1800X Build or 7820X Build For $70 More

[TStahler]

I am having a bit of buyer's remorse in that I very recently bought a Ryzen R7 1800X processor and Asus Crosshair VI Extreme Motherboard that I got a good deal on. I also bought 3 year protection olans for each component so if I overclock and kill the components prematurely they will be replaced at no charge. No matter which system I go with, I will be upgrading in a little under 3 years at no additional cost to me because of the service plan so it also doesn't matter if one socket is dead or not either. I will upgrade the CPU and Motherboard at that point to restart a new 3 year service plan at that point. I have a 360MM Liquid Freezer 360 to cool the CPU, GPU I already own and is an R9 295X2 and an EVGA 1600W Platinum power supply. I picked up 32GB of HyperX 2666 RAM. This computer will be primarily used in a home based recording studio for recording, mixing, mastering, editing, and rendering. It will also be utilized for Office work as well as possibly light to moderate gaming. If I stick with Ryzen I will overclock to 4GHz. I also have an option to return this CPU and motherboard and get an i7 7820X along with an MSI SLI Plus X299 motherboard and the overall cost after service plan would be an extra $70 overall. Woudl the pwrformance improvement be worth the extra money? I have read that the 7820X is a hot and unstable processor and that it really requires a custom loop to cool it. I also have my reservations about dripping from a top of the line motherboard with Ryzen to what I probably think is a mid-grade x299 MSI SLI Plus motherboard to keep costs down. I also would have to drive an hour each way to return and exchange the items. Is the performance improvement worth the extra cost? Would it be more of a hassle than it is worth? I am coming from an FX 9590 so I am sure both would be an improvement either way. Thank you all in advance for your inpht on these two options. Thanks.

Worth the cost is subjective. The Ryzen 1800x will perform well at all those tasks you listed.

The question is will you make more money if the CPU gets the work done faster? If so, then it is most definitely worth the cost.

Based on the reviews I've read. You should get a decent overclock with the Liquid Freezer on the 7820X. People seem to be hitting the 4.5Ghz to 4.7Ghz with good All in One coolers. You could likely go higher if you cool the VRM and delid the CPU. Even if you just went with a light 4.2Ghz OC. The 7820x would trounce the Ryzen 1800x.

I do worry about the added heat, power consumption, and stability with the Intel build as well as I question the quality of the MSI SLI Plus X299 motherboard. My Corsair 780T only has so many places for fans and has no spots for side intake fans to cool the VRM. So when it comes to overclocking and stability, I am just not sure. Extra perfomance is nice but I will value stability and reliability over speed any day. Any thoughts?

I am using a 7820x cpu for my numerical simulation (24/7) with Cooler Master master liquid pro 120mm in push-pull configuration.
MB: ASUS Prime x299-deluxe, G.Skill Ripjaw V 2400MHz, AMD RX460, Cooler master V750 psu and 4 other fans.

All cores @ 4.2GHz OCCT test with AVX offset -2: temps doesn't go beyond 75C.
However as I'm setting my PC for 24/7 usage, I have settled on 3.6GHz @ {vcore 0.9V and AVX offset 0} with maximum temperature of 56C!
All of these temperatures are reported with motherboard sensing ambient temperature @ 24-27C...

Edit: cooling VRM is actually needed if you are planning to extremely overclock the CPU...

Computer would likely be used approximately 6-10 hours a day.

My Graphics card being an R9 295X2 2ould contribute to heat. My case has two 140mm intake fans in front, one 120mm on bottom for intake, a 120 exhaust in back along the the 120mm one attached to the GPU radiator, and on top the Liquid Freezer Pro has six fans set tobexhaust out the top of the case. Not sure if that will be enough to cool the VRM, CPU, and GPU overall. Does that seem like enough cooling?

You will be very pleased with the 1800X compared to your FX-9590.
You may or may not be able to OC to 4.0, depending on your luck in getting a good chip.

On the swap deal, worth is something only YOU can determine.
a difference of $70 one time seems like a good deal to me.

If budget is important to you, could you get a similar deal on the i7-8700K?
Overclocks will be in the 5.0 area, and I would think that 12 faster threads would compete with 16 slower threads.

Is this the cpu cooler you are going to use?

I think that's pretty enough for 7820x as my 120mm liquid cooler is also capable of keeping the CPU cool with reasonable overclocking...
As I said VRM temp is not an issue if you are not planning to do heavy overclocking and disabling safety mechanisms in bios.
You can watch OC3D video regarding x299 VRM temp on YouTube.

One thing worth mentioning is the performance hit associated with the new Specter and Meltdown security vulnerabilities as I haven't updated my MB bios to avoid this and I don't know how much it could affect my type of workloads.

That is some heavy duty cooling you have. Unless the fans are low static pressure garbage. Which I don't think you'd use based on the premium equipment you have. You should be getting good airflow around the VRM for passive cooling. As long as all air flow is in the right direction and the case isn't in a restricted environment. Such as inside a desk cabinet.

While every motherboard and CPU is different. I don't think you'd have any problems with the VRM at lets say 4.2Ghz. Most likely you could go higher. In a Tweaktown article I read. The reviewer did not think direct VRM cooling would be needed until the 4.6Ghz mark on his sample unit. For your specific motherboard. Kitguru.com reviewed it. They hit 4.6Ghz with a 7900x before temps became unacceptable. Anandtech hit 4.5 and TechPowerup 4.6 on the same CPU and board. They appear to be hitting 4.4 to 4.5 Ghz at stock voltage.

The 295x2 may contribute some heat but most of it should be dumped directly out of your case by the hybrid radiator. The rest of those case fans should be moving out any other hot air rather rapidly.

As power usage and thermals increases exponentially. There is a huge gap in power usage and heat generation between 4.2 Ghz and 4.6 Ghz.

I won't lie that I am also speculative of buying Intel after the Spectre and Meltdown patches since they will likely affect performance especially of workstations. I wonder how the 7820X will compare to the 1800X after these updates. From my understanding Intel based workstation performance has been hit the hardest by the updates.

 

[velocityg4]

I think Intel is just the most publicized. My understanding is AMD is also effected. By GPZ Variant 1 and 2 (spectre) not 3 (meltdown).

I have a 7820x and all the benchmarks I saw it gave a nice spank to the 1800x and the 1900x. I did get mine for a good bundle price after already purchasing an 1800x and motherboard. I took the 1800x back and have no regrets after putting some water cooling on my 7820x CPU. The water cooler was about $100 so no big price addition since I was going that route anyway after doing more research. I don't care about the lanes as 2 M.2 drives and 1 video card is all I need for my build. You can add SSD drives anytime or spindle drives for more storage.

My specs are MSI X299 Raider MB, Intel Core i7-7820x 3.6 Ghz 8/16, ASUS GTX 1080 Strix, Ballistix Sport Gaming 32 Gigs DDR4-2400 1.2v RAM, 500 Gb 960 EVO M.2 Drive and Seagate 2TB 7200 RPM drive, Corsair h100i v2 Water Cooling.

Having an 8 Core Intel Processor feels very good. The Skylake was not what we wanted but it is good enough for now and a great price compared to the 7900x which it beats out when comparing apples to apples and price. I paid around $210 for the MB and $425 for the CPU so I can't complain about anything. Ryzen = non elite. Intel = elite. That is how I saw it after only going AMD for decades. After 17 years I can say I have a great Intel CPU finally. I could have afforded the expensive Threadripper 1900x/1920x but after really looking at them it makes more sense getting a 1700x/1800x and overclocking the crap out of them although I have been told 4.1 Ghz is the stable limit.
