(Pocket-lint) - Xbox's all-singing, all-dancing next-generation games console, the Xbox Series X, will be released at the end of 2020. But, did you know that there's another, cheaper next-gen machine that could join it in stores?

An Xbox Series S has been rumoured for a while, mostly under the codename of Lockheart, and rumours suggest that it could also launch this coming holiday period.

Here then is everything you need to know about the Xbox Series S, based on the speculation so far.

What is Xbox Series S?

When Phil Spencer first teased what was coming next from Xbox, during E3 2018, he suggested that there could be more than one machine on the horizon.

Since then, the company has officially confirmed the Xbox Series X, which will be released "holiday 2020". However, considering that will be a full-on powerhouse of a console, likely with a price to match, there has been plenty of chatter to suggest that we'll see a cheaper, less-specced model too.

That started with the codename "Lockheart".

In December 2019, it was suggested that two new consoles were in development: Anaconda and Lockheart. The former is thought to be Series X (also previously known as Project Scarlett) while the other is touted as the Xbox Series S.

It will reportedly be a trimmed back replacement for the Xbox One S and/or Xbox One X (which has recently been discontinued), with less power than the Series X but with the ability to play games in (almost) 4K HDR.

We don't yet know what it will look like, but we hope that it is something like the excellent mock-up render made by Reddit user JiveDuder (above). Certainly, a photo of what is claimed to be the controller for it (which appeared on Reddit before being pulled) suggests something along those lines.

The same controller was posted by Zak S on Twitter, who claimed to have been able to purchase it online. He added video too.

Xbox Series S specs

  • 4 teraflops of graphics processing power
  • 1440p gaming in up to 60fps
  • Ray-tracing support
  • SSD storage
  • No disc drive

We don't yet know the full specifications of the Series S, but rumours point to it having 4 teraflops of GPU processing power. That's dramatically lower than the Series X (which has 12 TFLOPS) and even lower than the Xbox One X (with its 6 TFLOPS). But, if you consider that the PS4 Pro has just over 4 TFLOPS of GPU power, you can see that it's still very impressive for an "entry-level" machine.

As a next-gen console, the Xbox Series S is said to also sport ray-tracing abilities (like its more capable sibling) and SSD storage for faster loading and instant-on game resumption.

Its maximum resolution for gaming is claimed to be 1440p, rather than full, native 4K, and will run games in up to 60fps.

Another rumour doing the rounds is that the Series S is that it will come without a physical media drive. The Xbox Series X will have a 4K Blu-ray player - much like the One S and One X - but the Series S is said to more like the Xbox One S All-Digital Edition and therefore dependent on digital downloads and streaming.

Xbox Series S release date

  • August unveiling possible

The popular train of thought is that the Xbox Series S will be made available alongside the Xbox Series X this holiday season, although that is far from confirmed.

Having not been mentioned in July's Xbox Game Showcase event online, we'll hopefully find out more in August, as persistent rumours suggest.

Xbox Series S price

  • Possibly around £300

This is probably the biggest open question about the machine at present: how much will it cost?

If Xbox deems it necessary to have a second, cheaper Series console available, it means the larger, better specced next-gen machine will cost a packet. And, if it plans to continue to sell the Xbox One S (the only current console not discountinued), we imagine the Series S will sit somewhere in the middle of those.

That basically means it will be between £250 and £350.
