Nvidia GeForce RTX 4070 Ti, 40-Series Mobile GPUs and Everything Else It Announced at CES

Your next laptop may have these components. And you’ll probably want them if you create stuff or play games.

Nvidia delivered the first of the notable CES livestreamed announcements Tuesday — a day ahead of the primary marathon day of launches — with expected news about its GeForce 40-series mobile GPUs and the long-rumored RTX 4070 Ti desktop GPU. One notable surprise was the new GeForce Now Ultimate tier, which AT&T has already staked out for a six-months-free promotion. The company also gave some updates on its commercial tools for robotics, collaborative design and cars.

RTX 40-series mobile graphics

Nvidia launched a complete line of mobile GPUs, from the RTX 4050 (for barely-there cheap discrete graphics) to the RTX 4060 and 4070 (for mainstream or thin-and-light gaming and graphics laptops) up through the top-end RTX 4080 and 4090.

Thanks to the Ada Lovelace architecture, the new mobile chips are a lot more power efficient, which means a new generation of Nvidia’s Max-Q power-management technology: It incorporates ultra-low voltage DLSS 3, «tri-speed memory control» to drop to lower power memory states on the fly and more. My experience with the 4080 and 4090 showed quite an improvement in DLSS over the last gen. And finally gaining traction is the adoption of Advanced Optimus, Nvidia’s design for allowing the GPU to live on the same bus as the CPU, which lets you use G-Sync on the built-in display and switch to the integrated graphics for lower power use without a system reboot. (Every time the phrase «MUX Switch» is used, my soul dies a little more.)

It highlighted nongaming 14-inch laptops, such as the Lenovo Yoga Pro 14 and Asus ZenBook Pro 14 with RTX 4070, 4060 or 4050 mobile chips, shipping in late February starting at $999. Gaming laptops like the Alienware x16 with an RTX 4080 or RTX 4090 ship in early February, starting at $2,000.

Desktop GeForce RTX 4070 Ti

Nvidia first announced the 12GB card as a low-end RTX 4080, but people pointed out that its specs really didn’t match those expected of an xx80-class GPU, causing Nvidia to «unlaunch» the card. It’s subsequently been reborn as the RTX 4070 Ti, which starts shipping on Jan. 5, starting at $800.

What seems particularly interesting is that despite Nvidia’s generic renderings of the card, there doesn’t seem to be an Nvidia-branded Founders Edition version, which there usually is for this level of GPU. That means there’s no guarantee that there will be an actual card available at that entry-level price; we could always count on an Nvidia Founders Edition to be the one model that hewed to the announcement price. Even if it had a tendency to go out of stock and stayed that way.

Stay tuned for my review!

GeForce Now Ultimate

Nvidia has also upgraded its back-end cloud servers for its cloud-gaming service with RTX 4080-class GPUs from the RTX 3080-class models, which means its top-tier option for its cloud-gaming service gets an upgrade as well. By going with «Ultimate,» Nvidia doesn’t have to rebrand every time it upgrades, as it does from the previous «RTX 3080» membership.

For the same $20 per month, you get the same perks but the better performance afforded by the card. That can translate to effectively 240 frames per second up from 120fps (the details are unclear). Current RTX 3080 subscribers will automatically transition to the new plan when it becomes available. As usual, it will roll out incrementally across different regions.

You may also get GeForce Now as part of your car’s entertainment system if it uses Nvidia Drive technology. Now all you need is a way to create routes based on the quality of your cell signal to prevent interruptions.

Creator tools

Two notable software tools that run on RTX GPUs join the family. Nvidia Broadcast will get a beta Eye Contact effect — faking eye contact for videoconferences and presentations is the New Big Thing that I don’t like (Windows has it as well). I’ve never seen an implementation that’s not disturbing, and I think at least one of the presenters in the stream was using it because of the unblinking thousand-yard stare that didn’t so much look at you as through you. Maybe that’s just me, though.

The other potentially big feature is RTX Video Super Resolution, designed to improve video streaming on Chrome and Edge. It uses AI upscaling and artifact reduction to improve the look of 1080p video on higher-resolution screens. That will run on RTX 30- and 40-series GPUs.

And Nvidia’s Canvas generative-AI sketch tool, which can work on any RTX GPU, will go into beta this quarter.

Nvidia also provided some updates on its robotics and automotive development technologies. They include new features in its Isaac Sim environment, such as the ability to model multiple humans and arrays of robots (for AI training) and more. CES isn’t a big show for these back-end technologies — that’s more the purview of Nvidia’s designer- and developer-focused GTC and GDC conferences — so most of the news was about partnerships and updates on capabilities entering early access. If that’s what floats your boat, you can get all the details on Nvidia’s site rather than have me de-weed them for you.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color

Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.

Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.

Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.

«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.

Making the case for a caseless color iPhone

I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.

My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.

Pros can be bold, too

Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).

Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.

In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.

And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.

Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.

And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.

Apple never got ahead by being beige

I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.

But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.

Embrace the iPhone colors, Apple.

If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet

Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.

The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea. 

According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.

Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»

K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

More research to do on finding life on K2-18b

The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.

«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»

Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»

The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»

As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.

«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
