Qualcomm Snapdragon 8 Gen 2: First benchmarks point out a leap in efficiency
With a revised graphics unit and sooner and newly sorted CPU cores, the Snapdragon 8 Gen 2 is Qualcomm’s quickest system-on-chip (SoC) up to now. The primary checks that heise on-line was capable of perform in the midst of the Snapdragon Summit 2022 affirm the leaps in efficiency talked about by Qualcomm. Nonetheless, the brand new processor doesn’t solely lag behind its direct predecessor. The benefit over Apple can also be rising in sure disciplines.
A Qualcomm Reference Design (QRD) was out there for the benchmarks. This can be a smartphone with the Snapdragon 8 Gen 2 specifically developed for checks. With a show decision of 2400 × 1080 pixels, 12 GB of LPDDR5X RAM and Android 13, the QRD doesn’t have any uncommon gear. Nonetheless, as a consequence of attainable unknown optimizations, the measured values can not essentially be transferred 1:1 to future sequence smartphones.
Qualcomm speaks of as much as 35 p.c increased CPU efficiency in comparison with the Snapdragon 8 Gen 1. Nonetheless, it’s unclear which particular person measures are answerable for this improve. As a result of the corporate has not revealed many technical particulars. Amongst different issues, it’s unclear how giant the caches are and what adjustments there are to the CPU cores in comparison with ARM’s commonplace designs.
A reference smartphone from Qualcomm was used for the primary checks. The efficiency of the later sequence smartphones ought to deviate accordingly.
Qualcomm solely named the CPU fashions and the utmost clock charges. The prime core (ARM Cortex-X3) reaches 3.19 GHz, the 4 efficiency cores (two every ARM Cortex-A710 and -A715) 2.8 GHz and the three effectivity cores (ARM Cortex-A510 Refresh) calculate with a most of two GHz. However not solely the utmost clock charge, which is increased in every efficiency degree, and using new cores ought to affect the general efficiency. The extra efficiency core – there have been solely three within the Snapdragon 8 Gen 1 – also needs to give an extra increase.
Within the Geekbench CPU benchmark, the single-core efficiency of the Snapdragon 8 Gen 2 is sort of 21 p.c increased than that of the primary technology. In comparison with their accelerated new version Snapdragon 8+ Gen 1, the plus remains to be virtually 14 p.c. The lead in multi-core efficiency is even better. In comparison with the Snapdragon 8 Gen 1, the brand new mannequin calculates 42 p.c sooner, in comparison with the Snapdragon 8+ Gen 1 it’s nonetheless 25 p.c sooner.
The Qualcomm Snapdragon 8 Gen 2 clearly surpasses its predecessors by way of CPU efficiency, however Apple is once more forward.
In comparison with Apple, nevertheless, Qualcomm’s new cellular processor is once more defeated. The Bionic A16 with its whole of six CPU cores, which is discovered within the iPhone 14 Professional (take a look at), amongst different issues, provides 26 p.c increased single and 5 p.c increased multi-core efficiency. And even the Bionic A15 solely surpasses the Snapdragon 8 Gen 2 when utilizing all cores.
Mockingly, a very powerful change with regard to the graphics unit can’t be estimated. As a result of benchmark applications that may consider the ray tracing efficiency weren’t out there on the time of the take a look at. The efficiency losses related to the extra reasonable calculation of sunshine rays should due to this fact be proven by later measurements with sequence smartphones.
Other than that, Qualcomm speaks of a 25 p.c increased graphics efficiency, and even 30 p.c when utilizing the low-level Vulkan graphics API. How these will increase come about is unclear. As a result of Qualcomm doesn’t give any technical knowledge for the Adreno graphics unit.
The graphics unit of the Snapdragon 8 Gen 2 is the quickest out there in smartphones as of the tip of 2022.
Within the graphics benchmark GFXBench, the efficiency of the Snapdragon 8 Gen 2 is round 40 p.c increased than its predecessor in all three take a look at situations. The Snapdragon 8+ Gen 1 can also be slower: the brand new chip trumps it by about 25 p.c. Not like by way of CPU efficiency, Qualcomm is clearly forward of Apple on this space. The lead over the GPU of the Bionic A16 is 27 to 48 p.c, relying on the situation. Nonetheless, it must be famous that the efficiency specs of the three GFXBench checks seek advice from the show in 1920 × 1080 pixels. Precise efficiency at native decision might differ.
The 3DMark suite was out there for measuring the system efficiency. Along with the CPU and GPU, the principle reminiscence additionally performs a task right here. In comparison with its predecessor, the Snapdragon 8 Gen 2 achieved a 50 p.c increased score within the Wildlife Excessive take a look at. In comparison with the Snapdragon 8+ Gen 1, the plus remains to be 35 p.c. As within the earlier 12 months, Apple finally ends up simply behind Qualcomm.
In 3DMark, the Qualcomm Snapdragon 8 Gen 2 takes first place, not least due to its graphics unit. Smartphones geared up with the chip ought to supply greater than sufficient efficiency for video games.
The good points are even clearer when in comparison with the two-year-old Snapdragon 888. In comparison with that, the brand new processor achieves greater than 150 p.c higher efficiency.
At the least within the tailored take a look at smartphone, the Snapdragon 8 Gen 2 provides a considerably increased CPU and graphics efficiency than its predecessor and its accelerated variant. It stays to be seen what is going to occur to the consumer. Final however not least, the Snapdragon 8 Gen 1 has proven that there’s a big selection of efficiency relying on the smartphone. Ultimately, it isn’t solely the particular gear within the type of working reminiscence and show decision that’s decisive, but additionally the difference of the software program. Temperature administration, i.e. cooling, can also be necessary. Within the first checks, the efficiency typically dropped by about 5 p.c below extended full load.
In comparison with Apple’s SoC Bionic A16, Qualcomm advantages from a stronger graphics unit. By way of CPU efficiency, nevertheless, the Snapdragon can not sustain once more. Right here, Apple as soon as once more advantages from its personal core design. As a substitute, Qualcomm is basically restricted to what ARM specifies.
With the MediaTek Dimensity 9200 there’s additionally an enormous unknown. The processor introduced at the start of November 2022 makes use of a special CPU construction and a special graphics unit in comparison with the Snapdragon 8 Gen 2. In line with MediaTek, nevertheless, it ought to outperform its predecessor by round 10 and 30 p.c (CPU, GPU). That may land it within the Snapdragon 8 Gen 2 vary. (pbe)
