Yep ATI made huge improvements in idle power consumption. 18 watts idle for HD5770 and 27 watts for HD5870/50 is a significant difference compared to what HD4870/90 used at idle.

Check out how this can add up over time---->http://www.tomshardware.co.uk/...er,review-31495-4.html
I agree.. ATI has made a big leap in terms of performance and power consumption because the 5 series made it happen and its a good thing to have if you spend most of your time only just surfing the net and 2-3 hours on gaming...

Going by this graph it looks like HD5770 is using 60 less watts at idle (compared to HD4870) and 30 less watts at idle compared to HD4850 512 MB.

That can really add up.

the card performs just like most people expected which is more or less with the 4870. 56tmu and 24rop seem illogical for 800sp and 128bit bus. seems like it should be 40tmu and 16rop.


"Perhaps we were expecting too much, but the Radeon HD 5770 was a little underwhelming in our books. Where performance is concerned, we expected it to be positioned in between the Radeon HD 4890 and HD 4870, but our tests have shown that it was mostly a smidge lower than the HD 4870 1GB editions; which puts it closer to the 512MB edition of the Radeon HD 4870."


"The results seem to indicate the shortcoming of the 128-bit memory bus that the 'mainstream' Radeon HD 5770 possesses."

This is another reason I think HD5750 will be a better deal.

they really need to get a 5830 part out to fill that $100 price and performance gap. its hard to recommend the 5770 if you already have a decent card.

Yep...Hopefully they have been saving "harvested" cores for that purpose.

At this time the only reason to buy HD5770/HD5750 over HD4870/HD4850 is power consumption and maybe noise. (although the power consumption difference at 2D desktop is rather large. Definitely something to consider for those people who leave their computer on overnight)

there could be no 5790. there is nothing more they could with that gpu since its pretty memory bandwidth limited. overclocking wont help much and the memory is almost as fast as gddr5 can go at this time. the slightly faster gddr5 that is in production would be too expensive and still not make enough difference to warrant calling it a 5790. it would have to be a 5830 to fill the gap since the 5800 series can easily be cut down more.

Maybe we will see 7 Gbps GDDR5 memory on HD58xx refresh when GT300 debuts.

Those higher price points obviously give manufacturers more leeway with using expensive components.

But yeah....I think 7 Gbps memory would help equalize some of the bandwidth shortfalls on the otherwise strong Juniper Core.

you said this before and it is still is not going to make sense. they are not going to put the most expensive memory on a card of this level. 7000 isnt even close to being available and certainly not cost prohibitive when it finally does get produced. cutting down the 5800 series to make a 5830 is the only logical thing that will happen.

When GT300 releases.....it will be better than HD5870.

Assuming there is potential for gains in performance from more memory bandwidth on 1600 sp/256 bit- I don't see why ATI wouldn't want to use better memory?

How much more expensive is 7 Gbps memory compared to 5 Gbps? Everything is relative. For example, even if it is 2x to 3x more expensive....it could still make sense to use it if competition from GT300 truly warrants its use.

you are not making any sense now. you were talking about the possibility of a 5790. the 5700 cards are not competing with gt300. 7000 memory is not even being produced yet and even 6000 was in way too limited of supply and too pricey to be cost prohibitive on the 5800 series not to mention 5700 series. there will be no 5790 with 7000 memory. they will make a 5830 to fill that gap between the 5770 and 5850.

Last time I was talking about HD5790 was when I thought it would be 1120 stream processors. (that was a while ago.)

These days I agree something like HD5830 makes more sense. I'm sure ATI has a lot of defective and/or lower binned cores to do it also.


But what about competition from GT300? In that scenario using 7 Gbps memory might be attractive for ATI with regard to HD58xx refresh.

they dont really need that fast of memory. the 5850 and 5870 are not very bandwidth limited. we will likely see a 5890 with faster clocks and memory if need be though.

Has HD5870 ever been tested with better memory? A few reviews have said the card doesn't really scale twice as fast as HD4890.

thats not just because of memory. firingsquad tested with different memory speeds and the impact was not that great.

But would overclocking the memory beyond spec be the same as using faster stock memory (7 Gbps stock memory vs 5 Gbps stock memeory). Notice what Virge has to say near the bottom of this page.

"I would be careful with high memory overclocks. If the AT 5870 article is right, the memory bus isn't error-free too far beyond stock, which means they may actually be hurting their performance if the card is constantly retransmitting to correct errors."
