Thanks to the price drop on Zen+ due to the Zen 2 release, I recently built a Ryzen 5 2600 system as my new gaming rig. My old gaming machine had a i5-7400, and in pretty much every game the CPU bottleneck has disappeared, especially newer titles. Even older single-core-heavy games like CSGO have greatly improved with the new CPU. Basically every game in my collection can now run at 1440p60 (my monitor's native res) instead of being limited to 1080p60. Switching from a GeForce 1060 to a RX 580 allowed me to ramp up the quality at that resolution as well (in most games).

Further, now that Zen+ support in Linux and OpenBSD has improved, it is a stable enough platform for those OSes. My new rig is doing double duty as my main workstation now thanks to that support along with switching to an AMD GPU.

I honestly don't think Intel and Nvidia have a place in my home and office anymore. My media server is an ancient Dell PowerEdge T310 and it's still going strong, but it is limited on drive capacity and has issues transcoding more than one 1080p+ stream at a time, so I believe I'll be retiring it soon in favor of a Zen based custom build.

I'm not being funny - have you ever found any kind of bottleneck with that CPU? I'm still rocking an i7-4970K + 1080Ti and I have never ever seen the CPU being anywhere close to max load in any game, and I'm mostly playing in 1440p@60fps.

It was mostly with single-core-heavy (i.e. older) games. Newer multi-core games did very well on the i5, but better still on the six core Ryzen. I mostly play older games so my experience is likely different from most gamers.

Edit: An example from memory, the very old game Crysis stuttered badly at 1440p with the i5, it was only playable at 1080p (both resolutions with all graphics settings on highest/ultra); this was with the GTX 1060. When I first built the Ryzen system I carried over my GTX 1060, and was able to play that game at 1440p60 smooth as butter. Turning off vsync I was getting close to 100fps, whereas with the i5 and vsync off I was lucky to spike above 70, with average fps somewhere around 30-35. Moving to the RX 580 actually dropped the fps cap slightly with vsync off, but still allowed me to play at 60fps locked for a smoother experience overall.

In general, this was the same experience with all of my older games (Skyrim, Far Cry 2, Mirror's Edge, Rust, etc). With newer multi-core games like Doom 2016 and Far Cry 4 I never had any CPU bottleneck on the i5, and the new system marked an increase in graphic quality without sacrificing smoothness and resolution.

Does anyone know of good articles about parallelism in modern game engines? All I've been able to find is a couple of slides in a deck about Doom 2016.

I went from a i5-7600k to a i7-8700k and noticed decent performance increases with my GTX 1070. (CS is netoriously CPU bound). I've since upgraded to a 1080ti, I don't know how much performance was from the cpu upgrade and how much was due to the extra cores the rest of the system could use without interfering with the game.

Try Total War: Warhammer I/II with that machine. Does your i7-4970K have DDR4 RAM?

No, it's running DDR3 at 2333MHz. I mean I know it's not the latest and greatest but just as an example it plays Control at max settings at 1440p in locked 60fps, that's why I'm curious what kind of game could make it CPU-constrained because I just haven't ran into any yet. But then admittedly I haven't played any Warhammer games either.

Keep in mind too that your i7-4790K is much more powerful than my newer i5-7400 was. It’s almost on par with my Ryzen CPU. If you had a Haswell i5 instead of an i7 you’d likely have bottlenecks like I did.

GP said they're using i7-4970K; it is likely they meant i7-4790K. I'm using the i7-4770K. Which misses a certain virtualization hardware extension this K-series does not have, but the other ones in the series do have. Which pisses me off to not hand. For that fact alone, I won't buy an Intel CPU.

Thank you for the comparison, btw. Very useful.

To save non-PC-gamers a Googling: "CSGO" here refers to "Counter Strike: Global Offensive", a popular multi-player first-person shooter. It's part of the Counter-Strike series, which traces its roots back to the year 2000.

Counter-Strike came out in 1999. Source: I wasted most of 1999 playing Counter-Strike.

Counter-Strike was super fun during the time it took form (the beta versions from 0.5 to 5.2 ish). They tried a lot or different things, like dual wielding machine guns. The community was awesome also.

