Single Threaded CPU's suggestion

[guineadd]

Hello everyone,
in addition to being relatively like a newborn in the world of CPU's, i am also a newly registered member of this forum.
If it does strike too much a trouble, i would appreciate some of your help to create a list of processors.
Recently i was assigned with a project, part of which states that i recommend a list of CPU's for a server which executes mathematical problems that are only executed serially and not parallelly.
Already having wandered the internet for many hours i could not stumble upon anything helpful or specific enough. That made me only assume that i need single core, single threaded, high performance CPU's that are market available.
The price ranging should be near these four different amounts: 100, 500, 1000, 10000 euros.
Thank you in advance for any reply you might provide me with, helpful or not.
Sincerely yours.

You want single threaded performance, you're buying Intel.

You want servers, you'd buying Xeons.

There you go.

Nobody makes single-core CPUs anymore, especially not for the server space. You can ignore the 6 and 8 core CPUs, as well as the dual-socket compatible offerings, though. (So, basically, stick with the Socket 1155 Xeons.)

So, really, the next part of your job is to find the software team and smack them with a shovel until they make the problems executable in parallel.

Intel had a special dualcore Xeon in the old days for just that. But today its not worth to make such products.

What are the options for say solving 4 problems at once? Then you can for example fully use a quad.

Else its just buying the cheapest single socket Xeon with the fastest CPU fitting your budget.
fastest singlethreaded CPU at stock would be:

@dave the nerd - Well, it's just a project which clearly has little impact on reality. I would like to believe that they would not deliberetaly develop only serially solvable problems. Thanks for your suggestion for the Xeon E5630 which suits my budget for 500 euros.
@ShintaiDK i am inclined to agree at looking for fast enough single threaded CPU's still in the market, if there still are available options.

Why not a 3750K,

Close the two cores, OC to 4GHz or more and you done for $229 + Heatsink

You dont OC when you wish to use the data.

FYI, the last single-core Xeon was the 3.0 or 3.2 ghz CPU introduced in 2005. The Celeron G440 was introduced around a year ago and is single-core. The advantage with that is that you literally passively cool that guy...not the fastest though.

More to the OP's question. Intel is the best option here, and you want the best clockspeed on the most efficient platform. That means IB (if possible) and then SB, and then Nehalem, etc. The highest single-core clockspeed is what you want. This probably means a high-speed quad core with a good turbo freq.

The absolute best Xeon for pure clockspeed is E3-1290V2 AFAIK.

Why ?? what will happen ?? with only two cores it will be 1000000% rock stable at 4GHz(even at a higher frequency).

Thats your claim. What you dont see is the silent corruption and suppressed exceptions.

I think what best suits my assignment is a CPU that does not support Hyper-Threading Technology. I managed to find in the Xeon series CPU's for the 500 and 1000 euro budget or at least very close to that.
i) [FONT=&quot]Intel Xeon Processor E5440
ii) [/FONT][FONT=&quot]Intel Xeon Processor E5-4617
# of cores matches the # of threads, with satisfying clock speed.

What i am really incapable of finding is a monster CPU with no hyper-threading technology near the amount of 10000 euros. I believe it is unlikely i find one. Any ideas?
@ ExarKun333 - i checked out your suggestion and is good. More to the point, i agree with the IB choice over SB or nehalem, and i filtered my options from single core (maybe it was a misstatement) to single threaded - equal # of cores with threads.

Why are you searching for a CPU without HT? You can just disable HT if you wish.

I think this CPU is going to be your best bang for the buck.

@ShintaiDK - I asked my professor the same question, and said to just stick to the lack of HT for better financial output with the current budget. Didn't seem to be a problem for lower cost CPU's, but since the allowance for the last cast is tenfold it's highly unlikely that i will be able to find any CPU anywhere near that cost even /w HT; imagine this possibility w/o HT.
Anyways, any ideas for CPU's near the cost of 10k euros?

Nope, that's highly customized and most likely confidential CPUs that you'll see at the 10k price range.

The problem, of course, is that in server space they didn't continue to push single thread efficiency and/or single core absolute speed upward - instead they opted to just add more cores, as most typical server loads are better handled across many slower cores than a few high speed ones.

I seem to recall some truly expensive chips, but there again they were 10-core/20-thread models not 5-6GHz processors.

Most expensive x86 peaks at around 4500$. And they aint for you, 2.4Ghz, 10cores/20threads.

Ahhh....

Your professor hasn't been paying attention to the market.

Those non-hyperthreading units are old tech. They actually are slower than the new stuff at the same clockspeed, even on a single thread.

If you're looking at something faster / more expensive than that, you're basically looking at a RISC/Mainframe rig like a Power7 server cluster or something.

@dave the nerd - Well, that one is for sure, but for a final look's sake i will search for your latest suggestions.
@ShintaiDK - once more it is as you said. Intel did me no good in that final 10k budget area.

Anyways, thank you very much everyone for swift and accurate replies xD
Cheers.
