Linpack- HD2 vs other Snapdragon Phones

I have noticed that the HD2 gets around 26-28mflops in most of the froyo android builds, but devices like the nexus one with the same CPU manages up to 38mflops. Why do we have this difference? Is it just because android is not optimized enough for the HD2? Can we expect to eventually be able to run Android as fast as the other phones?
Thanks

I'm almost 100% sure that it will eventually be at least as fast as the nexus one..
dude if you look at the white sheet, nexus one and HD2 are almost identical, hardware wise.. the only thing that separates the two are the screen size and of course the operating system for both phones.. otherwise they're the same.. the only reason being why the HD2 is only getting 26-28 mflops as opposed to the nexus one's 38 is because the HD2's android builds are still in beta and running from the sd cards as opposed to the nexus' running from the rom which will always be faster..

Yes, I made it clear that the nexus one has very similar hardware and that is why the linpack scores are of interest. The question is, will these android builds ever be optimized enough allow the HD2 to match native android devices like the N1?

Think you just answered your own question....
But to add to that, of course it will.

I think the biggest factor would be the type of sdcard running the android build in the HD2. The test didnt even mention what class sd card was used in the HD2 tests.
And of course, optimization. I have great faith in our most excellent devs. See how much weve grown by leaps and bounds ina months time. Imagine what the next few months will bring!
Cant wait for a gingerbread build

Indeed, the progress over just a month is very impressive (thanks to all the devs).
I can't wait to get a build which runs off nand and is fully optimized hehe, but I think that may take a few months?

IM running mattc's Froyo-Desire build off a class 2 8 gig sd card, and im getting the "average" 26 mflops.
I wonder how other builds running higher class sd cards are faring?

I'm running Cyanogen off an 8gb class 6 Samsung and I'm getting between 27 and 31 so around 29 on average.

27 on average with 8GB SanDisk C6...

Hmm
Linpack is purely a CPU based performance test. Why would the type of SD card make a difference? Disk access speed is not related
Factors that would impact its performance is the number of background applications. Using SetCPU and a few others.

well linpack is not only based on CPU performance.. it's much more complicated than just the CPU.. it measures the system load, cache size, memory bandwidth, accuracy of the clock, compiler settings etc.. hence, running two different WM roms would sometimes throw a considerable difference in scores.. but i agree on what you said about the performance impact when there are other applications running on the background.. and on this particular OS, everything is being loaded from our micro SD card.. ever notice the loading time difference when you install an application on your micro sd card vs your internal memory?? it might not be that much on small application but on 20-30 mb applications, you'd feel the difference for sure on our device at least..

i am getting 33 mflops on average with a class 4 8 gig sdcard.

Are you using the latest kernals which unlock all of the memory?
I heard people who have got android running with the latest kernals are getting 38-40 mflops now.
I'm running mattc 1.5 with no changes to it, doing 28mflops or so. I have an 8gb class 6 card.

shubcraft 1.2b rom + todays manusfreedom kernel = 35,3 mflop
Crash

i get a sad 19mflop with the config mentioned in my sig. I'm ashamed... (j/k )

I think if you closed your open apps (advanced task killer) and run it again you will get a better score. Run it a few times, I'm sure you will get at least 27+.

mattc 1.5 with 11-08 manusfreedom kernel
8gb class 2
29.845

I got 40 the other day...

In order to compare like with like we need to know
US or European
Size and class of SD card
And which android build you are using.
Now to try mine, I have 3 builds on my SD card.

32 GB vs 16 GB

what are you guys getting? I ve pre-ordered for the 16gb but thinking to maybe switch to 32gb, for I ve heard 32gb is noticeably faster cuz of bigger storage Idk if that is true... This is my first time using android tablet, ditching ipad finally. I know there is an extended sd card option but still would you buy 32 gb for $50 more?

32gb... Some of these games coming out are over 1gb each, and some are approaching 2gb. I like to have things installed and not have to do the install/uninstall shuffle. Plus to have space for other things. All Media and storage go on the 64gb micro sd card though.

I pre-ordered a 16GB black from Best Buy, then changed my mind to a 32 GB white.
Best to have too much than too little.

