Apple iPad 2 Preview
by Anand Lal Shimpi, Brian Klug & Vivek Gowri on March 12, 2011 6:01 AM ESTThe GPU: PowerVR SGX 543MP2
There are no spoilers here but the PowerVR SGX 535 in the original A4 is out, replaced by the new PowerVR SGX 543MP2. The 543 as a building block has a bit over twice the peak floating point throughput of the SGX 535. The MP2 just means there are two of these 543s working in tandem. The result is what Apple uses as the basis for their "9x faster" GPU claims. In practice the improvement should be less than that, but it's still enormous.
We've got GPU performance data coming, but I thought I'd take a slightly different route and show what one developer is using the extra horsepower offered by the A5 for.
Epic Games is a familiar face around these parts. We've used games powered by their Unreal Engine in our reviews for years now. More recently Epic has made a splash in the iOS world with the release of its Citadel demo and eventually Infinity Blade.
In time for the launch Epic updated Infinity Blade to have some special enhancements for iPad 2 owners. Rather than simply deliver a higher framerate for iPad 2 users, Epic enabled higher resolution textures and anti-aliasing. The resulting boost in image quality is astounding, particularly on the iPad 2's 1024 x 768 screen:

There's far more detail in the character models as well as the environment. Lighting looks improved and the AA is definitely appreciated.

The gallery below has a bunch of side by side shots showing the improvements made to Infinity Blade for the iPad 2 vs. what you get when you run the game on a first generation iPad.
As we mentioned before, the A5 (and iPad 2) are about enabling developers. In a year's time the PowerVR SGX 543MP2 will be found in the majority of iOS tablets on the market - and games are just going to get prettier from there.
Update: We've published a look at the performance of the PowerVR SGX 543MP2 running GLBenchmark 2.0 here. If you want a teaser, it's good:

Just divide out whatever whatever graphical benchmark result by resolution to get a relative power per pixel measure.On this subject, hopefully Anand can update this Preview with GLBenchmark results as soon as they are available rather than waiting for the Review. This will be a very interesting result and I think the SGX543MP2 can potentially be 3 times faster than Tegra 2 if the drivers are well optimized.

Please Adand could you tell me the point of this device?You can't carry it in the pocket, its not a gaming device, its not a texting/writing device, its not a office device, its worse than PC and laptops for everything and too big to have over a phone and not to mention no phone connectivity.
So it seems to me its just a huge, bulky web surfing device and even mobile phones have a better camera so its not good even for pictures.

This is exactly the device what I'm seeking. As most of the time in the evening I'm just websurfing/chatting with my girlfriend in Japan or emailing.I dont need to have a full blown pc to comfortably do this,
The ipad is fully supported by my cable provider. I can program the digital box with the device and watch a second program in parallel to my tv. Easy to follow two soccer matches :)
Apart from that I can control my home domotics system from my couch.
All this is the reason for getting the ipad.

Most people just use it as a toy..or a trend.The purpose is to bring things like reading books, browsing web, casual games, movies, etc..to a more mobile state than a bulky laptop with a giant keyboard attached. You can easily cradle it in your arms and walk around with it..sit in any position. Smartphones are more mobile, but not as comfortable to use in the sense that the Tablets have nice large screens.
They would be even more useful if they were all built like my new Eee Slate with the Wacom Digitizer technology on it. I do all of my computing on this thing now, especially all graphic & web design. The only downside is the battery life but it's good enough and worth it to have Office pro, CS5, and FL Studio on a tablet.

For me it's a device for reading technical PDFs. It does this far better than- a laptop (keyboard gets in the way)
- a kIndle (PDF display is crap for technical PDFs, not to mention SLOW)
- any Android device (faster, nicer screen, apps that handle the details, like margin cropping, well)
If you doesn't do what you need, why not just STFU? I don't run around the web sites for fancy camping equipment saying "Well, who really needs this equipment? Why don't you just stay at home where it is more comfortable?"

LOL, thanks for making me laugh.I always think along the same lines as your reply when people piss and moan about how something is useless to them, so no body else should want one and so it should cease to exist.

Speaking purely of my original iPad :1) It paid for itself by replacing my NY Times habit at Starbucks with various free news apps (NY Times & BBC being my favorites).
2) It made me fork over $100 for an Economist iPad subscription, doh. I really like the solid reporting they do.
3) It controls both of my Squeezebox Touch music players with nice touch interfaces and glorious album covers ($10 SqueezePad app).
4) Using the Calorie Counter app I have lost 10 pounds in the last 2 months. I could use it on the iPhone in theory but in that small a form factor ... just not gonna happen. Same on my comp, I am just not gonna run to the computer room every time I eat something, especially when not even at home. Another 20 pounds lost and I will be at a healthy weight: priceless.
5) I love reading, a lot. But my place cannot handle more paper books. I have read books using iBooks and the Kindle app. The iPad is fantastic for reading at night or twilight. I even read outside in the Sun, but not with the sun relfecting off the pages. But thats ok, I do not read regular books with the Sun bouncing off their pages either. The only scenario not supported is reading in a nice warm bath: I cannot have my iPad get wet.
6) Home automation. It is a niche thing but the iPad is a breakthrough interface in this arena. I am just getting started but I can control the furnace, a/c and fireplace so far.
7) Free phone calls using skype & wifi.
8) I use a small leather backpack to lug it around along with my coffee mug, water etc.
9) It is a gaming device. My favorites are Plants vs Zombies, Infinity Blade and Osmosis. I have played more games on it than my XBox, although Kinect is changing that. It does not replace PC gaming, but it enables games not possible on the PC.

So it other words its just an expensive, huge and bulky device just for web surfing.In better times we would call people that purchase these things stupid, laugh at them for making a bad choice and educate them how to recognize true value for money and make a smarter purchase tomorrow.
Guess times have changed for the worst, where the unacceptable is acceptable and the worthless is cool and trendy.
Whats next they are going to invent a Stone 2.0 with WiFi and an apple picture of the back of it and people are going to shell out hundreds of dollars for the cool rock 2.0.
Amazing, just freaking amazing.

Sniff, sniff... can anyone else smell an angry troll?slickr, I am sure you're just trolling, or deeply jealous, but if not, just buy an iPad and see for yourself. It's frankly a device you can hear about a million times and never get it till you use it. There's just something magical about software always working, having an app for just about everything you can think of, and enjoying superb mobility, etc. Cooking? Just attach it to your kitchen cabinet and watch a video instructing how to make a dish. Taking notes in class - perfect companion! Want to connect to your windows pc remotely from your couch and still enjoy touch screen? Done.
And yes, the games rock. And they'll rock 10 times as much once they learn to use iPad 2's power.
TO ALL OTHERS: I just got hdmi adapter for this and I have to say, it's amazing for gaming! Now I can play and girlfriend can watch on big screen. But it's even better with games that don't require use of touch screen, such as Real Racing which can use just the accelerometer. Sooo recommend it. It's becomes a mobile xbox almost ha

Yeah I'm sure slickr is just jealous. He wants to be a dumb yuppie. Some people live and die by these money black hole devices. As soon as you start paying for something due to its "coolness" factor, it's all over... Bottom line is these are $200 devices. They offer nothing vs an ipod touch, except the ability to hold it a bit further from your face.
