The Ultimate CPU Guide

It will slot right inbetween the 2.0GHz and the 2.2GHz TurionX2's.

 

You really can't call it the ultimate CPU guide if you don't cover everyones CPU's. I.e. my X6800 is not listed

 

Hey,
I'm planning on getting this laptop: http://1toppc.com/Merchant2/merchant.mv?Screen=PROD&Product_Code=C90S&Store_Code=GPS

The processor I chose is not listed on your chart, Intel Core 2 Duo Conroe E4400 2.0 GHz 800FSB 2M, and after doing further research I'm hearing it's a desktop processor? Am I cooked?

 

Out of curiosity I just did a search for "E4400" on newegg.com and came up with a curious result. Some barebones came up but nothing that included a laptop, although a couple were desktops with a very small case. I conclude that the processor gives off little heat, but that other processors are preferred for use in laptops.
That's just my take of it. I'm no expert on laptops.

 

Added the TL-62. The reason it wasn't in there is because it's a new processor.

If that's a Core 2 Extreme, it's a desktop processor.

That's also a desktop processor.

I'm going to overhaul this guide soon. Right now there are some confusing things on there, and I'll try to include more processors.

 

Thanks, Lithus for creating this and pointing it out to me. Very useful.

 

I finally found enough time to overhaul the guide. There are quite a few changes and additions. As always, I do appreciate questions, comments, or corrections. Thanks.

 

I have a T5450 which is a P processor on a 667 bus. Since notebooks normally have minimal BIOS setting options, do I need to replace it with a processor designed for only the same bus speed? I don't see a lot of faster processors that run at 667 MHz.

 

No, you can use almost all the Socket P ones on there. I would stick with the T7800 or under or maximum compatibility.

 

Lithus,
Any reason why TL-62 is above TL-60.

>>Turion 64 X2 TL-58 - 1.9 GHz, 2x512 Kb, 800 MHz, S1
>>Turion 64 X2 TL-62 : 2.1 GHz, 2x512 Kb, 800 MHz, S1
>>Turion 64 X2 TL-60 - 2.0 GHz, 2x512 Kb, 800 MHz, S1

 

Because the list is large and my eyes aren't that good.

Thanks. Corrected.

 

Lithus, you can add the Intel Core 2 Extreme X9000 at the top, it's the fastest mobile CPU. I just tested a laptop with it, you can see wPrime results and a CPUZ screenshot here:

They come out too fast.

I do the Intel monthly program, and I didn't know they had that.

 

Anybody knows a way to scale up or overclock the Intel A110 processor for UMPCs??

 

Mobile processors usually cannot be overclocked.

Updated with Montevina.

 

Thanks, exactly the help I was looking for!

 

Any chance of including the small size forms (SP, SL, and SU)? Or are you waiting to see if they become mainstream?

Looks good as always. Great job keeping ahead of the game.

 

Montevina is a platform, not a CPU (which you wrote). When Montevina is released, it will still use Penryn CPU's, the same way Santa Rosa still used Merom CPU's.

 

I'll see. If I do that, then it means that I should put in the current LV and ULV processors, which would add a bunch of work, and then there's the problem of where to put them performance wise, since it's not fair to compare them to full powered processors, etc.

I made sure to mention it as a platform. I don't believe I wrote "Montevina CPU". From the text:

 

I know. I just thought that you could write that Montevina uses Penryn CPU's. Make it clear for those who are confused by all the terms.

 

I don't see T5600

Or is it mah eyes?

 

There's too freaking many of them.

 

You made the monster! Ha Ha!

 

Soon you'll need to include the CPU in the Macbook Air .

 

Aren't those just the low voltage Core 2 Duos? The L7500 and L7700.

 

Montevina processors will be a new socket, B.

 

Thanks for the insight, Lithus.
I'm currently configuring a Dell Vostro 1400 with 2 GB RAM, the nVidia GeForce 8400M GS, XP Professional, and trying to decide between the Core 2 Duo T5270 (1.4 GHz) and T5470 (1.6 GHz). I notice the T5270 is on your list of budget processors, while the T5470 is mainstream. Is there a difference in these processors other than clock speed, or is this just a case of one being at the top end of budget and the other being at the bottom end of mainstream?
I plan on using the computer for mostly web and text editing, with some 3-d modeling on occasion.

 

You can really just connect all of the categories into a big blob of everything. I just had to cut them somewhere for organization purposes.

