It's the middle ground between mobile computing and supercomputing
The Consumer Electronics Show (
) 2014 started off with a bang as NVIDIA unveiled a monster chip with 192 cores.
NVIDIA announced its fifth generation Tegra K1 chip, which has 192 CUDA cores and is meant to bridge the gap between Kepler-based desktop cards and the mobile-based Tegra chips. That means one small chip that packs a lot of punch.
The Tegra K1 has a 32-bit
(4-Plus-1 ARM Cortex-A15 CPU) configuration, but another version will support dual Denver CPUs (two 64-bit configurations for up to 2.5GHz).
Other specs include 2.3GHz max clock speed, DDR3L and LPDDR3 memory types, 8 GB max memory size (with 40-bit address extension) and support for 3840x2160 LCD displays.
NVIDIA's CES presentation for Tegra K1 said that it puts a "console in the palm of your hand." A slide showed a side-by-side comparison of the CPU and GPU features of the Xbox 360, PlayStation 3 and Tegra K1.

For GPU features, both the Xbox 360 and PlayStation 3 had support for DirectX 9 while Tegra K1 has support for DX11. GPU horsepower for the Xbox 360 was 240 while PlayStation 3s was 192 and Tegra K1s came in at 365. CPU horsepower was 3600 for Xbox 360, 1200 for PlayStation 3 and 5600 for Tegra K1 all while both the 360 and PS3 used 100W of power and the Tegra K1 came in at only 5W.
The Tegra K1 is expected to benefit a range of areas like lighting systems and photorealism. Some exciting news is that Epic Games is bringing Unreal Engine 4 to the Tegra K1 for a realistic and beautiful gaming experience.
It will be coupled with Android devices, and while NVIDIA didn't specifically mention which ones, it was previewed in many thin, 7-inch tablets.
This is a big win for NVIDIA's Tegra unit, as the company's recent
outlook was a bit gloomy
in that area. In November 2013, when NVIDIA's third quarter earnings report was released for fiscal 2014, many said that NVIDIA's Tegra mobile business was taking development money and margins away from NVIDIA's core PC GPU business (even if Tegra was driving revenue). Analysts even said that spinning off or selling Tegra would allow NVIDIA to become a higher margin company that would continue to return capital to shareholders.
There's no set release date for the Tegra K1, but previous reports have estimated a Q2 2014 timetable.

I'm failing to understand this horsepower thing. X360 has 3600, PS3 has... 1200... of what?
Yes we all know that X360 has 3 cores and PS3 one comparable core... but it also has 7 vector cores in it's Cell processor, which can be utilised to offload both CPU and GPU in PS3.
The article sounds a bit immature, and I'm being extremely diplomatic here...

The whole deal is fishy.
No official approximate release date is a big red flag.
Comparing the latest SoC to those used in an outdated generation of consoles, then claiming how it's better - it's deliberately skewed in Nvidia's favor.
Instead of sitting amongst the bleeding edge of highly mobile graphics performance, the K1 is barely adequate by the time it actually finds design wins - and it is still behind Apple when it comes to actual GPU performance in this generation. Unlike the desktop and laptop GPU lines, the Tegra line has just too many unfulfilled promises.

Seemed like the numbers were meant to be read with lower being better, which makes sense. Puts PS3 at top, then XB360, followed by the K1. So they're just saying this chip puts up a decent amount of processing at 5W that's almost as good as an XB360, but using 1/20th the power.
