So AMD just annunced the new line of GPUs. For bitcoin mining they wont be good compared to ASICs but how about litecoin? What can I expect from the 290X? Hashrates higher than the 7990? What do you think and whats your opinion on the card?

R9 290X, aka hawaii

The Litecoin mining will be improved by at least 15%, if using 525Kh/s in previous model, Tahiti XT2 @ 925Mhz core


However, There is one more thing which is enigma, How the GCN 2.0 improve the integer generation?

Additionally, The ScryptASIC.org announced the mini on twitter, Which I am still following when available. The consumption for 5Mh/s is within 200W based on the graph as Scrypt operation is discovered using SHA-2 hash XOR with something else to construct the Scrypt(1024,1,1) so the team uses SHA-2 ASIC to generate some hash, then XOR them to generate the Scrypt(1024,1,1) hash. This is just a concept, there will be more applications if successfully shipped.

It will perform ~15% better on mining overall. ASICS perform ~500% better than GPUs overall. GPUs have long since become irrelevant in the bitcoin mining world. Even if major manufacturers were to add a specific SHA256 function to GPUs, the fact that the only thing ASICS do is SHA256 means that GPUs will never be relevant in the bitcoin mining world again. GPUs are, afterall, basically designed for graphics...

For bitcoin mining. In litecoin mining they are still great and make much more profit.

First of all, it's .org not .com

Second of all, ya it reaks of scam.

They claim to be taking "motherboards parts", converting them with poor photoshopping, adding "stripped down GPUs", adding SHA-256 (REREAD THAT! SHA-256, not scrypt) chips, and then magically getting 50MH/s out of this hackinPC. Bullshit.

and the Hawaii will be even more usefull for scrypt jane (YACoin, YBCoin, ZCCoin, J-Coin, Copperbars, etc.) hashing because it has 4 GB RAM, which means its a smaller hashrate drop with every N factor change than the cards with less memory and CPUs. I will definitely get one.

Yes, however let's pick your example and say that AMD would in fact add hardware accelerated SHA256 to their GPU's. I'd rather buy a $300 videocard hashing at 4 Gh/s than a $275 Japaleno in-hand at 7.5 Gh/s (or similar 30 Mh/$ device), even considering the power usage. I can easily sell videocards to gamers

I`m excited to see how those cards preform. But history have told us that the top card is not always the best buy.(hash/$)
Like the 7950 was a better deal than the 7970. So we just have to wait and see. Smiley

I hope they have better cooling than the 2 wide 7990, because its a joke on how hot this thing runs on AIR. I've got up to 1.5 Ghs on the 7990(I think it could go much higher with better cooling) so maybe 860+ Khs on the R9 290x.

I'm expecting 1 Mh/s scrypt from the 290X. According to techreport the cards have 4 GB Vram, so they suspect it's a 512 bit bus.

GPU is still meaningful as there are new models which will be out like SHA-3. No one currently do something with it. Only SHA-2.

If the ScryptASIC succeeds, then the game will be changed.

I don't think the speed can reach there, But it is possible to reach 750Kh/s without overclocking. I am currently looking into it. If possible I shall get one to find the damn answer.

Guys,
everything is rebrand exept the R9 290X
HD7970 = 280X
HD7850 = 270X
HD7770 = 260X

So, The R9 290 boasts 2,560 stream processors, the current top model, HD7970 has 2048.

Simple math tells us that the 290X should have around 20% better results than a 7970.

So lets say a HD7970 gets to 750Kh/s, a R9 290X should get around 900Kh/s.
Simple math, and then there is overclocking, a HD7970 that runs 750Kh/s is obviously OC'd pretty hard, so I am only just picking easy numbers on that one.

Performance might be significant here for scrypt apps. Can anyone extrapolate approximate performance numbers based on 2816 shaders@1ghz (or 2560@947mhz)?

Do more texture units and ROP units matter for scrypt/sha256?

Don't get caught up in the game and have a nice day!
