In basic terms, Intel Quick Sync can only be used if the encoding/editing software that you use actually has support for using Quick Sync (which VRD does) and it can only be used with a supported Intel CPU that has a built in HDxxxx, Iris Pro or GT2/GT3e/GT4e graphics chip, it cannot be used on any other type of CPU and nor can it be used with any other graphics chip, including any dedicated cards that you add to the computer.Ĭurrently Quick Sync is restricted to i3 and i5 Dual core, and i5 and i7 Quad core CPU's that have the built in HDxxxx, Iris Pro or GT2/GT3e/GT4e graphics chip, and belong to a select group of Socket families, and all 6 and/or 8 core CPU's that belong to different socket families do not have the HDxxxx, Iris Pro or GT2/GT3e/GT4e graphics chip, so they cannot support the use of Quick Sync, however they are very efficient and usually faster than 4 core CPU's when doing what we call "Software based Encoding" as long as the software that you use supports that number of cores.Īlso, when you buy a specific CPU that has the built in HDxxxx, Iris Pro or GT2/GT3e/GT4e graphis chip, you must also buy the appropriate motherboard that supports that particular series of CPU. This Post could also be used in its own right as a thread and placed as a Sticky somewhere, because i think it may be of help to other members who may not know much about this topic.įor Encoding purposes, and for the purpose of this particular post, the information i provide will just refer to the Intel i3, i5 and i7 series of CPU's because those are the most widely used for Quick Sync encoding, however because the i3 and some i5 CPU's are only a dual core CPU, it is highly recommended to use an i5 or i7 Quad core CPU for best encoding times, especially if you still wish to use Software based encoding like i do, because the encoding utilizes the actual CPU with the software to carry out the work load, where Quick Sync utilizes the built in Graphics chip on the CPU to carry out the work.
I7 QUICKSYNC UPDATE
Hi everyone, i notice quite a lot these days (not just in this forum) that there seems to be fair bit of confusion about Quick Sync, and who can and cannot use it, so i will try and explain how it all works in this post as good as i can, but i did write this some time ago, and i have not updated the information relating to any new CPU or socket family beyond Skylake, so if anyone has any more to add, or spots an error in what i have included in this post, please let us know and i will update the information. Their best processor can barely compete with Intel's low end and Intel's high end will blow you away. AMD has really slipped in raw CPU performance over the last few years. Honestly switching from any AMD processor to Intel is going to be a big improvement. Although you'll still see a marked reduction in CPU usage which will help them run faster then they would doing a CPU encode. The resizer and deinterlacer are single threaded so performing either of those will slow encoding. HD is a little slower but you'll still see a big improvement over a typical CPU encode. I don't know how much improvement you'll see but on my system, which has an older Sandy Bridge i7 2700k I just encoded an entire 30 minute program (SD) in 3 minutes. However a faster CPU will improve encode times for the frames that do need to be encoded.
I7 QUICKSYNC PC
Smart editing is mostly disk bound, so getting a PC with two drives and using one for input and the other for output will provide the most notable improvement. QuickSync is not used for smart editing, so that will not improve anything, but upgrading to a faster PC might. at the lower end with "bang for the buck"!Īt the higher end, needing performance. The next generation Skylake is due to come out THIS year (quad core).Maybe by August we hope.ĪMD is good. (CPU and software is still the best quality) Only get the latest generation of Intel CPUs.
Quality of video encoding then the last one. Each generation (Sandy bridge,Ivy bridge,Haswell chips) of QuickSync produces a higher With QuickSync, YES, several times faster. A quad core that has 4Cores/4HTs may not have this problem.ģ.Is the biggest improvement when I would need to recode something from MPEG 2 -> H.264?. My 6 core is faster in VRD without HTs because VRD is limited to 8 "cores" and I have 12 to choose from.
intel is the best at high end performace.
I7 QUICKSYNC UPGRADE
My 6 cores/6 HyperThreads not used much.Ģ.How much improvement will I see if I were to upgrade to the I5 line of processors (50% reduction in time?) - what about a leap to an I7?.ĭepends on exactly what you are coming from. Smart Editing makes me think "Fast Frame Copy". Click to expand.1.Will my smart editing time remain about the same?.
