Any independent test of nVidia Elemental Accelerator?
http://newsletters.creativecow.net/s...-21/index.html
nVidia claims a 500-1100% speed increase using their Elemental Accelerator with a Quadro FX card. Does anyone have a copy coming who would volunteer to share some independent tests?

@Chengbin, does your post seem as silly as it does to me. The card is for speed and is 1/5 or less the price of the equivalent processing done on PCs.
You've heard of "apples and oranges"? Your statement is comparing a car to an airplane. @aegisofrime, decoding is probably the same but methinks it's more likely the "gaming" cards are crippled versions of the same core. I've still got a circuit trace repair pen from when the AMD chips were found to be hackable by connecting surface poles.

500-1100% faster than what, Quicktime?
Seriously, these numbers are meaningless. Last time I saw similar claims, the encoder was actually slower than x264, but they just picked the slowest encoder out there to compare it with.I already have a CPU. It cost $0, because I already have it. If I buy a Quadro, I'm buying something I didn't already have. Even if it actually were significantly faster than x264 (which I highly doubt), it's outright lying to say that it's "cheaper". |

Chengbin totally missed that the primary thesis is speed, clearly shown by the statement,

Claim is ~$700 to have 500% the encoding power of a quad-core system. The same processing power in the equivalent time would require 5 additional quad-core systems at $140 each, far below their actual cost. Even so, the power, complexity and physical space required would be greater, all of which add to TCO. You should chose your words better and read for comprehension. This thread is about nVidia's claim and their products, not your personal situation. I most certainly did not lie but you most certainly did slander me. Keep your straw dog to yourself.

I suggest you stop believing every word that comes out of corporate marketing departments. Quote:
This is ridiculous--my claim that nVidia is lying about it being "cheaper" is slander? I mean, even if my claim was false, which it isn't, you should probably look up the definition of the word "slander" before you use it incorrectly. Furthermore, I don't see any reason you should be standing up for nVidia here and trying to protect them from my "slander" of them. If they want to accuse me of "slander", let them do it themselves.

What about this marketing done by Ati on their launch yesterday ?

Or the abillity to do 1 clock FFT transformations ? |

The main problem with a fast SAD is that it makes the other parts of the motion estimation process a much larger bottleneck than before. (This definitely makes motion search on the GPU a bigger option for x264, but there is still the problem that the analysis we've done on the process suggests that it will be very difficult to fully parallelize the process. It's only easy to parallelize if we do it on the source frames instead of the reconstructed frames... which vastly reduces compression.)

I will no longer reply to you regarding this. It is clear you are not thinking clearly now.

Before this implementation intop DX11, GPGPU had the feeling like good old DOS, where you had to write your game for every graphic chipset separately (Tseng Labs, Ati Mach64, you needed to put drivers for too many of them). Unifying GPGPU in DX11 might help to get things going finally, maybe it also forces Nv to be more open about the assembly instructions used/needed And in that respect it might me a nice idea to put some time/research/brainstorming into Last edited by G_M_C; 24th September 2009 at 10:05. |

You probably should have done that before, not after, repeatedly violating the forum rules. It's quite apparent that you are not actually interested in a technical discussion despite my attempts to respond with technically-oriented posts in this thread.
At this point it is quite clear that you are here to promote nVidia products; you practically admitted it when you took offense after I called nVidia's claims a lie. Only a shill takes personal offense to claims directed against a corporation. Also, slander is spoken, libel is written.

It's not just the final codec that's accelerated, it's the whole pipeline, including decoding and heavy filtering. However, Premier has had gpu-assisted rendering for a decade now, that's nothing new, and completely turning it off is very disingenuous. However, there's nothing to prove or disprove, the entire claim is pure marketing: There's no hard facts, and plenty of room for people to read in their own ideas.
There is one useful chart: But how high is the quality compared to Adobe's high quality preset? Nobody knows, that's not included; they'd just like you to believe they're equivalent. Again, it's regular marketing. Fred, your hypersensitivity is borderline trolling. Calm down before you are struck. |

Here's another brief mention translated from German which says nVidia was claiming 2-11 fold increase earlier this year: http://www.slashcam.com/news/single/...erat-7701.html

2-11 fold the speed of a quadcore CPU is clearer ... GPGPU is supposed to be faster than that isn't it ? 2 x speed of nehalem, upcoming Sandy Bridge will probably be 2 x faster than Nehalem too (and it might be 11 times faster than AMD's slowest X4). Let Nv and Ati get SAD (and other usefull commands) into OpenCL first, so that everybody can use it; And not only those who can shell out for some exotic piece of hardware, and some equally expensive piece of software that can use it. As long as it remains that much of a niche-product, almost nobody will actually care. Last edited by G_M_C; 24th September 2009 at 15:08. |

Here's some previous discussion on the NVIDIA CUDA encoder: http://forum.doom9.org/showthread.php?t=148276 Elemental accelerator may use a completely different encoder implementation, so until we see proper tests... Edit: Information on the encoder parameters can be found in the user guide: http://www.elementaltechnologies.com...20Guide-en.pdf Looks like there's AQ, 2-pass VBR and support for interlaced encoding.

I have to almost double the bitrate with badaboom or mediacoder to achieve comparable results to x264. I really really hope cuda encoders evolve into something great, but its not there yet. |
