Meh to much money plus not much headroom without a volt mod.
Nice cooler. Although it shows that there is no advantage to having the extra 512MB there, it could be driver related or maybe they did not test it in situations that need that much.. I wish they had done grid.
Man, they coulda tested it on a newer chipset board.......:shakes:
Hi
i also received today the powercolor HD4870 PCS+ Edition but the 512Mb version !
i will start testing the card maybe tomorow !
regards
i have this card on pre order since 2 weeks now... :p:
Still 1GB has no advantage over 512MB cards.
Here's another 1GB Vs 512MB comparison on German website
GRID would surely benefit from 1GB at 2560 4xaa, with 2xx it uses 500mb @ 50fps but runs like crap at 15fps 4xaa when it goes over the limit.Quote:

I ordered the 512mb flavour and will be putting it under water. If i can pull off 900mhz core with modded bios , that will be sweet.
Dont think that is the case mate, when running high res with AA the 1GB card has a clear advantageQuote:

the cooling they put on the vrms of these cards seems to be severly lacking. If you plan on getting this card give the vrms some additional airflow at the very least
Different drivers, different harwre between platforms, bad game choice(both WiC and Crysis have performance idiosyncrasies that make the poor at representing general performance and FEAR is just to easy for today's hardware) useless "review"
I agree, 512 vs 1GB makes no difference for now.
Nice to see this beast finally see the light of day but what I really want to know is how 4870 1GB (and Crossfire) compares to 4870x2 in games that don't scale well. While it's nice to see ATi own the Crysis benches a broader pallet of tests and cards would give a better picture of the card's relative performance.
If there are any reviewers out there please could you do a comparison of:
4870x2 (and CrossFire)
4850x2 (and CrossFire)
4870 1GB (and CrossFire)
4870 512MB (and CrossFire)
4850 1GB (and CrossFire)
4850 512MB (and CrossFire)
with matched GPU/Mem clocks
on x48 with 4.0GHz (400x10) QX9770 & 4GB DDR3 at 1.6GHz 8-8-8-24-1T
vs.
GTX260 (plus SLi and Tri-Sli)
GTX280 (plus SLi and Tri-Sli)
9800GX2 (and Quad-Sli)
on 790i with 4.0GHz (400x10) QX9770 & 4GB DDR3 at 1.6GHz 8-8-8-24-1T
I have a theory that this SKU was held back to ensure that the 4870x2 looked considerably better than the 4870 512MB, the above tests would confirm this.
still why not just give it 2gbs for extreme measures and yes a 4gb 4870 x2.
why not put a spoiler on the heatsink while your at it, the results from doing either would be about the same.
meh... its doesnt have the same clock speeds on the 1gb vs the 512 card.. i didnt bother reading to the end of the test.
a bit expensive but it will go down when the competition starts to kick in
Wow, both ATI and Nvidia are so damn lucky that you guys do not really care about 1GB of memory. They might just as well make a 256 MB version and sell it for only $5 less, so that all of you suckers would buy it while they rake their profits in, thanks to your opinions that games do not need "that much memory, to boot."
Because of you guys, we're still not seeing 1GB on cards yet after having 512MB as something common for over 2 years. I've already experienced quite a handful of games that use over 600-700MB of memory on my 8800GTX, and that's at 1920x1200 resolution. Say, Bioshock, UT3, Crysis, Test Drive Unlimited, CoD4, the Witcher, etc.. etc..
EDIT---another thing about the video memory is that it also reduces the hitches/stutters. Most benchmarks out there do not show the minimum fps--it only shows the average, so the hitches/stutters would not show up in those graphs. Ignorance is bliss, eh? I think not!
That is some inefficient memory usage then. UT3 uses 350-400mb @ 2560*1600 for meQuote:

looks like a significant difference to me.
http://www.xtremesystems.org/forums/...light=4870+1gb
different games different effects; some (games) dont benefit from the extra ram and some will....but based on what little info at hand, maybe most games will not benefit from the extra 512 of gddr5.:shrug:
with respect, an 8800gtx is not a 4870 512MB or 1GB.Quote:

Well, I usually play with 4x FSAA on, and that significantly increases the amount of video RAM used. Most of the time, it's 16x CSAA with TR SSAA. TR SSAA increases it *a lot*, much more than just simple 2560x1600.Quote:

Yeah, thank God my 8800GTX has just enough (768MB) for most games released within the last 18 months! Using Rivatuner's monitoring, it's passed 700MB with 3-4 games but the memory usage kept on dropping after peaking somewhere so close to 768MB. It seems that the texture buffers were being "re-cached" or something like that, and I could notice some hitching in the game as confirmed with the graphs.Quote:

