Samsung Galaxy S II Skyrocket benchmark tests

Samsung Galaxy S II Skyrocket benchmark tests
It wouldn’t surprise us if there are still some people out there crying over the Samsung Galaxy S II Skyrocket’s choice of using Qualcomm’s processor as opposed to the dual-core Exynos CPU from before. Thankfully, its 1.5GHz dual-core Qualcomm Snapdragon S3 processor seems speedy enough on paper to deliver an experience that’s top notch in terms of control, execution, and stability.  But will it take a commanding presence like the original version?

Out of the box, it’s nearly impossible to meticulously find any difference in performance between the Skyrocket and AT&T’s version of the Samsung Galaxy S II – since they’re very responsive with their operations. Exuding some slick movement while navigating across its homescreens, it doesn’t seem tested that much when we activate a graphically intensive live wallpaper. In fact, everything appears to be fine and dandy with the handset – so it’s still a quality device based on its initial performance out of the box. However, we do notice that it’s only a notch down from the performance that’s exhibited by the AT&T Samsung Galaxy S II – though, it’s negligible.

Before running any benchmark tests, our mind tells us that it’ll probably be slightly below the level of its Exynos equipped counterpart. Rather, we’re pleased to find it performing on the same level, since we’ve able to get scores between 2,787 and 3,636 with the Quadrant benchmark, which is clearly on par to the AT&T and T-Mobile versions of the Samsung Galaxy S II. Moving on with the AnuTu benchmark test, it’s given an overall admirable score of 5,752. Needless to say, it’s well up there in terms of performance – riding close to other devices like the international version of the Samsung Galaxy S II and even the Galaxy Nexus.

So what does it all mean? Well, even though it’s not sporting that lovable Exynos processor from before, it’s not sacrificing on performance with its Qualcomm Snapdragon processor. Instead, it’s delivering a spot-on responsive performance out of the box, which is what we’d expect with this juggernaut of a smartphone.

Am I the ONLY one that can make the easy assumption that Samsung has found a way to fidget with score numbers? NO HTC phone running the EXACT same hardware configuration comes anywhere close? Is it magic? No.. its fidgeting with benchmark tests somehow... Otherwise, you would see the HTC Amaze get the same scores, and the Vivid and sensation get really close scores. Thats not happening, its ONLY samsung getting these kinda scores with this setup. Its being FAKED. And this is coming from the guy that normally champions samsung phones.

As in the phones are like programmed to give a false reading? If this comes from anyone else, I would laugh at that. Do you really think Samsung would risk that in the face of all the legal challenges it is facing?

there wouldnt be any legal challenges... its not a big enough issue. I know from past experience that the I/O score is easy to manipulate. The only way to really tell is to use the paid version of quadrant as it will break down each category and give you its individual score as well as the total score. Take that individual score and compare it to the Amaze and other Dual Core Snapdragon S3 phones with similar set ups. Id bet money that the I/O score has been manipulated and is higher on the Samsung hercules/skyrocket. EDIT: That is EXACTLY what samsung did. Here is the Antutu benchmarks from the Amaze which runs the exact same 1.5ghz and 1gig ram set up as the Hercules/skyrocket. That gray part of the benchmark IS THE I/O score (Antutu calls it CPU Intiger). Compare that screen shot to this phone's and you easily see the huge increase in the I/O marks. I love some samsung hardware, but I will call out dirty pool wherever I see it.

Wow... I knew it...

Best part is, if your breaking it down by score, the I/O score is the least useful part of the chip at this point. The chips are too powerful, they all score well in I/O. If you want to know what chip is best look at the 2D/3D power, floating point, ram, database access, and SD READ... Basically everything but the I/0 (integer) and the SD Write. I wish the OMAP processor was in there for a more accurate portrayal of the big 4 chips.. but oh well.. for reference it falls between the tegra2 and the exynos. the snapdragon unaltered falls behind the pack.

You are right, I have the paid version of qradrant, and Tmo-GS2 actually scores lower than Sensation XE in every categories except the I/O. Its I/O is way ahead of the the XE and the total score of the GS2 was ~3500s, and the XE was ~2600.

