Does 8 cores matter?

I'm having a tough time deciding on my new processor. I'm brand loyal to AMD so no Intel crap. So my choice is between the 4 core AMD FX 4350 or the 8 core AMD FX 8350 Any suggestions?
 
Get the 8350, its actually a Quad Core chip, while the 4350 is a Dual Core. I wont get into the technicality of it, you can do some googleling if you dont believe me.

The 8350 is by far a better choice and a good investment if you're into AMD and I respect that, I sure someone will ask why or try to convince u to get a Ivy or haswell chip but I wont get into that. Hope that helps
 
The only consumer 8 core exists purely in AMDs marketing department.

The FX series is a shot at hyperthreading and in theory a good one. It was a disaster to start with. Not sure if its shaped up yet.

AMD is betting on GPUs as FPUs and once again in theory the best option. However it will still be a couple more years before its that commonly utilized by run of the mill software. So halving your FPU count is stupid.

Lastly one instruction set decoder for every 2 cores is a performance issue. An 8 core CPU has 8 front ends and 8 FPUs. I7s have 4 amd "8 cores" have 4.

For a gamer do you need it no. But if your going AMD I would get their 8 core. Plenty of things can use the extra threading however.

The second generation eight core is better. I have one and it runs fine for me.

Too bad the has been is AMD right? If you were a fan of the Athlon series and Phenom that became of it that is NOT the same company that as AMD today. The employees the leadership and a lot of the investors are gone.

But here is why I would choose the 8 core AMD if going AMD. The "quad" core amd is a competitor to the i3. It has 2 front ends and 2 FPUs. In a 4 thread situation AMDs front ends can actually operate the shared cores simultaneously by halving capacity. Instead of the i5s 4 instructions per clock cycle per thread. With AMD its 2 instructions per clock cycle per thread for 4 threads or 4 per 2 threads. The next bottleneck is the FPUs. Floating point math (anything not whole numbers) is done on the FPU. In gaming this is the physics calculations. On the AMD quad we can only have 2 cores simultaneously doing floating point math. Its AMDs intention this math take place on the integrated or dedicated GPU instead. But under many current realities the Intel is ahead in FPU math.

So by going the 8 core model route you have the same instruction set decoding rating and FPU count as both the i5 and i7. AMD quad against i3 Amd hexacore against i5 and 8 core versus i7 that's pretty much the pecking order.

On a good day when FPU math is shifted to GPGPU AMDs design should outperform Intel. On a bad day its hyperthreading at best.

The 8350 should be great for any game out there. The only one I can mention it will suck on is the one every CPU on the planet hates. Metro 2033.
