quad-core macbook pro performance questions
I'm considering upgrading equipment from last year's dual-core i7 macbook pro to this year's quad-core model. normally i dont worry about increasing processor speeds as a reason to upgrade but i'm wondering if the new quad-core's might be worth it.
I am only concerned with tethered capture speed (Canon) and image adjustment preview window refresh. I do not care about processing speed. I especially feel that the image preview refresh needs to improve. I use a usb repeater that greatly improves tethered capture but i wish it was better still.
So does anyone have experience with these 2 generations of macbook pros? I have 8 GB ram and plan to install SSD in either the new computers or in the current ones i have.
Anyone from phase one with benchmarks for the new macbook pros compared with older ones for capture and on screen adjustments?

In tethering all different computer resources are in use: USB transfer (already optimized), CPU, disk and graphics adapter. Of all these resources, the disk is in general the slowest, hence upgrade to SSD will give the best improvement, is my assumption. Newer MacBooks have faster processor and graphics and will as a result add to the improved performance, but maybe not significantly during tethering. 0 -
What about having the image rendering faster on screen and being more responsive with image adjustments? Maybe its just me but it seems that 6.2.1 is a bit slower in that area than previous versions? So would a quad-core processor make any difference in the responsiveness of image adjustments? Or by adding more cores will only processing benefit? It is a bit maddening to wait for image previews and adjustments to come into focus on set with the whole crew waiting. 0 -
Image preview refresh is a CPU/GPU (with OpenCL support) activity. As I hinted to in my previous post, I surely expect improvements in this field, in particular with a SSD in the box. 0 -
anyone from phase one have any benchmarks or comparions between the quad-core and dual-core MBP's?
I'm sure the quad-cores will be faster but I'm trying to find some relevant info regarding C1P specifically before purchases are made.
I can go to barefeats or macworld for their benchmarks but they certainly dont test C1P.0 -
its very hard to quantify with a test if the quad MBP is faster at tethering than another system. One test i run is to shoot a 5d2 tethered with standard 4.5m cable from canon in a continuous burst. Timing how long it takes to preview the final image and the number of files able to shoot in the burst (this is mostly limited by usb transfer speed but also indicates the drives ability to write the files). I found that the 2.3 quad with 8gb ram and sata2 120gb ssd from OWC was about 30% slower than a 6core macPro if I shoot to the boot ssd volume on both the tower and laptop. I have been able to get this gap even closer with hardware tweaks (costs alot to gain another 10% but I really want to not need to cart my towers around).
Processing speed is quite amazing on the quad MBP even when stock. Processing speed is within 20% of the macpro and over 200% faster than my 2010 MBP!!!!!
