Title: R9 280X or HD 7970 Post by: Aalesund on October 18, 2013, 05:58:05 PM Hello,
I want to buy a new video card, but don't know which one to choose. I will use my pc 50% for gaming and 50% for mining. For gaming both are very good, but which is better for mining? AMD Radeon R9 280X or AMD Radeon HD 7970 Both cards have the same stats, but some say that R9 280X is 20% faster, that true? Which one to buy? Title: Re: R9 280X or HD 7970 Post by: middlemarkal on October 19, 2013, 01:48:54 AM From what I read on the web a 7970 GHZ edition est 5% faster.
purchase a 7970 with the game package. ;D Title: Re: R9 280X or HD 7970 Post by: hulk on October 19, 2013, 02:46:41 AM Hello, I want to buy a new video card, but don't know which one to choose.

Title: Re: R9 280X or HD 7970 Post by: RandomQ on October 20, 2013, 08:19:05 PM I think the R9 280X is going to dethrone the 7950 as the go too Altcoin card. I hope with tweaking it will get 800Khs. I've been able to get 750khs per GPU on a 7990, but the cooling was holding the card from going above 1500. I got one on order and will see how things go
Title: Re: R9 280X or HD 7970 Post by: imrer on October 20, 2013, 09:00:00 PM I would choose AMD. I had one older card and I can't say a bad word about it.

Title: Re: R9 280X or HD 7970 Post by: Kimowa on November 01, 2013, 12:02:48 PM Guys, everyone should buy the R9 290x instead, it is the best of all. Just wait for some promotion before buying them :)
Title: Re: R9 280X or HD 7970 Post by: Zawamiya on November 01, 2013, 03:51:35 PM I prefer getting 2x 280x, but I will wait for R9 290 before deciding...
Title: Re: R9 280X or HD 7970 Post by: winner999 on November 01, 2013, 08:37:38 PM It's the same card as 7970 Ghz edition (working at 1000 instead of 1050Mhz) just with the new shiny name. :D
Title: Re: R9 280X or HD 7970 Post by: Sythyn on November 02, 2013, 12:45:02 AM HD 7970, way cheaper right now on 2nd hand market...

Title: Re: R9 280X or HD 7970 Post by: Omikifuse on November 03, 2013, 05:48:09 AM Buy R9 280x, its the best for its value...!!!

Said to draw less power than the Tahiti XT2 (inside 7970 GHz).Title: Re: R9 280X or HD 7970 Post by: winner999 on November 03, 2013, 09:13:31 AM Yes, the only way to recognize them form "regular: R9 290X will be to read BIOS with GPU-Z. Now every R9 280X is using Tahiti XT2 GPU. I hope they will have smaller VGPU, something in the range 1,09-1,13V would be nice.

You mean the new one is cheaper and worse off? Going through the convo again, it's possible for the XTL to be a less leaky chip (easier to undervolt, less power, decreased heat, cannot clock as high). I looked at the LTC mining hardware comparison. Fastest hashing 7970 is at 1085/1500 w/ a voltage of 1.1 (undervolted). That same clock speed should be achievable easily with a XTL, as hashrates are not dependent on hitting 1300MHz on air. Last I heard it reduce power consumption, any idea? Nothing new yet.Title: Re: R9 280X or HD 7970 Post by: dogjunior on November 09, 2013, 09:48:58 PM A used 7970 is going for around $200. You will get between 700-800 KHs mining ltc.

Hopefully you at least get one that a miner didn't owned. So far I've had a 85% failure rate on my cards after 2 years of mining.

As i said i dont belive in used cars, they might be used 100% all of time like mining now.

The 2nd hand lifespan used to be longer, But I guess due to the recent mining operation the card that you get might most probably be used for mining and the lifespan is like 40%? Title: Re: R9 280X or HD 7970 Post by: Johanna on November 16, 2013, 03:26:44 AM R9 280 (Not R9 280x) should be the best choice, I was told that if it come with the new chips, the power consumptions would be at lowest...
Title: Re: R9 280X or HD 7970 Post by: whitemage on November 16, 2013, 04:33:35 PM Wait for R9 280 guys, without the x... it should be even better then R9 290 or R9 290x..

No sorry the X editions are better because they have more shader cores unlocked. More shaders cores = efficient mining. The shaders cores are whats used for computing the hash. To use the older card designators a 280 is a Pro and a 280x is an XT.

There is no such thing as a R9 280. Nothing is listed on manufacturer's pages or retailer websites.The rolling update of a new chip is for the R9 280X. The chip and naming progression are as follows: Tahiti XT (7970) -> Tahiti XT2 (7970 GHz, early R9 280X) -> Tahiti XTL (R9 280X) Title: Re: R9 280X or HD 7970 Post by: Junkey on November 22, 2013, 10:25:00 PM I just got a new Sapphire 7970 3GB GHZ verion for $240 two days ago. Which was $60 less then the R9 280x at the same time. Grab the cheaper 7970 on a deal.

Title: Re: R9 280X or HD 7970 Post by: rampalija on November 23, 2013, 06:44:12 PM I think the R9 280X is going to dethrone the 7950 as the go too Altcoin card. I hope with tweaking it will get 800Khs. I've been able to get 750khs per GPU on a 7990, but the cooling was holding the card from going above 1500. I got one on order and will see how things go Why not wait for R9 290x? when is that out? and further more, what is going to be the top of the line? R9 290x seems to be the best right now in-term of power consumptions.. FPGA is better.... coming out soon.. But R280x is way cheaper then FGPA.... used 7950 Title: Re: R9 280X or HD 7970 Post by: alevlaslo on May 04, 2015, 05:51:19 AM Hellow!
I have a laptop HD 8970M graphics card, mining on monero (CryptoNote), it gives 430 hashes or 0.3 dollar per day, while consumption of 100 watts, this is 333 W/h on the dollar profit in a day. It has the highest efficiency among all graphics cards (I am the owner of serendipitously) ;) For comparison with HD 280x, it gives 460 hashes through consumption of 260 watt Title: Re: R9 280X or HD 7970 Post by: Corsa1r on May 08, 2015, 10:21:09 AM Hellow!
