    Speed difference 5140 and 6230

    Hi,

    my app that runs extremely fast on a Nokia 6230 (as opposed to older series 40 phones such as 6610/7210) and I think I can add some more effects in order to use all the CPU power available.

    But does the 5140 (and other series 40 v2.0 devices) have the same CPU power as the 6230? I am asking since the 6230 has an mp3 player and other features that might require a faster CPU.

    So is it reasonable to take the 6230 as a speed reference for all new Series 40 v2 phones or is it faster?


    Any other notable difference between these phones (except that 5140 doesn't support bluetooth, sigh).?

    Thanks,
    Jacques

    I dont have full info about 5140 but it's slowly than 6230
    Besides this as I know different devices Series 40 2.0 will use different chips as it was in Series 40 1.0 devices

    Jbenchmark

    According to Jbenchmark the 6230 would be twice as fast as the 6600. That's why I have some doubts about the trustability of this benchmark.

    If it's true then the 6230 is really even faster than I thought.

    It would be so nice if there was a documentation stating what hardware was inside each phone. Nokia?

    The 6230 are not twice as fast as the 6600. The two handsets might be comparable in speed, but I actually expect that in general you will see the 6230 to be a bit slower than the 6600.

    I am sure that S40 handsets with MIDP2.0 will have very different speed performance. A phone like the 3220 I would expect to be a lot slower than the 6230.

    I don't know about processor speed, but when comparing the 6230 to the older Series 40 phones you have to take into account that the 6230 has two times more heap memory available. If your application is pushing the memory limits on older Series 40 phones (which isn't saying much), then the garbage collecting might make the application run a lot slower.

    seconding blackjack75 wish:

    it would be really helpful to have a list of processor + java vm for each device!

    meanwhile, this is extremely hard to find such info (as if it were a strategic decision by manufacturers to keep things blurry in that area...)

    btw, knowing only about the processor is not enough, e.g.

    a 3100 have an ARM-9 at 52mhz while a 6600 have an ARM-9 at 104mhz, but...

    the 6600's java vm is CLDC-HI (aka Monty), which is a Just In Time compiler (bytecode is compiled to assembler on the fly) making java running, grossly said 3 times faster.

    so... a 6600 is at least 6 times faster than a 3100 on "number-crunshing" (i own both of theses devices, so all this is not only theoretical :-)

    btw, i think jbenchmark is flawed because it does not consider pure-processing power.

    concerning graphics performance, it's another story, since "moving images" is done natively and don't rely on java (in that field, jbenchmark is providing helpful info...)

    so yes, really wondering what beast is inside the 6230 & co!

    a few (silly) bets:

    6230: ARM-9/104 with CLDC-HI
    5140 & 3220: ARM-9/52 with CLDC-HI

    3100

    Hm, the 3100 is a midp 1 phone. Would that mean the 7210 and 6610 already had the same speed? It seems unlikely.

    Any idea what the processor inside a 7210 / 6610 / 6100 is?

    5140 should be good benchmark for other Series 40 v2.0 devices

    There are performance differences among the Nokia devices due to the differences in the underlying hardware platform, which are not always logical, i.e. so that newer device would always have at least as much processing power as the previous devices. This can be for example due to different customer segmentation or different price point. This comes clearly visible when 6230, first Series 40 Developer Platform 2.0 device, has better performance than 5140. Therefore, 5140 is in fact better as the performance benchmark for other Series 40 Developer Platform 2.0 devices than 6230. As far as I know, all the coming Series 40 Developer Platform 2.0 compliant devices should have at least as good performance as 5140.

    can't tell much about 7210 and the likes... personally i'm focused on the "new" generation...

    for those interested, the following link:
    http://my-symbian.com/7650/techdata.php
    is providing (almost complete) specs for the new nokia symbian based models, such as 6630, 6260 & 7610.

    in short, it looks like they're still based on the ARM-9 technology, but at ~123mhz instead of 104 (compared to the 6600 generation).

    hey, it looks like nokia and sony-ericsson are on par this time (according to some quick homemade tests on a 6600 and a K700: the later is about 25/33% faster...)

    what those specs don't tell however is which java vm is used but it's well known that symbian os (starting from version 7: i.e. 6600) java is based on the fast CLCD-HI vm.

    okay, back to work before getting a geekiness-overdose :-)

    CPU speed of 6230

    Hey,

    has anyone figured out how many Mhz the CPU of the 6230 actually has?

    6230 vs 6600

    Well we have both a 6230 and a 6600 here. I'll bet they have the same or an equivalent CPU. The 6230 runs at least at fast when processing data as the 6600. For thos who don't know the 6230 has a mp3 player that can play 320kbits mp3, and therefore has a decent CPU.
