GPU Performance

GPU performance is another important aspect of a device, and with display resolutions increasing there is always a need for more GPU power to drive more pixels. In the eyes of many consumers, Intel is not typically associated with speedy GPU performance, particularly in the mobile space. Many readers commented on the poor performance of Intel's HD Graphics in the Stream 7 review. However, one of the ways Intel's Moorefield chips are differentiated from some other chips in the Atom line is that they use PowerVR graphics. In the case of the Venue 8, it uses the PowerVR G6430 which was used previously in Apple's A7 chip.

There has historically been a noticable gap in performance between a given PowerVR chip implemented in an iOS device, and the same GPU in an Android device. Due to drivers and other software factors, the performance of the Android device is typically slower. Because of this, I've marked the iPhone 5s on all the charts except for the onscreen ones so comparisons can be drawn between the performance of the G6430 GPU on different operating systems. In the 3DMark graphics test, the Venue 8 actually scores higher than the iPhone 5s, and in the GFXBench tests there is not a large difference between the two devices. In Basemark X there is a sizable performance difference between the two devices in favor of the iPhone, but overall I don't think anyone should be concerned about massive differences in GPU performance between the G6430 running on iOS and it running on Android.

When evaluating the Venue 8's GPU performance on its own, it can hardly be said that it's slow. However, it's now competing with Apple's 8 core Rogue GPU in A8X, and NVIDIA's Kepler graphics in Tegra K1. The devices with those GPUs end up performing between two and three times faster than the Venue 8 in many cases, and with Tegra K1 that GPU power is available in NVIDIA's Shield Tablet which undercuts the Venue 8 at only $299. GPU performance has simply moved onward from when G6430 was leading the pack, and although the Venue 8 isn't exactly slow, it's outgunned by other devices that meet and even beat its price.

NAND Performance

The performance of a device's internal storage has never been a large point of focus in the past. Mobile device manufacturers don't advertise anything about their storage beyond the capacity. However, the speed of a device's NAND can have a significant impact on performance. Slow memory can be what bottlenecks a system's performance when any sort of heavy reading or writing is occurring in the background, which occurs more often than one would think due to background applications and tasks like automatically downloading and installing app updates.

In all of our tests, the Venue 8 is decidedly average. There's no situation where it shines at the top, but also no cases where it's significantly worse than the competition. I wouldn't expect the Venue 8's storage speeds to cause any performance issues for users, though it would be nice to see at 32GB NAND option at this price.

    Yeah, this was a really well done review. Thoroughly enjoyed it even tho I'm not a dell fan.

    My primary interest in this is that it has the same chip as in the Zenfone 2, I wonder how much it will have to scale back for a smartphone form factor. Seems like that could be the next budget champ, since it should be closer to the Snapdragon 800 than the 400.

    I find it less disconcerting that Dell made a WiFi only version that is being mistaken for a flagship tablet than the fact that it remains difficult to figure out from AT reviews whether there is an LTE version of any given tablet.

    For a flagship tablet review, this should be prominent in the Connectivity section, if not in the Introduction. Flagship tablets have everything but the kitchen sink thrown in - and that is the way it should be.

    There is nothing wrong with the manufacturer making a WiFi only version. It is just that doing so will automatically make that version of the tablet a mid-range tablet. Maybe, upper mid-range - at best, if we are being charitable and they nailed everything else down perfectly.

    4G LTE and GPS radios are mandatory for a tablet to be considered a true fully equipped flagship because it represents the peak level of equipage possible. Those who need it know why they need it...

    ...and AT should make it easier for us to figure it out... instead of having to sort through a pile of chaff to figure out if we are even interested in the article at hand. As it is, these type of muddled articles border on being clickbait.

    If it were not for a helpful reader's comment, I wouldn't even know that Dell has produced LTE versions in this class of device.

    In addition to asking whether Dell is interested in providing full flagship value, I'm finding myself asking the same of AT.

    I apologize for not listing it in the chart on the first page. However, it was mentioned in the WiFi section. I've added it to the connectivity cell in the spec chart to make it easily accessible.

    @hrrmph -- I'm sorry, but you are sorely mistaken with your comment about a flagship tablet absolutely having to have a 4G LTE radio. Adding in a cell radio usually increases the cost of the tablet much more, and you can have the exact same tablet without it, and it's still considered flagship. So what are you saying is that an iPad Air 2 with a cell radio is a flagship device whereas the same iPad Air 2 without is not? That's just ridiculous. any iPad Air 2 is a flagship device -- period. Many tablets are used just as a media consumption device at home with WiFi. And as someone mentioned earlier, you can also many times use your phone as a hotspot to get cell coverage for the tablet.

    As a tablet doesn't have to have a cell radio, it can still be a flagship device. So you can have a flagship tablet with and without a cell radio -- it's as simple as that.

    By the way and off topic, nice Google+ avatar Brandon. One of the best Anime in recent times.

    Back to the review... Great review. I was also someone really wanting Dell to succeed on this one since I'm still on the lookout for a Windows tablet and Dell seems to have a bunch in the pipeline. Kind of disappointed at this device, but also somewhat expected considering they're not really the first choice when it comes to Android tablets.

    Dell recently updated their Venue 11 Pro tablet line with the Core M 5Y71, and that, along the Asus Transformer Book T300 Chi, which is not out yet, is on my radar for a future purchase. If you guys could get reviews on those devices, that would be really nice. Of course, the best thing to do right now is probably wait until the Surface Pro 4 comes out, but I'd like to see some comparisons with other tablets/hybrid models before I make a purchase decision.

    Since the DELL Venue 8 is now having the option to update to Lollipop, why wasn't it updated before running all the benchmarks?

  • Brandon Chester - Friday, March 13, 2015 - link

    The update wasn't available at the time I was doing my testing. I had to send the Venue 8 back to Dell.
  • LukaP - Friday, March 13, 2015 - link

    Perhaps noting in the review that the Lollipop version is now available, instead of saying it may take a while would be good.
  • Brandon Chester - Friday, March 13, 2015 - link

    I'm actually still looking into this because that hardwarezone source is the only site saying there's now a Lollipop update out, and yet their photos are of a tethered unit running KitKat. Once I hear back from Dell I'll update the article.
