TI's OMAP 4430
You have to hand it to NVIDIA, up until the launch of the iPad 2 if you were talking about a dual-core tablet or smartphone you were likely talking about something running the Tegra 2. Both Qualcomm and TI are late to the dual-core SoC game, but with the PlayBook we have the first shipping device based on TI's Tegra 2 competitor: the OMAP 4430.
At a high level the 4430 looks a lot like the Tegra 2, but dig a little deeper and you'll see that the SoC should be faster overall.
Like the Tegra 2, TI's OMAP 4430 has a pair of ARM Cortex A9s running at up to 1GHz with a shared 1MB L2 cache. Unlike the Tegra 2 however, TI implemented ARM's Media Processing Engine which gives it both a pipelined FPU as well as support for ARM's NEON SIMD instruction set (think SSE but for ARM SoCs). It won't be until Kal-El before NVIDIA brings NEON support to its SoCs.
On the GPU side TI uses a PowerVR SGX 540 by Imagination Technologies. The SGX 540 has four USSE pipes (SIMDs) each capable of up to two MADs per clock.

| PowerVR SGX 530 | PowerVR SGX 535 | PowerVR SGX 540 | PowerVR SGX 543 | PowerVR SGX 543MP2 | GeForce ULP | Kal-El GeForce | |||
| SIMD Name | USSE | USSE | USSE | USSE2 | USSE2 | Core | Core | ||
| # of SIMDs | 2 | 2 | 4 | 4 | 8 | 8 | 12 | ||
| MADs per SIMD | 2 | 2 | 2 | 4 | 4 | 1 | ? | ||
| Total MADs | 4 | 4 | 8 | 16 | 32 | 8 | ? | ||
| GFLOPS @ 200MHz | 1.6 GFLOPS | 1.6 GFLOPS | 3.2 GFLOPS | 6.4 GFLOPS | 12.8 GFLOPS | 3.2 GFLOPS | ? | ||
At the same clock speed, the SGX 540 has the same theoretical compute potential as the GeForce in NVIDIA's Tegra 2. The SGX 540 is a tile based renderer and thus tends to have an appreciable memory bandwidth advantage in current smartphone/tablet gaming workloads.
TI's memory interface is often touted as a significant performance advantage for the OMAP 4430. While NVIDIA has a single 32-bit LP-DDR2 interface, the OMAP 4 embraces a dual-channel (2 x 32-bit) LP-DDR2 interface giving it twice the theoretical bandwidth of what you'd get on a Tegra 2. NVIDIA argues that its bandwidth efficiency is high enough on the Tegra 2 that you don't need two channels, but it's honestly difficult to really validate claims like that.
The other major piece of the OMAP 4430 is its video engine, something TI calls the IVA 3 multimedia accelerator. This hardware encode/decode engine is what makes full 1080p30 playback and recording possible on the PlayBook. As you'll see in our video tests, the PlayBook is the first ARM based tablet we've used that can decode a 1080p H.264 High Profile video stream.
Overall the OMAP 4430 has the specs to be performance competitive with anything else out there today, definitely anything Tegra 2 based. Apple's A5 still has a much faster GPU but from a CPU standpoint, the PlayBook should be competitive. Any non-3D performance differences would likely be due to software optimization, not hardware limitations.

That is a curious statement. What do you want lots of memory for?I can see memory being better for a phone that you listen to music from as more memory = more of your (compressed) library can fit on it. Personally I only sync particular playlists to my phone / iPad anyway.
As for other stuff, well apps just do not consume a large amount of space. For my iPad 2 I went with the smallest memory size. The larger size I have on my original, er I mean on my sister's "new" iPad, was just a waste for me.

