Zen3 Ryzen 5000 serie

Yeah I noticed, senses oversaturated with reviews. Everything is great and awesome. Damn Ads everywhere.

 

 

Will the 5900X be slower on Single Core clock than the 5800X? I couldn't believe that. Then I'd return it 

[Jaws2002]

Looks like most 5950x are avtually boosting to 5.05GHz in single core boost. 

 

Tom's hardware review showed PBO auto overclocking hitting 5.15GHz.

 Tom's hardware is saying the 5900x is the top performer in gaming, because it's using two six core chiplets, but they allowed the chip to use all 32 MHz of l3 cache that's available in the chiplet. 

The 3800x has an advantage in a few, less intensive bulithreading titles, because it's a single CCX design and the latency generated by CCX to CCX communication is eliminated.

 

Looks pretty interesting.

Tom's hardware 5900x is hitting 2000MHz on the infinity fabric, so 4000MHz memory is possible, but we don't know yet what percentage of the chips can hit that speed.

 

Here's Tom hardware review. They have all cpus at once instead of the single CPU focus of GN.

A nice review from Computerbase,  a german hardwaresite:

[robbiec]

I went for the 5950X, 5900X is better value but I have use for the extra compute of the bigger brother. Now to see how long it takes to arrive

[Gambit21]

Well they’re sure not in a rush to get the 5900x out there.

 

Edit: or they were already there and gone by the time I checked at 8:00 am this morning 

 

Edit: Yep that was definitely the case - bastards.

Wow - Ryzen 7 5800x might be the best value of all.

[Voyager]

Well, at least according to the HW Unboxed 5950X review the 5950X did beat the 10900K in Squadrons, another DX11 flight like title @13:46 while the 3950X did not. 

 

I don't know if that will be relevant or not, but it could be a useful indicator. 

 

I'm really looking forward to our forum benchmarks here. 

[Gambit21]

 

Looks like the 5800X might be the surprise winner (bang for the buck)

 

5800X

 

I’m finding few reasons to spring for the 5900X.

[Voyager]

@Gambit21 At least according to the Anandtech review, the Zen 3 has much improved core to core latency within the CCX, and apparently is better than Intel's now, so long as you don't jump CCX: Core-to-Core Latency and Cache Performance - AMD Zen 3 Ryzen Deep Dive Review: 5950X, 5900X, 5800X and 5600X Tested

If the core to core latency is the root cause, or a major contributor to the Zen 2 performance deficit, we should see the 5800X end up out performing the 5900X in Il-2.

Yeah, we'll have to put this to the test next week. Especially in VR, as that amplifies the trouble. We'll need a benchmark we'll run at max details, but low-res next week, and log the frames.

[Voyager]

Very cool. Just saw that the local Microcenter still has a 5800X in stock, but we both should rebuild fund for a bit (had to replace a chunk of the AC last week) and I kind of want to go with the 5950X, so I (in theory) don't have to replace the CPU on this thing for a fairly long time.

 

With Il-2 and DCS being the only real things driving me to an upgrade, I am extremely interested in what the tests turn up.

 I would be much obliged if you would be willing to share your experience on IL2 performance of AMD's Zen 3, especially concerning VR.

 

@chiliwili69 made a standardized test as well a google doc document so that people can share their results combined with the specifics of their configuration (thread:https://forum.il2sturmovik.com/topic/56485-benchmark-for-cpuram-performance-remagen-4002-to-4005/ ). This has proved exceptionally useful in better understanding what benefits IL2's performance and what contributes less. @chiliwili69, do you think you would have the time and energy to 1) see if your standardised test is still up to date and 2) see if the google doc needs to be updated, maybe a new tab for the current IL2 version?

 

@SCG_Fenris_Wolf besides sharing your experience here, would you be so kind as to add your data to @chiliwili69's document? I made the statistical model using the data people were so kind to share to help identify what contributes to IL2's performance and I would be happy to update it if we can get new data from new hardware configurations. It would be incredibly useful for anyone considering upgrading their system with IL2's performance in mind.

That was a very good tool, but the track no longer works after the deferred rendering update. 

 

I wish the developers introduced a benchmark track, like that "black death" track we had in the older two versions of Il-2. 

I know, things change from version to version, but at least we would have a common tool to optimize our game and find the best hardware combinations for the game.

I managed to get 5900x and RTX 3090 FTW ultra. I have some issues with 5900x, propalby caused by MSI bios (x570 prestige creation). I am unable to get memory past 3200 mhz (with 3900x and 3900xt, a was able to get 3800 mgz, cl16, 1900 mhz FCLK on this board), so the performance of 5900x is not not ideal. But to my surprise, I am now mostly gpu limited in VR (HP Reverb, high preset, 2x MSAA, High clouds, high shadows,  118% steamvr SS). According to fpsvr, cpu frametimes are aroun 5ms, gpu frametimes 11-12ms (nearly 100 % gpu utilization) in dense BOM career mision.

