GDDR
Traditional graphics memory used in consumer-grade graphics cards. It competes with HBM for wafer capacity, so when HBM demand surges, GDDR supply is compressed.
Timeline (last 90 days)
The total production capacity of the three major memory manufacturers Samsung, SK Hynix, and Micron is limited, and when HBM orders surge, the wafer and packaging resources originally allocated to GDDR are squeezed.
HBM has an extremely wide physical bus width (up to 1024 bits or higher), enabling it to deliver far greater memory bandwidth than GDDR at lower frequencies
The bandwidth of shared system memory is typically lower than that of dedicated GDDR video memory.
The core reason for the GPU price increases is that manufacturers have shifted a large portion of their production capacity toward HBM memory, causing a shortage of GDDR memory.
The cost per unit of bandwidth for HBM is far higher than that of GDDR or LPDDR.
