So, i'm very interested in the "AMD Athlon II X4 651". It's the a8 3850 (or) a8 3870k with the IGP deactivated. (not sure which one, since the a8 3870k is 3gz, same as the 651).
Being the 960t as the same price of 651, here are the stats.
both priced at 111usd
Athlon II X4 651
1866 memory controller
huge l2 cache at 1mb per core, 4mb of l2 cache in total. Though, it has no l3 cache
Phenom ii x4 960t
1333 memory controller
only 512kb l2 cache per core but has 6mb l3 of shared cache
So, i'm just wondering if anyone has the 651, i'm REALLY interested in the benchmarks and how far people have OCd it.
I've also heard rumors of the 651 OCing at around 4.3-4.5 on air, seeing as it's 32nm, lower heat because the IGP is deactivated, so that leaves more room for OCing etc.
I haven't seen any benches of the 651, but you can compare the A8 3850 to a phenom ii to get a good idea of the performance. http://www.anandtech.com/bench/Product/399?vs=88
From all the benchmarks I've seen on llanos, they look to be basically even with a phenom ii at the same clocks. Phenom iis seem to get a little bit better performance in games though (a few fps).
I'd say that the only major differences between the two is the choice of motherboards, and that the 960t will be easier to overclock. Also, with the 960 you have a shot at unlocking extra cores.
Overclocking on llano depends a lot on the motherboard, 4.3-4.5 is possible but I wouldn't believe it till I see it.
Yeah, I understand I can compare the a8 3850 directly to the 960. But, With the igp deactivated, you can safely overclock it even higher, because there is less heat and power consumption. That's what i'm thinking, anyways.
I'm just wondering if i can find someone with a 651 to see their results with overclocking the chip.
Not even close in my opinion, there are several reasons to go with the Phenom. The Phenom is significantly better at gaming, and FM1 motherboards are generally not made for hardcore gaming, thus will have much less options than a FM3/FM3+ MB. Also the Multiplier is locked an the Athlon so 4ghz is out of the question, tops is probably about 3.4 ghz.
I did a little digging and it seems that overclocks above 4Ghz on llano are coming from MSI boards that have a "lab burst mode" that messes with the system clock to give artificially inflated results. There's some discussion about it at extreme systems. http://www.xtremesystems.org/forums/showthread.php?2740...
edit: based on reported OC's on llano 3.3-3.6Ghz is typical, results vary depending on the motherboard used.
