[QUOTE=SubZero;2632454]Thank you for replies
I have intention of possible AMD 4 core or 8 core for using PowerDirector Ultra 64 to process movies. It has a YouTube upload feature built in and so would process videos and upload at the same time, using more threads.
There would be large file copy operations, audio recording, conversion and saving, etc.
It would seem AMD bulldozer is more like AMD Tonka Truck for gaming compare to Intel so I would not get new AMD for that. I have excellent Intel 980X extreme setup with 3GIG GTX 580 running my 30" LCD mostly at 2048x1536.
But new information and curiosity is about Windows 7 64 bit can actually use cores for above tasks as mentioned.
I could even host an MFC device to print, scan, etc from USB on that machine and get thread benefit, correct?
Windows 7 takes care of all cores present for such operations?
Thank you for helping[/QUOTE]
Uploading videos to youtube will possibly use 1% of your CPU time … of one core … if you round the figure up to the nearest percentage …
The thread-handling for the current AMD bulldozer chips is not correct in windows 7 … but apparently they will be in windows 8, giving a large boost in performance (apparently).
Current Intel ix-2 & soon to be released ix-3- series CPU’s have hardware H264 video encoding, but only when using the intel video GPU … might wait for the i3 series to launch … because i2 series requires you to be using the onboard intel GPU, or it’s processed (slowly) by the CPU.
File copying is extremely low CPU bandwidth. With Direct Memory Access (DMA) the cpu is literally disconnected from the memory bus for most of the transfer time, and is processing other things.
Transferring scanned images from USB is also very slow … but once it actually gets into memory, a fast multi-core processor will help process images - in terms of applying different image rendering techniques/masks/correction algorithmns … if it’s just scanning and saving, a dual core CPU is more than adequate.
According to here performance was more than adequate on a phenom 2 when mixing 3 HD video streams … a bit jerky when mixing 4 video streams, and almost unusable when mixing 5 HD video streams.
I’m not entirely sure why you need to upgrade your rig from a Intel 980X extreme for some basic video encoding … unless you intend to be gaming & processing/encoding Hidef Videos simultaneously.
I’d have suggested that you could also use your video card to encode video’s, but nvidia has been proven to have intolerably poor video output quality when using GPU encoding …
For what you need, it seems like you could get away with a small cheap i3-2xx PC and a $50 KVM switch.
