An unknown S940 CPU. It probably fits in the category 'Opteron' and it might be a very early sample or a mechanical or thermal sample.

My sample has the markings 'SVDC DFM1' with 2050, 25.5 and B2 in the corners. With red there is a faint shade of what used to be the number 141. I've seen another... > Read more

Identical to my other AMD Opteron 1.6GHz in terms of OPN (Ordering Part Number). However, the laser-engraved printing on the CPU's is different. This particular CPU doesn't have the regular production-style printing on it.

My first AMD Opteron engineering sample on socket 940 . It boots up on my engineering sample MSI K8D Master-F but during P.O.S.T. it halts on the memory check. The check doesn't get past 514MB of RAM. Even when I swap out memory sticks and try different configurations it doesn't get past the 514MB... > Read more

The first generation of Opteron's. The 800 models are able to run in systems with eight (octa) CPU's. I have tested two of them in a MSI MS-9131 0B engineering sample motherboard and work great even despite they are not recognized correctly.

I obtained this CPU along with one nephew and four little brothers. All these CPU's are my first socket F samples so I didn't have any hardware to test it. Because I was interested whether the CPU's would work or not I bought suitable hardware. The result? A new server with four cores!

Unfortunately this CPU does not work. It never did when I got it and according to the heatspreader the CPU didn't work for a long time (or at all).

The regular line of Opteron 'Egypt'-cores had CPU's ranging from 1.8GHz to 2.8GHz. This particular Opteron 880 runs ar 2.4GHz and was a strong-performer when it was released in late 2005. The Opteron 8xx can run in 8 socket systems creating a (in total) 16-core system.... > Read more

This AMD Opteron 165 is based on the 90nm Denmark core. It one core and can run only in single-CPU systems.

A single-core 90nm Opteron that can run in up to two socket systems.

AMD released three versions in 2005:
1. OSA270FAA6CB with 95W TDP.
2. OST270FAA6CB with 85W TDP.
3. OSP270FAA6CB with 68W TDP.

AMD released a series of Opteron HE models (High Efficiency) that had a lower TDP (just 68W rather than 95W). With these models the 'Performance per Watt' (which was a marketing term that was popular at the time) increased quite a bit.

The fastest Opteron in the 8300-series with a Barcelona core. They range from 1.9GHz up to this 2.5GHz version. The initial release of AMD's Barcelona chip was in August of 2007. The 2.5GHz version appeared on April 9th, 2008.

In November 2008 AMD launched the 45nm Shanghai server CPU's. It was a refresh of the 'Barcelona' that were hampered with the TLB-bug and couldn't reach Intels' performance levels.

Not a bad CPU to have in late 2009. 12 cores that are based on the K10-core (read: Phenom II-performance) that work together to get the job done.

In 2009 AMD released the 6-core Istanbul. Models ranged from 1.8GHz to 2.8GHz with a few submodels that have the HE or EE label. HE stands for High-Efficiency and typically have a ~40W lower TDP.

The Opteron 6204 is a 3.3GHz 4-core part based on the Bulldozer core. Because it's based on the Bulldozer core it's performance can be disappointing in several use cases. With it's low-core count there is not much to compensate this lack of performance making it difficult to justify this CPU.

A 12-core CPU based on the Bulldozer core. Basically the AMD FX but used in a server platform. AMD's Bulldozer core was not the fastest out there but it's high-core count can clear the losses on low IPC a bit. Nevertheless it wasn't a succesful story since Intel just had the better overall product.

This AMD Opteron looks nice with it's grey / silver packaging. With that it differs from most CPU's: this CPU has a coreless package. It means that the organic substrate (PCB-like layer) is absent in order to reduce production cost, smaller packaging and less electric resistance. The latter also res... > Read more
