AMD Preps GDDR7 Radeons as Micron Kills 2GB GDDR7 Lines [2026]
Tuesday, September 22, 2026By Indie Kings | September 22, 2026
Updated September 22, 2026: AMD preps next-gen Radeon in Linux with a GDDR7 identifier plus new IH 8.0 and NBIF 7.10 blocks while Micron kills its 2GB GDDR7 catalog lines, per VideoCardz via freedesktop lists and UNIKO is Hardware. Software points at GDDR7 Radeons as Micron shifts remaining supply to 3GB parts.

AMD Linux signals
Per VideoCardz on September 22 via freedesktop plus Phoronix, engineer Frank Min added a GDDR7 entry to amdgpu_vram_names beside GDDR6, HBM3E and HBM4, reviewed by Hawking Zhang and submitted by Alex Deucher. First direct GDDR7 reference in AMD is graphics stack, per the report.
Per the report, IH 8.0 interrupt plus NBIF 7.10 bus blocks landed alongside, with DCN 6 display work already in Linux 7.3 and 7.4 trees. Enablement trains run long before launches, so read as preparation, not imminent release.
Per the report, current RX 9000 RDNA 4 cards use GDDR6 while RTX 50 uses GDDR7, so the patch points at future Radeon hardware without naming an architecture. RDNA 5 links stay leak-grade, per our draft-99 framing.
Micron 2GB exit
Per VideoCardz on September 22 via UNIKO is Hardware, the D8FHL 2GB 28Gbps chip (MT68A512M32DF-28:A) hit end of life with all Micron 2GB GDDR7 lines now EOL leaving 3GB options. Catalog pages return no results, per the evidence.
Per the report, GALAX shipped the part in an RTX 5060 with four 2GB packages for 8GB, making Micron the third RTX 50 GDDR7 supplier beside Samsung and SK hynix. The 28Gbps speed matches 5060 memory clocks, per the report.
Per the report, 3GB 24Gb parts let 4-chip boards carry 12GB and 8-chip boards 24GB, but cost more than 2GB variants today, so no full portfolio flip is expected. RTX PRO Blackwell plus 5090 Laptop already use 3GB parts, per the report.
| Memory signal per reports | Detail |
|---|---|
| AMD Linux GDDR7 ID | First graphics-stack reference, no arch named |
| IH 8.0 plus NBIF 7.10 | New blocks alongside |
| Micron D8FHL EOL | 2GB 28Gbps off catalog |
| 3GB survivors | Pricier, PRO plus laptop use |
What the pair means
AMD writes GDDR7 software while Micron thins GDDR7 supply. Opposite ends of the same memory transition in one news day.
Per the report, Micron is AI-first shift plus Crucial exit frames the thinning without abandoning consumers outright. Tighter cheap-GDDR7 supply plus pricier 3GB parts equals VRAM pressure on budget cards.
Our draft-34 VRAM health plus draft-99 RDNA 5 rumor drafts hold the background. This pair is the September 22 update.
- AMD: Software first, silicon later.
- Micron: Cheap lines out, dense lines stay.
- Net: Budget VRAM squeezes first.
VRAM read for buyers
8GB buyers face the squeeze directly: the 5060-class 4-chip pattern loses its cheap Micron option. 12GB via 3GB parts costs more, per board-partner leak reads in the report.
Next-gen Radeon watchers gain a real signal instead of a rumor: driver IDs precede launches by quarters. Pair with our Zen 6 roadmap patience thesis.

| Buyer | Read |
|---|---|
| 8GB class today | Cheap supply thinning, prices firm |
| 12GB class soon | 3GB path exists at premium |
| Next Radeon waiters | Driver prep is real, dates are not |
FAQ
What did AMD add?
Per the report via freedesktop, a GDDR7 VRAM identifier plus IH 8.0 and NBIF 7.10 blocks.
Does this name RDNA 5?
No, per the report. No architecture tied to the patch.
What did Micron kill?
Per UNIKO is Hardware via VideoCardz, all 2GB GDDR7 lines including the 5060 D8FHL part.
Why keep 3GB?
Per the report, denser configs for PRO plus laptop with premium pricing.
Is this one story?
Two reports, one transition. Combined here as the September 22 memory picture.
Are sources primary?
Mixed. Freedesktop lists plus Micron catalog are primary traces via relays. EOL motive reads stay outlet analysis.
Bottom Line
AMD codes for GDDR7 futures while Micron deletes the cheap present. Budget VRAM buyers should not wait for relief.
