Any news on launch price?

650€ for R9-290X and 520€ for R9-290. All other cards are rebrand with new price and little higher default clocks.

that's even more expansive then a 7990. Need to know which is more energy efficiency Grin

R9-290 sounds like a good idea...

Euro prices translate 1:1 to USD bro, so expect a $520 price at launch. Maybe lower after a month or so.

I think 7990 will be better in terms of speed , they work 1400khash+ dont they? For 650€ wich is supposed to be the cost of 290x you can get 3x 7950 and get 1800khash+ out of it. I doubt 290x will be able to top that.

The 280x might be best/most optimal mining card in terms of €/khash if they come out at 200€ and have the same speed as 7970.

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.

Your math is wrong. All things being equal (they won't be) 750Kh/s would extrapolate to 1031Kh/s for the 290X (37.5% more shaders) and 937Kh/s for the 290 (25% more shaders.)

Last time i've seen the branding there is no 290 non X, so I don't know what you are talking about

There is, I see some review it says that Radeon R9 290 is coming too, being that Radeon R9 290X even more powerful then R9 290.

Are you sure that the following is just rebranding?
HD7970 = 280X
HD7850 = 270X
HD7770 = 260X

Last I heard they are going to improve the performance instead of just rebranding.

Thanks

Well, i've seen reviews but that is just upping the core 50 Mhz and you get 1 FPS more...
And the 270X has 1280 cores, so the hd7850 core has been improved but not by much. (I think a hd7870 has 1280 btw).

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?

Anybody manage to get this GPU up and tested? I would like to know the hashrate, power consumption and can it be undervolted?

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.

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.

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...

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 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 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.
