I just upgraded my Asus P8Z77-Mpro from an Intel I5 3570K to the Intel I7 3770K to allow me to encode video faster. Unfortunately, just the opposite occurred, and I am puzzled. I have the Asus set to Fast AutoTune mode, so it overclocks the CPU and GPU, but that made little difference. For example, encoding from h.264 file to MJPEG took 2:15 (min:sec) with the I5, but takes 2:44 with the I7. After installing the I7, the MB detected new CPU, and adjusted itself, and windows indicated it installed new device drivers. The windows CPU performace rating for the I7 calculated 7.8. Unfortunately, I do not recall what the I5 indicated. Is there a way to see the history? What may be causing this encoder performance downturn?
Often the probelm is not the program or the cpu but your harddrive system(s).
For example if you only have 1 drive then the program has to read and write to the same drive all while fighting for I/O with the OS. So you see in this case the maximum speed you can get is half of your harddrive speed.
Depending on what program you use its often recommended to have at least 2 drives and as manay as 4. source and destination drives at a minumum and Os, Source, scratch, and destination drives make up the 4 drive setup.
What program are you using (is it multithreaded and HT capable?)
Please list your system spec's. Make and model of all the components.
The system is the same, I only upgraded the CPU. So the HDD is the same as before. The encoder is from an SDK made by Leadtools, which I believe is multi-threaded. So that's why I am puzzled. The OS is Windows 7 pro, 32 bit, with the Asus MB using its on-board intel graphics 4000. I've been told by Leadtools, that the encoding is CPU grinding mostly. I am using for the main drive an SSD 64GB. But the video is on the HDD.
