[FUD] Meet AMD’s new FX 8320, 8300 eight-cores - Page 6

post #51 of 92
Hm, interesting.

I'm not holding my breath though, but it's always nice to see what can I expect from AMD, and given the time arrives when I see fit, replace my X6.

For the same amount of transistors being active.
1000 transistors @ 5 GHz will still use less power than 1 000 000 transistors @500MHz wink.gif

As long as all the poop goes down it should be fine; you would be maximizing the capacity of the flush.

I don't really care tbh that's why im not looking it up) so yeah that's why it sucks in gaming esp with light threaded games. if you guys can find a way to use 1 whole module(2 integer cores) on 1 thread then id jump on the bandwagon and say it's a quad core which is impossible if you actually know anything on how software works rolleyes.gif
Of course its a 8 core, it has 8 integer cores. Tho the idea behind the architecture was to create their own "hyperthreading". In which AMD blew Intel's hyperthreading out of the water just by simply adding four more integer cores to equal them 4 extra threads. Anyhow this means it can handle 8 threads concurrently (more high end workload power). Hyperthreading on the other hand is Intel's chip splitting a logical thread in half and creating two virtual ones. This allows the processor to handle more threads at one time (more work being done). The problem with that is you only get half the power in each hyperthread. So Intel can offer 8 threads at a time, but they are 8 crippled threads. As each core still has to compute both hyperthreads. AMD has the upper hand as they offer 8 full logical threads. But again the core performance is the only thing missing to make all that power worth while.

If they can get to nehalem speeds, i think that would make them better bang for buck then intel if they mainten they price/core. What amd needs is hyperthreading. Yes, cmt is better, why not give us both? Widen the module a bit, run four threads on one module.

The stock clocks for these two chips are 3.2 and 3.5. As far as I know this is right around the exact same clocks as the Ivy chips. Both have turbo with the PD chips having slightly higher but not enough that IPC isn't still hugely important.

The 8300 and 8320 are 3.2 and 3.5, but the 8350 is 4.0
post #57 of 92
Making sure I get the 8350 this time for the added clock speed, I made the mistake of getting the 8120 instead of the 8150, because I could just overclock them. So I got an NZXT Havik 140, Crosshair V formula, but then I realised either my chip is a really bad overclocker (the temps to get 4.5 stable were like 70-75'C), or I'm just terrible at overclocking, which could be more likely, as this was my first attempt and I failed miserably and gave up, so I have a heatsink that pushes against my RAM and is louder than my case fans (still no where near as loud as the stock heatsink), but it's at stock mad.gif

I don't think its the chip, sounds like you just need a better cooler, a corsair h80 or h100 perhaps.

Yeah, I agree. Back when I had a FX-8120, it needed a whole 1.44V just to do 4.4 GHz. Anything more would have required either a custom WC setup or a prepackaged liquid cooling solution, such was the quantity of heat emitted. To make matters worse, at those speeds it was pretty much identical in performance to my X6 @ 4GHz. Progress...rolleyes.gif