Userbenchmark has been banned from /r/hardware because the guy running it repeatedly changes the way the benchmarks work to suit his view of which processors should be best. You can use it as a coarse-grained comparison tool but I wouldn't put much stock in it beyond that.

5800X

 

I’m finding few reasons to spring for the 5900X.

 

Depending on the workload, the 5600X could even be better, as it has fewer threads to keep at max boost, so it does better for lightly threaded workloads. 5600X + good water cooling might be the option I'm looking at in the new year.

  The Neo line is made for Ryzen. obviously, it works with intel as well, but the Neo line was tweaked to maximize Ryzen performance. For last gen Ryzens they released 3200Mhz-3800Mhz kits, because those speeds got the best out of Zen2.

     Now they released kits for the new version with speeds from 3600Mhz to 4000MHz, because this is what Zen3 likes.

Maybe some early BIOS issues. If i remember correctly, MSI was the first to release new BIOS for Zen3. AMD is also working on new AGESA firmware that should improve stability and help motherboards achieve that 2000Mhz Infinity fabric. So keep an eye on new BIOS updates.

Well, I can repeat what we did with the last Remagen track but this time using a mission which in theory should always work (regardeless of the new upddates).

I wanted to know first what Jason or Dev team have on mind (who knows if they will incorporate an in-game benchmark). But Jason and they team didn´t give a clue about what they think, so we sadly can not count with them (they have tons of work alrady on the table).

 

I am going to try the mission that @SYN_Vander kindly created in the Nvidia thread and I will see if it can be used as a benchmark.

 

If the mission is usable to track performance then we could use it to measure perfomance. I was thinking in two tests in 2D monitor:

 

1. CPU/RAM test: With resolution 1080p, here we will put Ultra preset (maximum of polygons) and most of other settings to max (except cloud to low, since cloud load just GPU)

 

2. GPU test: With resolution 4K (or 2K), using Low preset, and most of settings to max including clouds.

 

The problem is that not all people has 4K or 2K monitors.

 

Then, anyone with a VR device can also run nay of the test using a low SS to test CPU/RAM and a high SS to test GPU.

 

If someone else would like to do all this work and collect all the tests in a similar table I will be more than happy to assit him. Otherwise I can try to repeat what I did.

Thanks for the info. Can you run HP Reverb with reprojection turned off at CONSTANT 90Hz in career mode ? (I mean  at 100% of Reverb's native resolution with high preset, 2x MSAA, High clouds, high shadows).

Seems to be widespread issue. Someone had some succes with reverting older bios and setting ram manually, but i am too tired to try it now. I can't count how many times i have flashed bios and changed memory today.... So I just hope for new bios soon.

Well, it is nearly constant 90 hz, but not quite, there are still ocasional drops, sometimes even to 60's. Clouds seems to be problem, and heavy populated areas too. It is definitely better than 3900xt/9700K 5.2Ghz + 2080Ti's on my other rigs, but to be honest, i have hoped for more... I have yet to do some tweaks, though...

Btw

 

Didn't get much time to test yet. In the week my primary goals are to:

 

1. Find out best Ryzen configuration: Test Ryzen 5900x performance in IL-2 using different RAM configurations (4x8GB 4000MHz CL18 Vs 2x8GB 4000MHz CL18 Vs similar 2/4x8GB 3600MHz CLx not yet decided yet).

2. Benchmark fastest result and put it on here. @chiliwili69, would you have another heavyweight Remagen test for us (max/ultra details, VR, heavy load to have the CPUs suffer) for this new round of CPU generation? 

3. If Reverb G2 has arrived, compare Reverb G2 Vs Pimax 8KX for IL-2's use-case with soft secondary factors such as performance, spotting, and more.

It does look good!

 

That said, I think just about every reviewer is making the wrong call on the 5800x. As far as I can see, this is the unsung sweet spot despite the “it’s $50 too expensive” whining.

 

The fact of the matter is that you’re basically (more or less) getting. 5900x performance across the board (including productivity, 3D etc) for $100 less.

 

Over and over I keep wondering if their even looking at their own benchmarks.

 

Based on gaming and 3D benchmarks I see no reason to spring for the 5900x, but in my use case I also can’t justify going down to the 5600. 5800x offers better future proofing and in my case faster renders and it beats the 5900x in several cases - what’s not to love?

 

YMMV of course. 

