Toshiba Radius Laptop

As many pixels in a notebook would you compress to? The company Toshiba is using the Satellite Radius 12, a 12-inch compact with an optional 4 K touch panel, to check the limitations. But there’s more to it than pixel count: This monitor is more vibrant than most of the other monitors of this scale. Professionals a lot.

Short battery life however seriously restricts the performance of the laptop. Users wanting to swap output pixels can try out the 1080p Radius 12 ($800), which lasts longer on a single charge and has performed well in our evaluations.


The laptop is very handy. The 1080p Radius 12 has a rather close architecture that changes to silver variants of the black shell and table.

As with the rest of the Radius band, the device will spin 360 degrees on this 12-inch Toshiba, enabling you to use it in a tent, stand, and laptop mode as well. The two hinges on the Lenovo Yoga 900 are even simpler than the others — no complicated 500-piece arrangement here — but they perform just fine.

The Radius 12 is heavier at 2,93 pounds than the Dell XPS 13 (2,8 pounds), the Lenovo Yoga 900 (2,8 pounds), the HP EliteBook Folio 1020 (2,68 pounds), the Dell XPS 12 (2,8 pounds), and the 12-inch Retina MacBook (2,03 pounds). None of those notebooks, of course, have screens that can turn back on themselves.

The 11.8 x 8.2 x 0.61-inch Radius 12 is larger than the 12-inch MacBook (11 x 7.7 x 0.14-0.52 inches) and the 12.5-inch XPS 12 (11.46 x 7.8 x 0.63-0.99 inches), roughly the same size as the XPS 13 (11.98 x 7.88 x 0.33-0.6 inches). And lower than the HP EliteBook 1020 (12.2 x 8.27 x 0.62 inches) and the 13.3-inch Yoga 900 (12.75 x 8.86 x 0.59 inches).

There’s no question that the Radius 12’s 4 K panel is one of the greatest I’ve seen on a desktop, and definitely that low on one. This all showed up on the phone. During a 4 K advertisement for Suicide Squad, Jared Leto’s Joker looked uncannily disturbing. I could see every pore and mark and his metal teeth were gleaming. Similarly, in Batman v Superman: Dawn of Justice I could see every raindrop and scrape on Batman’s armor.

Pictures, too, seemed more vibrant on most other notebooks than I have used. The contrast of Gotham Hall’s pictures obviously brought out the features of the walls, and the lights and shadows had vivid blacks and blues. In another BMW image, I could easily distinguish the clear reflections in its white door panel

Given the Lilliputian pixel size of 12.5 inches, Toshiba crammed in quality 4 K (3840 x 2160), rendering it bright and simple. This is far above the HP EliteBook 1020 (12.5 inches, 2560 x 1440), the MacBook (12 inches, 2304 x 1440), the MacBook Pro (13 inches, 2560 x 1600), the Dell XPS 12 (12.5 inches, 1920 x 1080), the Yoga 900 (13.3 inches, 3200 x 1800) and the Dell XPS 13 (13.1 inches, 3200 x 1800).

Of course, we have lacked the information scope shown on the 4 K version of the notebook. Even, a 1080p display would be only right with certain projects.

Going into depth

Toshiba’s assumptions were accurate; we were calculating a 99.8 percent Adobe RGB performance. Usually, we just calculate with the sRGB norm — a somewhat narrower color spectrum. And the Radius 12 has reached 99.9 percent on that. In this test, the Dell XPS 12 panel surmounted all its rivals, showing 114.3 percent of the range.

Even, the Radius 12 gets top scores for accuracy in color. Its result of 0.59 on our Delta-E scale (numbers equal to 0 are better) beats Yoga 900 (2.77), XPS 12 (4.39), XPS 13 (5.1), Folio (7.4), and also MacBook (1.2) by a broad margin. If you choose for the 1080p Radius 12, assume less reliable color since it won just 2.79 Delta-E ranking.

With an overall brightness of 338 nits as calculated by our light meter, and stopped only shy of the 12-inch MacBook (353 nits) and the 1080p Radius 12 (369 nits). The Dell XPS 12 is lighter than all five of those journals, with 413 nits of light.


On the Radius two downward-facing speakers produced decent, but not great, performance.


