    Thanks for the review, but could the reviewers comment on the temperature differences between the two processors? I'm assuming lower voltage will result in less heat, but it would be nice to see some numbers. Reply

    It's a shame about that DAT not really being useful. It seems like their ideas were hampered by the fact that applications always bounce from 1 core to another. Looks/sounds like a good idea though. Reply

    Thanks for an interesting article, Penryn it seems like a nice, although not essential refresh.

    I'd like to nitpick the SSE4 performance numbers. You state that in case of Virtualdub "Penryn would offer a greater than 40% increase in performance". I find this to be incorrect.

    Let performance or speed (v) be defined as v = work unit / time. v1 is the speed of Merom and v2 is the speed of Penryn. Comparing Penryn to Merom = v2/v1 => t1/t2. Using your numbers 47.3s / 28.2s = 1.677 => 68% better performance.

    It would be correct to state that using Penryn takes about 40% less time to do the job, but that is not what the article states.

    Could I just swap chips out? Reply

    Yup, the D630 uses the 965 chipset (Santa Rosa). But you'd better wait for a BIOS update from Dell first before you think about putting a Penryn in there - I'd expect those to roll out almost any day now, but by Feb. for sure. Reply

    Have I understood it correctly, that you are comparing the SSE4 version of DivX on Penryn with the same SSE4 version of DivX on Merom? Shouldn't you be comparing the SSE4 version of DivX on Penryn to the SSE3 version of DivX on Merom? Reply

    Electric surges drain battery faster. When a device bulb, motor etc starts a peak is occured in load and then load comes to a lesser and steady value. Intel Dynamic Acceleration may result in same for battery. Reply

    how about the Deep Power Down (C6) stage that penryn brings ? Any test on this feature? Reply

    Good review, but just to note.

    Merom (part of santa rosa) supports Intel Dynamic Acceleration, (although T7xxx series only) and since you guys weren't aware of that, the cinebench benchmark (and other benchmarks) with the T7800 might have a skewed score.

    Nice to see that the t9xxx series will step up the performance again and battery life. Altough we can already say that Intel dominated this part of the mobile market for a long time with t7xxx it is now sure that it will increase that even more.

    what i really want to no is what about low end and midstream, how good are these t2xxx - t5xxx - t7xxx series compared to each other and what happens when you put a rather cheap turion class next to those t2 and t5 series.

    @anand i think you would hit a readers max out of such a review, but then again it would take a lot of time and effort to get a nice compare with equal hardware parts and price....

    Looking for cheap 45nm desktop CPUs.

    I was going to build Intel for my latest customer, but at current prices of the 2.1ghz X2 vs. 1.6ghz Pentiums, AMD won again for being at least $35 cheaper.

    It's interesting to see what intel does, but I'll stick with my turion laptop from 2k5. Reply

    I think Intel has moved Cantiga forward a bit from Feb/March to 2nd quarter, but not too far for me to think now is the time to upgrade only the CPU and retain the current Santa Rosa chipset.

    I am happy with my current battery life, but think a huge improvement will come in another quarter when Cantiga / Penryn / and a few other improvements like LED backlit screens, become more available and rolled together. With the chipset change, I am hoping for a much more significant change when largely idle (such as editing) along with the other benefits Cantiga should bring.

    My thoughts would be to hold off, but am interested in other opinions on what Cantiga will bring to overall battery life.

    These new mobile penryn's seem like the ideal candidates for an ultra-low power HTPC that still has enough power to handle the tough encoding jobs.

    Does anyone know if any of the motherboard vendors are planning on releasing desktop boards for these new chips?

    I think AOpen will release a motherboard that will use this penryn mobile processor. They currently have desktop motherboards that takes mobile cpu. Reply

    I hate to be "That Guy" but I'm pretty sure you mean "Battery Life" not "Battery Live."

    Unless it's a description of the PR walloping that Microsoft is taking over the Xbox Live outage. ;)

    Thanks for the catch. The Title is corrected, but it wil not update until the next refresh, so please be patient for a few minutes. Reply

    Just a heads-up, charts on page 4 are borked. ;) Reply
