    Can someone explain to me please how/if the Omap 1ghz is faster or better than the Sdragon 1ghz?...I thought i saw somewhere about the size in nm of the chip or something like that. I just want to be educated so when i tell someone my DroidX is faster than their Dinc i can tell them why. .....if that is the case. Thanks in advance.

    There's tons of results on youtube and such. But yes one thing is that the omap is 45nm so it uses less power and creates less heat than the snapdragon. I don't think that is necessarily what makes it faster though.

    omap + gpu is more efficient than snapdragon + gpu. performance is also much better on the omap setup. hmmmmm, for every minute of use...the omap can output double the performance of the snapdragon, while utilizing a little less power than the snapdragon.

    battery profile management gives you over around 8.5 hours of use

    screen is bigger, with multitouch.

    magnificent call quality due to antennae and the noice cancellation setup.

    It runs on the BEST NETWORK.(but youre both on it)

    8gigs internal storage, 16 gigs expandable @ stock ( 32gig expansion slot limit)

    camera with dual led.

    Great build.

    i would bring those up..

    ..yeah i kind of already know most of the specs. But a lot of people (non techies) will just say well they both have 1ghz's so their the same speed. ..i on the other hand am a dork and i know that is not the case but i need some info to back it up...for now i'll just go with the 45nm design and dedicated gpu make it more efficient and efficient=speed in some cases.

    i don't think the gpu is dedicated.

    well theyre both great processors. the omap setup is just better tuned and uses a smaller fabrication process which makes it even better as far as heat and battery draw are concerned. Overall the omap is just better in every way possible. i point at bad coding...but that is really not my field, so i could be wrong.the only thing the snapdragon is good for, is to kill the battery very quickly.

    i found this for you:

    TI Omap is based on the arm-cortex A8 tech which is supposedly to be more efficient and fast. Qualcomm has a long history of bad graphics support. The GPU is horrible. Well, its not exactly that bad but the drivers that are provided for the use for Qualcomm's GPU is often inadequate and hence underperforming. Sure the snapdragon is a whole lot better than the previous qualcomm SOCs (i.e. msm72xx series). But I feel that the reason for it is due to the higher clockspeed. The 1ghz speed tends to help with the peformance. But for me personally i would prefer the TI OMAP simply because it is a cortexA8 core which is better performing and the much better GPU.

    So in a nutshell,
    Qualcomm Snapdragon clockspeed maybe higher than the OMAP but the performance wise is comparatively close.
    BUT however the OMAP GPU is better than Snapdragon.
    With the ongoing increasingly graphically intensive trend, i think the way to go is with TI's OMAP. (Or untill qualcomm releases the 1.5ghz dual core snapdragon, then i would consider it

    Why would you need/want to make any kind of comparison between your phone and theirs? It's just a phone, and would make you sound like a bore. Find something else to talk about!

    so technically, when the snapdragon 1.5s come out...dont get them. they are basically poorly designed chips that run even faster and more inefficiently than the current snapdragon ones.....Or at least that is what i gather. another possibility is being able to overclock the x to 1.3 ghz and it performing on par with the 1.5 ghz snapdragons....

    some people like to talk about technology, others about politics, some about sushi... many love to talk about sex and happyness, success and money, etc.

    depends who youre with really. how do you know his friend DOESNT ENJoy a discussion backed up by facts?

    EXACTLY!!! i'm not just going to walk up to some joe sixpack that i see using a Dinc and say hey "my phone is faster than yours".....i'm not that much of a ****. But when i have my DroidX in my hand and friend of mine walks up saying his phone is the same as mine cause his ALSO has a 1ghz chip i can say well just because their both 1ghz doesn't make them the same......

    also...in case you haven't noticed SushiFiend ....phone/comparisons happens to be a pretty hot topic in these forums. ...i'll take a crunchy shrimp roll, volcano roll, spicy tuna roll please. with low sodium soy. Thx

    Snapdragon sounds "cooler" than OMAP, so take THAT! ;)

    You folks do know you will be on the low end of tech totem pole in a few months too, don't you? Dual cores are coming- marketing departments next buzz words ;)

    the GPU on the omap is faster than the snap dragons GPU. which gives it a slight performance increase all around therefore making it THAT much faster.

    and you do know that the people that buy the dual cores will be on the low end a few months after they get theirs, don't you? ..... i realize my phone will only be the latest and greatest for a few months...but if you keep waiting for the latest and greatest you will probably go without. I'm fine with it , it is the way this hobby is. Nothing you can do about it.

    OMAP is better, period.

    First of all, having 45nm does not make it any faster by itself. If you studied how semiconductors work, the die size has no DIRECT correlation with the speed, But gives POTENTIAL to be clocked faster.
    However, the main reason that the experts theorized for the faster speed is the use of LPDDR2 memory vs LPDDR1 in Snapdragon and OMAP 3430. (GPU is clocked higher in Droid X vs the original droid)
    Ruminations on various benchmarks for the OMAP 3600s, Hummingbird, and Snapdragon | AlienBabelTech <-- interesting read
    The article also talks about how even though hummingbird/A4 in iphone/galaxy uses SGX540 gpu, due to LPDDR1 memory in those chips prevent them from fully using its potential (this is their educated guess).

    now that is good info...i forgot i had saw that somewhere about the diff type of memory as well.

    The internal design architecture can make a significant difference in performance. Processor speed is only one factor. More critical is how many cycles it takes to perform a task.

    Well, there is a bit more to say. First. the X uses the 3630, _not_ the 3640. Yes, the 3640 is listed as the only 1 GHz model, but it's been confirmed a number of times that the X uses a 1 GHz version of the 3630. This, we're told, is good because the 3630 is better at managing memory than the 3640. Also, like this article states, the X uses LPDDR2 ram and not LPDDR1 like all previous phones (the iPhone 4 _might_ have LPDDR2). LPDDR2 has twice the bandwidth of, and consumes 1/3 less power than LPDDR1. This means better performance at lower energy costs. The same is true when comparing the OMAP to the Snapdragon. The Snapdragon is a 65nm architecture while the OMAP is uses 45nm, which means that the OMAP can achieve at least a similar performance whilst using less energy. It also means that the OMAP has more headroom for overclocking, though that point may be moot on the X anyway.

    Lastly, the OMAP is packaged with the PowerVR SGX530 GPU which runs at 430MHz, while the Snapdragon comes with the Adreno 200. I haven't been able to track down much info on the Adreno, but I do know that it sucks. The PoweVR is far superior. I'm uncertain about the difference in power consumption and the performance difference specifics, though.

    on which one? I thought the X had a dedicated GPU

    And its not surprising that the X and the new Samsung phones use LPDDR2 memory.
    (According to this the Galaxy S uses LPDDR2 too...and I thought the iPhone 4 used the 535, and just the Samsung phones used the 540...)

    But I also got this from an article back in June:

    Inside the Motorola Droid X | Nanotech - The Circuits Blog - CNET News

    That could explain the difference on the Quadrant benchmarks vs. the Galaxy S.

    I thought A4 and hummingbird were nearly identical but guess not.
    The quadrant might have something to do with Droid X not really using Motoblur and Samsung's touchwiz just being inefficient?

    I mean, I would call them nearly identical too....lol Some ppl dont. They more related than the other chips out to me. And I thought about that too with TouchWiz.

    U aint the only one. Try this too: AMD Z430.

    The Snapdragon is hard to find detailed info on too for me. Its a user here EarlyMon that has some useful info about the Snapdragon. I'll look for that post in a minute. With the OMAP info out there, u could damn near build your own chip...lol
