Samsung Galaxy S25 matches iPhone 16, trails Pixel 9 in key feature

Google Messages sensitive content warnings

Samsung Galaxy S25 may disappoint you in terms of RAM configuration. The company is allegedly considering an awful downgrade for the next vanilla flagship. A wild rumor indicates 8GB RAM on the base variant, which will be terrible in 2025.

According to Jukanlosreve, Samsung may introduce the Galaxy S25 with 8GB RAM. The Plus and Ultra models could get 12GB RAM, while the Ultra gets 16GB in 1TB of storage. The decision is seemingly under consideration due to the low DRAM yield.

If Galaxy S25 comes with 8GB RAM, it would match the iPhone 16 but lag behind the Pixel 9. Notably, Apple Intelligence requires 8GB of RAM, settling a long-due RAM upgrade on base iPhone models this year.

Google also boosted RAM configuration, given the increased load of AI processing. While the rumor hints at 8GB RAM in the standard Galaxy S25, things may change as the leaker himself is unsure of the RAM-related input.

Galaxy S20, Galaxy S21, Galaxy S22, Galaxy S23 and Galaxy S24 feature 8GB RAM. Samsung brought up to 12GB RAM on select mid-range models. 12GB RAM as standard is a long-standing demand of Samsung’s smartphone users.

The next-gen flagships will be powered by Snapdragon 8 Elite and Gemini Nano AI models. The chipset can be optimized to perform well on 8GB RAM. However, Gemini Nano may not be able to deliver maximum performance without enough RAM.

Virtual RAM is just a gimmick. It has nothing to do with the phone’s performance or functional smoothness. The feature description itself reveals that apps will make use of virtual RAM to perform better for a reliable multitasking experience.

Samsung may change its plans regarding the RAM on the flagship model. Larger RAM is a requirement nowadays and the company must stay ahead of its key rivals, which are either matching or having an edge in key areas.
