I noticed that E71 has faster CPU clock than E90, does that mean E71 is going to be faster than E90?

Nokia E71: CPU Clock Rate: 369 MHz
Nokia E90: CPU Clock Rate: 332 MHz

What gives? I paid so much for e90 only to find out the processing power is less than e71

E71 released about 1 year after E90 is launched. Of course there would be some advancement in technology features. It is inevitable, since technology is developing continuously. Mind you, they are electronics - not some kind of jewellery which generally holds its initial value.

I think nokia is clever enough to segmented e71 from its older brother e90. Even though e71 have better processor, you will still get higher res screen, bigger keypad and better camera in E90.

I think the one who can replace e90 from its throne is its successor, even though some other models or other segmentation have new features over time. Eventually there will be a new communicator successor who get the all bell and whistles for "the time its launched".

Try to compare e90 from e61i. You get better suited comparison there, in this perspective.

The Freescale processor in the E71 has different architecture than the OMAP2420 processor in the E90. It doesn't make much sense to compare just the clock speed of two different processors.

It's like with Intel and AMD processors. Even tough they're both based on the x86 technology and are compatible (just like the E71 CPU and the E90 CPU are both based on ARM11 technology and are compatible), differences in their internal architecture cause that e.g. some AMD processors are faster than their Intel equivalents at LOWER clock speeds.

There is also one important additional difference between these CPUs: the Freescale in the E71 is a single-core CPU whereas the OMAP in the E90 is a dual-core CPU. The E90 processor has separate core to handle the baseband (telephony and network related tasks) and separate core for applications. The E71 processor has only one core, dealing with both network and the OS. So while (thanks to its faster clock) it can sometimes be faster (e.g. when there is no network/telephony activity to handle), with such activity in the background it may actually turn out to be slower. And it's worth noting that some network/telephony activity happens almost all the time, even if you're not connected to the Internet or making a call at that moment. The phone constantly updates its location, switches between neighbouring base stations, monitors their signal quality, checks which services are available (GPRS, 3G, supported call encryption algorithms, etc). It only doesn't do any such operations in Offline mode.

Last but not least, the OMAP in the E90 has graphic and video hardware accelerator, missing from the Freescale. That's why you can e.g. run the full OpenGL ES version of Quake on the E90 but not on the E71. That's also probably why the E90 can record high quality VGA/30 fps video while the E71 only records QVGA clips at some poor 10-15 fps.

Long story short, the OMAP2420 is definitely more powerful than the Freescale in the E71, so don't worry, you didn't waste your money.

The Freescale processor of the E71 is as old as E90's OMAP. E71 is not the first phone using it, it can be found in many older models starting from the N76 which was announced in January 2007, BEFORE the E90 was announced (in Feb 2007). It's not newer and, as I wrote, it's not more powerful and definitely not more advanced when it comes to technology and architecture.

Even though e71 have better processor

It's like saying that single-core Pentium clocked at 3 GHz is better than Core2 Duo running at 2,4 GHz... It's simply not true. As I said, CPU clock alone means *nothing*.

Thanks a lot for your information. Although I have both devices, it worries me a bit when I found out that the processor clock speed on e90 turns out to be lower.

but your information is very helpful, and thanks again

Anyway,

I just bought JoikuSoft Premium from this site for my E90, will this work for my E71 as well?

Of course, it is compatible with both the E90 and the E71. But I don't know what kind of registration method (preventing illegal use) this software has. If it has a registration key that's based on the phone's IMEI then you won't be able to run it on another phone without obtaining a new registration key for the new IMEI from the developer.

If it's just a full version that doesn't require registration (or the code is not IMEI based) then you'll be able to install it on the new E71, but to stay legal you should uninstall it first from the E90 as you only bought one licence.

To get concrete and reliable information you'll have to read the licence agreement of the program or contact the developer (author of the software). Developer's customer support contact email address can be found in the message you got from the shop after placing your order. Each developer has different policy when it comes to providing new registration keys for upgrade phones.

No worry,

I only have 1 sim card, I use one phone at a time. I haven't installed it on e71, but I just wonder in case I want to transfer it later on.

thanks again for your info.

As I wrote, it all depends on whether the program's registration is IMEI based or not. If not then it'll install and run just fine.

[AvantGarde]

I don't think it can be installed on the E71 because it requires me to send the code to the server to prevent illegal copies

well .. then e71 is not getting the joikuspot premium.

[Michal Jerz]

Try to contact the developer and tell them that you have two phones which you use interchangeably. Maybe they have some fair policy for such users and they'll offer you another code for some small amount, or maybe for free.... You already bought one copy, which is not so unimportant for a developer in this world filled with people using warez. It's always worth trying...

[AvantGarde]

Thanks for your advice, I'll try it and I hope they are kind enough to let me install on my other phone.

another thing, is that even though they are both on the s60v3, this e71 is way more stable and smoother running then my e90.


maybe michal or bentl have some kind of explaination for us to understand?


certiainly there is an upgradable difference in the s60v3 software between them, just dont know enough about how different the coding would need to be for communicator over the e71?~!

[jcompagner]

i hope we get another firmware upgrade soon that also gives us the software updates the e71 has. For example the look up in the contact book when you start typing when you are on the desk/standby screen.

Also the E90 does not support phone book acces for bluetooth handfree headsets, but E71 does. So I cannot use BH-902 with E90 to display the caller ID from the phone address book
