[HardOCP] Asus DC II 290X max overclock versus GTX 780ti max overclocking review:

Page 14 - Seeking answers? Join the AnandTech community: where nearly half-a-million members share solutions and discuss the latest tech.

If I'm reading that right, the 780 with a 170Mhz OC beat the stock 290X but lost to or tied the 1115Mhz 290.

We're really re-hashing this again, I just want to point out that the term average is a discrete value so you have some funky stuff going on here with the "average" being 15-23%, just to remind you, average is not a range - it is a discrete absolute value.

I know you love AMD, and that's cool, but you're continuing to put them in the best light possible. I don't understand WHY you're doing this, but at the same time, there is nothing wrong with that. Hey, we all have our preferences. I like nvidia is far better because of intangible factors and features. You like AMD. Whatever man, that's how some roll, nothing wrong with it. But I don't agree with your assessment at all. I mean, i'm looking at overclocked 290X reviews at Guru3d, hardwarecanucks, pcper, techpowerup, and hardocp and they are most CERTAINLY not averaging 23% faster for overclocked 290X cards. In fact, like I said, the definition of the word "average" is not a range. It is a discrete absolute value. So that brings up problem number one with your claim.

Furthermore, there are numerous reviews at the websites that were aforementioned and their scaling ranged from 6-10% above stock. 6-10% faster than Titan and 6-10% above stock. 6-10 % is not 23%. Now we have a pickle here, huh? The stock 290X is even with Titan or within 1%. 6-10% above stock is certainly not 23%. An average is a discrete value, I should remind you.

How about we do this. Which websites do you look at? I look at techpowerup, hardwarecanucks, hardocp, pcper, and guru3d. Like I said. Aftermarket 780s overclocked basically blow away the overclocked 290X at the above websites. I don't know what kind of funky stuff your'e doing to think that a "range" of values is an average, that violates the definition of the word average itself, or what websites you're looking at.

I'll tell you what we CAN do. With all due respect, I think your assessment is wrong. I do not think Hawaii overclocks that well. But, if you want to debate this further, you suggest which of the above review sites *I* mentioned that you like. Look at my list. And you can suggest your own. Maybe we'll do a sample of 10 or something. Because I think your assessment, no offense, is wack. Then we can look at overclock values and do some absolute math without an "average" suddenly being a range of values. Like I said, a range violates the definition of "average".

So you suggest the review websites that you like, not including kitguru (AMD sponsored and only tests AMD GE games). I like the above websites because they test a mix of both games sponsored by both nvidia and AMD. I already named mine. And we'll look into this further. My list again is HardOCP, PCPer, hardwarecanucks, guru3d, techpowerup. All of these websites test a wide variety of games that aren't necessarily all AMD aligned. Unlike kitguru. You name which review sites out of above you like. And suggest your own. Then we'll agree to a testing methodology.

Gee Blackened, I don't think I got your point the first 7 times. :biggrin:

I did use the term average erroneously. I gave a range instead of a single number. The average across the four 290X reviews was 18.9% faster than a Titan although one of the reviews was of a non-oced aftermarket 290X.

If you'll notice, the majority of the reviews I linked are from your list. I looked for reviews at PCPer but they had no overclocked results when I was looking. I'm not sure where the debate is since the reviews I found are from well-respected sites that you even said would work fine.

Is the debate with the numbers I calculated? Feel free to go through and make the same calculations. If I made a mistake, I'm all for correcting it.

Yep, same reviewer that had the 290x at 1130 slightly beating the same 780.

Obviously both can't be right, 290x can't be 20% faster than Titan unless a mild 780 OC is as well.
 
What's the problem. I'm suggesting we look at review websites that all parties agree to as being objective, and websites that do not heavily tilt their game selection to one side or the other. All of the websites i've named do not test AMD only games. So if we include a website like FZ or kitguru, they only test AMD GE games.

What's your worry here buddy? Ii'm only suggesting a testing method that is agreed upon. I think his results are wack. And his definition of average is clearly wrong, because an average cannot be a range. Unless my mathematics knowledge is failing me. So what review websites do we both agree upon as not being wack.

Yes, I do prefer nvidia. Thanks for stating the obvious. You love AMD. You love to mine. As I said I don't care. I don't think there's a problem with that. I have a problem with the results which I clearly think are skewed. I think the assessment is wack. Because at the websites I named, overclocked GTX 780s are blowing overclocked 290X cards away. So here we have a pickle.

What are you worried about anyway?

I have AMD at this time for mining, but I follow price/performance and have no problem switching companies, I'm not attached to either one. I've owned multiple NV and AMD cards in the past.

I think hwbot is the best indicator of OC's we have and therefore the comparison should be at those clocks.

wand3r3r your hwbot numbers are beyond stupid, why would you keep reposting them?

You can't take old reviews and then try to figure out the performance of those cards against new reviews with your new favorite card.

