Graphic Cards ATI 4890 Review - HardOCP

List of all HD4890 reviews
List of all GTX275 reviews
Lots of pictures for the illiterate
But what Radeon HD 4890 is really good at is overclocking. We have every reason to say so: even without any special tools and tricks we managed to raise the GPU frequency to 1GHz! This height has definitely been conquered easily, because as you remember, it used to be impossible to overclock a Radeon HD that far without any hardware modifications increasing the GPU voltage. Overclocked Radeon HD 4890 not only proved capable of competing successfully against GeForce GTX 285, but left the rival behind in majority of benchmarks

its not 40nm , its 55nm :rofl:

overclocking memory hardly gives gains on 4890 .

gtx 275's shader overclocks above 1600mhz and can be overclocked further with evga tuner so it will beat even gtx 285 after overclock . . and ATI driver support is really great :rofl: thanks to the driver support that i decided never to get ati again :no:

and even with 55nm blah blah, card wastes 30W more at idle copared to 260, most of the time people dont play games and PC is idle, so its very expensive in long run :no:
 
Oops :p 40nm product will follow soon :p Yea its 55nm..

Pathetic driver support is what all ATI products have :| nvidia release plethora of drivers and fixes for their cards which makes it a nicer choice.. They even failed to deliver OpenGl 3.1 and Xorg 1.6 support till date can't even expect XVBA from ATI :mad: Next upgrade would be definately nvidia :)
 
I dont like ATi also, I have Toxic VaporX Copper heatpipes version, core runs cool @ 40s idle and max @ 60c load I have seen, but so much heat rise from PCB (effects Nb and CPU temp), increased temps inside case, never experienced same w/ Nvidia card.

XBitlabs is particularly generous

ATI Radeon HD 4890: 1GHz Conquered! (page 16) - X-bit labs
 
seriously guys after all this..feel like switching loyalties, from my 1900Xt, 4850 and now current 4870, itching to try out the GTX 275/285, they have lower power consumption too. What do you guys think worth the switch from 4870 512mb version?
 
what the hell is wrong with AnandTech nowadays. first they gave a marginal victory in "conclusion" to GTX 275 even when in most benches at the site, 4890 was ahead of it at most settings/resolutions.

Now they have changed it. The victory/winner word has been deleted and the conclusion summarizes the article in a better manner now.

Most surprisingly, AnandTech benched 4890 with 8.12 Hotfix :no:

AnandTech: ATI Radeon HD 4890 vs. NVIDIA GeForce GTX 275

Edited: Anand Lal posted in comments later

Hey guys, I just wanted to chime in with a few fixes:

1) I believe Derek used the beta Catalyst driver that ATI gave us with the 4890, not the 8.12 hotfix. I updated the table to reflect this.

2) Power consumption data is now in the article as well, 2nd to last page.

3) I've also updated the conclusion to better reflect the data. What Derek was trying to say is that the GTX 275 vs. 4890 is more of a wash at 2560 x 1600, which it is. At lower than 2560 x 1600 resolutions, the 4890 is the clear winner, losing only a single test.

Thank you for all the responses :)

Take care,

Anand

I was surprised too, after reading AT review... I mean literally I was like WTF.

Just to be sure, I went through all the pages again, checking all the charts/graphs and I could not get my head around the conclusion page.

If they have fixed it then good... but most the of people, who were awating reviews for both the product on launch date must have read the original article the way it was.

looks like 8800gt vs 3870 all over again,though this time there isn't any clear winner(the results are all over the place) and gtx275 might never end up selling as voluminously as the 8800gt.

i don't think so, 3870 didn't perform par with 8800GT and here 4890 is indeed better over 275 @ 1650 & 1920 as AT mentioned later on.. AT 2560, i think, its all upto driver guys to make it further better. :)
 
As far as mainstream gaming is concerned, not much people play at 2560 so IMO 4890 has kicked nVidia's butt seriously hard. On par GTX 285 performance ( if not at par, around 95%) for much lesser price. $350 against $ 240
