It’s time to scrap one or both of my old machines and build a new desktop system.
I’m overwhelmed with CPU/platform benchmarks available on the Internet but I can’t find answers to my questions. So, I hope the futures.io (formerly BMT) is a right place to ask for an advice b/c the main purpose of the prospective PC is trading.
I’ve defined 2 platforms I'm interested in and have to make my choice now:
1. i7-4790K on Z97 with 16 or 32 GB DDR3
2. i7-5930K on X99 with 16 or 32 GB DDR4
All other components will be the same (6 screens, graphic card, SSD, PSU etc)
Software that will be running simultaneously: XTrader Pro with algo lab, IB’s TWS, CQG, IRT, Excel spreadsheets and some other memory and CPU consuming applications.
What could be immediate practical advantages of using i7-5930K/X99/DDR4 system over i7-4790K/Z97/DDR3 besides support of prospective CPU families and potential 128GB RAM compatibility?
Or shall I choose 1150 platform?
Any advise would be highly appreciated.
The biggest difference for me is the higher number of PCI lanes offered by X99. If you plan on running 3-card SLI then X99 may be the better option.
However, the 4790k is no slouch and is right up there and sometimes even faster than the 5930k. Unless you really need the extra PCI lanes, stick with Z97. Much cheaper and more than capable for most applications.
I thought this was probably the most appropriate thread to share my new computer build.
I have 2 AMD desktops. Both run well but really struggle when the market picks up a lot of activity. I am running both Nanex NxCore and IQFeed and my system does a lot of crunching realtime so I wanted something that would easily do the job and replace both my AMD desktops.
So I built a dual Xeon workstation. I bought refurbished EoL Xeons to keep costs low. Still, I get 2.9 GHz (and these go up to 3.8 GHz). 8 physical cores each - 32 hyper threads in all. There are a lot of youtube videos talking about these builds with used Xeons and how they compare to Skylake/Broadwell and Haswell.
Here's the parts list if anyone is interested:
HAF 932 case (I had this from almost 6 years ago and was large enough for the motherboard)
Nice! What sort of performance improvements do you notice? Are you able to utilize all the cores? I'm in a similar predicament and about to build a Xeon setup.
I'm planning to run with a single socket x99/ LGA2011-v3 platform so I will take advantage of the DD4( Also becos I already have an x99 MB). Have you seen all the Xeon samples on Ebay, you can pick up the QS samples dirt cheap- which have the same steppings an OEM chip.

I just completed the build this past weekend. I will give it a couple of weeks and post about any improvements.
I checked eBay and saw the 2670s going for $75. I dont remember what the 2690s where going for but I am guessing they were under $200. I really prefer to buy from a store or Amazon/Newegg where I can be sure that I can return things without any hassle. I guess I never got used to eBay. This is the first time I bought the parts online otherwise I have always bought from Microcenter or Frys. I actually spoke to the people at serversupply.com to find enough confidence to buy from them. I knew I was paying more than some of those prices at eBay but I wanted that 1 yr warranty that came with my purchase.
Congratulations!
Would also love to see some type of performance numbers (CPUid or Passmark benchmarks).
Curious to know how much power are you using idle/full speed.
I built something quite small, efficient (50W idle), quiet and somewhat powerful few months ago (
I really like the Rosewill/Jonsbo U3-B case. It's small, has just one quiet fan, and fits a mATX board (so I can fit a video card and my TV Tuner card). I ordered …
). I love it, and I can run 4 4K monitors with a Quadro K1200 (although I'm just running a couple of monitors now).
I have servers which a close to @Hulk setup (with more RAM, 8 X 1TB SSD, hardware raid, no graphic card, dual 900W PSU, ...) and in idle mode I'm around 140W, so a dual E5-26XX below 50W sound difficult .
I had multiple dual CPU used as my own desktop (the first one was dual Pentium III @ 850Mz, then AMD Opteron, ...) and it's quite fun to build and to use.
But you really have to need it as it's using watts, can be hot and noisy, the mobo are expensive, like the RAM which has to be ECC, etc. But the price/performance ratio is great (using a 2012/2013 Xeon E5 processors), and the older/cheaper E5 have very good single threaded performance which is in most cases more useful than a lot of cores running at a lower frequency.
I think for the E5 2690s the price would be similar to serversupply.com-The cheap prices on Ebay are generally for ES or QS chips. So you are always taking a risk, not just in terms of the chip failing, but it terms of motherboard compatibility.
Please keep us updated on your performance improvements and if you are able to utilize all the cores/most of them. As Sam mentioned it's good your chips have a decent base clock and turbo boost, alot of the Xeons I've been looking at have much lower clock speeds( eg 2GHz base clock, 3GHz turbo), so their single threaded performance is not so good.

Yeah, I will. It feels good reading your and Sam's posts as I was unsure if I did the right thing here. Its a big deal for me to transfer over the system to the new machine because there are so many moving parts. But once it is done, I will post an update.
