Snapdragon 8 Gen 3 vs Snapdragon 8 Gen 2: What's new and should you upgrade?

Qualcomm has released its Snapdragon 8 Gen 3 chip that’s set to power many of the flagship Android phones released through the end of 2024 and even most of 2025. A wide range of brands, ranging from Samsung to Xiaomi, have released devices powered by this chipset. But what upgrades does the Snapdragon 8 Gen 3 bring to the table, and how does it compare to Qualcomm’s former best, the Snapdragon 8 Gen 2? Let’s break it down.

Snapdragon 8 Gen 3 vs Snapdragon 8 Gen 2: Specs

With its latest Snapdragon 8 Gen 3 chip, Qualcomm promises a big performance and efficiency improvement. Here’s a spec table that showcases what the company has changed between the two chip generations.

Qualcomm has made some interesting changes to its formula compared to last year, with the Snapdragon 8 Gen 3 adding an extra medium core and dropping a little core. Even though the total core count remains the same at eight, we’re getting a different 1+5+2 core layout that places more emphasis on the middle tier. The cores themselves are different too. The Snapdragon 8 Gen 3 includes Arm’s latest Cortex-X4 big core, Cortex-A720 medium cores, and Cortex-A520 cores.

Qualcomm has also clocked each core higher than last year, with the Snapdragon 8 Gen 3’s big core topping 3.3GHz and three of the medium cores achieving 3.2GHz. For comparison, last year’s Snapdragon 8 Gen 2’s big core came close at 3.2GHz. However, all four medium cores were capped at 2.8GHz.

While we can’t directly compare clock speeds between cores from different generations, it’s a good sign for performance as we’ll discuss in the section on real-world benchmarks below. And despite the clock speed increase, Qualcomm says it hasn’t compromised on power draw. The new CPU is 20% more efficient than its predecessor.

It’s worth noting that Qualcomm’s inclusion of the latest Arm cores means that the Snapdragon 8 Gen 3 is a 64-bit-only chipset. Put simply, some older Android apps that haven’t been updated in nearly a decade will no longer run on the newer SoC. If that matters to you, the last-gen Snapdragon 8 Gen 2 will go down as the last flagship chipset to support 32-bit apps.

As is typically the case, the Snapdragon 8 Gen 3 packs a new Adreno GPU. Qualcomm pegs it at 25% faster vs the Snapdragon 8 Gen 2’s Adreno 740 and promises an equal 25% improvement in efficiency. Ray tracing gets a monstrous 50% performance uplift this generation, but we haven’t seen many compelling applications of the technology on mobile yet.

The new Adreno GPU also has a few other tricks up its sleeve, namely 8K display-out and 240Hz support. Even so, Qualcomm states that this GPU generation represents an evolutionary upgrade rather than an outright overhaul.

Snapdragon 8 Gen 3 vs Snapdragon 8 Gen 2: Benchmarks

With the theory out of the way, how does the Snapdragon 8 Gen 3 fare in actual tests? We’re now in a position to answer that question, thanks to Qualcomm’s reference device that showcases the chip at its best. We’ve compiled our testing in a dedicated Snapdragon 8 Gen 3 benchmark article, but here’s a quick look at how it compares to its predecessor.

In GeekBench 6, Qualcomm’s latest chip puts up an impressive showing and lives up to the company’s claimed performance figures. The Snapdragon 8 Gen 3 offers a 40% uplift in multi-core and 18% improvement in single-core vs last year’s Snapdragon 8 Gen 2 in 2023 phones.

The gap is slightly smaller when compared to Qualcomm’s device from last year, which is expected as retail devices don’t always match the reference. Still, it’s an impressive result, with the Snapdragon 8 Gen 3 achieving 31% higher peak performance year-over-year. The new Cortex-X4 and Cortex-A720 cores seem to live up to their promise.

The winning streak continues on the GPU side. Our 3DMark Wild Life scores give the Snapdragon 8 Gen 3 a 40% lead over last year’s chip, which is above and beyond the claimed 25%. Qualcomm has reportedly alleviated some Vulkan-specific bottlenecks, which should help explain the increased performance in select titles. Likewise, ray tracing can become a target for developers now that the Snapdragon 8 Gen 3 offers 50% better performance.

