The difference is that one is a texture compression algorithm and the other is a rendering model covering shading as introduced with the latest publicly available DirectX.Ben_CustomPC said:We're also going to be covering things like 3dc and Shader Model 3 and what the differences are.

That's what I was thinking; just what kind of editor runs a magazine that leaves such in-depth articles to the last minute? It's not as if the work is going to cover breaking news. I get to write for the Institute of Physics now and then - I'm given a minimum of 6 weeks notice each time.DaveBaumann said:Ben_CustomPC said:If you reckon you could do the job (the deadline is in two weeks time and isn't flexible)
Well not quite - I have the article at home so am not looking at it right now. Note I am not trying to be critical of your magazine - I actually think it's the best new entry to the UK computer mag scene in a long long time.digitalwanderer said:Good comeback. 8)lizard said:If you mean was Custom PC the first publication in the UK to scientifically labs test PSUs (rather than looking at the box and guessing) then yes
As to the article on PSUs it seems you misread it. It clearly states that we tested the PFC effeciency - not the overall effeciency of the PSU.

As I sometimes say in my day job when well meaning executives toss out conflicting "goods". . .There's a certain tension there.
But I'll ask the obvious (tho not for myself), since magazines aren't web and usually an editor has a slot size in mind to fill. . .how "large" did you have in mind?

I'm not sure I'd want to write for a mag that doesn't know the basic difference between the two.

But from memory, in the summary table at the end of the article, there was a column giving % numbers that referred to PF. No mention in the data was given at all to the actual conversion efficiency of the PSUs, which as a reasonably knowledgable consumer are what's important to me - several orders of magnitude more so than how good their PFC is. How much extra heat the PSU is adding to my computer is of great concern. And I would expect numbers ranging from the 60% or so of generic PSUs up to high-70s for decent ones. The only person who I have found who does this in what I would call a scientific manner (as opposed to your definintion) in reviews of PSUs is Mike Chin at http://www.silentpcreview.com/
So perhaps whilst not factually wrong the article was (in my opinion)misleading in giving the impression that PFC is more important than conversion efficiency in a PSU.

Just a thought as it seems to me (I'm just guessing) that it is a lot of work in a short period.
'fraid I can't help anyway; have trouble writing three paragraphs.
Yes that would certainly be a possibilty if three people are up for doing it.
Nah, I'm not qualified on this one. I'm looking forward to reading the completed article and learning from it, I'm not knowledgeable enough to write it unless I cheat and pick Hanners & John's brains for the whole thing by PM.MasterBaiter said:Uh-oh... Digi's sniffing out his competition...
Thanks for your reply - I actually am referring to how much the compontents are using (in W) compared to how much is drawn from the mains (in W, not VA) when I talk about efficiency. This is important and not necessarily linked to how stable rails are etc. The reasons it is important are (a) the "wasted" energy costs you money (PF is only important if you are on a corporate supply contract with your mains supplier!) and (b) this same wasted energy ends up as heat generated in the PSU - which the fan therefore has to work harder to expel, hence needing to be faster and louder. As you might have guessed, I am very interested in keeping my machines as quiet as possible whilst still getting decent performance - and the first thing to do for peace and quiet is remove unnecessary sources of heat, before you start removing sources of noise To test for my sort of efficiency you could have applied a known load (even a lighbulb would do at a stretch - doesn't have to be computer related!) on the output side and then measured draw on the input side with a kill-a-watt meter or whatever; ideally though you are right you need decent equipment to draw known variable loads from the different rails that does approximate typical use ... not so straightforward!lizard said:The main reason we didn't test total effeciency was that this wasn't possible on the PSU test machines we had access too. Secondly, to some extent this is covered by the voltage stability tests which form the core of the article. e.g. when fully loaded (or close to, we did 5 different levels of load) the voltage is stable then it obviously is pretty effecient. Unless you are talking about how much it actually drains from the mains?
True, but it also showed us a great deal about what the people at the magazine looking for an article are like and I must say I like their attitude.Gnep said:Anyway, this has drawn the thread completely off-topic - for that I apologise!
