Tweaktown : Nvidia Jetson (Tegra K1)

[jdubs03]

A8 is due in ~2 months. Not a direct competitor with Tegra, of course, but it should beat it the TK1 with ease. Cherry Trail might be shown off at IDF in September as well, although it wouldn't be available for another while as you mentioned.

It'll be interesting to see what Qualcomm does, as they're quite behind right now. Samsung's custom Exynos 6 isn't far off either, so Qualcomm's not going to have it easy in the coming year.

Yea the A8 should be quite the SoC, just a shame it can't rightfully be cross-benched against the other SoC's out there. It'll be interesting to see the ST/MT difference compared to Denver, it could be slightly higher, but then again it has the benefit of the extra potential 30% in performance from 28nm to 20nm. Which just shows that Nvidia really produced quite the chip with TK1; quad and dual core.

In regards to Exynos 6/Infinity, I have been disappointed in Samsung since February when they were teasing it yet never showing it off. I don't know if the 5433 is confirmed, but from what I've seen it is 64-bit, but based on Antutu is still slower than TK1-quad. Maybe Samsung was waiting for the node shrink to show off the Infinity to get a double boost with 64-bit.

The other thing I'm wondering about is with Erista, will Nvidia use a quad-core 64-bit implementation, and then a higher performance dual-core like Logan, or just a dual-core follow on from Logan-Denver.

Gonna have to wait for that. Personally I think it will get close GPU wise and exceed TK1 CPU wise.

It's out in time for holiday season... definitely a good thing for Nvidia. CPU performance isn't likely to hold the crown for long, though.

what faster CPU do you see coming on Android for xmass ? A57 is for 2015. Cherry Trail too.

nVidia's Denver core was announced for the end of the year. But i guess products will be released early next year.

Denver should be released earlier than that. The Nexus 9 is likely coming out this year with Android L, so I expect Denver to be out this year, Q4 to be specific.

That's not what I said.

Ayup. And having both the web browsing and gaming battery life figures gives us a pretty good idea of how much power the SoC will draw under that load. Namely, 10.828 hours on a 19.75 Wh battery equates to 1.824W for the entire tablet under 'active idle' conditions while 2.246 hours on that same battery equates to 8.793W for a delta which can be placed entirely upon SoC + memory of 6.97W. So yes, K1 is definitely burning through over 6W on GFXBench 3.0 - sadly I haven't seen figures regarding how active the CPU is in that benchmark so no idea on the CPU/GPU balance in that figure/how much higher it could theoretically go if all four CPU cores were fully loaded.

Either way pretty much as expected - excellent performance with high power usage to match.

sadly my math fails with this
so a peep gets on a bus for a 2hr ride home how much gaming time does he have after a 2hr ride to work[no gaming , no charge] and after a 8 hr day ?

So comparing the graphics on the nvidia shield tablet on this vs x86 tablets on windows and android.

3d mark 1.2 Graphic Score-SOC name-TDP-Product Name
55318 --- i5 4300u ------------ 15w----- Surface Pro 3
53019 --- i5 4200u ------------ 15w----- Surface Pro 2
42842 --- i3 4020y ------------ 11.5w--- Surface Pro 3
36688 --- Tegra K1 2.2 ghz--- ?--------- Nvidia Shield Tablet
27490 --- A10-Micro-6700T ---4.5w----- AMD Mullins Discovery Tablet
19119 --- i5 3317u ------------ 17w+SB-Surface Pro 1
17045 --- Tegra 4 1.9 ghz ----- ?-------- Nvidia Shield Controller
14886 --- Tegra 4 1.9 ghz ----- ?-------- Asus TF 701 T
13370 --- Atom z3745 --------- <4------- Asus MemoPad 7
9488 ---- Atom z3740 --------- <4------- Asus T100

Now on the i3 4020y score, intel limits the graphic max turbo to 850 mhz on the i3, and 1100 mhz on the i5. Since the score perfectly scales with frequency I assuming that the graphics are not throttling.

Intel better come out with something much better, for the k1 is awesome for a passively cooled tablet when it comes to graphics. The surfaces do not really count for they are not passively cooled.

I think those are the lowest scores I've seen for the MiPad. PcPer has a score of ~3300 higher in overall, but physics is ~4700 higher (graphics is ~930 higher). That physics score is way too low.

Anandtech/PcPer/Notebookcheck all have graphics at 36000+, physics at 20000+, and overall at 31000+ for the Shield Tablet.

Any news on any other chinese K1 tablets?

Without ridiculous 4:3 ratio or ridiculous high resolution this time.

Hey I like my ridiculous high resolution, just as long as the price is right, the colors are right, and I can do 4:1 pixels in the game options to trick the tablet into being 1/4 the resolution to increase framerate. (Or other similar options.)

 

[jdubs03]

The slashgear review has the highest numbers I've seen for the TK1 so far.

Having used the ipad 4 and ipad air, and currently using the ipad air a ton, i'd say this comment is ridiculous. 4:3 is perfect for tablet use. I like it quiet a lot.

Widescreen has its place, mainly for bigscreen tv's and monitors. But tablets? 4:3 is awesome.

Remember...before screens started getting huge 4:3 was the standard. 4:3 is the standard format for all newsprint, and it is for a reason. Size. When you pick up a magazine it is 4:3 aspect ratio because it works for the size of the media. Suddenly when you make that same newsprint into 16:9, everything looks awry. It's better because the media format is smaller. When the media (IE SCREEN SIZE) gets larger, thats when widescreen BEGINS to make sense. Widescreen is good for large screens. Not smaller ones.

4:3, IMO, for a 7-9 inch tablet is THE best. It's much better for media consumption, especially reading your kindle books on the ipad or doing whatever else you do. Now i've used 16:10 tablets, and while they're okay, I find myself not liking it nearly as much as 4:3 on the ipad air. Especially for media consumption. It works for the size. Period. Save the 16:9/10 for larger screens.

Besides which. Why are you complaining. The shield tablet is 1920*1200 isn't it? It isn't 4:3. Unless you live in China and plan on buying the Mipad. Everyone else will probably get the shield tablet if they're interested in the K1.

3:2 is a good format for tablets.
but 4:3 is fine, I would take 4:3 over 16:9 easily if it was not mainly for watching videos.

My main use of a tablet is Gaming, Movies/series , Youtube and forum browsing. I have found that the wide format suits me fine.

I also like my framerate and strongly believe that up to 10'' a 720p res is more than enough. Heck 1080p at most.

For me it's a moot effort trying to push a quadrillion pixels in such a tiny space.

I've seen the mipad get choked due to its stupid res, despite the good chip underneath.

Now if we could really set a 4:1 render to screen ratio, that would be ok by me, but still not on 4:3.

Shield II seems nice, but I'd like it Chinese, in order for it to be cheaper and maybe with more storage as well.

Hey you like what you like.

Shield Tablet does not seem to throttle, so power shouldn't be off the charts, even though it's running at 750-850MHz. Mobile Kepler seems like a great architecture, Maxwell should be even better.

In T-Rex, an OpenGL ES application which doesn't even use the K1's full potential, it already throttles from 59 to 46 FPS. How much do you think a game which uses the full feature set (e.g. tessellation) will make it throttle down?

At the end of its battery life it throttles a bit, but not like this.

I don't know.

Now that's just a load of hogswash.

Ignoring Android's poor record on OpenCL for the moment, any ARM Mali 600/700 GPU supports OpenCL 1.2 full profile. TK1 certainly isn't the first mobile SoC to support OpenCL, though I wouldn't be surprised if it was the fastest.

I guess support and implementation can vary widely.:|
