#Logic pro x 2020 software#Whilst there are a number of disk benchmark applications about, many simply measure the raw throughput of a disk’s performance whilst this can be a good approximation for real-world performance for video applications (which require a high data rate for relatively few files at any one time), audio applications require modest data rates - but typically for hundreds of files simultaneously: each audio track and each microphone position of every note being played in a software sampler will require access to a different file (or part thereof) at the same time. A disk with limited I/O performance will limit the number of simultaneous record and playback audio tracks, will increase the time required to bounce tracks, and will limit the number of voices which can be simultaneously played in software samplers. The performance of disks containing audio is not just important for audio track recording and playback, but also for off-line bounce performance and - probably most importantly - software sample streaming. We ensured the single track was in live mode, to ensure all its plug-ins were being processed on a single CPU core. In order to ensure we were measuring only the single-core CPU performance, we took a number of precautions:Īs with the multi-core CPU performance tests, we tested two effects plug-ins, as Apple were claiming very high performance improvements with the Amp Designer plug-in Testing the single-core CPU performance was undertaken with 3 separate tests: The CPU usage for such tracks is displayed as activity in the right-hand-most bar in Logic’s Performance Meter, and is the cause of most processing overloads: a single complex instrument and effects plug-in chain can overload a system more readily than hundreds of ‘non-live’ tracks. #Logic pro x 2020 pro#In order to run ‘live’ inputs - that is, any audio track which is in input-monitoring mode or any software instrument track which is primed to respond to incoming MIDI - Logic Pro X uses a small buffer size and processes the track and some master plug-ins on a single CPU core. We’ve also included the Geekbench score for each machine, to give some indication as to how the real-world DAW performance compares against the synthetic benchmarks. We tested two effects plug-ins, as Apple were claiming very high performance improvements with the Amp Designer plug-in, so we wanted to see if this was a special case. We tested audio tracks with multiple instances of each effect plug-in, so as to reduce the influence of the disk playback performance on the result We ensured that an empty track was selected during the playback tests, so no ‘real’ track was using the ‘live’ CPU core in addition to the ‘non-live’ cores In order to ensure we were measuring only the multi-core CPU performance, we took a number of precautions: Software Instrument Performance - Multiple Alchemy software instrument tracks Įffect Plug-in Performance #1 - Multiple Amp Designer audio tracks Įffect Plug-in Performance #2 - Multiple Space Designer audio tracks. Testing the multi-core CPU performance was undertaken with 3 separate tests: The CPU usage for such tracks is displayed as activity in the left-hand-most bars in Logic’s Performance Meter. This gives it some degree of flexibility in terms of allocating resources across multiple processors, and accommodating demands from background applications and processes without interrupting playback. In order to maintain optimum efficiency and provide the highest performance, Logic Pro X uses a large buffer size for any tracks which do not require a ‘live’ output. Other than this, the measured performance is roughly as predicted by the benchmarks. #Logic pro x 2020 mac#However, it is possible that there are improvements in the new Mac Pro which, when adopted by other developers, will yield similarly impressive performance gains However this performance gain is not realised with the other plug-ins under test - it would be unwise to expect to gain this much performance increase across the board. Unfortunately we’re not able to test exactly the machines Apple quote (Late 2013 Mac Pro 12-Core and Late 2019 Mac Pro 28-Core), but their claimed performance boost of 6.5x between the two machines running Amp Designer plug-ins is roughly borne out by the boost between the machines we have measured (both at comparable point in their respective ranges) Īmp Designer appears to be highly optimised for the new Mac Pro (or vice versa), resulting in the large performance gain in this combination. The new Mac Pro typically offers between 4-7x the performance of the previous generation Mac Pro
