HD3850 does not support GPU mining..
True, but it does have a GPU, and it does depreciate, so it's valid to put it on the graph
Name me a card released 1500 days ago that does support GPU mining...

HD3850 does not support GPU mining..
Maybe not, but it is a good reference point on the graph. It supports double precision and up until recently would have been usable at Milkyway@home. I haven't owned any HD38xx cards, but had a 2600 for a while (until it died).
The 5970 points would be very interesting, and even the 4890x2's
OP: thanks for the graph

It's an interesting topic to research. I suppose there could also be a correlation between the drop in value and the release of a new generation of cards. Do you have any dates?
*EDIT*
Ok, I didn't saw your excel chart. The data is limited but hey, it's still a good start.

Thanks! - I've been lurking for a few weeks, but glad to post something people might find useful. I'm really only mining to support the network, and because I believe bitcoin is a fundamentally good thing; UK electricity prices really only allow a very slim profit margin for miners (we're talking 10% here).
I know I didn't collect a whole lot of data, but I don't have the time to do something more all-encompassing (I'm supposed to be working right now actually
). I think most people already know that products in the sort of bracket that GPUs inhabit (novel technology) follow an exponential curve with their depreciation - I just wanted to get a rough idea of the time constant.

Im suprised the 5770 is doing so well
Well, you don't get much MHash out of a 5770, but I've found it's a pretty awesome combination of MH/J and MH/£ - I picked up 2 for £50 each, and I'm running them at 1V@860,300 for a power draw of 78W and rate of 197MH/s. That's 2.53 MH/J and 4 MH/£.
Why is the 5850 on there twice? I'm curious to see where the 5970 would place.
Yep - there are actually 2-3 points for each card. There's the launch price, which appears at [0,100%] for all cards, then I generally found a mid-point price from a forum or archived news story, then a 3rd data point generally came from eBay, as beyond a certain date, it's harder to get hold of new stock. (and even when you can they're at unrealistically high prices)

The 5770 is there twice too. It's comparing the value of ~200 days after release and ~800 days after release. At least that's what I think.
Nice. Add in 5870 and 5970 I would imagine they will be outliers (I wish they weren't 
).
).

Interesting...
I'd be curious to see the 5870 on there as well, since it's one of the more highly sought-after cards out there.

[EDIT: Should mention this work was done in £££ not $$$ (or BTC )]
I've started doing a bit of small-time mining recently (~1.5GH/s) and I wanted to do some estimation of real profits, taking into account the capital cost of the mining hardware. After a bit of trawling, was amazed that I couldn't find a simple graph of GPU depreciation, so I made one. I'm not claiming this is comprehensive - I only looked at prices for mid-range ATI GPUs, because I thought the very high-end cards might follow a different price curve, and the very low-end cards are just hard to find prices for.
I basically looked for a few different cost points in the life cycle for the ATI 3000-6000 series - e.g. (i) the launch price, (ii) a subsequent price drop announcement, and then (iii) a used-price on eBay. The 'cost half-life' is about 550 days, or 18 months.