Because it's an easy way to share things and upgrade your memory if you need more. I won't pay 100$ for 16GB of NAND flash (which cost's like 15$).jjj - Thursday, April 14, 2011 - link
For a device that can shoot and play 1080p video 16GB-64GB of storage is very little (and anything above 16GB is way too costly) Then there are also photos,music,apps that maybe soon will be actually able to do things and become bigger,it is after all a computing device and even if smartphones/tablets are in their infancy we can still hope that they mature sooner rather than later.BuffyzDead - Thursday, April 14, 2011 - link
"The screen is too small to comfortably read in portrait mode and even in landscape things can get a bit cramped." Steve Jobs already warned the entire industry on this point. It's too small to be a successful tablet. Everyone has portability in their Smartphone."Apple's A5 still has a much faster GPU" .and the playbook isn't even shipping yet
"App launches are unfortunately a bit high latency. .....whole process takes a couple of seconds but it feels longer than firing up similar iOS or Honeycomb apps." just throw more CPU at the problem. You know, down the road.
"With no email or calendar apps, the PlayBook doesn't have a whole lot to notify you of. Presently the only notifications the PlayBook will deliver have to do with remaining battery capacity." LOL at this one.
I predict Now, this thing will never sell in volume. Even improved versions down the road won't sell.
3 reasons:
1) It's too small.
2) The User Experience does not even come close to that of the iPad1
3) NO APPS
Yes, while there are company's that may force this down their employees throat, that is not where the growth of tablet use is coming from, in enterprise.
It's coming 100% from employees wanting to use their iPad's in the work environment.
You finish with:
"there are still more revolutions that will take place between now and when the mobile market finally matures"
Ask yourself, Honestly, is there ANYTHING about this "experiment for RIM"
that has an inkling of REVOLUTION ????
Azethoth - Thursday, April 14, 2011 - link
The proper quote is:"While Apple and Google are clearly out to a substantial lead, there are still more revolutions that will take place between now and when the mobile market finally matures. I'm not saying that Apple or Google won't end up on top, I'm just saying that it's not guaranteed they will either."
and
"The PlayBook is a reasonable experiment for RIM, but I need to see more to really recommend the tablet."
See how in context Anand makes sense? Rather than claiming the ridiculous: "this RIM tablet is a revolution", Anand is merely saying that this is an immature industry. Everyone fully expects actual game changing revolutions in this area in the future.
Search this site for Anand's excellent follow up to the iPad 2 release that asks: "How do I as a blogger use a tablet to create [text] content". There were some responses about maybe covers that double as keyboards. There was wishful thinking about voice input maturing real soon now. Mostly there is a need for some kind of interface revolution before a tablet can become a reasonable answer for a blogger on the go. These are the revolutions Anand needs in a tablet.
BuffyzDead - Thursday, April 14, 2011 - link
Correct !I wholeheartedly agree with Anand's review and conclusion:
There are no guarantee's what the future may hold and he can not recommend this Playbook.
1) I wanted to add that this Playbook will in fact be a total failure. Time will prove me right or wrong. Again, I predict Total Failure.
2) I wanted to point out how RIM, as is evident by this Playbook version 1,
has demonstrated Zero in it's capability to provide ANY REVOLUTION.
At most, it's an outright attempt to copy or emulate (poorly) what the iPad REVOLUTION IS.
BTW,
If you think that "designing a tablet" to cater to "the blogger on the go" is a measure of success, then I pray for RIM's sake, you are not on their design team.
Anand has repeatedly pointed out how a tablet might just not be for him, in general.
I have maintained for the past 15 months that the iPad's true REVOLUTION, is that it CREATED a NEW MARKET.
ALL of Apples competitors are playing catchup & copycat to cater to that NEW MARKET, which the iPad CREATED.

For real... lay off the coffee and Jobs shlong.melgross - Thursday, April 14, 2011 - link
For real, it's the only tablet so far that sold more than a small number. As many others have pointed out, so far the tablet market is really the iPad market. Other manufacturers have to prove that they can sell a large number of devices. We know that the Tab, is not a real tablet by Google's standards, and that it sold in much smaller numbers than the number shipped to retailers and cell companies. The Xoom is assumed to have managed about 100,000 sales, and what else has there been that seriously competes?Now, the Playbook, which has been criticized by those in the industry for having poor battery life, and problems with the software before release, despite RIM,s denials, is proving, from all the reviews I've now read today, to be having all of those problems just days before release. Pogue has stated that RIM is feverishly sending out updated on a daily basis. That's not good.
Other tablets won't arrive for at least a couple more months.
So what does the market really consist of now?
melgross - Thursday, April 14, 2011 - link
It's hard to say. There are a lot of writers who have said that they type just fine on the iPad's virtual keyboard. Everyone's different. I remember a lot of people complaining about the first iPhone's keyboard, but since then, many, if not most new smartphones have no physical keyboards anymore, so people are getting used to them.I'm typing on my iPad2 now. The only complaints about the way Apple set it up are that I think that too much space is wasted on the two large numeric keyboard call up keys at the bottom of the keyboard, much of which could have been used for other functions, such as an "@" key, for instance. Otherwise, it's fine. On a 7" screen, typing for longer periods will be more problematical.

Stop trolling, and PLEASE grow up.Thanks.
