A weird CPU with a lot of questions. The CPU looks like an LGA1156 CPU but it doesn't have SMD chips on the back-side. Usually thermal or mechanical samples don't have these chips.

However, there is a picture or the original box indicating 315 pieces per box. The picture shows about 100 boxes stacked together. It's very unlikely that Intel made that much samples to be just thermal or mechanical sample. The box is labeled sSpec: SR26U.

The investigation continued when someone opened a CPU like this and found out that they consist of 4 CPU 'dies' like it would be an MCM chip.

Eventually 'Fritz' made die-shots (see here on flickr.com) of the chip in question. It doesn't really show an advanced chip architecture. It's more like identical rows of transistors (or resistors?) stacked next to eachother. > Read more

An unidentified AMD 'AM3' CPU. I have a lot of missing information about this CPU since it won't boot up. It has markings '2950' and '-15x' but no indication about it's core, frequency or whatsoever.

If anyone has more information on these please leave a comment below . > Read more

The first Cyrix 6x86 CPU that Cyrix released was the 120+ running at 100MHz. It was announced in October 1995. To put it in timeframe: the fastest x86 CPU was the Pentium 133 and the AMD K5/90 wasn't available until late March 1996.

After the release of the 120+ Cyrix also released the slower 90+ at 80MHz. Both the 90+ and 120+ use the M1-core that was manufactured using the SGS Thomson 3M process at 650nm. Cyrix switched to the M1R-core (IBM 5M process at 650nm) in mid 1996 for the 6x86 133+, 150+ and 166+ > Read more