Beta 0.1 will always have a special place in my heart playing it for hours at the LAN shop down the street from me. Bonus was being able to troll people by flying my dead-player spectator through doors and opening them. People would get really mad - it was awesome.

Why is it being used as a subjective benchmark 19 years later? Haven't gamers moved on a dozen times since then?

CS:GO was released in 2012. Majors (international competitions sponsored by the developers) have a million dollar prize pool.

I am surprised most people on hackernews don't know but the CSGO engine is optimized for extreme frame rates. When played competitively they go for low resolution and ultra frame rates, thus the bottleneck isnt the GPU it becomes the CPU.

CS:GO is still played internationally and there are also professional tournaments. So I would say that it is still a relevant benchmark.

I agree that people still play it. But looking at the system requirements:

https://store.steampowered.com/app/730/CounterStrike_Global_...

I am hard-pressed to say that it looks like a suitable benchmark. It's hard to find a desktop CPU released in the past five years that can't provide good performance for a game like that.

People still benchmark CS:GO because it is one of the few games that is CPU bound that still actively being played today. It's one of the few games where a single core performance and memory latency has a big impact on overall performance.

Intel always had a huge lead on CS:GO until Zen 2 where the gap finally closes up, which is why a lot of people is referring to CS:GO benchmark when talking about Zen 2 in context of gaming.

actually a lot of pro players are streamers, so they at least need a good cpu for game+stream. some even have a setup with two computers. actually streaming games (especially new ones) still needs at least the i7's.

If you want to benchmark the CPU, then the CPU has to be the limiting factor performance-wise, meaning you don't want to be GPU bound.

It's usually easier to get to that point on older games. How this benchmark maps to real-world experience is, of course, a different matter.

Some CS Go players believe (and maybe is true) that having high FPSes live around 300 give them an advantage so they will try to make the FPS number as large as possible. Such a gamer will probably pay a ton more money to get from 2500 FPS to 300 FPS. They would also have monitor and mouse+ keyboards with low latency.

So from my reading this "elite/full time" gamers will still buy an expensive CPU if they get 10 extra frames (but forget that in real life your PC has more programs running in background so reality may not match the benchmarks)

For people wondering why, it has mainly to with the fact that mouse polling rates are tied to FPS meaning that you still have heavy incentive to go above the FPS your monitor could handle.

This video (https://www.youtube.com/watch?v=hjWSRTYV8e0) does a really good job explaining frame latency in CSGO and why you can benefit from running at FPS significantly higher than your refresh rate, and why vertical sync doesn't solve it like it should. The game is free now, so I'd highly recommend trying it out if you're doubtful about a smoothness difference between 100 and 250-300 FPS.

What? I've never heard this reasoning before.

The real reason is, I only really play csgo and pubg, I have X$ to spend on a CPU. Previously if you looked at them market, tier-to-tier amd vs intel - intel always was the stronger performer at the CSGO. Why spend X$ and get 250fps when you can spend the same and get 300fps?

You have a 300hz screen? Hint: it doesn't exist (for consumers at least) Current max is 270hz I believe, but a few years ago it was sub 250 hz

I'm not sure whether they update the minimum system requirements alongside the game. Keep in mind, CSGO is from 2012 and has received numerous updates, and looks, feels and sounds completely different today.

When I first bought my main laptop in 2017, I could play somewhat smoothly at 1080p, now I have to use 720p.

It's an interesting side-effect, before Steam and other content-platforms, games titles iterated much faster.

EDIT: Then again, when I think about CoD, I'll retract my last sentence.

That’s not the only game LTT uses to benchmark with, but they include it because of its popularity and I suspect because it normally runs at such insane frame rates that differences show up more readily—much easier to tell 220 FPS vs 240 FPS than 59.5 vs 60.

It's the more recent sequel that's being tested here.

You're talking about this video: https://www.youtube.com/watch?v=z3aEv3EzMyQ ?

On CSGO, AMD wins on average FPS, ties on 95%, and loses on 99%.

On Rainbow Six: Seige, AMD wins on average FPS, but loses on 95% and 99%.

On the other 3 games (Shadow of the Tomb Raider, Metro: Exodus, and Battlefield V), Intel wins all 3 categories. So overall, Intel still wins.
