Nvidia GTX 1180/2080 specs and performance: what should we expect?

There's surely not long to wait now. After two years with Nvidia's 10-series GPUs based on the Pascal architecture, we're finally due an upgrade. With several sources strongly suggesting a July launch date, Nvidia's next 'GPU King' may well be just around the corner, but what specs will it have? How powerful it be? In a market notorious for its often-accurate leaks, it's actually surprising how little we know, but there's enough information out there to at least give a broad overview of what we can expect.

First of all though, it's worth commending Nvidia on just how tightly its next-gen GPU line-up has been locked down. Even the name of the new series and the upcoming flagship remains unconfirmed. A GTX 1180 to kick off an 11-series product line-up? Or a GTX 2080 with a brand shift to a 20-series? In a world where specs often arrive months before release, even the name of the new line-up is unknown right now. Certainly, there's been nothing like the Pascal production line leak that confirmed 2016's 10-series branding and gave us a pretty good idea of the Founders Edition ID weeks ahead of the official reveal.

Only one publication - Wccftech - has released tentative specs and while there's a chance it's a genuine leak, there's enough ambiguity in there to suggest that it's a series of best guesses based on downsizing Nvidia's enormous Titan V processor - the only GPU currently available built using the next-gen architecture. In this sense, the 'leak' may well be inaccurate, but it may be 'ballpark' - after all, Nvidia has a proven formula whereby it starts with a big chip design aimed at its high-end datacentre customers, then shrinks it down, repurposing the same architecture for gamers, with reduced CUDA core counts and memory configuration, depending on the market sector. The only problem here is that Titan V is a product featuring a configuration with bespoke elements that'll never be released for gamers in its current form making guestimates on smaller, gaming-orientated versions hard to figure out. So what can we say about the next-gen architecture, for sure?
