Where are all the 1GB 4870?

[dennilfloss]

I'm tired of waiting. :frown:

Gimme a factory-overclocked one with fancy cooling STAT!!

 

[Creig]

Well, overclockers.co.uk has them available for pre-order, so I would imagine full release worldwide can't be too far off.

 

[dennilfloss]

That preorder has been around for over a month.

 

[marrr]

Im waiting for one of these also..

 

[SSChevy2001]

I'm with you, what's the big FN holdup for? Put the RAM chips on the board and send it out already ATI

 

[Hauk]

Nice supply of 4870 X2's out there. That was priority #1. Gotta sell those 4870 512's at max margin for as long as possible too.

They're probably timing it for GT200b. Not that it's direct competition, but ATI seems to have learned a thing or two about stealing thunder..

i got tired of waiting

my $469 4870x2 arrived today ..

does anyone know off hand if a core can be disabled? So i can test it like a single 4870/1GB?


i probably have to buy one anyway and sell my 512MB version
for Xfire-x3

i'm off to test and review

aloha

VT has a nice little bundle this time
- looks like Prince Of Persia, The Two Thrones is a full game and the Trilogy Trial for Guild Wars is also included [i have GW already]. There is also a Ruby Demo. i get *nothing* with Sapphire

TechPowerUp was able to disable 1 core on the 4870x2. Love to see another review though, if your up to it.

In order to get scores for single-GPU HD 4870 X2, I disabled one device in Windows Device Manager

Not bad on the BB pre-order! That darn thing was posted hours after I pulled the trigger on my X2. I'd much rather have that Visiontek. Oh well. Enjoy the card.

Despite what GPU-Z will report, the fan runs at 27%. A 40% fan speed will make a world of difference. I have a lot of air blowing on the card which helps. At any rate, those stock idle/load temps can be improved...

Thanks .. i thought so
- i don't have to bother getting a 1GB 4870 right away

yes, i was surprised by it coming thru rather quickly. That is the 2nd VT i got from BB; the other was 2900xt with OB for $330 just after it launched

mine started to artifact in 3DMark06 [at 800/1000] - upping the fan's speed cured that. Almost 14,800 .. so i need a CPU upgrade; 3.33Ghz is way too slow

a new mb also for PCIe 2.0 [and full x16 x2]
:roll:

 

[dennilfloss]

Still a no-show but it gives us an idea of what the prices will look like.

This one looks nice.

 

[Sylvanas]

The 1GB 4870's sold out at the major stores here in Aus over the past 2 weeks, due back in a few days, can probably still find them if I looked around- I am sure they they should be arriving worldwide soon

 

[taltamir]

disabling one core is not a clear indication, it still lost to the 4870 512MB on occasion because it is limited to half the PCIe bandwidth due to the on board splitter. while other times the extra ram compensated enough for it to win.

the stock clocks on the x2 are lower than the 4870
- i'd say disabling a X2's core will give you a good indication of a 1GB 4870's performance at 800/1000 [my max stable OC with CCC]

Don't you mean higher?

actually they are pretty much the same
-the difference being O/C'ing with CCC

my 4870x2 is 750/900 .. you can OC in CCC to 800/1000
however, 4870/512M is also 750/900 BUT you can OC it to 790/1100


i bet you can OC them the same IF you can keep the X2 cool; it is clearly much hotter than a single 4870 and my X2 artifacts at 800/1000 with the VGA fan at stock.

 

[dennilfloss]

My bad. I thought most X2s had an 800 default core clock.

 

[Cheex]

In any case, I don't think anyone should run those cards with stock fan speeds. I've read that there is a way to increase it and I think you should. Sacrifice a few decibels for a cooler card, system and room

my bad also

i never work with the stock clocks anymore
- i had to look

i am just finding i can easily OC the 512MB-4870 and not so easily the X2 without the fan noise becoming noticeable.

Yes, Cheex - agreed; use a tool like Expertool. You can keep the noise down and still have a cooler GPU.

 

[hybrid2d4x4]

Thanks for the links, dennilfloss. I didn't notice that directcanada put up some 1gb cards, it seems that they're getting closer to release! If only they didn't carry a $100 premium over the cheapest 512 version...
With a GTX260 for only $240 after rebate, I'm almost tempted pick one up rather than keep playing the waiting game, even if my mobo favors ATI with the prospect of CF down the road.

Nvidia should be releasing GT200b should be release soon. At the very least the should be some better deals coming soon for GTX260 and 4870 512MB. The only high demanding title that's coming soon are warhead and far cry 2, so you got till the sep 16th.

 

[Creig]

I wouldn't pay any more than $30-$35 over the price of a regular 512MB 4870.

 

[hybrid2d4x4]

I wouldn't either. 10-15% is as much premium as I'm willing to pay right now. But if they keep the prices up I may just have to cave. I've already had an otherwise complete system collecting dust for the last 2 or 3 weeks and my patience is wearing thin.

Its a switch, not a splitter!!! You shouldn't try to make things what they aren't.

Wont be surprising if the inconsistent performance is related more to the drivers than the architecture.
