Samsung and SK Hynix have officially announced DDR6 memory. Consumer products aren't here yet, but the spec is finalized. Here's the complete breakdown.
The JEDEC DDR6 standard specifies:
| Spec | DDR5 | DDR6 |
|---|---|---|
| Base speed | 3200 MT/s | 6400 MT/s |
| Max speed | 8400 MT/s | 17600 MT/s |
| Voltage | 1.1V | 1.0V |
| Prefetch | 16n | 16n (revised) |
| Bank groups | 8 | 16 |
| Channels per DIMM | 2 | 2 |
The headline: DDR6 offers 2x the bandwidth of DDR5 at launch speeds.
For gaming: Mostly no impact. Games are GPU-bound, not memory bandwidth-bound at current DDR5 speeds.
For professional workstations (video editing, 3D rendering, AI inference): Significant speedup for bandwidth-limited workloads.
For servers and AI training: Huge impact — transformer models benefit enormously from memory bandwidth.
DDR6 requires new memory controllers. This means:
When does this matter? Probably late 2026 for workstations, 2027 for mainstream.
DDR6 launch (Q4 2026): ~$300+ for 32GB kit
DDR5 concurrently: ~$120-150 (prices drop as DDR6 launches)
DDR6 mainstream (2027): ~$150-200 for 32GB
DDR5 used (2027): ~$60-80
History says: don't buy first-gen. Wait for the 2nd wave.
If you're building a PC now: No. Buy DDR5. DDR6 platforms aren't out yet. If your build is 6+ months out: DDR6 systems might be available. Watch the platform releases.
