32A vs 32B

Hi guys,
I wanted to know which of these versions is better. 32A has more RAM memory, but 32B has better chipset, with 65nm technology, but same speed.
If I could choose, which one should I get? 32A?
Thanks you!

32A have the 7200A CPU and as far as I know it's a 65nm.
From the wiki:
* PVT32A handsets have 288MB total RAM (192MB usable by OS - same as Hero handsets) and use the Qualcomm MSM7200A CPU.
* PVT32B handsets have 192MB total RAM (96MB usable by OS) and use the Qualcomm MSM7201A CPU.

PVT32A should be based on 90nm architecture and PVT32B on 65nm.
I'm not sure if it makes more difference than the RAM size.

dun understand why htc used a poor processor for their newer phones?

I thought they are essentially the same processor but with 65nm technology (which in theory, should consume less power but not sure in this case)?
Speed-wise, is there any differences between the two?

Or why they reduced RAM size on PVT32B devices... They used newev chipset (yhbae01 is right - same speed but less power consumption, and a bit better performance) but reduced RAM...
Anyways, anyone knows answer to my question? Is PVT32A better than PVT32B, and WHY?

You also need to take into account the radio frequencies. As far as I know, the US T-Mobile devices (32B) have less RAM but run on the 1700/2100 MHz 3G frequencies, while the Canadian Rogers devices (32A) have more RAM but run on the 850/1900 MHz 3G frequencies.

before buy
Hi,
i am located in the EU and have the possibility to buy either 32A or 32B which supports my 3G network (only from ebay). i found that 32A-s are really rare and are about 1.4x more expensive than 32B-s. its that +~100Mb RAM so important it is worth to pay for? i am a little bit confused till i have read about the swap to SD possibility, the better processor of 32B etc etc. could someone experienced with magic give me a clear understanding on the 'real' difference of the 2 types (i know all the technical specs).
sry for my english

Speed wise I have never heard any discussion of 32A or B being different. Ditto for battery life. The RAM is a the big deal. Lets you run more apps without worrying about swapping. The phone definitely gets slower once it starts swapping apps in and out. If I had the choice I would get the 32A over the B.

Hi,
thank you for the information. So you think i would feel the lack of RAM on 32B... and what about 32A, will it run out of memory sooner or later, or under normal circumstances will it be enough?
thank you in advance

66 apps (assorted games, tools and productivity) and still have 213 Mb available. Apps with really big data requirements (GPS with local maps) tend to have their datasets on the SD card and many apps also use the SD for storage. So I would say you are good for Flash memory space. You could solve this with Apps2SD but most 32A ROM developers s don't see the need/demand.
In terms of running apps, you will notice a slowdown once the RAM gets filled up and swapping becomes an issue. Just install a task manager (liek TasKiller) and kill running apps that you don't need at the time. Once launched, apps continue running until you end them and most apps are designed without a quit/end function so they stay resident in memory.

Oh, C'mon! Doesn't anyone want to field the *real* answer?
If you plan on using a "stock" ROM without the HTC SenseUI, a 32b should be *ok*...
...but if you'd like the option of have SenseUI be lag-free (or more so, anyway) a 32a device is a better option.
Either way, how can you argue *against* the extra RAM?!?!
Here's an example:
I have the option of buy a new PC with either 4GB of RAM or 2GB of RAM...which one is going to feel "snappier" or more responsive?
Answer: the one with more RAM.
I've used a stock T-Mobile G1 to run SenseUI and it was *painful*. The ROM devs have made an insane amount of progress, and I'm sure that HTC has taken advantage of some of that.
I'm now using an HTC Rogers Magic (32a) on AT&T in the U.S...on which Sense runs *much* more smoothly...but I still prefer the Cyanogen ROMs, as they're more responsive still.
(it's for sale, BTW)

Well there is a little more into it than the Rom itself. How many apps and widgets you have running and how much ram consuming is the apps/games you're gonna use. I know that you have have task managers and so on but if i'm a businessman who need and want some apps to be running in the background constantly i would defiantly feel a difference from the 32a and 32b even when running a stock rom without sense UI!

From as far as I have read (hours of googling). both msm7200A and msm7201A are 65nm.
What I have read:
The A is 65nm and non-A is 90nm.
7200 is before the patent issue filed by broadcom and the 7201 has a patent issue workaround.
The workaround has a small performance impact from what I have read.

(p.s. sorry for the bump of this old thread, but I was googling on several overclocks of these cpu's and came across these details as well. So I tought it would be interesting to share ...)

Meminfo ?

I may be missing something, but on my Nexus One, doing `cat /proc/meminfo` shows Memtotal: 217812 kB
Huh? I thought this phone had 512 MB

it does. alot of the ram is reserved for the Android OS. Similarly, the mytouch 3G had 192MB RAM but only 97MB were usable by Applications.

