The RAM Decision in 2026
DDR5 has been out for a few years now, and prices have finally become reasonable. But is it worth upgrading from DDR4? Let's break it down.
DDR5 vs DDR4: Key Differences
| Feature | DDR4 | DDR5 |
|---------|------|------|
| Base Speed | 2133-3200 MHz | 4800-8000+ MHz |
| Typical Gaming | 3200-3600 MHz | 5600-6400 MHz |
| Voltage | 1.2-1.35V | 1.1-1.35V |
| Capacity/DIMM | Up to 32GB | Up to 64GB |
| Latency | Tighter (CL16-18) | Looser (CL30-40) |
Real-World Performance
Gaming (1080p, CPU-bound):
- DDR5-6000: ~5-10% faster than DDR4-3600
- The gap narrows at higher resolutions
Productivity:
- Video editing: DDR5 shows bigger gains
- 3D rendering: Noticeable improvement
- Office work: You won't notice
Gaming Verdict: DDR5 is faster, but not dramatically for most games.
When DDR5 Makes Sense
Upgrade NOW if:
- Building new with Intel 12th gen+ or AMD 7000+
- You do memory-intensive productivity work
- You want the latest platform features
- DDR5 prices fit your budget
Stick with DDR4 if:
- Your current system uses DDR4
- Gaming is your main use
- Budget is tight
- DDR4 system is still fast enough
The Hidden Cost
Remember: You can't just swap RAM.
DDR5 requires:
- DDR5-compatible motherboard
- Compatible CPU (Intel 12th+ or AMD 7000+)
- Potentially new cooler (different socket)
A "RAM upgrade" becomes a platform upgrade: $400-800 minimum.
DDR5 Buying Tips
What to look for:
1. Speed: DDR5-6000 is the sweet spot for AMD
2. Latency: CL30-36 is good, CL40+ is loose
3. Capacity: 32GB is ideal, 16GB is minimum
4. Brand: Crucial, G.Skill, Corsair, Kingston are reliable
5. XMP/EXPO: Ensure your motherboard supports the profile
Our Recommendation for 2026
New builds: Go DDR5. It's the future, prices are good, and platforms are mature.
Existing DDR4 systems: Keep what you have unless you're CPU-limited or doing heavy productivity work. Put upgrade money toward GPU instead.