However, it’s not all good news. The Snapdragon 8 Gen 3 starts out strong but nosedives to half of its peak performance within a few runs of the 3DMark Wildlife Stress Test. Smartphones equipped with last year’s Snapdragon 8 Gen 2 didn’t fall off quite as hard. The latter SoC’s performance simply declined gradually over time. We noticed the same results while benchmarking the Galaxy S24, the chip’s peak performance does indeed take a noticeable hit in sustained loads.

Snapdragon 8 Gen 3 vs Snapdragon 8 Gen 2: AI and other features

Last year, the Snapdragon 8 Gen 2 introduced some long-awaited features like support for the AV1 video codec, LPDDR5X RAM, UFS 4.0, and Wi-Fi 7. All of these carry over to the Snapdragon 8 Gen 3 too, along with some more improvements. AI has also taken center stage in the tech world and Qualcomm is embracing that trend wholesale with its new flagship SoC. Here’s a quick rundown of the new features coming to the Snapdragon 8 Gen 3:

• According to Qualcomm, the Snapdragon 8 Gen 3’s Hexagon NPU offers nearly double the performance vs the Snapdragon 8 Gen 2. It’s also 40% more efficient and has been designed with generative AI in mind.
• The Snapdragon 8 Gen 3 can run large language models (LLMs) on-device. The company showcased a chatbot demo powered by Meta’s Llama 2 language model, which is an open-source competitor to ChatGPT.
• Beyond text, the Snapdragon 8 Gen 3 also supports multi-modal models that can locally handle text, image, and even speech. For example, the chip can create an AI-generated image using Stable Diffusion within a minute. It can also erase objects in videos, a step beyond Google’s Magic Eraser which only works for still photos.
• Qualcomm’s AI focus extends to the chip’s image processing pipeline too, with the chip’s Night Vision Video capable of shooting usable footage in very dark settings.
• Likewise, a new Photo Expansion feature uses generative AI to extend any image beyond its original boundaries. This is a feature we’ve seen already from the likes of Photoshop Generative Fill, but it’s new on mobile.
• The Snapdragon 8 Gen 3 introduces support for Dolby HDR photo capture with 10-bit color depth.

While these features sound very promising, it’s worth noting that their implementation is entirely up to device makers. Based on past releases, we know that only a small subset of Snapdragon 8 series’ features end up in actual consumer devices every year. Samsung unveiled its Galaxy AI software suite alongside the S24 family, but many of the features are also available on older devices so it’s a bit unclear how much of a role the Snapdragon 8 Gen 3’s upgraded Neural Processing Unit (NPU) plays.

Snapdragon 8 Gen 3 vs Snapdragon 8 Gen 2: Phones and bottom line

The Snapdragon 8 Gen 2 powers many of the best Android smartphones released in 2023. We’ve almost universally praised it on account of its superb performance and efficiency. The Snapdragon 8 Gen 3 looks like a worthy successor in just about every area. Having said that, we have some lingering questions about sustained performance, given our early test results. After all, this is an area where Android SoCs have struggled in the past.

Qualcomm released the Snapdragon 8 Gen 3 on October 24, 2023. It didn’t take long for the first phone sporting the chipset to hit the market in the form of the Xiaomi 14 series, followed by the Galaxy S24 series, OnePlus 12, and Zenfone 11 Ultra. Later in 2024, the SoC also powered other noteworthy devices like the Asus ROG Phone 8, Galaxy Z Flip 6, and Galaxy Z Fold 6.

Simultaneously, however, we don’t expect the Snapdragon 8 Gen 2 to disappear just yet. Qualcomm’s previous-gen SoCs have often made a comeback later in their life cycles in upper mid-range and sub-flagship smartphones. The same should hold true for this last-gen chip too. And considering the amount of performance on offer, it’s undoubtedly a great choice even if it’s no longer the best. The OnePlus 12R is a perfect example as it packs the Snapdragon 8 Gen 2 at just $499.

Having said that, Qualcomm also surprised us by releasing the Snapdragon 8s Gen 3, which is a cut-down version of the flagship chip we’ve discussed so far. Primarily destined for the affordable sub-flagship market, the chip delivers many of the architectural benefits of the latest Arm cores while sacrificing clock speeds. In simpler terms, the chip is a good stop-gap between the Snapdragon 8 Gen 2 and 8 Gen 3, both in terms of performance and cost.

So with that in mind, which SoC should you prioritize for your next smartphone? Given the huge performance uplift, we’d say the Snapdragon 8 Gen 3 does eke out a win vs the Snapdragon 8 Gen 2. However, that equation may change slightly if you can find deep discounts on a smartphone toting the older SoC.