Drivers, game updates, testing methods, a lot can change.

Because you disagree with the clocks = stupid? Exhilarating. 🙄

You follow price performance? Hey that's cool. Nothing wrong with that. Question though. When did you buy your 290X cards? Just curious. Your other thread seems to indicate that you bought the cards in early January.

So was it price performance? I'm just making sure I understand what you're 'implying here. You're in the states, right?

I was trying to debate but to me it "feels" like the crossfire noise at 55% was around the same level as the GTX 690 with the titanium cooler at around 1200-1250 core.

I just saw that statement. Without going into details except to say that i've used the 690 and 7970CF - the 7970 has the same fan design as the 290X - I just want you to know that I partially spit my drink out from busting out with laughter after reading that. All is well though. My ipad was not damaged by my drink. 🙂 I'm not sure what the laughter was about. Just spontaneous. I don't know.

No, the clocks are stupid weather I agree with them or not is irrelevant to how stupid they are.

Probably about the same time he could have gotten a 780 Lightning for $500 or a Classified for $530 or a Gaming for $470, but wand3r3r likes reference noise even if it was lower perf/$ there is value in AMDs weedwacker reference design.

That's the Russian arm of Xbitlabs, they are very respectable so its good to see a more recent head to head.

I can't find spec on the 780 boost clock but its got a +170mhz offset. Where do you think it will boost to when its default is up to 960 (from that article).

Because whatever it is, I am seeing an R290 (not X) at 1115 beating it overall (except for M:LL with physx on and sniper elite where the 780 won big).

1130 or thereabouts.
 
Well, Maxwell architecture is done according to rumors. Nvidia is starting with mobile, though, as that is the most important segment. Not quite sure when the high end desktop variants arrive, but the chip designed to be used by ultrabooks - the GM117? I think? Is also going to double as the GTX 750ti.

I suspect nvidia won't peep a word about it until it's ready for launch. That's normal practice as far as I can tell, because announcing a release at this point would simply cannibalize their own sales.
 
The HWBot's numbers seems suspect because of the reported memory frequencies for both brands...

Yeah the HWBOT numbers are beyond suspect. I mean they're getting worse overclocks than most air overclocks by review websites - and these are the guys that overclocking to the limit? And the VRAM data is just completely incorrect. So if i'm to believe HWBOT, the guys that do LN2 overclocking to the limit, their LN2 overclocks, when averaged, are worse than what average reviewers are getting on simple air reference coolers. Alrighty then.

I guess Kingpin missed the mark. He should be aiming for the 1100s with his LN2 overclocking.

Why not? All the reviews linked had oced aftermarket 780 performance in relation to a stock Titan. If there were any driver enhancements for the 780 since the time of those reviews, they'd have affected the Titan the same way since they're from the same chip family.

The new reviews showing oced aftermarket 290X results are also in relation to a stock Titan. The results for the Titan would have shown any of the driver improvements you're worried about so the comparison can be made. Doesn't matter if the 780 reviews are older.

Huh? The average LN2 results are: 1675/1903. You have to click on "Liquid Nitrogen" on the page.

Actually it's the other way around or more precisely partnership. Fcenter is major Russian Pc oriented magazine with retail branch and Xbitlabs just republishes their articles.
And the latest one puts OC 290@1115 on par with 780@1162 (basically vanilla GZ Edition).

Because your numbers aren't matching up, should be more than enough reason to discount them.

How do you figure the performance of the 1130MHz 780 in those reviews based on your previous reviews and your assumed Titan performance delta between it and the 780?

Something isn't adding up, I already made up my mind as to why... You can't have it both ways.

If I'm assuming correctly, the reason why you think the results don't jive is because of driver updates, game updates, etc? Would not those variables also affect the Titan in the same way? Any gains found in the 780 would be gains for the Titan as well wouldn't they?

For me it still comes back to taking 4 reviews as gospel against 20 others.
 
Perhaps a more blunt approach is needed.

You said. Avg 780 OC is 8-9% faster than Titan an the avg 290x OC is 15-23% faster.

The reviews I'm linking show the 290x and 290 and 780 at similar core clocks have a 2% advantage to the 290 and 4% at 4xAA 1600p with the 290x.

Only one of those can be right.
 
They can all be right, because it depends a lot on the games tested. If you pick M:LL or Batman for example, its going to skew heavy towards NV. Or if you pick Hitman or CoH it skews towards AMD, theres lots of games like that.

It's not one review against another though. It's 20 vs 4. If you had to guess which of those was right, which would you say?

I stated the average advantage of the 290X over the Titan as 15-23%. That's wrong, the average is 18.9% between the 4 reviews I linked. Do I really think across a broad range of games that an oced aftermarket 290X is almost 20% faster than a Titan? Not really, I think with an average overclocking chip it's closer to 10-12%.

My point in linking the 290X reviews was to cast doubt on various posters saying an oced 780 would crush an oced 290X. The various reviews I linked indicate that not being the case.