 

 

[Jaws2002]

One thing i noticed about 5800x in reviews is that the boost clock stays stable and isn't fluctuating as bad as in the 5900x and 5950x.  While many reviewers think it's too expensive for an eight core CPU, I think it has a very good combination of TDP, Boost and low latency that comes from the single CCX.

 The 5900X has a bit more cache per core, more cores higher boost ,but it gets the latency that comes with jumping CCX..

 

I'm still debating if it's going to be 5900x or 5950X. 5900x makes more sense for gaming, but in multithreaded loads, my 3950x still beats it.... and that 5.05 GHz that most 5950x chips get does look cool. ?

I think they are looking, but their "mainstream gaming" use case is different than ours in the sim world. The argument they'd make is you can't tell the difference between the chips when you are GPU bound, and most players should be GPU bound. If you're CPU bound, you're trying to tell the difference between 130 and 140 FPS, which no-one actually can see, so they write off the extra performance as not being worth the cash.

 

Especially in VR we need as much oomph as we can get. I wonder if the giant 32MB cache is able to hold a lot more of the core IL2 data? That might be why someone's getting insanely low frame times -- 5ms is just amazing for a mission with lots of Ai. If you have a single CCX and a lot of critical data in cache, that could get the good results.

Yep...and I've seen enough CPU bound slowdown in our flight sim (even when FPS remain stable) to not leave any horsepower on the table that I don't have to.

Thus the 5600 just isn't an option for me. I I was a traditional "gamer" then sure.

 

Technically I have the budget for the 5900X if I want to go that way, so I'm waffling a bit.

I have 2X16 since that's just what the kit was, and I lack the bandwidth and time to spin down that path currently.

 

Even with my 3D rendering work etc, I just can't justify the 5950...hell even my current overclocked 1700 smokes at that stuff.

[SCG_Fenris_Wolf]

That 4x8GB would be faster"on Ryzen" is simply lack of [deleted]. That'd get throttled, as most x570 are Daisy-Chained. But I will try in field test, basically. This is no secret that performance will be different, it should be bound to the memory topology of the board. If it's linked with T-topology, you'll get the better response from call with less latency across all for DIMMs. My board's topology is daisy-chained so I heavily doubt it'll improve performance with 4 DIMMs - instead it should lose performance. So, to get Dual Ranked properly, I'd need 2x16GB. Damn.

 

And if 5900X have shown bad behaviour at high boosts that's probably owed to lower VRM quality, with less real steps to adjust voltage. So basically unfit boards. Here is a list of the boards' properties, so you can make an educated purchasing decision:

 

https://docs.google.com/spreadsheets/d/1wmsTYK9Z3-jUX5LGRoFnsZYZiW1pfiDZnKCjaXyzd1o

 

 

P.S. It's safe to say already that 4000MHz cl18 DDR4 RAM should be favoured to match the infinity fabric of Zen3 at 2000MHz. You can then tighten timings as far as you can but that's the first aim. More time in the afternoon.

Edited November 11, 2020 by SCG_Fenris_Wolf

The reason of dual rank per channel giving more performance than single rank is because there is higher effective memory bandwith for the same memory frequency. Both intel and ryzen are bennefited but as the Gamers Nexus testing showed the gains are more significant in the 5000 series compared to intel.

Here a video of Buildzoid rambling about the topic from earlier this year.

As I said, only if the topology supports it. It's not complicated, but not *that* trivial.

Yep...and I've seen enough CPU bound slowdown in our flight sim (even when FPS remain stable) to not leave any horsepower on the table that I don't have to.

Thus the 5600 just isn't an option for me. I I was a traditional "gamer" then sure.

 

I think this graph tells the story, this is stock CPU frequency of the 5600X (yellow line) vs the 5800X (green line). The higher boost will give more headroom for stuff like IL2, but for the majority of games it's not worth the $150 more than the 5600X, and it's only $100 below the 5900X which gets you two more cores for productivity workloads.

 

 

But for IL2, 5800X could give you a little extra over the 5600X, for sure.

Pretty impressive how steady the 5600x and 5800x are holding the boost. Perfect straight line. No dips. I think all those dips in 5950x and 5900x graphs are happening when the main thread is jumping to the other CCX. Either that or the CPUs are much faster hitting the maximum power, or thermal limit.

 

 Compared to the last generation even this Ryzen 9 CPUs are holding the boost much better.

The way I understand it the motherboard memory topogoly matters mostly for high frequency stability, if you want to get into +4000s MT/s overclocks. I don't know if it affects raw performance. And afaik most X570 motherboards are daysi chained anyway. I don't know which one specifically GN used for their review, I'll ask them.

@Jaws2002 It looks like the 5600X and 5800X chips could hit the 5950X numbers, but they're running into the hardwired boost cap instead.
