Nvidia Announces 192-Core Tegra K1 Chips, Bets On Android
sfcrazy writes "Nvidia just announced Tegra K1, its first 192-core processor. NVIDIA CEO Jen-Hsun Huang made the announcement at CES 2014. He also said that Android will be the most important platform for gaming consoles. 'Why wouldn't you want to be open, connected to your TV and have access to your photos, music, gaming. It's just a matter of time before Android disrupts game consoles,' said Huang." Nvidia's marketing department created a crop circle to promote the chip after CEO Jen Hsun Huang declared that it was so advanced that "it's practically built by aliens."
Nvidia's just saying that because they lost the bid for all the consoles.
(It doesn't mean it's not true, though.)

Have to remember that one for the next time I present a design or an engineering proposition to some pointy-haired bosses. Ha !

Completely off-topic and feeding the troll so I'm AC'ing but here in Trondheim, Norway our Christmas Eve was the warmest on record ever. Ever see those nice pressure spirals on TV? Where air flows down on the left-hand side (assuming northern hemisphere) it gets fucking cold, where air flows up on the right-hand side it gets fucking hot. It pretty much evens out for the planet.
I definitely thought the crop circle was manmade, given the design and the reports that said a group of people were in the area. I thought it was more an independent attention-whore art-prank, though; nor did bells go off in my mind that the Braille "192" meant a 192 core processor either (though it obviously was a processor or circuit board by appearance).
You can hold down the "B" button for continuous firing.
... Why would Sony and Microsoft be open? What interest would they have in using a competitor's OS? And creating a completely NEW platform would still be very hard...
The CPU in this has four 32-bit 2.3GHz Cortex A15 cores. A model will come out later with two 64-bit 2.5GHz "Denver" cores -- a CPU of NVidia's own making which they haven't released many details about but their benchmarks show as significantly faster.
When I saw them marketing it as 192 cores I let out a sigh... because these kind of dumb tactics are so expected now.
Well over here in Sweden, we haven't seen such a warm winter in 50 years, there was a tiny dusting of snow in late november, but since then, no snow and frequent above-zero nights. Global warming is *global*, it's the average temperature across the globe, which, believe it or not, is larger than the continental United States or your hometown.
Why didn't they give this the code name Roswell?

It would have been a lot more interesting if it actually was 192 CPU cores in it. Of course it would be a bit of a challenge to code for it - and to get an efficient OS build for it. But on the other hand it's probably the way that we need to go in order to get more performance in the future.

Better be careful with statements like "Practically built by aliens". Nvidia might be getting a visit from immigration control to make sure their aliens are not illegal.
When can I have it in my phone?
32bit so games will be cap about 2.5 gb ram and 1gb video ram?
In the Netherlands, on the other hand, we're currently having the mildest winter I can remember.
It's the first year since I was born some 36 years ago without snow or ice.
Typically, temperature would be well below freezing. Right now it's 14C (57F).

How many more GPU cores are needed until computers can auto-correct apostrophes for illiterates?
the answer, my friend, is blowing in the wind ...
To begin with, the summary and headline are being misleading - that's 192 GPU "cores" (really ALUs - there's only one scheduler on this entire GPU), so it's already inaccurate. But it's also hardly the first Nvidia chip with 192 "cores".
First Tegra with a 192-core GPU, but it's not their first 192-core GPU. Their first was the GeForce 260, followed by the GeForce GTS 450, GTX550 Ti, GT630, and GT635.
In fact, this is basically a GT630 with a smaller memory interface (64-bit LPDDR3 instead of 128-bit DDR3) and a few power optimizations.
The sad thing is, they don't have to make up bullshit for marketing - they're bringing a full-fledged, full-featured GPU to mobile products, with all the modern features that entails. And even with just one SMX at low clocks, that's still a lot of horsepower - I run Crysis at 1080p on high with just two SMX units (660M). Putting that amount of power into a tablet would be impressive on its own, no lying about "cores" necessary.
I was about to ask the potential scrypt mining power of this thing relative to its cost and power requirements and then I realized it's nVidia.
Forget about it.

