Although many people expect each generation of GPUs from both AMD and Nvidia to be fleshed out with a wide range of products, nobody likes the curtains to open before the stage is properly set. Unfortunately for Nvidia, that seems be exactly what’s happened with its rumored GTX 990M mobile graphics chip, the existence of which Wu Haijun, CEO of Chinese computing manufacturer Hasee, revealed during a recent conference.

Haijun didn’t just confirm that the chip exists however, he went even further, saying that many companies would be releasing laptops built using the powerful new mobile GPU before the end of this year. That means that we are looking at a Q4 release date for the GTX 990M, as per NotebookCheck.

And that’s not all the information that’s been revealed — though the other informants aren’t quite so respectable. From sources said to be “independent industry insiders,” we’re told that the GTX990M is code-named N16E-GXX and will be built around the Maxwell GM204 architecture. Its TDP is said to vary between 100 and 185 watts.

However, the big rumor is that this chip won’t use the mobile PCI express module (MXM) as with traditional laptop graphics solutions, but will be soldered straight to the motherboard. It’s not clear why that would be at this time, or even if it’s true, but it could be because of the variable power requirements, or a potentially larger than normal cooling solution.

The guys who originally spotted Mr Haijun’s slip-up during the Hasee conference have speculated that performance should be similar to the 980M SLI, but that is entirely guesswork, no matter how well informed.

Does the news of this late-in-the-year release make you want to hold off buying anything over the next couple of months?

Apple’s rumored larger iMac could ship with more powerful M2X processor

If Apple's recently relaunched iMac desktop with the company's M1 processor is still too small for your needs, you may soon be in luck. Apple is said to be working on a larger all-in-one desktop that will replace the current Intel-powered iMac in its lineup, and the model could get an even larger screen size, similar to the size boost from the 21.5-inch Intel-powered iMac to the current 245-inch M1-powered model.

"I absolutely still believe that a larger, redesigned ‌iMac‌ to replace the Intel 27-inch models is en route," Bloomberg reporter Mark Gurman wrote in his Power On newsletter, according to a Mac Rumors report. "Apple increasing the screen size of the smaller model from 21.5 inches to 24 inches seems to indicate that the 27-inch model could see a size increase as well."

A former Apple engineer reveals the secret 10-year plan behind the M1 chip

Rumors of Apple’s switch away from Intel processors existed for years before Apple announced the move to the world in June 2020. But according to a former Apple engineer, the company was making moves in this area long before most people realized it.

In a detailed Twitter thread, Shac Ron, who worked as a Senior Kernel Engineer at Apple from 2007 to 2017, shed light on the history of the M1 chip and Apple’s efforts to develop their own alternative to Intel processors. The thread came about in response to a tweet from machine learning expert David Kanter that claimed M1’s performance is much more to do with its cache than its architecture.