The obvious problem here is that the GTX 780 had a sample of 20 while the 290X had a sample of 4. Anyone dealing with statistics? Problem right there.

You can't compare different sample sizes like that. Funnily enough, the range was quoted as the 290X overclock result while the "average" was quoted as the GTX 780 result. And those 780 results included reference results. Did the 290X results include reference 290X? Of course not.

Obviously the entire results need a complete overhaul with same sample sizes for both. Your best 290X overclock, with AMD GE games tested, was around 20% faster than Titan. The GTX 780 overclocked with an aftermarket cooler is also generally also around 20% faster than Titan.

Shall I go into an extended statistics lesson here? Or will we just play stupid? Sample size of 4 versus sample size of 20. Sample size of 4 290X's with nothing but aftermarket cards, sample size of 20+ GTX 780s including reference cards. Or if someone wanted to skew the results a little bit, we could do a sample of the 4 best on the 780 side versus the 4 best on the 290X side. Who wins? GTX 780 OC by a landslide. It's pretty cool how statistics can be so easily skewed.

The results are skewed, as I thought. Now that we have more data we can do a more proper analysis though, with even sample sizes for both cards. THIS TIME we'll just include reference card overclocks too for both. Last time your results included reference for one side but not the other.

From recent reviews, it shows R290X at 1ghz uber mode have near a 20% advantage over a 780. Likewise, R290 at 1ghz (Sapphire Tri-X) have a sizeable advantage. So the 780 needs an OC to catch up, or custom 1ghz models that boost to 1.1 or 1.2ghz out of the box.

Its not that clear cut is it and its going to depend heavily on the game selection.

As it is, clock for clock, R290 is faster than 780, so a 780 needs an OC lead to match it. If we agree the average for 780 is around 1.2ghz and the average for R290 is around 1.15ghz, then its a close call.

And BTW, for the record, every other review site that tested R290/X OC found excellent scaling, even the xbitlabs one you linked. Going from stock to the 1115mhz clocks had near perfect scaling as is on the 780. So back to the OP, [H] has a DUD Asus R290 that is overheating and way too power hungry. Defective. Over all the xbitlab games (including crysis 3 which H has no scaling), they found stock R290 average fps going from 65 to 74.9 with an OC, for the 780 it went from 65.4 to 74.6, great scaling.

Oh how you conveniently forgot to mention that the 780ti in that chart, and the 780, neither are overclocked. The "max" used by computerbase is simply maxing the slides in precision which isn't overclocking. It is stock clocked.

Sample size of one. Oh man. I could take a sample size of ONE right now and show a GTX 780 OC obliterating the 290X by a mile.

Lemme just do what you're doing: Sample size of 1:

perf_oc.gif


Pack it up boys. 21% faster than Titan. 290X: 0% faster than Titan. Clear winner here folks.

Oh but hey. Let's overclock the 290X. Sample size: one.

index.php


Oh hey. 6% slower than the 780 OC'ed.

Looks like our sample size of one produced a clear winner in favor of the 780.

It's pretty awesome how statistics can be skewed . Let's just play stupid and throw in a sample size of 1. Or four. Versus sample size of 20 including reference cards.

So what websites are we looking at for proper overclocking reviews?

All of the reviews I linked had oced aftermarket 780s. Might want to read through the reviews before you disregard the results because they didn't match up with your expectations.

Oh hi there, maybe you missed my previous posts. I had said it depends a lot on the games tested by all these review sites and its going to vary review to review.

I thought maxing the slides to give it extra power was overclocking with NV's boost. It doesn't behave that way normally, it needs user control to tell it to boost higher.

I'm using Balla's own link to Xbitlabs, heaps of games included. Shows me that a lower clocked R290 is equal or faster than a higher clocked 780.

I don't care about the 780ti, I already said its the fastest OC, we're talking about the mythical 780.

If you are going to cherry pick as you claim I have been doing (which I haven't, since i've emphasized the point of game selection and different reviews) then nobody is going to believe your claims of 780 supremacy because then we can all play the cherry picking game too.
 
All of the reviews I linked had oced aftermarket 780s. Might want to read through the reviews before you disregard the results because they didn't match up with your expectations.

Go fix your sample size for both cards, IMO. Especially if you're going to make blanket statements about how the 290X overclocks to be so much faster than the GTX 780 OC. It just isn't a true statement. Best case, both cards are close to even when overclocked. Your original statement, based on a ridiculous sample size of 4 versus a sample size of 20, made it sound like the 290X was the clear winner.

It's easy to manipulate statistics when you lower a sample size. Let's do our statistics lesson for the day. As sample size lowers, accuracy lowers.

That's why news outlets, when they increase sample size, accuracy goes up. Decrease sample size? Accuracy goes down. So here your test has a sample size of 4 290X cards vs 20 780, including reference. 290X? Had zero reference.
