Intels GPU is nice if they would pack some more cores or make a discrete card (wee need more then ivybridge) it would be interesting
the Intel Encoder still utilizes the EUs @ least on SB not sure how it will be for IB but i think not much will change here and the speedups come from other things (more EUs,Clocks) for the Motion Estimation so you have a slowing down effect their. Im trying currently to get this as a Quicksync Result http://blip.tv/file/get/Cr4bl3r-inte...64tuned349.mp4 this is the x264 result not bad for a Intel IGP (GT1 @ stock) the record overhead is very minimal so only 1 or 2 fps get lost overall

That's a Nvidia thing since introduction of the Tesla Series they keep it that way, also it could be that the Performance isn't lower but a restriction either in the Firmware or on the Driver level makes it artificially slower (it is really common these days to build blocks either into the Firmware or inside the Software above (Driver), much easier to handle and create different Product lines, without needing to produce different Hardware)
In earlier days you could lift these restrictions easily but be sure Nvidia learned from these System mistakes and Identification stuff becomes better, these applies to the whole usage of such artificial restrictions they also evolve with every brake, for the easy shader activation brakes (just replace the Bios with a different one) they decided to go back to the Hardware part and fix it with laser cutting the unused (or damaged) Shader impossible in the end (though it's easier todo even for multiple lines of Hardware just drive the chip to another line and cut it to what you want to be the end result) to circumvent in anyway Another good example would be Intels advancements here restricting overclocking and introducing the upgrade ability of CPUs with features with just a Code (still more a research thing then wildly used, good or bad you decide it in the end it has many cons) Though i find it funny that people yet doesn't understood that overclocking is dead and it's part of every product now and that especially the younger generation really let themselves be fooled with this, it's not anymore what it used to be in my days Since Software introduced the Multiple modular version system (develop the application with full features in the first place and then just leave features away and decide how to call the product that's now restricted differently, compared to the all feature version and set a different Price for it) Hardware manufactures saw the same possibility how to make use of that for their Purposes Btw these system even found it's way to Games in the End (DLCs) not every DLC though is developed this way but allot are, though instead of paying a lower price you pay a upgrade price Mass Effect 3 really showed how you use this System efficiently for maximum profits As Bill Gates Envisioned it everything becomes Software driven and use the same principles, though it's easy to Envision such things if you just walk into the Microsoft Research part and see how people their create such things "I have to tell you something i saw the future" is easy then and always was for him on Stage

http://www.brightsideofnews.com/news....aspx?pageid=4 My GTX 680 just arrived... fun stuff. Tweaking overclocks now. Just need to find a way to test NVENC and then I'll compare it to x264. EDIT: Was just supplied with an NVENC-enabled build of MediaEspresso, I'll do a 'formal' test if I can get time. EDIT 2: Not sure this is worth doing, at least at this stage -- MediaEspresso is restricted to Baseline@4.0, 25fps (with 50fps source), and CBR. No way of seeing if these are limitations of the software, or of NVENC. parkjoy is encoded in about 5 seconds (from a 50Mbps H.264 encode of the original so ME could read it), so twice realtime for that, which x264 can easily match.

That's nice. But it's got nothing to do with GPU decoding support.

x264 does have GPU decoding support.
It's called AviSynth input, where you can use whatever decoder tickles your fancy Would be nice, but not high priority because of the above working solution, I assume. |

indeed for decoding we have nvidia cards and quicksync from intel.

Hello all,
I use vegas pro 11 and would like some GPU acceleration, I have to choose the 580GTX or the 670GTX for nearly the same price (+ 5% for the 670). If Vegas pro will implement the new API NVENC, I think that could be a big advantage over the 580gtx on encoding process. But on workflow editing and preview, anyone could tell me if the 670 is better than the 580 ? Thanks (a trial version of vegas pro 11 is available at sony website). |

There is written in Release Notes of AMD APP SDK 2.7:
Additional features supported in SDK 2.7 and the Catalyst 12.4 drivers include: • Video encode using VCE Encode (Win7) • Open Encode update (12.4) Looks like it is supported, It may be new MFT AMD Encoder? Wonder what is Open Encode, similar to OpenCLDecode? |

new article with nvenc testing:
http://www.hardware.fr/focus/imprimer/67/ funny thing - at first they published article with results from MediaEspresso in CUDA mode, now it is updated with nvenc mode results |
