Snapdragon 875 Specs Leaked: What We Know

Yes, a new report has leaked the core specifications of Qualcomm’s upcoming Snapdragon 875 mobile processor, revealing a 5nm design, a prime Cortex-X1 core, and an integrated 5G modem. The leak, which surfaced from a usually reliable tipster, outlines a tri-cluster CPU layout and an Adreno 660 GPU, suggesting a significant performance jump over the current Snapdragon 865. While Qualcomm has not officially confirmed these details, the specifications align with industry expectations for a late-2020 flagship chipset.

Background: The Snapdragon 800 Series Lineage

Qualcomm’s Snapdragon 800 series has powered the majority of Android flagship smartphones since 2013. Each annual iteration brings improvements in CPU performance, graphics, AI processing, and modem capabilities. The Snapdragon 865, released in late 2019, was a major step forward, but it required a separate X55 modem chip for 5G connectivity. The Snapdragon 875 is expected to follow the same annual cadence, with an official announcement likely in December 2020 and the first phones arriving in early 2021.

The 875’s significance lies not just in raw speed but in architectural changes. It is rumored to be the first Snapdragon 8-series chip built on a 5nm process, a shrink from the 7nm node used for the 865. This smaller transistor size typically allows for better power efficiency and higher clock speeds, addressing a common criticism of the 865: its higher power draw under load.

The Leaked Specifications: Core Details

The leaked spec sheet, published by a well-known industry insider, lists the following key components:

• Process: 5nm (likely Samsung’s EUV process, though TSMC is also a possibility).
• CPU: Tri-cluster layout with 1x Cortex-X1 prime core (up to 2.84GHz), 3x Cortex-A78 performance cores, and 4x Cortex-A55 efficiency cores.
• GPU: Adreno 660, with a claimed 35% performance improvement over the Adreno 650 in the 865.
• Modem: Integrated Snapdragon X60 5G modem, supporting both mmWave and sub-6GHz frequencies.
• AI: 6th generation AI Engine, with a claimed 3x improvement in tensor processing speed.

These specs, if accurate, represent a substantial upgrade. The Cortex-X1 core is ARM’s new high-performance design, custom-built to compete with Apple’s A-series chips. The integrated X60 modem is a crucial shift, as it reduces the motherboard footprint and power consumption compared to the separate X55 modem in the 865.

How the Architecture Works: Tri-Cluster and Heterogeneous Computing

The Snapdragon 875’s tri-cluster CPU is a departure from the dual-cluster design used in many previous chips. Instead of just two sets of cores (high-performance and high-efficiency), the 875 uses three tiers:

• Prime Core (Cortex-X1): Handles the most demanding tasks, such as gaming, 8K video editing, and AI inference. It is designed for maximum performance, even at the cost of power.
• Performance Cores (Cortex-A78): Manage sustained heavy workloads, like multitasking or browsing complex web pages. They offer a balance of speed and efficiency.
• Efficiency Cores (Cortex-A55): Handle background tasks, notifications, and simple apps. They consume very little power, extending battery life.

The scheduler (software that decides which core runs what) is key. It must predict the workload and assign tasks to the appropriate core without causing lag. This heterogeneous computing approach is similar to ARM’s big.LITTLE architecture but with an extra tier for peak performance.

Performance Expectations: Benchmarks and Real-World Impact

Based on the leaked specs, the Snapdragon 875 is expected to deliver a significant performance leap. Early Geekbench scores, also leaked, suggest a single-core score of around 1,100 and a multi-core score of around 4,000. To put that in perspective, the Snapdragon 865 typically scores around 900 single-core and 3,300 multi-core. This would represent a ~20% improvement in single-core and ~20% in multi-core performance.

In real-world terms, this translates to:

• Gaming: Higher and more stable frame rates in demanding titles, with better thermal management.
• Photography: Faster image processing, enabling features like 8K video recording at 30fps and 200MP camera support.
• AI: Improved voice assistants, real-time translation, and more accurate object recognition in photos.
• Connectivity: Faster download and upload speeds on 5G networks, with better battery life due to the integrated modem.

