RTX 3080 Benchmarks on RYZEN CPUs – Scaling from 1300X to 3950X!

by birtanpublished on October 3, 2020

So the rtx 3080 is already here and finding one is already almost impossible but we're still going to come up with some cool content and in this case we want to focus on amd's ryzen scaling you see if you caught our launch day coverage which you can check it out right over here and i hope you didn't miss that we approached this release differently from the others honestly it was a foregone conclusion that the rtx 3080 can beat the fastest gpu from last generation we also wondered could

It dominate when you install it onto an older system you know could it give you performance or massive performance improvement without giving your gaming rig a complete facelift instead of only pairing the 3080 with a super expensive cpu that's out of most people's budget we install it into a gaming system you could buy three years ago and the results well it turned out that an older i7 7700k only lost by a few frames per second at 1440p and was pretty much neck to neck with

The 10900k at 4k it was really impressive to see but you know what's even more impressive amd's dominance in the processor market right now there aren't just the more affordable option anymore ryzen is now the right choice for most users also 3rd gen ryzen cpus and b550 motherboards are no-brainers for people looking for a more affordable system upgrade so this video's purpose is to show ryzen users what they can expect with an rtx 3080 and whether or not

If they need to spend a lot of money to get the best out of it also just like the previous video we will be comparing current ryzen cpus to the ones that were launched almost three years ago so let's get to that right after this say hello to proper airflow with be quiet purebase 500dx a compact mid tower with a mesh front panel and three 140 millimeter purewings 2 fans that are silent and capable enjoy tasteful argp illumination a type c port and an easy case to work in check it out

Below okay so let's get some housekeeping out of the way before diving right into the benchmarks what we're going with this video is sort of bookmarking the first and third gen ryzen desktop lineups it all boils down to price on one hand we're using a four core four thread ryzen 3 1300x which was one of the most popular budget processors back when it was launched in 2017 for about 130 us dollars and yeah i know that using a

Super high-end gpu on an entry-level cpu might sound completely nuts but it should give us some interesting baseline for the benchmarks of the results plus why not the best equivalent to that right now is the ryzen 3 3100 that goes for about 120 it also is a native four core cpu but amd is now enabled smt so it has eight processing threats on the higher end is the ryzen 7 1700x which has eight cores and 16 threads a lot of people chose it over the 1800s since it was a hundred dollars

Less and it offered pretty similar performance especially in gaming the equivalent nowadays is the 16 thread 3800 xt which was launched at 400 and it happens to be our favorite cpu right now this thing's just awesome on paper it has the same 4.7 gigahertz boost clock as the 3900 xt and the 3950x but our sample actually hits higher sustained frequencies in games than either of those basically that means it's a better choice for a pure gaming system the last minute addition

For us was the 3950x which mike literally decided to throw into the test bench uh last minute and of course there's intel's 10900k since it's the fastest cpu right now so it's the benchmark all others will be measured against now you might be wondering why there aren't any other processors here and i guess i can just build beans right now believe it or not the actual differences between the 1300x and the highest 10 ryzen cpus aren't that big as you might expect in gaming at least so the other processors

Just sort of fall into a narrow window as for the rest of the test system specs they're pretty identical except for the memory on first gen ryzen it just doesn't like the speeds in excess of 3000 megahertz so we kept it at that speed otherwise all the test systems were configured identically since this is a super high-end gpu we're going to be testing at 1440p and 4k only expect to see 1080p come back when we start looking at the 3070 though

Also if you're using an ultrawide 3440×1440 monitor you can expect results that are a bit lower than 1440p but not by a huge amount so how does ryzen react when you hook it up to the fastest gpu right now well let's find out starting with call of duty and right away you'll see that there's literally no visual difference between the 10900k the 3800 xt and the 3850x things do tighten up a bit more at 4k but the older cpus are still pretty far behind

But like i said in other videos the iw8 engine loves new architectures frequencies and more cores at higher resolutions like these cs go still tends to be a bit cp bottlenecked at 1440p but the number of processing threads really doesn't make an impact this is all about how well a given architecture can perform in lightly threaded operations which is why the first gen ryzen cpus fall behind even at 4k another thing you might start to see as these benchmarks go by is while the 1300x

