Core i5 and i3 Branding

[philbar71]

The important take away points are as follows:

1) The new brand is Intel Core. There will be three derivatives: Core i7, Core i5 and Core i3.

2) The Core 2 Duo and Core 2 Quad branding will eventually disappear.

3) Pentium, Celeron and Atom will remain.

4) Centrino will also go away and Intel's WiFi and WiMAX products will inherit the name starting in 2010.


Only the Core i7 is allowed to run in a LGA-1366 socket, however there will be LGA-1156 i7, i5 and i3CPUs . The number of memory channels and the presence of a QPI link does not determine branding. In other words, Lynnfield will be both a Core i7 and a Core i5 depending on the SKU.

The LGA-1156 Core i7s will be the 8xx series, while the LGA-1366 i7s will be the 9xx series. The i5s will be the 6xx series and the i3s will be the 5xx series.

Four cores and HT enabled with turbo mode yields you a Core i7 on the desktop. If you only have support for up to 4 threads then you've got a Core i5; take away turbo and you have a Core i3.

In mobile, things are a little different:


The mobile i7 can be 2 or 4 cores and support 4 or 8 threads, which makes sense since there will be more dual-core than quad-core mobile processors. The rest of the lineup follows the desktop rules; i5 and i3 are capped at 4 threads and i3 doesn't have Turbo.

I've got one more thing to report. Remember how I wasn't totally sure about the turbo modes for the top end Lynnfield processor in our preview? I think I've got it:


From what I've heard, this is going to be a Core i7 870 and the turbo modes are similar to what I estimated. With two cores active this thing will turbo up to 3.46GHz (4 speed bins). That's going to be a huge boon to performance in games and other apps that have difficulty using more than 2 threads. Combine that with Windows 7's superior thread handling and I believe we have a winner on our hands

Only the Core i7 is allowed to run in a LGA-1366 socket, however there will be LGA-1156 i7, i5 and i3CPUs

^ that is really what annoys me. there is going to be alot of confusion over the LGA-1156 i7 and the LGA-1366 i7 :freak:




AnandTech: Intel Quietly Announces Core i5 and Core i3 Branding

And now there is i9.....

I won't be upgrading for a while, but I hope AMD is doing good when I decide to upgrade next... I don't like limited upgrade options.

 

[hikaricloud]

This is going to be worse than the 423, 478, and 775 Pentium 4's.

You can already here the sound of me banging my head into the desk can't ya.

 

[hikaricloud]

God, it's a haunting sound mate. You need to stop that before you need to buy a new desk.

 

[overlord20]

So what happens when we need to upgrade our core i7? we need to buy new mobos?

 

[hikaricloud]

I think they're continuing making CPUs for the 1366 socket, but they are going to be more geared towards server stuff.

Could be wrong, though.

 

[tastegw]

i9 will be on the x58 chipset

q1 2010, i9 is 6core/12thread

 

[overlord20]

So we will be able to upgrade from the core i7 to the i9 without a new mobo if that is what im hearing.

that is correct.

but there will some cpu's on other chipsets that will be just as good or better than the i7 in the future aswell.

but i think the spirit of your question is, will x58 chipset have more life in it, and the answer is yes.
