Performance seems to between an HD4850 and an HD4870 1gb although hopefully with newer drivers the performance will improve. Power consumption seems to be much lower though and is around the same as a 9800GT according to the review. This card looks great for an SFF build like a Shuttle based one.
Knew these were going to be good.
Roll on release date!:)
They would go well in a crossfire system :)
Does anyone know if there is a 5830 or a 5790 planned? The reason I ask is that there seems to me to be a fairly large gap in performance (and to some extent price, although less so) between the 5770 and the 5850 - A gap that currently the 4870, the 4890, the GTX 260, and the GTX 275 all slot into.
Maybe I'm wrong, but thats the way it seems to me.
Been waiting to see a review of these. Thanks.
So basically, go for these if you use lower res.
Think I will go for a 5850.
looking intresting, temps are much better, wonder what the cooler is like under the shroud.
Coolers and temps have always been ati's biggest issues.
Remember that's not just gpu reported temps but the PWM temps as well, on some of the 4850's the pwm is running hotter than the gpu because of the heat output and little in the way of cooling.
Has a nice reference cooler and I guess the performance is "ok" but not the best. But then again the temps are really nice and the price range is quite good too. Not sure if I'd upgrade to a 4770 or folk a bit extra and go for a 5770 in the future. I won't be upgrading before Xmas though so I'll wait and see xD
My crossfired ones are here.
My 4870s used to score 16k in 3D mark vantage, and wouldnt barely overclock at all.
My 5770's hit 960 / 1445 Mhz without a problem and score 18k, very close, if not better then 4890 performance, plus the lower power usage and only one 6 pin connector required for each (Before I had to use two molex splitters to use the 6 pin converters which I hated). I just needed to increase the voltage from 1.125 to 1.169 for complete stability at 960 Mhz using MSI afterburner.
So I have better performance on 2 x 6 pins, and yes, two of these 5770s is £50 cheaper then a 5870 and they outperform it in most games.
Heres my compare link:
http://service.futuremark.com/compare?3dmv=1521815
for 24/7 clocks, I use 950 / 1250, as the ram increase from 1250 to 1445 Mhz only gives like an extra 200-500 points. Overclocking the GPU = HUGE gains, but 960 is the max limit if you still want powerplay to work, and AMD GPU overclocking tool doesnt support the 5770s yet, but I'll be trying for 1 Ghz once it does.
I didnt really need to change from my 4870s, but 90 watt idle and 160 watt under load on the 4870s, down to 18 watt idle and 85 watt under load (maybe a bit more with the extra 100 Mhz) for better performance and DX11 is good, and I should be able to sell the 4870s for not too far off how much the 5770s cost.
If you dont like overclocking, then it wont be long before these start shipping with customized coolers and clock speeds of 950-1000 Mhz, at which point they will be awesome for the price, as long as they don't overprice them too much.
Also when Tri fire works on these cards, it works really well:

But in some games it doesn't work as well as normal crossfire, and most cases cant accommodate three dual slot cards.
1x 5850 = £200, 2x 5770s = £250, 1x 5870 = £300, 3x 5770s = £375, 2x 5850s = £400, 2x 5870s = £600 ......
In terms of cost, power usage and performance, the multi 5770 setups look very very enticing over the more expensive cards.

The 5770 with it's 128bit memory access is a pooch.
Here in the States you can buy a HD4890 for the same price that significantly outperforms it.
Yet that 4890 uses a huge amount more power and can't do Dx11. Bit like an nVidia card ;)Quote:

I've looked up that cooler, it's not just a copper base but a vapour chamber, like the one used on the sapphire vapor-X
I like the large ram+ power controller chip heat sink, means that if you did replace the cooler you could keep that on.
However it's using standard PWM (not the digital one found on the 5850&5870) which seems to have little in the way of cooling.
It's right under the blower so some air will be sucked over it.
The real issue for me is that the normal pwm system used on the 4850 & 4870 got very hot under load, often as hot as the gpu it's self, remember that the temp that's reported from the gpu is the chip only.
But all told it does look like ATi have finally got around to beefing up their stock coolers, which was always a weak point compaired to nvidia cards
