NVIDIA Tegra Architecture

Imagine how super efficient Tegra Parker will be over Tegra K1 Logan.
 
Aside from NV30 and Fermi, when did they not deliver? AMD is notorious for over promising on performance and under performing. Titan Killer Anyone? Or how about Bulldozer? Steamroller? How bout 290x retail cards being slower than review cards? FX Processors? Or rebranding Fusion to HSA to fool consumers into thinking it's all new and different.
And this is only in recent years. I don't feel like going back into the ATi days with drivers that cheated on 3dmark, cut corners doing AA and AF, etc.
And don't get me wrong, nV has had their share of problems, but nowhere near as much of a track record of promising the world only to leave the fanboys in complete disappointment.

I'm replying to the troll because I can see it at the top of the page each time.
One good reason for renaming FSA to HSA is that their "virtual assembly" code is named HSAIL (HSA Intermediate Language), and "FSAIL" would have been very bad (just shift one letter around). "Heterogeneous" is also better than "Fusion" as it invites 3rd party to the table rather than just relate to AMD CPU + AMD GPU.
And Geforce 6/7 has crap texture filtering, though better of that from Radeon 8500/9000.
 
Come to think of it I apologize, let's do Parker or any design past that instead of dealing with the above crap.
 
The Verge says the LG G2 Mini will have a version with Tegra 4i (but their source doesn't mention any SoC whatsoever..):

The G2 mini compromises in two key areas, eschewing the excellent Snapdragon 800 processor for a choice between Snapdragon 400 or Nvidia Tegra 4i chips, and dropping to a disappointing qHD (540 x 960) screen resolution. Further cost-cutting options are also available, such as a lower-res 8-megapixel camera and non-LTE variants. At least the software on board will be the latest available, Android 4.4 KitKat, and LG promises to carry over its full suite of added features, such as Guest Mode, to the new phone.


Another thing that doesn't add up is that the choice between Tegra 4i and a Snapdragon 400. At least according to the specs, the Tegra 4i should have a performance similar to the much more powerful Snapdragon 600. The Snapdragon has, at best, a quad-core Cortex A7 @ 1.6GHz, while the T4i has a quad-core Cortex A9 up to 2.3GHz.

I'm not sure they're saying that there will be two versions available, merely that LG could pick the S400 just as they might go for T4i.
 
I'm not sure about there being a Tegra 4i option. I can't find their source for that bit of information at least. The link at the bottom of their article only mentions a 1.2 GHz quad core processor, not even if it's a Snapdragon or Tegra, but if you then go to their spec page it only mentions a Snapdragon 400. I guess we'll have to wait for some kind of official press release from LG.

German heise.de above claims a frequency of 1.2GHz for the quad A9(R4) *yawn* if true.
 
We can all agree that if those clock speeds are correct, it's not a Tegra 4i.
There's probably something wrong with the Verge's article.

Nonetheless, models with the Tegra 4i should be announced within a few weeks during MWC.

A 1.2 GHz A9(R4) should easily outperform a Snapdragon 400 at 1.2 and even 1.6 GHz. On a Hpm process at low clock speeds, perhaps T4i matches the s400 in power consumption as well? Of course the T4i will have a much larger die size, but if Nvidia wants to price it at S400 levels, then only they suffer not the OEM.

Most likely yes. By the way did anyone read at BSN Carmack's latest comment over K1?

They should have included all the pertinent tweets from Mr Carmack

"Difference is how much the platform gets between you and the hardware, and, in the case of mobile, power and thermal limits"

"For the same given paper spec, a console will deliver twice the perf of a PC, and a PC will deliver twice the perf of a mobile part."

Not so much a critique of the hardware, more Nvidia's terrier-level excitable PR machine:LOL:
 
Which doesn't change anything for the grain of salts comment and its weight. In all fairness it wasn't NV that started those marketing console comparisons. Most of us know where marketing exaggerates and what reality looks like. I don't think though Carmack's comments are for those folks.

That quote was made back when Carmack was still using DX9 for RAGE. Perhaps when it comes to CPU performance and system memory usage that's the case (if we completely ignore mantle and other API improvements since DX9) but for pure GPU throughput most benchmarks show PC's and consoles to be pretty much level pegging for any given GPU spec.
 
Tegra 4 is last year's part and they're trying to get it on this year's devices?

When are the K1 devices due?

According to NV in the first half of this year and in the second half of the year the same SoC but with their custom Denver CPU cores.
