Sorry my APU is a A10 7850K
This is am amazing chip for the price truly. I am able to overclock my APU to 4.7ghz with my Sapphire Toxic R9 280x. The R9 280x is not held back because of the CPU portion of the APU. My Valley Haven Benchmark 4.0 FPS is 50.5 and a score of 1271. My CPU was only overclocked to 4.4ghz at the time and the R9 280x was at 1200mhz gpu and 1700mhz on vram. (Also the test was on extreme 1600x900 with 8xAA)
Intel Fanboys please leave this convo.
Yeah, I just hope the performance gains are going to be worth it, and not just some mere 6-10%.
The fact that the 2015 Carizo processors will be compatible with fm2+ is really awesome feature.
I do hope the next wave of APUs will push the CPU side of the chip up to what an i5 can offer. That's all that it lacks, really. Well, that and level 3 cache. Give users a reason to go with an APU over an FX. Perhaps the next FX processors will be remarketed as APUs, which is why AMD's roadmap shows nothing for the FX series for 2015.
I know what you mean. It is almost obvious that 7850K is the better processor. It was a mind-bender for me, but eventually I decided to (not only save some small amount but also) wait a bit, until the newer (28 nm) technology gets more mature. I would've make the upgrade somewhere in the following year or two, if I could wait for that long.
I would have personally gone with the 7850K, but that's me.
Yes, now I know it works first hand. Performance is not that bad either. Since I don't play games, the memory speed (and the absence of graphic card(s)) doesn't affect me much. And since I've upgraded MoBo + APU ( + SSD disk for the Linux), the system feels much faster than the 6-7 year older counter-part.
It will, but its performance will be affected.
Wait! What? So the 6800K won't work with my old DDR3 1333MHz?
This is interesting, and a pretty close call on the face of it, but there is no price information shown, which is a pity. It makes a difference. At PCcasegear.com we see today AU$175 for the 6800K and AU$219 for the 7850K. The difference was greater when we were building, and it was a major issue, since we had a $620 total budget. Used but still shiny case/keyboard/mouse/etc at the popular price helped, of course. So the APU graphics performance was critical to success for this gaming machine - a Linux Steam box, in effect. These APUs are -highly- dependant on RAM speed, since the CPU RAM is also the VRAM. The bonus is that the CPU part can benefit from this, but still many pre-built systems have DDR3-1600 included, which is just too slow. There was a small price increase for 2133, of course, but it _IS_ worth it. Think a lot of A10 benchmarks are skewed to the slow end because of this. We spent our money on maxing out the RAM speed, and it has paid off bigtime. Long term, the modest GPU part of the APU may well need to be supplemented by an external PCI card, we recognise this. But the 6800K CPU part can then be overclocked a good bit further than the 7850K - especially with a budget water cooler. So I voted for the 6800K, and we are happy with the choice. With its small, cheap SSD it boots to login in 6 seconds, and full desktop (after password entry) is so fast as to be hard to measure, but less than a second. If you doubt this (and we did, even though it was in front of us) do try Bodhi Linux 2.4 on an SSD. Scary fast, even with the bling turned on. In summary, the lower price and higher overclock on the 6800K was the deciding factor for this project, but you need the fast RAM for that to work.
