Nexus 9 storms through Geekbench, Tegra K1 outperforms Apple iPhone 6's A8
1. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
I knew the Nexus 9's Nvidia's 64-bit Tegra K1 would out perform Apple's A8. Google is killing it & the rest of the world is on notice!

i'd wait for the A8x first. I doubt any of them will oust the other in day to day use.
10. brrunopt (Posts: 742; Member since: 15 Aug 2013)
because ? we are talking about CPU , not GPU .. (until now AXx versions only had better GPU's )
16. slh163 (Posts: 138; Member since: 19 May 2014)
whaat! say it again.. A8x have better GPU!!
the K1 is known for how great his GPU is with his 192 cores that can even play some consoles games like Serious sam 3 and Trine 2. do you think that A8 or A8X can run these games like K1 do??
22. brrunopt (Posts: 742; Member since: 15 Aug 2013)
I'm talking comparatively to non-x version, not comparing to K1 GPU
- > A6x better GPU than A6 , A5X bettter GPU than A5 ...
24. TylerGrunter (Posts: 1506; Member since: 16 Feb 2012)
I think you just missundestood what brrunopt was saying. He never meant A8x will have better GPUs than Tegra K1.
He only meant that AXx GPUs only have GPU improvemnts over the AX versions, not CPU ones.
EG: A8X will have a better GPU than A8, but the same CPU.
12. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
Did you read the article? They are implying that the A8X based on these numbers might not be able to topple the Tegra K1. This is a BEAST processor. Finally taking the single-core performance away from Apple.
Imagine if this had 4+ GB of RAM instead of 2GB...

A tablet that outperforms a smartphone, good job...
Wait for the comparison with the new iPad before claiming supremacy
53. TechieXP1969 (Posts: 7812; Member since: 25 Sep 2013)
Its still the same hardware whether its in a tablet or phone. The Apple A8 is the phone CPU, the A8X is the tablet version. Same CPU but with a slightly high clock speed...the GPU will liley also be the same but maybe with a slightly higher clock speed. Taking the same chip and making run faster is no big deal.
After all the iPad is just an iPhone without cellular capabilities and a larger display with more pixels. That is why Apple makes the processor slightly better as far as speed. The iPad also has a bigger battery. Increasing the clock, surely increases the drain.

You must be feeling pretty silly right now given how powerful the A8x is.
And yes i made an account just to reply to you.

Your noob is sticking out. You might want to tuck it back in.