They kind of want you to buy the 32gb version since the 16gb version is only 50 bucks less. That being said, I think it matters less on a tablet than on a phone because I always root my tablets. There's less downside from voiding warranty because my tablet is always safe and secure in it's case inside my bag while I'm on the run whereas my phone can be accidentally dropped at any time. That's just me though.
The faster speed from having a larger internal sd card is of somewhat miniscule benefit. For something like a 128gb and 256gb ssd, the improvement will be mildly noticeable but not so much on a tiny sd card. Get the one that fits your needs.
I really want a black one because I prefer understatement (don't want to get robbed too). So if I get a 32gb version, it will be because the 16gb version is only available in white in the states right now.

I got the black 32GB from Best Buy always nice to have extra, also have a 64GB sd card for it.

changed to 32 gb...lol

I was on the fence about getting which one to get too. I decided to get the 16gb because of the Amazon $50 gift card promotion. I don't game alot, so the huge app sizes are not as much as an issue for me. I will put in a 64gb sd card for videos and pictures.

i never game as much as i think i'm going to and always have tons of space left over, lol. i bought just about every emulator and a bunch of games, most of which i've never played or never installed.
i did preorder the 32GB for two reasons - 1: if i want black and by the 11th there's only one choice
2: i swear i'm gonna start playing those games i bought, lol
i also bought another 64GB sd for media. i got a 64 in my ativ 500t and 700t but only a 32 in my gn8. the only reason my phones have 32gb is b/c tw roms are crazy huge compared to AOSP and nandroids are taking 4GB a piece! otherwise 16GB would have been enough.

I feel you about the size of the tw roms. Hopefully, there will be root and a streamlined tw rom to help out a bit with that.

For SSDs why is there any benefit to speed based on size at all? I assumed the OP was just confusing RAM with storage.
For magnetic HDDs, bigger is faster for the same amount of data because on a bigger drive more of that data can be stored towards the edge. The edge of the platter moves quicker, so you get faster R/W times.
Why would different size SSDs have different speeds?

You get faster speeds on larger SSD drives because of the way the controller works. There are more cells working in parallel which increases speed. Each individual bit of information acts rather slowly in emmc and is pretty consistent across devices as long as the type of Nand is the same. It's the controller which makes the difference in speed and the controller is better when it has more parallel units working in tandem. So in the SSD world, bigger is better.

32g enough for video games

Moto X Play (16 GB) with 11 GB and 10.89 GB internal storage?

First time when I've ordered Moto X Play (XT1562) with 16 GB of internal storage, it did show 11 GB of available storage. However, due to display defect, I had to return it and get an replacement which has 10.89 GB of available storage.
I've received the replacement before sending the actual defective one. I've tried to check what's different, but I couldn't find anything else except for storage availability difference. Both were Lollipop 5.1.1 with identical kernel and firmware version (both were "reteu" and single SIM). As I didn't know about accessing recovery mode before returning the defective one, I don't know was there any difference in recovery information.
Performance seems to be identical, both were still causing identical lags. Even after upgrading to marshmallow with my current replacement, it's still stuttering while scrolling. It still doesn't feel fully optimized.
I didn't post this before as I thought that this wasn't a big deal, but I want to know what was the difference between storage availability. Does anyone have Moto X Play with 11 GB of available storage? I saw some people having 10.89 GB, but no one having 11 GB. Please check size of your available internal memory storage and give some details if possible. Along with that, vote if you have 16 GB model (If you have 32 GB, don't vote for other value).
What happened to 0.11 GB of storage? Is it anyhow possible to get it back?

Well, mine does have exactly 11GB. Dunno what's the actual reason.

I'd imagine it's the same as anything, all chips are made to a certain spec and not all are bang on. They have tolerances, some maybe 11 and others maybe 10.89 and some may even 11.10 or something. It's the same with CPUs, not all chips are identical I the same range. This is why we CPUs can be over clocked much further than another CPU that is the same model number.
If after a few days you don't see a noticeable performance difference, I'd suggest performing a factory reset. If it still persists, I would send the pone back. Mine went from noticeable lag to occasional stutter (fairly rare, just could be equated to background tasks running).

