38 I think the formula "performance/money" is fitted better by AMD
39 than by Intel.
40 If you take "performance" and "forget the money" Intel will be your
41 friend.
43 I myself choose an AMD Phenom X6 1090T (which can easily by pushed
44 to be a 1100T by the way) on a ASUS Crosshair IV Formula. But a few
45 days agao I heard Gigabyte would be more AMD friendly...
47 I uses this mainly for rendering -- all cores can be used by Blender
48 in parallel.
50 Only my two cent ... you currency may vary.
52 I DONT WANT to start a flamewar here!
53 Its only my opinion I wanted to express :)
55 Best regards,
56 mcc
58 PS: If the siftware you will use is not capable to put full load
59 on the machine you will pay for more hardware than it is used.
61 PPS: Hyperthreading uses unused parts of a core to run stuff which
62 does not need the used parts of the same core. When you have 8
63 identical jobs running, there have to be 8 identical parts in the
64 cores available otherwise there is nothing to hypethread. It depends
65 heavily on the kind and mixture of jobs running on the machine whether
66 hyperthreading is a win or a marketing joke...
67 I myself (own opinion) feel better to have six physical cores capable of
68 running six identical threads doing six things real parallel, than to
69 guess, whether 4 of the eight threads Blender is showing me is
70 /possibly/ waiting for getting access to an unused part of one of the
71 four cores.
72 Yes, I am an AMD friend since Intel way of "handling" the P90 floating
73 point bug for their customers.
74 And since this 15 (?) years this decision was ok -- at least for me.
76 ;)
