Anyway the hummingbird will catch up to g2 processor

I know we have gotten to as high as 1.3 ghz but can our processors reach 1.4 or 1.5 ghz I know battery life would suck...but sometimes its cool to not have these other phones kick the crap out of us...haha

Aye aye aye....
Unless the G2 was running Android 2.1 (which it never has been) it's virtually impossible to compare the two. Ghz mean nothing...
Wait until the Epic is running Froyo and see who needs to catchup to whom.

Not to mention that not all g2s can even handle over 1ghz, they've got a much weaker gpu and the hummingbird has been successfully rooted up to 1.6ghz, but its nowhere near ready for prime time
Sent from my SPH-D700 using XDA App

The hummingbird can be clocked to 1.6hz and the gpu can achieve 75+fps on both neocore and nenamark (after having the fps cap removed.)
Is this not enough for you? We are still in 2010...

Team Whiskey has put out a Vibrant kernel (alpha) than can hit 1.6Ghz, and they're working on 1.8 and 2.0. Once they release the code (which should be soon), it shouldn't take long for an Epic version to surface.

Is stability not a problem with these high overclocks? I don't understand how someone can just put out a Xghz kernel for everyone to use. Aren't there hardware limits, ones that will be arbitrary device to device?

Not unlike desktop CPU overclocking then.

Well yes and no...every one can be overclocked...it boils down to how much..and how well of an over-clocker a chip is..then obviously it boils down to manufacture quality aka luck of the draw.
For example...the 1st gen snapdragon is a sub par overclocker...while the 550mhz chip in the original droid is an awesome overclocker....
It kinda boils down to the manufacturer limiting the frequency to a certain amount..sometimes for stability..but often times to charge you extra for more mhz...Intel has been doing it for years selling the same chip in 3 different clocks when in reality it is exactly the same chip.
I mean if samsung wanted to they could have easily released it at 1.3ghz..they just had no reason to...

just wait till the Epic is running 2.2 and u will see who the real winner is

the biggest issues for smartphone ocing are heat n battery, cuz unlike a desktop were u can keep uping the volts n if it gets to hot just add more cooling, a smartphone is all passive so you cant go much above stock voltage or it'll melt, plus wht good is 2ghz if u can only run it for an hour b4 ur battery dies

So then why is it such a big deal to make a ROM capable of a high clock? Someone could make a 5ghz ROM, but it would never work. If Hummingbird CAN go to 1.8ghz, I don't see why the current overclocked kernel's don't already reflect that.
In other words, I think we shouldn't hope for much over 1.2ghz, which is already pretty good.
Any stability testing programs for Android? Or is everyone saying "no crash = must be stable"?

Tegra2 Underclocking

Can someone test if underclocking works using setCPU.
I believe you have to be rooted.
I live in Canada and it hasn't been announced here yet.

This should probably be merged with the overclocking thread or locked, but I believe they are discussing something similar there.

I don't think setCPU works with the tegra 2

Thank you guys.
But can someone that has received the Atrix test it out.

I've tried to use setcpu it forcecloses everytime.

The Dell Streak 7 also uses this chipset. It is underclocked stock to 800mhz. Maybe you could pull their work apart and come up with a script. I honestly know nothing about it so I probably sound stupid, just an idea.

Where did you hear it was underclocked to 800Mhz? Every review and the official spec sheet says 1Ghz Tegra 2 processor.

I could be wrong, but don't you need a kernel that supports under and over clocking before setCPU is actually useful?

you cant have 2 cores running at different speeds.... nor could i see why you would want to. if you want to increase battery life you would throttle both cores, like you do on a laptop when you want to get some more juice.

No need to worry. developers will get this tablet to at least 1.5ghz or more. overclck tweaks for transformer prime should work on this also. all it'll need is root

Do we really need to overclock this? I mean I probably will anyways but a 1.3 Quad is pretty zippy by itself!

As the tegra 3's gpu compared to say the galaxy s3 (international) is fairly weak, I only hope we can OC the GPU by enough to make a difference. I am not that bothered to about OCing the cpu but I do care about the GPU

The Tegra 3 used in the Nexus 7 is a version of the Tegra 3 chip that didn't work within guidelines at the regular speeds, but were within guidelines for a lower speed. This is done regularly in Intel/AMD CPUs as well. That's why there are different speed CPUs in the same model family. This way they can sell the high speed CPUs at a higher cost and still make money off the CPUs that can't run as fast. Eventually the process to make the chips will be so efficient that they will artificially lower the speeds to sell as the cheaper version and that's when you can overclock like crazy and not have instability (if the CPU product cycle lasts that long).

