Snapdragon SoC guide: All of Qualcomm's smartphone processors explained (2024)

Qualcomm

Qualcomm’s Snapdragon processors are among the most ubiquitous SoCs in the Android smartphone space. Samsung uses Snapdragon for its Galaxy S line in various markets, but these chips also power the vast majority of flagship Android phones on the market. There’s a good chance that you’re reading this on a device using a Qualcomm Snapdragon processor right now.

Snapdragon chips aren’t just found in expensive flagship smartphones though. There’s a whole portfolio of processors built for handsets at various price points. Performance and features differ a fair bit between these models, so let’s break down how the company’s latest SoCs compare and what capabilities you should expect.

Snapdragon 8 series — Premium tier

Looking for the very best Qualcomm smartphone processor family? That will be the Snapdragon 8 range. The latest chip is the Snapdragon 8 Gen 3, which was announced in October 2023. It’s a brand-new release that’s only appeared in the Xiaomi 14 series as of writing. But it’s expected to power a ton of flagship phones in 2024.

The Snapdragon 8 Gen 3 brings a host of upgrades. For one, it packs a super-powerful CPU on paper. This is a 1+5+2 CPU consisting of one Cortex-X4 core, five Cortex-A720 cores, and two Cortex-A520 cores. In fact, Qualcomm says it’s 30% faster than its predecessor while being 20% more efficient.

The Snapdragon 8 Gen 3 is built with on-device generative AI tasks in mind.

Qualcomm is also going all-in on generative AI capabilities this time out, offering text-to-image generation in under a second, photo expansion capabilities (using image generation to expand the borders of an image), and support for large language models with over 10 billion parameters running at close to 15 tokens per second. In plain English, this is an AI powerhouse.

Other upgrades worth knowing include an Adreno GPU that’s 25% faster and 25% more efficient, support for global illumination graphics tech, night mode video support, and video object eraser capabilities.

The Snapdragon 8 Gen 3’s predecessor is the Snapdragon 8 Gen 2, and most of 2023’s flagship Android phones are powered by this chip. It’s still a beast, bringing a powerful 1+4+3 CPU, a top-class GPU, and upgrades in plenty of other areas.

We also still see phones with 2022’s Snapdragon 8 Gen 1 and 8 Plus Gen 1 chips. In fact, the latter chip is used inside quite a few upper mid-range phones.

Snapdragon 7 series — Bridging the gap

Qualcomm’s Snapdragon 7 series isn’t quite as straightforward as its flagship 8 series. This is due to the sheer number of them, as well as the older, lower-end chips crossing into Snapdragon 6 territory. The Snapdragon 7 series was originally conceived as an upper mid-range family of processors, but the Snapdragon 7 Plus Gen 2 blurs the line between flagship and mid-range like no other chip before it.

This chipset was announced in early 2023 and looks more like a Snapdragon 8 Plus Gen 1 processor than anything else. You’ve got the same TSMC 4nm design, a very similar CPU (one Cortex-X2, three Cortex-A710, four Cortex-A510), and what seems like a similarly powerful ISP. We do see some compromises though, such as a less impressive but still powerful GPU, the mid-tier Snapdragon X62 modem, and missing features like 8K recording.

The Snapdragon 7 Plus Gen 2 is basically 2022's flagship silicon with a few changes and a GPU downgrade.

We put a Snapdragon 7 Plus Gen 2 reference device through some benchmarks too, finding that the chipset was just as powerful as the Snapdragon 8 Gen 1 when it came to CPU performance. There was still a sizeable performance gap when it came to GPU-related tests, but it delivered rock-solid sustained performance. Most of these findings were reflected in our time with the POCO F5, the first commercial phone with this chip.

2022’s Snapdragon 7 Gen 1 preceded the Snapdragon 7 Plus Gen 2, and it was pretty impressive. Expect an octa-core CPU setup here, featuring four powerful Cortex-A710 cores and four Cortex-A510 cores. Qualcomm says the new chipset also delivered a 20% boost in GPU power over the Snapdragon 778G and a 30% improvement in machine learning performance. Other notable features include 200MP camera support, 4K HDR recording, and a 4nm design. Unfortunately, few phones with this chipset actually saw the light of day.

