Apple announced Monday that it sold 3 million iPad mini and iPad models over the devices’ debut weekend. But the company did not break down those sales figures by model, so it’s hard to say how strong demand has been for either the iPad mini or the fourth-generation iPad.

According to the company, sales were twice as strong as the WiFi-only models of the third-generation iPad — the old New iPad, for those of you keeping track. That device’s WiFi models sold 1.5 million units in its first weekend in stores.

Apple did, however, hint that demand for the iPad mini was strong, with chief executive Tim Cook saying, “We set a new launch weekend record and practically sold out of iPad minis. We’re working hard to build more quickly to meet the incredible demand.”

Analysts expected the iPad mini to sell up to 1.5 million units in its first weekend, taking into account that the models that run on cellular networks aren’t coming for a few weeks.

The company said demand has already exceeded the supply the company set aside for initial distribution. Some pre-order customers, Apple said, have not yet received their devices but will get them later this month.

The iPad mini has a 7.9-inch screen and starts at $329 for the WiFi model. The fourth-generation iPad has a faster processor, sports the company’s new Lightning connector and has expanded LTE support for more networks around the world.
