Xeon vs. Regular, with questions on Dual CPU.

Hey guys.

I have a question.

I was looking at Xeon CPU's, and option of Dual CPU. I came up with a few questions. (looking at building a pc for CAD work)

For the purpose of learning something here.

5820K vs. Xeon E5 2620 V3 vs 5930K

To start with, i want to look at 5820k vs E5 2620.

http://ark.intel.com/products/82932/Intel-Core-i7-5820K-Processor-15M-Cache-up-to-3_60-GHz

http://ark.intel.com/products/83352/Intel-Xeon-Processor-E5-2620-v3-15M-Cache-2_40-GHz

Both have a 15mb cache.
The 5820k only has 28pcie lanes, while the 2620 has 40.
The core and thread count are the same, while the clocks differ of course.

Throwing the 5930K into that mix its more or less the same picture, apart from both CPU's (5930k and 2620) having 40pcie lanes, and different clocks.

Compare of all 3 http://ark.intel.com/compare/82931,82932,83352

The 5820K is about 15bucks cheaper than 2620, with the 5930K being 170 more than the 2620.

Between the 2620 and 5930K i see price, and clocks as the main difference, i KNOW there are more.

But in my case, looking to build a non OC CAD drawing pc, why not go for the Xeon over the 5820K, mainly due to tiny price difference, and more lanes for more quadro cards with time.

What is lost apart from Clock speed by going Xeon?

Now a question that i just need an answer to, Dual CPUs.

Using 2x 2620 vs 5930K, how would gaming perforamnce be?

Isn't CAD GPU hardware accelerated?

Outside of the clocspeed differences and cache you mentioned, the only thing I can think of as a difference is the unlocked multiplier.

I would imagine 2 2620's would beat out a single 5930K at stock speeds on heavily threaded applications. Otherwise, it wouldn't.

Okay, the CAD work is Solidworks, not that it matters much, but the Xeon would be better choice for office work over the 5820K?

2x 2620@2400MHz = 1x [email protected] in multithreading environment. I already tested that on couple of servers.
5820K = 5930K.
There is also maybe better option for you - single Xeon 2630 = 8 cores but cost not much more than 5930K ( at least it used to cost not much more ).

Price/performance 5820K beats all.

The price diff for the 2630 is more than a little, right now anyways.

Im not looking to do anything about my own setup, its just come up as questions during some research.

But this will be a non overclcoking system.

But strange that 1x 5820K overclcoked (a lot) is same as 2620 in multithread enviroments, as i would think the 2620 would have double threads and cores to work off over the 5820K. But 5820 at 4,8 need more than simple air cooling too.
