Best CPU for running many Java programs for under $100?

[BlueJeansWhiteShirt]

I'm doing a project where I'm needing to run a bunch of Java machines at once and am wanting to build a separate ubuntu rig so its not clogging my normal PC.  Are there any benchmarks out there for this or do y'all have any suggestions?  Don't care about going used as long as there is motherboard availability

You should probably specify platform cost because doesn't mean very much of you can get a cpu for under 100 but it cost 200 for a motherboard.

Sorry, I'm referring to consumer grade CPUs for a desktop machine 

 

Mobos under ~100

In what world is the cpu cost relevant if the cost of the other components aren't taken into account. Do you mean the cost of the entire system?

I already have ddr3/4 ram, power supplies, cases, and drives 

 

I just need a mobo and cpu

Im not familiar with Java and what you would need to run multiple multiples of multiples of it, but you can get 6c 12t xeon x5690 for less than $100 shipped.  You can get the entire Workstation sans an OS and HDD for $220 shipped (z400 workstations on newegg with an x5690)

 

Or get an 8 core FX 8350 for like $70 new or next to nothing used.  But if high core count isn't required, than there are of course other choices if the single threaded core 1 matters more.

Still not enough info.

 

What RAM?  DDR 3 or 4?

Are boards expensive?

Both.  I'm not particularly worried about components beyond the CPU/Board.  I'm leaning toward a DDR3 setup simply because it isn't necessary to have the advantage of DDR4 memory.  I'm pursuing a cost effective machine, not pure performance.

Well, how many virtual machines?

In theory, you can have one virtual machine per core, but for various reasons, it's much better to allocate two real cores for each virtual machine

 

So probably something cheap would be a Ryzen 1600/2600 (6 cores, 12 threads) followed by 1700/ 2700 with 8 cores, 16 threads.

 

If you're not afraid to play around and performance of each virtual machine is less important, you could look at server processors and motherboards.

For example, AMD's old G34 processors had up to 16 cores, and the ones with lower frequency are usually quite cheap. You can also buy motherboards which can host two such processors, so you end up with 32 cores. 

 

For example, you can buy 2 x Opteron 6168 ( 12 core 1.9 ghz) for around 20-25 UK pounds, or around 30$ ... here's some examples : LINK 1 , LINK 2

Opteron 6272 16 core, 2.1 Ghz  costs around 35-50$ each : LINK 1 , LINK 2

 

You have to search for various models because some were produced in higher volume or for some reason they're much easier available.

For example, 6274 (16core, 2.2ghz) seems to be rare and expensive, but 6276 (16core,2.3ghz) is cheap, 22-40 uk pounds each, or <50$ each.

 

The 16 core chips are 627x , 628x, 637x ... you can see them all here: http://www.cpu-world.com/info/AMD/Opteron-model-number.html

 

Dual Socket G34 boards can be bought for under  around 100$, here's just a couple examples:  LINK 1 ,  LINK 2 

You should only need a power supply with two EPS 8 pin connectors (or an adapter to create second EPS 8 pin connector) and DDR3 registered ram, I think you need at least 4 sticks per cpu but it may work with less.

 

Coolers are not hard to find, around 10-15$ each  : LINK

 

So yeah, lots of cores but SLOW cores... so again, if you need lots of VMs running at same time, this would work, power hungry, slow, but you have 32 cores for ~ 200$.

 

v the ones in the video are 6174 (12 core, 2.2 ghz), 10-20 uk pounds on ebay LINK

Yes, but I was pointing towards the workstation setup which contains everything you don't need so likely not an avenue for you to take.  @mariushm has a great suggestion as well.

 

Also don't forget to check out Aliexpress, I have yet to have an issue buying something from there.

[mariushm]

Ah ... here's a nice deal I found :  SuperMicro H8QGi-F Motherboard, Socket G34, with 4 x Opteron 6128 & I/O shield : LINK

 

So 199$ for quad g34 and 4 x 8 core processors, just add 4 heatsinks and tons of ram ... and you need a power supply or two power supplies, because you have a 24 pin atx and 3 EPS 8 pin connectors.

If that's not enough, I think the board supports even 16 core processors, so you could have 64 cores... but may have to look which 16 core cpus are supported (may be something related to TDP per cpu etc etc)

Perhaps you can buy server time?
