Legendary tech-whiz John Carmack said that the Playstation 4 and the Xbox One are "very close" and that "they're both very good," according to Kotaku, leaving gamers wondering if both next-generation consoles will be more alike than expected.

While Carmack says he hasn't done enough benchmarking to be able to do a straight-up comparison between both next-generation consoles, he suggests they have a lot of commonalities, Kotaku also reports.

But several reports also reveal the PS4 might have an advantage over the Xbox One because of specs.

Digital Foundry, a software planning and implementation company, compared the GPU and memory architecture of the Playstation 4 and Xbox One, revealing the PS4 was between 17 and 33% faster than the Xbox One, according to Extreme Tech.

"The PS4 and Xbox One have radically different memory architectures, which will probably give the PS4 the lead early on, but performance might swing towards the Xbox One as developers learn how to use its ultra-fast SRAM effectively," Extreme Tech writes.

 "Of course, with the PS4 having a unified memory architecture, the performance crown could swing even further in Sony's favor."

And the Playstation 4 uses 3.5GB of its total 8GB RAM to run its operating system compared to the 3GB the Xbox One uses, the International Business Times reports, leaving gamers wondering if the PS4 will be a faster next-generation console.
