Re: AC:Odyssey requires AVX, won't run on a Pentium Gold

This is starting to sound like more QC and QA issues more then anything else. The suits didn't want to spend the extra time and $$$$ to ensure that product would work on older and "obscure" platforms. The Jaguar CPUs in both console families support AVX. It's likely that the dev team led ...

Re: Debating Core i5 8400 vs Ryzen 2600

The 1700 -> 7800X seems like a side-grade to me but for $200 more. I dunno. Sounds like the path is set. I mean, pretty much. For more weakly threaded workloads it'll be decisively quicker, but in aggregate they'll trade blows back and forth outside of AVX flogging, with the 7800x taking more than ...

No, that's what I mean. With the exception of a dedicated AVX512 number crunching node, either Coffeelake or Zen is going to be better. Not if your workloads easily scale beyond 6 and 8-cores and/or need more than sixteen PCIe lanes + whatever is free on the PCH/Southbridge that is found on Coffee ...

Re: Debating Core i5 8400 vs Ryzen 2600

If I end up building around the free-to-me LGA 2066 board, the Ryzen 1700 I've been using would probably end up being retooled to be that game-and-desktop machine. But this has gone off topic to be sure, and I'll lock the thread if that's appropriate. Well, as long as you're getting what you want t...

Re: Debating Core i5 8400 vs Ryzen 2600

I'd rather get an 8400 than invest in that. Same. The fact he'll have to buy quad-channel memory to get the most out of it negates any savings by skipping a motherboard. Also, the talk of many-core CPUs has kind of veered away from the stated purpose of the machine: "regular family desktop stu...

If I were to go with any of them, it'd probably be the 7800X. To say Ryzen threw a wrench into the planned economics of this platform would be understatement.

It looks like my Micro Center's got the 8400 in stock for $200. Intel's power usage is lower, and per thread it's punchy. And yes, the 2600X has more threads, but my workstation's already a Ryzen 1700. Six really might be enough here. Mind, I'm not committing to anything until next week, when the ca...

Debating Core i5 8400 vs Ryzen 2600

I'm in the process of selling off a lot of older hardware to scare up money for a new Windows machine. Aside from regular family desktop stuff, it's going to have a 1070 Ti and be up for pretty much any game around at 1440p. Given this use case I'm inclined to go with a Ryzen 2600, but the Core i5 8...

Re: Threadripper 2990wx experiences

I'm not sure how you're loading the cores, but I'd guess somewhere between 32 and 64 threads you're hitting the limits of Threadripper's quad-channel memory bandwidth. It's interesting it falls off so dramatically after 32, but based on this data point it appears the 2990WX is a fundamentally flawe...

Re: Threadripper 2990wx experiences

It sounds like the Ryzen memory controller's generally quite capable. Could it be issues with high latency while fetching from the L3 cache across CCXes? Some of that's bound to improve over time with scheduler modifications. Unlikely. If he's running 32 to 64 independent monte-carlo simulations, t...

More specifically, for the Monte Carlo runs I'm doing now, here are the performance gains: 8 to 16 threads ---> 1.7 times gai...
