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.

have you looked into the Wifi external drives like the seagate goflex? I've been flirting with the idea of putting my 2012 Nexus 7 in the dash of my car as a Nav/media head unit, and think something like the goflex would be perfect to bring all my music with me and not have to fill up the Tablet's storage. It's a bit pricey, but it seems to be a great option.hrrmph - Wednesday, July 31, 2013 - link
Nope... but it has occurred to me that if they equip more smartphones and tablets with Wi-Fi-AC, and improve Wi-Fi interoperability between devices and PCs, then internal storage capacity concerns could be much alleviated, although not completely done away with.Wi-Fi, when implemented properly (as in more reliably and more openly so that devices are easier to be found and recognized), could be a winner on all fronts (storage, communications, etc.).
Unfortunately the only Wi-Fi to PC connection I've been able to get working has been the Samsung Kies Air PC client software. It was kludgey at best, and unworkable most of the time, so I just abandoned using it.
For your nav system, you might have better luck. At least you should have a steady power source from the car's electrical system, and therefore the devices' battery discharge times shouldn't be such a big concern.

The nexus 13 has a hotspot built in. Its fast 300 mgs a min. Es file exployer lets start a ftp server. Thats how I get files on my nexus 13DanNeely - Monday, July 29, 2013 - link
In general the forward/backward compatibility requirements in the SD standard mean that larger than standard SD cards should work (SDHC in SD, and SDXC in SDHC slots). If there's a problem out of the box, it's generally that older devices only understand FAT32 while SDXC cards are formatted as exFAT by the factory. This is easy enough to fix yourself assuming you've got a PC with an SD card reader.Death666Angel - Monday, July 29, 2013 - link
Huh? Since when does the SD standard include backwards forward compatibility of the card readers? I've had plenty of card reads that didn't work with SDHC cards, no matter the file system. If what you are saying was the case, there would be no need for these new standards, as SD card readers would be fine reading up to 32GB and 64GB even.... ? :)hrrmph - Monday, July 29, 2013 - link
SDXC slots can read the modern SDXC cards as well as the older SDHC and SD cards.SDHC slots can read the specified SDHC cards and the classic SD cards.
The older slots (such as SD or SDHC) cannot read cards of a newer, more modern standard (such as SDXC).

I've got a cheap SDHC based mediaplayer (Sansa clip zip) happily reading a 64GB SDXC card that I reformatted as FAT32. A year or two ago when most Android phones with a card slot officially topped out at 32GB SDHC, most if not all of them would take 64GB cards if you downformatted them. Except for an occasional device that had a hardcoded limit and threw a snit they almost universally would read the card at full capacity if you formatted it in a way they understood (at the cost of losing SDXC's higher theoretical speed limits).One ex:

SDXC standard was released before there was wide spread availability of SDXC cards, so most manufacturers said they only support 32GB / SDHC and it was hard for people to test if they supported more. However, just because some of those who said they only are SDHC compatible support SDXC these days does not mean that it is a general rule or that SD reader now support SDHC/SDXC cards as well. And certainly, there is no kind of forward compatibility that is in the SD-standard that I could find. So please don't go about it as if everything supports everything.hrrmph - Monday, July 29, 2013 - link
SD = 2GB maxSDHC = 32GB max
SDXC = 64GB (current) max, although specification allows up to 2TB
Asus official specs say "Micro-SD up to 32G" which would indicate that they have installed the cheaper, older Micro-SDHC capable slot with the 32GB limit.
The only hope for larger cards here is that they are mistakenly listing the 32GB limit when there might actually be a Micro-SDXC capable slot installed. This happened recently with the Blackberry Z10 and the Samsung Note 8 devices. Both were originally slated to be 32GB max, but actually ended up with the higher capacity Micro-SDXC slots which handled 64GB cards just fine.
It would be very helpful if AT would keep a 64GB Micro-SDXC card available and pop one in and see if it gets recognized when they do device reviews.
An even bigger question is, for those devices that have a Micro-SDXC slot (nearly everything Samsung makes), what happens when the 128GB cards become available? Will it be like hard drives where the device will automatically recognize the larger capacity up to the limits of the specification? If so, then having a Micro-SDXC slot would become very important for people who plan to keep and use their devices for a long time.

The SD max is 4GB. I had a 4GB SD card running happily in my original Wii. The 4GB cards were hard to find, but they did work in most older devices.http://www.newegg.com/Product/Product.aspx?Item=N8...
