Radeon R9 280X - new Mantle API - higher performance ?

[tytanick]

Hello guys,
As you know, in few days, there will be New Radeons R9 270X, 280X, 290X in stores.

Interesting fact is a new API "Mantle" (ofcourse there is also DX 11.2 and OpenGL 4.3)

I think that Using Mantle API will give us big improvment in hashing scrypt alghorytm.

Tell me what do you think about it ?

The 290 and 290X will not be released until later this month.
The 270 and 280 models later this week will be rebranded existing chips.
I don't know if Mantle will improve hashing power but I guess someone first needs to write a mining program that uses the Mantle API.

I might be wrong but Mandle seems a replacement for direct3d/opengl and not opencl(/cuda) as one usually need for GPGPU stuff like coin hashing. If so it would be like using 3d gfx api for mining. So I doubt Mantle will change much.

if you're interested, going by THW, its not as good as you think

Anybody know the energy efficiency for R9 280x compare to HD 7970?

Someone needs to go buy one and do some testing. Tom's hardware knows next to nothing about mining.

as same as 7970,lol

Someone who pre-ordered please update the status of the gpu. I wanna know the energy efficiency vs HD 7970

The scrypt fpga coming out are 4x more efficient than 7950. I wonder what these will be.

Scrypt FPGA are a lot more expensive too?

Not sure no pricing released as yet i think.

Base on speculation, its 1.5x more costly then GPU.

that would still be a good deal then if it is 4x more efficient. The new gen of cards won't come anywhere near that efficiency i'm sure. In term of cost of production surely scrypt coins are totally undervalued right now in terms of power needed to create them anyway. I don't mean bitcoin since that is kind of a league of it's own but new 256coins vs new scrypt if the same total coins, block size , rate etc all the same. The scrpyt coins should cost more?

Well i have free power so... depends i guess.

that must be quite a rare position, i don't know anyone that gets free power. Must be a nice position all the same.

People have to remember that AMD made these GPU cards primarily for gaming and HD content, not mining. If they did make one on mining, I bet they can make GPU cards just as efficient as the rumored fpga scrypt miners. Gaming/HD market > Mining market in overall profits....Gamers buy more games and miners just mine, which only the electricity company gains profit.

Hope your not stealing it....Are you getting solar power? Or you at a college dorm that includes utilities? Or at a company using mining as a way to test hardware?

What is wrong with stealing power if you can? 

It's a felony and imprisonment plus fines....
