AI GPUs

AI GPUs are graphics cards judged on memory capacity and parallel compute throughput rather than on the frame rates they push in games. The people who read this page tend to be training or fine tuning models, running inference on a machine under their own desk, or pushing large batches of images and text through a pipeline that would take days on a processor alone. The card does the same arithmetic thousands of times at once, which is what turns an overnight job into a coffee break.

This page sits under Graphics Cards and covers the compute side of that parent category. The rest of the tree is split by brand, one page per manufacturer, so a card named for its maker belongs to a sibling page instead. What separates the cards discussed here is a short list of numbers: VRAM capacity in GB, memory bandwidth, the count of parallel compute cores, and the rated board power the card pulls under a sustained load.

VRAM decides what runs at all. Model weights plus the batch being processed have to fit in memory before a job starts, and a card that falls short does not run the workload slowly, it refuses it. Bandwidth decides how fast that data moves once loaded, which is where a card with generous memory on a narrow bus stalls on data heavy work. Board power is the third number and the one buyers skip. Compute jobs hold a card near full draw for hours rather than the minutes a game demands, so the PSU needs headroom above the rated figure and the case needs airflow that keeps the card off its thermal limit.

Someone running a small language model locally for a side project has a different shortlist to a team training a custom model against their own dataset, and the gap between them is measured in VRAM more than in core count. Buying past the memory the job needs takes money away from cooling and the power supply, which is where the same budget does more. Anyone here for frame rates in current game titles wants the brand pages under Graphics Cards instead, where cooler design and clock behaviour are tuned around short bursts of load.

Buying in Pakistan

Mega Computer delivers nationwide across Pakistan and accepts cash on delivery and online payment, with a showroom in Karachi for buyers who want to inspect a card in person. Power conditions matter for this class of hardware more than for most: a card held near full draw for hours is unforgiving of a supply that sags, so a machine on an unstable line wants a UPS and a PSU rated well clear of the card. Keep the invoice and the retail packaging, since GPU warranty claims in Pakistan run through the local distributor and both are usually asked for.
