LPDDR5/LPDDR5X is Better than you think:
LPDDR5 /LPDDR5X replacing DDR5 in laptops is a rising trend driven by the need for better power efficiency and compact designs. LPDDR5 is becoming the preferred choice for premium Slim laptops.
Things to Know Before You Buy a Laptop with LPDDR5
- - DDR5 is faster than LPDDR5/LPDDR5X, but the difference is unnoticeable in low to mid-range laptops.
- - LPDDR5/LPDDR5X is soldered to the laptop motherboard and cannot be upgraded.
- - LPDDR5/LPDDR5X is more expensive than DDR5.
- - LPDDR5X consumes less power and very low power at idle.
- - It is worth noting that high-performance laptops like Asus A14 (Ryzen 7 8845HS, RTX 4050) have 16GB LPDDR5X in dual channel.
- - DDR5 is easier to repair and replace.
LPDDR5 VS DDR5 :
Feature |
DDR5 |
LPDDR5 |
Power Consumption |
Higher (1.1V–1.2V) |
Lower (1.05V or less) |
Speed |
Up to 8400 MT/s |
Up to 6400 MT/s (8533 MT/s for LPDDR5X) |
Form Factor |
Larger DIMMs (user-replaceable) |
Soldered to the motherboard (non-upgradable) |
Battery Life Impact |
Shorter battery life |
Longer battery life due to power efficiency |
Thermal Efficiency |
Generates more heat |
Lower heat generation, better thermal management |
Target Use Case |
Desktops, gaming laptops, workstations |
Ultraportables, premium laptops, high-performance laptops |
Upgradability |
User-upgradable |
Non-upgradable |
Cost |
Typically more expensive for higher-end specs |
Typically more cost-effective for premium ultrabooks |
Performance |
Best suited for heavy task |
Adequate for performance, balanced with battery life |
Slim Laptops:
Most of slim laptops like like Asus Zenbook S 14( Intel Core Ultra 7 258V),HP ENVY (Intel Core Ultra 5 ) uses LPPDR ram to reduce space and reduce the ideal battery consumption
LPDDR5 iGPU Perormance:
the integrated GPU tend to perform bit faster in LPDDR5 but performance is not directly from the LPDDR-ram but from but the way it implemented in motherboard by the manufacturer(can differ from manufacturer to manufacturer)
Conclusion:
LPDDR5 performs similarly to DDR5 in day-to-day tasks while being more energy-efficient. However, remember that LPDDR cannot be upgraded, so it’s recommended to purchase at least 16GB.
