Don't buy either R9 280x or HD 7970. ASIC for scrypt is coming.... you would have big problem then...
Doubt it would be soon. Requires so much memory, pretty hard to make even one. Even if they make one, it would be expensive

Erm, the price would be expensive at first but it usually drop pretty fast in few months time..

I have R9 280X and also 7970 OC and 7970 GHZ [ all from Gigabyte ]

R9 280X "OC" 729kH/s
7970OC/GHZ 764kH/s




I have Gigabyte R9 280x "oc" and I cant get anything higher than 610... Would you mind sending your settings to me?

Nice hash you have there... But I hate gigabyte cause its voltage locked...

R9 280x is way cooler... lets just wait for the new chip....

A used 7970 is going for around $200. You will get between 700-800 KHs mining ltc.  A new R9 280X is going cost you $300 or more for the same hash rate.  Cheaper to get the 7970.

Agree to get used 7970 instead.. CHEAPER!!! rocks...

Seems that current R280X are using the full blown HD 7970 GHz chip and the new XTL version will be a lower cost design which gives the same performance out the box, but won't have the OC headroom of the current chip.

You mean the new one is cheaper and worse off?
I haven't heard of anyone with one in hand, so I don't think anybody has an idea if it's better or worse. Gibbo's definition of worse off is probably based on how high he can the GPU, not hash rate.

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.

It's the same card as 7970 Ghz edition (working at 1000 instead of 1050Mhz) just with the new shiny name. Cheesy
Some of the R9-280X will have a new chip (Tahiti XTL). Said to draw less power than the Tahiti XT2 (inside 7970 GHz).

Any idea when the new chip would be in R9-280x?
All I've heard so far indicates that it's a lottery to get the XTL or XT2 if you buy a 280X right now. Some posts say only HIS and MSI so far.

[08:37:20] CHINA: yes, new shipment from AMD will be XTL instead of XT2
[08:40:39] GIBBO: what is the exact difference please?
[08:41:34] CHINA -: well, i do not know know exactly what is the difference
[08:43:12] GIBBO: Please try to find out m8
[08:43:23] CHINA -: ok ok
[10:11:03] CHINA -: Mate, just checked. There is no difference on the specification between XT2 and XTL. The only difference maybe that the overclockability of XT2 is better than XTL.
[10:14:27] GIBBO: why is that m8?
[10:14:30] GIBBO: different power design?
[10:14:53] GIBBO: Will XTL feature the new HD sound found on R260X and R290's ?
[10:15:21] CHINA: no, XTL does not support True Audio
[10:15:55] GIBBO: Why do you think it won't clock as well?
[10:16:35] CHINA: well, i got this from my product development people
[10:17:12] CHINA: maybe related to the screening
[10:17:37] GIBBO: so in short current version is better for OC then
[10:17:48] CHINA: you are correct

Really? Can you let me know how much less power it draws compare to the old chips?

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.
