mmm. You know Glimpse, your posts seem to normally look for some positive angle and I like that. But sometimes when you disagree with someone your posts get all personal and demeaning.
hi, Seeker, I have no problems with anyOne who disagrees with my opinion & as You noted I'm mostly possitive person (99%), but in Your case I can't help myself - maybe there's a reason for the tone? =)

Guys, I'm sorry to hear that, but specific tone was targeted to one user & noOne else.

Comparing CUDA cores to CUDA cores is what counts most when it comes to rendering speed. Some of us, after spending a lot of money converting to Octane got a real shock with the performance degradation between those two architectures.
"Some of You" should wait for solid results before upgrading - that's no brainer tip. if You haven't done so, that's no excuse to go around & blame nVidia or OTOY that You can not reach performance You were expecting..it was stupid move & that's it, swallow that & stop making false claims.
by the way, I don't have time to respond to Your questions/ideas as well & the only reason why I'm doing is to clear some thigns for others.
GTX580 had somewhere around 3.7TFLOPS of SP while GTX680 a bit less..~3TFLOPS..& that corelates nicelly with benchmark result (680 to 580, 63 to 52 in terms of OctaneBench)
Nvidia do not care too much about company with 150k users when gamers audience is counted in Billions..GTX line is meant for games. Nvidia done the move, marketed their cards for specific audience & it's not in their interest to provide You cheap cards for compute, as they sell Prosumer grade hardware for few times more.
Seekerfinder wrote:Of course Nvidia has to move forward with new architectures. But I will repeat that I think it should be a higher priority for any GPU rendering developer to engage their users with respect to new architectures, how it is being tested etc.
That's why nvidia offers Pro cards & once in a while skip an architecture or update that comes to thursty Gamers (where nvidia could sell little technological advancement, wrapped in code optimisations to reach better frame rates)..
again, OTOY done the best they could. & they pushed OctaneRender. There's no need to look for OTOY or anyone else blaming for Your ADHD. You or any other, should wait for concrete results before making purchase.
Seekerfinder wrote:So again, perfectly valid question. People need to make decisions on new rigs and if they know that there would be a degradation of a third of rendering power per core, that is not insignificant and will certainly influence purchase decisions.
Seekerfinder wrote:That is why I always find it strange to see a comment like "we'll test it as soon as we get one of the new cards". What guarantee is there that we don't get something like "Oh sorry guys, the new architecture turns out just not work great with Octane, but hey look, light fields!!".
680 to 580 goes 3.7 to 3TFLOPS or 63 to 52 in terms of OctaneBench is not "significant" at all..I doubt You would even notice a thing if You wouldn't see numbers under rendering screen.
Core count matters nothing if You can feed those cores with information & manage them effectivelly.
Let's give here simple comparison, realworld company. Just because You're going to employ more people to work on the same task & leave the same manager ontop, that doesn't mean more work will be done (due to inefective time/work managment). The same goes if You have too little people & overload them with tasks..discussion about cores is irrelavant as it's far from being single factor in performance.
Now the price..
Nvidia made a nice stunt during Kepler architecture days =) they sold 680 based on GK104 for gamers as update & left GK110 for Titan. Entirelly new line of cards that fill segment between Gamers & Prosumers. Then after some time they released GK110 based 780 with 3GB (& later with even 6GB model).
TitanZ came with stratospherical price tag of 3oooUSD at launch. It was ungheard before. To remind dual GPU from previous architecture, GTX590 was ~700$ card, while 580 ~480$. So it used to be that You get dual GPU for less than two cards, now You have to pay for three GPUs to get dual GPU card.
What You witnessed there was blown up prices that made a lot of people angry, but it was marketing stunt that kept nvidia to keep margins & continue inovating as they were putting a lot of money into CUDA, R&D to keep ahead of it's competator (that's one of the main reasons that msot of the fastest supercomputers in the world is filled with nvidia GPUs). Bottom line is that those technological giants are companies created to make profits for investors. The performance wasn't lost there..just product line have been shuffled.
