GeForce RTX 4070 GPU Review: It Hits the Bull’s-Eye of the Middle

From high 1080p gaming to low 4K, as well as for midrange graphics and video production, Nvidia’s RTX 4070 graphics card has got it covered.

Nvidia’s latest throwdown in the GPU arena, the GeForce RTX 4070 seems like the most well-rounded meat-and-potatoes gaming card choice you can get — at least for the moment. It’s a first-rate option for upgrading to high-speed, highest quality 1080p through entry 4K gaming, hitting all of 1440p in between. Covering that much ground means you should be safe for a few years until you’re ready to upgrade again. It’s good for 4K video editing, most streaming and entry-level pro and AI-assisted graphics. The size and power requirements make it a good fit for midsize systems. And starting at $600, it’s the least expensive way to hit all those targets.

The step-up RTX 4070 Ti outperforms it, sometimes by quite a bit, thanks to its faster GPU clock and more cores across the board, which makes the 4070 Ti a tempting competitor for the same gaming performance classes as the RTX 4070. But it’s at least $200 more (although who knows what the 4070’s price range will settle at once the third-party boards start to ship on April 13), recommends a class higher of power supply and takes up more space. Though the 4070 Ti only needs a half-slot more width, that means it will block an entire second slot on many motherboards, and it might not even fit in some smaller systems.

AMD’s RX 7900 XT and RX 7900 XTX also outperform the RTX 4070, but they’re even more expensive than the RTX 4070 Ti and can’t keep up with the RTX 4070 for ray tracing. They’re also 2.5 slots thick like the 4070 Ti. And though it sounds tempting to opt for a last-generation GeForce model, they aren’t really cheaper unless you drop below an RTX 3070. But at that point you’ve also dropped down to a different performance class.

One reason to go for an RTX 40-series class card over an older generation is the jump from DLSS 2 to DLSS 3, Nvidia’s performance optimization technology, that the newer Ada architecture made over Ampere. DLSS 3 delivers significant gains over its predecessor. The downside is that there aren’t a lot of DLSS 3-supporting games out yet — only about 50, which isn’t much out of the universe of thousands of games. But it does bump DLSS 2 performance over the RTX 30-series as well.

It was a bit odd that Nvidia didn’t release a home-grown Founders Edition of the 4070 Ti, but it returned to tradition with the 4070; the Founders Editions are notable for having guaranteed as-launched prices, though they also tend to sell out fast for that reason.

There’s little novel about the RTX 4070 FE’s design relative to the rest of the line. The one notable distinction is the power connector, which like the others needs either the bundled adapter or PCIe 5.0 PSU cables/adapters, but only uses a single 12-pin connection (rather than two).

Like its siblings, the RTX 4070 FE has three DisplayPort 1.4 connections and one HDMI 2.1.

Lori Grunin/CNET

Companies release the highest priced, highest performing model, wait a little while to see how many people snap it up, then release a slightly cheaper, slightly less powerful model, rinse and repeat. And none do it more consistently than Nvidia. That makes offering informed buying advice harder than necessary: We know that slower, cheaper GPU models are coming, but not how much slower or how much cheaper.

I wouldn’t be surprised if there were a 4060 Ti in our future that makes an incremental drop that’s worth the performance sacrifice for the price savings, the way the RTX 4070 did subsequent to my review of the RTX 4070 Ti. But for the moment, the GeForce RTX 4070 seems to strike the best balance of performance for the money, and one that should keep you happy for a few years.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
