efficiency than the Snapdragon 8 Gen 3, hinting that Qualcomm may have hit a limit by sticking with TSMC’s 4nm ‘N4P’ process this year and had to compensate for the performance difference by raising the power consumption. These changes will obviously lead to higher temperatures, rapid battery life reduction, and other disadvantages.
Tested CPU in #Snapdragon8Gen3 #Xiaomi14Pro
Now I’m concerned.
Performance is great, the best we’ve seen so far from any Android SOC, it’s 13% faster than Snapdragon 8 Gen 2 For Galaxy.
However power consumption has gone up 28%, and efficienty down 11%.

Golden Reviewer also states that phone makers that intend to use the Snapdragon 8 Gen 3 will have to tune the 8-core CPU cluster intelligently and avoid letting the performance cores reach their highest clock speed, otherwise, it can result in severe performance degradation. The Xiaomi 14 Pro features a vapor chamber, so it might be able to tame the flagship chipset’s thermals, but any less than this, and the handset might thermal throttle almost immediately.
