The snapdragon version isn't available in my country, so I will have to buy the exynos (Pretty cheap right now $500 equivalent). The thing is reviews say the snapdragon doesn't lag a bit while exynos is made for a large device.

Is the performance really this bad? I'm not into eons right now by the way.

No its not worth buying the snapdragon version. My s4 is faster than my note...

With HMP enabled there is no comparison between the two, exynos is up to 50% faster and potentially more efficient. With HMP disabled (as things currently are) then qualcomm is the slightly better chip, but I'm not convinced that the difference is enough to prefer one soc over the other...

In short Exynos 5420 is artificially neutered to seem worse than qualcomm, yet -even so- going either way won't make much of a difference...

Do you have any benchmarks to prove your claim of a speed bump of 50 %?

to OP

There are a lot of threads about Exynos vs snapdragon, long story short

Exynos , tad better cpu
Snapdragon tad better gpu

I've had both, ended with exynos , because I didn't need 4g, but needed 32 GB ( in scandinavia 4 G seems to be 16 gb only)
Lag was more or less the same
I felt the battery time on the exynos was a tad better
They felt equally as snappy when they needed to

BUT!!!
App support was a tad better on Snapdragon, ie more apps in the plastore worked with the snapdragon version, a few more games etc... no big deal for me, but still get me ticked of when I noticed a few apps I bought weren't compatible ( yet?!) with the new exynos chip ( but worked with my sammy S3 also exynos chip, older )

Exynos is fine. I've played with both and from a UI and app use perspective you can't tell the difference. Adreno's a bit faster than Mali but no so much as to drastically alter performance. Some games are better optimized for Adreno so depending on your choice of games it could make a difference. As for app compatibility it's more likely the 2,560x1,600 display that's causing the issue not the specific SoC. If there were huge differences between Exynos and S-800 or drastic app performance differences and app compatibility issues it would be all over the N3 forum and it's not.

HMP for 8 cores have not yet released but look at Note 3 Neo, it uses 2 less large cores and it posts the same antutu score as our note, so by adding two more large cores you can expect the score to be about 50% more. As I said that is only true were all 8 cores would be used at the same time and they are not throttled (that is why I said "up to").

Not really. It also has a 267 PPI display which is benefitting its graphics scores in AnTuTu compared to the SGS4

I was more properly referring to CPU scores which are the only ones benefitted from HMP.
I ran a quick AnTuTu (cpu) test to my Exynos 5420 equipped note and here are the results: http://i.imgur.com/zD32DZQ.png

Notice how remarkably similar they are to note neo's cpu score:
http://www.gsmarena.com/showpic.php3?sImg=newsimg/14/01/sgn3n-leak/gsmarena_006.jpg&idNews=7538

Note that note neo has only two large cores which are clocked lower by 10% compared to exynos 5420 and it still posts almost the same score merely by employing the help of the small cores. Now add two large cores more and you'd get 50% more performance, it's simple math really...

Now I'm not saying that it would be a performance that we would actually see in most occasions , it would either be throttled or -even- not supported by most apps but still it's potentially there (which was my point by saying "up to").

What will *definitely* be there if HMP is to be enabled is better battery -though- as it would make more efficient use of the small cores. Since exynos 5422 is also on 28nm yet has HMP enabled leads me to believe that we lack HMP for strategic reasons (so that samsung will sell more exynos 5422 / qualcomm equipped machines)

You can't divorce the impact of display area size and PPI from CPU performance. The GPU doesn't absolve the CPU's role in graphics output. An i3 PC with a killer graphics card will perform worse graphically than an i7 PC with a lesser card because most computational (not rendering, texture mapping, vectoring, and decoding) work is still done on the CPU. So I have no idea what AnTuTu's testing to come up with a CPU rating in isolation but if it's a real-time performance test the CPU's role in graphics output is impacting it. So comparing the Neo with a 5.5" display and 267 PPI against the N10.1-14 with a 10.1" display and 299 PPI isn't going to get you a relevant CPU comparison. That's why I used the N3 and SGS4 as comparisons because only the PPI is off. And the Neo would be well behind the SGS4 in the cumulative AnTuTu test if it had the same PPI because the lower workload of the lower PPI is artificially enhancing its score. At the end of the day an isolated CPU number is pretty meaningless. It's like bench horsepower in a car vs. horsepower to the wheels. A higher bench rating means nothing because none of us drive an engine, we drive a car. The total AnTuTu number (AKA: drive train loss) is more relevant even though it doesn't support the point you're trying to make about HMP.

Maybe so, but the benchmark in question runs off screen. So while in real life resolution matter in Antutu Cpu score, or super pi , or, or, it doesn't. HMP will make the Cpu 50% faster in multi threaded operations, I never claimed it makes the total machine faster by the same amount. For example an HMP equipped note 2014 will score around 40000 in Antutu , NOT 49500. I don't see where we disagree, I merely think you misunderstood my initial claim

If you live for real world use, the Exynos Note is a wonderful tablet. If you live in the world of needing the highest quadrant and antutu scores you should pass.

How did you enable HMP? My note 3 snap dragon is so much faster than my note.

It will never be released for Exynos 5420 either, unless Samsung want alot of complains about fried Exynos 5420 chipsets. Also they already said it wont release HMP for Exynos 5420 cause of the heat.

Once again, that's not the reason that they won't release it, if anything the chip would be cooler because more use of A7 cores would be possible and if all 8 cores are needed Samsung could choose to throttle the thing. The reason that they don't release it is the Exynos 5422 which is the same chip but with all 8 cores enabled (also 28nm)...

So no fried socs, lesser profits more like
