Qualcomm CMO disses NVIDIA: 'we clean Tegra 4′s clock'

Actually I dislike both when they always try to exaggerate themselves.
"benchmarks published by Anantech, S4 Pro is twice as fast than the fastest Tegra processor"
I don't know what did he mean about the benchmark? Maybe from the buggy Linpack benchmark leading to ~600 points multi thread (which after that proven to be wrong). Or maybe he mentioned about GPU, but clearly he said about "processor", not GPU.

Wasn't Tegra 4 also able to render 4K content? I thought that was one of the main points of Project Shield.

Nvidia made their own LTE chip that is optional with the Tegra 4.

The main reasons why non-Qualcomm AP couldn't work with LTE modem back in 2011 was that qualcomm intentionally made their LTE modem chip work with only snapdragon for smart-phone. It had to couple with snapdragon in order to enable voice/text. This issue is addressed by their new MDM9515 and later 28nm 3G/LTE chip that go in phones like iPhone5, Note 2, DNA, etc.

I think Qualcomm did this to give advantage to their AP back then. But after that, their two big customers (Apple, Samsung) pressured them to make it compatible with non-snapdragon APs for their phones. So now Qualcomm LTE modem should be able to work with Tegra4 too.

Intel is expert in what? I know their Desktop processors are great, outperforms AMD year after year (and I still prefer to buy amd processors, btw). But their motherboard sucks hard, and their onboard graphics... oh god, why? Their atom processors are getting in the right way, but is not what S4 Pro is, atm.

Qualcomm claimed about half the power consumption with the S800 compared to the S4 chips out right now. I don't know how, I just know that they said it.

..yet there's not a drop of doubt that this " idiot " knows far and beyond more about chips than you will ever know.
Do the math now.

In my view, the key categories in choosing a phone chip are:
- performance
- power consumption
- price

According to claims, these new ARM based chips are, amazingly enough, MUCH more power efficient than the current generation, yet outperforming them from 75-150% at the same time.

Intel's new architecture should come somewhat close in terms of power consumption to the CURRENT ARM chips (~5W vs 2-8W)
In terms of performance, they should be about on par, given that low end core i5 are scoring around 5000 on geekbench

..just to clarify.
Intel's upcoming chips should be on par in terms of performance with the ARM based chips such as Snapdragon 800 or Exynos octa.
In terms of efficiency and price, ARM should still hold a clear edge

I bet Intel's regretting selling off their ARM business to Marvell all those years ago.

It would be interesting to see what Chandresekher would say about Intel's competition in the market, considering he's an ex-Intel VP.

and it's even more obvious that you're blindly supporting something you don't have the slightest clue about.

Here's an article by your famed AnandTech that highlights the true potential of 22nm based processors

Oh look who's talking.

YOU have no slightest idea on what you talk about if you think this kind of processor will be in phones this year.
LMAO.
Here's a reality check:

http://www.anandtech.com/show/6695/microsoft-surface-pro-review/9

..now keep in mind that surface pro has about TWICE bigger battery than average 10 inch ARM tablet.
Yet it still has HALF or less battery life.
This means the power draw is around 200% greater than current ARM solutions, and 300% greater than that of the upcoming chips.
Use your brain, if you have any.

My point, don't expect anything close to this kind of specific(suited to x86 arcitecture anyway) performance in a phone this year.

Raw performance could go relatively close though, considering the surface pro scores about 5700 on GB.
I expect the best ARM chips to cross 4000 this year.

You're confusing raw and specific performance.
My phone is trumped in Java script tests against a given entry level laptop - but in overall processing power it actually beats it

The Exynos is not even a real 8 core. You have 4 A15 and 4 A7. Only 4 of the core can work at a time. Man marketing has gotten to you. The T4 has 4 A15 core too.

36. sats.mine2k4 posted on 06 Feb 2013, 10:35 0 1

Agree am no expert in stuff but Question for you: Tegra3 is a quad core A9 and Exynos 4412 is a quadcore built on the same A9 why is the performance like night and day...?

37. ngo2dd posted on 06 Feb 2013, 10:46 1 0

The T3 has a different GPU. The Exynos 4412 has a better GPU. Also Samsung software is optimized for using 4412. It is the same as how tegra zone game look so good. Software will work wonders on a processor if it is optimized.