However, benchmark scores don’t always translate to everyday smoothness. The Snapdragon 865 was already more than fast enough for most users; the 875’s gains will be most noticeable in heavy workloads and future-proofing.

Common Questions and Misconceptions

Is the Snapdragon 875 compatible with my current phone? No. The 875 is a new chipset with a different socket and power management requirements. It is not upgradeable; you would need to buy a new phone.

Will the 875 overheat? The 5nm process is expected to improve thermal efficiency, but sustained heavy loads (like gaming) will still generate heat. Phone manufacturers use vapor chambers and other cooling solutions to manage this, so the actual thermals depend on the phone’s design.

Does the 875 support both mmWave and sub-6GHz 5G? Yes, the integrated X60 modem supports both, as well as carrier aggregation across them. This is a significant advantage over the X55, which supported both but not simultaneously.

Is the 875 faster than Apple’s A14 Bionic? In single-core CPU benchmarks, the A14 is likely to remain ahead. However, in multi-core and GPU tests, the 875 may close the gap. The 875’s integrated 5G modem and AI capabilities are also competitive advantages.

How to Choose a Phone with the Snapdragon 875

When the first Snapdragon 875 phones arrive (likely from Samsung, Xiaomi, OnePlus, and others), here are factors to consider beyond the chipset:

• Cooling System: Look for phones with vapor chamber cooling or multiple heat pipes, especially if you game heavily.
• Battery Capacity: The 875’s efficiency gains are real, but a 4,000mAh battery is a safer bet than 3,500mAh for all-day use.
• RAM and Storage: The 875 supports LPDDR5 RAM and UFS 3.1 storage. Ensure the phone uses these for the best performance.
• Camera System: The 875’s ISP is a major upgrade, but the lens and sensor quality still matter. Don’t buy a phone solely for the chipset if the camera hardware is mediocre.
• Software Updates: A flagship chipset is only as good as the software. Choose a brand with a strong track record of timely updates.

Comparison: Snapdragon 875 vs. Snapdragon 865 vs. Exynos 2100

The Snapdragon 875 will compete directly with Samsung’s Exynos 2100 (used in some regions) and the upcoming Exynos 2200. Historically, Snapdragon variants of Samsung phones have outperformed Exynos variants in GPU and battery life. The 875’s integrated modem and Cortex-X1 core are expected to widen this gap. However, Samsung’s partnership with AMD for GPU IP in the Exynos 2200 could change the landscape in 2022.

Compared to the 865, the 875 offers:

• ~20% faster CPU
• ~35% faster GPU
• Integrated 5G modem (vs. external)
• 5nm process (vs. 7nm)
• Support for 200MP cameras (vs. 108MP)

Frequently Asked Questions

Will the Snapdragon 875 support 4G networks?

Yes, it is fully backward compatible with 4G LTE, 3G, and 2G networks. The integrated X60 modem handles all cellular standards, so you can use the phone on any carrier, even if 5G is not available in your area.

When will the first Snapdragon 875 phones be available?

Qualcomm typically announces its flagship chipset in early December, with the first commercial devices arriving in late January or February. Samsung’s Galaxy S21 series is expected to be the first major launch, followed by Xiaomi, OnePlus, and others.

Will the Snapdragon 875 be more expensive than the 865?

Yes, it is likely to be more expensive for phone manufacturers. The 5nm process and the cost of the integrated X60 modem will increase the chipset’s price. This could lead to higher retail prices for flagship phones, unless manufacturers absorb the cost.

Is the Snapdragon 875 compatible with 5G mmWave?

Yes, the X60 modem supports both mmWave (high-band, short-range) and sub-6GHz (mid-band, longer-range) 5G. This is crucial for US carriers like Verizon and AT&T, which rely heavily on mmWave in urban areas.

Can I use a Snapdragon 875 phone with a 4G-only SIM card?

Absolutely. The phone will work with a 4G SIM, but you will only get 4G speeds. To access 5G, you need a 5G-capable SIM and a 5G plan from your carrier, though some carriers allow the same SIM to work on both.
