content: Neat stuff!I like how you can mouse over any of the cards and the display changes to percent. I'll have to remember that trick.I wonder if there's an easy way to test on board video too. I'd guess that onboard video would use less power just by the absence of the fan and extra circuitry, but I imagine it's hard to say.Thanks for the link, I was just thinking about picking up a newer graphics card.

content: Quote from: shafri on October 24, 2010, 12:43:46 pmThere'san article about these on tomshardware. It explains some of the basic differences, and near the end of the first page they have some power information that suggests that your 4650 uses less power overall in most of it's incarnations. It's probably not conclusive, but it might be a start.

content: Video cards are heavy duty minicomputers these days, its a reason CPUs can do more, the video processing is off loaded to a dedicated processor, with its own OS and memory. It can draw a lot of power, depending on what needs be done: tip, look at their heatsinks!

At present with 2x GTX295 (Quad SLi) and a 4.2GHz CPU overclock.. my system is pulling over 750W from the wallI'm just hoping that as technology moves on and dies get smaller, the power requirements for such parts will be reduced whilst still being able to perform spectacularly.

content: Quote from: orbiter on October 24, 2010, 09:00:39 pmDon't count on it. Future processors will probably be a little more efficient without much of an increase in computing power. CPU design is getting very close to hitting a technological wall meaning that in order to make significant increases in processing power, dies have to go 3D instead of the conventional 2D.

content: Quote from: TopherTheME on October 25, 2010, 12:42:19 amThere is a lot of room for improvement. The biggest part is to abandon x86 in favor of better designs. Depending on what you want, ARM, MIPS, and Cell are probably the best bets.http://www.silentpcreview.com/forums/viewtopic.php?t=49884&highlight=&sid=aa2474b860cb4f78b90725897a93e9b2Quotehttp://forums.reghardware.com/forum/1/2008/10/14/arm_vs_intel_umd_biz/QuoteI have even "designed" a PC based on the BeagleBoard.Of course, that image is a bit outdated now that there's PandaBoard.http://pandaboard.org/

content: Quote from: shafri on October 25, 2010, 01:52:08 amThe original BeagleBoard is a 600MHz Cortex A8. The new BeagleBoard xM upgrades that to a 1GHz Cortex A8, and the upcoming PandaBoard upgrades it even further to a 1GHz dual core Cortex A9. Not enough for serious development work but more than enough for many common PC uses like web browsing, document editing, and media playback. For something that needs more than one of those boards, a board based on a Cell would be great, but I'm not aware of any.And I think Linux is the best general purpose OS. Everything can be tweaked if you know how to. For network-heavy applications, FreeBSD can often be an even better choice.

content: Quote from: NiHaoMike on October 25, 2010, 01:31:04 amIf you want to trade power for performance. I wouldn't choose an x86 CPU for something like a cellphone either, they're clearly optimized for performance. But I wouldn't buy a PC with any current ARM or MIPS either, not enough bang (as in performance) per buck. I've nothing against alternative architectures, but they're clearly optimized for a different market. Optimizing something for power or performance is very different, you can't expect one CPU to be good at both. One of the reasons most architectures other than x86 now focus on niche applications is that they failed to compete on performance. Same with Via.Quote from: NiHaoMike on October 25, 2010, 01:31:04 amThe problem for competitors like ARM is that the cost of this x86-to-RISC translator is basically constant, so with the increasing number of gates in modern CPU's and decreasing cost and power per gate, the extra costs are becoming less significant. They've been doing this since the P6 (Pentium Pro) I believe. The number of transistors used in the whole Pentium Pro is small (5.5M according to Wikipedia) compared to a modern CPU (382M for Clarkdale according to Wikipedia), and the translation logic was only a small part of the Pentium Pro. The implementation might be more advanced in modern CPU's, but I can't imagine it being significant in terms of transistors or power.Quote from: NiHaoMike on October 25, 2010, 01:31:04 amLet's drop the RISC vs. CISC debate, it's not the 1990's anymore. Modern processors are somewhere in between.Quote from: NiHaoMike on October 25, 2010, 01:31:04 amThis is not true anymore since the Core i3/i5/i7/Pine Trail.

content: In the portable segment, ARM easily beats Atom. In the high performance segment, I don't think there's any x86 that can compete with Cell. X86 does well in the middle, but the gap is closing from both sides.I think there should not be a hardware decode stage (or make it bypassable) and let the compiler do the hard work. A software-based compiler will not be restricted by complexity limits.

content: Quote from: NiHaoMike on October 25, 2010, 03:35:17 pmLast time I checked, x86 CPU's (eg. Opteron) were doing pretty well in the HPC market. In thesupercomputer top 10 of June 2010, numbers 1, 2, 4, 6, 7, 10 are Intel/AMD powered. Number 3 is hybrid Opteron / Cell, and numbers 5, 8, 9 are something else (Blue Gene). Cell is hardly dominating there. I wouldn't call supercomputing a real threat for Intel/AMD, since it's a tiny niche market compared to PC's. I'm not aware of anything PC-like using the Cell, but maybe I missed it?One issue with complex CPU's like the Cell is that it's hard to get software developers to use them efficiently. The PS3 is a closed platform, but getting desktop software developers to optimize their software for the Cell is much less likely.Quote from: NiHaoMike on October 25, 2010, 03:35:17 pmIt's likely that the Atom netbooks will lose marketshare to ARM, but remember that the Atom is really slow compared to an entry-level Core i3/Phenom, probably about the performance of mainstream CPU's ten years ago or so (at least the low-end Atoms). ARM is still a long way of from competing with the AMD/Intel mainstream products. I don't see the Cell competing in the high-end-PC/workstation market, are there any workstation level applications yet? A major issue in the PC market is backwards compatibility, people still want to run the crappy VB6 app from many years ago. Getting them to switch will require a major advantage in some other important area for the user.Quote from: NiHaoMike on October 25, 2010, 03:35:17 pmThey tried that with the Itanium. Ask HP/Intel how that worked out. Turns out compilers didn't improve as fast as Intel had hoped, and didn't handle the complexity very well.

Even when choosing my 8ports 1GB switch hub, I got an smart model by ASUS , that it does power off the unused ports , or use an low speed mode at the ones that they stay inactive for long periods.The only power hungry device next to me its the SONY CRT , that belongs in the past decade..Go Green with GIGABYTE P45 Motherboards /???Launch your Dynamic Energy Saver today! /!

content: So roughly 15 Cortex A9 cores would fit onto the same silicon footprint as a single i7 core. (Forget the Atom, that's a really lousy CPU.) And I'm sure the 15 A9s would outperform the single i7. The A9s will definitely do much better for power, particularly at low load where all but one of the cores can be powered down.So if one ARM core couldn't outperform one x86, the fact that you could fit many more ARM cores in the same amount of silicon would mean ARM would deliver more performance per chip production cost, assuming the same process.

content: Quote from: NiHaoMike on October 28, 2010, 04:12:10 amYes, with a big but - either your problem needs to be highly parallelisable or you need to be highly skilled at multi-core programming to use all of the cores efficiently. In general-purpose computing there are currently diminishing returns from additional cores, partly because compiler technology hasn't caught up and partly because it's more difficult for programmers to think about concurrency, but in specialised or embedded situations it's easier to conceive of a situation where all of the resources can be used maximally.
