fx8320 to 4770k ? - Page 3

post #21 of 36
I'd save some money and look for a (obviously used) nicely binned 3770k. Sure, IPC isn't as good as a 4770k, but a 3770k that OC's nicely will beat out the heat-trapped 4770k.

well first thing is.... you have MANTLE which help a lot your CPU and much more on CF 290

second is, going from a FX8320 to a 4770k will give you a good perfomance increase but not by much on average and high FPS but in minumun FPS will be higher with the 4770K

me being you... i will use mantle if you play BF4 until Intel brings to the table the new Haswell-E or Haswell .

The 8320 is a pretty damn good CPU. As for upgrading being worth it, I would say it depends entirely on what you want to get out of your PC.

If you want to game you'll almost be guaranteed a higher FPS (assuming no GPU bottleneck) going with the 4770K, but if you use the computer to render things, encode, or well multi-threaded stuff, then I would wait for a more significant improvement before buying a new CPU/MOBO. Maybe 1-2 generations past this.

Assuming Haswell-E is going to be the same as a 6-core version of the Haswell i7, expect the same performance increase you'd see from Sandy to Sandy-E. If you're gaming, it won't be noticed. If you're encoding videos expect a reliable 50% boost from the quads, and in that case it would most likely be worth an upgrade from the 8320 if it's not too much for your budget.

The importance of a CPU can only rise with a higher resolution, it never become less important.
Resolution is almost 100% bound to the GPU performance, with the exception of UI elements and some other insignificant things. The CPU is always very important, even if you're gaming at 800x600.

It doesn't matter if you run the game at 16M x 9M resolution or 1920 x 1080 resolution, if the scene itself has the same complexity, the CPU load will usually not change a bit. 3D Meshes are scalable, so all the CPU has to do is really load the mesh to the GPU, and from there it does it's own thing.

For sure will be 4 coar HT. Anyways, Haswell-E or when AMD pulls out a new high end offering your best bet!

There will be no 4-core haswell-E CPUs.

6 and 8 core only.

I don't think you understand how the CPU and GPU scale and work with loads. If a CPU can handle a scene just fine, then that's that; the CPU can handle it fine. If you're getting 100 FPS in a game with 1920x1080, and your performance degrades to 35 FPS under 4K, that is a GPU limitation; upgrading your processor is not going to help you. Scenes that are graphically intensive are almost always GPU limited.

Playing a game on 800x600 removes all stress off a GPU, and the latency of the system becomes CPU, not the GPU.

I do, very well.

Going from 1920x1080 down to 800x600 doesn't magically put the CPU under a bigger load, it's still sending the same scene data to the GPU. The GPU load is smaller, and the CPU load can slightly decrease depending on certain things.

Regardless of what resolution you play at, the CPU is for the most part equally important.
If your goal is to play at 4K then yes you're going to need a good graphics card, too.

That all depends on what you consider graphically intensive.
Shadows, Lighting, Anti-Aliasing and Anisotropic Filtering are all usually 100% GPU bound, but the amount of characters on screen adds complexity to the scene, yet uses a lot of CPU resources.

Which was exactly what was stated, and reinforces my position, not yours...

No it's not. You can get away with a weak CPU and a strong GPU more easily than a weak GPU and a strong CPU. The CPU in my laptop is great. I even have a discrete AMD Radeon chip for my graphics, and I can't get very far with gaming at all because the CPU does not make up for the lack of any real graphical horsepower. This is common knowledge and a common trend in the enthusiast community; people going balls to the walls with their graphics and leaving their CPU's respectable, but not $600 Intel Extreme's anymore.

Dude...if your CPU can handle the complexity of the scene at 800x600, or 1920x1080, 4K makes no difference. As long as you're taking into account physics and particles, the data is already being processed at the same speed...the crutch is how fast the GPU can show it too you.
