The Gigabyte GAMING OC is built on the NVIDIA RTX 4090, with 16,384 shading units and 24GB of GDDR6X memory on a 384-bit bus.
The memory is the reason to buy this card for AI work: a 70-billion parameter model quantised to 4-bit needs roughly 40GB, and anything that fits in VRAM runs an order of magnitude faster than anything that spills into system memory.
It draws up to 450W under load, so check your power supply has the headroom and the right connectors before ordering.
Cooling is the WINDFORCE triple-fan cooler.
