Skylake vs Broadwell - any new features?

[h4rm0ny]

If you want a mutli GPU setup I'd go with 5930k if you're just looking at a single GPU 5820k.

Skylake - E? a year away? meh.
Skylake now? 16 PCIe lanes? No thank you.

If you install a GPU and an M.2 Drive on Skylake you get 8x performance on both.

Skylake as is is not a Gaming platform, given that you can't use a Multi GPU setup at full capacity, or even use a single GPU and an PCIe SSD.

Wait, what? Okay - this is why people like me need to post threads in places like this. 16 PCIe lanes? That's no good! I'm actually not much of a gamer, but when prices on PCIe SSDs start coming down to sane levels, I will want a couple for work purposes (database and VM stuff). If I hadn't already made up my mind to get the 5820K then that would have done it.

Incidentally, here is my provisional order if anyone is interested.

Btw, I looked for 8GB Quad-Channel DDR4 sticks and couldn't see any (but may have missed them). Am I right in thinking that you wouldn't get quad-channel in a two-stick set but only in a four-stick pack? Because that seemed to be what was available. Quad Channel is worth it over Dual Channel?

Correct, need 4 sticks for quad channel.

If you needed tons of memory bandwidth you'd know about it - there aren't many applications that are really memory bandwidth limited. (I've only ever come across one: the PETSc library for scientific computing.)

If I were buying a quad-channel platform I'd buy the 4 cheapest sticks I could at the capacity I wanted.

Glad I went with i7 6700k. x99 platform while a little cheaper is "not" a gaming one and skylake beats most benchmarks I saw a few weeks back and it's also much cooler 25c idle with H105 and OC's like a boss! If your gaming Skylake is the better platform.

Hahahahaha

No.

OP unless you want a cheap gaming PC i.e i5 + cheap Skylake Mobo then 5820K + X99 much better option.

You get 50% extra CPU cores / threads. More cache. Quad Channel memory and a soldered CPU.

As a budget gaming platform i5 + cheap mobo Skylake is the sweet spot, once you start looking at 6700K money, that money is better spent on X99 imho.

Next year we will get a slot in Broadwell -E upgrade for X99 as well.
