The Chinese tech site, Evolife, acquired a few benchmarks for the Tegra K1. We do not know exactly where they got the system from, but we know that it has 4GB of RAM and 12 GB of storage. Of course, this is the version with four ARM Cortex-A15 cores (not the upcoming, 64-bit version based on Project Denver). On 3DMark Ice Storm Unlimited, it was capable of 25737 points, full system.

You might remember that our tests with an Intel Core i5-3317U (Ivy Bridge), back in September, achieved a score of 25630 on 3DMark Ice Storm. Of course, that was using the built-in Intel HD 4000 graphics, not a discrete solution, but it still kept up for gaming. This makes sense, though. Intel HD 4000 (GT2) graphics has a theoretical performance of 332.8 GFLOPs, while the Tegra K1 is rated at 364.8 GFLOPs. Earlier, we said that its theoretical performance is roughly on par with the GeForce 9600 GT, although the Tegra K1 supports newer APIs.
Of course, Intel has released better solutions with Haswell. Benchmarks show that Iris Pro is able to play Battlefield 4 on High settings, at 720p, with about 30FPS. The HD 4000 only gets about 12 FPS with the same configuration (and ~30 FPS on Low). This is not to compare Intel to NVIDIA's mobile part, but rather compare Tegra K1 to modern, mainstream laptops and desktops. It is getting fairly close, especially with the first wave of K1 tablets entering at the mid-$200 USD MSRP in China.
As a final note...
There was a time where Tim Sweeney, CEO of Epic Games, said that the difference between high-end and low-end PCs "is something like 100x". Scaling a single game between the two performance tiers would be next-to impossible. He noted that ten years earlier, that factor was more "10x".
Now, an original GeForce Titan is about 12x faster than the Tegra K1 and they support the same feature set. In other words, it is easier to develop a game for the PC and high-end tablet than it was to develop an PC game for high-end and low-end machines, back in 2008. PC Gaming is, once again, getting healthier.

Zotac has announced three new ZBOX Nano SKUs that utilize Intel’s 3rd Generation “Ivy Bridge” processors and HD 4000 processor graphics. The new SKUs include base and PLUS models of ID63, ID 64, and ID65 mini PCs.
The tiny PCs continue to use the ZBOX Nano form factor of approximately 5 x 5 x 1.8 inches. The front of the small form factor (SFF) PC holds two USB 2.0 ports, an SD card reader, two audio jacks, LEDs, and a power button. The rear of the ZBOX Nano PCs features an external antenna for Wi-Fi along with the following IO.
- 4 x USB 3.0
- 1 x eSATA
- 1 x HDMI
- 1 x DisplayPort
- 1 x Gigabit Ethernet
The PC comes with a VESA 75/100 mount for wall mounting or attaching to the back of a monitor.
Internal specifications include an Intel Core i3 3227U (dual core at 1.9GHz), Core i5 3337U (dual core at 1.9GHz base, 2.7GHz turbo), or Core i7 3537U (dual core at 2.0GHz base, 3.1GHz turbo) processor depending on the specific SKU. The base barebones ZBOX Nano PCs support a single DDR3 SO-DIMM (up to 8GB 1600MHz) and a single 2.5” hard drive.
Zotac’s ZBOX Nano Plus units bundle in 4GB of DDR3 and a 500GB hard drive. Zotac also includes a “nanoRAID” adapter that will allow users to switch out a traditional 2.5” storage drive for two mSATA drives. The adapter supports RAID 0 and RAID 1 options as well.
Pricing and availability for the new ZBOX Nano SKUs has not been announced yet, but the mini PCs should be up for sale soon.
The decision to release new models with Ivy Bridge processors instead of Intel's latest Haswell CPUs is a bit strange, but the SFF PCs have likely been in the making and testing phase for a while. I expect Haswell-powered versions to be released at some point in the future but for now the Ivy Bridge models will offer up more performance than previous ZBOX Nano units.

Intel recently released an updated graphics driver for Ivy Bridge processors sporting either HD 4000 or HD 2500 GPUs. The new 18.104.22.16871 (or 22.214.171.124.3071 for those running a 64-bit OS) driver features several under-the-hood optimizations to reduce CPU overhead and improve the driver architecture itself.
The driver architecture improvements have also led to improved game performance. Intel claims up to 10% better performance in StarCraft II, Batman: Arkham City, and World of Warcraft: Mists of Pandaria (among others).
The chip giant also notes that the new driver supports OpenCL 1.2 for GPGPU calculations. The graphics driver update is only for Ivy Bridge hardware, and is compatible with Ivy Bridge hardware and both the 32-bit and 64-bit versions of Windows 7 and Windows 8. If you are running Intel's Driver Update Utility, you should get the new driver automatically.
Otherwise, you can grab the new driver from the following link, depending on your OS.
Unfortunately, these drivers are generic Intel HD graphics drivers. If your OEM computer is running Windows with an OEM-customized version of Intel's drivers, you are out of luck. You will need to wait for your OEM to update its driver package in order to take advantage of the performance improvements.
