3. Virtualization Technology (VT-x/d): Light VM support

4. Enhanced Intel SpeedStep: Power efficiency

Compatibility & Cooling

• Socket LGA 1200 (300-series motherboards)

• Requires BIOS update for compatibility

• Includes basic thermal solution (no aftermarket cooler needed)

Ideal Use Cases

✅ Home/office PCs
✅ Budget builds
✅ Media centers
✅ School/education systems

Limitations

❌ Only 2 cores (not for heavy workloads)
❌ PCIe 3.0 (slower than PCIe 4.0/5.0)
❌ Weak integrated graphics

With a 3-year warranty (excluding cooler), the G6405 offers excellent value for budget-conscious users needing reliable computing power.

1. CPU Performance

• The 4.10 GHz base clock ensures smooth performance for web browsing, office apps (Word, Excel), and light multitasking.

• Hyper-Threading (4 threads) helps with background tasks, though it’s not ideal for heavy workloads like video editing.

• Cinebench R20 Score: ~500-600 points (similar to older i3 processors).

• PassMark Rating: ~3,500 (good for basic computing but falls short in multi-core workloads).

2. Gaming Performance

• The Intel UHD 610 can handle light gaming (e.g., Minecraft, CS:GO at low settings).

• Not suitable for modern AAA games (requires a dedicated GPU).

• 4K video playback is supported via DisplayPort (60Hz).

3. Power Efficiency

• 58W TDP means it runs cool with a stock cooler.

• Ideal for small form factor (SFF) PCs and budget builds.

Advanced Features

1. Intel Smart Cache & Turbo Boost

• 4MB L3 cache improves responsiveness in everyday tasks.

• Intel Turbo Boost 2.0 dynamically adjusts clock speeds for better efficiency.

2. Memory & Storage Support

• Dual-Channel DDR4-2666 (faster than older Pentiums).

• Optane Memory support for accelerated storage performance.

3. Virtualization & Security

• Intel VT-x & VT-d for virtualization (useful for light VM usage).

• Intel Identity Protection for enhanced security.

4. Multi-Display Support

• Triple 4K display support (via HDMI, DP, and eDP).

• Great for office setups with multiple monitors.
