Embeddium vs FerriteCore

Embeddium is a free Minecraft mod focused on rendering performance on the game client. It uses a multi-loader setup and is listed for Minecraft 1.16.5, 1.18.2, 1.19.2, versions 1.20.1 through 1.20.6, versions 1.21 through 1.21.1, and version 1.21.4. The mod does not require Sodium. Its stated scope is client-side use, so it is intended to run with the player’s Minecraft installation rather than as dedicated server software. Dedicated server support is not provided. Embeddium is available through Modrinth with a free plan. The main selection check is version matching: users need one of the listed Minecraft releases. The multi-loader designation indicates that it supports more than one mod-loading environment. Because its focus is rendering, it is aimed at installations where client rendering performance is the relevant need. Server operators should distinguish that client scope from dedicated-server requirements when deciding whether it fits their setup.

FerriteCore is a free, MIT-licensed coremod for Minecraft: Java Edition that targets RAM use. It reduces memory associated with block states, models, predicates, strings, voxel shapes and baked quads through a set of documented optimizations. Examples include replacing block-state neighbor tables with FastMaps, caching multipart model predicates, deduplicating model instances and reducing baked-quad memory. The project reports that individual techniques saved hundreds of megabytes in cited tests; one pack example showed post-garbage-collection memory moving from roughly 3.1 GB to 1.1–1.2 GB on the title screen. Several optimizations have no CPU impact during play, while some add load-time CPU cost. ThreadingDetector optimization is disabled by default because it may very rarely cause race conditions. FerriteCore supports Fabric, Forge, NeoForge and Quilt and is listed for Minecraft Java Edition versions 1.16.5 through 26.3, depending on loader builds. It is marked for both client and server use, and the maintainer recommends installing it on both because some optimizations apply server-side. Versions before 1.16 are not supported for backporting.
