Core Duo T2700 (Yonah) vs Core2 Duo T7600 (Merom)

[Red_Machine]

I'm looking at getting a laptop that shipped with a Core Duo CPU, but it capable of taking a Merom core Core2 CPU. Both CPUs have the same core clock speed and FSB speed, however the Core2 is obviously 64-bit and also has double the L2 cache and SSSE3. I've looked at comparisons for both CPUs, and it really seems like there's barely anything between them performance-wise. Even in benchmarks, the Core2 is barely ahead of the Yonah, and Geekbench even rates the Yonah as faster. So I'm honestly kinda confused as to what I should buy. I suppose that given the difference in performance is so small, I should go for the Yonah to ensure maximum compatibility and to avoid any voltage issues. What do you guys think?

I would go for the laptop with Core™2 Duo Processor T7600 since it is 64 bit

This isn't me trying to choose between two different laptops, this is me trying to decide what CPU to buy upgrade an existing laptop.

Ok, then still I would go for the 64 bit Core 2 Duo Processor T7600, unless you can find something better ofcourse.

the difference will depend on how much cash you have allocated, The Yonah will most likely be the cheaper option for the cpu upgrade.
How much RAM does the machine have? Keep in mind 32 bit operating systems can only address up to 4Gb of ram.

 

[Red_Machine]

The chpiset is limited to 2GB according to Dell, but various forum posts I've found have said that 4GB has been installed successfully.

What laptop is it? Some laptops are very touchy about CPU's.

I'd go for whatever is cheaper, but the T7600 is probably easier to find.

 

[cdawall]

Why is this a question the T7600 performs better use it. [/thread]

Some laptops are very touchy about CPU's.

Some will not even let you change CPUs. Some use surface mount technologies and for sure, power and cooling are configured for the CPU the notebook came with. While admittedly very close, these processors have different voltage ranges, different power consumption and different thermal properties. In a PC, no big deal. In a notebook where cooling is always an issue, it could be.

My advice is to buy the notebook that has everything you want already in it. Worry less about the CPU and go for the best graphics and most RAM. And consider a notebook with a SSD instead of a hard drive.

And remember, if notebooks were intended and designed to be upgraded by consumers, there would be an ATX-like form factor standard for notebooks and a thriving notebook parts industry, just as there is for PCs.

I have had 4 different CPU's in my netbook. The series of laptop he is talking about (C2D) are all easily upgraded and area socketed CPU.

 

[Bill_Bright]

Netbook, or notebook? I cannot say I have ever seen a netbook that didn't have an embedded CPU. Not saying there aren't some out there, just that all the "netbooks" I have personally seen, and many notebooks use embedded processors to cut costs, and to make the computers thinner and lighter.

The series of laptop he is talking about (C2D)

Where did he state he was talking about C2D series?

Depends on the price. If you can find a Haswell Celeron for the same, than not even worth investing in such and old limited platform. I really love old machines, but as a laptop it is simply not worth it, unless you want to run linux, or have issues with hardware acceleration in browsers, supposing the GPU is some 950-3100 Intel or some old ATi/nVidia. And that 2GB ram limit starts to be really nasty nowadays, even though some Win8 tablets shipped with 1GB. If you cannot afford getting something better, dont waste money on the upgrade

In the thread title?

Netbook, Gateway LT3103u. Nothing soldered, now has 4GB of ram, SSD and a dual core cpu.

Right about there. I was nice enough to box the area specifically so you didn't miss it.

If your laptop can take a T7600 then why not have a look for a T7600G. The G series has an unlocked multiplier so you can overclock one to the moon. Here is a screenshot at 3823 MHz. This is in a totally different league compared to the regular T7600 or to the T2700.

Nice one, never knew those, I think they are hard to find though.

Okay, I didn't catch that CD2 means Core 2 Duo. My bad. But the point I did a poor job of making is that being C2D in no way suggests, implies, or infers every Core 2 Duo processor is socketed on every motherboard ever made. There are many that are not.

Embedded Core 2 Duo

Nor does it imply all makers of all notebooks/netbooks using any given socketed processor provides an upgrade path in that specific notebook/netbook. You may have been able to upgrade your processor 4 times in your specific netbook, that does not mean all netbooks - even with socketed processors can be upgraded. And again, this is because there is no industry standard so notebooks and netbooks tend to be very proprietary.

Regardless, my advice still stands - when it comes to notebooks and netbooks, buy the computer that comes with what you want and worry more about the RAM and graphics, and consider a SSD.

 

[cdawall]

So how is he upgrading the graphics? Majority of C2D (which has always meant core 2 duo since like ever...same way AXP is athlon XP) are socketed in notebooks, this is from personal experience, it appears the OP has already looked up compatibility and knows the CPU will work so why on Earth are you arguing anything about his upgrade path. He asked a very very simple question. Which is better? The T7600 is the answer.

 

[Red_Machine]

I wasn't asking which was better, I was asking it it was worth getting the T7600 considering that there is so little difference between them. The laptop was designed for a Core Duo, so I thought perhaps it was a safer idea to stick with the Yonah core instead of opting for the Merom.

If it supports the Merom install the Merom. There were quite a few tweaks done in between CD and C2D clock for clock performance was improved.

I never said anything about "upgrading" the graphics. I said buy the computer that has what you need, and worry more about RAM and graphics than differences in CPU performance.

There is actually quite a bit of difference. The T7600 supports 64-bit operating systems. This is big, IMO as it means you can have more than 4GB of RAM (or use the full 4GB if only 4GB installed).

And the 7600 has twice as much cache which significantly improves performance (though greater RAM support is more significant).

But only you can decide if that is important. If you will be running off battery much of the time and longer run times are important, then perhaps the 2700 is the better option for you.

Hey, you brought up "upgrading" graphics, not me.

And again, this is because there is no industry standard so notebooks and netbooks tend to be very proprietary.

There is no such thing as a "proprietary" socketed CPU. They are ALL industry standard. The only roadblock you might run into upgrading a CPU in a laptop is with the BIOS not supporting it.. But that's what bios-mods.com is for...