Qualcomm also announced the Snapdragon 7s Gen 2 in September 2023. Don’t let the name fool you as this isn’t a sequel to the Snapdragon 7 Gen 1. Instead, this chip is a step below the 7 Gen 1. You’ve still got a great CPU (four Cortex-A78 and four Cortex-A55) and a 4nm design, but this chip lags behind as far as connectivity and camera capabilities are concerned.

2o21’s Snapdragon 780G is another notable chipset in this tier, bringing a 5nm design and a respectable triple-tiered CPU. You’re looking at one Cortex-A78 CPU clocked at 2.4GHz, three Cortex-A78 CPUs clocked at 2.2GHz, and four Cortex-A55 CPU cores. The Snapdragon 780G also delivered an Adreno 642 GPU that’s said to offer performance in line with older flagships. That was pretty significant at the time as Qualcomm’s mid-range chips previously lagged far behind older flagship processors.

Snapdragon 6 series — Value for money

Where the Snapdragon 7 series tries to bridge the gap between mid-range and flagship, the Snapdragon 6 series is mostly focused on the ~$300 and under segment. And the most notable processor in this family is the Snapdragon 6 Gen 1.

The Snapdragon 6 Gen 1 is a significant step up from previous Snapdragon 6 series SoCs, offering a powerful CPU (4x Cortex-A78, 4x Cortex-A55) and an improved Adreno GPU. In fact, Qualcomm claims a 40% and 35% performance boost over the Snapdragon 695’s CPU and GPU respectively. Other notable features include a 4nm design, 200MP snapshot support, and 4K video capture.

The previous top-end processor in this series was the Snapdragon 695, being an incremental upgrade over 2020’s Snapdragon 690. The 695 brings a capable octa-core CPU (2x Cortex-A77 and 6x Cortex-A55), and an Adreno 619 GPU seen in the Snapdragon 750G. We also get 13MP triple camera support, 108MP single camera support, and Wi-Fi 6 connectivity. But the big disappointment here is that it lacks 4K video recording.

Qualcomm also launched the Snapdragon 680 at the same time as the 695, and this chip stands out from the above entries by being a 4G-only SoC. It seems to be derived from the older, budget Snapdragon 665 SoC, sharing features like old CPU cores (four Cortex-A73 and four Cortex-A53), the Adreno 610 GPU, Hexagon 686 DSP, and Quick Charge 3.0 fast charging. There are a couple of upgrades though, namely a much smaller 6nm manufacturing process and Bluetooth 5.1 support.

Snapdragon 4 series — Entry-level

Now we come to the least capable Snapdragon series (aside from the shuttered/dormant Snapdragon 200 family), designed for cheap phones. But there’s good news here, as the latest Snapdragon 4 chipset is actually a massive improvement.

The Snapdragon 4 Gen 1 offers a 6nm design, a pretty capable CPU (2x Cortex-A78, 6x Cortex-A55), and a 10% faster GPU than the earlier Snapdragon 480. Otherwise, this SoC has quite a few things in common with the Snapdragon 695. We’ve got the same X51 5G modem, similar camera capabilities (no 4K recording here), 120Hz support at FHD+ display resolution, and Wi-Fi 5.

The Snapdragon 4 series lacks features like a powerful GPU and 4K recording but gains high refresh rate support and 5G.

Go down a notch and we’ve got the Snapdragon 480. This was the first 5G-enabled processor in the Snapdragon 4 series, being announced in early 2021. This is essentially a cut-back Snapdragon 750G chipset, featuring mmWave 5G support, the same Adreno 619 GPU, the same 8nm manufacturing process, Quick Charge 4 Plus tech, and support for FHD+ 120Hz displays.

We do see a few compromises though, such as older CPU cores (2x Cortex-A76 and 6x Cortex-A55), less impressive camera capabilities (no 4K recording, 64MP snapshot support), and slower 5G speeds. Still, this was a major upgrade for the 4 series at the time, which lacked more modern CPUs and 5G capabilities.

The Snapdragon 480 was succeeded by the Snapdragon 480 Plus in late 2021, but this is a mild upgrade at best rather than a major step up.
