According to NPD DisplaySearch analyst Richard Shim, the display purportedly being produced for the smallest MacBook Pro features a resolution of 2,560-by-1600 pixels, compared to the current iteration's 1,280-by-800 pixel screen, reports CNET.
"The supply chain indications are that it's for a MacBook Pro 13.3 â not a MacBook Air," Shim said.
The analyst goes on to say Samsung, LG Display and Sharp are all churning out the new 13-inch panel to meet a higher initial volume compared to the 15-inch MacBook Pro with Retina display's launch in June. Stock of Apple's top-of-the-line laptop quickly dwindled as supply couldn't meet demand due to low display yield rates, and only recently has the company been able to catch up, with shipments now quoted at two to four business days.
"With 15.4 it's production of a few hundred thousand units versus one to two million for the 13.3," Shim said. He prefaced the estimates by noting volume depends on yield rates, noting that if the manufacturers are able to reach rate of 70, 80, or 90 percent, output of the 13-inch panel will likely be in the "million and a half range."
Shim also pointed out that the manufacturing capabilities of the three different suppliers can factor into how many displays will be ready for assembly.
"With Samsung, if you look at the new [Retina] iPad, they had fewer issues reaching the higher resolution requests from Apple," he said. "They were the first vendor to get to volume with that panel."
The production timeline could point to a fall debut for the rumored 13-inch Retina display-packing MacBook Pro, which is in line with previous reports that Apple would be launching the laptop in September.
Currently, the 15-inch MacBook Pro with Retina display is identified as "MacBookPro10,1," while the legacy 15-inch model is "MacBookPro9,1." The "10,2" identifier, first spotted in the logs of an online battery testing site, hints at a Retina version of the 13-inch laptop as the recently updated non-Retina version carries the "MacBookPro9,2" designation.
