Now we know why the PlayStation 5 revision is 300g lighter
Austin Evans did a teardown of the PlayStation 5 revision and found out where the 300g was saved
Sony have greatly reduced the heatsink the the new PlayStation 5 (CFI-1100B) revision, compared to the launch model (CFI-1015B)
New fan
The revision also features a new design on the fan, it has the exact same weight and manufacturer as the model they compare withThe launch model came with 3-4 different fan models, made from different manufacturers. Which is a common practice in the industry, to get enough parts to product a product. They'll provide a specs list of requirement and dimensions, then manufactures will get as close as possible to these specs. This also means the design and brand might vary slight, even when the product have the exact same model number
Thermal heat
When comparing the thermal heat exhausted in the back, the new revision is giving out about 3°C more heat
Improved screw
Sony have also improved the screw in the bottom, by adding some rubber grip to the end. Making the screw easy to add / remove using your fingers, without the needs for toolsThere have also been complaints about the screw getting really hot, so the rubber should also make it safer to touch
Antenna cables
The new revision only have two antenna cables, compared to four on the release model. So there have been some changes here as wellAustin didn't do any Wi-Fi testing, so if there's been any change to Wi-Fi performance we can't say
