As enthusiasts of the N900, Palm Pre, and Motorola Droid alike know, the 600 MHz clock is somewhat conservative, as many have been able to get up to 1 GHz relatively easily with custom ROMs and other kernel patches. In fact, the OMAP 3440 has a recommended clock target of 800 MHz, some 200 MHz higher than the recommended 600 MHz target for the OMAP 3430. Notably, the OMAP36x series running at 45-nm has recommended clocks of 720 MHz for all but the highest end OMAP 3640, which is 1 GHz. It's entirely likely that the difference between the OMAPxx40 and the lower clocked OMAPxx30 for each process target is binning, possibly explaining why some are able to get devices running at even over 1 GHz.
Of course, the primary comparison for this generation is arguably Qualcomm's popular Snapdragon SoC. The primary differences between these two popular SoCs are two things: the Qualcomm SoC includes celluar modems, but more notable is the difference in GPU. We've talked briefly before about how the QSD8250/QSD8650 both include Qualcomm Adreno 200 GPUs which are actually re-branded AMD z340 GPUs brought over with the IP Qualcomm bought when it acquired AMD's handheld graphics and multimedia assets division. Interestingly enough, the AMD z340 is related to the Xenos GPU in the Xbox 360. Standards support wise, however, the Adreno 200 and PowerVR SGX 530 both target OpenGL 2.0 ES, but performance wise we now know the PowerVR SGX 530 is superior performance wise over the z340. Keep in mind the iPhone 3GS has a slightly higher spec'ed version of PowerVR SGX GPU, an SGX 535.
It's difficult to be absolute about how much the performance delta between the Adreno 200/AMD z340 and the PowerVR SGX530 really is, as so much of the difference is the result of driver differences. Add in further complexities surrounding how well implemented features are on different smartphone OSes, and it becomes even more challenging to give you a real objective answer. Point is, without a common software stack, it's difficult to give a solid benchmark. That said, it's hard to argue that Imagination's PowerVR SGX series isn't faster in practice across the board.
Of course, the untold story here is that although the 3430 ships with modest clocks (which the Motorola reduces by 50 MHz), it has seen largely uniform overclocks to 1 GHz. In fact, what's really interesting here is that in principle, a 1 GHz OMAP 3430 should outpace a 1 GHz Snapdragon SoC in a number of use scenarios because of the vastly better GPU onboard the 3430.

I've got my N900 clocked to use 250Mhz idle and 805Mhz stress clocks and it fastens everything by huge amount. 600Mhz is sometimes a bit slow and if you up it a little bit, everything starts to get smoother..The custom kernel is using lower voltages but higher clocks than nokia stock kernel.. which is why 805mhz drains just about the same amount of power than 600mhz with stock kernel.
I just love the fact that you can do that kind of things on this phone..
One guy was asking how to backup sms messages.. well there wasn't any app for it so you could just run a command with sqlite in Xterm to search through the database for all sms's and forward the results with > to a text file :)

That's a truly epic article, the in-depth look at both the hard- and software side of things is far and above what I'm used to reading regarding smartphone reviews. Many thanks for that!Looking forward to similar articles in the future.

Epic, right, and you don't care that Apple's device is visible where it has advantage but is not shown, where it doesn't. Like on contrast comparison images.Misterious.

No, can't say I mind that at all really.Then again I'm not in the market for an iPhone anyway.

I actually completely spaced on that one - I probably had a 3GS in my pocket when I took those photos.There's no conspiracy - I just thought that the Incredible's AMOLED display would make an interesting comparison with the Motorola Droid's LCD, and the N900's resistive layer would mix things up a bit.
The iPhone screen really shows its age in the numbers from the bench though. It leaks light pretty badly and obviously the lower PPI is... well... bad.
Cheers,
Brian

Nokia has been making devices that work without much hoopla for a long time. It is not for everyone but it beats the available iPhone in more useful ways than is possible.Helmore - Friday, June 11, 2010 - link
The Adrena 200 is based on the AMD Z430 GPU. A Z340 does not even exist AFAIK.I know, I'm nitpicking here, but I just thought I had to mention it.
The Adreno 200 runs at a frequency of 133 MHz, giving it a theoretical performance of 133 MPixels/s of fill rate and 22 Million Triangle/s. The Adreno 205 is the same core but running at 200 MHz and is what will be used in the MSM7X30 and QSD8X50A (45 nm version of the current Snapdragon chip with some small tweaks). The SGX530 used in the Droid (OMAP3430) runs at around 100 MHz, which should give it a theoretical fill rate of 250 MPixels/s and a 7 million Triangles/s. On the OMAP3630 the SGX530 will run at 200 MHz AFAIK. That's all theoretical performance, as we all know they're only part of the story. Just take a look at the GTX480 and the Radeon 5870 and you'll know that theoretical performance doesn't get you very far.

1) there was a mistake on the N900 hardware page: it's a 3.5 mm jack, not a 1.8 mm. You probably mixed it up with 1/8"2) The N900 can do Video calling over 3G, like most 3G phones in Europe have done since 2003. It works ok, but it's hella expensive, so no one does it more than once or twice.

Fixed! Thanks!-Brian

Lies! It cannot make a 3g video call.It can make a skype video call (or a google chat video call) over a 3g data connection but this is not the same thing. Not nearly.
I've had my N900 since November and this is the 1 thing I really miss.