I was misled too. The useless headline is using the same pointless info nVidia presented, because they can't use "CUDA cores".
32bit so games will be cap about 2.5 gb ram and 1gb video ram?
What phone has more than that?
"First they came for the slanderers and i said nothing."
A 5W chip producing 360 gflops. To put that into persective a GeForce 730M, which has the same architecture, but twice as many cores and rated at 556.8 GFLOPS, is a 33W part.
So basically, Nvidia have made Kepler 4 times more efficient with no architecture changes. What magic did they use?
Sure, why not?
That's considerably more than an xbox 360 or ps3, and people are more than happy to play games on those.

I don't see the original post. Kinda interesting if there never was one. In any case, whatever it's origins, it's a fine example of the use case bigotry genre.
This is the kind of thing frequently heard expressed by a person riding the special-needs short bus—as in, not comprehending the needs of others worth a damn. The longer one lives life the more one realizes that we are all special needs in some dimension, which is why the fascist unification of consumer sentiment sucks ass.
From my perspective, ? what the hell else would you do ? with a $500 television if you subscribe to Telus Optik 50, and you haven't even installed the television modem—as I haven't—because the default content available represents negative value: for every good show one manages to watch, there's an equal amount of cognitive filth to studiously avoid.
Studious avoidance is an expensive activity. Ask any college drop-out. Or read any of the recent science on the will-power muscle, which suggests that the effort expended successfully avoiding the tempting (but awful) TV program is quite likely to show up as inferior decision making later that evening when you juggle your retire savings plan.
I suppose that "Nobody" is just a youthful code word for "Nobody who is anybody" after first screening out the educated, the thoughtful, and the literate in order to better isolate the spending demographic of happening now.
32-bit means only that a single process sees a 32-bit virtual address space. The underlying A15 hardware supports 40-bit physical addresses, so the OS can deal with up to 1TB of RAM, if it wanted to. The only restriction is each process can only see 4GB at a time. The GPU frame-buffer is not mapped into the game processes address space (parts of it may be mapped in to the graphics driver's address space), so your app/game can use 4GB of ram (more or less).
http://www.arm.com/files/downloads/ARMv8_white_paper_v5.pdf talks about the limitiations of this approach and why 64-bit addressing is generally nicer, though
Those 'cores' are far more powerful CPU processors than anything we used in the pre-80486 age. The are NOT usually programmed like a traditional CPU, since such a paradigm would give LOUSY performance (see the world's most disastrous CPU/GPU project- the Larrabee- for a textbook example of why you NEVER EVER simply build loads of what a very very dumb person considers 'proper' cores).
You, PhrostyMcByte, are the kind of cretin that causes the Chinese companies to stuff EIGHT useless CPU cores in their newest ARM SoC parts, just so dribblers can say "DUH- my phone has 8 'proper' cores, duh". Meanwhile, everything that runs on that phone only lights up 2 cores, for power and coding reasons.
It gets worse for the dribblers. The GPU architecture of AMD and Nvidia is actually VASTLY more efficient doing most database operations- sorting, searching, indexing- often operating so quickly that the limiting factor is the speed of the memory itself- and remember the GPU has a VASTLY better memory sub-system than even the most expensive solutions from Intel. It is the DUMB, traditional CPU cores that hold back a modern computer, and it is the smart cores of AMD and Nvidia GPUs that allow levels of performance unthinkable only a few years back.
These are CUDA cores. You can program them.

I dunno, i thought the same until i played FF6 on android. the onscreen controls work surprisingly well (basically emulating an analog joystick via touch). There's no real technical reason that more involved RPG's or games with depth can be created.. Sure anything beyond what you'd find playable on a 8 to 32 bit console might be dicey, but for your standard RPG, the limitation isn't baked into the hardware. It's Similar to the mindset of tablet = content consumption.. the mindset of android game = tower defense/puzzle/casual/whatever nonsense isn't rooted in anything besides lazy app developers taking the lowest common denominator and trying to create the next high volume, low cost time-waster.
I know - but I still would like to see them provided natively by an OS.
