I know there is a lot of RAM discussion and I was wondering if there is a way to set Command Rate at 1 instead of the normal 2. From what I remember this boosts performance a lot.

There should be a way to set CR1, though you might need an AGESA 1.0.0.6 BIOS to do it. You will also have to disable to geardown mode since it will cause the controller to ignore the set command rate.

I got this goin'

Grimey Drawer

Regarding IPC, if I am currently running a i5-4690K @4.2GHz all four cores, would switching to a Ryzen 1700 clocked up to, say, 3.8GHz be a lateral move, upgrade, or downgrade for 1-4 core operations? I've been on the fence since the Ryzen release. On the one hand, I can definitely use the 8 cores for software build time (current project takes about 7 minutes to build maxing out all 4 cores) and video encoding, but I don't want to take a step backward on VR gaming where I feel like I am already on the edge. I'd hate to spend a grand to upgrade my 3 year old machine only to find I've actually lost performance on some workloads.

Honestly, I would ride what you got unless you really need to speed up that build time. What you have will probably be a tiny bit faster in most games at vive/rift resolutions, and it has the advantage of already being paid for.

What if you had two computers? Keep the one you have for games, and build an R7 for work and video encoding? For a grand you could do a whole new Ryzen PC.

Buuuuuut was that actually at 4Ghz the whole time?! Was it like overclocked or something? That is f'n impressive either way.. I have to wonder what kind of power draw that was sucking down. To be honest I assumed at a full 16c load it would run more like 3.2Ghz per core or whatever.

Pretty close to same single-threaded perf, maybe just a touch behind the 4690K in some tasks. But, you'd have twice the multi-threaded performance.

A build server or workstation is a great use for Ryzen 7. As a build server, just make sure you have enough jobs to occupy it (each job is usually single-threaded). Video encoding scales out really well too. I would actually not clock the 1700 up at all for that stuff, just let it run its native speed, the 1700 is real efficient (and turning on OC control disables power management - even undervolts) and those are basically just pure multi-threaded loads.

If you want more in VR then overclock your 4690K. You've got little to lose at this point, it's halfway through its useful life-ish, if you assume people like to change every five years or so. No reasonable overclock is going to harm it at this point. VR does like single-threaded performance, although again Ryzen will not be far behind your current single-threaded perf, and some stuff like Rift image processing for its cameras do really need a core or two of their own. Vive is significantly lighter on the CPU, and you probably want to go with a Haswell/Skylake/Kaby Lake K-series if you can.

(of course I am one to talk, I am running my 5820K at 4.13 GHz all-core at stock voltages )

I have a Sandy-Bridge, a K version on an ASUS motherboard. In all my (almost) 5 years of ownership, the only overclock I did is push the "performance" button in the BIOS. It went to 4.something Ghz and stayed there for a few years. Since last year it went down to its normal clock for some weird reason. I'm wondering if i should buy a K CPU or just save a few bucks and get a small-ish cooler and not bother since, well ... I seem to be too lazy to go all out on it so far. Mess with voltages and poo poo ... meh, it's not 1999 anymore.

Huh. Would a 2600k @ 4.3GHz and 16GB DDR3 RAM (not OC'd) to a modern Ryzen system with fast-ish RAM be a good upgrade for VR?

I really paid no attention to AMD for a long time. Was the generation before Ryzen really that bad?

SwissArmyDruid

Threadripper unboxing shows that AMD is including a T20 Torx driver in the box, for anyone who was worried.

Also, yes. Holy god, yes, it was bad. Imagine an eight-core chip with no multithreading, with single-threaded performance half that of an Intel chip with an equivalent thread count. That was basically Bulldozer at launch. AMD wanted to move the industry to multithreading instead of continuing to chase 5 GHz and bet the farm on it, and the rest of the industry just shrugged, taking their time to expand into 4c8t instead of 8c8t.

Multithreading applications STILL isn't at a point where Bulldozer could have thrived, but AMD's insistence on forgoing single-threaded performance all in the pursuit of multi-threaded when most everything was starting to figure out how to use more than two threads effectively was a catastrophic step back from K10.

I don't think it's a stretch to say that if not for Bulldozer, AMD might still own Adreno at this point.

Yes, bulldozer as a whole was pretty awful. I didn't really keep up with it in detail, but I believe all bulldozer based architectures were a step backwards in terms of IPC even when compared to Phenom II.

you can read this for some information from back then: http://techreport.com/review/21813/...dozer-processor

here's a paragraph from the conclusion:

Scott Wasson posted:

Faced with such results, AMD likes to talk about how Bulldozer is a "forward-looking" architecture aimed at "tomorrow's workloads" that will benefit greatly from future compiler and OS optimizations. That is, I am sure, to some degree true. Yet when I hear those words, I can't help but get flashbacks to the days of the Pentium 4, when Intel said almost the exact same things—right up until it gave up on the architecture and went back the P6. I'm not suggesting AMD will need to make such a massive course correction, but I am not easily sold on CPUs that don't run today's existing code well, especially the nicely multithreaded and optimized code in a test suite like ours. The reality on most user desktops is likely to be much harsher.

scott was right

Also having an iGPU to pass through is kind of nice when you're running two OSes on two monitors, saves a bit power over an extra add-in card although PCI slots are hardly a problem with TR.

OBAMA DID NOTHING WRONG


A casual Google search didn't bring up anything conclusive - would populating all 4 of my ram slots (from my current 2) mean I can't run them at native 2933mhz?

The manual for my asrock b350 mobo seems to point at lower speeds for 4 sticks versus 2 but I'm not sure.

You will most likely be limited to lower speeds with all 4 slots populated since this puts more work on the memory controller.

I bought in near the end of that generation, I upgraded from a Phenom II to an AMD FX 8350 which has 4 x 2 core modules @ 4ghz, presenting 8 cores to the OS, though each module shares an FPU. Honestly, the amount of making GBS threads on this CPU from the community always felt very unwarranted and near twilight zoneish to me. I use very high end Intel workstations at the office (rare company that is upgrade happy), but my personal machine that I come home to has never really felt under powered aside from having much less / slower ram. I'm a professional software developer that multitasks like crazy - VMs, large software builds, Chrome occasionally running like 80 pornhub tabs, you name it. I could easily OC this chip, but I instead undervolt it from stock (1.45v?) to .875v for power savings / quieter fan speed

Granted, I don't game a lot, but when I have picked up the latest hotness and found performance lacking, a GPU upgrade fixed the issue entirely.

Was coming here to post that, it's interesting to note that Ryzen actually has really good L2 and L3 cache when taken from a throughput+latency perspective, but it seems it's L1 is a bit trash. IMC actually seems pretty good considering it's going up against quad channel solutions. Skylake-X seems throughput focused and consistently has latency issues, is it possible Intel rushed this and can fix that in the future?

But yeah Broadwell-E dunks on Skylake-X pretty drat hard.

It's not an issue of "underpowered", just that you could buy an i5 for the same price for most of the 8350's life that would outperform it in every way while using less power.

The revised Vishera chips were OK, they just weren't competitive with Intel. You'd also have been fine cruising on an overclocked late core 2 quad.
