Alleged leak of Nvidia's Tegra 4 shows 72 graphics cores

Nvidia's mobile future might have been leaked yesterday on a Chinese forum site.

A user going by the name "Xenomorph" yesterday republished an image shared on China's Twitter equivalent Weibo, detailing what could be the mobile processor that Nvidia launches to replace the Tegra 3. And for now, it's being called "Wayne."

According to the image, Wayne, which might eventually be renamed Tegra 4, comes with Nvidia's 4-Plus-1 technology, meaning the chipset will have four regular cores and another low-power core designed to save battery life. That CPU is described as a &… Read more

MediaTek joins Samsung, Nvidia quad-core club

MediaTek will take on Samsung and Nvidia in the emerging market for mobile quad-core chips.

The Hsinchu, Taiwan-based company today announced the MT6589, a quad-core system-on-a-chip (SoC) that integrates a modem supporting HSPA+ and other international standards.

Integration of a modem into a quad-core chip is a first, the company says.

The processor is based on ARM's Cortex-A7 design, the same technology used in Qualcomm's upcoming quad-core S4 processors.

But that Qualcomm chip won't be available commercially until well into next year. The MediaTek chip, on the other hand, will appear in smartphones that are expected to … Read more

Beyond quad-core: What's next for mobile processing power

Remember when a quad-core processor was the ultimate indicator of a super-smartphone? Well its 15 minutes are almost up.

Just as the current run of super-smartphones are destined for the bargain bin in a few months, so too will the novelty and obsession with the number of cores powering a phone begin to fade. Sure, smartphones with the latest quad-core chips still rule now, but companies are already preparing to change the conversation.

In its place, expect chip companies, handset manufacturers, and wireless carriers to shift their marketing away from an emphasis cores and more toward tangible benefits such as … Read more

Nvidia still has a lot to prove in the mobile market

Nvidia may be flying high on its tablet wins, but it still has a long way to go before it can call itself a real mobile player.

The Santa Clara, Calif., company, traditionally known for making graphics processing units found in computers and game consoles, has been counting on its Tegra mobile chip to help offset weakness in its core PC market. So far, it hasn't been enough. Nvidia is showing up in many tablets, but its presence in smartphones is minimal. In addition, the bulk of Tegra sales are for a couple of tablets, the Google Nexus 7 … Read more

Nvidia CEO: People buying tablets instead of cheap PCs

Tablets really are replacing PCs now that the latest version of Windows has launched, graphics- and mobile-chip maker Nvidia said.

But at least right now, Nvidia's mobile business isn't big enough to offset the less-than-merry computer market this holiday season.

It's not exactly shocking that tablets have been eating into sales of PCs. Computer makers have noted the trend, and so have Nvidia chip rivals Intel and Advanced Micro Devices.

But what's interesting is that Nvidia says consumers now realize that a "great tablet is better than a cheap PC." That could signal a … Read more

The Ouya debate: Who really wants indie gaming hardware?

Upstart indie game company Ouya has made serious waves with its self-titled game console. The under-development system wants to be an open gaming platform, built around freemium games running on Nvidia's Tegra3 platform. According to the project's popular Kickstarter page, the Ouya will cost $99, but won't be ready until at least March 2013.

Despite the hype, however, there are some serious questions about whether the game industry can support another living room console, and whether gamers are looking for more set-top boxes to plug into their TVs.

Nvidia pushes new standard for wireless streaming

Chances are, if you're looking for a way to get the photos, video, or games from your phone to show up on your big screen TV, you've got a wire involved. Chipmaker Nvidia announced today that it's one step closer to having its smartphones and tablets wirelessly share content through a forthcoming standard called Miracast.

Miracast relies on a direct Wi-Fi connection to kick off communication between the devices. Similar to Apple's AirPlay, you don't need to log on to a typical Wi-Fi network.

The Wi-Fi Alliance, of which Nvidia and many others are a … Read more

Microsoft Surface tablet, iPad spec check

Microsoft did not skimp on specs for its new tablets.

More than any single feature, the 3mm-thick Touch Cover (see photos below) stands out. Using pressure-sensitive technology, Touch Cover senses keystrokes as gestures, allowing faster touch typing than is possible with on-screen keyboards, Microsoft claims.

The Touch Cover attaches to the tablet with a built-in magnetic connector, "forming a natural spine like you find on a book, and works as a protective cover," Microsoft said.

There is also an option for a slightly thicker 5 mm Type Cover that adds moving keys for a more traditional typing experience. … Read more

Optimus 4X HD review: Our favorite LG phone yet

Recently, I haven't been so impressed with a string of LG phones. Though a lot of them are good, solid handsets, none of them have wowed me.

That is, until now.

I mentioned the LG Optimus 4X HD back in February, when it was going by the name LG X3. It was rumored to have a quad-core CPU and I'm glad the rumors were true.

Its 1.5GHz Tegra 3 quad-core processor from Nvidia makes it impressively snappy. Not only does it launch and quit graphics-heavy gaming apps like nobody's business, but the 8-megapixel camera is stupid … Read more
