Nice review but the score at the end seemed a bit low. Why mark it down so much for speed when this card outperforms all other cards at it's price and greater? Surely speed is relative to the price point of the card?

But then what's the point of the value score. I'm not a big fan of this new system

FINALLY!

Thank god. Such a good card for the money!

tried to read this on my 2.2 desire but was impossible as the page kept refreshing - anyone?

Wahoo!

I've been trying to find a second 5850 at a reasonable price and this one fits the bill. Roll on payday for Crossfire goodness :D

Absolutely fine on my Galaxy S with the Bit-Tech Android app 1.3.

This USED to be the case, but we now rank all cards on the same speed scale. A GTX 590, for example, will be 39, a stock 580 34, and so on.

What!!!....get with it BT, why has it taken so long for you to review a product that other sites were testing weeks ago?.

I love this site and respect your reviews just about more than any other, but sometimes your not exactly, well,..current are you.

Why no overclocking?
Stickeh 10th June 2011, 10:59 Quote
Most sites are sold out of this...but overclockers JUST THIS MINUTE lowered their prices from £124.99 to £99.98! ( i saw the change going through google shopping, if you look still on google shopping its still at £124.99- as google updates prices overnight!)

Just placed my order! =D

I wish this wasn't true... sadly, it probably is. On the upside, it's heading towards a crash.

Nice find ;), it's just a shame that it's from Overclockers ::spit:: :|

I'd never even heared of Bitcoin-mining before...

Yeah this was my only bad feeling, but as they are holding stock...and the price so good. Can't grumble too much!

Me either, but my interests have perked.

Here's an Ars Technica article on Bitcoin which goes into mining.

In a process known as mining, individual Bitcoin users attempt to generate new coins by checking the integrity of the transactions list. They confirm the previous transactions and attempt to solve a difficult proof-of-work problem which involves exhaustively trying different solutions. There are a very large number of such potential solutions, so the likelihood of finding the solution depends how many other people are looking for it and how much computing power you devote to the problem. The first client to find the solution announces its good fortune to the whole network and earns a little reward for itself in the form of some shiny new Bitcoins.

By finding the newest solution to the proof-of-work problem, a Bitcoin client confirms the history of previous transactions and moved the transaction register forward, allowing new debits and credits to form part of the next block that can be mined to earn more coins. Future coins can't be mined in advance, because the computation to find the new block (and hence create new Bitcoins) relies on the the chain of previous blocks and the history of transactions since the most recent block.

My limited grasp of the issue means I don't understand that fully but hopefully it'll help someone.

thanks for the heads up on the android app - but I shouldn't need that to view a web page should I?

I am struggling to see what this has to do with a HD5850 from Sapphire?

Basically Bbq.of.DooM has hijacked the article. Apparently ATi/AMD cards are better suited to the concept of bit coin mining due to OpenCL.

Right that makes some sense but it is a still a rather random comment to see in a GPU thread.

I would hasten to guess that the majority of people buying this card have never heard of Bitcoin let alone plan on doing any "mining".
Kingsley813 10th June 2011, 14:05 Quote
Exactly, before I saw that comment I had never heard of it. I guess Google is your friend.
Comrade Penguin 10th June 2011, 14:13 Quote
Sorry for the hijack but a few people asked what it was so I thought it was worth pointing out.

As for the card it seems rather excellent value. Just about beats everything in the £100-150 bracket and sits at the bottom of it. If Bulldozer arrives soon rather than September I could see myself building a system round the two.

Is it worth considering 2 of these over the current £200 single GPU cards?

Ive never really considered multi GPU setups because of potential 'issues' but £200 for 2 of these seems like a lot of power for money.

Two of these will roughly perform like a HD5970. You can use the HD5970 in various reviews to see how these would compare to say a GTX570 or HD6970.

Normally I would say Crossfire for this money is worth it however the HD58xx were known to be a little flakey when it came to CF performance / stability so it may not be the best bet.

Thanks to improved CF scaling 2 x HD6850 (which are slower in single card configs) would be a better CF option.
