Duo Core to I7 Sandy Bridge

[Liquid Ghost]

Anyone know how much more power in processing i will get going from a 2.5 Duo Core with 4 threads to a comparable I7 Sandy Bridge with 8 threads windows 7 and equal ram?
10% 20% 50%?

Hard to quantify, but I would expect a huge boost. To compare, my old AMD dual core 3GHz would do 104 on the Dverb test. My i7 quad 2.66GHz went to 320(Windows XP 32 bit) and 500(Win 7 64 bit). Since you never mention how much RAM you have, 8 would be minimum for a dual channel motherboard. I run 12GB on my triple channel systems and the new quad channel(x79 motherboards) should use 16GB(more is better, but always maintain the proper number of sticks and all should be matching. IOW, exact same brand and model). With the newer systems, matching RAM seems to be more important

That's the info i needed.I also should of said yeah 8 gigs of ram now but the new machine will have at least 16 if not 32.Did you see much improvement going from 8 gigs to 12 or 16?
Also your D-verb tests were they done at 44 , 48 or 88.2 or 96K.Aslo did you do you have results at 88.2 or 96?

The test is done at 48K, 24 bit at the 1024 buffer(see the sticky thread "i7 builds" in the LE on Windows section of the DUC). Its simply a bench-marking test so you can see if your build stacks up correctly against others, and running the test once or twice a year can let you know if your performance is suffering, so you can diagnose for problems. I was running 6GB of triple channel RAM. I doubled up so I would have plenty to allocate to RAM caching in HD(I set to allocate 6GB of RAM so all audio for a session is loaded into RAM). That's a benefit of HD software or the CPTK

I'm aware of the test at 48 but wanted to know if you did the same test at 88.2 or 96 that's all.The results should be half but you never know.

Never bothered with the higher sample rates as I don't work at them. I have worked on 96K sessions from another studio and the bog down my rig enough that I now convert to 48K(which is plenty good for my clients). Interestingly, the original sessions(the 96K ones), while done at 96K, are recorded poorly. 96K doesn't make for better recordings. A good engineer makes for better recordings.....

That's right so when i combine my enginnering skills & experience at 24 bit 88.2 the difference in tracking sounds and processing sounds make a difference to me.A good mix at any sample rate will sound good!

Dverb benchmarks are a performance measure followed by a set formula. Any variation off the accepted formula nulls the benchmark. The measure is the experience you seek.

i would venture it should be a nice boost in performance, as always there are bottle-necks to watch out for... an SSD system drive will give you some def. advantages and leveling the playing field, as will proper high quality RAM and a good solid tracking hard-drive... most boards now adays have very few bottlenecks within the system bus so as long as its from a reputable company you shouldnt have too many issues there..

but yeah at the end of the day, i have done mixes on a mac 10 years ago that sound just as good as those done with "faster" systems...

all seem to be on the right track though, 24bit, 48Khz is where its at... for most its plenty...

as posted above, 16GB RAM {1600Mhz} seems to be the magic number for the latest LGA2011 X79 chipset... make sure they are a matched kit.!, all tested for proper
low cas latency numbers... as i have recommended before.. kinston hyper-x genesis is a wicked place to start... i will be upgrading to 32GB RAM as soon as I get my i7 3930k HEX!

The dual core i7's are only found in laptops. They can be identified by the "M" at the end of the chip name. Actually the core i7 2600 desktop processor is a quad core with hyperthreading & turboboost. It is part of the Sandy bridge chip-set range. And you can expect huge boost.