Toshiba has done a fairly good job of fitting in a keyboard for such a small laptop, which maximizes its volume.

I wish the keys were still somewhat concave and the arrow keys were wider. On my normal laptop keyboard, I find myself making more mistakes than I expected.


The Radius 12’s left side has a full-size HDMI socket, a USB 3.0 socket, and a Type-C USB 3.1 Port. The right side includes one more USB 3.0 outlet, an SD card tray, a power switch, a volume slider and a Cortana switch for when you’re using the Radius 12 in laptop mode, in another helpful change. The click was rigid enough to discourage you from unintentionally turning it on.

With an Intel 2.5-GHz Core i7-6500U processor of 6th generation, 8 GB of RAM, and 256 GB of SSD, the Radius 12’s 4 K setup was expert at everything I put in it. The 1080p Radius 12 we reviewed had a 2.3-GHz Core i5-6200U CPU, 8 GB RAM which 256 GB SSD, which, while having a marginally slower CPU, managed to notch better scores than its more powerful and pixel rich twin. The one with a lower resolution actually scored higher, because it had to move fewer pixels.

The 4 K Radius 12 rated 5,779 on Geekbench, while its sister 1080p rated an even better 6,258. The Core i5 processor and flash memory of the MacBook Pro, however, reached a far higher 7,113, and the Core i7-6500U-powered Yoga 900 received a 6,264.

In OpenOffice, it took the 4 K Radius 12 19.7 seconds to open a 69 MB Word folder.

They were able to downscale a 205 MB, 1080p video to 720p in 1 minute and 41 seconds utilizing Adobe Premiere Components. That’s a couple of seconds slower than the XPS 13 (1:34; Intel HD Graphics 5500) but still quicker than the Intel Iris 6100 Graphics 13-inch MacBook Pro (early 2015) — and it took 3 minutes and 14 seconds.

Look elsewhere, however, if you intend on playing on this notebook. But then, they just managed 27 fps.

The MacBook notched 27 fps at a resolution of 1280 x 800 and the MacBook Pro reached 43 fps at the same settings. The XPS 13 while set to Nice reached 35 fps at 1080p.

In this study, the 1080p Radius (798) did worse than the 4 K edition but still defeated those two competitors.

Battery Life

Notebooks with 4 K screens, naturally, use far more resources than those with lower resolution panels. We’ve seen that with the Dell XPS 13 — an XPS variant with a 1080p monitor lasted 11 hours and 42 minutes.

But the 4 K Radius 12 comes way short even on those parameters. Even though Toshiba claims the notebook will last up to 6.5 hours, the 4 K Radius 12 lasted only 5 hours and 17 minutes on the Laptop Mag Battery Check (Web browsing via Wi-Fi).

The 1080p variant performed much better. The MacBook Pro 13-inch monitor with Retina lasted an incredible 12:04 period.

We have checked two Radius 12 models, one with a 4 K monitor and the other with a 1080p panel. The 4 K variant is the high-end Radius 12 version that costs $1.299 and comes with a 2.5-GHz Intel Core i7-6500U CPU, 8 GB of RAM, and 256 GB of SSD.


Toshiba holds a fairly light on the Radius 12 device load.

709, Universal & Photoshop RGB. You may also customize the feature to alter profiles automatically based on the device you are using — for example Adobe RGB with Photoshop, and Technicolor with Premiere. I really wish you could build a profile of yourself.

No doubt Toshiba put a ton of the Radius 12 into a little box. The laptop’s 4 K edition has a beautiful monitor and decent performance. And it fits all of that into a compact that weighs just under 3 pounds. Although the 1080p Radius 12 does not have a screen as amazing, the additional battery life allows it more convenient for someone who spends time away from a computer.

While we like his screen a lot, because of its terrible battery life we can not suggest the 4 K edition of the Radius 12. And much greater durability the 1080p version is certainly worth considering. If you don’t need a 2-in-1, the 12-inch MacBook helps you to have even longer endurance. The Dell XPS 12 has lower durability among 2-in-1s but provides a better keyboard and a stylus. But if you want a solid, 2-in-1 bend-back at a good price, the Satellite Radius 12 base model is a great option.
