The latest manufactured Playstation 3's will use less energy, therefore running cheaper and run cooler. The new model, codenamed CECH-2100A will use a 40nm graphics chip instead of the 65nm of the older CECH-2000A models. The use of the 40nm chip makes the PS3 cheaper for Sony to manufacture, and PS3 owners might notice their console sucking less power.
A Japanese website, PocketNews, provided a breakdown of power usage on the 2100A vs the 2000A:
| Model name: | CECH-2000A | CECH-2100A |
| XMB Menu (Still wallpapers) | 76W |
67W |
| XMB Menu (Main Theme) | 83-86W |
71W |
| FFXIII game event scene |
96-107W | 78-83W |
| FFXIII game menu | 83-84W | 74W |
| BD playback |
88-91W | 77-78W |
| Power Off (Remote Play Stand-by) | 9W | 9W |
(Note: Those still running an original 60GB PS3 use 160W playing a Blu-ray!)
Reducing the size will also make it less likely that units will overheat, which has been a concern and issue in the past. Other changes in the 2100A model include a simplified heatsink and a new, lighter power supply which weighs 412g, 30g less than the previous model.
Since its inception, Sony has never been able to make money on the Playstation 3 consoles themselves. With the redesign of the console with the PS3 Slim, Sony was able to close the gap between cost and price (even with the $100 price drop). By using cheaper technology in the latest 2100A model of the PS3 Slim, Sony may actually make a profit on the console.
