Chris is giving us his first comments:
I have received my Quad today!With 60°C, this dualcore processor is much cooler than the one of a PMG5 dual 2.5GHz which can reach 90°C.
This is the standard model with the Airport option.
When opening the computer, the first thing I have noticed if the rather short connectics for the second internal HD, as shown on this photo :
Indeed, the second connector for the Bay B is shifted when compared with the cable. I hope that with time it will not become an issue.
Another remark when using this Quad : it is rather noisy for a Mac; but when it does not really increase when launching heavy CPU processes, such as RC5-72; I hope it is not due to a problem with internal thermal probe calibration. With the application "hardware monitor" I could control that the CPU temperature was maintained around 60°C.
Another reader, Hubert, has sent us a Cinebench test performed with his PMG5 Quad 2.5GHz featuring 2.5GB of RAM, the rest being according to the standard model.
One can notice that the multi CPU speedup ratio is 3.16 for 4 processors. With a Dual processor model, this ratio was around 1.86. In other words, if the Quad is indeed a beast, it also loose more "crunching" power, almost equivalent to the performance of a single core.
