Is the new Kaveri A10 7850K perform better or worse than the Vishera FX 6300?

I am talking about just the CPU power, since almost all of us know that the AMD might/will not make anymore discrete CPU and will focus on APUs (integrated graphics and such).

How does Kaveri A10 7850k go off against Vishera FX6300 discussing purely the CPU capabilities of each chip.

say I won't be overclocking, will Kaveri stand its ground? And does the A-Series have true-cores instead of "core" modules by Vishera?

no even at stock clock speed the apu is far behind vishera is much more powerful and it does have 6 true core only the level 3 cache is shared in pair of cores, that wont change anything, do not beleive everything you read on the net about these chips ppl love to hate them (they are called intel fanboys) these cpu performs really really well for much better price..

Kaveri will not stand its ground. The base design is the same, Kaveri is just an updated version. The lack of L3 cache is what hurts Kaveri's performance, and other APU's for that matter. They are the mainstream line. FX is still the high end desktop line from AMD.

If your going for a ATX build for cheap get the 6300, if you want a micro ATX or Mini ITX build go 7850k, they preform about the same. There wont be a noticable difference on either side. Just chose based on preference.

Side note: AM3+ is rather old and will be replaced by AM4 for AMDs "extreme CPUs" (if any) ,and fm2+ is new and will be around for another APU generation or 2.

1. Stock for stock the fx6300 is still better and has more brute power. It also overclocks better and then is really the better option. Cons the fx6300 is on a outdated AM3+ socket but it still has some life left in it. The APU may be on a new socket but they are not high end and are not suited for enthusiast gaming like AM3+ and FX processors were and still are. Plus the new APUs are way overpriced for the performance you get weather its used as a CPU or APU. The a10 7850k being new has some newer intruction sets and slightly better single core/sigle thread performance but still falls short. Mantle won't be helping the APUs much either. With the announcement of dx12 Mantle will be lucky to see the light of 2015. HSA is also just another bs selling point, it is more pre conceived than mantle and probably wont see real support for 2-3 years.

2. The fx6300 does not have 6 cores. It has 3 modules with 2 threads per module or 6 threads. The a10 7850k has 2 modules with 2 threads per module its not a true quad core just a dual module with 4 threads.

3. AMD announced back in 2012 on their own forum they would no longer be competing with Intel in the enthusiast cpu market. So unless they have changed their mind the am3+ socket and fx series processors will be the last of AMD enthusiast processors. So probaby no AM4, but just more APUs.

If your willing to spend the $180 for the a10 7850k dont save some coin and get the fx8320 $160 and a Asus M5A99FX PRO R2.0 mobo.

I run a fx6300@4.8ghz 1.45v, fx liquid cooler, asus crosshair formula mobo, powercolor 270x devil@1250/5900 1.206v. For what I spent I am very pleased with this build especially since I've been able to get the fx6300 stable @ 5.1ghz 1.575v just for fun. Next build will be Intel/Nvidia though.

yeah but how much would an equall a88x mobo cost? less

This is not true. The FX6300 is 6 real cores. The FX arch is built around modules, yes. These modules are designed around two integer cores sharing a single FPU, and also sharing L3 cache. So the FX6300 is 6 integer cores and 3 FPUs (placed amongst 3 modules).

Refer to this design diagram for reference:
http://en.wikipedia.org/wiki/File:AMD_Bulldozer_block_diagram_%288_core_CPU%29.PNG

AMD did a very poor job of explaining their own arch because people still equate the FX line to using something like hyperthreading (logical cores)....

This is so far from the truth. The IPC of Kaveri clock for clock is slightly better than the 6300 or any other Vishera cpu. Lack of L3 is not a big deal because the cache latency in the Vishera chips. What hurts is only having two modules/ four cores.

kaveri APU's are nice for people on low budget that want a PC to surf the net and play daily light games, but for heavy gamers a high-end FX chip is required...also it is true that the lack of L3 cache kills the performance for gaming, this is the reason why the FX is way more powerfull than keveri apu's...if it was only about the number of modules, then the kaveri four cores would stand his ground against the FX-4300 CPU's...but clearly it's not... at least when in comes to gaming.

Per core performance of the 7850 is slightly higher then than the 4300. The 4300 clocks slightly higher. L3 cache is the only advantage of the 4300. It's widely known that the FX processors have a big problem with L3 cache latency. So I stand by my statement the only advantage FX processors have is the higher core count. That being said, for pure value I think a stout 970 or 990 board, a 6300 and discrete card is hard to beat for value. I have an A10 5800K, a 6300, an 8320 a 965 BE, 1070T, 960T unlocked to a 1605T. But going forward it will be all FM2+ for me.

Alright if you could provide any gaming benchmarks where the APU is doing as good as the 4300 CPU i will believe it...but i doubt you will because L3 cache is the most important thing for gaming, this is the reason why the FX-83xx does so well ingames is that they have a big 16mb L3 cache pool..
