This listing is for a genuine Rise mP6 266MHz processor (Socket 7).
✔ Tested and confirmed working
✔ Clean condition (see photos)
✔ Carefully stored
The Rise mP6 series represents a unique chapter in CPU history, as one of the lesser-known competitors in the x86 market during the late 1990s.
Compared to more common Intel and AMD chips, Rise CPUs were produced in much smaller quantities, making surviving units increasingly difficult to find today.
This 266MHz version is especially sought after by vintage PC collectors and Socket 7 enthusiasts.
Availability is limited — once sold, it may not be easy to find another in similar condition.
Perfect for:
- Vintage PC builds
- CPU collectors
- Retro computing enthusiasts
🔥 RISE 266 — One of the Rarest “Lost x86 Era” CPUs | NEW Condition | A True Collectors’ Piece 🔥
The RISE 266 is widely considered one of the hardest x86 processors to obtain, even among long-time CPU collectors.
This is not just another vintage chip — it is a true relic from the final years of the multi-vendor x86 era, a piece that simply cannot be replaced once it disappears.

⭐ Extremely Rare — A CPU Serious Collectors Know About, But Almost Never See
The RISE 266 had extremely limited production, minimal retail presence, and most units never entered normal distribution.
After RISE Technology ceased operations in the early 2000s:
Remaining stock vanished
Engineering samples were scrapped
Circulating pieces became almost nonexistent
Among collectors, it is well known that finding a complete, clean RISE 266 is almost pure luck.

⭐ Historic Significance — A “End-of-Era” x86 Processor
The RISE 266 represents the final wave of competition before the x86 market consolidated into a dual-vendor ecosystem.
It stands as a symbol of:
The last independent x86 challengers
The late-1990s experimental CPU era
A short but fascinating chapter of PC history
A technology path that ended abruptly and will never return
Collectors often describe the RISE 266 as a true discontinuity piece —
once missed, it’s gone forever.
---
⭐ Why Collectors Value This CPU
The RISE 266 holds strong appeal in the collecting community because it is:
✔ Extremely rare
✔ Historically meaningful
✔ Practically impossible to replace
✔ A standout display piece in any vintage CPU lineup
For many collectors, a 1990s x86 collection feels incomplete without it.

⭐ Investment Potential
Vintage processors with low surviving quantities tend to appreciate steadily over time.
The RISE 266 is one of the very few chips where:
Prices have never truly dropped
Supply is near zero
Owners rarely list them again once acquired
This makes it a strong long-term collectible for serious enthusiasts.

⭐ Condition
Brand New / Unused
Pins are straight and flawless
Label is clean and sharp
Perfect for long-term storage or high-end display
Not recycled, not salvaged — true new-old-stock condition

⭐ If You’re Seeing This Listing, Consider It an Opportunity
This is a CPU that does not appear often — sometimes not even once a year.
Most collectors will never see a brand-new RISE 266 offered again.
For those who know its importance:
This is the moment to complete your collection.
