An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

[pooler]

does 8.04 khash/s(like 2khash/s per thread) look right for an opeteron 2374HE @ 2.2ghz? just hopeing i didnt do something wrong in the compile

Being based on the K10 microarchitecture (specs), that processor should be able to do about 16 kh/s in 64-bit mode.
If you're in 32-bit mode, I'd say 8 kh/s is fine.

Thanks, I fixed that. Now to get a bunch more server up.... I hope it becomes self sustaining

Just for the fun of it :

Intel U2500 processors ( does not even support 64 bits ! ) doing 0.93 on each thread so 1.85-1.86 khash/s in total

LOL. Running on a Dell D420 laptop with custom cooling solution. Max temps are about 70 degrees. Not bad considering on Skype before the custom mod it was 78 !

Is there a hardware wiki where we can put this information for LTC ?

Any better miner than this one of Intel CPUs ?

Thanks !

Most of the information seems outdated, so new benchmarks are very welcome.
Please, always specify the miner version.

Miner is your latest Intel optimized miner 2.1.4

I always told them that Intel would own those silly Phenoms.
 
A 2600K at 4.7 GHz does ~48 khash/s. No AMD can come close to that.

Thanks again pooler for bringing equality to CPU mining !

To summarize :

Intel U2500 = 1.86 khash/s ( Linux 32 )
Intel 2600K = 48 khash/s ( W7 64 )
Intel E8500 = 9 khash/s ( XP 32 )
Intel P8400 = 10.3 khash/s ( not bad ! W7 64 )

Anyone get any better results

U guys should love whats coming up

Holy shit, I'm regretting that I didn't buy an fx. (Kidding, but still, daaaaamn)

Will Phenoms see any improvement? Right now my 955BE at 3.9GHz is getting 7 khash/s per thread.

depends if it has xop and avx

It doesn't
Still cool though!

As was heralded by aaa801, here is

Version 2.1.5

• New optimizations for Sandy Bridge (recent Intel processors) and Bulldozer (AMD FX series). The speedup should range from 25% for Intel to 45% for AMD, but only in 64-bit mode.
• Building on Windows should now be possible without having to perform satanic rituals.
• Building on Solaris using gcc should now work out of the box. (Thanks to pontius!)

The source code is, as always, available at GitHub. Binaries will be available soon available here.

Many thanks go to aaa801, shakti, and xurious for letting me use their CPUs during the development process!

HOLY SHIT Dude! You got 45% out of BD?! NICE! Is there any way to use FMAC? or is that strictly just fpu stuff...
When will 2.1.5 binaries be avail for win?

yeah, my sandy-i7-2600k at 4.6_ghz/8_threads/w7_64 does ~59 khash/s   version 2.1.5

thx for the excellent work

Edit:
sandy-i7-2600k at 4.6_ghz/6_threads/w7_64 does ~42 khash/s / version 2.1.4 / 99.5 w
sandy-i7-2600k at 4.6_ghz/6_threads/w7_64 does ~53 khash/s / version 2.1.5 / 96.5 w

more load with less power  

[tgmarks]

my laptops pulling 35 khash/s.  this is sweet

o yes, my cpu runs at 4ghz :3

Not sure what the problem is exactly, this happened a few times

I've seen quite a few boooos today as well but I don't know that that has anything to do with the new miner.

As a data point, I get 38.5kh/s on 3 cores of a 4.3ghz 2500k. So, about 13kh/s per core (verified by running 4 cores/4 threads). Previously, I was getting about 10.5kh/s per core.

There seems to be something wrong with the new miner:

Round Shares
Your Valid: 4630
Your Stale: 500, 10.8%

Using 2.1.4 I got 0.5% stale

This is happening on both the Windows and the Unix builds

edit: seems okay now, wondering if the problem is actually pool-x.eu
Earlier today I was getting a lot of stales but so was the rest of the pool, maybe it has nothing to do with the miner

At the moment I'm getting 60 kh/s on my 2700k @ 4.5Ghz.  A 25% increase in hash rate is impressive.

[TravisE]

Awesome. Looks like I've gone from about 25–27 kh/s overall on my i5 2500K to around 30–31. Pretty noticeable difference.
