The difference between a 5450 & 5550

[wocket]

Right this is a real no brainer but humour me all the same.

From what I have been reading there appears to be no hardware differences between the 5450 and the new 5550.

Except for the new OS on the 5550 and a 4 replaced with a 5 :lol:

You see i'm thinking of getting a 5450 now that it is cheaper and then getting the free update. :)

Would I be correct or am I missing somthing?

[orcas]

The 5450 has only 64 mbytes of ram, the 5550 has 128. Apart from that, i thing the two are identical machines.

[PR.]

The iPAQ 5550 also has a PX255 CPU with improved memory bandwidth over the old PX250 that are in the 5450. Until someone does some benchmarking of a 5550 running PPC2003 with a 5450 running PPC2003 we won't know how much of a performance boost will be seen

Hope that helps

Thanks for clearing that up guys.

I might just hold fire and wait for the 5550 to come out and convince myself that I really need it.

I would just wait since you get double the RAM and a faster processor bus. If you really want one now, I would be willing to sell you my 5450 and do the waiting for the 5550 myself :)

The 5550 don't have CIR nor Nevo (universal remote software).

[madbart]

Are you sure about the consumer IR not being included?
What a stupid move. I use mine with Nevo & TV remote on a daily basis.
If this is the case i will keep my 5450 and just buy a larger SD Card! :cry:

[Palmguy]

That's right...no CIR or Nevo :| Sorry!

I will say that the combo of PPC 2k3 and the PXA255 is definitely worth it!!!

"Universal remote control (CIR) :

Why was the Nevo application removed from the iPAQ Pocket PC h5100/ h5500 series products?

The iPAQ Pocket PC h5150 and h5550 products are targeted at our business customers that don't value the NEVO capability. HP believes the Nevo application to be of great value and is better suited with our iPAQ Pocket PC h2200 series."

Someone over on bright hand posted the following, nobody has got any proof yet buy he claims he got this response from HP

Good News!

From HP, "The iPAQ H5550 handheld pocket computer (product number FA107A #8ZQ) has Consumer IR (CIR) and IrDA ports."

From what i read of the HP FAQ is that the NEVO application has been removed. It does not categorically say that the CIR has been removed.
One would assume that it would be easier to build the units based on the same IR chip.

If it is still a CIR it will allow the use of 3rd party application such as tv remote control from PDW Win.

I suppose we will just have to wait and see

[Jerry Raia]

I use a 3rd party app on my 3835 for this and it works fine.

[bmceachen]

I have never used the 5450's CIR package but the IR device on the 5550 is terrible. I get a max of 5 feet range with the TV remote controller from www,pdawin.com and it still only works 60% of the time at that range.

[KayMan2k]

Finally confirmed from HP - the 555x does not have CIR - it has slow infrared (SIR)

A strange ommission as the 5550 seemed to be essentially the 5450 with new O/S, extra RAM and newer processor. You would have thought the CIR would have remained by default!

[Jerry Raia]

I never used CIR much, do you think it was popular? Maybe they left it off the 5555 cause it wasnt.

I don't know about a 5450 with PPC2003, but the 5550 is MUCH faster than a 5450 with PPC2002...

And it should be. WM2003 is designed for XScale. PPC 2002 was not. that in and of itself should make the new devices with the new OS blaze past legacy devices without looking back.

However, I agree that until you see the new OS on the 5400 there won't be a consistent comparison...

I would think more people used the nevo than bluetooth. I use both. :) And becuase no CIR I'm not upgrading to the 5555. :(

[Janak Parekh]

And it should be. WM2003 is designed for XScale. PPC 2002 was not.
Actually, from what everyone's saying, WM2003 is ARM optimized but not specifically XScale optimized. That's why the 1940 can run WM2003 even though it has a Samsung chip.
