Core Duo T32xx vs Core 2 Duo T5xxx

I know that Core Duo is older than Core 2 Duo. I assume that the T5xxx is faster and more energy effecient than a T32xx. What I am wondering is are they from the same "family" cuz of the "T"?

Looking at laptops and there is a bit of a price jump between the CD T32xx and the C2D T5xxx. Is it worth a $125+ price difference?

 

They are the same excpet for the L2 cache. The T3200 has 1MB, while the T5800 has 2MB I think. There isn't a big difference between them and not worth $125 in my opinion.

 

The T3200 isn't a Core Duo. It is a Pentium Dual-Core and it is newer than most, if not all processors in the T5xxx range. That being said, the T3200 is indeed a T5800 with just half the cache which is probably not worth the extra $125.

 

Are Pentium Duo Core more energy efficient? How are their performance compared?

 

Well apparently Intel officially calls it a "Pentium Processor for Mobile": http://processorfinder.intel.com/details.aspx?sSpec=SLAVG... but if you look at the Product Documentation link, it even says "pentium_dual-core" in there, so I don't know what Intel wants us to think. It's generally accepted that T3xxx series processors are Pentium Dual-Cores; at the very least I can guarantee you it's not a Core Duo. But I mean at the end of the day, it doesn't really matter what the name is...

 

Thanks I edited my last comment before. Gets kinda confusing with all these different names.

 

Pentium Dual-Cores usually have a Core Duo or Core 2 Duo counterpart with identical clock and FSB speeds, but twice the amount of cache. The T3200, as mentioned, is basically a T5800 with half the cache. In normal day to day use, you won't notice much of a difference. There may be some very small power savings over the T5800 again due to this reduced cache.

 

Actually, the Pentium Dual-Core T3200 is based on the Core 2 Duo T5750 (the T5800's predecessor). Both are 2.0GHz with 667MHz FSB speed, the T3200 just has half the L2 cache (1mb vs. 2mb).

The Pentium Dual-Core T3400 is based on the Core 2 Duo T5850 (the T5900's predecessor). Both are 2.16GHz, 667MHz FSB speed, just the L2 cache is same as above.

All of the T3xxx, T5xxx and T7xxx Intel processors were based on the "Merom" core, which was the original Core 2 Duo design.

These are being phased out by the newer T4xxx Pentium Dual-Core, T6xxx Core 2 Duo and P7xxx/P8xxx/P9xxx/T9xxx Core 2 Duo models. All of which are based on the newer "Penryn" core.

 

i see these questions all the time, and i'll tell you what, i don't know much about processors. but i do know that whether it's T3200 vs. T5800, T5800 vs. P7350, P8600 vs T9400.... they always say it's not worth it. the question is, what is your budget and how much are you willing to spend on your laptop? One step up is always just going to be a little bit faster, but probably not noticeable at all. the truth is, most of the upgrades for purchase are usually ripping you off a little. Check your budget and see what fits. In my opinion, if you're looking for a budget machine, and if you have to ask if it's worth it, then it's probably not worth it.

... for what it's worth, i just received a new dv7t with a P8600, and i had been using a T5800 for the last 2 months.. for the basic functions that i use my laptop for, i cant notice a bit of difference in speed. and that's supposedly $250 worth of upgrade... think about that.

 

It was so much easier when it was just Pentium I, II, II and IV.
I wonder if it is a marketing ploy?

Thanks that helps. My last HP cost $2000 but I found that even though the specs were great on paper...I was kinda disappointed, expecting a bigger difference from my previous computer.

This time I'm going more low to mid-range priced. Over the years my needs for a computer have changed. More a general user and almost no pc gaming. No point spending $150 more just for my browser to load quicker (if it even does).

Battery time is important though. Never AMD again on a laptop though...in the near future anyways.

 

Just to basically reiterate what sublime313 said, I have two laptops- one with a 2.26GHz P8400 (3mb L2 cache memory) and the other (Dell Latitude E6400) with 2.53GHz P9500 (6mb L2 cache memory). Even when I'm multitasking, I can't really tell a difference! I would have been fine with the P8400 in my E6400, but I got it from Dell Outlet and this one had all the stuff I wanted.

I recently ordered a Toshiba Satellite L305 for my niece and it has the 2.16GHz Intel T3400. I was surprised that it didn't feel the least big sluggish in Vista Home Premium (combined with 3GB of RAM, especially).

 

T3x00 = 667mhz fsb 1mb l2 cache
T5x50 = 667mhz fsb 2mb l2 cache
t5x70 = 800mhz fsb 2mb l2 cache
t5800 / t5900 = 800mhz fsb 2mb l2 cache.
