Title: (Cylindrical Mac Pro) Seeking real-world hash rate for scrypt mining
Post by: retiarius@yahoo.com on January 04, 2014, 06:37:05 PM
This would be for using MacOX 10.9, not Windows Bootcamp,
via Asteroid or otherwise.

I've searched the web for actual figures since machines are now out in the field,
but have found no answers, only estimates.   Please specify whether using
D300, D500, or D700 GPUs, though supposedly the latter are only available
in custom configs shipping in February.

Thanx!

I already ordered a Mac Pro with D700 and it ships for February. I don't think anyone really got their hands on one Mac Pro yet, usually it ships first to cities in the US and I'm in NYC. I'll post hash rates as soon as this Mac comes to my desk.

You can expect a very low hash rate compared to the original AMD FirePro W9000 because these cards in the cylinder are underclocked (over-heating I guess) from factory and even if you could (somehow) unlock it for overclocking I WILL NOT even dare to change the clock and memory speed.

If you had the original AMD W9000, overclocked, you could expect a STABLE +1000Kh/s with 2048 stream processors and 6GB memory.
The R9 290 has 2560 stream processors for 860Kh/s stable and the 290X has 2816 streams processors for 940 Kh/s stable, both with 4GB memory each.

So the new Mac Pro has a DUAL, UNDERCLOCKED W9000 so instead of getting +2000Kh/s I'm expecting something under 1,500Kh/s IF THERE IS NOW HEATING ISSUES. If there are heating issues then I could probably get something just over 1000Kh/s.

You are not going to buy this Mac just for mining BUT it can definitively help you pay off some of the initial costs over a 12-month period. I bought it for Graphics and Video work and to show my wife that I'm still the man in the house... :-) And I'll sell my current i7 Intel 16GB memory 27" iMac to help pay for the new cylinder and monitor.

I built a windows mining rig with $3,500 with three R9s, one 7950 and one 7850. The 7850 and 7950 was a mistake, I should have gotten 4 R9s. My hashrate is just under 4,000Kh/s.

I hope this helps,

Alejandro

What's your question ?
D700 GPU is the new firepro gpu just use that on macosx maverick if you are using this

I just received my Mac Pro with dual D500 GPUs, 6-core, 32 GB RAM. Running Asteriod with intensity set to max on both GPUs, I am averaging a little over 1MH/S mining Scrypt.

Thanks for posting real world figures. Any idea what spec the D700 is compared with the D500? Deciding which card to plump for. Obviously not buying the machine mainly for mining, but it will used for mining on its "days off" :)

ah ok, finally found it in "learn more" section of apple store:

----------
Dual AMD FirePro D500 with 3GB GDDR5
Configure your Mac Pro with dual AMD FirePro D500 GPUs for additional graphics memory bandwidth and processing power. Equipped with 3GB of VRAM each on a 384-bit-wide memory bus providing 240GB/s of bandwidth, each FirePro D500 GPU has 1526 stream processors delivering up to 2.2 teraflops of processing power each. The FirePro D500 supports fast double-precision computations, executing at one-quarter the performance of single-precision floating point rather than the 1/16 performance seen in the D300 and most consumer GPUs.

Dual AMD FirePro D700 with 6GB GDDR5
Tackle the most demanding 3D, 4K video, and scientific visualization problems by configuring your Mac Pro with dual AMD FirePro D700 graphics cards. Equipped with 6GB of VRAM each on a 384-bit-wide memory bus providing 264GB/s of bandwidth, each FirePro D700 GPU has 2048 stream processors delivering up to 3.5 teraflops of processing power each, for a total of 7 teraflops. The FirePro D700 supports fast double-precision computations, executing at one-quarter the performance of single-precision floating point rather than the 1/16 performance seen in the D300 and most consumer GPUs.

So no idea what the difference in hash rate would be :) any "wild guesses"???