It's not the same as CPUs.
If you have two same phone models with same CPUs with advertised clock speed at 1 GHz for example, and then you notice that they underclocked it at 800MHz on one phone due to possible instability with higher clock, wouldn't that be unfair?
You can't just sell something advertised with higher specifications and then sell it with lower specifications.
On contrary, if the manufacturer manages to get higher clock on some CPUs, they would sell those as different model with higher advertised clock speed. The example for that would be MSM7227 (600MHz) and MSM7227-1 Turbo (800MHz, same as MSM7227, but works with higher clocks). Some models only use the first one, while other ones use the second one. Two different phone models can have different CPUs, but two same phone models cannot.
It's still 11 and 10.89 GB. No one mentioned anything more or less yet.
You're suggesting something that I didn't ask for. I don't need help with my phone. I need help with finding out what is causing this and is there anything possible to do something with it.

I've already said there was no difference between both phones I had. Same region, both had only single sim slot.
Further note:
I've decided to check with file explorer to see actual partition sizes:
/data: 10.89 GB
/system: 2.57 GB
/cache: 0.73 GB
Total: ~14.19 GB
In case that others have 11 GB of /data, then that would be ~14.3 GB in total for them.
If you can, check /system and /cache partition sizes to see if you get in total about 14.3 GB.

Okay. I'm sorry to have responded and tried to help you out. If you think that I don't know what I'm talking about then I'd say you are obviously qualified to figure this out your self. I wasn't trying to be rude, just trying to explain that there are tolerances in ICs that are followed. They have gotten a lot better than when CPUs were first being built, I understand that. But there are still tolerances. I very rarely see two Memory ICs with the EXACT same storage size. There are sections of the disk used for error correction that we don't even see in the storage size.
If you are unhappy with my response, that's cool. I won't be responding anymore.
Take care.

I'm not sure how I aggravated a snarky response, but I'll apologize for it.
Re: your analogy question with Windows 10, I answered yes there is a difference. Because after upgrading from 4gb to 8gb, you wouldn't want to sell yourself short by installing an x86 windows and be limited.
I'm not familiar with Android architecture, hence why I was posing this question about if if a 6gb/8gb version would impact compatibility with ROMs. Judging by your response, I'm guessing that's a no.

Sorry. It's been a Monday. Didn't mean to snark. (Lord I hate Mondays...)
IMO, there is little need to go above 6, let alone 8. But, if they're going to offer it, take advantage of it. The more you have, the greater number of apps can stay in flight, which also means less the OS has to constantly load from storage, etc.
A lot depends on how the OS handles RAM too - like how the Sammy GS7 had very aggressive RAM management when it came out, and it would close down background apps WAY too soon. Users noticed switching back and forth between apps took longer than it should because each time they switched apps it had to load it from storage back to RAM, which is very slow in comparison.
Then there is the strange concept some people have that you want to keep your RAM and background apps clear for better performance. A self-inflicted GS7 problem as a performance increase... *boggle*. If you examine how RAM works in a typical computer, it pretty much debunks that thought. Once data is in RAM, it's pretty CPU and power neutral (unless being called on). The argument can easily be made that it is more resource intensive to constantly load from storage into RAM, then clearing it asap, than it will ever be to simply accessing data already in RAM. My thought is the only bad RAM is unused RAM, so just let the OS do it's thing.
But regarding your question - no, the ROM probably doesn't care a lick how much RAM the device has, as long as it is enough to load itself, services, and the apps you want to run.

Anybody got 8/128 variant?

I've ordered the 8/128 version because of the color and because i don't need 256 storage. There is difference in performance between 8gb and 12gb ram variant? how result black version in real life?

I just got mine today(8/128) an hour ago, but unfortunately I'm in work, do can't test it just now.
According to the specs, only the storage and memory capacity is different, nothing else, so there should be no performance difference between the 8/128 and the 12/256 version.

Let me know when you test it, i will it receive next week

Both variants will perform the same in almost every thing you through at them.. I almost went the same route for the green color but ordered the blue today cause I'm a spec nerd. I need the extra storage is the main reason..
