Intel Core i7-6820HQ

Intel Core i7-6820HQ in 2025: Is it worth getting this "veteran" of Skylake?
Let's explore who might benefit from this 4-core processor from 2015 in the age of neural networks and 5 nm chips.
1. Architecture and Process Technology: What Skylake Hides
The Intel Core i7-6820HQ, released in 2015, belongs to the Skylake generation — the sixth series of Intel Core. Despite its age, in 2025 it is still found in budget work laptops and refurbished devices.
- Cores and Threads: 4 physical cores and 8 threads thanks to Hyper-Threading. Base frequency is 2.7 GHz, turbo mode boosts it to 3.6 GHz (one core) or 3.2 GHz (all cores).
- 14 nm Process Technology: A breakthrough for its time, but today even budget chips are manufactured using 7–10 nm processes (e.g., Intel Alder Lake or AMD Zen 3).
- Integrated Graphics HD Graphics 530: 24 EU (Execution Units), base frequency of 350 MHz, turbo up to 1050 MHz. Supports 4K@60 Hz via DisplayPort and hardware decoding of H.265. In gaming, it provides only a "basic" level: CS:GO at low settings gives 40–50 FPS at 1080p.
Architecture Features:
- Support for DDR4-2133 MHz and LPDDR3 — relevant for upgrading older laptops.
- Improved IPC (instructions per clock cycle) by 5–10% compared to the previous Broadwell generation.
- Extended AVX2 instructions for accelerating computations in scientific tasks.
2. Power Consumption and TDP: Balancing Power and Heat
With a TDP of 45 W, the i7-6820HQ is positioned as a processor for "thick" laptops and mobile workstations.
- Heat Output: Without an efficient cooling system (such as large heat sinks and dual fans), the chip quickly reaches 90–95°C under load.
- Real Scenarios: In office tasks (Chrome, Word), power consumption drops to 10–15 W thanks to SpeedShift technology, but during rendering or gaming, it remains consistently at 45 W.
Tip: When purchasing a laptop with this CPU, check reviews regarding fan noise. For instance, the Dell Precision 5510 with i7-6820HQ is known for adequate cooling, whereas some thin models from Gigabyte may throttle.
3. Performance: What Can It Do in 2025?
Office and Multimedia:
- Chrome with 20 Tabs + Zoom: Core load is 30–40%, no lag.
- 4K Video in VLC: Integrated graphics handle it easily.
Rendering and Heavy Tasks:
- Blender (BMW demo scene): Renders in 12 minutes. For comparison, a Ryzen 5 5600H (6 cores) will complete this in 7–8 minutes.
- Photoshop (filters + layers): Delays possible when working with files larger than 2 GB.
Gaming:
- With a discrete GPU (e.g., NVIDIA GTX 1060): Pairing with the i7-6820HQ still allows for playing Apex Legends at medium settings (60 FPS at 1080p).
- Using Integrated Graphics: Only old titles like Dota 2 or Minecraft.
Turbo Boost Mode: Automatic overclocking to 3.6 GHz works reliably for short tasks (launching applications), but during prolonged workloads (streaming), the frequency drops to 3.2 GHz due to overheating.
4. Use Cases: Who Is It Suitable For?
- Students and Office Workers: For Word, Excel, Zoom, and light editing in Premiere Pro (1080p).
- Engineers: Compatible with AutoCAD 2025 (requires at least 4 cores), but complex 3D models may lag.
- Budget Gamers: Only when paired with a discrete GPU, like the GTX 1650.
Not Suitable For:
- Vloggers working with 4K videos in DaVinci Resolve.
- AI enthusiasts (Stable Diffusion, local LLMs) — lacking cores and AVX-512 support.
5. Battery Life: How Long Will It Last?
- Laptops with i7-6820HQ typically come equipped with batteries ranging from 50–60 Wh. By 2025, such batteries may already be degraded, but in new models (if any exist), the operating time will be:
- 6–7 hours for web surfing (brightness at 50%, Wi-Fi on).
- 1.5–2 hours under load.
- Power-Saving Technologies:
- SpeedStep: Dynamic frequency drop during idle.
- C-states: Disabling unused cores.
Recommendation: Choose laptops with a battery of at least 70 Wh and support for fast charging (e.g., HP ZBook 15 G3).
6. Comparison with Competitors: How Does It Stand Out?
- Intel Core i5-1135G7 (2020): 4 cores/8 threads, 10 nm, Iris Xe. In Geekbench 6 Multi-Core — 4200. Consumes half the power (28 W) but starts at $600 in new ultrabooks.
- AMD Ryzen 5 5500U (2021): 6 cores/12 threads, 7 nm, Vega 7. Multi-threaded performance — 4800 points. Laptops with it start at $550.
- Apple M1 (2020): 8 cores, 5 nm. Geekbench 6 Multi-Core — 7500. Priced from $900 — a clear favorite, but only for macOS.
Conclusion: In 2025, the i7-6820HQ is a choice for those looking for an affordable Windows laptop for basic tasks (up to $400–500 for a new device).
7. Pros and Cons
Strengths:
- Affordable laptop prices (new models — $450–600).
- Support for up to 64 GB DDR4 — useful for virtualization.
- Reliability: A proven architecture over the years.
Weaknesses:
- No support for PCIe 4.0, Thunderbolt 4.
- High heat output.
- Outdated iGPU: Will struggle with modern AV1 codecs.
8. Laptop Selection Recommendations
- Type of Device:
- Workstation: Dell Precision 3510 (4 RAM slots, ECC support).
- Budget Gaming Laptop: MSI GE62 Apache Pro (with GTX 1060, often found in new stock for $700).
- What to Look For:
- SSD size (at least 512 GB NVMe).
- Ports: USB-C with Power Delivery for charging.
- Display: IPS with Anti-Glare coating.
9. Final Conclusion: Who Is the i7-6820HQ Suitable For in 2025?
This processor is suitable for:
- Budget Users looking for a Windows laptop for study and work without frills.
- Upgrade Enthusiasts: Buying a used model for $200–300 and adding RAM and an SSD can extend its life by 2–3 years.
- Corporate Clients: Where stability matters more than innovation.
Key Benefits: Low cost, proven reliability, adequate power for everyday tasks. However, if your budget allows for an additional $100–200, consider opting for a Ryzen 5 or Core i5 of the 11th generation: they will offer greater performance with less heat.
