CPU Specs

While looking at Intel i7 CPU's I see names like Bloomfield, Clarkdale,
Gulftown, Prescott. What do they mean, and what's the difference bewteen chips
with the different names? Thanks.

Each of these is a the codename of the core used. All of those you
mentioned are various versions of the i7, except for Prescott which was a
core used in one generation of Pentium 4, ca 2004 or so, and was pretty
terrible.

Short answer:
Lynnfield = i7 860/870 - quad core desktop, socket 1156 (also i5-750, with
hyperthreading disabled)
Bloomfield = i7 920/930/940/950/960/965/975 - quad core desktop, socket 1366
Gulftown = i7 980X - six-core desktop, socket 1366
Clarkdale = i5 650/660/661/670 - dual core destkop, socket 1156

Arrandale and Clarksfield are the corresponding Mobile processor codenames.

Speaking generally, would it be correct that these codenames refer to
different types of fabrication processes?

Ie 113 vs 90 vs 45 nm process widths?

Isin't every new fabrication or process-width-size given a new code
name?

Only sometimes. There can be other differences - cache size, number of
QPI links, and other such things - that produce different codenames.
There isn't a consistent scheme for this at Intel, let alone across
different manufacturers. With Intel, the "mobile", "desktop" and
"server" versions of a design usually have different codenames, and
usually there's a "high-end server" version that has a codename of its
own.

It's also often the case these days that a change of process will result
in some implementation tweaks. For example, the "Penryn" 45nm chips were
notionally shrinks of "Conroe" in 65nm, but some of the floating-point
instructions also went significantly faster.

name?

There will be several codenames per process. Basically, Intel creates
new codenames when it seems convenient to them, rather by any fixed rule.

Not necessarilly.
Different code names could have the same fabrication process.

Ie 113 vs 90 vs 45 nm process widths?

Yes.

Everything is given a code name, i.e. Processor, Chipset, Boards, Server
Products, Networking

Thanks. Interesting that it too four or five days for any replies to show up on
my reader, and the original post never did show up. Anyway, any opinions on the
i7 920 processor? I'll be upgrading from a P4-3.2Ghz in this old system when I
have the new one built. I'd go higher on the CPU but they're out of my price
range right now. And once I get the system built with the 920, will I be able to
swap out only the CPU at a later date if I decide to? Thanks again.

The i7-930 is only $10 more, and slightly faster. But you are near the end of
that line, if you want to have expansion in the future go with another socket.
The i7-980 looks interesting, but I'm not sure if it will ever be available,
since the 980X (unlocked multiplier) version is getting all the attention.

For most people, I think Socket 1156 (ie the i7-860, whereas the i7-920 is
1366) is going to be a better choice especially for future upgrades - it's
got a better clock speed at base and turbo modes, and will likely have more
upgrade options in the future. 1366 is basically a server socket, and going
forward the consumer desktop options are going to be limited to particularly
high-end stuff.

I'm not sure that still applies if you overclock, though; friends who do are
gaga over the 920.

Hey Guys,
Its an excellent thread.
Designed to provide performance measurements that can be used to compare compute-intensive workloads on different computer systems, SPEC CPU2006 contains two benchmark suites