I would go with the T5470. While it's not going to be a drastic improvement, it usually doesn't cost much to upgrade to that processor, and the clockspeed boost will help with everyday tasks.

 

I can't decide between a lenovo z61m with the dual core processor or the Hp 2718us with the AMD 64 X2 processor (2.1 Ghz). I like the lenovo b/c it's built like a tank but HP has better specs. Which would you opt for?

 

Lithus,

First I would like to thank you for putting in so much work and breaking down each processor group for everyone. I do have one question for you. How often do you update the list(s)? I don't know if you addressed that at the very beginning. Pardon me if you did and I just missed it.

 

It's updated as often as necessary. Whenever something new comes out, I try to get it on the list.

 

If the Montevinas are Socket Bs and Ps, would that mean that they would downclock to the 800 FSBs of the PM965's chipset?

I have no clue, I'm just wondering.

 

No. Montevina IS a chipset. Montevina replaces the GM/PM965, and the Penryn processors that it uses are Socket B/P.

 

Ah, I see. Wasn't paying attention. Thanks! That makes a lot more sense now. That clears up a lot of stuff. All that talk about Montevina processors threw me off.

 

Montevina is a platform not a chipset, it is the fifth-generation Centrino platform. It uses the Mobile 45 Express chipset (code-named Cantiga; GM45, GM47 or PM45).

 

Thank you.

 

Got a new one for you that cropped up on HP's site with the C700T, the Pentium Dual Core T2390, 1.86GHz, 1MB L2, 533MHz, Socket P..........

 

One of the worst things intel has done is release all this special cpu's for IEM alone. Most of the cpus currently in T2xxx and T5xxx fall in that segment. I dunno how cheap they are compared to say T8100( @ $209 tray price) but this just confusing the uninformed buyers.

 

amazing. why not sticky it!?

 

It is included in the Hardware General Info sticky...........

 

Added, thanks. This guide is becoming "The Ultimate Intel Guide w/ AMD strewn about". What's next? The T2345.67?

 

You created the beast. Ha ha, well done, I do feel your pain. It will only get harder and more confusing in July.

 

"Core 2 Duo P9500 - 2.53 GHz, 6 Mb, 1066 MHz, P
Core 2 Duo T9400 - 2.53 GHz, 6 Mb, 1066 MHz, P"

Is that correct? Why is there a model number difference but no actual performance or L2 cache gain?

EDIT: Never mind, I didn't read the "P" PREfix part of your post properly, props on a great little guide

 

Another one from an HP dv6700t:

T5550, 1.83GHz, 2MB L2, 667MHz, Socket P

 

Thanks. Added.

 

Two more from the Compaq 6720s (business model):

T5870, 2.0GHz, 2MB L2, 800MHz, Socket P
T5670, 1.8GHz, 2MB L2, 800MHz, Socket P

Definitely getting confusing. What the heck is the difference between a T7250 & T5870 now?? Or a T7100 & T5670?? It looks like the same gen Memrons with different numbers...........lol

 

I'm just putting them in sequential, numerical order and hoping that Intel has some sense of sanity. I mean seriously, WTF?

Edit: Apparently Intel doesn't have any sanity, given that there's also a T5850 at 2.17 GHz. And now the chart's officially all messed up. Thanks Intel.

Good thing though, there's probably less than +/-5% performance between those various processors so none of it really matters. A cookie goes out to anyone who wants to bench those.

 

Geez, that's one helluva guide!

Oh, but you forgot... LOL

 

Did the original T5xxx series have limitations over the T7xxx units, such as crippled power states/properties? If so, maybe it carries over to these newer 5-series cpus? I'm probably grasping here.....

 

The original 5's were differentiated mostly by the L2 cache, and the very low-end ones, like the T5200 didn't support virtualization. I can't remember anything else significant being different.

Edit: Intel officially sucks. Look here: http://processorfinder.intel.com/List.aspx?ProcFam=2643&sSpec=&OrdCode=

First off, it doesn't have the newer ones listed, but that's to be expected. Neither Intel nor AMD lists just-released processors on their sites for some reason. However, there's freaking a million models! The T5500 is listed at least 4 times, each with a different Spec#, and each with slightly different specifications (whether it supports virtualization, it's steppings, etc). This makes it impossible for even us, techies, to keep track.

So this is what I'll do. In the name of keeping the guide to its original intent (as a simple "what's better" guide), I'll see what I can find for benchmarks (doubt I'll find much if anything) and try to keep it as clean and informative as possible.
