Nvidia Tegra K1 Benchmarks from Lenovo ThinkVision 28

One of the more unique products at CES 2014 was Lenovos ThinkVision 28. Positioned as a 4K (3840x2160) 28 LCD pro monitor, which happ

to also run Android, the ThinkVision 28 w ill be available in July, starting at $1000. The ThinkVision 28 is part of the PC P lus movement, and while

marketed primarily as a display (hence the ThinkVision moniker), this is a full system here, folks.

This monitor features Android 4.3, Nvidias Tegra K1 SoC, 2 GB DDR3, 32 GB eMMC storage, a microSD slot, three USB 3.0 ports, one USB 2.0 po

one microUSB 3.0 port, audio in/out, speakers, mics, webcam, Ethernet, W i-Fi, Bluetooth 4.0, NFC, Miracast, three HDMI ports, one DisplayPort, a

a 10-point touchscreen.

The key aspect is, of course, the display. Its 2160p Ultra HD. 4K is cool right now . Everyone wants 4K. But what were really interes ted in today

what powers the ThinkVision 28: Nvidias new Tegra K1 SoC.

While Lenovo didn't explicitly confirm or deny the SoCs inclusion in its ThinkVision 28 display, knowing w inks and smiles were the order of the da

when the question came up. CPU-Z just reports the SoC as Tegra 2, which is possibly a holdover from Lenovos old Tegra 2-based K1 tablet

little irony in itself.

2/4

The ThinkVision 28s Tegra K1 contains four ARM Cortex-A15 CPU cores reported to run at 2 GHz, plus one low speed companion core likely

operating at 500 MHz (as with Tegra 3 and 4), and a Kepler-based graphics engine with one SMX unit consisting of 192 CUDA cores. We weren't

able to pull the GPU's clock rate, but we suspect it's lower than the ~950 MHz guessed by Angelini in his preview of the AP.

Interestingly, Nvidia says the K1 can run at up to 2.3 GHz, so it's poss ible that either CPU-Z isn't recognizing the SoC's frequency yet or Lenovo

running the application processor around 15% below its ceiling. Lets see how it fares in some benchmarks.

Since people are going to be most interested in the 192-core Kepler GPU, our tests w ill focus primarily on graphics.

3DMark

3DMark is a multi-platform graphics benchmark that contains both graphics and physics tests. The Unlimited version runs at an off-screen resolut

of 720p, allowing for chip-to-chip comparisons , rather than forcing us to take each device's panel into consideration, too.

3/4

Based on our initial look at Tegra K1 in Lenovo's ThinkVision, the SoC far outperforms any of its competition, post ing 25%-higher results in the G

heavy graphics workload and CPU-limited physics test.

If the Tegra K1 is indeed operating at a lower-than-peak clock rate, that might explain the s light performance bump from EVGA's Tegra 4-based

Tegra Note 7, which also features four Cortex-A15 cores based on a previous revision. Still, at almost 15% faster than the Qua lcomm's Snapdrag

800 (at 2.26 GHz), the Tegra K1 still fares rea lly we ll against Krait. With Snapdragon 805 now on the horizon, it'll be interesting to see how thes

results are affected by even higher frequencies.

GFXBench

This multi-platform test renders a scene whe re a lot of effects interplay along w ith some physics and add itive lighting. Off-screen is tested at

1920x1080, while on-screen relies on the display's native resolution. Although GFXBench 3.0 is now available, 2.7 was the version installed on t

ThinkVision 28 floor model.

In the off-screen test, Tegra K1 comfortably takes the lead over Apple's A7 (by almost double)! Qualcomms Snapdragon 800 and Nvidias Tegra

are in third and fourth place respectively, scoring within 10% of one another.


4/4

The on-screen test te lls a different s tory, since display reso lution has as much impact as raw GPU power. Nvidia's Tegra K1 suffers under the

demands o f Lenovos UHD panel, slipping from first place in the off-screen test to last p lace in this benchmark. Both sub-FHD devices, the Apple

iPhone 5s and EVGA Tegra Note 7, eas ily take first and second place. Googles Nexus 5 is also punished for its 1080p display, but still manages t

render an almost-playable 24 frames per second.

AnTuTu

AnTuTu is more of a general system benchmark, where almost every aspect is either derived from or directly affected by CPU core performance. A

such, we felt it necessary to include the result, even if only to indicate the expected performance of the Tegra K1 when clocked below peak

performance.

Interestingly, the Tegra K1 wins the UX tes t by a s ignificant margin of roughly 5%, even though its driving a 4K display in the Lenovo ThinkVision

28. However, it is poss ible that Android 4.3s full HWCOMPOSE support is offering bette r UI performance than the Tegra Notes Android 4.2. In an

case, the EVGAs Tegra 4 beats both the Nexus 5s Snapdragon 800 and the potentially underclocked Nvidia Tegra K1.

Potentially The Next Big Thing In SoCs

While were still in the very early days of Nvidias Tegra K1 (and 4K displays for that matter), the immediate results do indeed seem promising. If

real-world performance in any way matches what we see in these few benchmarks, the K1s 192-core Kepler-based GPU could prove to be a gam

changer for mobile graphics, driving high detail levels in content previously only seen on the PC and consoles .

And thats w ithout benchmarking Denver, where ARMv8 could offer even more performance. Next level, indeed.