Ok from comparing the score between the HTC Amaze 4g and the Samsung Skyrocket i've come to this conclusion. Correct me if im wrong because im no phone whiz. HTC Amaze 4g: Ram: 453 CPU integer: 1238 CPU float-point: 423 Samsung Skyrocket: Ram: 878 CPU integer: 1952 CPU float-point: 772 It seems to me that the more ram is available for use the higher it can score for cpu integer and cpu float-point. As we know HTC sense is a major ram hog and Samsung TouchWiz is pretty light on ram usuage. Anyone with with an HTC Amaze will find usally you have only 300-400 ram available for use. With Samsung Galaxy S2 phone you can get about 700-800 available ram. So maybe this is why Samsung phones with the same Snapdragon s3 chip while always score higher than HTC phones

for over all system function sure, but the CPU I/O(intiger) is a baseline test. It isnt affected by the software. Its a test that is basically measuring how fast the chip can calculate answers... say to PI for example. As to why this test in particular is the one that is so easy to manipulate, that is beyond even my pay grade, but it is the test that people use to cheat and buffer over all scores on. Ram may or may not make a difference, but that is why I chose to compare it to the Amaze.. they run with the same amount of total ram and same chip configuration. The sensation however gets similar scores to the amaze and it has a good chunk LESS ram than the amaze does as well as the lower 1.2ghz clock. Like I said in a previous post, this benchmark for I/O is nearly useless now exept for baseline bragging rights in super computers.. lol. Computer chips are just so fast now that we cant throw enough at em to make a real world difference for 99% of us. If your not into tech, this wiki blurb might make your head spin, but its a good discription of I/O and floating point scores.

I dont know how to post pics but here's the results: GSII: Total: 3969 CPU: 6786 Mem: 2970 I/O: 8621 2D: 407 3D: 1059 Sensation XE: Total: 2720 CPU: 7112 Mem: 2231 I/O: 2993 2D: 327 3D: 935 Also note that the scores of the GS2 are very unstable with ~2500-3900, while the XE are quite stable with ~2500-2800

what's wrong with that? I think it's probably the Sense UI that bogs down performance of HTC phones. Sense is notorious resource hog. But it seems Sammy did pretty good job on the new TW 4.0 to get those scores with better file I/O and hardware acceleration.

C'mon man... are you serious? You still cannot accept that the phone and processor are much better than you thought? You're provided with PROOF and you're still making excuses. "Samsung faked it." Ok, so they would fake this benchmark to look on par with the Exynos but not fake the Exynos to look even more powerful? ACCEPT IT... IT'S A GOOD PHONE! As for your HTC comparisson, maybe it's not just the processor. Maybe it's the whole package, the way all the components interact with the processor. Maybe Samsung knows how to squeeze more juice out of it then HTC. Maybe Qualcomm stepped up their game. Whatever the reason.... you bash the phone/processor and even when you're provided with proof you cry conspiracy. Think about what you're saying and how it sounds.

concidering i provided an educated opinion, proof to back up my claims and worries, and people that know about chips agree with me that its probably messed with... id say I'd sound like an individual that has done his homework and has a valid concern.... not someone who is screaming it must be true on a bunch of "maybes".

Are you entirely sure that the IO result comes ONLY from the CPU? Well, what really differs in OCZ Vertex 3 and V3 Max IOPS is the MEMORY (being synchronous vs. asynchronous), not the CPU. And likely firmware optimisation. And the firmware between HDDs for Servers and others. So more and better ram - more IPS. It's very likely that Samsung knows better than HTC how to use memory... In truth I've thinking about the same issue - that Samsung could have manipulated the score, but if that was the case someone would have been done enough research @ XDA to make some noise. After all most of the androids is open source, aside of some hw drivers.

The I/O test itself is a CPU test that (and i explained this in another post) basically measures how fast it can come up with answers to an equation... like say, the first 500 digits to PI. Since its basically a FLOP test (how fast the internal "on/ off switches" can move) Im not sure if its affected by RAM or not. the I/O is a measure of MFLOPS on the cell phone scale.. Super computers go to PetaFLOPS and beyond, just as a reference.

