Intel i7 4790k vs 4930k performance difference.

#1 Posted by mattamomo (924 posts) -

I'm thinking of making the upgrade to improve on my workstation.

I assume the extra 4 threads would increase performance significantly in 3D applications and rendering.

And would provide a good few years future proofing for gaming.

Has anyone got one that can comment?

I've not got one but unless you're using really really heavily cored (multithreaded) workloads I wouldn't bother.

@klunt_bumskrint: So far I haven't been, but I am planning on investing in Maya and am looking to start learning a bit more and progressing in 3D modelling and design. I don't know if 8 threads will be sufficient.

They will, if not go Xeon.

I use 3ds Max and ZBrush all the time on a 3570k and it's doing great, so the 8 threads will be more than sufficient. Keep in mind that it will only help the rendering, and not the application's performance while working.. The latter falls on the GPU.

http://cpuboss.com/cpus/Intel-Core-i7-4930K-vs-Intel-4790K the 90K kills it with single core performance, if you're looking into apps that use only 1 core then go for it, if not then the 30K totally destroys it in every other term.

Why don't you just wait for the 5930k? It comes out in a few weeks.

Or go for the lower 5820? Six cores, but fewer PCIe lanes-

This too. In fact, the 5820k is the best choice. 28 PCI-e 3.0 lanes is still enough to power two high-end GPUs without a lane bottleneck, possible three AMD gpus too. (Nvidia doesn't like x4 PCI-e ports)

@ShadowDeathX:

Any release date for a 5820k?

#11 Edited by Horgen (111188 posts) -

Assumed it is the same as for 5930 and 5960. October I think.

@ShadowDeathX: I think the PCIe X4 isn't enough to keep the third AMD GPU well fed sort of speak. It allows it, but you get better performance if it is X8.

I would never get more than 2 way SLI so is the 5820k still good for that?

A Gen3 PCI-e x4 is more then enough bandwidth for another GPU (prob. not count a Titan Z or 295X2). I just know Nvidia has a restriction on using x4 ports.

But those lanes are better used for SSD, Wifi, or a sound card imo.

More than enough. The new chips and their motherboards come out by the end of this week (unsure if paper or official release) but they should easily available for purchase the first half of September.

@ShadowDeathX:

Great to hear, will wait till then.

Cheers
