How to tell if a Prime is version G1 or G2?

[kevin3g]

Hello, I have a Prime and was wondering which version I have. Is there a way to check this?

Thanks

The G2 has embossed the "G2" on the back.
Under "Help" -> Tree -> About all revisions up to and including "C" is G1.
Rev D is G2

The HW version is also output by the VERSION(2) command.

What are the advantages of the G2 anyway?

Hardwarewise:

G1 uses a 400 MHz Samsung S3C2416XH-40 (ARM926EJ core, ARMv5 architecture)
G2 uses a 528 MHz NXP i.MX 6ULL MCIMX6Y2 (Cortex A7 core, ARMv7 architecture)

G1 has 32 MB RAM, 256 MB flash
G2 has 256 MB RAM, 512 MB flash

G1 battery: 3.7V/1500mAh/5.55Wh
G2 battery: 3.7V/2000mAh/7.4Wh

Softwarewise it runs at about 3x the speed of the G1:

Also, if you buy a G2 you know you will have a more readable keyboard.
If you buy a G1, you don't know which keyboard you will have without further checking.

What do you mean "you don't know which keyboard you will have"? I have a G1. Are the keyboards made differently?

The more readable keyboard has a darker blue paint scheme, this post shows the difference:

There are two hardware declensions of the first generation (G1) Prime. Rev. A and Rev. C (there was no Rev. B that I'm aware of).

All of the Rev. A and some of the early Rev. C units had the wishy-washy, barely visible colour scheme. Later Rev. C and all Rev. D (G2) Primes have the much better contrast markings.

It's doubtful that there are still any Rev. A models on the market. There are still some Rev. C models available, notably in the Americas. If you buy one of those, you won't know what colours you're getting until you unbox the unit. If you buy a G2 (Rev. D) then you're sure to get the better colour scheme.

Amazon.co.uk still have some listings with the Rev. A model number NW280AA, so maybe! One of the listings offers a selection between "HP Prime" (NW280AA) and "HP Prime -New Model - International Pack" (G8X92AAB1S). There is a separate listing for the HP Prime G2 but about £15 to £20 more than the others (perhaps to try and shift the older models).

I wouldn’t be too sure at all, I picked up a very very cheap (brand new and boxed) Hp50g six months ago , and it turned out to be old stock that had a free 1GB MP3 player in the blister pack. (I know it was old stock because I bought the very same version several years previous to this recent one!)
The MP3 player is truly ancient compared to modern variants. The 1GB is a dead giveaway to its age.

Some stockists just stock a SKU and pay little attention to which version it is, it might have also changed retail hands several times before you buy it.

The last G1s produced had the higher-contrast keyboards but many vendors still have unsold earlier models with the lower-contrast keyboards. Unless you are dealing with a knowledgeable vendor, it's a crap shoot as to which keyboard you'll get.

where can you find this specs in a official HP link

To this level of detail, nowhere.

Newer data sheets will list more flash and RAM, but from HPs perspective they are basically the same thing. Just one is a bit newer and has slightly tweaked internals.

When I try to run that benchmark, it asks for opts and no matter what number I put in there I get an Invalid Input error. I have both the app and the program on my virtual and physical calculators and both do that.

Hello

I find that the easiest way to know which version it is is to reboot it. The G1 has an animation with the HP logo, a cartesian plan and the x²+y²=1 equation.

The G2 has only the HP logo.

Nice to know it. Do you guys know options where can I buy the real G2 one by internet ? Guys HP have just created a messy situation where we can find 4 different models in the market with a tiny difference between them , a perfect scene for bad vendors make money.

[Dougggg]

I believe the model you want is 2AP18AA maybe some one with one can comfirm. Looks like amazon and best buy have them
