Dropping it onto the digital scale yields a substantial 51.9g. This is not some delicate mobile silicon. Resting it against the calipers, the fiberglass substrate measures roughly 52.5mm by 45mm. The integrated heat spreader, or IHS, is expansive and features those classic heavy-duty Intel locking wings on the sides.

The silicon is perfectly intact, but you can see the slight scuffing and discoloration on the nickel-plated copper IHS from years of thermal paste application and heavy mounting pressure.
Flipping the artifact over reveals a sea of 2011 gold contact pads. But what really catches my eye is the paper sticker slapped right in the middle of the surface-mounted capacitors. It reads F撕毁无效 alongside dates checked for 2025 11 12. This translates roughly to "void if torn." This tells a fantastic story about the journey of this specific unit.
Diving into the technical weeds, this SR2R6 is a 14nm Broadwell-EP chip. Despite the relatively low base clockspeed of 2.1 GHz, this was a serious compute node component designed to run 24/7 in dense server racks. It packs 8 cores and 16 threads, accompanied by a very healthy 20 MB of Intel Smart Cache.
The thermal envelope is impressively efficient for its era. Intel rated this at an 85 W TDP. When you consider the physical size of the die and the massive surface area of the IHS, dissipating 85 watts is trivial, meaning this chip ran incredibly cool even under full synthetic load.
The architecture interfaces through LGA-2011-3 (also known as Socket R3) and supports quad-channel DDR4 ECC memory. The memory controller was arguably one of the most robust features of the Broadwell-EP lineup, allowing huge arrays of registered DIMMs to be heavily utilized by virtual machines.
Broadwell is often considered the forgotten middle child in the desktop enthusiast world, wedged awkwardly between the legendary Haswell and the ubiquitous Skylake. However, in the server space, Broadwell-EP was an absolute titan.
The funny thing about these Xeon E5 v3 and v4 chips is their bizarre afterlife. Because hyperscalers like AWS, Google, and enterprise IT departments upgrade on strict hardware lifecycles, millions of these perfectly functional 8-core and 12-core processors were pulled from racks and dumped into the secondary market.
This created a legendary subculture in the budget PC gaming community. Chinese motherboard manufacturers began engineering heavily modified "X99" motherboards using salvaged server chipsets. Enterprising builders would buy a chip exactly like the one we have here for the price of a fast food meal, slot it into a mutant Chinese motherboard, and suddenly have an 8-core workstation that could legitimately run modern games and rendering software.
The FPO (Finished Process Order) batch code is J802B436. The first letter "J" tells me this silicon was packaged at Intel's facility in Malaysia. The next three digits "802" indicate it was manufactured in 2018, specifically week 02.
This is a fascinating data point. Intel officially launched the Xeon E5-2620 v4 in Q1 of 2016. The fact that this specific unit was rolling off the line in early 2018 proves just how long-lived these enterprise contracts were. Intel was still pumping out Broadwell silicon well into the Skylake-SP era to fulfill legacy replacement cycles for massive server farms.
Furthermore, the Chinese warranty sticker on the back confirms its post-enterprise life. Once it was retired from its original air-conditioned server room, it was bought in bulk by an e-waste recycler or refurbisher in Shenzhen, tested, stickered with that 2025 warranty expiration, and likely sold on AliExpress or Taobao to a budget builder. It is a perfect artifact representing the global silicon recycling ecosystem.
