PUBG CPU Core Benchmarks – How Many Cores Do You Need

Last month, PLAYERUNKNOWNN’S BATTLEGROUNDS (PUBG) released a patch with optimizations that improved performance for those running a CPU with six or more CPU cores in their gaming rigs. PUBG uses Unreal Engine 4, which is capable of producing solid image quality, but can be rather taxing on your PC hardware. This Early Access game developed by Bluehole, Inc. has already sold over 11 million copies and recently passed up Dota 2’s record of 1.29 million concurrent players with over 1.34 million concurrent players last weekend.

PUBG Breaks 11 Million Owners

Those numbers are insane and that means there are nearly 11.5 million PC gamers out there looking for a chicken dinner. To get the best performance from PUBG you need a solid graphics card and processor. There are dozens of sites that have benchmark results for video cards, but when you look for CPU numbers there are just a handful. We were curious how many CPU cores you needed for PUBG and couldn’t find any results that showed benchmarks on the same processor with different core configurations.

So, we fired up our Intel X299 test platform with the Intel Core i9-7900X 10-core, 20-thread processor along with the NVIDIA GeForce GTX 1080 Ti Founders Edition graphics card to see how different core configurations would impact the framerate in PUBG. We ran the DDR4 memory at 3600MHz, but left all the other UEFI settings on our ASUS X299-Deluxe motherboard ($469.62 shipped) stock. We planed on testing 1-core, 2-core, 4-core, 6-core, 8-core and 10-core performance, but we got a memory error when trying to run PUBG with just a single-core.  The minimum system requirements for PUBG show you need a dual-core processor, so this makes sense. Here’s what you need to run PUBG on your PC, according to developer Bluehole:

OS: 64-bit Windows 7, Windows 8.1, Windows 10 (recommended: Windows 10)
Processor: Intel Core i3-4340 / AMD FX-6300 (recommended: AMD Ryzen 5-1600 / Intel Core i5-7600K)
Memory: 6 GB RAM (recommended: 8GB)
Graphics: Nvidia GeForce GTX 660 2GB / AMD Radeon HD 7850 2GB (recommended: GeForce GTX 1060 or better)
DirectX: Version 11
Network: Broadband Internet connection
Storage: 30 GB available space

PUBG Test Settings

We set the image quality to the medium preset for testing on the NVIDIA GeForce GTX 1080 Ti (around $749 due to miners) and used FRAPS to benchmark PUBG. This is extremely tough as you have to benchmark with the same weather effect and spot in a game that can have up to 99 players at a time. It took some time, but we managed to get several runs in an outdoor environment on each setting with no people around. This area is a little easier than some, but it worked to show CPU differences. We averaged the results from the multiple at 1080P and 1440P display settings and charted the average frame rate below.

PUBG CPU Core Performance Benchmark Results

The Intel Core i9-7900X is a $962.89 shipped 10-core, 20-thread processor that is overkill for PUBG, but we used it and disabled active cores to simulate different core counts. In stock form we were getting around 143 FPS at 1920×1080 and 142 at 2560×1440. If we disabled Intel Hyper-Threading this remained the case at 8-cores and 6-cores, but once we hit 4-cores (quad-core) performance dropped down to 117 FPS at 1080P and 110 FPS at 1440P. If we went down to 2-cores (dual-core) the performance dropped down to 89 FPS at 1080P and 86 FPS at 1440P. Enabling Intel Hyper-Threading technology on the dual-core processor got performance roughly on par with a true quad-core part and the quad-core part with Intel Hyper-Threading was right there with the 6-core and above parts. So, to get the most from PUBG with a GeForce GTX 1080 Ti you’ll want to be running a true quad-core processor with threading enabled.

pubg 1080p core performance

This chart uses the same data as the previous one, but better illustrates the difference between a dual-core, quad-core and hex-core processors. We saw around a 31% performance jump by going from 2-cores to 4-cores and then another 21% performance jump going from 4-cores to 6-cores. These are solid results and useful to know. If you are gaming on an older platform that uses a dual-core processor with or without Hyper-Threading or a quad-core processor without Hyper-Threading this might give you an excuse to upgrade. Intel 8th Gen Core processors (Coffee Lake) come out next month and will bring six-core desktop CPUs into the mainstream for both the Core i5 and Core i7 series. AMD already has 6-core or more parts in the Ryzen 5 and Ryzen 7 series series, so both AMD and Intel are ready for 6-cores to become the norm.

    Good benchmark article that could be made even better if you took FPS averages across real games, not static unpopulated areas. I say this because I feel the 7900X performance drop is much greater than ring-bus chips (7700K or even lower) only when the action starts getting hot-n-heavy, making it statistically significant. I bought this chip because on paper it looks just a bit behind the 7700K with the benefits of single-PC streaming, but in practice, the 7700K can average around 90-100FPS whereas I’m only getting around 70FPS on average. This mesh is just not well suited for gaming, but still cool to see where/how it’s happening.

    Great test! Although did you remove the fps cap in engine.ini? These numbers seem to be bumping up against the stock 144 FPS limit. And to do a true CPU test, please set resolution to 1920×1080 and set all in-game graphics to low. 😉

    This is awesome

    Can you compare pubg frames with different Gen i5s/i7s with a constant gpu? (970/1070))

    • legitreviews

      what processors are you interested in seeing?

      • Real #OGNinja Ogami Itto

        Ivy Bridge i5&i7 vs haswell i5&i7 vs kabylake i5&i7 and maybe a haswell-e chip in there too for the 6 cores

      • phinn

        Would love to see 6600K vs. 7600K vs. 8600K.

  • CarpetHead

    PUBG has a 144fps cap, so it seems pretty clear why you don’t see any improvement after reaching those framerates. The data is invalid

    • Ottoore

      Great testing without removing Fps cap!

      • Nathan Kirsch

        Live and learn guys! I’ll try to update with the latest game build this weekend. I get it, but also know that not everyone is going into the Engine.ini file in the hidden AppData file and removing the cap.

        • Ed

          There was a thread floating around on Steam that PUBG was banning people that alter the engine.ini file…any truth to that ?

        • Chay Meredith

          Wheres the update with the cap off?

    • sir

      you can remove the FPS cap if you want to, default is set to 144fps

    Common utility that relies on multi-core CPU is file compression. Open-source & popular program is “7z”. This has very many derived applications based on it as well. On my Intel-7, I run it with 6 of the 8 cores selected. Perhaps you could test this as well, so that readers like myself can compare our results to yours.

    The application works better than similar applications. It is regularly updated, and compresses faster & better than most others, especially the commercial popular product using the RAR format. Best compressions work also by have large & fast memory space available as well.

    Great insights, Sir!
    It would be great to have screen shots of the logical CPUs utilisation graphs of the task manager in each of the above cases, to show what kind of cpu load percentages are we looking at (overall and per core)…
    I have heard games (like FIFA 17 at 1080p and 4k) maxing out dual core cpu (95-100% usage) whereas i7 6700 showing ~50% across most cores… Would prefer to observe the loads on more than 8 threads though…
