How much has performance really increased?

[evilmeister13]

I was originally looking up overclocking ranges for the 5820k, when i came across an article where two people were arguing that there was no reason to get any of the newer 6 cores, because there was virtually no performance difference since the 3960x. Is this true?

Not true at all. Each iteration of the core series has improved performance by about 5-10%. With that said, the 5820k is also cheaper than a 3960x and is on a modern platform with other benefits -- like PCIe 3.0, which become useful for four-way SLI and future more powerful GPUs.

Performance usually goes up by 5-10% with each new architecture.

If you have a 3960X i don't see a need to upgrade.

It still a great CPU and will remain one for the 3-4 years.

There is very little difference and it wouldn't make sense to upgrade to it from a 3960x. However if you're planning a new build and you need 6 cores, there's no point in getting the 3960x over a 5820k, in fact the 5820k is significantly cheaper, too.

The 5820K is around 15% faster than the 3960X... what makes it an interesting part is that it's $400 rather than the previous six-cores which were upwards of $550.

$1000* (for the 3960x anyway)

I ordered my 5820k last night. However, as linus showed in his recent video, it can only have a max of 3 gpus.

Its not just raw performance. One of the advantages of the new Haswell-E platform versus the older ones is that the X99 chipset is much more feature-rich than the outdated X79 chipset. X79 has been behind on connectivity versus the Z-series chipsets for years already. And while DDR4 is kind of a wash right now versus high-end DDR3, it may end up being a bigger advantage in the future.

yeah, that's why i said upwards of $550, meaning $550 for the entry six-cores or higher keeping in mind the 3930K, 4930K were around $550-600 while the extreme ones were >$1000

should be noted that a motherboard with a PLX chip can double the effective PCIe lanes and allow for 4 way sli at 8x/8x/8x/8x even on a core i7-4770K for example on a Z87 or Z97 motherboard.

Linus should have covered that more in dept so that guys out there won't think they need a 1000$ CPU to run 4 GPU's.

Why do people need to run 4 GPUs?

Well Sandy -> Haswell is ~20% average increase. But as we're talking $500-1000 chips 20% extra performance isn't worth a big cost.
