It's literally 4 generations old at this point, and while the incremental gains haven't been much, they do add up.
This means Skylake should be quite a bit faster than a Sandy Bridge in gaming and much faster than Vishera, i.e. http://www.anandtech.com/bench/product/697?vs=1543
You can see Skylake is twice as fast as Vishera in most benchmarks and has almost double single-thread IPC in Cinebench. Gaming, generally a Skylake i3 gets more fps than a FX 8 core because again, single thread.
So, I would urge the OP to start seriously considering Intel and not get too excited over Zen, I can say that (if my opinion matters to you) I have absolutely zero confidence in Zen although I want it to be a success. If the rumors are true and the desktop chips have a high core count (8) and SMT, so we get an 8 core 16 thread chip, then most likely the IPC will be low and it will get less fps in games than a 4 core i5. This would be a repeat of the same strategy/approach that Bulldozer tried and failed at, i.e. more cores at lower performance. Personally, I'm not holding my breath, although I could be wrong. There's other factors to consider in a gaming CPU too, like the speed of the cache, the speed of the memory controller and so forth. In my testing my DDR3 runs nearly twice as fast on my i7 than it did on my FX-8350. The L1 cache is over 5 times faster. The L3 cache is significantly faster and not just tacked on and useless.
Anyway, I hope this helps add something.
I will explain the reasoning behind my post. If you read the title and the original post, you will see that the points the OP makes are:
- He already has available one of the best overclocking AM3+ motherboards and an 8320, that currently runs at stock.
- The GPU is R7 270 (not what you 'd call an ideal GPU for 1080p gaming).
- He wants to hear something else than "start over (and get Intel).
- He's on a budget.
My immediate thought, was "put the 8320 on the Sabertooth instead of that 4+1 Gigabyte and overclock. Use any available money for bettter GPU". The reference to 2500K was to show that if someone still plays rather happily with Sandybridge, he should be able to do so too in an FX @ 4.4. Assuming a game where an Intel Sandy keeps barely 60 fps, a 10% deficit for the FX would mean 54 fps. Let's round it down to 50 fps. Big deal... It's still perfectly playable.
I doubt his father passes his day running benchmarks or is affected by benchmarkitis like most of OCN members, so as long as he can play, i don't think he will be thinking "ooooh, what if i had Skylake!".
Here are also some recent opinions of i5 users (i5 4670k )
Former FX user went Skylake and now back to FX:
So, at the end, his dad can play and the only thing he should possibly buy, is a new GPU. I think the solution fits the requirements of the OP.
As for Zen, i also don't expect Zen to run on most current and past games better than a Skylake, because once more, the IPC will be inferior and more cores are of no help if the program doesn't use them. Zen will be great for people who do video encoding like me. But, it will still provide pleny of power to play with ease and if the price is right, that's what AMD was always doing. People who can't live or enjoy something unless they know that they have "the best", will still buy Intel. But you don't always need the best to get the job done. Zen will shine more in future games that will become more heavy and multithreaded. At some point it will beat quad Skylakes. But for the immediate future, it will lag a bit behind, i think.
If at some point in the future, an overclock of 4.4-4.5 isn't enough, nothing forbids his dad to get a whole new system and by then it will be better than any current Skylake. Why waste these AMD parts, when all FX CPUs are unlocked and thus he can get free upgrade without spending any new money on CPU, mobo and RAM (which he 'd need for Skylake). Basically, with the Sabertooth, he can get EASILY a 1Ghz overlock over the stock clock of the 8320, so why not try that before wasting money?Edited by Undervolter - 7/7/16 at 4:46am
