Hello

I am looking for a performance comparison between qx9650 and Xeon® Processor E5450. In my opinion , qx9650 is faster, but i want a proof. can you help me find.

Thanks.

They should perform rather equally, the Xeon just has the advantage in server environments. What programs are you wanting to use these CPUs with? Games, video editing, ect (desktop stuff), or is this for a server?

i use solid works most of the time. Performance is my first priority. i would like to see performance comparison if you have any. Thank for your reply.

Xeon E5450 should have exactly the same die as QX9650. However, some differences do exist between them.

One of the major difference between them is multiplier. Xeon should feature a locked multiplier, while QX9650's is unlocked. This allow enthusiasts to overclock QX9650 more easily.

On the other side, due to Xeon's higher binning, E5450 should be a lot more stable than QX9650, while possibly churning out less heat. Xeon also features a different socket than QX9650 (LGA 771 for Xeon, LGA 775 for QX9650). Xeon systems also use different RAM than QX9650 (FB-DIMM vs. DDR2/3).

Other than that, both should perform relatively the same at stock setting.

Personal suggestion: If you're looking for performance, and not that much on stability, then I would recommend QX9650. The entire system cost should be lower than Xeons, due to cheaper motherboard and cheaper RAMs (DDR2/3 vs. FB-DIMM). You can get a decent aftermarket air cooler, and overclock QX9650 to 4.0Ghz. Although it probably won't be as stable as those Xeons used in data-centers and servers, but if you can tolerate one crash or two in a year, than QX9650 would be a better choice.

EDIT:

Due to the nature of both processors, there's no direct comparison between them. However, there are benchmarks for them against other processor in their genre.

Hello

Thank you for your time to reply my request. It is informative. This is for my office use and I have no intention to overclock it. system stability is as much important as performance. i do not care of power consumption either. What would you say now between these two.

Thank you.

Then I would still recommend you QX9650. If you're running it at stock, chances are it won't crash. Couple that with a decent air cooling, and a decent case, with a P35 board, then you're all set.

We can also consider from the cost perspective:
Assuming E5450 and QX9650 cost relatively the same: ~1000USD

For Xeon:
Motherboard = 900 USD (300USD*)
FB-DIMM 2GB FB-DIMM DDR2 677 = 100 USD

For QX9650:
Motherboard = 100 USD
2GB DDR2 800 = 50 USD

EDIT: Correction: A LGA771 motherboard cost roughly 300USD, not 900USD. My apologies.

EDIT2: After doing some cost research, both platform should come down roughly the same cost, with Xeon slightly more expensive. Then its really your call. With Xeon, you're guaranteed with absolute stability, while possibly churning out less heat. With QX9650, you can safely overclock it to 3.5~3.6Ghz with stock voltage, with rock solid stability. You might have to restart it once in a while, but it should be very solid.

I would suggest to look seriously at Xeon based boards for Solidworks work, since you can easily buy proven boards with 8 memory slots to support 8GB memory which will help a lot if you work with very large design assemblies.

Some enthusiast-level boards that support the QX CPU line boast that you can put 2GB sticks per slot, so 4 slots (their standard) will give you 8GB, but I don't know how practical or stable these are.

Hello

Thank you guys for all your responses. Based on your responses , it seems like both of them perform about the same. If that is the case , i think i am going to choose xeon because the xeon motherboard supports up to 2 sockets. That mean i can drop in another cpu in the future. Again money is not an object in my case as it is for office use.

Thank you once again. Please also let me know if there is anything i should know regarding my choice.

Thura.
