  • iPad 2x Faster Than 3GS: Beats Nexus Too?


    "Fast" appears to be the most common adjective applied to the iPad since its release. Pretty much everyone agrees the new device is quick, but we're beginning to get a picture of how quick: two benchmarks run in recent days show the iPad is twice as fast as an iPhone 3GS, and appears to be quicker for some tasks than the Snapdragon processor in the Nexus One phone. Though the A4 system-on-a-chip (SoC) appears to have the same Cortex-A8 CPU as the iPhone 3GS, one observer theorizes that the speed bump is due to the fact that the iPad can read and write memory chunks two or three times bigger than other devices.

    Craig Hockenberry, the developer of the Twitteriffic app, Craig Hockenberry, did a series of tests clocking the speed of the original iPhone, running iPhone OS 2.0, back in August of 2007. Back then, the lack of an iPhone SDK meant that the device crawled, taking almost a hundred times longer to do many tasks in comparison to desktop computers. Hockenberry compared the performance of a new iPad and an unjailbroken iPhone 3GS and found that the tablet was between 1.5 and 3.9 times faster than the phone. "On average," Hockenberry wrote, "the iPad is about twice as fast as the iPhone 3GS when executing native (Cocoa Touch) applications," and from 1.2 to 2.4 times faster running Javascript. The iPad was between 12 and 8,750 times faster than the original iPhone running the 2.0 OS.

    Meanwhile, Anand Lal Shimpi at AnandTech ran some benchmarks comparing the iPad with the Nexus One phone. Both the A4 SoC in the iPad and the Qualcomm Snapdragon CPU in the Nexus are clocked at 1GHz. Since the two phones run different OSes, head-to-head comparisons were impossible, so Anand did some browser and Javascript tests to compare the CPUs and software stacks of the two devices. He found web pages loaded 10% faster on average and network-independent Javascript benchmarks gave the iPad a 37.6% advantage over the Nexus One.

    Any analysis of what might account for the difference between the two devices is going to be hampered by Apple's secrecy about the architecture of the iPad. Anand thought it likely that Apple had better interprocess communication due to improved design of Apple's custom SoC possibly including a faster memory bus. The A4's RAM is inside the chip itself, so iFixit had the reverse-engineering consultants at Chipworks go ahead and X-ray it to discover two stacked Samsung DRAM chips. David Carey, vice president of technical intelligence at UBM TechInsights, told the Wall Street Journal that these DRAMs read and write data in 64-bit chunks. "That helps it move a lot of data a lot faster," Carey said. "You are getting two to three times as many bits as would be characteristic in such products."

      Actually, Gb stands for gigabits, not gigabytes. The iPad has 2 gigabits of RAM (256 megabytes)

      I can't believe how close the nexus is, srsly apple u ganna let googles phone be damn near as fast as your tablet, kinda bummy apple, can't wait to see it compaired to the slate

      2Gb's of ram beats the hell out of netbooks.

      So you people are impressed because a thing that's 5x bigger than an iPhone is 2x faster than cellphones?

      You dont get it do you? my point is that they are comparing with a ******* tablet while the nexus and iphone are PHONES

      Yeah but this comparison shows having a device with an equivalent processor (1 Ghz on both the iPad and Nexus) that you are getting a TON more performance from the iPad even having to video render a MASSIVE screen because of the advanced chip architecture and integration. An intuitive hypothesis would be that the cell phone with a 1 Ghz processor would be a TON faster than an iPad with the same clock speed because it's only having to render a fraction of the pixels and isn't running large apps (in comparison) while in fact the outcome is counterintuitive.

      Thank you for this, because I'm guessing a lot of people here don't understand the importance of this comparison.

      On a side note: The Kenyan comment was awesome... made me want to bring this up...

      Bigger should be slower in some cases because it has to deal with a lot more. Nexus One and the iPad both have a 1GHz processor (I'm pretty sure this is correct, then again, I just woke up), yet the iPad wins. The iPad has more hardware and software to maintain and render.

      It's like putting a V6 engine in a sports car and an SUV. The sports car is gonna be faster with the engine because of its size and weight. This iPad vs. Nexus One comparison shows that in THIS case, the SUV is just as fast as the sports car.

      Hope that comparison helped... then again... I just woke up... lol

      totally agree, thank you for this to..
      also dosent this lead into the idea that the 4th gen iphone will have this same procesor?

      The tablet is faster then my nexus? NO WAY D:
      Of course it's faster. It's a tablet.

      Why is this thing being compared to a nexus one? Let's compare it to my macbook pro while we are at it if we are playing this game...

      Most people don't... I gave a perfect explanation of the relevance and then someone else gave a great car analogy and still people don't get the significance.

      I think you mean, "useless".
