AMD Ryzen 1800X

Anonymous — Wed, 15 Mar 2017 13:36:36 GMT

Has anyone test an AMD Ryzen 1800X with a motherboard with a X370 chipset?

I have a year old 5960X (http://ark.intel.com/products/82930/Intel-Core-i7-5960X-Processor-Extreme-Edition-20M-Cache-up-to-3_50-GHz)

8 cores, overclocked to 4.1, with memories at 2666 quad channel

Ryzen can provide the same 8 cores, but can get 3200Mhz memory but it's only dual channel, which affects largely the performance theoretically.

Anyone has real data?

Could I suggest you check out this link, I think it should answer your question. CFD Hardware Recommendations

(I have no direct experience with this chipset)

No what i want to know beside the memory isssue is this

Geekbench tells a similar story, particularly in the single-threaded tests, where Ryzen boasts a floating point score almost as high as the i7-6900K, but 35 percent slower in integer. As Peter pointed out in his deep dive into Ryzen, that floating point performance parity is only applicable if the app in question doesn't take advantage of the AVX instructions that favour the 256-bit AVX FMA units inside Broadwell-E. Most consumer apps don't use AVX instructions, but those invested in HPC will take a performance hit with Ryzen.

I know this isn't exactly what you are looking for but since I cant really find any information out there as well I figure I post. If you have something I can run I would be happy to give you a result.

The company that I work for has a small group that uses 3DSMax and are trying to figure out what hardware to upgrade some of their machines. I am a software developer so I don't no exactly what is in the max project but I was told it was one of their more short CPU heavy renders for a client that they have done recently. Granted this is not a very thorough comparison as I have a fresh install of windows and they tested several year old machines.

Not tested by me and none are overclocked

~3 year old i5 15:37

~3 year old i7 7:50

~5 year old 10 core dual socket xeon 5:30

~2 year old 12 core dual socket xeon 2:50

What I tested

Ryzen 1700x

Stock Frequency at 2400Mhz ram 3:38

Stock Frequency at 3200Mhz ram 3:03

Overclocked to 3.8 at 2400Mhz ram 3:17

Overclocked to 3.8 at 3200Mhz ram 2:51

The new ryzen chips do like the additional ram frequency as it allows their compute units to communicate at a faster frequency.

Thank you for your feedback, it looks encouraging.

I'm waiting now for the Amd Threadripper 16 cores 1998x - Since besides the clock it has quad-channel memory, and usable 16 cores by CFD.

I have threadripper and it runs autocad like crap =(

first time ever having buyers remorse on a pc

With 16 physical cores? Depends what you are running and the clock speed but that should be quite fast...

I'm talking strictly autocad.

we use microvellum at work with autocad

my i7 still smokes it across the board.

The thread ripper is going to be a great cpu when companies start leveraging it

when autodesk starts using DX 12 for autocad, then it's different story.

but for now i7 7700K or better for autocad environment

I can get it to perform better when I oc it and turn it into a 4 core processor

but then I can oc my i7 too which kind of defeats the point.

SC IPC still favors intel

I actually have my threadripper for sale

Once the patches come out for intel I may consider an i9 after I see what performance hit if any it's going to take from meltdown and spectre

the quad channel memory is great as the previous poster talked about

on synthetics i went from 32 gig per second to 76 gig per sec band with

but you don't see that in the autocad environment at all

just the whole experience with hurts my head

even with faster drives and ram on my threadripper versus the 7700

the load times are slower and the response working in it just hurts my head

it all comes down the software =(

-BEEN USING AMD RUZEN 1700X SINCE APRIL 2017.

-CUSTOM UPGRADE 12 WORKSTATIONS WITH AMD RYZEN RANGE FROM 1700 TO 1800X WITH ASUS PRIME MOTHERBOARD.

-FOR RENDERING USING ALL 16 THREADS IS GREAT.

-ONE CAN PICK UP AMD 1700X AS LOW AS $269 AND AMD 1700 AS $239 FROM MICROCENTER.

-SAVED TONS OF MONEY GREAT PERFORMANCE NO TURNING BACK.

-BY THE WAY AMD RYZEN CPU RUN GREAT ON WINDOW 7 TOO. (ASUS MB HAS DRIVERS)

for sure the rendering is amazing. but the trade off for that to me isn't worth it yet. Not until autodesk and other companies upgrade how they code and/or start using dx12
