new build i7 4790k or i7 5820k ? your thoughts.

[Rick Hughes] “Never come across any major enterprise that still issue MAC’s as standard …”

Really? How about IBM! They’re pretty major. They now give their employees a choice of PC or Mac and the Mac’s are flying off the shelves. There is a huge waiting list and people are willing to wait. I hardly see anyone in meetings with a PC laptop anymore. Most developers use Mac’s now. An overwhelming number of tutorials for programming languages and frameworks are given on Macs. And PC sales are dropping while Mac sales are climbing so someone must be buying them and leaving their PC’s behind.

But don’t take my work for it. Hear it from IBM’s CIO himself:

IBM to Purchase Up to 200,000 Macs, With 50-75% of Employees Ultimately Switching From Lenovo

BTW, my first Mac ran circles around my PC with exactly the same specs! I had a Lenovo laptop and got a MacBook Pro with the exact same processor, memory, and everything. In fact, I took 4GB of memory from the Lenovo and put it in my MacBook Pro, that’s how comparable they were in specs. On the Lenovo with Windows 7 with 8GB memory I could load maybe 2 virtual machines before it would bog down and become unresponsive. On my MacBook Pro running OS X Snow Leopard with 8GB of memory I could easily run 4 or more vm’s without any lagging. So my experience was quite different than yours. I moved to the Mac because it’s performance was far superior to a comparably speced PC.

But as you said, everyone’s experience is different.

[Ryan Jones] “I paid just over $1300 but I splurged on a new case and power supply too”

It’s amazing how prices have come down. I paid about $2600 when I built my 6-core 3 years ago but back then the processor alone costs $1000. That’s the price of being an early adopter. That’s why I bought a second-hand Mac Pro. I let someone else pay the amortization. 😉 Good luck with your new PC.

I recommended the 4970k for the low cost of the system for the amount of performance.

The 5820k is a good device, but the 5830k and 5860k are the chips you want to maximize the chipset. The 5820k has half the PCI lanes of the other 2 CPU chips. This means you might be giving up expandability on your system, or the ability to operate GPUs and PCIe SSDs at full speed.

The 58xxk CPU will also give your DDR4 speed on your memory over the 47xxK CPU.

However, I doubt the poster will be maximizing the system configuration to the extent of PCIe SSD, and so the 5820k might be a good price performance.

[Ryan Jones]

The difference in price between the 5820 and the 5830 is around $200 I have not received my order yet so I could send it back in exchange the 5820 for the 5830 but would it be worth the $200 extra ?

Can you explain what you mean by maximizing the system configuration for the pci ssd. ?

Thanks

The PCIe lanes have to do with the motherboard design. The 5820 has 20 lanes directly connected to the CPU, and this is where your GPU gets connected. That means you can only run a single GPU at 16x speed, and one more device at 4x speed.

https://www.intel.com/content/www/us/en/chipsets/performance-chipsets/x99-chipset-diagram.html

The higher end chip has 40 lanes directly connected to the CPU, and so allows you to run two 16x GPUs, and one 8x device like an PCIe SSD or Blackmagic capture device. All without crossing the DMI bridge to the x99 chipset. Not crossing the DMI bridge leaves bandwidth pretty much dedicated there for storage operations.

The 5820 will work just fine if you configuration is a simple single GPU, storage, and no other add-on cards. Apps like Resolve have the ability to use multiple GPUs at the same time. Conceivably you could install 2+ GPUs into an x99 chipset and run at near full speed on them.

You really just need to dig into the specifics on your motherboard you have ordered. Then determine if you really need the extra lanes or not.

I dont think that will benefit me I don’t plan on running another GPU and all my SSD’s are SATA III.

Thank you for the info
