    The core shown is Juniper: a derivative of the Cypress already launched but not the same according to AMD slides we have already, unlike the HD 5850 which has two of Cypress's 20 SIMDs disabled. This is the only entirely new core preceding the Redwood and Cedar cores which will launch on the low end $100 mark early next year.


    I smell modding :3
  2. There is talk that ASUS will do a voltage adjustable one as well :D Modding/ Overclocking here we come. Im a bit upset that the reports that teh bus would be 192 seem to be unfounded though :( Guess that just means its a really good card and they had to do it to stop it compeating with a 5850 when overclocked ?

  3. Seen it before and i think we both posted that one the same night as i remember seeing it after i had posted it within another thread to show JDJ that the card being tested was a 5750 and not a 5770.

  4. Oh yeah, I remember that little quarrel..

    So it seems the 5770 can be OC'd to a 5850, and hard-modded to a 5870?

    It's a completely different core, no unused SIMD to active. Though the 5850 might be moddable.

    No what i meant was that if they gave it a 192 bit interface it would be too cloce in performance to the 5850 so they cut it back as a way to hobble the card.

  7. Bit tech pulled the link but concretefinish, another forum member posted this. http://www.tomshardware.co.uk/forum/271650-15-first-pictures-5770-leaked-early

    Looks like they ripped it from Bit tech

  8. From what I heard the card will officially launch on 13th this month. From the specs I guess the card will fit nicely between 4890 and 5850. If this is true this will be the best selling card from this generation IMHO :)
  9. Im just really concerned about the 128 bit bus, I wonder where Andand got the 192 bit bus from ?
    It all seems weird to me i mean why give a card 1GB of GDDR5 Ram when the bus will stop it playing at resolutions where thats going to make a differance anyway ? They could have made them cheaper by using half the ram.

    At 192bits+ 512VRam the 5770 would come close or become equal to 5850 with some OC at resolutions below 1680x1050. I think ATI wanted to give mainstream users a card which can play games at any resolution, but with lower FPS than 5850 all the time. This would put the 5770 firmly in the mainstream market and the 5850 in the mid-high end market, providing a good separation between cards. ATI wanted to avoid a 4770-4850 situation.
  11. Yes i understand that and posted as much just above you, Its just stupid to see a card hobbled like this. If the card can compete with a 5850 given a decent bus then why have a 5850 at all ?
    I have seen some benchmarks and am looking for more but what i have seen so far have been 4670 1GB vs 512 versions and there is just no differance between the two even in Crysis.

    More cards, more profit. The 5850 and 5770 will sell at different values providing ATI a foothold in every market. I see the 5770 card be bought by people who want performance for little cash or by people who want to OC the **** out of it just to come close to the 5850. The 5850 will be bought by people who want performance at higher resolutions and want to OC the **** out of it to come close to the 5870. :lol: . So everybody is happy, espcially OCers :sol:
  13. Hopefully Nvidia will bring out something with similar price and performance and only needing 1 pci power connection each....Ive got an SLi mobo and 600watt (with only 2 PCI-e connectors) and dont want to have to overhaul the system just yet...maybe able to get away with 2 of these in SLI :D (probs much better performance than a 5850 for same price!)
  14. So it seems its 800 sp's after all. That will put it just behind 4890 by my opinion. Why?

    Because its specs are exactly as 4890 except the memory bus. Still dont know the count of the ROPS/Textures but as they go bundled in stacks I would suppose same as 4890.

    I think thats why they ended up with $159 price tag. If it was faster than 4890 it would be priced more closely to $200 mark

    so my guess is 5770 = 4870
    and 5750 = 4850

    the 5750 with 512 MB ram is especially tasty with $109 mark. Yummy

    So nothing to do with the screen shots rangers posted that have it performing slightly behing a 4890 then ?

  16. Does anyone know how the 108W/18W Power consumption at Max/Idle Power for the 5770 compares to the 4890 or 4870? The only power consumption numbers I can find for the 48**'s is for total system consumption at the outlet, but I’m not sure where the pictures from my post above is getting the 108W/18W numbers.

    Very very favourably is the answer to that http://www.xbitlabs.com/articles/video/display/radeon-hd4890_6.html#sect0

    Thanks, that is exactly the comparison I was trying to find. So it looks like the 5770 = 4850 in power consumption. That will be perfect for my needs.
  19. HD 5770 is currently listed as $289 in Australia. Supposedly in stock too.
  20. Might wait on this launch to see what the benchmarks say when run under a retail W7 and DX11 environment.

    Mactronix
  21. I will bite the bullet and say the 5770 will be better than the 4890 with a slight OC. :sol:
  22. The 5770 listing has been pulled. :(
  23. Releasing the 5770 now makes no sense economically tbh. Hell we're only just seeing the real launch of the 58xx's.
  24. It's shown up at 3 more stores now, the cheapest is 250 AUD (~203 USD after removing 10% GST): http://ijk.com.au/branch/ijk/product_info.php?cPath=353_340&products_id=123053

    It should launch at no more than 199 USD then.
  25. As i said I'm going to wait and see, i tend to agree that the 5770 could end up being the best thing that's not really worth having from a VFM point of view, but as i have also said before its all going to depend on Price perf at the end off the day. In certainly not going to lay out around £100 just to get DX11. I don't know what price its meant to release at over here in the UK but i will be quite happy waiting until its about the same as the 4770 if need be. Don't see why it should be any more, in fact its probably cheaper to build.

  26. Any news from retailers when we will be able to order one of these? Even though there should be more of these at launch than the 58**'s, I wonder if they will be hard to find.
