Another silly Mac vs PC debate that should have its own thread. I use Edius Pro and it doesn't run on Mac nor do I have any interest in a dual-boot environment. My PCs run great, have for years and I have no need to switch.

Dont fan the flame if you dont like the fire. Better to let it burn out.

To return to thread's subject:
Just received my SEK2500 upgrade kit for the Samsung F9000 TV. This enables 60p from PC + better dimming + better frame interpolation. I will test using it the known issues for the AX100 (fast moving scenes, rolling shutter, flickering with excessive sharpness) and come back with the conclusions.

That is primarily for historical reasons, since in the old days high powered computers operating in a windowed environment was pretty much exclusively a Mac domain, so anyone who did high end graphics work used one. Those days are long gone, but the brand loyalty in the field remained.

Cool. The fans on my PC operate at ~13db at idle, and not much more than that at load if I don't overclock the system.

What are the components CPU, graphic card, PSU . memory etc) ? Go post that on Tomshardware.com and see what they say about that.

The above graph illustrates the GeForce GTX 690's position in this variable envelope I'm describing. Stock, it achieves 71.5 FPS using a test system I'll detail on the following page in Unigine Valley 1.0 at the ExtremeHD preset. It generates an audible, but not bothersome 42.5 dB(A). If you're willing to live with a borderline-noisy 45.5 dB(A), you can easily overclock the card and get a stable 81.5 FPS using the same preset.

Most high end low noise fans in computers run at around 13db at idle. I prefer using Noctua fans, you can check out the specs for their products on their website (www.noctua.at). Apple is not exceptional in this regard (notice they don't tell you the noise specs under load, they only tell you what they are at idle). Of course fan run faster under load if you have set them up that way and will produce more noise, but even so you are talking about 19db, thereabouts. All of my case fans run at their minimum speeds. The only exceptions are those controlled by the motherboard using thermal profiles, but even under load I have never seen the board temperature go high enough to trigger a speed increase. Some of the fans even get switched off by the motherboard because the temperature is so low and they are not making an effective contribution. I have temperature probes monitored by another fan controller to keep track of what is going off the motherboard elsewhere inside the case. My RAID card also keeps track of drive temperatures in the two sets of drive arrays in the case, so I have a pretty good idea of what is going on temperature wise. My CPU (which is a mildly overclocked 3770K running at 4.3GHZ) has never exceeded temperatures of around the low 50s even when all 8 threads are running at maximum load. The cooling system in my case is way overkill.


The only fans which make sort of significant noise are the video card fans, and those only do that when under very heavy load. And that happens pretty rarely. If you are not overclocking you can get by even with fanless cooling solutions for both the CPU and the GPU with a well designed system. And in any case, since the GPU in my system is buried deep inside a case with 1cm thick sound deadening walls, noise it makes is attenuated.


If the MacPro has a single fan and never makes any noise, all that means is that the CPU/GPU are never being stressed (or they are throttling down under stress due to inadequate cooling), since they are the same CPU and GPU used in conventional PCs and will have exactly the same thermal envelopes and cooling requirements. There is nothing special or mystical about heat exchange where Apple knows some super secret formula that people who specialize in cooling (such as Noctua) don't know anything about.

Of course. And moreover, we are debating now some decibels instead of debating the most important things: performance per cost, OS robustness + ease of use... Let's put things again in order: when you buy a TV, you should expect maximum picture quality in all aspects, and only then you should think about the adjacent things like media player and so on. If when you buy a computer, the first thing is the noise, it means there is a problem... that computer should perform at best and not only in one application, but in general. And of course then the design, noise, power consumption. I don't say these don't matter, but not as the most important aspect.


Edit: very well mentioned Tugela, the throttling is an aspect most people don't know about... Many devices, especially mobile devices, do this silently and since you don't have a comparison, you don't notice. I don't want to say that the Mac necessarily does this, I just say there are a lot of things to be considered. Some of them technical. If it would be a magician, then this world would be full of Macs...

Core i7 3770K with Noctua only 13 DBA ? I don't think so.