I think you are mixing up the the things. First thing "I/O" is related to hdd, ssd, flash memory ... So CPU I/O is not the same with CPU Integer performance. CPU's have separate integer and floating point units, and with that how in the he** CPU Integer performance can be expressed with FLOPS (floating-point operations per second). Read-up little bit, because you are confusing the people. "I/O" != CPU INTEGER != CPU FLOPS

I/O simply means input/output. input the command, output the answer. As in how fast the CPU can take the equation and spit out the answer. That is all. it is related to anything that can take in info and spit it out, which most definitely includes a CPU.. on a PC or smartphone. The integer test IS an I/O test. throw integers at the CPU, and measure how fast it spits out the answer.

"I/O" != CPU INTEGER != CPU FLOPS CPU Integer IS NOT measured in FLOPS as you stated above ... I'm out ...

I've suspected it for weeks. Samsung's the only manufacturer that fiddles with the file system, cept it was giving low scores on the galaxy S devices, they must've switched tactics this time. And they do the same thing with the Tegra II in the Galaxy R I imagine.

The benchmarking community calls the SGS2 an "anomaly". Nobody knows why or how it does this & there is suspicion that somehow the numbers are simply not true. Nobody knows "for sure" what is going on but it certainly doesn't make sense; even to "experts" in bench-marking it's strange.

dont mean to disrespect you sir but samsung is way better than anybody on the market right now.. lets accept it. nothing is being faked. lets see what they achieve with sgs III

I Agree, nothing compares. I find myself comparing Samsung to everything else all the time, and Samsung always wins.

Zeus, You are not going to find a bigger champion of Samsung's tech on this site than me. I would also be part of that elite group of technophiles that has in depth knowledge of the chips in question. The other 2 guys would be King Korugi (AKA Thump3r) and Protoloz. This chipset is not capable of this performance. However I refuse to close my eyes to the competition or to the company who's products I buy. Blind fanaticism only gets you slapped by the direction that you close your eyes in. A spade is a spade is a spade.. no matter who carries the spade. And in this particular stance, Samsung is playing dirty pool. The proof is right in front of you for all to see.

have you heard of resolution? and how they affect benchmarks ? or the truth that galaxy software is smoother than htc ? sorry but your post sound retarded! why a big company would risk their reputation for a benchmark test! you have to prove it here or in xda-developers or stfu :) btw there is a way to cheat in benchmarks you can look for it in xda-developers ..

so does that mean there is also something strange about nexus benchmark ... since its the closest score to sgs2 ?

36. remixfa

Posts: 14605; Member since: Dec 19, 2008

no. The nexus uses the OMAP chip which is the 2nd strongest chip next to the exynos. The nexus is also running ICS which is the first android OS optimized to actually USE dual core chips. Until now, android has not taken one bit of advantage of all that processor power. its only been used in games and such like that. As the other phones make their transition to ICS like the nexus has, all their scores will go UP because of this. Thats when we will REALLY see the difference in the chips even more so than we see now... because they will be fully optimized. They are barely being used at the moment.

where do you read that ICS supports dual core ? I didn't hear them saying anything about it at the conference. and SGSII is optimized by Samsung software engineers to use the dual cores .. maybe not as it should be .. but the dual core in GSII are in use

68. remixfa

Dual Core optimization was the first thing we ever learned about ICS. Its built off of Honeycomb, which itself is dual core optimized (just not done At the conference they hit many of the OS highlights and didnt get into a lot of the geekery. There is an article from Michael from a week or 2 ago talking about all the ICS stuff that they didnt mention during the conference. SGS2 can not be optimized by samsung to use dual core in the android OS unless the andriod OS allows it by having system drivers to run it. Which as of right now, no android OS other than honeycomb and ICS has that feature. Its optimized for 3D performance, battery, and a billion other things, but they can not force Android itself to be dual core optimized until Google puts that feature into android... which they are with ICS.
