One of these is not like the other \/

Including NV's driver problems in 4k, what about the 2D performance smoothness difference? What about the fact the cards are smoother than the titan sli, and offer noticeably more performance? Seems kind of selective in what you don't want them to overlook.
Almost every review talks about the higher power consumption, as well as the operating temperatures. It's not like they leave them out.
They still throttle using Uber mode. 290X's that don't throttle are coming though. I wonder how they'll perform?
You have more information to add? I'm like a sponge I'll soak it up.
It's not so much a lottery problem as it is a cooler problem, it's already 95C at 40% and 55%.
You'd have to ask Linus if they put in ear plugs to run the card at 5500 rpms to test viable overclocks.
Source?
I'll wait for aftermarket and OC models to hit before claiming anything like most people. The reference cooler is likely limiting things ATM, unless you want a blow dryer in your room.
Source? All reviews I've read see the 290X at almost always at 1000 MHz in uber mode. Nvidia cards on the other hand are at about 850 MHz or even only base clock at default settings and also at their maximum boost bin with 94°C temp target.
With 15 minutes pre-heating:
AMD: https://www.computerbase.de/artikel/grafikkarten/2013/amd-radeon-r9-290x-im-test/12/
Nvidia: https://www.computerbase.de/artikel/grafikkarten/2013/test-nvidia-geforce-gtx-titan/19/
This. I would love to see a survey of what resolutions 290x users would be on 6 months from now. Have a feeling the majority would still be on 1920x1080. :biggrin:Too bad 4K is hugely irrelevant. By the time it is meaningful 290X will be a distant memory.
TechPowerUp
TPU said it stabilized at ~900MHz in Uber mode.
[H] showed a marked improvement in FC3 by increasing fan speed above Uber. I know that's a bit anecdotal, but throttling is the logical explanation.
Which is weird since Linus did 1440 reference 780 vs reference R290X OC vs OC and the 780 won every test.
AMD is clearly playing the reviewers like a fiddle, I imagine the reviews read similar to the marketing material that comes with their cards.
Ah..its the reviewers that are the problem...thanks for clearing that up.
TPU shows a 8% performance on average difference between uber and quiet mode across many games. If uber mode already throttled then quiet mode would throttle even more - especially in CF configuration.
The two results of [H] are not conclusive. TPU, Computerbase, HT4U all showed a near 10% difference between quiet and uber mode in their large test suites with the most demanding settings they tested (1600p). We also don't know if [H] starts their benchmarks immediately or if they pre-heat ingame.
Fact of the matter is that using uber mode leads to less throttling on AMD cards while using the default settings on Nvidia cards leads to significant throttling. Clock for clock (both cards reach about 1 GHz turbo if not constrained by temperature) Titan and 290X are pretty close if not dead even. Only in the most demanding settings does the 290X manage to pull a bit ahead.
So another biased review (like Kitguru and Sweclockers):
Nvidia cards are tested at default (throttling down due to the 80C temp target)
AMD cards are set from default (quiet mode) to uber mode (allowing higher clocks)
Find the error.
290X default mode is Uber mode.
Uber mode is not like the 6990 ausum with stickers saying it would void warranty if moved.

http://www.techspot.com/review/727-radeon-r9-290x/Speaking of which by default the R9 290X runs in what AMD calls quiet mode
http://techreport.com/review/25509/amd-radeon-r9-290x-graphics-card-reviewed/4The 290X stays at the 1GHz Boost clock for most of the period, but near the end, with the default fan mode, its clock speeds begin to fluctuate, ranging as low as 943MHz for a moment. With the higher fan speed in uber mode,...
We both know if the roles were reversed you'd be playing on the other side of the field.
It's like doing a 7970 vs 680 review, except Nvidia released the 680 with a 170w bios and a 240w bios with a screamer fan and reviewers didn't even bother to overclock the 7970 to compare them.
Right now Nvidia has the better coolers and the better overclocking cards because of their already to market advantage, and yet we have to go through review after review of uber bios selected and stock Nvidia products.
It was a smart move by AMD, and many reviewers are just sad. It's a good thing we have fresh blood like Linus which always tests overclocking. Sure showed a lot of people how good 7xxx series was compared to Nvidia counterparts with all their overclocked reviews.
In the Linus review at 1440p the 780 is faster, clocks are +125 +300, so not even a big overclock (netted them 1110 core), R290X was at 1050/1300 /w 70% fan speed.
No, default is quiet mode. In every review it says that.
Except the roles aren't reversed are they?
So that's a non-starter.:hmm:
No, default is quiet mode. In every review it says that.
Uber mode is a default mode of the 290X so is the quiet mode.
Good luck with that telekinesis...but wait...that would also be user intervention. I guess you need to wait for some poor dud in a factory to make a mistake and set the uber mode. Then you can call it default.A default, in computer science, refers to a setting or a value automatically assigned to a software application, computer program or device, outside of user intervention.
I think 6db is (very) roughly a doubling, so yeah it's big. Aftermarket coolers will hopefully improve this a bit.
Nvidia gets lambasted for Fermi, praised for Kepler... AMD gets smart offers "silent" and "uber" bios and nobody puts much stock in the fact that these are the hottest, loudest, and most power hungry cards we've ever seen while posting the results.
AMD outsmarted the reviewers imo.
As long as more power = more performance, and performance/watt is good it really doesn't matter. Nvidias stock cooler is clearly better than AMD's, so waiting for an aftermarket cooler seems essential for the 290x, unless you plan on doing it yourself.
Very impressive on AMD's comeback in the crossfire department. That scaling is very impressive, 512 bit bus really coming in handy.
Sure they are, if uber mode was acceptable they wouldn't have shipped quite mode.
Based on the way the card works it is basically an overclocked bios.
AMD peaked the card with a bios switch, then reviewers compared 180-200w stock cards to 260-278w "uber" switch cards.
Well played by AMD, though it is becoming more and more clear why we aren't seeing OC vs OC reviews. Linus only managing 50 MHz on the core at 70% fan should be some indication of this, even stating that they could go higher but the card would just throttle and be slower.
Wishing well.
You mean me?
I'm pretty much the only one claiming that 780 OC is more or less equal to R290X OC at relevant resolutions. All my information indicates a slight advantage to the 780 but nothing to write home about.
I guess time will tell :|
