We know that E71 has faster CPU clock than E90. Nokia E71 has CPU Clock Rate at 369 MHz, while Nokia E90 CPU Clock Rate at only 332 MHz. Does that mean E71 is going to be faster than E90?
Michal Jerz over my-symbian forum has great great answer for this question:
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.

Nokia E90 or Nokia E71??

Well, I have an E90 more than a year now. But I cannot say that the speed on the E90 is something impressive. Especially switching between the inner and outer screen takes some time.
So as far as I can tell, the E90 is quite slow. Probably also the software is some kind of bottle neck.
I also read an article over a year ago, where the display performance was tested. The inner and outer screen seem to run over the same bus and the same chip is processing the stuff. Therefore the outer screen is as slow as the inner one.
But probably the performance is poor because I am having about 3000 calendar entries.
After all - I still can't see any device to exchange it with. The inner screen is just to wonderful to browse the web.
the e71 is supposed to have a lot of great features. i think it will take us by surprise. the feature list and a good price can be found at http://shop.nokia.co.uk
Well, I've got both E90 and E71. Despite the difference in shape and screen, I can tell that E71 feels a lot faster than E90. Especially if you watching photos and videos from SD card. Plus E71 longs longer. Please note that technical features are the same (3G, GPS, camera).
So to me it's clear - E90 is for business trips only (when I wouldn't like to have 2 kg laptop with me) and E71 is for everyday use.
i have never been a fan of communicators.. so e71 all the way.. =P
i want to know that there is a limited access in e 71, address book. you cna not add long address. any solution is there . mail me on info@greendot.in
For me personally i choose E71 Nokia Mobile Phone, well actually because the battery life of E71 is much better compares to E90.
I've got one of each as well. I've had an e90 for over a year and an e71 for about four months now. Personally, I think the e71 is faster a lot of the time, but it really depends on what you are doing. Neither is a speed demon, though, and although it is hard to justify jamming the e90 in my pocket, I really just have a special spot for the phone. Tonight, sitting next to me is my e90, the e71 is off and in a drawer. The same thing happened with my 9500 and e61. I loved the e61, but carried the communicator more because it was just... more wow factor. Color me bored with the Black Berry clones.
Well I have both E90 and E71. I have been using E90 for more than a Year and recently got the E71 to test it out. I have been using E-Series from the day E61 was released.
Both Handsets are different based on design and usability. So this is a personal choice. But if one wants to compare the speed. E90 will always win. I have same apps installed on both Sets and clearly see the differences.
Example: I regularly use Widsets to read news. E71 fails drastically in providing a responsive UI.
