Is a 5Ghz Ryzen Cpu coming?

I would grab a 3700x or 3800x and try that then look at a new platform if it's still an issue.


I love this justification for a 6% CPU difference in gaming making a difference in playability..... if in future that few percentage is an issue you will be upgrading the whole computer anyway. 6% is NOTHING, this is bonkers amounts of FUD.

No they didn't make all latency worse, mr blanket statement, are you related to Shintai? Only increase was memory latency which accompanied an increase in throughput and maximum rate.

It’s not the 6%. It’s large spikes of CPU side lag even though the CPU is at a decent temp and maybe 30% usage.

Maybe I’ll try slapping a USB PCIe card in. It’s the only thing I can think of. Maybe I’ll give it it’s own controller on the mobo before I do that, since it’d cut my PCIe lanes on my GPU.

I don’t feel like buying a new mobo or waterblock so I am still leaning towards a 3950x. I basically want the high boost over the core count. Supposed to be 4.7Ghz, close to 5. But I need to solve this nonsense first.

It's not my logic.

See DuronBurgerMan's post above. Ryzen 3000 has been tested to have lower IPC at the same clockspeed in gaming. Worse, there are still frametime issues that affect the 0.1% lows, and those are the issues that you would feel.


Further: your position makes the basic fallacious assumption concerning the relationship of performance at particular resolutions. We use 'faster' and 'slower' for a reason: if a GPU twice as fast as a 2080Ti were available, and that's something that we can bet on happening eventually, 1080p performance on a 2080Ti would certainly be applicable to that future GPU at 1440p and even 4k.

Buying a CPU because it's 'fast enough at 1440p / 4k today' makes little sense if like most people that CPU would be kept through multiple GPU upgrades.

This is one of those things that I feel has been talked to death these days. And I've sure contributed on that count!

A good heuristic to use at this point for the high end mainstream CPUs is this: AMD is one generation ahead of Intel in terms of multithreaded performance, and it is one generation behind Intel in gaming/lightly threaded performance. If you buy a high-end AM4 CPU, you're getting tomorrow's Intel workstation performance (successors to 9900k), but yesterday's Intel gaming performance (~8700k). The tradeoff makes sense for a lot of folks. It doesn't make sense for everybody. I don't really understand why this is hard for folks to grok. It's neither good nor bad. It just is. As you noted quite poetically, if you don't buy the best product for your use case, you're making a donation to big a mega corp (and do they need your pity? I think not).

In the mid-range, AMD dominates pretty well. Despite higher average FPS from the 9600k vs 3600 and 3600X, I would go Ryzen here even as a pure gamer. GN noted that frametime performance was better with the 3600 (and X) over the 9600k, and the lack of those extra threads means if games get any more thread aware than they are today, the 9600k will suffer. Intel non-k parts are a nonstarter. Wouldn't touch as an enthusiast.

The FUD is claiming that a 6% average delta is representative of what a single end-user would experience. That would only be true if they played every game in the benchmark in equal proportion. Let's see how many people buy that argument.

And yes, AMD absolutely did make latency worse, literally by design. But of course you didn't link memory latency, because that wouldn't support your fallacious rebuttal

They made memory latency worse. But then they also mitigated this with boatloads of extra cache and a number of other tricks. Memory latency is a tad worse than Zen+, but roundabout equivalent to Zen. That is actually a pretty herculean effort given the radical changes in Zen 2. This link demonstrates it pretty well. Overall an excellent job of mitigating the costs inherent in the chiplet concept. But the numbers don't lie. Latency is worse than Zen+ (and was always worse than Skylake variants):

I'm here because I'm a sperg about computer hardware, and always have been since I was a kid with my first Commodore 64. Yes, yes, I can justify it given my work, and my gaming. But frankly, I'd still be in this hobby even if I objectively couldn't use it.

People buy supercars and sports cars they'll never (or rarely) race for more or less the same reasons. Is overclocking an already-fast processor really about real-world performance? Most of the time, no. It's because we can. Same thing with "pushing gaming limits" and tweaking for higher FPS than the human eye can even see, or running round after round of Cinebench trying to beat your last record.

So you are having issues with a Zen+ you (based on your signature) or did you replace one with a Zen2 and are having an issue?

Which Mobo, AGESA code, and chipset drivers? How fast is your ram? OC'd? Fully stress tested?

If you are using the VII in the rig with the issue, what driver are you using? I'd like to report it internally and see if anyone else can replicate it to try to help you out.

That sounds odd. Even my 2700X doesn't do that. Lower average FPS than equivalent-gen Intel CPUs, sure, but I don't see large spikes of CPU lag. Is there a specific game this is occurring in, or just in general?

Just in VR afaik. I figure something is getting clogged up somewhere, maybe the USB ports. I remember that being an issue for some back in the day. Problem with a USB PCIe addon card is it’d drop my 2080ti down to 8 lanes.

I am debating if I want to go 3950x.

Current rig is 2700x/2080ti. MSI Gaming Pro 450B. Up to date with drivers off msi’s page. 16GB 2933. I’ve been using it for about a year without any other issues.

I don’t want to derail the thread anymore. Idiotincharge’s post triggered me. It seems I only run into this stuff with AMD cpus / gpus. I don’t know if it’s a lack of vendor quality control or what. I also know people have issues with the Vive wireless adapter and AMD.

I do have a perceived lower QC with AMD. Between freesync being so wide of a spec, the mobos that don’t have enough space for the 3xxx AGESA code, ect. The flip side is it seems everyday Intel has security issues that drop performance (and hence why AMD is doing so well).

I’ll go with a 3950x if I can resolve this (and use my mobo). Hell, probably a long shot given the current chips, maybe we can OC it from 4.7 to 5Ghz just for the epeen. The higher boost is why I want that chip. The highest IPC possible.

Ah, I don't bother with VR. Interesting that it could be a USB problem. Crappy drivers or chipset issue?

Yeah. I disabled the cameras on the Vive Pro and it fixed most of it.

Looking at the datasheet there’s two USB ports that go directly the the CPU. I’ll try those. Maybe the chipset does a shitty job dealing with latency, who knows.
