[AnandTech] Atom Z3770's Cinebench performance

[mavere]

this Baytrail SKU delivers similar performance to a mid-2GHz mobile Penryn based Core 2 Duo. Let that sink in for a moment - this tablet SoC delivers better multithreaded FP performance than a 2010 Macbook Air. The quad-core Silvermont vs. dual-core Penryn comparisons are a little unfair as there tends to be no replacement for extra cores in these thread heavy benchmarks. If Intel is able to equal a Core 2 Duo's single threaded performance however...

I actually have one of those "mid-2GHz mobile Penryns" he referred too.

In the now-closed discussion/soapbox on the Z3770's score in (mostly single-threaded) Kraken, I roughly estimated that its performance there is ~2/3 of my notebook. Comparing that to the current Cinebench results suggests that the Z3770's scaling in multithreaded situations can be close to ideal.

Of course, power consumption versus ARM is still an unknown. For my own needs, though, x86 support is so key that relative efficiency can be "merely" good instead of exceptional.

I highly doubt its actually running at only 1.47ghz myself, if this actually has similar IPC to Jaguar, ARM is going to be in for a bad time. Even assuming a small turbo boost, this is still a very impressive showing from Intel.

Ok. This Baytrail marketting mumbo-jumbo is going for way too long and it's boring and annoying.

When exactly it is out, so I can read normal confirmed in-depth performance, power consumption, etc reviews?


btw.

It's interesting to note that the test system (likely a tablet) seems to be running a 32-bit version of Windows. As there are no connected standby enabled versions of 64-bit Windows, that's likely why we're seeing the 32-bit version used here.

Wtf is this s..? Seriously Intel?

A 2W SDP (3-5W TDP?) tablet CPU (4C/4T 1.46-2.4GHz) Atom Z3770 matching 15W TDP A4 5000 (4C/4T @ 1.6GHz) at CB11.5 MT. Now thats impressive. If this chip is running @ lower than 2GHz with its 4 cores fully loaded then Silvermont could be closer to Jaguar IPC than I though/expected.

Regardless it's probably safe to assume a single threaded Cinebench 11.5 score somewhere north of a 1.5GHz Jaguar.

Quite possibly better single-thread performance than the A4 5000 (one active core should run much closer to max Turbo Boost - 2.4GHz).

Intel has said it will be 50-60% faster than Clover Trail. Best case single thread, it is 2x peak vs the current Z2680. That means twice as fast at 2.4 GHz turbo vs 2.0 GHz, best case. 2.8x is given as best case for multithread.

Look at the AT review of the A4-5000

Now add 10% to that Z2760 and double it for single thread and multiply by 2.8x for multithread. Look at how close they are, by Intels own numbers which we can take for a fact as being best case.

So there you have it quite clearly. Intels fastest Silvermont will perform very closely to AMD's 2nd or 3rd fastest Jaguar.

 

[Sweepr]

Intel's fastest Silvermont-based chip is Avoton/Rangeley, an 8-core server CPU with 20W TDP. The fastest desktop chip will be the 10W TDP Pentium J2850 and it will certainly be faster than tablet's Z3770 (four cores running at 1.46 nominal clock / 2.4GHz max turbo vs four cores running at 2.4GHz nominal clock).

 

[SiliconWars]

Read that as "Bay Trail T".

@seitur - I am guessing review shud be out after its usually announced at IDF sep 12, just like haswell launch

I highly doubt its actually running at only 1.47ghz myself, if this actually has similar IPC to Jaguar, ARM is going to be in for a bad time. Even assuming a small turbo boost, this is still a very impressive showing from Intel.

Not to mention that cinebench is FP and Atom generally is much better at integer loads. AFAIK even silvermont isn't fully OoO in FP but I might be wrong.

Of course TDP can't be compared to AMD A4 because baytrail-t GPU is worse and hence will use a lot less power.

1.47 is the base clock for Z3770, 2.2 or 2.4 is turbo max, depending on model.

 

[lefty2]

I'm wondering is it valid to compare a Cinebench 32-bit result with a 64-bit result?
Also, seeing as this chip is running at > 2Ghz turbo, maybe you should be compaing it with the A6-5200.

With all cores under load it will probably run at 1.47 Ghz. We don't know for sure but turbo is usually only active when one or 2 cores are loaded and not all 4.

