Gold Top CPU Mixed – Assorted Ceramic Processors with Gold Lids for Precious Metal Recovery
Buy mixed gold top CPU scrap – assorted vintage ceramic processors with gold-plated lids. Ideal for gold recovery, e-waste recycling, and precious metal refining. Contact us for bulk orders. Delivery by air, land & sea worldwide. Standard & express shipment available.
Our Gold Top CPU Mixed lot consists of assorted vintage ceramic processors that feature a visible gold-plated lid (heat spreader or cover). This category includes CPUs from Intel, AMD, Cyrix, IBM, and other manufacturers from the late 1980s through the late 1990s. These gold-top processors are highly sought after in the precious metal recycling industry because they contain substantial recoverable gold in the lid, pins, internal bonding wires, and thick-film traces on the ceramic substrate.
The “gold top” designation refers to the visible gold-plated surface on top of the CPU, which immediately indicates higher gold content compared to plastic CPUs or even some ceramic CPUs with nickel or tin lids. Mixed lots typically include a variety of models, speeds, and brands, offering refiners a consistent stream of gold-bearing material.
What Does “Gold Top CPU Mixed” Include?
| CPU Type | Typical Examples | Gold Lid | Gold Pins | Relative Gold Value |
|---|---|---|---|---|
| Intel Pentium (P5, P54C, P55C) | Pentium 60/66/75/90/100/120/133/150/166/200/MMX | Yes | Yes (273-387 pins) | Very High |
| Intel 486 (Ceramic) | 486DX, 486DX2, 486DX4, 486SX | Some models | Yes | High |
| Intel Pentium Pro | Pentium Pro 150/166/200 (gold cap on package) | Yes (under cap) | Yes | Highest |
| AMD Ceramic CPUs | Am486, Am5x86, K5, K6 (ceramic versions) | Yes | Yes | High |
| Cyrix Ceramic CPUs | 486DLC, 486DRX, 6×86 (ceramic) | Some | Yes | Moderate-High |
| IBM/Cyrix | Blue Lightning, 6×86 | Some | Yes | Moderate |
| IDT WinChip | C6 ceramic (rare) | Some | Yes | Moderate |
| NexGen | Nx586 (ceramic) | Yes | Yes | High (rare) |
| Texas Instruments | 486 based | Some | Yes | Moderate |
Gold-Bearing Components in Gold Top CPUs:
| Component | Gold Content | Recovery Method |
|---|---|---|
| Gold-plated lid (top) | Moderate to High | Mechanical removal (heat + prying) |
| Gold-plated pins (leads) | High (especially high pin count) | Depopulation or chemical stripping |
| Gold bonding wires (internal) | Very High | Chemical refining (aqua regia, etc.) |
| Thick-film gold traces (ceramic) | High | Chemical refining after crushing |
| Gold-plated heat spreader (under lid) | Moderate | Same as lid removal |
Typical gold yield for mixed gold top CPUs: 0.8 – 2.0 grams per kilogram, depending on the proportion of Pentium Pro, Pentium, and 486 models.

Laboratory assaying and precious metal analysis
-
Educational demonstrations (e-waste gold content)
Available Quantities:
-
Small sample lots: 1–5 kg (for testing and assay)
-
Wholesale lots: 10 kg, 25 kg, 50 kg boxes
-
Bulk pallets: 200–500 kg palletized
-
Container loads: Full 20 ft or 40 ft containers (by arrangement)

Typical Composition of a Mixed Lot (Example):
| Category | Approx. % of Lot | Gold Yield Relative |
|---|---|---|
| Intel Pentium (gold top) | 40–50% | High |
| Intel 486 ceramic (gold top) | 20–30% | Moderate-High |
| AMD ceramic (gold top) | 10–15% | Moderate-High |
| Cyrix / IBM / others | 5–10% | Moderate |
| Pentium Pro (gold cap) | 0–10% (seasonal) | Very High |
| Plastic CPUs (rejected) | <5% (sorted out) | None (not included) |
Quality & Condition:
-
Sold as non-functional scrap – no testing for electrical operation
-
Lids must have visible gold plating (not nickel, tin, or bare copper)
-
Pins may be bent, oxidized, or slightly missing – still counts for weight
-
Ceramic may have minor chips or cracks – does not affect gold recovery
-
Some units may have original thermal paste or adhesive – included in weight
-
No plastic CPUs, no epoxy packages, no PGA with nickel lids (we pre-sort)
-
Heatsinks and fans removed unless still attached naturally
Pricing Considerations:
-
Based on weight (kilograms or pounds) and current gold market price
-
Premiums for lots with higher Pentium Pro or rare CPU percentages
-
Discounts for heavy oxidation, missing pins, or damaged lids
-
Assay certificates available for large lots (third-party laboratory)
Processing Tips for Refiners:
-
Visual sorting – Separate by brand/series for optimal processing (Pentium Pro separate from standard Pentium)
-
Lid removal – Heat with hot air gun (200-250°C) to soften adhesive, then pry off with a blade or screwdriver
-
Pin depopulation – Use decapsulation tool, heat, or chemical stripping (professional methods only)
-
Ceramic processing – Crush and use aqua regia or cyanide leaching (requires proper licensing and facilities)
-
Safety protocols – Always use fume hoods, PPE, and comply with local e-waste and chemical disposal regulations
Comparison – Gold Top vs Other CPU Scrap Types:
| Scrap Type | Gold per kg (Typical) | Price per kg | Processing Difficulty |
|---|---|---|---|
| Gold Top CPU Mixed | 0.8–2.0 g | Moderate-High | Moderate |
| Green Fiber CPUs (plastic) | 0.1–0.3 g | Low | Easy (but low yield) |
| Ceramic no gold lid | 0.3–0.7 g | Moderate | Moderate |
| Gold plated pins only | 2–5 g (per kg pins) | High | Easy (stripping) |
| Pentium Pro (full) | 1.5–3 g | Highest | Moderate |
| Gold finger cards | 1–3 g (per kg fingers) | Very High | Easy (stripping) |
