NVIDIA's next-gen X1 mobile chipset: a closer look at the numbers

Earlier tonight, NVIDIA’s Jen-Hsun Huang formally pulled again the curtain on the Tegra X1 — a subsequent-era cellular powerhouse of a chipset that is additionally the primary to proffer a teraflop of processing energy. It should play an important position within the firm’s automotive future, however the cellular nerds studying this is perhaps a bit of extra fascinated about how briskly the X1’s going to make our devices. Fortunately, NVIDIA pulled us apart for a quick-and-livid benchmarking session that gave us a greater concept of what to anticipate when X1s begin trickling into the wild.

First although, a fast observe concerning the check setup: NVIDIA had a handful of octa-core X1 reference boards with 4GB of RAM put in pill-class heatsinks slapped onto them (an NVIDIA spokesperson stated the setup was primarily what you’d stated in an eight-inch X1-powered pill). As Huang famous on stage, the X1 chipset additionally packs the 256-core Maxwell GPU; that is up from the 192 final yr’s K1 one got here loaded with. Alas, NVIDIA would not affirm how briskly the processor cores themselves have been clocked. C’est la vie, pals.

Anyway, take a peek on the numbers the X1 put up. The place relevant, we have included scores from the Nexus 9 and the NVIDIA Defend pill, which run the sixty four-bit and 32-bit variations of the Tegra K1, respectively.

NVIDIA X1 Reference
Google Nexus 9
NVIDIA Defend pill iPad Air 2 AndEBench-Professional 12,401 12,04710,363 N/A 3DMark IS Limitless forty three,769 24,256 30,970 21,659 GFXBench three.zero Manhattan Offscreen (fps) sixty five 31 31 32.four CF-Bench N/A 31,695 forty three,033 N/A

See these two AndEBench values in italics? We did not have a Nexus 9 or a Defend Pill available to check, so we used median values offered by the app’s maker, the Embedded Microprocessor Benchmark Consortium. The X1 pulls forward of each its predecessors within the check, if solely simply (we’ll replace this submit after we run our personal exams on the right hardware). The X1 is not any slouch at video, because it helps 4K video decoding at 60 frames per second — it dealt with playback of a video shot from a RED digital camera with no single hiccup, simply in time for all the large content material suppliers to, properly, go massive on extremely excessive-def video.

Maxwell’s energy is plain, too: The X1 completely spanked all comers (typically by over an element of two) within the extra graphically concerned checks, a testomony to the power of its future as a recreation platform. Whereas we’re with reference to gaming, NVIDIA additionally confirmed that the X1 will play good with an entire host of APIs utilized in recreation improvement, because it has the identical Maxwell structure as its excessive-finish GTX 980 desktop graphics card.In an ideal world, that’ll make for simpler ports and fewer hectic recreation translations from extra conventional platforms like PCs and consoles to cellular ones.

And the icing on this slice of silicon cake? The X1 is designed to sip (relatively than gulp) your gadget’s energy reserves. In a single notably concerned check, the NVIDIA staff measured the voltage utilization charges of the X1 versus the iPad Air 2… after tearing aside eight of them and downclocking the X1 so each have been at an equal degree of efficiency. In the long run, common energy consumption for the Air 2 was 2.6 watts, versus 1.5 watts for the X1, a reasonably vital energy financial savings. It is nonetheless early days for the X1, and all the above has been only a style of what we will anticipate when X1-powered units hit later this yr.
