Samsung’s K4ZAF325BC-SC20 used for the Battlemage B580 are being listed by most sellers around ~$8 per memory module (IC) or $4/GB from new (not refurb, used etc…). If we factor in a hypothetical 30-50% volume discount then it drops to $2-2.8/GB for bulk orders by Intel.

The memory market is very competitive and commoditized so pricing for other 20Gbps 16Gb modules are likely very similar including the SK Hynix H56G42AS8DX-014 modules by RDNA 4 cards.

(Extra info)

According to Trendforce in June 2024 GDDR7 carried a 20-30% premium over GDDR6. The Q1 GDDR7 pricing premium is unlikely to have significantly changed since then, at least not for the worse as memory usually get cheaper as the technology matures. Any claims of GDDR7 costing NVIDIA as much as +$5-8 a GB is probably inflating the true cost for massive buyers like NVIDIA (only customer rn).

NVIDIA, Intel, and AMD also deal directly with GDDR memory producers like SK Hynix, Micron and Samsung so their purchase price is most likely significantly lower than the average spot price quoted by Trendforce.

AliExpress pricing for Samsung GDDR6 8Gb ICs which fall in the $2-3 range. This is close to the ~$2.3/GB average spot price quoted by Trendforce (via DRAMeXchange).

(A note on GDDR IC variance between generations)

It’s interesting that the RX 9070XT and 9070 use the exact same memory as all RDNA 3 cards, so AMD likely got a good deal and/or reused the memory for RDNA4 to help AIBs save on R&D.

This is in stark contrast to the 30 and 40 series that’s using GDDR6 and GDDR6X (two types for 40 series and multiple for 30 series). With 50 series so far only 2 types have been used.

I hope this info can form the basis of GDDR pricing discussions with less inflated pricing estimates.
