Last month Microsoft posted a lengthy article talking about what the upcoming Xbox Series X console can do. Today the company details the hardware inside the box that’s getting it done, including a custom eight-core AMD Zen 2 CPU running at 3.8 GHz and its powerful RDNA 2 GPU.


The technical jargon runs thick in Microsoft’s Xbox Series X technology post this morning, so much so that the company has created a helpful glossary to aid readers in navigating the various acronyms being thrown about. What you really need to know is that at this moment, the hardware inside the Xbox Series X is the most impressive I’ve seen in a gaming console, easily rivaling today’s more powerful gaming PCs. Here’s the full spec list Microsoft laid out this morning.

Between the CPU and GPU and the inclusion of a solid-state drive as primary storage, the Xbox Series X is ridiculously fast. Microsoft released a video comparing load times on the Xbox One X to the Xbox Series X and the difference is just ridiculous.

In another video posted today, Microsoft demonstrated the Xbox Series X’s much-discussed quick resume feature. Here’s how that works.

In case that’s not enough Xbox Series X information, the folks over at Digital Foundry have an excellent comparison of the Xbox One X and Xbox Series X, breaking down the differences in both console size and performance.

We know everything but the price now, while we’re still lacking major details about the PS5. Something has to be going on over at Sony right? I assume they were a bit blindsided by how hard Microsoft came out swinging and are trying to play catch up behind the scenes.