That's a lot of reserved ram, Odd that my friend's Droid shows MemTotal: 230860 kB
Can you confirm that my value is correct for the Nexus One? I want to be sure before I root and void the warranty (In case of bad RAM)

its correct, theres been at least 2 other threads about this. also if you had bad ram you wouldnt be seeing a lower amount of ram, you simply would experience alot of crashes (assuming the phone even started up)

I apologize for the duplicate thread. Seems my searching skills are not up to par....
Thanks for your help.

how do i know how much ram ?

i have got in my magic?
when i open task killer i see 120 M free when noting is on
when i use memory booster i see total memory 201.875.456 and
free memory 130
and when i enter to the available spave in the setting i see 165
so much much i have?
its version 32a
and i know that its suppose to be
512 rom
and 288 ram
but i dont see 288 in no where
so please help
thanks

strange i download a program that said that in total i have 192 ram
but this version is 32a and what iread its suppose to be with 288 ram
what shell i do ?

htc magic 32a (without google brand) and without 3.5mm jack.
should have 288mb ram.
SAPPHIRE PVT 32A SHIP S-ON H
htc magic 32b with google brand and the htc magic 32a with 3.5mm jack, should have 192mb ram.
SAPPHIRE PVT 32B SHIP S-ON G
SAPPHIRE PVT 32A SHIP S-ON H

as you said i should have 288 RAM
but i read that the designs in israel they bring the 192 RAM
and the programs say the same
didnt see even in 1 place any 288 RAM or 512
and its 32A indeed
but everything else match to 192 RAM
lol really dont know what to do
btw
there is even any diffrence betwean the RAM ?
shell normal person that use some programs will feel the DIF?

Not much in difference. Some try different roms to get different speed. Plus all depends on how much Widgets and shortcut you spam your home screen with plus animation backgrounds.
sent from myTouch 3g 1.2 using XDA app

lol noting speical 1.5 android with 192 ram ...
working fine and smooth dont see any problem
but still i am with the origin rom

It is something that has been bugging people for a while but there is a part of the RAM that is "System reserved" and will never show up in any app.
192 mb is the usable RAM on the 32A, the rest is reserved. You could never see 130mb free on a 32B as it only has 96mb of usable memory

ohh nice.
so you say me that normal i have 288 RAM ?
i will be so happy

yes you have 288mb ram, only 192mb is addressable by the OS. the other is used for the system such as the gpu, camera etc etc

nice! thanks
well 192 is enough and sometimes i use the clean rams programs its free alot ram and always use task manager killer
and everytthing working fantasty

[Q] Locked RAM - is it possible to unlock?

Hey there!
I've read, that the gt540 comes with 256mb ram, but you can only access ~160mb on stock roms. Is there any way I can unlock the remaining ram without installing a custom rom? (I have the 2.1 stock rom) Thanks for any replies

Sorry, It only has 128MB of RAM.

That's wrong. It has 256mb. You can only access 160mb, because the rest is used by system I think.

Actually, I was wrong, it has 158 MB of RAM. and 139 is available to user.

If it had 256mb ram
LG Would of Released Android 2.2 if the GT540 had 256mb of ram. Proof, LG Optimus One

Our phone has 256mb of ram, but we are able to use only 160 beacose the rest of it goes to video chip for rendering. In lg optimus one video chip have his own ram.

It does not have 256MB of RAM, otherwise we would have well over 100MB of free memory w/o odexing 2.2.

Lear to read system can use only 160 beacose rest is reserved for graphic and other components. You will never see this ram. In our phone memory chip is 256MB and that is a fact.

its possible to hack into the system and change the amount of MB's. but it can only add like 5 mb, and i am not gonna spend my time hacking my hardware to add 5 mb

Actually, there is no way to physically hack the RAM to give you more, it's just not possible. Although it is possible to add virtual memory, but this will kill your phones Internal NAND Memory or SDCard quicker as the read/write cycles will increase dramatically.

[Q] (Q)T-Mobile hd2 shows 403 MB RAM

I have T-Mobile HD2 with T-mobile logo and colored buttons. But ram size and device memory size shown low in hardware info. I have 2.0.8 HSPL.
Is this a fake T-Mobile..
Hardware info:
RAM: 403 MB
Device Memory:663MB
SD:14,2 GB

running android? all hd2's show around 400 - 411 meg ram when running android.
Also, the first 128 meg is taken by the graphics hardware, so it is only showing 40meg lower than expected, not 160+

Yes andoroid is running on it, I read about 128MB ram but still 40 MB is lost. and why device memory is 663MB . mgldr and clockwordmod is also installed , is it related with them. Is there a way to see the physicall memory from android .
thanks for the replies