This suggests Nexus 7 probably won't OC so well. Which wouldn't surprise or disappoint me. It appears Asus dropped a lot of little features to keep cost down(which I think is a good move), and using CPU s that didn't bin well is one good way to keep cost low.

Sure but they say that the Kyocera ultra is coming out soon with a new snapdragon 800 plus with an advance CPU and it makes great decaf coffee too. Should probably wait for that one.

if xda dev enable all 8 cores running performance should be same as 2.3ghz s800
even if 4 a15 clock at 2ghz should be same as 2.3ghz s800
but adreno 330 better than the adreno 320 and 533mp3 for sure

This is only my guess, but IF that was even possible to run all 8 cores at the same time it most likely will not run at full speed because of the amount of heat that would be generated by running all 8 cores at once.

Lol please stop talking. The exynos octa smothers the s600 in benchmarks while at a lower clock.
Anywho, there were some leaked benchmarks a little while back I saw
(Don't remember where) for the s800 and it hit slightly higher than the Tegra 4 on antutu. But it also was clocked at 2.3ghz where as the t4 was 2 ghz.so to answer your question no, the s800 really isn't anything special compared to a15 chips, and exynos outperforms tegra. But the krait chips probably have slightly better efficiency. So maybe it might be worth looking into, the gpu (330) will most likely outperform the power vr marginally, not that it even matters at this point. From the bit I researched the s800 doesn't deviate too greatly from three s600 aside from higher peak frequencies and large band width

You might want to check other threads yourself before stating "facts" like that.
With the final firmware, things seem different, both version are pretty close to each other, sometimes the S600 version wins, sometimes the Octa does.
But most of the time, it seems the Octa has a faster CPU, but the overclocked Adreno 320 in the S600 version of the S4 beats the PowerVR 544MP3 of the Octa version.

Anyways, I'm not basing my info of a single stream on benchmarks conducted by someone after a few firmware updates, that doesn't show anything and certainly doesn't do much towards leveling the playing ground between the two soc's. I've done pretty extensive research into the architectures of mobile chipsets, both Qualcomm and arm designs; mostly reading up on how each generation changes from one to the next and some blue prints. S600, or even s800, based chips will not perform as well as any a15 chip. More efficient? Definitely, but that's about it. In fact the s800 architecture really doesn't deviate that greatly from the dated krait s4.

Hmm, you were the one talking about benchmarks (and how the Octa smothers the SD600 in them), I only gave you a link to one (that should be among the best benchmarks for GPU) that contradicts what you said.
If you want links to other benchmarks showing the same type of results between the 2 SOC, it's not hard to find either, it's not like this is the only benchmark giving these results.
Also, theoretical performance (based on blue prints, and the architecture of the SOCs) is one thing, but it does not always translate to practical performance.
To tell you the truth, I was pretty sure I'd import the i9500, but I'm changing my mind more and more based on what I'm reading.
I'm still not sure right now though
But in real life use and gaming, it shouldn't really make a noticeable difference in performance whether you have one or the other.

Yeah, but truth is that it's still hard to tell which version is better, and it probably won't even make much difference in usage
Battery usage is still unknown too, even though on paper, the Exynos sounds good, it really depends on what you do, and how well the dual processor architecture manages that.

S600 after all ?

Post on Gsmarena:
"The motherboard has a Qualcomm Snapdragon S4 APQ8064-1AA chipset, which as it turns out is a downclocked Snapdragon 600 chipset – four Krait 300 cores (rather than Krait 200) at 1.5Ghz and Adreno 320. There are also four Elpida 512MB RAM chips, SK Hynix 16GB eMMC storage, a Wi-Fi a/b/g/b and BT4.0 capable Qualcomm chip and an Analogix SlimPort transmitter."

It's not exactly a 1.9GHz SD600 (APQ8064T, APQ8064AB) downclocked, but a Krait 300 variant (APQ8064-1AA) that is intended to run at 1.5GHz, so overclocking I'd imagine would come with plenty of throttling and battery consumption.
It really is the perfect HW for current generational need, it's not like we can do pro-grade stuff that needs Core i5 power, so it's best using the stock clock which is well balanced between performance and battery life.

Underclocking doesn't necessarily lead to a better battery life. It depends on the efficiency at the actual frequency. If you underclock, the chip needs less current but needs more time to finish the work load because it is slower. So what matters is total energy consumption: W = U * I * t (Voltage * Current * time). So to save energy, the current has to decrease more than the time increases for a given workload. Also we can see that decreasing the voltage (undervolting) also saves energy (in this case we don't loos calculation speed because the frequencies are untouched)
