That's performance... now where is energy consumption? I'd like to know if A57 is A15 2.0.



Why doesn't everyone use Moorefield? It's built on the most advanced process. It has an impressive energy consumption. They don't have a Qualcomm-like monopoly; which sucks money out of every 3G (and presumably 4G) patent. Intel has a compelling roadmap and commitment to Atom: they have LTE, they have some of the best architects and a 2 year Tick-Tock cadence, it is built on the most used architecture, and Intel has a massive process lead.

I don't think Broxton will change everything, like you envisioned 1 year ago. Intel really has to deliver next week.

id really love to get BK into a room and get answers to these very questions. the company has the best process, has billions and billions of r&D resources and accumulated knowledge and its really not gotten where it should be - yet - in mobile.

cherrytrail is nowhere to be found. broxton i havent heard anything on in ages.

What would be A15 2.0 in your mind?
Low performance/watt; high power consumption. Don't faint:



Being technically the best (and even that has to be proved) is not enough.
Isn't "being technically the best" not what determines the review score of CPUs (after taking into consideration the price, which I don't expect to be a problem)?

At least they don't suffer financially...

ntel (NASDAQ:INTC) has been losing a billion dollars per quarter on the mobile segment of its business. Ugly is a severe understatement for this loss. Four billion dollars per year in losses. That's about the combined sales of Xilinx (NASDAQ:XLNX) and Altera (NASDAQ:ALTR).

What I find amazing is that Intel can drag this enormous boat anchor behind them and still generate 65% gross margins and 23% net margin. If the two companies mentioned above were to run losses like this, their net tangible assets would be depleted in a year and a half and they would be bankrupt. Intel, on the other hand, absorbs the losses, spends $11 billion a year on capital improvements, $4-12 billion on share buybacks and pays shareholders $4.5 billion in dividends.
Although it'd be better if they cut the share buybacks and dividends and invest the saved money in process nodes (and yields) etc.

cherrytrail is nowhere to be found.
Wasn't it a nice time in 2013 when we still though they'd start HVM production in Q4'13 and we'd see loads of products, CT, Moorefield and Broadwell, in Q3, followed by Willow Trail and SoFIA in Q4.

You'll hear about it next week.

I thought you were talking about the micro-architecture itself. Good question about the power consumption, and one I'd like to get answer for too!

You were asking why despite being the best it doesn't get design wins. This has nothing to do with reviews or benchmarks scores or whatever. Either Moorefield is much poorer than what has been shown or makers just don't want to invest in a platform where there's a single provider.

I think a high BoM, lack of modem integration (XMM 7260 has barely gotten certified on the major carriers to my knowledge) and perhaps sub-par ISP performance is what kept Moorefield out of the running for phones.

Moorefield is very much like AMD's Mullins; it benchmarks well, and there are a ton of conspiracy theories around why it isn't being used, but the truth is, these OEMs aren't stupid and if they're not using Moorefield there's probably good cost/technical reasons for them to not.

Will Intel announce that the contra-revenue gets another round, this time in the smartphone space, or will they just set a 40M smartphone goal for 2015?

No, SoFIA is designed to not have contra-revenue.

I wouldn't be surprised if they price SoFIA aggressively in the low-end and mid-range of the smartphone market. SoFIA, IMO, looks good enough to actually win some decent low-end with the 3G version and perhaps mid-range spots with the LTE variant.

I think if Intel can become a 5% market share player next year (about 60 million units), that'd be a good start.

It's amazing how every post on mobile SOCs is infected and hijacked by this intel troll. This thread is about Note 4 running Exynos, not Intel moorefield, or crystalwell or broxton or any other SoC from that massive failure in mobile. Get it? Please go and start a new thread crying about why no one is using Intel SoCs.

Stop crying. and trolling. Please...

Get your facts straight, please. The thread was, as you call it, "infected and hijacked" not by me but by "Intel troll" Intel17:

Moorefield in the 4.5" FFRD scores 21752

Too bad Intel didn't actually get that part into phones...

Also, I'll refer to Homeles' great post:

Yes, we know how badly the AMD-enthused like to suppress any talk about Intel, and vice-versa. Shame we can't grow up and get along.

Instead, we're punished for having a conversation -- for having a discussion. This all happening in a forum, which quite literally is a place to discuss things.

Asinine, all of it.

Instead of, you know, reading the damn thread, and trying to understand the context behind what and why people are saying what they are, we get some smartass quip about from someone who clearly failed to do either -- someone who is clearly disinterested with and biased against the current topic of conversation.

It's so dumb that online forums in general are so unidirectional. There's this moronic preconception that all conversations are static, and everyone must stay on topic, or they're a sinning rulebreaker.

Then a moderator comes in and enforces these ridiculous misconceptions, and the conversation dies. Learning ceases.

I don't know what world you guys live in, but when people converse here on Earth -- be it in person, or on the internet -- the topics change.

Discussions are dynamic. Get over it.

