Re: Mobile System on Chip Thread
 

Nice, I was wondering what Qualcomm was waiting for. They're undeniably late/slower than the competitors which sort of slowed HTC in the market, I speculate.

But I can't shake this feeling that the OMAP 4430 should perform better than shown. Cause the 4440 is the current beast:
+TI closesly collaborates with ARM and usually polishes up the reference desing (where others just look for areas that they can modify and cut costs).
+TI adds extra functions such as various DSPs and sound modules.
+And the SGX540 is more powerful than the Adreno 220, just barely.
=Going by several guestimates the 4440 should do something close to 40-44fps on that benchmark.

I'm guessing the "appauling" results by the Optimus 3D maybe due to a smaller RAM, underclocking, a biased benchmark (not suprising given Qualcomm's involvement) and most likely dodgey drivers by LG (imminent).

Anybody else notice the iPhone 4's bad results, seems like a biased-benchmark considering the A4 SoC should be on par with the T-mobile G2. However the code is executed by C/C++ or Objective-C which is several layers closer to the cpu/gpu (hardware accelaration) on the A4 than Android's java-implementation. So Apple should have a boost/advantage over the Android competition but the effect seems to be opposite according to those figures.

Re: Mobile System on Chip Thread
 

These benchmarks are not gospel. They indicate performance under very specific circumstances -- circumstances that are not real-world. It's also hard to make inferences about implementation based on them.

You're also making the mistake in thinking that Android's Java implementation is used in these benchmarks. It is likely not. Android has an NDK which allows Android programs to execute native compiled C/C++ code (though prior to v2.3 the ndk may be called from within a thin java app -- though I would guess that 99.9% of the time is spent native).

Another of thing that may not have been considered is that many of these tests (if not all) are restricted to running on the devices native res. So devices with a higher res are at a natural disadvantage (more pixels).

Interesting benchmarks here:

Looks that the OMAP 4 wins the round.
BTW Do the tags remind you with something?

Re: Mobile System on Chip Thread
 

It seems that the Exynos 4210 (then Orion) indeed has 4 fragment processors in the Mali400 implementation.

This is very good news.

It seems that ARM is hear to stay in the mobile graphics space. Their GPUs look to compete with Imagination, the reigning champ, and NVidia's upcoming powerhouses.

Let the games begin!

Re: Mobile System on Chip Thread
 

So is the Mali 400 like an SGX543MP4 where it actually has 4 graphics cores working in tandem ... or is it just one core separated into four units to handle different types of graphics handling (shaders, tesellation etc etc).

I would prefer the first method, although it is less power efficient, you will see the performance increase instantly. And since things are already quite power efficient (durr ARM) I think that point is less important.
Whereas the latter may require a specific optimization on the software end to take advantage of its unique architecture ... (and you know how often things are done properly these days).

Re: Mobile System on Chip Thread
 

I would assume that the 4 fragment processors are for calculating shaders and are running simultaneously on different workloads (why else have separate cores?). But I will look into that more earnestly. I'm not sure if any of the current breed of SoC GPUs handle tesellation natively, though I suspect that a talented developer could shoehorn something that functions similar into an algorithm.

It also seems that ARMs drivers specifically take the complexity out of scaling to multiple fragment processors when programming, but I suspect that most SoC GPUs are similar in this regard.

I would love to see the power requirements of the chip overall. Unfortunately this information seems hard to come by!

The Exynos 4210 and Mali400 seems very, very fast, though. I'm looking forward to some proper benchmarks with mature drivers.

The next iteration of the Mali, the T604G, looks to boost this speed by another 4-5x! It may in fact start to rival current console games in graphics, and display this content at 1080p.

Re: Mobile System on Chip Thread
 

It seems as if the next Sammy SoC is getting the bump to 2GHz :eek:

Coming to a smartphone in you in 2012:

http://www.gsmarena.com/samsung_read...-news-2528.php

I doubt this is simply a increased clock Exynos 4210, though rumors suggest that it may be an Exynos branded SoC.

At these speeds, I have little doubt that SoCs will have begun to converge with low-power laptops and netbooks in performance. Spry OSs like Android, iOS, PalmOS, MeeGo, WP7, etc, that have been written to perform very well given confined resources, should elevate the 'feeling of speed' of applications beyond that on the laptop.

Re: Mobile System on Chip Thread
 

It seems that Qualcomm is bringing the heat, and this time is targeting ARM with its latest SoC designs:
http://www.mobiletechworld.com/wordp...tgen_watts.jpg
http://www.mobiletechworld.com/2011/...ter-this-year/

The next generation Quad-core Snapdragon is claimed to be more powerful than ARMs upcoming Cortex A15 design, scales to 2.5GHz @ 28nm, lower power (half at max), and available at the end of this year :eek:!

The source link has a bunch of data visualizations to help put the chips performance in perspective.

My question: CPU speed is one thing, but can the next-gen Adreno GPU keep up with the onslaught of incredibly performing mobile GPUs?

Re: Mobile System on Chip Thread
 

The Next Adreno in the next-gen quad-core Qualcomm MSM89xx SoCs will indeed be the Adreno 320.

There is speculation that samples will ship in early 2012, so we will not see devices until late 2012 at the, uh, earliest. Around that time, the MSM will have to compete with Cortex A15s and Mali T604s, as well as whatever Imagination is cooking up with the PowerVR lineup.

While the on-paper specs look mighty impressive juxtaposed against today's array of SoCs, I'm betting that they will look all the more dull when contending against tomorrow's.

Here is the press-release:

Re: Mobile System on Chip Thread
 

Pretender to the throne: OMAP5 roadmap hints at raw power:

Will it be enough to contend with the MSM8960? Qualcomm is claiming more performance at lower power.