I'm also happy to see some real competition in single-core performance. Let me just say this here as well (I mention it in the article): keep in mind that those are preliminary results. The final Nexus 9 should run at 2.3GHz, while the Geekbench score registers it at 2.5GHz, so there might be some slight variation.
13. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
Competition is always good. Apple is already modding the A8 & turning it into the A8X. Imagine what a modded Tegra K1 will do...
25. Iodine (Posts: 1280; Member since: 19 Jun 2014)
If there would be an A8X it will definitelly not be a derrivate of A8, but a SoC developed in paralel with it, there is no "modding" in there.
If we take the A6 and A6X for example, the only part that was the same were CPU cores.
35. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
Thus modding cause they share something. It's NOT a 100% completely different unit.
28. sorcio46 (Posts: 434; Member since: 27 Jul 2011)
Geekbench on Android shows the max frequency read in the kernel, that can be different from the max frequency of the OS.
Or that 2.5GHz is a turbo boost used only by the SoC in single threaded tasks, but in dual core mode it runs @ 2.3GHz
29. TylerGrunter (Posts: 1506; Member since: 16 Feb 2012)
We will see that when it comes, but the preliminary results are promising.
By the way, are you sure Denver is 9-issue or is it a typo?
I always read it is a 6-issue (6-fe wide) core.
Ah, and remember that is is geekbenk for 32bits, so some performance increase is expected when the 64bits version is out (even I doubt it will be more than a 5-8%)
34. RebelwithoutaClue (Posts: 2630; Member since: 05 Apr 2013)
Is the 9-issue related to the number of instructions per cycle it can do? Since the Denver K1 can do 7 instructions per cycle (the Apple A8 6 and Snapdragon 810 can only do 3)
37. TylerGrunter (Posts: 1506; Member since: 16 Feb 2012)
Is related to the number of paths an instruction can take, so how many instructions could be issued "in parallel" (6-issue wide)
So Denver should be 6 or 7 (I read both, 7 at first and later 6), instead of 9. That's why I'm asking if it's a typo or he has more information about the internals of Denver.
The intructions per cyle (IPC) relates to how good the OoO engine is dispatching instructios, not only about how wide the core is.
In other words, the width tells you some "theoretical" maximum IPC under perfect conditions (that are never to be met).
More or less, as I'm not 100% sure about what I'm writting ;D
42. RebelwithoutaClue (Posts: 2630; Member since: 05 Apr 2013)
Than it's 7, since it's a 7 way superscalar cpu :)
Dunno how he came up with 9 though. That would be stellar.
lol I know the feeling, have that all the time lol
64. TylerGrunter (Posts: 1506; Member since: 16 Feb 2012)
Fully on target, it´s seven. I must have mixed it with something else.
I would have been wonderfull to have a 9-wide one though, performance would have gone through the roof!
One word about it: they are not ARM cores, but transmeta, so in reality the performance is about half. Let´s say that is is the equivalent of a 3.5 wide ARM core with 64 bits.
Which taking into perspective that A57 is still 3-issue, 3-dispatch wide is great news.
43. Napalm_3nema (Posts: 2075; Member since: 14 Jun 2013)
6 per cycle for the A7/A8, I thought. I might be wrong.
48. RebelwithoutaClue (Posts: 2630; Member since: 05 Apr 2013)
Yup, the A7/8 has 6 per cycle, double the amount of the standard ArmV8 guidelines.
46. Victor.H (Posts: 632; Member since: 27 May 2011)
Typo! I must have been thinking about the Nexus 9... It's 7.
85. Neo_Huang (Posts: 1067; Member since: 06 Dec 2013)
The XiaoMi MiPad also has a Denver Tegra K1. You may want to test that.
11. masi0 (Posts: 4; Member since: 19 May 2012)
note apple is dual core 1.4ghz CPU - this Chihuahua is mad as pitbull :)
27. brrunopt (Posts: 742; Member since: 15 Aug 2013)
and that means exaclty what ?
until you measure the power consumption of booth you you cant make any assessment about witch one is more power efficient...
45. Napalm_3nema (Posts: 2075; Member since: 14 Jun 2013)
We already know the K1 is not cool running or power efficient. If it was, the Nexus 6 would be 64-bit K1 instead of 32-bit SD805.
59. samub (Posts: 34; Member since: 01 Oct 2014)
it's probably due to gpu , 32bit k1 usese different arch yet it didnt used in a smartphone.
41. Napalm_3nema (Posts: 2075; Member since: 14 Jun 2013)
Don't you mean Nvidia is killing it?
52. InspectorGadget80 (unregistered)
Everyone kills Apple.
69. strudelz100 (Posts: 644; Member since: 20 Aug 2014)
Thank Nvidia for designing the first custom core for Android in 3 years. One that prioritizes single core performance and advanced architecture over just adding cores and clock speed.
