I want 60 7970s for around $225 each. If I could find those, I would be a happy camper  Grin

Looks cheaper to buy 280x cards in bulk than 7850s, ppft...

Watching this card is a waste of time unless someone can show it beats an ATI 7950: 160€, 700 Kh/s, 150W



Where can you get a 7950 for 160 euros? That's like $220 bucks, cheapest I've seen is $250.

R290 schuld be the best card for mining LTC/scrypt.


Maybe not, the price is too high but the hash rate is only 100 more...

nobody got real number? hash @ watt?

Read the whole thread man, I posted real numbers with a link to an overclock.net thread with screenshots.

Yeah man.. read 14 pages :-P

From what ive read the card is too new and cannot scrypt mine very well yet. Luckily its power usage seems to be its best feature.

I am waiting for the price to drop.

i read the whole thread, and your post, was the only number around. everybody else was just writing "i read" "i think" "it must be"...

so i am looking for more answers that are backed like yours. unfortunateley yours where very "testing" and I cannot figure what numbers acually run stable through the night at what hast @ watt

if you got stable values, could you please post yours in the wiki?  https://litecoin.info/Mining_hardware_comparison

At $400 a piece it's rather cheap (R9 290 non x).
It does 884kh/s confirmed and I'm sure it can do more, drawing less than 300w.

more efficient in Hash/Watt? I never found any numbers that suggest its more efficient... got any reference?

Both. You need look at the manufacturers figures for both watts and number of SPUs to see it's more efficient.

I have no idea why they didn't just call the new 7990 the R9 299X Grin


Manufacturer figure isn't accurate usually...

unless they have another more powerful GPU in reserve for later. Grin

If your card is working great can you please post the output of MemtestCL. it's kind of like a memory test for GPU

https://simtk.org/project/xml/downloads.xml?group_id=385

Both my Sapphire R9 290X with Elpida Memory chips throw lots of errors

The errors are in     Random blocks Test
Random blocks: 985 errors (0 ms)
Code:
Test iteration 6 on 128 MiB of memory on device 0 (Hawaii): 0 errors so far
        Moving Inversions (ones and zeros): 0 errors (0 ms)
        Moving Inversions (random): 0 errors (16 ms)
        Memtest86 Walking 8-bit: 0 errors (31 ms)
        True Walking zeros (8-bit): 0 errors (16 ms)
        True Walking ones (8-bit): 0 errors (15 ms)
        Memtest86 Walking zeros (32-bit): 0 errors (78 ms)
        Memtest86 Walking ones (32-bit): 0 errors (63 ms)
        Random blocks: 985 errors (0 ms)
        Memtest86 Modulo-20: 0 errors (171 ms)
        Logic (one iteration): 0 errors (0 ms)
        Logic (4 iterations): 0 errors (0 ms)
        Logic (local memory, one iteration): 0 errors (16 ms)
        Logic (local memory, 4 iterations): 0 errors (0 ms)

You will always get errors because the original memtestcl is broken... you should use the fixed one from svn.

aahh okay, thanks a lot. No wonder memtest did not show any errors on my 6970 .

The most power efficient card is the new 7990 (4096 SPUs) with 2x 8pin power. (effectivly 2x7970s with the power of a single 7970!)

The new 7990 has the same name, you can only really tell it apart from the old one by the number of PCI-E Power connectors and that it's 2x wide instead of 3x wide. The old one has 3x 8-pin power, the new one has 2x 8-pin power.

Yes it's more efficient than a 7950 by a long way, heck even 2x 7850s are more power efficient than a 7950.  Wink

Hi scyth,

would you mind sharing detailed information about your system? Board/CPU, etc.?

Low end single core CPU in a mobo with a lot of slots. Mining components not a high end desktop.