Good. Less pointless talk and PR and more actually confirmed facts would be nice. Would be nice if some actual devices would soon ship to market soon, even in small quantity - so some early adopters could buy them and test them - so we all could see personal non-portal, non-known-blogges numbers and videos too.

I do appreciate good PR campaigns and hype building - it's mildly entertaining and even a little interesting from business point of view, but in last years many products (not just computing hardware) are getting insanely long and intensive campaigns and it's getting old fast.

I think you should ask MS about it.

 

[Gikaseixas]

It's only a matter of time before Intel rules mobile from head to toe They're committed and hungry for success in that area.

 

[ShintaiDK]

So Silvermont looks like a fantastic winner chip. 2W SDP chip.

 

[fusion238]

Looking at the chart, Intel gimps their Baytrail Atoms with 1/2/4 GB memory limits. If that were not enough insult, users will be hampered with eMMC based drive I/O!

Being able to use a low cost but high quality HP Touchsmart 11 with AMD's Jaguar based A6-1450 that boots to login at around 12 seconds (even with a 5400 rpm drive!) and allows 8 GB memory expansion and SSD as upgrades...makes me wonder if Baytrail is too little late...

Are you comparing a tablet CPU with a notebook CPU? Also the Silvermont one uses a fraction of the power than the Jaguar based one.

AMD got nothing in this range.

What precisely is wrong with a good eMMC implementation? Baytrail supports the eMMC 4.5 standard which apparently has an interface bandwidth of approximately 200 MB/s. So the chip itself is capable of acceptable speeds, question is how it'll be implemented in actual product designs. I'll definitely agree that the memory limits are somewhat disappointing, but I doubt they'll have any effect in their intended markets. (After all, what are the chances that manufacturers are even going to equip these tablets with 4GB of memory?)

 

[lefty2]

With all cores under load it will probably run at 1.47 Ghz. We don't know for sure but turbo is usually only active when one or 2 cores are loaded and not all 4.

Not necessarily, turbo can work on all cores for short amounts of time.

 

[Exophase]

CloverTrail+ could turbo up to 2GHz (not sure what the base clock was, 1.5GHz?), didn't stop early benchmarks from leaking as running both cores at 2GHz. This was in a phone thermal envelope (K900). Who knows what clock speeds this was running at. Cinebench generally does substantially better in 64-bit than 32-bit, meaning that if this score is really at ~1.46GHz the perf/MHz is even better than Jaguar. I don't believe this at all, especially not for a load like Cinebench.

Not that this isn't a very good score even if it has to run all four cores at > 2GHz to achieve it. I just don't think that's really going to be 2-3W territory.

So you're saying my BayTrail tablet which will deliver years more batterylife than your jaguar AMD laptop, deliver similar performance to my current penryn laptop, and be quite cheap (according to intel at least), will only have the downside of having 4GB of ram, which is more than any tablet out since I think the latest tablets/phones have 3GB of ram (Samsung Galaxy Note 10.1 and Samsung Galaxy Note 3).

Even better, you're saying my BayTrail laptop, will be even BETTER than my tablet?

I think I can live with that....

 

[blackened23]

I was about to say - those AMD APU laptops have pathetic battery life. Have battery life tests been done on Jaguar laptops? All indications I've seen show 4 hours or so. Not impressive, unless I have bad information. If anyone can clarify real world battery life on the Jaguar, please do so.

Bay Trail should do better than the original Atom - which had great battery life but terrible performance. I expect good things here in that respect. I also don't see DRAM as an issue since these are aimed to tablet SKUs, with many of them running Android.

 

[tential]

Maximum of 4GB of ram on a tablet, is fine considering tablets only use 3 GB of ram. How often will intel be refreshing this? Is this an every year tick/tock thing like they originally announced? Because if so then this limit will disappear soon anyway.

I can't wait for the batterylife but I feel it might be disappointing. We kind of new Haswell would bring amazing batterylife because of the hype. If BayTrail had AMAZING batterylife it would probably have been hyped b y now but who knows. On the mobile processor side I wouldn't be surprised to see 16+ hours of battery life though.

 

[blackened23]

The original Atom achieved 7+ hours fairly easily and that was on a dated lithography process. I highly doubt battery life will be an area in which Bay Trail disappoints..

Personally, this (battery life) is what excites me the most. I love the fact that an iPad basically lasts forever on a charge, and i'm waiting for something other than the macbook air to deliver similar results. Hopefully Bay Trail will be that product.
