Core Viewpoint - The rapid increase in DRAM prices is likely to severely impact the PC gaming market, with DDR5 memory prices doubling in a short period, potentially leading to higher graphics card prices as well [2][6][8]. DRAM Price Surge - The surge in DRAM prices is primarily driven by the demand from AI companies and data center construction, which require massive amounts of DRAM to support modern AI models [2][3]. - Major DRAM manufacturers, such as SK Hynix, have reported that their DRAM, NAND, and HBM production capacities for the next year are fully booked [2][3]. Impact on PC Gaming Market - The shift in manufacturing priorities from DDR or GDDR memory to HBM for AI products is reducing the supply of consumer-grade memory, leading to price increases and supply difficulties for PC gaming components [3][4]. - The current situation mirrors the previous cryptocurrency boom, where manufacturers prioritized higher-margin products over gaming components due to limited production capacity [4]. Price Trends in DDR5 Memory - DDR5 desktop memory prices have seen significant increases, with popular 32GB DDR5-6000 kits rising from an average of approximately $125 to over $250 since mid-September [6]. - The price of 64GB kits has also surged from around $200 to nearly $500, while entry-level 32GB DDR5-4800 kits have jumped from below $100 to nearly $200 [6]. Potential Graphics Card Price Increases - Graphics cards are expected to be affected by rising GDDR memory prices, which share manufacturing capacity with other DRAM types [8][9]. - Current GDDR memory costs range from $2.50 to $3 per GB, with potential increases in costs translating to higher retail prices for graphics cards [8][9]. Cost Impact on Graphics Cards - The material cost for a graphics card with 16GB of GDDR memory is estimated to be around $40 to $50, with potential price increases of $25 to $40 for consumers if memory costs rise [10][13]. - If GDDR prices increase by 50%, the retail price of graphics cards could rise significantly, with estimates suggesting that the RTX 5070 could reach around $600 [14]. Future Market Predictions - The likelihood of graphics card prices dropping significantly below manufacturer suggested retail prices in the coming months is low due to rising DRAM costs [20]. - Consumers are advised to consider purchasing graphics cards sooner rather than later, as current prices are more favorable compared to future expectations [20]. Manufacturer Responses - Historical trends suggest that major manufacturers like NVIDIA and AMD are unlikely to sacrifice profits to stabilize prices, as maintaining profit margins is a key performance indicator for publicly traded companies [21].
