Latitude E-Series Anticipation Thread

If it is just a simple price adjustment, it should be no problem. But if you had to change the configuration to get a deal (like I did) then it is a different story.

 

Wonderful! They had better make this adjustment in Canada as well. I know we never get deals here, but that's one heck of a price reduction. We've gotten it good so far with the Latitudes - the prices are directly derived from the US prices and the exchange rate. That puts the E6400 right back into my budget. Now let's hope that they didn't put a T7250 in this or remove the Wi-Fi card. If they make this adjustment, they have another buyer that instant.

+1, mine's already in the queue but saving a couple hundred bucks is always a welcome thing.

 

A budget CPU would be the easiest way to get the headline price down.

I'm still curious as to where Dell is headed with the E5xxx laptops. The difference in price isn't enough to justify buying it. Especially with only 1 year of warranty and no Wi-Fi.

I just know that Dell has avoided the budget CPU's in their Latitudes so far. All I want is a Pxxxx for the battery life.

Are there any definitive tests comparing the newest T and P series? From what I've read the P series has little benefit, unless you are stressing the CPU a lot since most people are on idle 99% of the time and the idle power consumption between the two are almost the same due to the same process being used to make both CPUs. I don't think the extra cost is worth it, if the T and P processors are the same speed but one is 35W and the other is 25W TDP.

 

They should be the same, if they have the same l2cache, speed and fsb. The only thing I'm not 100% about is if the one with the lighter W value produces less heat. Otherwise they should be exactly the same.

 

They all come from the same silicon but the P series will be those which have slightly lower power requirements in all operation modes.

All is revealed in section 3 of Intel's datasheet 32012001.pdf. For example the T9400 and T9600 can draw up to a maximum 47A at up to 1.25V at full speed, up to 22.4A at up to 0.95V at 800MHz, and up to 10.5A at up to 0.85V in the C4 sleep state. By comparison, the P series have a specified limit of 38A at up to 1.25V at full speed, a maximum 17.5A at up to 0.95V at 800MHz and up to 6.7A at up to 0.85V in the C4 sleep state. So, while the specified voltage ranges are the same, the currents of the P series are lower.

The P8600 in my E6400 seems to have an IDA voltage of 1.20V (the range is 0.9V to 1.3V), 1.1375V at 2.4GHz and 0.925V at 800MHz. RMClock seems to work OK but the CPU crashes at 1.025V @ 2.4GHz. At full load, my core 1 temperature peaked at 66C whereas core 2 reached 73C, which shows a significant difference in the power consumption of the two cores.

But during idle, does the power consumption give a noticeable increase in battery life? While you've said power requirements are lower in all modes, figures are really only compared on load and is not representative of the average users' usage.

 

Thanks for the pictures! Does anyone know when the blue and red will be available? Also, some of you are purchasing with only 1 GB of memory and adding it yourselves. Is it tough to do? I guess just buy from ebay or somewhere? Oh, and has anyone used either of the E series docks yet?
