The Tech Report writes evidence is mounting that NVIDIA is working on a 7" tablet. Some details about the Tegra Tab P1640 appeared on the website of the National Certification Commission, an organization which appears to be the Taiwanese equivalent of the US FCC.
According to the blog post, the screen has a 1280x768 display resolution. The resulting 213 PPI might have been impressive last year, but Google has since updated the Nexus 7 with a 1920x1200 display that delivers a much crisper 323 PPI for the same $230 asking price as the original tablet. Even budget slates like Asus' $149 MeMO Pad HD7 can compete with the Tegra Tab's purported pixel density, which makes me wonder how much Nvidia might charge for the thing.
Despite its seemingly pedestrian display, the Tegra Tab should have potent hardware under the hood. The leaked specifications reveal a Tegra 4 SoC clocked at 1.8GHz. They also list front and rear cameras, 802.11n Wi-Fi, Bluetooth, and Android 4.2.2. USB and HDMI connectivity are included, too. Sadly, there's no mention of an SD slot. Although a SIM tray apparently graces the system, I don't see any mention of cellular broadband support—the sort of thing you'd expect a communications certification body to discuss.