It's not a marketing gimmick...it's big little architecture...this will result in less power consumption....

43. ngo2dd posted on 06 Feb 2013, 12:57 0 0

But why call it a octa core when it is a two quad core. Do we call the T3 a pentra core processor? No we don't it is marketing gimmick.

He works for Qualcomm, so what do you expect him to say? T4 is already here, but Snapdragon 600, 800 won't come until Q3 this year.

39. kikax posted on 06 Feb 2013, 11:14 0 0

Texas Instruments made better processors than NVidia, shown by the benchmarks. A dual core TI at 1.2 GHz outperformed Tegra 3 1.3 GHz quad. Mali 400 is more tegra optimized than tegra, and has a significantly higher quality shaders. Just so you know.

44. Berzerk000 posted on 06 Feb 2013, 13:03 0 0

Qualcomm said that the S800 will have half the power consumption from current S4 chips, so no need to worry.

47. Captain_Doug posted on 06 Feb 2013, 18:02 0 0

They say that but I remain weary. Regardless, getting as much battery life as possible is my goal. I'll underclock until it starts freaking out then push it back up a couple hundred mhz to be safe.

54. Berzerk000 posted on 07 Feb 2013, 00:56 0 0

But at least they made a statement about it, so we know battery won't be any worse than their current chips which are pretty efficient to begin with; according to them it should be better, though I know that 50% power statement won't be true in retail devices, it'll be closer to 20%.

I'm sure you won't have any problems with underclocking, the current S4 Pro can be set to about 1-1.2 GHz and still be just as smooth as it was on 1.5 GHz just because of how powerful it is.

Good to know. I agree with your estimate about them maybe talking up the efficiency too at least a little. That is a huge jump for not going down in either the manufacturing process or gong up to the next architecture. I can believe that they have improved it though, just not by 50%.

That 50% is probably based on optimal conditions with a certain software setup, like their reference devices they had on display at CES.

They might have changed the architecture around a bit for more power efficiency at higher clocks, I don't really know though. I haven't seen any specifications on the Krait 400 architecture, or how it's different from the Krait used in the S4, but something must have changed to get 20-30% more efficiency with about 50% higher clock speeds and 75% higher performance.

Qualcomm does tend to make minor improvements as they go but yeah, 50% is quite the leap. I haven't seen anything on the Krait 400 either. I'm gonna go a-hunting.

In order to get a Exynos CPU or Mali GPU, you are pretty restricted in buying a Samsung which I don't plan on doing anytime soon. Would much rather have the X-phone with Snapdragon 800.

52. JWS65 posted on 06 Feb 2013, 21:18 0 0

Snapdragon 800 is going to sample in Q2. So it won't be until late Q3 to see it in any smart-phone. My guess is X phone will have S4 Pro or Tegra4.

58. Captain_Doug posted on 07 Feb 2013, 09:55 0 0

That's a little disappointing but the S4 pro is very capable and the Tegra 4 is more than very capable. No complaints here.

Where did you see that? On Qualcomm's own website they say that both the 600 and 800 are sampling now, the 600 should be on the market by Q2, and the 800 should be available in smartphones by mid-year; which gives hope that the 600 or 800 would be in the X phone since it's supposed to be announced in May and be released in June or July.

Qualcomm also said that the Adreno 330 should bring 2 times better performance than the Adreno 320, not 30-40%. I know double the performance is a bit of a stretch, but surely they aren't off by 60-70%.

Why would Samsung use the 600 or 800 for alternate versions of the GS4? The only reason Samsung traded Exynos for Snapdragon in the past was because of LTE problems, but Samsung has that all figured out now.

He didn't "avoid" Exynos chips, it's just Exynos wasn't brought up in the interview. I'm sure if the one giving the interview would've questioned him about the Exynos Octa, he would have given his opinion on it.

64. JWS65 posted on 11 Feb 2013, 12:04 0 0

Qualcomm doesn't have any manufacturing at all. They just have TSMC produce almost of all of their chips. One thing forgotten here is that Apple is trying shift their AP manufacturing to TSMC from Samsung too. This will cause trouble for producing enough Apple and Qualcomm chips. Samsung on the other hand will have more capacity to produce Exynos due to Apple leaving them.
