GPU Performance - GLBenchmark 2.1

While Intel's Atom core is a newcomer to Android, the PowerVR SGX 540 used in Medfield's SoC has been around the block quite a bit. Most recently, Samsung's Galaxy Nexus used an OMAP 4 that features the same SGX 540 GPU. The GPU clock is a bit higher than we're used to at 400MHz (vs 304MHz for the Galaxy Nexus), but otherwise the design and its performance are both known quantities.

We start with GLBenchmark, one of the better Android GPU tests on the market today. There are two benchmarks, Egypt and Pro, and each is run in two modes: native screen resolution and offscreen (vsync disabled) at 720p. The latter is more useful for apples to apples comparisons as everything is rendering the same number of pixels, whereas performance in the onscreen tests is determined by the screen resolution of the device along with the performance of its GPU.

The X900 falls in just behind the Optimus 3D, which shares the same GPU but is running at a lower resolution. All things considered, the X900 does reasonably well here but it's definitely not leading the pack.

GLBenchmark 2.1 - Egypt - Offscreen (720p)

At the same display resolution and without any vsync limits, the X900 falls significantly behind the cream of the crop. Despite the GPU clock advantage, Medfield is no faster than OMAP 4 in the Galaxy Nexus here which is a bit perplexing. We're either bumping into a memory bandwidth limit or some other CPU/driver limitation. Either way, Intel definitely needs a faster GPU. We'll get it but not until early next year with the 544MP2 in the Atom Z2580.

The Pro results actually show us more of what we expected to see:

GLBenchmark 2.1 - Pro

GLBenchmark 2.1 - Pro - Offscreen (720p)

The offscreen tests give the Medfield based X900 a 25% advantage over the Galaxy Nexus, which makes sense. The Droid 4 is closer than that, despite also using the same GPU.

Basemark ES 2.0 V1

Rightware's Basemark ES 2.0 V1 is an aging GPU test that tends to favor Qualcomm's Adreno GPUs above almost all others. The Imagination Technologies based GPUs, such as the SGX 540 used in Medfield (as well as NVIDIA's Tegra GPU) don't fare as well here. Intel's GPU clock advantage does show up a little bit in these tests, making it the fastest PowerVR SGX based offering here:

    ...so, suddenly it becomes more than mere opinion when you say the opposite? You have to admit you're on shaky ground with that line of argument.

    "Could benefit from being thinner" isn't quite the same as "too thick". I suspect you mean the former?

    Its not an opinion when its true. Phones should stay below 1CM thickness, and even 1CM is pretty beefy. Many people will not consider it due to this and not having a real huge advantage anywhere else.

    When all else is roughly the same, comfort and aesthetics decide a buy.

    1 cm is *way* too thin for anyone with "normal"-sized hands.

    Compare the aesthetics of holding/using a cordless phone, an office phone, a corded-phone, basically any phone handset other than a cell phone to a cell phone. Which feels more comfortable in your hand to speak into for more than 3 seconds? The one that fits nicely in the palm of your hand, that nicely curves with the natural lines of your hand (aka everything other than a cell)? Or the one with sharp edges, barely 1 cm thick, that requires you to use the muscles in the sides of your hands to grip, leading to cramping if you actually try to, you know, talk, on the phone?

    Today's cell phones are too thin, and battery life is suffering for it.

    Definitely an opinion. If someone wants a keyboard it's going to be over 1 cm. There are people that put their phone in cases and the result is way over 1 cm. The Otterbox Defender is somewhat popular, and the phone becomes almost 3/4 inch thick. Reply

    On the general issue of "phone-thinness" rather than this phone in particular no doubt the same people who want the mobile equivalent of an anorexic catwalk model will then start howling about the battery life in their super-thin phone where there is scarcely room for a battery at all, let alone one with decent capacity. Perhaps we should be discussing the fact that some customers' contradictory "want my cake and eat it" demands indicate that the topic should be that some of the customers are too thick rather than the phones.

    I find the "a bigger battery is all we need" argument rather weird in the context of the thickness. It's not like Intel has not already considered this trade off. It's lighter than I expected though.

    The trouble with reviews like this (and this is not a criticism) is that SOC price is not considered, nor that fact that the mobile industry really would rather Intel, and its monopolistic/margin desires, stay away. Benchmarks (unless paradigm breaking) are not going to change that.

    So far, I do not believe Intel has a single true design win, they paid for them all.

    profit margins for ARM and Intel as a whole company, if this page can be believed, are similar

    we dont know what that phone will cost in the US, but for a phone that costs $420 with that performance???? ARM will be pissing in their pants right now if it had the performance of A15 on that phone. Reply

    Knowing that it can't keep up against already existing platforms introduced a while ago it is a failure. Don't see any reason why to buy this mobile phone, it doesn't have any added value against any other major competitor.

    not on price/power/performance.

    so it is doomed before it is even released.

    lets see what the tablet brings, but it doesn't look good at all. It all starts with the Atom which has never proven to be a good arch.....

    For a first attempt (Moorestown was always going to fail, so I don't count it :P) it really isn't that bad. It pretty handily beats the A9-class SoCs from last year while being somewhat competitive with the S4 running ICS. I'm curious to see if the Medfield ICS build gets better performance.

    I don't know how much Medfield phones will cost, but if it comes over here as a $420 off-contract device, that places it pretty firmly in the mid-range, where it would certainly be pretty competitive with the A9 devices that will be down there.
