The GPU: PowerVR SGX 544MP1

Although the MT8125's quad-core Cortex A7 configuration isn't too unusual, its GPU is. MediaTek integrated a single PowerVR SGX 544MP1 into the MT8125. The MP1 suffix isn't redundant as the MP version of the part includes a last level cache.

The 544MP1 is clocked at 286MHz in the HD7 implementation of the MT8125, yielding peak FP performance of just under 9 GFLOPS. That's nearly 2x the peak FP performance of the Tegra 3 GPU in the Nexus 7, although there's much more to performance than just raw FP throughput.

In practice the MT8125's GPU implementation tends to trail the Tegra 3 based Nexus 7. GFXBench 2.7 shows a 12% reduction in fill rate and less than 1/4 the triangle rate of Tegra 3. The Egypt HD test narrows the gap considerably, but T-Rex HD shows a 32% performance advantage for the Nexus 7 (admittedly at unplayable frame rates from both chips).

3DMark for Android has the Tegra 3 based Nexus 7 ahead by around 12%, while BaseMark X grows that margin to over 40%.

The 3DMark breakdown is quite possibly the most interesting because it actually has the MT8125 pulling ahead in the CPU bound physics test. The GPU-specific test however has the Tegra 3 ahead by 14%.

In terms of real world gaming performance, the MT8125 is honestly fine. I gave Shadowgun and Modern Combat 4 a try, both of which were definitely playable. That's always the big thing to keep in mind with the current crop of game simulation tests under Android: they're mostly designed to stress high end silicon. Game developers on the other hand have to target what the majority of the market has. If we look at stats from Unity around 90% of all platforms are Mali-400, Adreno 2xx, PowerVR SGX 531/540, Tegra 2/3 generation. In other words, at least for the near future the MT8125's GPU performance should be ok.

    Given the MicroSD card slot I would highly consider getting one of these and using it for on the go media, especially for the kids. Reply

    +1 for kids... Especially since this tablet actually outlasts the Nexus 7 in the 3D tests--i.e. gaming. Seems like a pretty well balanced tablet. Reply

    Shame the 8GB model isn't available in the US. >< I would love to have the 8GB model and throw a bigass sdcard in it, then fill it full of movies. Reply

    Hmm, I think the SD card is the only advantage over the Nexus 7! I would just pay the tiny bit extra, for what is one of the best tablets on the market!!!
    Have a look:

    Direct updates by OS vendor Yes vs No It can be updated directly by the OS vendor, so no need to wait until the manufacturer or network provider releases an update.

    Significantly higher pixel density 323 ppi vs 216 ppi 49.54% higher pixel density.

    Reasonably more RAM memory 2 GB vs 1 GB 1 GB more RAM memory.

    Lots narrower 114 mm vs 120.6 mm 6.60 mm narrower.

    Thinner 8.65 mm vs 10.8 mm 2.15 mm thinner.

    Much faster CPU clock speed 4 x 1.5 GHz vs 4 x 1.2 GHz 25% faster CPU clock speed.

    Has NFC Yes vs No Near-field-communication (NFC) allows wireless transactions like payments.

    Wireless charging Yes vs No It can be charged w/o any plugs and wires similar to electric shavers or toothbrushes (as extra).

    my buddy's aunt earned $14958 past week. she been working on the laptop and got a $510900 home. All she did was get blessed and put into action the information leaked on this site... Reply

    Does the MicroSD slot support SDHX? Or in other words: What size of potential memory expansion are we talking about here? Reply

    Found one guy in a forum saying his 64GB SDXC doesn't work, but he didn't elaborate on the file system used or what didn't work. Reply
  • gorskiegangsta - Monday, July 29, 2013 - link

    I believe SDXC cards use the ExFAT format. Reply
  • madmilk - Monday, July 29, 2013 - link

    Maybe exFAT is the most common, but there's nothing stopping you from formatting an SD card as say, ext4. Reply

    64GB Micro-SDXC cards from SanDisk come pre-formatted with exFAT.

    I can attest that they work fine in a Samsung Note 2 and it's widely published on forums that other Samsung devices work fine with these cards.

    The Blackberry Z10, and possibly other BB OS 10 devices, require the card to be reformatted to FAT32. This works fine, except that you are subjected to the 4GB file size limit of FAT32. For most uses this isn't a problem, but if part of your usage scenario is wanting to backup a few large files, in addition to all of the smaller, more typical file sizes that you would normally carry, then the Blackberry isn't the appropriate tool.

    Also, you cannot then swap Micro-SDXC cards between a Blackberry device and a device that uses the more modern exFAT file system. For example, lets say you shot photos and video using a Z10 and saved it on the Micro-SDXC card in the required FAT32 format. You couldn't then put the card into a more modern tablet's Micro-SDXC exFAT enabled slot to display the photos and video to your friends.

    But, if you shoot photos and video on a Samsung device (Note 2, S4, S4 Mini), you could then swap the Micro-SDXC exFAT card over to another device with a Micro-SDXC exFAT enable slot (I believe the Samsung Note 8, Tab 7, and possibly some of the other major name brand soon-to-be-released devices coming out of Asia) to easily display your photos and video to friends and family.

    Many of the smaller devices are shooting 1080P video, but I'm not aware of any 7" or 8" tablet with a Micro-SDXC exFAT enabled slot that has the requisite 1080P screen to display the videos in full resolution once the Micro-SDXC card is swapped over to the larger display device.

    In addition to capacity expansion, I also find it easier to get files in and out of my devices and PCs quickly with the Micro-SDXC cards.

    That is why (for me) it is so frustrating to see Google Asus build such a nice Gen 2 Nexus 7, but leave off the fundamentally important Micro-SDXC slot. My main reason for wanting to replace my Gen 1 Nexus 7 is the lack of a Micro-SDXC slot. The Samsung Note 8 has the slot, but lacks the 1080P display.

    Coming back to the Asus HD7, I realize that it is a budget device and makes no attempt to compete at the high end. The screen isn't 1080P for example. But, until we get devices that universally have Micro-SDXC exFAT enabled slots, we are looking at a fragmented market where devices don't inter-operate that well together.

    It would be interesting to know what the retail incremental cost of a Micro-SDXC exFAT enabled slot is compared to the cost of a Micro-SDHC slot.

    Maybe Asus can't hit their target price on the HD7 with a modern Micro-SDXC slot. Or maybe they are taking a page out of Samsung's book (e.g. S4 Mini) and will under-promise and over-deliver by giving us the more modern slot in the end anyway.
