However I got a lot of BSODs when I put in the quad core CPU (see my other threads). The QX9650 replaced an E8400 in a P5K-E motherboard. WinXP works great but a lot of this multi core stuff is well sub-optimal on it, BUT you also need modern software to use an i7 properly. I had to run three different media players (VLC, Nero and WMP) on some 1080P 50mbit/sec videos, concurrently, with VLC doing sharpening on each frame, plus Handbrake doing some silly video re-rendering. In win7-64 I really struggle to approach 100% loading on the 6 cores. But this is really the OS, not the hardware. Pretty obviously the processor is doing little more than moving along the VLC progress bar and the data transfer is being done by DMA straight from RAM to the video card. Playing back a video with VLC loads 2) to 0-1% (yes between zero and 1%). Playing back a video with VLC loads 1) to 30% and 2) to 15%. Running any of my video rendering progs (Vegas, Handbrake, etc) shows the i7 to be 5% faster!Ī given rendering task (Handbrake doing a 1080P video) will load up all 4 cores on 1) to 100%, but on 2) it loads them to only 60% and runs at a similar speed. One is a, i7 quad core running at 3GHz and the other is a QX9650 running at 3GHz.Įverybody tells me the i7 should be vastly quicker. I would say the answer to the OP depends on the code that's running.įor example I have two computers here.
