How RigSync Actually Works - Under the Hood

How RigSync Actually Works - Under the Hood

I built three different ways to use RigSync because not everyone thinks about PCs the same way. Whether you're game-focused, budget-focused, or want to pick your own parts, there's an approach that fits how you actually work.

Here's the short version of what RigSync is: a PC-building web app that optimizes a complete build for your use case and budget — reaching the performance that matters while staying under budget, like a build consultant — then computes that it actually works, down to PCIe lane topology and whether a card physically blocks the slot next to it, shown in an interactive visualizer. Those two words — optimizes and computes — are the whole point, and I'll come back to them.

The Three Builders

Game-Based Builder: Tell it what games you want to play and at what resolution. It will build you a PC that hits your FPS targets without breaking your budget. Want to play GTA VI at 4K? It will tell you exactly what that's going to cost.

Custom Builder: More of a "I have $1200 and need a computer" person? Perfect. Tell it your budget and what you'll use it for, and it will optimize every dollar. Whether it's gaming, content creation, development, streaming, or work-gaming balance, the system prioritizes components that matter for your use case.

Component Browser: Want to pick parts yourself but need help with compatibility? Browse components with real filtering that actually matters, and it will make sure everything works together.

How It Actually Works

Behind the scenes, RigSync analyzes real benchmark data from games and applications. The FPS predictions come from real-world benchmark data, not theoretical calculations. The system builds in a conservative buffer, providing realistic targets rather than best-case scenarios.

There are always variables - driver updates, game patches, background processes - so the predictions account for typical real-world conditions. If RigSync estimates 120 FPS in your selected games, you should comfortably hit that target even with Discord and other common apps running.

The compatibility checking goes way deeper than "these sockets match." It checks physical clearances, power requirements, memory speeds, and even whether your motherboard's BIOS supports your CPU out of the box. It also maps the board's PCIe lane topology — how many lanes actually reach each slot and at what speed — and flags physical slot blocking, where a thick graphics card covers the slot beside it or a card overhangs into space another component needs. Those are the failures people usually discover only after the parts arrive.

Scoring works the same way, per use case. A gaming build values different parts than a streaming build, a content-creation build, or a professional workstation — video editing, 3D rendering, AI/ML, CAD, scientific computing, or virtualization. Each one weights CPU, GPU, memory, and storage differently, and GPUs in particular carry a separate score for each workload rather than a single gaming number. The same $1,500 gets you a different optimal build depending on what you actually do with the machine.

It goes past picking parts to sizing the whole machine. RigSync scales memory to the workload — a data-heavy AI or scientific box climbs toward large RAM as the budget allows, while a gaming box is capped so it never over-buys — and when there's budget left over, it spends on real capability (more memory to fit a bigger model or dataset) before paying for a sliver of extra speed. It also spends where the work is: on a GPU-bound job the money goes to the GPUs with a CPU sized to feed them; on a CPU-led job, the reverse. Ask for two, three, or four GPUs and it moves you to a workstation-class platform with the PCIe lanes and physical slots to host them, then runs the result through the same topology engine as any other build.

How is this different from an AI chat builder?

A lot of tools now claim to build you a PC with AI. Most of them are a chat prompt on top of a language model — good at suggesting parts, but they predict text, they don't verify hardware. Ask one for a build and it will confidently pair a motherboard and cooler that physically collide, or a graphics card and case that don't fit, because nothing in it actually checks.

RigSync optimizes and computes instead. It builds a complete, budget-optimized build for you, then runs every selection through the compatibility engine and the interactive topology visualizer, so a build it hands you is one that physically fits, powers on, and has the lanes each slot needs. The selection itself isn't a language model predicting a plausible parts list. It's an optimizer searching for the best combination your budget allows, and every candidate has to survive the compatibility and topology checks before you see it. That's the difference those two words were pointing at.

The Platform Architecture

Built with Blazor Server on .NET 8, the platform delivers fast, responsive recommendations while keeping all the complex calculations server-side. This ensures consistent, reliable performance across all devices.

All that compatibility checking and performance analysis happens in real-time as you make selections. The system constantly validates your choices and suggests optimizations without you having to think about it.

Continuous Improvement

The platform is in constant improvement. The database grows weekly as new hardware is added, and the compatibility and topology models keep expanding to new platforms. There's a reason catalog growth matters more than it sounds: every component is scored the moment it enters the catalog, so each new part isn't just another thing to browse — it's another candidate the optimizer can reach for. A bigger catalog doesn't only widen your options; it sharpens the builds, because there's a better-matched part to find at every budget. The engine gets better as the catalog grows.

Coming next: per-store price history so you can see when a part is actually a good deal, and an upgrade advisor that takes your current PC and a budget and tells you the single best component to change — including the full cost when a platform swap drags new parts along with it.

Beyond the technical improvements, I want RigSync to become a platform where people can learn about PC building without the intimidation factor. Expect more guides and tutorials over time.
