The second half of 2011 has seen some high profile CPU releases in the form of both the AMD Bulldozer series and the new highend Intel SandyBridge Extremes. Both platforms offer us Hexcore solutions with additional benefit of inclusion of the AVX extensions which whilst enjoying modest support already (Sonar’s inclusion of the extensions has been widely reported), looks like it could be important as more and more firms adopt and optimize with their software to support this functionality.
December 2012 System Dawbench Results
So a brief overview of our findings.
The AMD Bulldozer Dawbench results surprised us and not in a good way. Performance for this new generation of CPU has been lackluster at best and in a surprising result performance wasn’t much improved over the previous Phenom X6 series CPU and even fell behind it in some testing. The shared cache in the AMD Bulldozer design we suspect could be involved here bottle necking the CPU but either way it does seem that this CPU’s design isn’t ideal for audio usage.
The Intel Sandybridge Extremes however continue to push forward performance wise in the DAWBench testing and we see some great performance gains in the initial testing. At stock the isn’t much in it with a overclocked 2600k and this might still be the better option for a lot of users but the X79 boards do permit you to make use of a lot of extra memory slots (the board allow upto 8 memory sticks) if you pick up the right model which allows those working with film and TV scores to have access to upto 64GB’s of memory, so ideal for people running programs like VSL or large EW sound banks.
The initial testing of an overclocked Sandybridge Extreme 3930k does show some astounding gains when over clocked with 30% – 40% across the board, this could make these CPU’s reasonable value for money. Unfortunately our initial testings has been done on the B2 release CPU’s which are running a bit hot when pushed to this level of performance. Intel has announced a refined CPU revision (the C2) late January 2012, so we expect to be offering an over clocked edition offering this performance gains around the start of February all being well. Of course we shall publish updated results from our testing as and when it is carried out.
