# GPU Tier Rarities

Rarity is the backbone of power, pack value, and marketplace prices in Rig Rooms — a **crypto mining simulator** where better GPUs mean more hash rate in a **Solana play-to-earn game**.

## The five rarity tiers

| Tier           | Role in the meta                             |
| -------------- | -------------------------------------------- |
| **Common**     | Starter / filler hash                        |
| **Uncommon**   | Early upgrades                               |
| **Rare**       | Mid-game workhorses (shimmer presentation)   |
| **Ultra Rare** | High-end farm pieces                         |
| **Legendary**  | Top-tier hash and cosmetics (particle flair) |

Rarity applies across GPUs, boards, CPUs, PSUs, fans, cables, consumables, and more — not only graphics cards.

## Why GPU rarity matters

GPUs contribute most of a rig’s MH/s. Typical average GPU hash bands used in design (individual items vary):

| Tier       | Typical avg GPU MH/s (design band) |
| ---------- | ---------------------------------- |
| Common     | \~35.0                             |
| Uncommon   | \~57.8                             |
| Rare       | \~87.2                             |
| Ultra Rare | \~105.0                            |
| Legendary  | \~250.0                            |

A room of Legendary GPUs will usually dominate a room of Commons — but only if each rack stays **operational** and **Mint**.

## Consumable rarity boosts

Consumables are temporary 24h multipliers (max one per rig). Design bands:

| Tier       | Approx. boost |
| ---------- | ------------- |
| Common     | +20%          |
| Uncommon   | +77.5%        |
| Rare       | +135%         |
| Ultra Rare | +192.5%       |
| Legendary  | +250%         |

## Support-part rarity

Fans, cables, motherboards, and CPUs grant smaller hash bonuses that scale with rarity. Filling slots with higher-tier support parts is a quiet optimization lever after your GPUs are sorted.

## Pack odds & the chase

Packs weight pulls by rarity. Higher packs improve the odds of Rare+ / Legendary hits but still include variance. Check live odds in the [Pack Binder](https://rigrooms.com/guidebook/packs) and in-game pack detail screens.

**Happy Hour** (Wednesday evenings UK time) rotates specialty packs with limited stock — useful when hunting specific tiers.

## Marketplace pricing by rarity

Higher rarity usually means higher $COMPUTE list prices. Only **Mint** items can be listed. A 5% fee on sales routes to the burn wallet — scarcity pressure that matters when $COMPUTE trades as a **low market cap P2E coin**.

## Practical upgrade path

1. Get any operational GPU farm online
2. Replace Common GPUs with Uncommon / Rare as SP and packs allow
3. Keep PSU / fans / cables in step so racks don’t go offline
4. Target Ultra Rare / Legendary for flagship racks
5. Use the marketplace to buy specific upgrades instead of only gambling packs

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://rig-rooms.gitbook.io/rig-rooms-docs/game-systems/gpu-tier-rarities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
