I've never come across one like that.  All I see every day is people having difficulties for a variety of reasons with Nvidia cards.  And when I go to buy a card, I find more power for the dollar in AMD cards.  And this nonsense with them being optimized for Cuda and rubbish at OpenCL on purpose, that would be like buying a Dell computer which runs Windows fast but Linux slowly, and denying you half of your own RAM.

well you don't have to come across it for it to exist. Those models cards do exist. So now you know that if you're ever in the market to buy one, there's 2 models. It was just an example to show you that AMD isn't this infallible company that doesn't do the things you think nvidia shouldn't be doing. They do the same things, you just aren't aware or remain willfully ignorant due to fanboyism. 

and of course nvidia cards are optimized for CUDA. It's THEIR product. Nvidia made CUDA, and it only runs on Nvidia cards. 

you wouldn't find more power for the dollar running a project that has highly optimized CUDA apps. Like SETI was (AMD cards were NOT competitive there, used more power and processed more slowly), or GPUGRID (which doesn't even have AMD apps at the moment). AMD only has more perceived value to you because you don't run the projects where optimized CUDA apps exist. That makes your point of view very subjective. 
 

then you have outliers like Milkyway. Which in "general" give an edge to AMD due to the reliance on double precision performance. But even there, the best AMD card (Radeon VII) gets solidly trounced by the best Nvidia card (Titan V). Granted the Titan V is an expensive card, but it's older, and still more power efficient. AMD has always struggled to beat Nvidia at the highest levels.

You also forgot there is the 5GB GTX 1060 for the Chinese market only.  It just is product stack differentiation for different markets in play.  Nothing more other than to maximize returns.

Yup I figured there's a very rare possibility that anyone here would have one lol. You pretty much have to buy them on aliexpress to get them outside of China. 

there also exists a GTX 1060 with 6GB of GDDR5X. But again, a rare card that probably no one will ever see.

I have had heat pump for a long time and would get rig of them in a heartbeat if Ihad the chance!! They are noisy in the wintertime when they go into the defrost cycyle and although they do work in the summer  time they won't guarantee to cool more than 20F below the outside temp. So when it hits 100F+ outside the thing struggles to keep the house cool, you'd think you could just get a bigger one but NOOO because then it won't run long  enough on the normaly hot days to justify the cost. In the winter the air that comes out is NOT hot air it's WARM air, meaning if it blows on you it feels cool. If it get's below 40F outside the efficiency goes thru the floor and gets worse as the temps go down. One good thing people can do is replace the backup wires with a propane or natural gas heater box so the electicity costs go way down when it can't keep up because it's too cold or you asked for it to be more than 2 degrees warmer than it  currently is. Yes you have to get up and change it  so it doesn't get warmer than 2 degrees at a time or the wires come on. Also if you don't get the right kind of  thermostat to only ask for 2 degrees at a time then you can't use the temp setback feature at night. YES a heatpump is cheaper than two seperate systems. Fortunately for me I do have some propane fired gas logs I use in the Winter to warm up the house on the chilly mornings, they aren't great but they do warm up the house especially after I had a fan installed in them.

In my computer room I had mini-splits installed and that is also a heatpump but was much cheaper  than a standard a/c system because it required no duct work, I had one room to do so it was really easy. If I had had to do more rooms I would have gone with a regular a/c system with duct work. It will never run in the heatpump mode except for testing by the guy doing the servicing while I live here.

I've heard so many wonderful stories about them though.  How they cost so little to run and people don't understand the Brits still using gas to heat their homes.  In fact our country has banned the installation of gas heating after 2025 in newly built homes.  There's a load of new houses built 5 miles from me, and every one has a heat pump on them.  Nobody I've asked has a problem with them.  Like everything else, you can get good and bad ones.... But since I'm just going to get a £420 model, it's no great loss if it sux.  And since in Scotland there's no extremes of temperature, and I'm not that fussy, I just want a small amount of cooling or heating and completely automated, without the hassle of water pumped central heating which is constantly going wrong.  Slightest little airlock and it stops working, really annoying.  Where I used to work they had them insatalled in every office, they worked great.  Ceiling mounted things, took up no space, hardly made a noise.  You simply selected your preferred temperature on a controller on the wall and it heated or cooled as required.

Well I do usually compare several sales when buying them, so hopefully I'd notice some had inferior memory.

No idea where you get this fanboy nonsense from.  I buy what I hear the best things about.  I avoid French cars because countless friends have had them break down.  I avoid Nvidea because I hear ten bad stories about them to one bad about AMD.

Sounds rather like Apple.  Make their own stuff and screw everyone else.  Forget compatibility, you must use our stuff!

I buy the cards with the most flops per £.  That always ends up being AMD, by a country mile.

I buy cards valued at about £50.  New cards from any company are way too expensive for the performance increase they give.  Same goes for cars.

I guess I could buy one from China then :-)  But the last thing I bought from China incurred me customs fees of 2/3rds of the price of the product.  I'm currently getting very annoyed with Royal Mail, customs and excise, Ebay, and the Chinese seller.  If all 4 refund me, I'm in profit :-)

There are two on Ebay right now (from China).

I am with you mikey.  I once had a heat pump in Florida.  On reverse cycle in winter it could not heat the house without engaging the heat strips.  Then one night at around 28 degrees something went wrong.  i went outside and the outside unit was a solid block of ice.  This unit was only 10 month old.  Since moving into my current house I have never looked back.

Knock on wood, I put a

Knock on wood, I put a mini-slit heat pump in last Oct. and it worked fine thru the winter down to 25f. My power usage for heat is ~1/3 of the restance heat I previously had to use. It is made in China and I got a very generous rebate from my power company. After the rebate it cost me $200. plus $1500 installation. Only 1 more year and it will be more than paid for. I like the lower power bills, the green aspects of it and the greater comfort it gives me. Generally in business capital investments that break even at 5 yrs are concidered to be profitable. 

Metinks 3rd generation heat pumps are a different animal than earlier designs.
