Stop it. All these predictions have no meaning... first we need to wait for something "more real" ..

Well, if you only play the latest AAA console ports, preferably with DX12, then you might not need high IPC...

That would be Battlefront and no,in that game FX octos compete with haswell i7s fine. Although I do not disagree with you, Skylake is a much newer architecture and 2012 PDs can't compete with that in non GPU bound games.

overreact much ?

games do need some cores, just not really 8c/16t right now

4c/8t or maybe 6c/12t with high clocks (4500+) and high IPC is the best

We've gotten to the point where the multithreaded performance of FX is very similar to the multithreaded performance of quad core i5's.

quad core skylake i5 actually beats Piledriver FX for x264 encoding which scales practically linearly with core count at this point.

i5 wins by a mile on everything that's not quite highly parallel by default, i3 often wins when they're not.

The most efficiently multithreaded games and engines show piledriver getting beaten by i5 and walked all over by faster CPU's.



I don't know what world you're living in, but it's nothing like mine

 

Your poor, cherry picked game just got discredited.

Calling FX trash is certainly an exaggeration. Especially considering the price.

I am not saying the BD uArch is a success, it's a failure of both hardware and software as developers are just lazy and have refused to properly thread their software. Saying that, I do hope that Zen can at least match IB or even Haswell's IPS (IPC in itself is meaningless) so that we get advancement in CPU architecture. We've been stuck in this paradigm for too long and it's time we shifted.

You are not running multi threaded high volume scientific calculations on your home desktop. The most "multi threaded" software you are running, is your web browser, when you open several tabs.

Game engines are still more single core focused, even when they can run stuff parallel. Which means single core IPC is still important than 32 cores.
If you have to run 32 cores but reduce their IPC and clocks in order to keep it under check of TDP/heat, you will not get as good performance as a 8/16 or 4/8 which can have higher IPC and higher clocks.
It is also more problematic to OC a 32 core than a 2/4/8 core chips.

Once more next gen game engines comes out, and more parallel computation between a GPU and a CPU come out, we can talk about 32 core CPUs for the desktop.

Also, no, FX do not match i7 because of cores. They are slightly ok in most because of the higher clock speeds at stock (like the 9590 at 4.7ghz) which is only matching an i5 from 3-4 years ago (sometimes less than I3, regardless of cores).

Also, IPC vs IPS, IPC is not meaningless in any way. It only shows that you don't really understand how CPU works.
It falls on overall design. Each design has its own advantages and disadvantages.
A 32 core with low IPC and low clock speeds can have the same IPS as a 4 core CPU with high IPC and high clock speeds, but if you run a program which requires less cores and runs higher short calculations per thread, a high IPC/high core combo will be far, far better than 32 cores with low IPC. This is why in games, you can easily see skylake cpus equaling broadwell-e in games, while FX cpus are barely keeping up.

One last thing:
The FX 9590 has more MIPS than the 4770k (if you look at the 7-zip tests which are measuring MIPS, AMD state 28K for the 9590 vs 21K for the 4770k that 7-zip performance state). Yet the 4770k runs better in almost every test. Which overall means, IPS isn't the do all die all importance.

Well a 220W CPU running at almost max OC at stock, cost the same as a i5 6500, which is faster in a most cases , uses DDR4, and doesn't require high quality cooler, and with a bit extra you can get the K version which can be greatly OCed to give very high increase in performance.

The same be be said on the low end, with the only exceptions are the APUs, and that is if you take the internal GPU into account. If you are using a dGPU, well, those CPUs aren't up to par with similar priced intel CPUs.

So if we are being honest, the FX is a dead tech. It is pointless to buy it even 2-3 years ago.
Hopefully zen brings it back up to par.

I totally agree on the FX-9xxx chips being an absolute ripoff.
But you can get a FX-8320 for about $130 and that is essentially the same chip as the FX-9xxx ones. You'll just have to oc it yourself.

Only in very rare cases I'd prefer an i3 over an 8320 and i5 chips are already more expensive than $130. So at the low end I still consider FX a viable purchase for gaming. If one can/wants to spend more and get an i5 then that is certainly the better choice, I agree.


All in all I too, just like every sane person, hope Zen can bring back competition to the mid to higher end gaming CPU market with adequate IPC, so that I actually have a choice for my next CPU purchase tongue.gif
