T4200 internal architecture?

Does anyone know if the T4200 is a 'real' C2D CPU or is it really a Pentium Dual-Core?

Docs I've found on intel.com are kind of non-committal.

thanks

 

It uses the same Wolfdale/Penryn silicon that is the basis for all of Intel's 45nm Core 2 processors.

 

The Pentium T-series is in a sense a "defective" Core 2. When a Core 2 die comes off the line and doesn't pass the quality specs for a Core 2 Duo processor, then they disable some of the cache, lock the multiplier to it's most stable frequency, and badge it as a lower class processor such as a Pentium T4200.

 

That is debatable and anecdotal at best.

 

That's why I said "in a sense". It's much harder to explain than that. But that's basically what they do.

 

But you, I, and everyone else here don't know if they are even binning their processors, let alone how it is done on the Core 2 assembly line. Sure you might assume that the extreme edition cores are the pick of the litter, and they probably are, but the core of a T4200 has the possibility of being better. When they do bin, manufacturers are rarely very thorough and most of the time the parts are very conservatively rated. These days even the lowliest revision E0 chip from Intel will overclock higher than the fastest stock Core 2 processor frequency. At that point why would Intel waste a lot of time and effort to test the performance envelope of many processors on the assembly line? On top of that mobile cores are commonly considered to be binned higher desktop counterparts due to the power and heat constraints of their application, even though on average they are running at much slower speeds.

 

I would pretty much agree more with Trottel on the analysis.
