Quad core AMD A8 = 2 cars max?

Ok ok. So I have a custom gaming pc,with an AMD quad core cpu, but the framerate drops with 2 cars?

specs: AMD A8 7600 quad core

ASUS STRIX GTX 960 (the new one)

8GB KINGSTON HYPERX DDR3 RAM

STOCK AMD COOLER

CORSAIR 750WATT PSU

Thanks, 'cause I thought 4 cores would be able to run 2 cars.

 

you processor is probably a huge bottle neck. you should get a fx 6 or 8 core tobrun this game properly. i have an amd fx 8350 8 core and the game run smoothly with 4 cars or even more(depends on the detail)

 

AMD cores are usually weaker than a comparable Intel core.... therefore you need a higher clock rate and/or more cores.
And if you're looking to run large maps, upgrade to 16 GB

 

That CPU is not great at all anymore. Plus, BeamNG requires fast single-core performance to work well. You could have a 12 core and a slow single-core performance and the game won't run any better.

 

Its also only a processor with 2 floating point units, a major bottleneck for going beyond 2 cars in BeamNG

 

Hey, the first thing you should do in any case, is to get a proper PC hardware monitoring tool, such as AIDA64. Run it along the game and monitor your resource usage (CPU cores usage, GPU usage, RAM usage ..etc).

Then you see where the bottleneck is in your PC, but from experience ... AMD CPUs don't work well in BeamNG, because BeamNG seem to be running 1 vehicle per 1 core, AMD has no hyperthreading (yet) and that's why it lags real bad.
I had AMD 8 core FX8350 @ 4.4ghz and I got 15fps with Gavril T-series truck. Now i have i7-6700k and i get 60fps even with 8 - 10 vehicles.

Reason for that, is because AMD's 1 core = 1 thread, while Intel CPUs have hyperthreading and 1 core = 2 threads.
So AMD 1 core @ 4.4ghz = 4.4ghz total computer power
Intel's 1 core @ 4.2ghz = 8.4ghz total compute power
So that's why intel CPUs run BeamNG better, also intel's architecture is better and more optimized.

So it's not about 4 cores or 100 cores, it's simply because AMD has no hyperthreading. even if you have 100 core AMD, you'd still be lagging, even tho my old FX8350 could run any other game in ultra just fine (apart from DayZ that also runs off of single core).
Hope this explains why AMD CPUs lag so much.

 

That CPU is really old and not very good. I hope you didnt pay more than 600 USD for the PC

 

The lack of CPU power and lack of RAM memory are seriously bottlenecking your GPU, you should seriously consider upgrading.
And as @Sethioz and @1UZ-FE said, your CPU´s quad cores can´t be compared in performance to Intel's Quads.

 

Are you sure that's how things work?

 

It looks like someone needs to learn a little more about computers before trying to help someone else.

 

Umm. No. Your explanation is entirely false.

While you are correct that AMD does not have hyperthreading technology (as it is licensed by Intel), nor does it have any anything like it (go watch the TechQuickie video about hyperthreading to know how it works), this has nothing to do with why AMD CPUs run BeamNG poorly. The Intel Core i5-6600K will match the Core i7-6700K in performance in BeamNG up to about 4-5 vehicles. And the Core i5 does not have hyperthreading.

This is not how clock speeds work. Each core runs at a certain clock speed, with the possibility that different cores run at different speeds. Hyperthreading doesn't change this. Neither hyperthreading nor the number of cores a CPU has effect the clock speed that individual CPU cores can run at. And each core has its own thread (or two when hyperthreading), which means you can't determine raw single-threaded performance based on the number of cores/threads.

This is the only part of your explanation that is remotely true. However, to say that it is optimized is to imply that it is optimized for a certain thing, which it isn't. Intel CPUs are better because they do more calculations per clock cycle, therefore, can do many more calculations per second at the same clock speed. And BeamNG uses time to work out physics. So, more calculations per second means more physics can be calculated per second.

Core count is irrelevant as long as you have at least 2, with 4 being recommended, until you start using a significant number of vehicles in BeamNG.

Sure, any GPU bound game. But CPU bound games, such as BeamNG.drive, Cities: Skylines, Parkitect, and Planet Coaster, it falls flat on its face, because it isn't a very good CPU, even in heavily multi-threaded workloads.

 

Ok thanks guys!