Sometimes, if our hardware does not advance for a while, the software development also stays stagnant. More often than not, software development usually follows hardware development. If Nvidia and ATI went ahead and marketed 1GB flavors of the 9800GTX, 3870/4870 right from the beginning, many of us would have already bought it, and more game developers would be encouraged to use higher-rez textures. We've been stuck at 512MB for like 2 years and then the "half-step" to 768MB for another 1.5 years. Remember Doom 3 released in 2004 "requiring" 512MB for Ultra quality graphics? That was 4 damn years ago!! Seriously guys, do you really want hardware tech to be that stagnant, unlike the past when we went from 16MB to 128MB (8x the amount) within 2 years between 2000 and 2002?
You can force it to use way more than 512 mb of gpu memory.512mb should be the min for Doom3,at least for Ati hardware.Quote:

Bad review : no games tested in 2560x1600, AF limited to 4X instead of 16X, too few games tested.
Today, with my 9800GTX, I sometimes encounter stutters when graphic memory is far above 512 MB : I play in 2560x1600, AA 0X, AF 16X, everything on max and on Obivion modded (QTP3), Stalker, Crysis, GRAW 2, Lock On, about 700 MB is used. And without AA 4X (Oblivion : around 1 GB : normal and BTQ maps 4096x4096, QTP3).

mascaras can you check the Vram consumption with RivaTuner during your tests :)
Hmm, I thought only Everest offered that so far. I've checked Rivaturner and do not see such an option. :confused:Quote:

From figures it preforms quite well when compared to other HD 4870 models.

Does HIS make ATI cards for Powercolor? I just checked my new card with GPU-Z and it shows that it´s a HIS(1787) card.:confused:

btw.
i flashed Powercolor HD4870 PCS+ few minutos ago with new Powercolor PCS+ bios !
no more strange noise when card is IDLE/2D with the Fan speed 2%
Now with new Bios the Fan speed in Idle/2D = 7% (53º Idle)
with new Bios max temp = 70º/71º with automatic fan speed (Atitool & Crysis Bench)
Fan speed in Full/3D = 43% most of the time :
55º - 60º >>> Fan speed 32%
61º - 70º >> Fan speed 43%
71º >> Fan speed 74%
when card reach 71º the fan speed = 74% ( only few seconds untill the temperature went down again to 70º )

If it is a product of HIS, one can trust the quality and the fan was very noisy.
My is under water and idles at 36~37°c and at load 41~43°c.
I will be modding the bios later in the day. Masacras why is your bandwidth just 64GB/S while my is at 121.6GB/S?
cause that 64gb/s is @ 500mhz ram clock. :yepp: 500mhzx4x256bit/8bit=64GB/sQuote:

Made by HIS, $341.99 looks very much stock (red color, standard dual-slot exhaust cooler, etc..)
Updates!!!
Here are some pics of the card with it´s cooler off;)
Shocker003 could you measure the hole spacing/size of the VRM sink?
I want to get a replacement when my card arrives, i have heard that the maybe the Thermalright HR-09U Type 2 fits. :up:
I just came back from work. I will measure and post the figure for you.Quote:

Two quick questions, does the Powercolor 4850 overclock better than the reference cooler models? Does it still use the reference PCB? Thanks.
thx, yup that helped. :up:Quote:

Powercolor HD4850 512Mb PCS+ is great card , personally i think is the best HD4850 (and the quietest one) and only cost +10$/13$ than the reference version !
regards
http://www.newegg.com/Product/Produc...70+1gb&x=0&y=0
Sapphire 1GB version IN STOCK, at only $314.99 definitely worth it over the 512MB version!!!!!!!!!!
Power PCS+ 1GB is listed at $324.99 but not yet in stock
http://www.newegg.com/Product/Produc...82E16814131123
is anyone reviewing the 1gb ver of the powercolor? its 20 bucks over the 512 model
and what is the general consensus of 1gb vs 512mb? is it only effective at 1920+ resolution? or is it not effective at all? i know G92 did not gain anything from the 1gb of memory, but would the R770's be the same?
The PCS+ is supposed to have 4-phase gpu power section. Not sure if the other brands do.
I know that the regular Powercolor 1gb model uses std 3-phase.
The 4-phase power does means that other manufacturers bios files do not work with the PCS+....I verified this on my 512mb PCS+.
Also, i don't think that reference full cover waterblocks work due to the different power regulation....although i would prefer to be corrected on this issue ;)
Diamond 1gb pretty cheap at the moment here.
Diamond Radeon HD 4870 750MHZ 1GB GDDR5 PCI-E 2XDVI-I Video Card $316 cdn... aka 300 USD
Anyone know anything about this?
Should these "PCS" cards be avoided now with this new revision?Quote:

Same thing have been reported locally here in Egypt , but out of 5 cards i have seen one of them couldn't run at the stock frequency provided by power color and was refunded , but yes it is supposed to be lower quality but for me it doesn't matter as long as it will run at advertised clocks (800MHZ core)Quote:
