Ryzen v i7 debate!

[flipbook]

Just wondering if anyone has jumped ship to AMD since Ryzen came out and can share their experiences.

I'm still looking to build a new sim machine for me and a couple of workstations. I may get the workstations as Ryzen but for my machine I'm still inclined to go for the i7 6850/6900 even though they are stupid expensive

Ryzen benchamrks look good so far but would like to see some simulation benchmarks (I know memory plays a bigger part etc).

I have the same question. I'm about to build a new sim machine and I was planning to get the i7 6950X but it's $1600 so I'm briefly hesitating. I've heard that a Ryzen can come within the ballpark of a 6900K but of course doesn't have a chance of beating one. That said, the Ryzen is half the cost of a 6900K so that's something to consider. I've been staring at this benchmark site for days now: https://www.cpubenchmark.net/high_end_cpus.html

It's possible that two separate computers with two Ryzens may push through more render frames than a single computer with a 6900K but if we are talking simulations - then perhaps one machine with a beefier cpu is the only option.

I'd love to hear from anyone who has thoughts on this

would it be possible for Chaos Group to create a Phoenix simulation benchmark tool ?
Would be good to be able to compare different computer setups...

I'm using two Ryzens (1700 and 1800X) and they are both crushing the sims I throw at them. I don't have a 6900K rig to compare against, or a reference scene to test, though we could use one of the example scenes as a test. I suppose it would also help to use the same version of 3dsmax, I'm on 2014.

Thats a good idea but the sims tend to be more dependent on memory and I/O speeds (giving more variables) ... I'd happily try it though.

[Svetlin.Nikolov]

Indeed, as Adam said, sims depend on several hardware factors, so with the same CPU but different board or storage you'd get different results, which makes comparing harder.

[waaazoo]

yes, I agree that it's difficult to compare, but at least we could do "some" comparision. Also, you are all simming on Max, and I'm simming on Maya
I did, for example a test. Batch simming on two very different computers. One is a Dual Xeon E5-2683 V3 with 32Gb Ram DDR4, the other a i7-3930K (OC4.2Ghz) with 32Gb Ram DDR3. Both have SSD drives.
The sim is actually nearly faster on the i7...
I would love to be able to compare with a new Ryzen system (with fast memory, good MB, fast drives)

I can tell you from my experience. We had i7-6700k at 4 Ghz and now we are using 10 core 7900X at 3.3 Ghz we are getting about twice the speed for calculations. I imagine 18 core might do it 3 times the speed.

this is cool thanks for the info
