Re: ATI HD 4870 & 4850 launch & price?

HD4850 is never meant to take GTX 260. bt its added advantage when it beats it in some benchs. 4850 is now somewhat a mid range card under 10k.
its the 4870 X2 thats supposed to take down the GTX 280 and GTX 280 SLI too[to some extend].

oh and he also said this-

a couple reasons that I'm going with nvidia over ATI. One I'm running an nvidia SLI chipset so if i ever choose two SLI the cards i have to run nvidia, and in general its always a good idea to match chipset to graphics card.... that is if you want your drivers to be stable. second, they just dropped the price of the 260 down to $299 which puts in my budget and only about $10 more then the 4870 plus it use's less power, runs cooler and push's about the same frame rate., and in a few months i will be able to buy another 260 to SLI them.

So i guess Nvidia is still leading in performance but ATI is better in price on performance, but not too much.

so its close game now both have almost same price and performance.

lets wait for the launch of 4870X2 than ATI will hold both PoP & best performance crowns.

4870X2 Preview
Doesn't beat the GTX280SLI

i can't be true 4870X2 has 2GB of memory.

What makes you say so?
Few 4850s come with 2GB or VRAM.

i MEAN THAT 4870 COULDN'T beat 280 in high resolution because of it 512Mb of ram & it is expected that with 1GB of of ram for 4870, it could come very very close in performance to 280gtx or even beat it because with 512mb of memory 4870 is just 15% slower tha 280GTX.

Re: ATI HD 4870 & 4850 launch & price?

^^Oh.. Yes I agree with that. If it comes with 2GB of memory then it will surely kick GTX280's a$$

guys ! any way to get 3dmark detail without going online ? i did the test but my card broke the record for the stove edition in this forum and reached 134 C , i tried to patch the BIOS but it vain

am getting 57FPS will ful details and 4 GB system RAM in Crysis , less or ok ?

 

[nvidia]

Re: ATI HD 4870 & 4850 launch & price?

^^
Thats HOT. My replaced electric stove went upto 127C!
And at what resolution did you play the game?
With highest settings and at 1280x1024 resolution, thats good.

 

[shantanu]

Re: ATI HD 4870 & 4850 launch & price?

yeah it was 1280 x 1024 ! i am praying that i get that FAn problem fixed soon

 

[nvidia]

Re: ATI HD 4870 & 4850 launch & price?

Oh then you're getting more FPS than what was there in the review in Anandtech. I think it was around 40FPS there.
And you better get the card replaced. Run ATi Tool and check your temperatures by running it for about 30 minutes.

This makes me think that some sites are not providing proper reviews.

Re: ATI HD 4870 & 4850 launch & price?

its on a little load, i play for 10 mins and get a warning by control center, about stability something , dont exactly remember, checked the log it was 134 C , daymn, i searched google and and Dominator told me there is a BOS problem which is having this FAN to run slow , so i emailed MSI and they said they will provide me with a official BIOS release soon , else they will Replace my card till then i am tinckering with the card BIOS lol !

 

[nvidia]

Re: ATI HD 4870 & 4850 launch & price?

^^Lol.. Cant you increase the fan speed from ATi Control Center or whatever its called?
Try to increase the fan speed from RivaTuner. I'm not sure if you can do that with ATi cards.

Woah! What card do you have, 4870/4850? Did you try increasing the fan speed? i run my 4850 on 70% fan speed and it idles under 50c and 65-70c under load

Re: ATI HD 4870 & 4850 launch & price?

@forever
i think uve got a card with newer BIOS. older one's fan speed is locked at 30% and cannot be run faster by ny means from any s/w.
which card have u got?

A Gecube 4850.

Re: ATI HD 4870 & 4850 launch & price?

If your computer still heats even after you increase fan speed to 100% just do what i have done, remove the cover of the case( many expert don't approve it ) or apply AS5 of the GPU core but for that you have to remove fan from the GF.

 

[dOm1naTOr]

Re: ATI HD 4870 & 4850 launch & price?

removing the plastic case wont help as the pushed air fails to run thru the fins nd might escapes from sides which fails the purpose,nd thereby reduce the efficiency of the heatsink. But applying a better thermal paste like AS5 or MX2 wud be better.
but do it as ur last choice, nd might void the warranty.
first see if u can get fixed bios from MSI or RMA the card with newer bios. or try to fix the fa speed by flashing it manually.
make a cone[with mouth diameter just higher than the diameter of current GPU fan] type out of X-ray film and use cellophane tape to affix it to the GPU fan and attach a 120mm fan to the cone and this might help i cooling untill the bios is fixed. actually it might be even more effective that bios fix, but will be uglier on looks.

Re: ATI HD 4870 & 4850 launch & price?

no reply yet from MSI ! i think i will manually tweak it !