64bit ARMv8 is superior in all ways. Most people just don't have the technical chops to understand why. Android's hardware fragmentation is the only reason Android is late to the 64bit party.
70. medicci37 (Posts: 1268; Member since: 19 Nov 2011)
Really? The 8x performs much better. It's sad how little people have come to expect from Google
89. macphisto (Posts: 2; Member since: 02 Apr 2013)
And now the iPad Air 2 is out and the A8X is basically smoking the K1 :)
2. ihavenoname (Posts: 1693; Member since: 18 Aug 2013)
Great job Google/Nvidia. Interesting to see how A8X performs.
5. Chuck007 (Posts: 999; Member since: 02 Mar 2014)
Wonder if A8X will have it beat?
The Nexus 9 is looking to be a real promising product. Hope the Boomsound speakers are dope.
14. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
Boom Sound speakers are SUPER dope. Go to any store that carries a HTC One M8, you will be blown way for sure!
6. darkskoliro (Posts: 1076; Member since: 07 May 2012)
Still waiting for those K1 haters to come out of their cave to troll this article.
15. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
No hate, they would have to be crazy. Numbers don't lie, the Tegra K1 is super!
18. darkskoliro (Posts: 1076; Member since: 07 May 2012)
So much hate. Every article I have commented on K1, people have laughed at how I thought it was beast.
19. SuperAndroidEvo (Posts: 4799; Member since: 15 Apr 2011)
Yeah I hear that, well now those haters are officially shot down! You were right & they will all have to eat their words!
In one word... "BEAST" is the only way to describe the Tegra K1.
20. Iodine (Posts: 1280; Member since: 19 Jun 2014)
Show me the power compustion, if they will be low enough, then I will agree with you that tegra is a "beast".
There is no hate in that.
7. tech2 (Posts: 3326; Member since: 26 Oct 2012)
Benchmark wise Nvidia always performs but its the battery department which it falters rather badly. It'll be more interesting to see what is the battery life of Nexus 9.
Until then I'll rate Samsung's Exynos above K1.
23. gaara6775 (Posts: 738; Member since: 20 May 2014)
Exynos? Seriously? They are not developer friendly at all. Don't know when ppl will understand
54. Napalm_3nema (Posts: 2075; Member since: 14 Jun 2013)
Samsung doesn't have an Exynos. They make it, that's it. It is an ARM design, unlike K1, A7/A8, and Krait cores, which are custom designs. Exynos is just a Samsung brand name. Mali is stock ARM GPU, as well.
58. xfire99 (Posts: 776; Member since: 14 Mar 2012)
The new 64-bits Exynos 7 SoC said to be Samungs own custom design. Just wait until it release and see if its right.
60. samub (Posts: 34; Member since: 01 Oct 2014)
they already renamed exynos 5433 as octa 7 ,samsung never used custom design on exynos chip , i doubt they will made it.
62. renz4 (Posts: 317; Member since: 10 Aug 2013)
so far exynoss 7 seems to be some kind of rebrand of current 5433. so it will use A57/A53 for sure.
(check 6th paragraph)
also creating custom design is not easy and the license cost are much more expensive.
78. strudelz100 (Posts: 644; Member since: 20 Aug 2014)
And that's why the resulting cores perform MUCH better.
Krait is a 3 year old custom core. Most people using any flagship device are using very old custom cores.
It's time for a new one.
9. samub (Posts: 34; Member since: 01 Oct 2014)
omg , browser.primatelabs.com/geekbench3/search?utf8=%E2%9C%93&q=htc+volantis
this scores even in 32 bit mode ,when geekbench updated it will easily exceed 2000 point.
17. promise7 (Posts: 854; Member since: 03 Jul 2013)
Comparing a tablet to a smartphone? Seems fair.
21. WallStreetWolf (Posts: 289; Member since: 08 Apr 2013)
I think I'm going to wait till I see battery performance before I go crazy about CPU performance. I think it does a great job, but real world use is the only thing I care about.
26. gaara6775 (Posts: 738; Member since: 20 May 2014)
I'm happy to see something beats iphones in single core geekbench mark. And I'm glad its nvidia.
31. medicci37 (Posts: 1268; Member since: 19 Nov 2011)
When adjusted to account for the clock speed difference between the 2.5 version tested on geekbench & the 2.3 version on the Nexus 9 there won't be much of a difference compared to the new iPhone & ipad.
32. supraguy88 (Posts: 5; Member since: 13 Aug 2013)
Just ran my Exynos 5433 Note 4 on Geekbench for the first time and got 4075 on the multicore test! :-)
44. j2001m (Posts: 2755; Member since: 28 Apr 2014)
and it as 8 or 4 cores, the t1 as 2, it f...s all over the note 4
57. Awalker (Posts: 1363; Member since: 15 Aug 2013)
The 8 core version only runs 4 cores at a time. There's only one true octocore processor (all 8 cores running at the same time) out there and it's produce by Mediatek.
