Is I5 9400f processor is sufficient for deep learning, performing models,Monte Carlo simulation and other heavy works on Matlab

72 views (last 30 days)
I want to purchase a processor for Matlab working. I have initially selected i5 9400f processor . I wanted to know that is it sufficient for my PhD work in CIVIL ENGINEERING (including future work) or shall I go for i7 8th gen processor. Or anybody who can suggest me an ideal processor for the same.

All MC methods are in general extremely CPU consuming. So, soon or later you always reach limits of your computer. From this point of view I suggest most powerful CPU you can buy by your budget + additional RAM + fast SSD disk. In some cases GPU capabilities (cuda) are very useful.
Minimum config:
- CPU with 8 physical cores
- 32GB RAM
- SSD system system disk 256GB or more
- HDD data disk 1TB or more (7200rpm)
- NVIDIA graphics card - gpu-cuda computing
- Linux OS

Any processor that will support MATLAB is "sufficient" to use Monte Carlo methods. But will it leave you desperately wishing you had bought something with more capability? Well, yes, an i5 processor might be exactly that, something where you wish you had chosen better.
I would suggest you look at benchmarks like those provided by Geekbench. There you can see how similar systems perform, before you invest the money.
My suggestion is to take the advice of Michal here. Look for a processor with multiple physical cores. Hyperthreaded cores do not count, as they do not give you any real benefit. As much memory as you can afford, and as many cores. An SSD drive is a huge boost.
One final thing that is hugely important though:
Computers that will have heavy compute loads MUST have a good fan, as it is easy to otherwise overheat that processor. And too much heat will cause your computer to fail, so it will automatically slow down the clock speed, by dramatic amounts. So beware using a laptop system for long term heavy computing, even the very best processor can easily get heatbound, running slowly because you did not provide the necessary cooling capacity.

Dear jhon, the link attached is AMD listing brother. Most of them have not even released in India . Can you please help me with the same but in Intel processors considering budget issue also.(but if you think budget as hurdle then u can ignore it at some extent)

Often the question arises about whether to get fewer but faster cores, or more but slower cores.
The answer depends a lot on your computing mix.
Having more but slower cores only wins out if the majority of your work can be done in parallel and your problem size is such that you are still getting notable incremental improvements with adding cores.
There are some kinds of problems where adding more cores is almost always better: problems where the cost of transferring data into and out of the cores is small compared to the work done on the cores.
However most of the time the cost of starting the extra processes and transferring data to them and transferring back, exceeds the cost of doing everything in one process with automatic parallel processing. It needs special attention to the programming to take advantage of the parallel cores in a way that makes them a net benefit.
A lot of the time, you are not running that carefully programmed code, and at the other times, faster CPUs almost always win.
There is the old saying, "Never underestimate the bandwidth of a tractor-trailer hauling a load of magnetic tapes." There are some tasks that 1000 "slow" processors can chew through much more effectively than a couple of overclocked nitrogen cooled CPUs. But most of the time you are not doing those specialized tasks, and 8 hot-rods can be pretty sweet the rest of the time.

And as per my knowledge AMD processors sometimes needs different programming style than that of Intel . Is it true ? And my seniors and in my surrounding no one uses AMD SO, Will I find difficulties using AMD ?
