There is NO 1GHz i8910HD, Updated

with 3 comments

Update: If some research and a dab of common sense weren’t enough, Samsung India has taken down the 1GHz line from the product description and replaced it with the proper specifications listed below.

Recently, a lot of mobile blogs and forums have worked themselves into a tizzy over Samsung India posting the specs of the 16gb i8910HD with an added line that reads “1GHz CPU Powering Innovative 3D UI” and jumping to the conclusion that Samsung put in a newer, faster processor for this release. For those that bothered to look into the actual CPU hardware used in the Samsung i8910HD, you might have noticed this line:

OMAP3430 – 600 MHz ARM Cortex A8 + PowerVR SGX 530 GPU + 430MHz C64x+ DSP + ISP (Image Signal Processor)

Paying attention to the bolded numbers, neither of them come close to 1GHz. It’s only when you add the clockspeeds of the main CPU and the DSP that you get 1030MHz, or 1GHz. That’s all well and good, but NO other mobile CPU is clocked in the same manner. If they were, then that means the N97 is running at 694MHz, the N95 is clocked at 552MHz, and the Palm Pre is clocked over 1GHz.

It also means that EVERY i8910HD on the market has a 1GHz CPU as well.

TechRadar’s post regarding the same topic digs a bit deeper and reminds of Samsung’s previous history with errors on their own website. I’m reminded of Nokia copying and pasting information from the Euro device specifications onto the NAM device pages without bothering to change even the frequencies.

Still don’t believe me? Consider the contrary. Pretending Samsung DID change the processor  it would be a production miracle if Samsung was able to…

A-1. place an order for X,000 (or more) new Qualcomm chipsets (including all of the licensing and purchasing details from TI), OR
A-2. rush their own 1GHz Hummingbird CPU into production a few weeks after it was announced,
B. re-write the drivers necessary for the hardware and operating system to work properly with the new chipset,
C. re-manufacture the next batch of i8910HD’s with this new chipset, and
D. do it all within the 2-3 months the original has been available.

There is NO 1GHz i8910HD. Or, if you like, ALL i8910HD’s are 1GHz. You decide. Either way,

it’s the same device.

Nokia N97; Multimedia Computer…from 2007.

with 4 comments

Since my last post about how much more interested I am in the Samsung i8910 instead of the N97, I have given both devices a lot of thought to try to come to a fair decision. Since my day typically consists of significantly more messaging than anything else, a hardware keyboard started to look pretty appealing to me. Then the rest of its lesser features when compared to the i8910 started making me thing that maybe they would be “enough” for my normal usage. That was until this was published on Forum Nokia regarding the hardware in the N97:

If it wasn’t bad enough that Nokia is using the same 5mp camera sensor that they’ve been using since the original N95, they also used the same processor used on most Nokia devices since the N95 from 2007! If you think I’m making it up, please take a look at the processor specs of the original N95. Not only is it the same processor, but the N95 also supported a dual CPU and a dedicated 3D hardware acceleration (making it excellent for gaming).

Meanwhile, everybody else has stepped up to processors that can at least support up to 600mhz (if not more) for their future devices, if they’re not using them already. Among them happens to be the Samsung OmniaHD which not only features the Cortex A8 process (capable of up to 800mhz), but also uses the PowerVR SGX GPU for graphics acceleration. You might reconize the Cortex A8, as it’s the same one that Palm is using in their hotly anticipated Pre due out from Sprint within the next couple months. If you’d like to see the nitty gritty on the difference between these two processors, do a search for “Pre” and “N97” on this Wikipedia page.

I know some of you may be thinking that a faster processor means significantly less battery life, which turns out to be very ironic. The Cortex A8 also features dynamic power management, meaning it can adjust its power consumption based on the CPU load in real time to significantly save battery life. The entire ARM11 architechture doesn’t support anything like this.

This has pretty much put the final nail in the coffin for me. I meant it when I said I’d like to keep my next device for at least a year if I can, and I just don’t think using old tech with a higher clock speed is going to be able to cut it for a long-term device, especially when the competition has so many other features under the hood as well.

What do you think? Will you still buy an N97 knowing it’s using an older processor than most of the new devices due out this year?
