Of course, their claims of running Samaritas with a single kepler GPU is also questionable... 😉

They didn't say it was going to be running at 30fps :)

I expect these claims from Apple to be outright false advertisement.

I'd be surprised if Apple were so dumb as to blatantly use false advertising. I'm guessing they used cherry picked test conditions to show the A5X as favorably as possible, and Tegra 3 as unfavorably as possible.
 
According to these benchmarks (http://www.anandtech.com/show/5163/asus-eee-pad-transformer-prime-nvidia-tegra-3-review/3), the A5 is 1.1-2x as fast as Tegra 3… so if the A5X is twice as powerful as the A5, then it would appear Apple's claims are accurate.
 
Everybody talks about the resolution and graphics.
I do not want to take anything away from Apple, the display must be very nice. The question is how will it be used? The HD movies are 1920x1080. Games are not there yet either.
Nobody is saying one word about USB, microSD, HDMI,... connectivity. I think these are very important too.

I read something about this too, and I think it stems from a max res of 1920X1080 on the game systems which is lower than the new Ipads display, and the fact that, I guess, the new Ipad has more RAM. Of course, its really an apples and oranges comparison.
 
hate everything that starts with i....so much restriction and control... "i" stands for apple not the individual Simply said: my way or the highway I chose highway.
 
I would almost guarantee that they're comparing the chips in single-thread applications, specifically finding some app that works better on A5X's architecture. There's no way that Apple's dual-core has 400% the raw processing power of Nvidia's four+one core chip.
 
Should this really be that much of a surprise? Apple has been known to provide misleading information often enough just look at all the Mac doesn't get virus's or more stable than Windows commercials ... Mac's most certainly do get virus's and its stability compared to Windows is debatable but if you consider that the average consumer doesn't know how to think for themselves it makes sense. There are people that will buy an item based on name brand alone or because it's popular at the time regardless of the price.
 
Yep, I brought this up in the ipad announcement article... I'm guessing that 2x/4x figure was a bit of a stretch at best, and downright misleading at worst. But I agree, I don't think it was an outright fabrication. Apple can probably pull out some cherry-picked benchmark from somewhere to back up their claims. But it would be far from representative of average real world performance.

Agreed. Marketing is how Bose and Dyson survive. As I see it, "marketing" makes this world a buyer beware world whether we like it or not.
 
So, your Angry Birds will now run at 2000 fps, and you web pages will load 0.0001 seconds faster( sorry, but your connection latency is still the limiting factor ), congratulations. Of course, this is great news for the 100 people that use a tablet for something else than the 2 above-mentioned past-times.
 
This is one of the few tech articles around that points out that a quad Graphic A5X is not a quad core CPU its a A5X with all be it probably much more graphic power. Am I say that it wont increase speed no but iv read at least 8 articles that say the "new ipad" is faster with LTE and a new quad core processor which is super misleading.
 
"The ASUS Transformer's GPU is only 12-cores..."
More cores doesn't always mean better performance..
Remember the 8-core gpu in the Tegra 2 ? yeah that one was completely smoked by the 4-core Mali gpu in the exynos SoC, and I hate to say this, but both were vastly outperformed by the 2-core SGX543 MP2 gpu in apple's A5...
 
A5 has among the best graphics in any of the ARM devices, if not the best, so it;s not unreasonable for the A5X to be even three or four times more GRAPHICALLY capable than Tegra 3. However, it will not be computationally better. However again, that doesn't matter if the A5X's two cores are fast enough for it's graphics, which they undoubtedly are. Now it needs to have enough memory bandwidth to support the graphics, then there's the rest of the phone and it's connectivity, and more.

Regardless of that, Apple should have provided hard facts and realistic benchmarks and none of the using non-optimal condition crap on the competition. Apple likes to jsut say they are better rather than prove it. This makes me assume that the A5X really isn't that much better than the A5 even though it probably is. Remember, just like in CPUs, core count is NOT everything in graphics. IPC, clock rate, memory bandwidth, and more are also important.

Intel's dual core CPUs beat AMD's everything in gaming and Nvidia's cards have far fewer cores than AMD's but they more or less compete anyway. IE the GTX 580 has 512 cores, 7950 has 1792 cores, but they have similar performance at stock anyway.

You mean to say that a device coming out in 2012 is faster than a console launched in 2005?

Don't forget, we will see sub $250 Tegra 3 devices, and all A5X iPads are $499+
