Intel SP9xxx series

What differentiate them from the P9xxx and T9xxx series? they are Penryn cpus with a 1066mhz bus,6mb of l2 cache and a 25W TDP so they should be in the P9xxx class... So what is the purpose of the S then? Why are they in their one separate class? I just bought a SP9400 2.4 ghz that accordingly to the spec sheet on the intel website should work nicely in my ms-1651 but that doesn't tell me what the SP9xxx is supposed to be.

 

Apparently(wikipedia..) SP series processors use a different and smaller socket and are BGA (no pins).

Also, another similar thread.

 

I also believe SP CPUs have lower TDPs. (create less heat).

But I could be wrong, Intel's CPU finder will tell it though.

 

The SP-series differ from the P-series in a few ways:

1- They are considered "small form factor" which means they're physically smaller and intended for smaller, lighter laptops. The P- and T-series are 35mm x 35mm (1225mm sq) and the SP-series are 22mm x 22mm (484mm sq).

2- The SP9300 (2.26GHz) and SP9400 (2.4GHz) have 6mb of L2 cache memory, while the P-series models at the same clock speed (P8400 and P8600) only have 3mb of L2 cache.

3- Voltage is slightly different (lower for the SP-series) as follows:
SP9300/SP9400/SP9600- 1.05-1.15V
P8400/P8600- 1.00-1.25V
P9500 (same clock speed as SP9600)- 1.05-1.162V

4- Being smaller and having more L2 cache, the SP-series are about $75 more than similar P-series ($284 for SP9300/SP9400 vs. $209 for P8400/P8600, according to Intel's April 2009 pricing).

All SP- and P-series processors have the same 25W TDP. It's the SL-series (17W) and SU-series (10W) models that have lower TDP ratings...I had to look it up, I get them all mixed up, too!

 

Would the smaller die surface hamper cooling?

 

The die size is the same, the overall package is smaller. (wiki again)

IMO, this processor will either come with no pins, or will come with an adapter stuck on the bottom.

 

According to reviews of the Toshiba Tecra R10 and Dell Latitude E4300 (both of which use the SP-series), they run very cool.

 

make sure the cpu fits your machine before getting all excited about it.

 

Received it today. Works perfectly. Only problem is that I cant read the temps but the fan spin up when I stress the CPU so it's all good

 

Wait, wait, did you just buy and install a PGA SP9x00 processor? Was it in a standard Socket P notebook?

 

Since it's an ES model I figured out that they had to put pins on it to test it. I checked the pins against the one on my t7500 and they are exactly the same. So I think Intel put them there before sending the cpu to whoever was supposed to use it.
