hm the morning debate, bottom right what does fixed boost mean, does that mean no boost?
i guess that makes the bench make more sense but we know how much a 7970 & 780 can overclock, no one runs them at stock

so its just going to come down to how much room the 290x has to overclock where it should really be on that chart

i can see nvidia releasing a overclocked(overpriced) 780 to turn it upside down

I think that means that a fixed boost clock was set to stop the core clock jumping around. Not sure really.

I am looking at it in the same way as a lot of non ref GTX 780s also beat a stock Titan until overclocking is brought into the equation.

They don't have to, the MSI lightning and EVGA Classified already take some beating.

You have to compare stock to stock though. I'm sure there will be similar non ref cards coming out for the 290/X 4-6 weeks after launch. Then it would be right to compare those to the non ref 780's.

lol they dont have to no but if they want to take the glory of fastest gpu back and make a new overpriced card at the same time

i think its likely, they will milk it!
like a goat!

Quiet mode: Less noise, more throttling due to +80c.

Normal mode: can be used as s leafblower or a Sauna substitute for average temps and no throttling.

My guess.

I don't know about anyone else but my Udders are standing to attention!

That bios thing makes me think overclocking must be very limited on air, if a separate limited bios is needed to keep it quiet.

Could be nice for water cooled cards though, switch into 'loud' mode. I want to see 1300mhz GTX 780 VS whatever 290X can clock to..

Its going to be just like Tahiti. You need to keep it cool if you want large overclocks. With a proper 3d party cooling solution, MSI, Asus Plat etc or watercooling id back a 290X with the fully unlocked bios.

Reference 780/titan are crap clockers as well, mostly down to the blower cooler. non reference is where the Mhz is at, same will apply to the 290's

i hear kaap has some evga nipple clamps, maybe he'll let u borrow them
he has 4 of them lol

What is more interesting than anything for me is the scaling between the HD 7970 and R9 290X, if you adjust the clocks back to 1000mhz the scaling is almost exactly 37.5%, the same as the increase in shaders.

Or putting another way find a game bench for a HD 7970 @1ghz, add 37.5% and it will give a rough idea what the R9 290X will do.

Interesting point. The performance scaling boost from core clocking a tahiti has always been impressive. A quick look at a 7950 @1100 will tell you that.

Come on Matt I am going to need some input, what are the best waterblocks to get for AMD cards, full length only though.

 

[LtMatt]

LOL. I'd be honoured to share his nipple clamps. Providing he washes them first.

Why would you ask someone who's idea of watercooling is owning a H100i?

They are self adhesive.

You know more about AMD cards than me.

Fixed Boost means that they set the max boost of the cards to nVidias "achievable/guaranteed" Boost speeds - the cards won't boost higher even though they could. The do it to make a definite performance baseline.

Btw you found a "no one" here ! I run stock clocks any day any time

Not necessarily true. Mine does 1250+/ 1800 .

 

[Jono8]

I'm guessing that for anything upcoming both AMD and Nvidia will push the idea of 4k as that's the next 'big thing' to sell more powerful hardware and more expensive monitors. It's not rocket surgery.

But that is ONLY good for the very small percentage of people that will be able to afford 3 or 4 of them and the monitor to go with it.

If you think one or even two 290x will be capable of playing next gen games ( i.e. games ported from the new consoles, new engines e.t.c) in 4k then your are going to be in for a shock.

For example, if they had tried Crysis 3 at ultra details at 4k they probably would have got about 10fps

But according to Broomstick all 780's do 1300?

I've no idea Kaap. I've yet to try to watercool anything. Its on my todo list though. Will likely have a stab at it when i upgrade to a single gpu when my 7950's stop cutting the mustard at 1440p.

Not necessarily true. Mine does 1250+/ 1800 .

Silicon lottery as always.

Could it heat a small family home?

Silicon lottery as always.

Of course but I was just pointing out that not all reference cards are crap clockers.

Could it heat a small family home?

Not really. It fluctuates around 85c on the default fan profile. 780s and Titan are made to run at this temperature on air.

 

[LtMatt]

Of course but I was just pointing out that not all reference cards are crap clockers.

Yep i didn't think they were. My MSI 7970 OC was reference and that was certainly a diamond in the rough.

Now if you'll excuse me i need a moment.