By the way, most topics I react in are about Intel..

Now that's interesting.

Samsung lawsuit claims that NVIDIA's benchmarks are misleading

Samsung definitely isn't taking NVIDIA's first patent lawsuit lying down. The Korean tech firm has countersued NVIDIA not just for allegedly infringing on six patents, but for leading buyers astray with benchmarks for the Shield Tablet. NVIDIA is supposedly trying to "confuse customers" by claiming that the slate's Tegra K1 processor outpaces the Exynos 5433 chip in the Galaxy Note 4; regular benchmarks show that's not true, Samsung claims. The suit also accuses PC vendor Velocity Micro of violating two additional patents (for a total of eight), since NVIDIA's graphics cards play a heavy role in its lineup.

NVIDIA tells Engadget that it's still examining the complaint, but it's already rejecting allegations that it misled gamers with its Shield tests. Both devices were using their stock, fresh-from-the-box software loadouts, the company insists. Whether or not that's true, the lawsuit comes across as the pot calling the kettle black. After all, it was the revelation that Samsung inflated benchmark scores which led many to question the honesty of mobile device makers. Really, the assertion of dodgy benchmarking is as much about corporate pride as anything else -- if successful, it would force NVIDIA to eat humble pie.

Geekbench is now being used in high profile lawsuits to dispute performance claims! If I were jfpoole, I'd be feeling pretty proud right now

That said, I wish it were easier to test "real world" performance for mobile devices rather than just synthetics. If you look at an AT PC chip review, most of the benchmarks are actual real applications that people care about with a few synthetics thrown in that few care about.

The "hijacking" of this discussion was indeed my fault. Although I thought benchmarks of competing chips would be useful in creating a discussion that we could all benefit from and learn from, I also recognize that some people would prefer to stay strictly on topic. I'm cool with that and apologize.

Your data point was definitely interesting and IMHO on-topic. I also agree with Witeken and Homeles that staying strictly on-topic is unnatural and in fact counter-productive, at least as long as we get back to the topic being initially discussed

Now Samsung will have to explain why they change power profile when detecting some applications :whiste: That's a really stupid lawsuit, every company shows benchmarks that favors their products, and even cheat producing the numbers.

More benchmarks.
Note that Exynos 5 Octa 5422 is basically 4x A15 @ 1.9GHz + 4x A7 1.3GHz, same clockspeed and number of cores as Exynos 7 Octa 5433 but based on ARM's older architectures.

CF-Bench

Exynos 5433



Exynos 5422



Exynos 5422 vs Exynos 5433: A15/A7 vs A57/A53 @ same clocks.

In fairness to Samsung, they stopped doing this on their products this year. Unfortunately other OEMs, especially Chinese OEMs, continue to do so.

The Shield tablet Antutu score you linked to is using an older version of the benchmark. In version 5 of Antutu, Shield tablet scores ~ 56,000:



In Geekbench 3, using "max performance" settings, the Exynos 7 Octa is using all eight cores to obtain that multi-core score, which is completely unrealistic for any real-world application.

On a side note, Shield tablet has very little CPU/GPU long-term performance throttling too due to the internal magnesium shield, so it can maintain the performance too.

Why? It might drain battery faster and I'm not sure how long it could sustain all 8 cores at high clocks but some apps might benefit from this capability. Also Cortex A57 @ 1.9GHz seems to beat Cortex A15 @ 2.2GHz in the single-core score.

Are you sure it's using all 8 cores in Geekbench? MT score seems to be in line with the ST score for a quad-core part - 3.15x scaling for Tegra K1 and 3.4x for Exynos 7 Octa.

No need to get defensive, as I said, many companies would do/do the same to make their products looks better (Samsung included).

Well they claimed to have measured at the default optimized settings, and running with all eight cores active is most certainly not that. And if one looks at a wide variety of GPU, CPU, and browser benchmarks, Shield tablet clearly outperforms Galaxy Note 4 most of the time, which is the point they are trying to make.

FWIW, now that A8X just came out, NVIDIA is no longer promoting Tegra K1 as the world's fastest mobile processor (although Tegra K1 still does lead A8X in 3dmark Ice Storm Unlimited Graphics and Physics benchmarks, and 64-bit TK1 leads in single-threaded Geekbench 3 and Kraken performance too).

I never changed any setting @ Geekbench or any other benchmark, 100% default settings. I'd actually like to test with 4x Cortex A57 cores active instead of A57+A53 now for comparison purposes, I'll check if that's possible.

And if one looks at a wide variety of GPU, CPU, and browser benchmarks, Shield tablet clearly outperforms Galaxy Note 4 most of the time, which is the point they are trying to make.

Shield's GPU is undoubtely faster, but I'm not sure if 4x Cortex A15 cores @ 2.2GHz outperform 4x Cortex A57 cores @ 1.9GHz + 4x Cortex A53 cores @ 1.3GHz most of the time.
