Snapdragon 8 Gen 3 Sees Double-Digit Efficiency Positive factors In opposition to Overclocked Snapdragon 8 Gen 2, However At A 28 P.c Energy Consumption Enhance

The Snapdragon 8 Gen 3 has to this point impressed with its suite of options targeted on elevated CPU and GPU efficiency, together with assist for hardware-accelerated ray tracing, AI, and extra. Nevertheless, for Qualcomm’s newest SoC to have any appreciable good points in opposition to the Snapdragon 8 Gen 2 for Galaxy, the corporate needed to enhance its most energy consumption, which, in flip, negatively affected its effectivity. Allow us to try the newest particulars and see the efficiency outcomes.
Effectivity rating of the Snapdragon 8 Gen 3 suffers 11 p.c in opposition to the Snapdragon 8 Gen 2 on account of the elevated energy consumption
Just like the Snapdragon 8 Gen 2 for Galaxy, the Snapdragon 8 Gen 3 contains a single high-performance core, however this yr, Qualcomm has gone in a special course, rising the clock pace of all of the Cortex-A720 cores, which can assist enhance the SoC’s multi-core efficiency. Sadly, X person Golden Reviewer ran the SPECint06 Huge Core benchmark on the Xiaomi 14 Professional, which is powered by the Snapdragon 8 Gen 3, and located that whereas the latter obtains a 13 p.c larger rating of 69.28 in comparison with the overclocked Snapdragon 8 Gen 2’s 60.86 rating, it’s on the expense of energy consumption, which reached 6.27 watts.
That determine is 28 p.c larger than what the Snapdragon 8 Gen 2 for Galaxy consumed, peaking at 4.90 watts, with the next performance-per-watt rating than the Snapdragon 8 Gen 3. The common model of the Snapdragon 8 Gen 2 displays even higher energy effectivity than the Snapdragon 8 Gen 3, hinting that Qualcomm might have hit a restrict by sticking with TSMC’s 4nm ‘N4P’ course of this yr and needed to compensate for the efficiency distinction by elevating the ability consumption. These modifications will clearly result in larger temperatures, fast battery life discount, and different disadvantages.
Examined CPU in #Snapdragon8Gen3 #Xiaomi14Pro
Now I am involved.
Efficiency is nice, the most effective we have seen so removed from any Android SOC, it is 13% quicker than Snapdragon 8 Gen 2 For Galaxy.
Nevertheless energy consumption has gone up 28%, and efficienty down 11%.
Now that is fairly scary pic.twitter.com/6LBKL7k9W2— Golden Reviewer (@Golden_Reviewer) November 19, 2023

Golden Reviewer additionally states that cellphone makers that intend to make use of the Snapdragon 8 Gen 3 must tune the 8-core CPU cluster intelligently and keep away from letting the efficiency cores attain their highest clock pace, in any other case, it can lead to extreme efficiency degradation. The Xiaomi 14 Professional contains a vapor chamber, so it would be capable of tame the flagship chipset’s thermals, however any lower than this, and the handset may thermal throttle virtually instantly.
