Overclocking Extravaganza: GTX 275's Complex Characteristics

Power Consumption
At Idle, the GTX 275 does very well, drawing less power than all the other boards we tested, even when overclocked.
Crank up the load, however, and the GTX 275 becomes a bit of a power hog. Overclocked power draw is higher than everything else we tested.

Actually, you can save as much as 40W(!)idle when you underclock a 4890/4870. The important part is to underlcock the GDDR5 which automatically adjusts voltage too.http://www.computerbase.de/news/hardware/grafikkar...">http://www.computerbase.de/news/hardwar...ten/ati/...

Anyway you could translate the 4870 portion? Babelfish is not working for me for some reason....jeramhyde - Thursday, June 4, 2009 - link
great article thanks :-) good work with the graphs and setting it out in an easy to follow way :-)my housemate just got a gtx275 today, so we'll be trying those overclocks tonight :-)

Alright, I just spent the last 10 minutes looking for a 900 shader 4980 before I realized you meant a 900MHz 4890. It's wrong in every graph.DerekWilson - Thursday, June 4, 2009 - link
It's not wrong, it's just noted in a different way.like I say (702 core) for the GTX 275 with a 702MHz core clock, i say (900 core) for a 4890 with a 900MHz core clock.
I'm sorry for the confusion, but it the graphs were already so crowded that I wanted to save space as much as I could.

no, you're not getting me. It's listed as a 4980, not a 4890. I thought it was a new card, the "NEXT TIER" if you will. The 900 I thought might be a reference to the number of SP. Once I realized you just transposed the numbers, I got the 900 was MHz.DerekWilson - Thursday, June 4, 2009 - link
oooooooooooohhhhhhhhh ... okay ... that's a fun typo. I can't really do search and replace on these graphs either. I'll try and get it cleaned up as soon as I can.thanks for clarifying.

Very nice article as always! :)GTX275 and 4890 is really evenly matched in every different way(Price, performance, overclocking performance etc) except for the fact that 4890 can be used with the 19$ Accelero S1:

, which makes it totally quiet and cool. Just watch those VRM-temperatures and you will be just fine!
This is the main reason why I chosed the 4890 over GTX275, and the fact that I had a CF-compatible motherboard.
By the way, why didnt you include the 4890 (1\1.2)GHz idle power draw? Or is it just a little type-o? :)
Request: GTX275 SLI vs 4890 CF (And overclocking bonanza! :)))))

I can't help but use google and check the very first site that comes up:http://www.techspot.com/review/164-radeon-4890-vs-...">http://www.techspot.com/review/164-radeon-4890-vs-...

and the GTX275 beats the TAR out of the 4890 !!!

I guess derek has once again used some biased bench or the special from the manufacturer 4890, and then downclocked the GTX275 to boot.
WHAT A CROCK !

It's hilarious - the extravaganza overclock they do here for Nvidia can't even match the stock timings of a common EVGA.http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...

core 713 derek weakness red rooster nvidia hate 703
So what AT has done here is put the 4890 max overclocked in their other article against a low end stock gtx275, then in their extravaganza overclock gtx275 they put up a pathetic overclock that is BEATEN BY An EVGA gtx275 as it arrives !
Worse yet, they jammed their ati 4890 maxxxxx overclocks in for comparison !
------------
How to be a completely biased load of crap by Derek and AT :
max overclock your ati 4890 and put stock gtx275's against it
weak overclock your gtx275 and put maxx overclock 4890's against it
___
ROFLMAO - I HAVE TO LUAGH IT'S SO BLATANT AND PATHETIC.
