Discord Kills Electron for Rust, PC RAM Prices Hit $48
DDR5 contract prices reach $48 as makers shift capacity to AI memory
Stanislav Vishnevskiy posted a screenshot to X on November 4, 2026 showing an internal build of Discord Phoenix running at roughly 290.2 MB of RAM with two accounts active. The app he wrote in Rust uses the GPU-accelerated GPUI framework. The current Electron client routinely sits above 600 MB at idle and has been reported to exceed 4 GB under stress, which is why some users had to install experimental restart helpers.
Discord has used Rust since 2018 for parts of its infrastructure and voice stack, so the language was not new to the company. What is new is the plan to move the whole desktop client over. Electron ships a full Chromium engine inside every copy of the app, and that bundled browser is the source of the overhead. GPUI draws the interface natively instead.
On mobile, Discord will stop using React Native. The apps will keep native interfaces but share app code with the desktop version through Rust. Vishnevskiy said user testing should start soon but gave no public release date.
The timing is unusually bad for bloated software. The DRAM market is facing a structural squeeze as Samsung, SK Hynix and Micron shift fab capacity toward High-Bandwidth Memory for AI data centers. TeamGroup CEO Chen Ching-wen told investors on November 2, 2026 that contract prices for 16Gb DDR5 chips rose from $8.70 in October 2025 to $48 by September 2026.
That is more than a 550% increase in a year. Chen said the shortage will persist through 2027 and that market balance is unlikely before the second half of 2028. He described scenarios where money will not buy memory at all, as major makers have already allocated much of their 2027 output to HBM.
Spot market rates sit 30% to 50% above contract prices. J.P. Morgan Global Research had estimated a 400% price rise from early 2024 to the end of 2026, while TrendForce projected 10% to 15% quarter-over-quarter increases for conventional DRAM in Q4 2026.
OpenAI CEO Sam Altman has argued that keeping DRAM sitting idle in a personal computer is a poor use of scarce supply, favoring cloud utilization instead. With conventional DRAM becoming both expensive and hard to find, developers have less room to ship heavy frameworks.
