Yosemite benchmarks thread

Don't confuse tests that are designed to test the hardware (Geekbench) with those that are designed to test the performance of the OS (XBench).
XBench is the only test that can teach us on OS optimisation in respect to quartz and the UI (forget it for openGL, it just spawns some spinning squares).
Clearly, the quartz code, which powers all the 2D UI, is much slower now.

Ugh, I see what you mean. Not as bad but not good. BTW, I tried same on 10.10.1, different machine but almost identical results.

cinebench, geekbench… this system is faulty on every graphic aspects.
it's since lion that federighi is dropping frames, but i never seen low performance like this between one release. yes ok changed the UI (not so much if you turn off aero) but still.

To mitigate what I said, the Quartz code itself may not be slower in Yosemite, and it could be that XBench triggers updates in other processes (the Window server for instance) in Yosemite and not in Mavericks, due to changes in the graphics pipeline. That may cause some overhead. Looking at activity Monitor during the benchmark could be informative.
It's also quite possible that point updates will improve the situation.

One performance issue I have noticed, I get screen saver lock out. I suspected a 3rd party screen saver, switched to something very light, Message. If Netflix is playing, you have stand on the keys to get an interrupt. I haven't seen anything like that on any Mac is a long time.
