Memory bus (interface) width: Each DDR, DDR2, or DDR3 memory interface is 64 bits wide. Those 64 bits are sometimes referred to as a "line." Those 64 bits are sometimes referred to as a "line." Number of interfaces : Modern personal computers typically use two memory interfaces ( dual-channel mode) for an effective 128-bit bus width.
Bandwidth – Maximum theoretical memory bandwidth based on bus type and width. TDP ( Thermal design power ) – Maximum amount of heat generated by the GPU chip, measured in Watt. TBP (Typical board power) – Typical power drawn by the total board, including power for the GPU chip and peripheral equipment, such as Voltage regulator module ...
This number is generally used as a maximum throughput number for the GPU and generally, a higher fill rate corresponds to a more powerful (and faster) GPU. Memory subsection. Bandwidth – Maximum theoretical bandwidth for the processor at factory clock with factory bus width. GHz = 10 9 Hz. Bus type – Type of memory bus or buses used.
A graphics card/GPU with four 4‑Hi HBM stacks would therefore have a memory bus with a width of 4096 bits. In comparison, the bus width of GDDR memories is 32 bits, with 16 channels for a graphics card with a 512‑bit memory interface. [14] HBM supports up to 4 GB per package. The larger number of connections to the memory, relative to DDR4 ...
IGPs use system memory with bandwidth up to a current maximum of 128 GB/s, whereas a discrete graphics card may have a bandwidth of more than 1000 GB/s between its VRAM and GPU core. This memory bus bandwidth can limit the performance of the GPU, though multi-channel memory can mitigate this deficiency. [86]

This high bandwidth also means that GPUs can share memory over the NVLink bus, allowing an entire HGX board to present to the host system as a single, massive GPU. [9] Power delivery is also handled by the SXM socket, negating the need for external power cables such as those needed in PCIe equivalent cards.
