Raspberry Pi Should Achieve "2X The iPhone 4S Performance"

By - Source: GamesIndustry | B 32 comments

The Raspberry PI will supposedly outperform the new iPhone 4S across a range of content.

In an interview with Digital Foundry, Raspberry Pi executive director Eben Upton claims that the little $25/$35 credit card-sized PC will crank out twice the performance of the iPhone 4S "across a range of content." He even trashes Tegra while comparing his home-grown GPU core to Nvidia's mobile solution.

"I was on the team that designed the graphics core, so I'm a little biased here, but I genuinely believe we have the best mobile GPU team in the world at Broadcom in Cambridge," he said. "What's really striking is how badly Tegra 2 performs relative even to simple APs using licensed Imagination Technologies (TI and Apple) or ARM Mali (Samsung) graphics."

"To summarize, BCM2835 has a tile mode architecture - so it kills immediate-mode devices like Tegra on fill-rate - and we've chosen to configure it with a very large amount of shader performance, so it does very well on compute-intensive benchmarks, and should double iPhone 4S performance across a range of content," he added.

Also in the interview he revealed that the Raspberry Pi can be overclocked, although users won't be able to push it more that 100 MHz above the current 700 MHz core clock speed. "The ARM is already fairly close to the edge at 700 MHz," he said. "Without overvolting the chip (which decreases lifetime), there's not much more than 100 MHz of overclocking headroom on typical silicon. We do offer a clock speed tweak option in the boot configuration parameters, so if you get lucky and get a fast part you can exploit it."

Upton also indicated that his team has talked with Microsoft about using Windows 8 on the device, but the upcoming OS will require an ARMv7 (Cortex) processor, and won't run on the Raspberry Pi's current ARM11 core. A future version might support the new Windows platform, as there seems to be a lot of interest in running Windows-based applications.

As it stands now, Raspberry Pi runs Linux which will play host to a wide range of programing environments. Already lined up for the credit card platform are Scratch, Logo and Kid's Ruby for younger children and beginners, and tools like YoYo Games' GameMaker. Raspberry Pi will also support fully-fledged professional tools like Python and C. Even XBMC runs "beautifully" on Raspberry Pi.

After years in development, the first production run of 10,000 units will be available for purchase within the next few weeks. The basic version will cost a mere $25, and the $35 version adds more memory and an Ethernet port.

    Might have to get a couple of the $35 versions to play around with. Pretty interesting, overall.

    HellsbloodActually, no, Samsung currently hold that title with their Mali-400 GPU.


    Actually, the SGX543 is still faster, unfortunately. http://www.anandtech.com/show/4971/apple-iphone-4s-review-att-verizon/6

    Should I be impressed? Why not compare it to a good smart phone?

    $35 bucks? ? ? Is that for real? I'm going to buy two of them for my tv.

    It has one of the fastest mobile GPU's maybe?

    I'm definitely buying a few of the $35 ones :)

    I hate Apple just as much as the next guy but jeez dude give the 4S some credit. It does still have the fastest GPU of any phone on the market

    Well, I phrased that wrong because the Mali-400 came out first

    Actually, I was right the first time. The SGX543 is featured on the ipad 2 which came out before the Samsung Galaxy S II which was the first device with the Mali-400. Sorry for the extra posts which are mostly off-topic anyway

    So, what can I do with one of these things?

    This would make a great micro-console.

    Already have a Google TV but i'm interested in getting one of these to try out Ubuntu TV which looks pretty slick and alot more responsive than the damn atom in the Google tv (almost positive it's intel's crappy igp making google tv so unresponsive right now...)

    im pretty sure they will be sold out on the first day or two. If they offered preorders, they would be gone already.

    Surely he must be referring strictly to GPU performance. You're not going to outperform a dual-core Cortex A9 with a 700 MHz Arm11. If the GPU really outperforms everything else on the market today, why pair it with such a dated processor?

    dogman_1234So, what can I do with one of these things?

    oh boy so many things come to my mind. this little thing can do almost everything except playing crysis :p 
    I'm planing to buy 6 of those. 1 is going to a small server another is going to my octocoper one for my wardriving rig too, I'll also use one for my ipcamera it will be cheaper and I get to choose the camera I want, one for my tv, one powered by solar panels for remote monitoring.
    I just love this thing. now I just need to find some usb powered lcd and some more stuff *.*
    I've been waiting for this for a long time.

    "and the $35 version adds more memory and an Ethernet port." you forgot it also has 2 usb ports instead of 1.

    Here is one of the things I was thinking about when I originally started paying attention to the Raspberry Pi.

    with Apple, you're just basically paying for the name

    I saw over at the daily circuit that they got XBox Media Center to work on it. Crazy!
