T4300 vs. T6600

Hey all. I'm looking into getting a new laptop and was wondering if there was a significant performances/battery life difference between the two processors. The graphics card is the GT230M so I'm assuming that will bottleneck most games. The use for this laptop is mostly surfing the net, office work, and light/medium gaming. The difference between the two laptops is only $50 but without that I can hit the sweet 800 price point. Thanks.

Edit: I might also consider the p7450 if the performance jump justifies the price increase.

 

Edit: Deleted post.

 

Not being following latest CPU, but I thought the T4 series are the cheap Pentium ones with only 1mb cache2 and without VT (meaning you can't use XP mode in Win 7),where T6 series has 3 and I think the biggest difference between the P series is P series uses less power.

 

I see. I might just opt for the higher processor then.

 

Well, it all depends on your budget and what you use your laptop for, i.e. If you watch video a lot the extra L2 cache is quite important. If you move around a lot then level watts will give you more battery life. All up to you.

 

Avoid the T2xxx, T3xxx, and T4xxx if you can. Go for the T6xxx or even better the P-series for better performance (speed and battery life).

 

Thanks for the input. I think I'll go with the the P series for the battery life and the availibility (I called Frys and it looks like the model with the p7450 will be in stock on Thus rather than ordering online).

 

According to PASSMARK the T6600 performs 21% better than the T4300

I have been trying to compare the T6600 to the P8400 for performance , PASSMARK has the P8400 only beating the T6600 by 1% , which i am very surprised at.

I have been looking for a Wprime 32m benchmark , but the Wprime thread does not have either cpu`s

Does anyone have the difference between the P and T series in terms of battery life and heat? Because if a 1% is the difference between 6600 and 8400, I might opt to save the $50.

 

From Intels info....... http://www.intel.com/products/proces...about/core.htm

"T" = Mobile highly energy efficient processors with TDP 30-39W
"P" = Mobile highly energy efficient processor with TDP 20-29 W



Or example according to K-TRON , how this translates info runtime i do not know.

The T6600 falls in the 35 watt TDP, but it doesnt use 35 watts
the P8600 falls in the 25 watt TDP, but that doesnt mean it uses 25 watts.

I would expect the P8600 to use 23watts or so under load, and the T6600 to use close to 27watts.

Intel is smart with there marketing, processors which do not fall in the less than 25 watt TDP zone get bumped into the 35 watt TDP bracket.
So a 26 watt processor will fall in the 35 watt TDP bracket.

Intel doesnt label the processor as 27Watt, cause than people would see than a 2 watt difference isnt worth the extra money for the P series chips. So they keep a 10 watt difference, which is enough for people to pay more for the P series chip.

In reality, they will use close to the same power, and run the same temperatures. You can thank Intel's Binning methods for this

K-TRON

 

At idle, the power consumption difference is minimal (a fraction of a W, within range of error). Most people never load their CPU to 100% for the full time on battery, so stating maximum power consumption is useless in any sort of practical battery life comparison.

 

Thanks for the good info. Now I'll have to debate between that $50 difference between the 2. Have a few days to think about it.

 

If you compare voltages at idle the T6600 only needs 1.00v when the P8400 needs 1.05v , so on idle the T6600 might use less power than the P8400

EDIT : also if you want to undervolt the P8400 has a 8.5 multiplier , when the T6600 has a 7 , RMClock does not support half multipliers

http://ark.intel.com/Compare.aspx?ids=37255,35569,

 

So I can't undervolt 1/2 multipliers or is it just harder? Because if its the former, I think that clinches the decision for the T6600.

 

You can undervolt half multipliers, it is just harder. You just have to search the forum for the instructions on how to.

 

Thanks for all the input. Barring any super change, I will be going with the p7450. With taxes, shipping etc... its only a 40 dollar difference and my father (who will help finance this deal) prefers the brik n mortar store over getting it off sony.com.

 

good choice to get P7450.. T4300 is a pentium dual core, a very low standard of a dual core whereas T6600 is just average.. P7450 should be great...

 

According to PASSMARK the P7450 has exactly the same score as the T6600 , the only difference is the TDP, which has been said to be mealy a marketing gimmick as the difference in actually power usage is very small, maybe a few extra minutes battery life.

 

t6600 is slower and has less L2 cache... can you ppl plz stop quoting passmark?

 

The OP already purchased his CPU... /thread

 

Actually I can't purchase it until tomorrow but that's mostly an issue of semantics.

 

The Wprime for the P7450 and the T6600 is the same as well, so stop yourself!

 

As I mentioned, the preconfigured in store model comes with the 7450. Should they somehow fail to have that model and I order online, the t6600 is what I would order.

 

would i be able to take my T4300 and replace it with the P7450?

Hey i want to buy new laptop for working purpose(coding and developement,photoshop,flash) and little bit for gaming and video.I have two options in my budget.

1.sony viao nw20ef(Processor:t4300)
2.Toshiba L500-1cq(Processor:t6600)

I am mainly concern about L2 cache memory.Because t4300 has 1mb while t6600 is having 2mb.so ,does an extra 1 mb cache memory is important for me with consideration of my purpose.
reply soon.I am in hurry.
Thanks in advance.

 

u can easliy upgrade the processor later on but buy the one with the T6600... it has a better chipset , which means u can upgrade to more CPU's... anyways what will u be using the laptops for? If it's for gaming , buy a different one... both of these are only good for general internet surfing and watching movies...
