Have you ever wondered how a mobile GPU is born? Or how the architecture of a mobile GPU like ARM Mali differs from the technology in your discrete PC graphics card? Perhaps you just want to know if ideas like HBM (high bandwidth memory) are going to find their way into the mobile ecosystem any time soon?

Josh and I sat down (virtually) with ARM's VP of Technology and Fellow, Jem Davies,  to answer these questions and quite a bit more. The resulting interview will shed light on the design process of a mobile GPU, how you get the most out of an SoC that measures power by the milliwatt, what the world of mobile benchmarking needs to do to clean up its act and quite a bit more. 

You'd be hard pressed to find a better way to spend the next hour of your day as you will without a doubt walk away more informed about the world of smartphones, tablets and GPUs.

Introduction and Specifications

Displays have been a hot item as of late here at PC Perspective. Today we are looking at the new Acer XB270HU. In short, this is an IPS version of the ASUS ROG Swift. For the long version, it is a 1440P, 144Hz, G-Sync enabled 27 inch display. This is the first G-Sync display released with an IPS panel, which is what makes this release such a big deal. Acer has been pushing hard on the display front, with recent releases of the following variable refresh capable displays:

  • XB270H 27in 1080P 144Hz G-Sync
  • XB280HK 28in 4K 60Hz G-SYnc
  • XG270HU 27in 1440P 40-144Hz FreeSync
  • XB270HU 27in 1440P 144Hz G-Sync < you are here

The last entry in that list is the subject of todays review, and it should look familiar to those who have been tracking Acer's previous G-Sync display releases:

Here's our video overview of this new display. I encourage you to flip through the review as there are more comparison pictures and information to go along.

Or: How to fall asleep at work.

I will be the first to admit that just a couple of weeks ago I had zero need for a gaming chair. But when 4GamerGear.com offered to send us one of the AKracing AK-6014 ergonomic executive units, I agreed. I went out of town for a week and returned to find the chair assembled and already in use by Ken, our go to video editor and engineer. Of course I had to steal it from him to take part in the "review" process and the results were great! As I sit here now in my Ikea office chair, writing up this post, while Ken sits just feet away tapping away on some edits, I can't help but want to use my authority to take it back.

The price is steep, but the added comfort you get from a chair like the AKracing model we tested is substantial. Every part of the design, based on a racing seat for a car, is built to keep you in place. But instead of preventing lateral movements caused from taking corners, this is more to keep your butt in place and your back straight to encourage good posture. The arm rests are height adjustable (as is the seat itself of course) and the back reclines for different desk and resting positions. You can lay it PAST flat for naps if you're into that kind of thing.

You can find these chairs for sale on Amazon in different color combinations with a current price of $349. It's expensive, I can't deny that. But it looks and feels way cooler than what you are sitting in right now. And aren't you worth it?

Some familiar scenery

If you thought that Intel was going to slow down on its iteration in the SFF (small form factor) system design, you were sadly mistaken. It was February when Intel first sent us a NUC based on Broadwell, an iterative upgrade over a couple of generations for this very small platform, 4" x 4", that showed proved to be interesting from a technology stand point but didn't shift expectations of the puck-sized PC business.

Today we are looking at yet another NUC, also using a Broadwell processor, though this time the CPU is running quite a bit faster, with Intel Iris 6100 graphics and a noticeably higher TDP. The Core i7-5557U is still a dual-core / HyperThreaded processor but it increases base and Turbo clocks by wide margins, offering as much as 35% better CPU performance and mainstream gaming performance boosts in the same range. This doesn't mean the NUC 5i7RYH will overtake your custom built desktop but it does make it a lot more palatable for everyday PC users.

Oh, and we have an NVMe PCI Express SSD inside this beast as well. (Waaaaaa??)

Don't be afraid of PCIe or NVMe

In very early April, Intel put a shot across the bow of the storage world with the release of the SSD 750 Series of storage devices. Using the PCI Express bus but taking advantage of the new NVMe (Non-Volatile Memory Express) protocol, it drastically upgrades the capabilities of storage within modern PC platforms. In Allyn's review, for example, we saw read data transfer rates cross into the 2.6 GB/s range in sequential workloads and write rates over 1.2 GB/s sequentially. Even more impressive is the random I/O performance where the SSD 750 is literally 2x the speed of previous PCIe SSD options.

A couple of weeks later we posted a story looking into the compatibility of the SSD 750 with different motherboards and chipsets. We found that booting from the SSD 750 Series products is indeed going to require specific motherboards and platforms simply due to the "new-ness" of the NVMe protocol. Officially, Intel is only going to support Z97 and X99 chipsets today but obviously you can expect all future chipsets to have proper NVMe integration. We did find a couple of outliers that allowed for bootability with the SSD 750, but I wouldn't count on it.

Assuming you have a Z97/X99 motherboard that properly supports NVMe drives, of which ASUS, MSI and Gigabyte seem to be on top of, what are the steps and processes necessary to get your system up and running on the Intel SSD 750? As it turns out, it's incredibly simple.

Step 1

Make sure you have enabled NVMe in the latest BIOS/UEFI. The screenshot below shows our ASUS X99-Deluxe motherboard used during testing and that it is properly recognizing the device. There was no specific option to ENABLED NVMe here though we have seen instances where that is required.
