whats the diference between the canterwood and the springdale?

[DR. YT]

they seem like the same thing to me.

PAT is the only performance difference that I'm aware of, I think the chips are identical other than that.

P.S. hey Docyt glad to see you figured out the code for your sig !

[DR. YT]

intels like a weird old lady with to mutch money if thats true. why not just have released the springdale.

here ya go ! from Vr-Zone

Intel 875P MCH is built on the FCBGA package that allows Dual Channel 4 layers PCB and is 37.5mm2 in size and has 932 pins count. Interestingly, 875P and 865P/PE/G share the same core and the only difference is that 875P falls on the right side of the manufacturing curve.

Intel has specially selected the top quality chips that falls on the right side and separate from the rest and ran through a series of comprehensive tests to ensure robust operation for the 875P chipsets. As for the rest, they would be branded as Springdale chipsets and sold off cheaper. The chipset timings of the 875P are improved to allow faster memory access and lower latency therefore we can expect 875P to be faster than 865PE/G.

And some more on the topic from Lost Circuits:

Whoever thought that the main differences between the Canterwood and the Springdale chipset are confined to yield issues or else just another marketing plot by Intel will be disappointed to learn that the two chipsets are somewhat different. On the grounds of the silicon itself, there are very little differences between the two chipsets, the most prominent being the already mentioned omission of PAT and the lack of ECC support in the case of Springdale.

If we look at the packaging, the picture changes ever so slightly. The Canterwood features the same 1005 balls as the Granite Bay chipset on the same footprint of 42.5 x 42.5 mm square. The i865G features a total of 932 pins within a 37.5mm x 37.5 mm footprint. Keep in mind that this is the VGA version, featuring the additional ball count for the internal Intel Extreme Graphics2. Still, as far as we know, the ballout is the same for all three versions of the i865 with the restriction that the "P" versions have a higher number of dummy balls a.k.a. no connects than the 865G. A part of the lower ball count can be attributed to the omission of ECC, which, just for the management of the checksum already saves a minimum of 8 pins / channel.

The majority of contacts on both Canterwood and Springdale are Vcc and Vss (power and ground) and that is where additional pin savings can be achieved. Hence, one might also argue that it is mostly better shielding and power distribution that sets the two chipsets apart, not only with respect to signal quality but also in terms of manufacturing cost for the chipset itself..

After investigating it a bit further, MS is half-right. The i875P features 12 more Vcc pins than does the i865 (56 vs 44). However, the i865 series considerably more Vss pins than the i875P (292 vs 252). So, the i875P possibly gets a steadier voltage where as the i865 has better shielding.

Which could mean that the i875P may not need as much extra juice going to the chipset for breaking 300MHz+ FSBs. Since it also has less grounding pins, that may be a good thing. The i865 may be able to withstand slightly more juice (pending adequate cooling) than the i875P for hitting the same plateau.

To what extent these facts actually contribute to the overclocking abilities of each chipset, I do not know exactly. I'm sure someone will figure it out. ;)

ok so. so do you guy think the differences you discribed realy constitute calling them two different chipsets or maybe it would have more apropreit to have a delux ot ultra style naming for the two.

They're not i850E/i845PE different, but they're different to the extent in which Intel is marketing them. Now, as far as what they're charging for the i875P compared to the i865PE, that's a different story.

We'll know more in a few weeks if the i875P is really worth the extra dough over the i865PE. Given some more BIOSes, IAAs/INFs, the matter should sort itself out.

Right now, though, the i865PE looks rather enticing. But, that's just my opinion.
