Thats why I based all my recent rigs on AMD Ryzen processors - unbeatable in price / performance ratio compared to Intel.

If I had to build new rigs with the latest tech I would go ryzen, no question about that.

Opterons are doing pretty well too.

edit: sorry for the OT, i7 thread...

But too bad that no ryzen mobo supports more pci-e slots yet... Or maybe there is but I don't know?

Biostar makes the TB350 BTC, a mining specific motherboard for the AM4 socket. We have 5 rigs running 6 x GPUs and R5 1600 CPUs, all mining of course. With the current price of Monero, Ryzen is a very nice CPU miner.... there are other coins to mine as well if you want to dig around a little deeper.

Thanks for your info, I have checked biostar tb350, but it is just 6 pcie slots, I was thinking to have more than 10 slots motherboard like tb250 btc pro.

Personally from me, the mining on processors has long gone obsolete. If they come up with a new algorithm you can have a couple of weeks of mining

You are right, only new algorithm should worth.

Yep - L3 cache is a dealbreaker in Monero mining. Thats why I based all my recent rigs on AMD Ryzen processors - unbeatable in price / performance ratio compared to Intel.
Dont go below 1600 line. But 1600, 1600X, 1700, 1700X - all will be actually profitable and can pay themselves.
All these CPUs can run at 3.8 GHz safely with voltage 1.23V 24/7 while doing really nice hashrates:
Idle system (Win 10): 44 W
1600X @ 3.8 - 540-550 H/s - 95 W at the wall = ca 41 W of power rise against idle - which is really nice, considering its 95W TDP CPU
1700 @ 3.8 - 630 H/s - same wattage as 1600X

You will probably find some GPUs that can match this performance / watt - but most likely they will consume more.
But Monero is overall more "eco-friendly" than ETH. One of my computers with two 1070 and Ryzen 1600X inside is taking 330W while mining ETH+SIA on GPUs and XMR on CPU. But when I switch also the GPUs to XMR - it takes 235W from the wall. Btw 1070 do around 705-710 H/s.

hope it helps guys - even in i7 thread Cheesy

X5000 series is too old, also some xeons are only rebranded i7's (or other way around). Look at the size of L3 cache, more cache=more threads=more speed.

Thanks for your info, I just get to know that L3 cache benefits in threading. I will read about this to compare against CPU later.

What's Quirky In Life?

You can try using Nicehash (NHEQMINER) to mine equihash with 20 Sol/s per cpu
If you do a combined hashing along with GPU, it will be worth!

X5 performed very bad, just about 200h/s, it is much less than i7 in cryptonight algorithm.

Turns out this little soft knows how to get yourself +10 to +20% in hash rate, without the need to tinker with settings in bios.

Yep, boost on all active cores does the trick.

compare hash rate of i7 vs the hash rate of intel dual xeon e5 ? which of them is more profitable ? or it is much better to buy an intel pentium gxxxx series rig with sinlge 1070 or 1080 8gb gpu.

Dual xeon mb filled with large cache cpu's and hawaii gpu's gives you most cryptonight hash for the buck. Not saying it's the most profitable way to go but if you have cheap electricity, find those parts cheap and want to mine xmr then why not.

Nvidia gpu's don't shine in cryptonight, their hash earns better in compute heavy algos.

I own a i7 machine, and tested with Xeon x5 recently. X5 performed very bad, just about 200h/s, it is much less than i7 in cryptonight algorithm.

- I'd say go with GPU, unless you have access to cheap electricity and xeons, 7970 does 500-512hs...VEGA64 apparently does about 1000hs(mine/stock/claymore/balanced)-1500hs(some people showed screnshot, here: https://bitcointalksearch.org/topic/m.21653108) i have not tried it on 1080ti yet

Xeon@2GHz 44MB cache so 18x2x22= 792 h/s

- what model is that?
and what OS are those hashes are?

*nix, windows. More L3=more threads, it's all about cache.

Any Intel cpu with AES does about 18h/s /Ghz /thread, number of threads is the amount of L3 cache /2. If you are getting less you are doing something (miner, pool, settins) wrong.

Examples (+/-10%):

i3@3GHz 4MB cache so 18x3x2=108 h/s
i5@4GHz 6MB cache so 18x4x3=216 h/s
i7@5GHz 8MB cache so 18x5x4=360 h/s
Xeon@2GHz 44MB cache so 18x2x22= 792 h/s

I remember I check with one of my server but with only 200h/s by using Xeon cpu. I can't remember the model, or maybe let me check it again then post my results here.

your hashrate is good
I'm using MinerGate to mine Monero with i5 2500k, very low hashrate ~90H/s with 3/4 cores
you can see my testing video here https://www.youtube.com/watch?v=fGEA87ogrgw

I think mainly because i5 2500k only 4 threads.

i5-2500 at 3.6Gh, right miner, 3 threads, clean Win gives 145+h/s
i7 should all give 200-270+ depending on frequency.
