What's the performance difference between an a8 7650k and an i3 4160?
What about after I overclock the 7650k?
Is it worth?
>>51238417
yes
>>51238417
The i3 4170 is a better comparison, same clock, lower price.
Not worth it, you need to overclock the 7850k to 4.7ghz to get around 20% performance increase, while the 4170 is around 45% better than the 7850k
>>51238492
What about on a budget? It's $30 cheaper than an i3.
And then there's dx12 multiadapter and better cpu core scaling. With dx12 titles coming out soon it will help the apu perform better?
How does a quad core apu fare against 4 i3 threads?
>>51238417
If your just dealing with a CPU comparison than the i3 is significantly better.
If your also factoring in the GPU then the AMD may be better. Though this only matters if you don't have a dedicated card obviously.
>>51238492
Also, I said 7650k, not 7850k.
A10 just isn't worth it imo, for that price.
>>51238560
Oh are you buying a new CPU, or upgrading from the A8?
Also what are you going to use it for?
>>51238588
New system.
Going to make a cheap steam machine for my tv.
Most games should run fine with the a8.
Also, minecraft and some retro games like total annihilation.
Media center for anime and movies to.
Just a cheap general computer for light gaming, don't want to spwnd too much.
>>51238707
You'd be far better off going with like an Athlon x4 and a dedicated card. Possibly a Pentium Anniversary edition, though they only have two threads so certain games may not even launch(even if it is better than the AMD quads overall).
Perhaps hit up your used market via craigslist or whatever. You don't have to go wild, just get a few cheap key components like the GPU.
If not than the AMD APU is the way to go for gaymen. The extra GPU cores from the A10's can go a long way though. The A8's have 384 cores, and the A10's have 512.
>>51238795
Just to add to that, it's only the A10-7800 or above that have all the GPU shaders unlocked. The A10-7700k only has 384 like the A8's.
>>51238569
Oh yeah, my bad.
I have a 7870k. Let's me play games by itself on low or medium at 1080.
For the love of god just be sure to give it 2400mhz ram.
>>51238560
>>51238707
I really dont think it's worth it, you are going to spend 250$~300$ on an average 7650k build, while a 350$ athlon 860k + 750ti will deliver way better performance. The APU will run LoL at medium-low 60 fps tops.
>And then there's dx12 multiadapter and better cpu core scaling. With dx12 titles coming out soon it will help the apu perform better?
Yes, DX12 takes the load off of the processor, which means all of amd's line is going to fare better at DX12, but bear in mind that newer games will be heavier on the gpu, i don't think a 240 can handle it, you won't notice a difference on games that don't support DX12
>>51239224
Can't find athlon processors here.
And you're right about dx12, but if I pair it with a used hd 7870 or 7950 wouldn't that benefit me more than an i3 would?
The A8 APU scores better in multi-core performance compared to the i3 but not in single-core performance. If your games are not cpu crippled to 1-2 threads then the A8 APU is the better choice.
In terms of iGPU power the A8 shits all over the i3's shitty intel hd garbage.
Overclocking this APU will result in both better multi and single core performance in addition to a faster iGPU. If you plan to OC make sure to get 2133MHz RAM to squeeze the most performance you can from this APU. 2400MHz RAM is a placebo just so you know, the APU can only use a max of 34.1GB/s of bandwidth for the iGPU. Don't forget to use 2 sticks of ram in dual channel config as well, most fuck up this step for some reason.
>>51239300
>if I pair it with a used hd 7870 or 7950 wouldn't that benefit me more than an i3 would?
Yes, but then you'd be throwing away the only good thing about APUs, the iGPU. You'd be better off getting an fx 4350 - 6300 since you already have the gpu. If you are aiming for DX12 even the g3258 sees a huge performance increase.
>>51238417
7650k will be just as fast as 4160 if application can use every thread properly, which often won't happen;
on the other hand, more cores equals better multitasking, something you may want for everyday computer;
4160 mobo will give you better opportunities for futore upgrade;
7650k integrated gpu will outperform hd 4000
also, you need to buy fast ram for APU, something around two 2133 sticks in dual channel
i'd buy apu, even just for better multitasking - but if you think about future upgrades, i3 is definitely better option. also, powerful single-core performance can be something you may want, but you should know whether you want it or not yourself.
>>51239505
But I can use it now and use it better then?
>>51239523
I just want it to sit there, only future upgrade I can think of is adding a gpu.
>>51239600
If you are buying the pc now and the GPU later, then yes, the 7650k is the better option (for very light gaming, nothing else)
>>51239646
Steam games and minecraft?
Probably most demanding game will be planetary annihilation.
>>51239662
>planetary annihilation
That game is poorly optimized, it'll start fine and then gets worse over time.
Minecraft and others similar will run fine
>>51239300
Check eBay. I got a sempron x3 and unlocked the third core for $25 usd
Even though moving up the budget ladder will quickly outclass any APU, you can't beat em where you're comparing builds of the same price class.

Even spending $30 more on a GPU will quickly put every APU's appeal to shame if you can nab a GT 740 however. And it gets much worse the more you spend in the entry level market.
They have appeal within their specific price tiers and nothing more.
