Sony has finally taken the wraps off the PlayStation 5's much anticipated specs. PS5 Chief Architect Mark Cerny, in a pre-recorded webcast, talked in detail about the various hardware choices in the console and how they affect gaming. On paper, the Xbox Series X looks to have the edge in this generation, but it is too early to conclude anything before testing out some real games.

The day we've waited for is finally here. While there's no revelation of the actual console design or gameplay, Sony's Mark Cerny did talk in detail about the internal architecture of the PlayStation 5. For this generation, Sony is focusing on a different approach to core clocks, improvements brought forth by AMD's RDNA 2 GPU, the SSD and expandable storage, and the Tempest 3D audio engine. We will discuss all those points in related articles but first, here are the specs.

So, on paper, the Microsoft Xbox Series X appears to be the more powerful of the two. But specs alone aren't indicative of the complete picture. For instance, the TFLOPs difference between the Xbox Series X and the PlayStation 5 is about 1.8, which is actually a full PlayStation 4 no less. Also, the Series X has 44% more ray tracing hardware than the PS5 albeit at lower clocks. This means Microsoft can emphasize more on real time path tracing while Sony looks more towards global illumination. 

Ultimately, it depends on how well developers can make use of the extra TFLOPs in the Xbox Series X. Until we see actual games in action, spec sheets can only tell half the story.

I am a cell and molecular biologist and computers have been an integral part of my life ever since I laid my hands on my first PC which was based on an Intel Celeron 266 MHz processor, 16 MB RAM and a modest 2 GB hard disk. Since then, I’ve seen my passion for technology evolve with the times. From traditional floppy based storage and running DOS commands for every other task, to the connected cloud and shared social experiences we take for granted today, I consider myself fortunate to have witnessed a sea change in the technology landscape. I honestly feel that the best is yet to come, when things like AI and cloud computing mature further. When I am not out finding the next big cure for cancer, I read and write about a lot of technology related stuff or go about ripping and re-assembling PCs and laptops.
