1 2011-01-22 00:00:56 <luke-jr> if my new PC uses max 5 amps, will a 500 W power supply be able to handle adding a high-end Radeon or two? :P
 2 2011-01-22 00:01:33 <luke-jr> tcatm: git!
 3 2011-01-22 00:01:37 <tcatm> One HD 5970 should work
 4 2011-01-22 00:01:59 <luke-jr> 5970 requires PCIe 2.1, doesn't it? even my brand new mobo doesn't have that&
 5 2011-01-22 00:02:44 <luke-jr> 2 would push it over the limit?
 6 2011-01-22 00:02:55 <tcatm> luke-jr: git seems to be a good idea, but I have to re-structure my directories for that to work well
 7 2011-01-22 00:03:17 <tcatm> I have a 850W PSU here that can't handle 2x 5970
 8 2011-01-22 00:03:29 <luke-jr> if 850 can't handle two, how could 500 handle one? :/
 9 2011-01-22 00:03:47 <tcatm> I have another 850W PSU that can handle two just fine
10 2011-01-22 00:04:12 <tcatm> But a single 500W can never power two 5970.
11 2011-01-22 00:05:39 <luke-jr> wait, I meant 5/4 amps
12 2011-01-22 00:06:00 <tcatm> As in 1.25 amps?
13 2011-01-22 00:06:04 <luke-jr> yeah
14 2011-01-22 00:06:14 <luke-jr> I forgot I had the measurement thing around 4 loops
15 2011-01-22 00:06:29 <tcatm> That's about 150W
16 2011-01-22 00:06:34 <luke-jr> hmm
17 2011-01-22 00:06:39 <luke-jr> so Radeons use how much?
18 2011-01-22 00:06:47 <tcatm> (I assume 115V AC, )
19 2011-01-22 00:07:03 <luke-jr> 120 I think
20 2011-01-22 00:07:09 <tcatm> Close enough.
21 2011-01-22 00:07:53 <tcatm> IIRC one HD5870 consumes about 200W mining Bitcoins
22 2011-01-22 00:07:56 <luke-jr> so about 300-350 per Radeon? :|
23 2011-01-22 00:08:01 <luke-jr> ah
24 2011-01-22 00:08:25 <tcatm> A 5970 should be ~300W because of reduced speed and core voltage
25 2011-01-22 00:09:00 <luke-jr> why do video cards use more power than the entire system otherwise? -.-
26 2011-01-22 00:09:03 <tcatm> so 450W incl. your system, probably close to 500W at the plug.
27 2011-01-22 00:09:11 <luke-jr> especially considering I already have a pretty awesome IGP
28 2011-01-22 00:09:22 <tcatm> Because they're like 60x as fast as your quadcore CPU? :)
29 2011-01-22 00:11:18 <ineedmoney> oh nice
30 2011-01-22 00:11:27 <ineedmoney> noagendamarket: hey!
31 2011-01-22 00:11:33 <noagendamarket> hey
32 2011-01-22 00:25:20 <ineedmoney> how's it going, bro?
33 2011-01-22 01:15:32 <midnightmagic_> any chance someone could check libertyreserve.com and tell me if it's down for them too? :-)
34 2011-01-22 01:21:57 <[Noodles]> seems online to me
35 2011-01-22 01:26:52 <necrodearia> midnightmagic http://downforeveryoneorjustme.com/
36 2011-01-22 01:38:19 <MT`AwAy> here, another site accepting bitcoin!
37 2011-01-22 01:38:55 <andrew12> orly?
38 2011-01-22 01:40:21 <MT`AwAy> yep
39 2011-01-22 01:40:29 <MT`AwAy> http://www.autovps.net/?Currency=BTC :p
40 2011-01-22 01:44:34 <andrew12> if gpus are so fast then why don't the graphics companies make cpus?
41 2011-01-22 01:44:54 <tcatm> They wouldn't run windows.
42 2011-01-22 01:45:13 <andrew12> why not?
43 2011-01-22 01:45:37 <tcatm> Windows only runs on x86
44 2011-01-22 01:45:43 <andrew12> that's true
45 2011-01-22 01:46:07 <jwalck> GPS would be terribly slow at general purpose things too:)
46 2011-01-22 01:46:22 <andrew12> jwalck: really? why?
47 2011-01-22 01:46:52 <jwalck> andrew12: the cores have a limited instruction set / basically vector processors
48 2011-01-22 01:47:05 <ArtForz> yep
49 2011-01-22 01:47:06 <jwalck> and in current installations low bandwidth to the rest of the system / too little memory
50 2011-01-22 01:47:21 <andrew12> heh
51 2011-01-22 01:47:24 <andrew12> memory wall!
52 2011-01-22 01:47:25 <ArtForz> main problem is they're really wide vector processors
53 2011-01-22 01:47:25 <jwalck> AMD is working on merging the two more though, check out AMD Fusion and APUs
54 2011-01-22 01:47:45 <ArtForz> ATIs are 64-SIMD
55 2011-01-22 01:47:53 <andrew12> jwalck: also technically CPUs have a limited instruction set too.
56 2011-01-22 01:48:10 <ArtForz> well, actually 64-SIMD of 5-VLIW or 4-VLIW units
57 2011-01-22 01:48:20 <ArtForz> nvidias are 16-SIMD
58 2011-01-22 01:48:51 <ArtForz> and each "core" is a simple pipelined in-order design
59 2011-01-22 01:48:56 <jwalck> andrew12: not limited in the same sense. its ment for everything
60 2011-01-22 01:49:09 <jwalck> and optimized for whats common
61 2011-01-22 01:49:22 <ArtForz> also GPU memory subsystems aren't designed for random access
62 2011-01-22 01:49:24 <andrew12> well are they turing complete? :p
63 2011-01-22 01:49:27 <ArtForz> and they don't have much cache
64 2011-01-22 01:49:28 <ArtForz> yes
65 2011-01-22 01:49:36 <andrew12> then you can do "anything"
66 2011-01-22 01:49:40 <ArtForz> you could implement most of a OS on a modern GPU
67 2011-01-22 01:49:44 <ArtForz> it'd be pretty slow though
68 2011-01-22 01:50:09 <jwalck> not ment to and cant is different:)
69 2011-01-22 01:50:17 <andrew12> instead, use your gpu for complicated things, like generating bitcoins! :P
70 2011-01-22 01:50:26 <andrew12> they're probably so fast BECAUSE they have a limited instruction set
71 2011-01-22 01:50:41 <ArtForz> the instruction set really isn't THAT limited