Posts okay averages its quad core layout negatively impacts the overall smoothness of one percent lows in a lot of titles in doom you can start seeing evidence of gp bottlenecking in 1440p so all the processors are pretty close to one another that situation gets even more apparent at 4k it's really amazing to see what happens when a game developer actually takes time to optimize their game properly flight simulator 2020 is the exact opposite of doom it's super demanding on all of your

Systems resources but it seems to love high cpu clocks and more than four processing threads then again this could come down to optimizations too because man oh man this is a game that's really hard to run on any gaming rig zero dawn brings us back to gp bottlenecking again that means all of the processors here perform almost identically to one another regardless of their generation that's good to see for sure since you could have any cpu from the 1300x

To the 3950x and expect pretty similar frame rates in this game with an rtx 3080. moving on to rainbow six siege and yep we have another game that's gpu limited even at 1440p 4k ends up being pretty much a tie even if you're rocking a 130 cpu from three years ago in the last video i mentioned the unreal engine has a lot of optimizations built into it for newer architectures and these results prove it but only at 1440p here it's obvious that the cpus are

Becoming a bottleneck at least at the high end but when you switch over to 4k it's more of the same with a straight line between every single one of those processors there really isn't much to say about red dead redemption 2 it's all gpu bound what's interesting is it seems like rockstar's many patches have fixed some of the massive issues this game used to have with cpu scaling so now regardless of whether you're playing at 1440p or 4k the graphics card will choke long

Before most processors become a problem for performance but again that quad-core architecture of the 1300x means it's one percent lows results take a beating one of the main problems with overwatch is that its engine is limited to 300 frames per second and it looks like all of these systems here can hit pretty close to that mark consistently with the rtx 3080 installed at 4k there's a bit of a gpu limitation but honestly at these kind of frame rates upgrading the cpu to the best that's

Available right now isn't going to make a massive difference well that ended up busting a lot of preconceptions didn't it you see as i mentioned in our launch date coverage um using the fastest cpu to benchmark graphics cards eliminates bottlenecks but it might give viewers the wrong impression that that's the type of hardware that they need for something like an rtx 3080 because in reality stepping up from a ryzen 3 3100 to something like the ryzen 9 3950x

Will net you a few frames per second and that's usually it why you may ask well because at 1440p and higher resolutions even the rtx 3080 can become a limiting factor and that nullifies many of the advantages of high-end cpus other cars like the rtx 3070 would see the gap narrow even more but there are some exceptions so i want to dive a bit further into what we saw first of all the 3900 xt and 3950x dominate in productivity apps but the raw number of cores actually works against them in gaming by

Limiting frequencies in lightly threaded workloads that means a more efficient cpu like the ryzen 7 3800 xt can come along bust out some high sustained speeds and offer an equal to or better gaming experience while costing hundreds less the 1700x was a pleasant surprise because optimizations for these first gen ryzen cpus have made them pretty competitive in our benchmarks so with a few minor exemptions you can pop in an rtx 3080 into an older

Amd motherboard and expect frame rates that are within 15 of today's best cpus now that's a cool upgrade story you see most games don't benefit from a massive number of threads but there is a thin red line between enough and not enough processing threads and i think that magic number seems to be four because you know we're starting to see older processors quad-core cpus like this

Ryzen 3 1300x really struggle especially when it comes to in-game smoothness so this should be obvious but i guess i'll say it anyways just don't pair a high-end gpu with a previous gen quad-core cpu because tons of performance will be left on the table but enabling smt on the budget ryzen 3 3rd gen cpus will make a world of difference for amd so if you have a 1300x or 1200 you can confidently upgrade to the 3100 since it offers a low price

And super competitive frame rates even against much more expensive cpus also remember that the upcoming rtx 3070 and more affordable carts from nvidia will create a gpu bottleneck even sooner and therefore need less cpu resources than what you've seen here alright so i just want to wrap up by leveling with you guys don't take this video as a recommendation to just go out and buy a low end cpu and then pair it with an rtx 3080 that's just not an ideal setup but take this video

As a tool to evaluate what your needs are and then hopefully lead you to a better choice when it comes to your next upgrade or your next build so that note thank you so much for watching if you're actually interested in the sort of content especially when it comes to upcoming gpu releases like the rtx 3070 let us know in the comments down below i'm eber with hardware connects thank you so much for watching stay safe spend responsibly my friends and i'll talk to you guys in the next one

Nope ding dongs thank you so much for watching if you're actually interested in this sort of content i give up i give up
