Multicore processor question

Am i right to say processing speed is only useful when downloading programs( which i can do one by one with a slower processor, im not in a rush) but once downloaded a bigger cache is better for running mutiple applications???

Duo Core 3.5Ghz Processor 4MB cache or

Quad Core 2.66GHz Processor 12MB cache

Im more interested in running 8 monitors with 16 esignal charts, 20 tradestation charts, forex broker front end, futures broker front end, email and play music at the same time which is better? Im not too concerened that about dwnloading in 2 secs but the ability to run these same time with no problems

Would anyone disagree with the following, with the exception of Tums and his situation? It's from TradingComputers.com:


Dual core or Quad core?
Trading software will not use more than 2 CPU cores; so a quad core will not run your charts faster. It is better to have two fast cores rather than four slower cores in most cases. Buying an F-19 (3.41GHz) dual core saves you more than $200 over an F-11 with a quad core (3GHz) and the faster CPU speeds will do a much better job of keeping up with high volume days.

When test sites compare performance on various apps... at a given price point, the quads and duals trade back and forth as to which is faster on which app.... and the differences are usually small.

Bottom Line... just as Tums said, "it really makes no/little difference"..

Well that part is wrong already. Depends on which software and what you are doing.

For my type of daytrading, pretty much any computer is fine. I'm mostly concerned with just staying connected.

But, please expand on that.

Depending on what charting software you use. Chances are, more and more software will be multi-core capable.

The software I use is MultiCharts. It can distribute my charts over multiple cores.
(but each chart is still confined to one CPU. The advantage only prevails if you have more than one chart.)

Furthermore, multicore can speed up backtest and optimization by many folds.

Here's a screen shot of my test run...

p.s. during trading days... my CPU peaks at less than 30%. Average reading is between 7% to 15%.
Moral of the story... unless you have a special need... there is no need to get the most powerful CPU.

No
Yes
Quad

Your download is typically limited by the slowest of the datarate at each end.

To do what you are describing a Quad core with larger L2 cache is definitely best.

You've asked about the processor. Are you going to build a complete new system, or just replace a cpu? Or are you going to buy a new system?
 
NinjaTrader 7 will support multi core processors.

Unfortunately, we do not have specific recommended hardware settings to maximize the performance of NinjaTrader.

The general rule applies; the faster the machine, the smoother NinjaTrader will run.

i was under the impression that clock speed is king, so an e8400 at 3ghz (which can be easily oc'ed to >4ghz) would perform better than a q6600 at 2.5ghz. as of right now, the best use for quad cores is encoding a vid while watching a blu-ray disc while gaming on another monitor while...etc. true or no?
