Xeon vs I7 - looking for insight
show user profile  Dr. Jim
Xeon Processor E5-2650 v2 (Eight Core HT, 2.6 GHz Turbo, 20 MB cache
Intel® Core™ i7-4790 Processor (Quad Core HT, 3.60GHz Turbo, 8MB cache
i7 4960X

Thinking in terms of 3D work, video editing..etc. Not gaming.

8 * 2.6 = 20,8
6 * 3.6 = 21,5

i7 wins! also, its overclockable. also, its newer (ivy as opposed to sandy, +8% performance right there). also get the 4930k, it overclocks to exactly the same performance as the 4960x and costs almost half less. Invest the rest in some quality cooling and oatmeal cookies. Winter is coming. Also, stop right there! I'm out of date. 5930k is released tomorrow, get that. it has a 512 bit simd so its theoretical peak performance is double of the 4960x, whenever render engines get around to using that.

Unless you get two Xeons? Isn't that the whole point of Xeons? To be able to stack them?

So that logic then:

My current system is 2X E5645 (hex cores) at 2.4ghz
So does that mean my current system (12*2.4) = 28.8 is faster than any of those options???

Doesnt new architecture and cache and all that other shit come into play?

your money would be better spent on i7s.
Xeons are DataCenter/Server oriented for handling lots and lots of sensitive data. Basically they allow you to use ECC memory so that errors are recognized and fixed as data is processed. (ECC == Error Checking and Correction)
They are also server grade and thus more reliable, but for the same reason you can't overclock them.

Hello there

beautiful ;3

Yes. Technology does come into play but not much. In theory, ivy and sandy have a 256bit simd unit vs the 128bit one of a westmere so should be double performance right there. However, none of the render engines actually make any use of 256+ bit instructions so meh, the actual gain clock to clock is more like 10%.

Now that I know what you're sitting on right now, dont buy anything at all! Would be a downgrade.

Now....with all that said....I can add another Xeon to the sytem:

Proposed system: 2 X E5-2650 v2 (8 core) = 16*2.6= 41.6
Current system: 2 X E5645 (hex cores) at 2.4ghz (12*2.4) = 28.8

In the above case.....the new proposed system WOULD be much faster than my current system.
Also taking into mind the new system would have an SSD for OS/apps...etc.

Rendering aside: Interactivity with the machine while working (in Max, In after Premiere) is important as well. So its not like 'rendering' is all I care about. I also highly value 'all around peppiness of machine'.

Ok, but seriously, E5-2660 v3 was released literally yesterday and that is 10 cores 2.6ghz @ the same price point, just give it a week-month to reach your local retailer, depending on where you live.

for reference, IPC has improved clock to clock like thus so far (looked up the figures from my previous benches, legit!):
westmere->sandy ~13%
sandy->ivy ~5%
ivy->haswell ~8%

so in a better adjusted comparison
2x e5645 = 2.4 * 12 = 28.8
2x e5-2650 v2 = 2.6 * 16 * 1.13 * 1.05 = 49,3584
2x e5-2660 v3 = 2.6 * 20 * 1.13 * 1.05 * 1.08 = 66,63384

bam! thats a nice chip.

EDIT: bah, looks like intel actually pushed the release to september 14
