Will a 3960X bottleneck a next gen GPU?

12 minutes ago, Enderman said:

What do you not understand about "it's the same architecture"?

It is the same CPU as the 2600K with 2 cores 4 threads more and a higher TDP.

 

Maybe you weren't aware of this, but extreme edition CPUs have a model number that is 1000 above the consumer generation, despite having the exact same architecture.

A 3960X is not from the 3770K generation, it is from the 2600K generation.

 

This means that the single core performance is the same, and since very few games can use more than 8 threads, the gaming performance is practically identical.

Same with certain rendering programs which don't use many threads, such as adobe.

 

I guess you just weren't around back when these CPUs were just released?

Ok, I found some benchmarks on the 3DMark database.

https://www.3dmark.com/fs/13263681

This is a person with a stock 1080ti and stock 3960x running firestrike 1.1. They get a score of about 22000.

This is a person with a stock 1080ti and stock 7700k running firestrike 1.1. They get a score of about 23000.

 

Need I say much more?

I have to say, I'm a little offended you think I'm that stupid.

 

Maybe you weren't aware of this, but you can't estimate performance of  two CPUs with a different core count and different platform entirely but the same architecture, ESPECIALLY if you are going to include a multithreaded program like adobe premiere. Adobe Premiere (cs6 and later) will make proper use of about 32 threads, and not much beyond that. And no, single core performance is not the same. You CANNOT simply make an assumption that the 3960X will have the same performance in games at 2600k. It might, and at this point I'm less concerned about the fact that the 3960X is not as good as I thought, but more of the fact that your logic is completely flawed. 

I don't think you understand how single thread performance works...

If it's the same generation and same clock speed, then the single core performance is almost identical.

Yeah the two extra cores make a bit of a difference in certain games, but the majority of games do not use more than 8 threads so there is no improvement there.

 

Why do you think that nobody recommends the 6950X or other i9 extreme edition CPUs for gaming?

 

I think you might want to do some research on how single thread performance affects gaming.

Artificial benchmarks, unlike most games, can often take advantage of more than 8 cores.

Also, firestrike is a GPU heavy benchmark, so of course the two systems will perform similarly with the same GPU.

Again, go read what I said in my first post about the type of bottlenecking.

Not only that, but the 8700k has better single core AND multithreaded performance with 4 extra threads than the 7700k.

The points remains though that the 3960X will not bottleneck a 1080ti, not really even in the sense that you said. OP should not upgrade his X79 system, he should really keep it for a little longer, it's stupid to upgrade to a 7700k or 8700k right now.

 

EDIT: You also mentioned in your original post with benchmarks a multithreaded program, adobe premiere. You're now shifting the topic about single threaded. Including benchmarks in adobe premiere for the 2600k only and not the 3960x doesn't make any sense, and as you can see in the Cinebench benchmarks you just posted, there is a multithreaded difference between the 2600k and 3960x.

Wow, it's almost as if you didn't even read my first post.

Maybe let's try again:

 

Well, "bottlenecking" as in you could be getting more performance with a better CPU.

Not "bottlenecking" as in you won't see a performance difference with a better GPU.

 

Most people don't understand that both the CPU and the GPU contribute to the final performance.

 

 

Your firestrike benchmark pretty much proved what I am saying, although the difference in real games will be more because they rely more on single thread performance and aren't just a GPU test.

Fair enough. I still think that @LapX should not upgrade his system right now. He will still get a very good gaming experience with the 3960X and 1080ti, especially at higher resolutions.

 

Have a nice day.
