Question about bottlenecks

[limikusz]

Let's say we put a Q6600 with a GTX 970 and we get for example 100fps in Battlefield 4, then we pair it with a GTX 980. Would we get the same performance or slightly higher but not as higher fps as what we would have gotten with an i5?

you get shit with Q6600

Q6600 will get recked in BF 4

My question wasn't that will the Q6600 handle those games, the question was would there be a performance difference with 2 different cards bottlenecked by the same cpu.

at some point no because the CPU could never keep up

yes one CPU will be at 100% and lagging, the other will be at 30% and happy

The CPU is responsible for it's own tasks, as well as preparing and sending information to the CPU.

 

So, let's think about this:

 

You're taking a GPU that will obviously be able to handle more than the CPU can put out at the best of times, and you're comparing it to a GPU that will obviously be able to handle more than the other GPU that could STILL handle more than the CPU.

 

 

In short, no. You're getting bad FPS either way because the CPU can't even do it's own job, let alone do things for the GPU.

 

In a more lengthily debate, it would change depending on architectural differences and efficiency between cards. If a card has more CPU overhead, you'll get worse performance that a card with less CPU overhead if your CPU is the limiting factor. 

 

It's sort of like driving a Tata Nano, and then taking that Tata Nano's 2 stroke motor and putting it in a Lamborghini and driving that around instead.
