Whether there is any benefit to 12 cores vs 8 or 6 depends exactly on what software is being used, and what tasks are being performed.
#MAC PRO 5.1 12 CORE 3.46 VERSUS CURRENT MAC PROCESSORS UPGRADE#
If the price is the same or lower, then that’s a win of course.Įxcept for very specialized tasks, anyone with an 8-core system should not be rushing out to upgrade to a 12-core system. Are 12 cores faster or slower than six or eight?Īpple’s own performance graphs show that at 2.93GHz, 12 cores are only ~30% faster than 8 cores in some cases, not the nominal 50% faster. See the next page for performance estimates for various scenarios. Skip it unless you know exactly why you want it. The 8-core 2.4GHz model is a dud for 99% of users. The 2.8GHz and 3.2GHz have a slower system bus by 25%.See the test results- this matters.Īll the single processor models consume 130 watts under peak load (far less when idle).ĭual-processor models have eight memory slots, for up to 64GB of memory using 8GB modules.įorget about 12 cores unless you actually have tasks(s) that benefit. The 6-core 3.33GHz model is the “sweet spot” - for many tasks it should prove to be the fastest of all the models by virtue of CPU clock speed. Single-processor models have four memory slots, for up to 32GB of memory using 8GB modules. Still, most RAW processing software is far from efficient, processing one RAW file at a time while leaving CPU cores idle.īottom line: 4 or 6 cores might perform just as well for many users as 12 cores. And even well written software has some coordination overhead, so a 45% gain would be outstanding. Or the task itself cannot be split among cores (you cannot bake a cake 4X as fast with 4 ovens).

Most software is not written well enough to take full advantage of the extra CPU cores. In the real world, life is not so breezy. In our dreams, 6 cores would yield 50% higher performance than 4 cores. It also has 50% more on-chip cache memory (same amount per core). The 2010 hexacore 3.33GHz model has 2 more CPU cores than the 2009 3.33GH 4-core model. Performance rarely scales perfectly with CPU cores Never before have so many choices been made available for the Mac Pro. This is the most complex product offering yet offered from Apple. I have disabled all extensions and Chrome hardware acceleration and the problem persists.- Send Feedback Related: CPU cores, Mac Pro, Macs, memory I was using Chrome beta (stable version + 1 basically) but have reverted to Chrome v.135 stable and am experiencing the same problems. I found what may be a related bug in the Chromium bug tracker, but I am not seeing the extensive corruption/glitches shown in the screenshot attached to the bug (maybe I'm lucky?!?), nor am I seeing any issues in webpages themselves, only the tab bar, address bar and bookmark bar. Clicking on a couple tabs usually makes it disappear, as does, again, switching applications. Another manifestation places a gray rectangle over the middle of the tab bar. Switching to any other application when that happens causes the black box to disappear instantly. It only appears to happen in Chrome, although oddly, one of the glitches that happens (not caught in the video, sadly) is a black rectangle appearing over the middle of the menu bar, outside of Chrome's window - but only when Chrome is in the foreground. 3, so I don't think that's related either. I did notice this issue before upgrading OS X from 10.10.2 to. The system upgrades mentioned above happened in February, and I have only noticed this issue within the last month-ish, so I don't think they are related. (Link is to a screen recording made with QuickTime Player.) I am having graphical glitches - a couple of different ones, but this is the one that's bugging me the most right now.

The graphics card uses the AMD drivers that ship with OS X.

#MAC PRO 5.1 12 CORE 3.46 VERSUS CURRENT MAC PROCESSORS UPDATE#
I have a 2009 Mac Pro (4,1) that has had the "unofficial" 5,1 firmware update applied (to enable additional CPU support), CPUs upgraded to dual 3.46 GHz 6-core Xeons and GPU replaced with an AMD Radeon R9 280x flashed for Mac.
