My Thoughts on FX-8150 vs 2500k vs 2600k

post #1 of 62
Thread Starter 
When it comes to pure gaming performance, I think the 2500k pulls ahead, but not by much in newer DX11 games, but sometimes it can and by a good margin.

When it comes to heavy loads of compression and editing, the FX 8150 shines and finally out does the 2600k, but the 2600k isn't far behind and also does light loads better.

If the FX-8120 (A downclocked 8150 sold for $200, at least this appears to be the case spec wise) performs similar if overclocked, I think it could easily steal the crown of best price/performance CPU, if you do anything besides gaming. However, from the benches I've seen, when it comes to DX11 games, the FX-8150 seems to do a lot better and sometimes the best, but it can also do bad. So I still think it's possible, but for now, it's still the 2500k's crown.

The 2600k, stands to be the CPU where you want all the performance you can get in terms of 3D, compression, encoding, and gaming, without going into the extreme series.

The 2500k is still as of right now, at least until the FX 8120 is reviewed, still stands alone as the king of price/performance.

The FX-8150, holds a very small niche. If $315 is too much for a CPU and $250 is your limit and you do heavy compression and encoding work and not 3D work, then it's the right one for you. The 2500k doesn't keep up in these situations.

Ranks (worst --> best):

Compression and encoding: 2500k, FX 8150, 2600k
For 3D work & gaming: FX 8150, 2500k, 2600k.

Again, if you're in the majority and are looking for a $200 CPU for your build, I would keep an eye on the FX-8120. The 2500k for the most part outperforms the FX-8150 in gaming, but it's yet to be seen how the 8120 fairs. It's definitely the king if it's $200 and you compress and encode, as well as game. From a pure gaming only standpoint, I don't think the 8120 fairs well, but it's not to be pft'd at without considering your work load.

The only reason a Bulldozer based system would perform on par with an i5 or i7 simply has to do with the fact that most games today are GPU bound; I'll quote Tom's: "I don’t like the fact that AMD has to rely on other components bottlenecking performance to achieve parity, but that’s how this works."

Switch to one that's CPU limited, and...

I'd like to see what a few months of software, scheduling and maybe silicon revisions do for performance. Something still doesn't sit right with me. That said the fat lady sang, and it wasn't anything worth getting out of my seat over.

The amount of power that Bulldozer consumes, makes it not even worth it.

You would have to dish out for a way bigger PSU for that CPU and by that time have spent hundreds more and could of bough a superior Intel system.

That's why I said performance and not gaming. After looking at multiple reviews, the 8150 usually does marginally better in compression and encoding work. Also, the FX-8150 seemed to do pretty well in newer DX11 games, compared to older DX11 and DX9/10.

It's really just quick thoughts on it. I think it makes the 2500k's throne a bit wobbly.

I don't think that is really a concern for the most part, at least when it comes to forcing a PSU upgrade. It's just a tad more than the x6 series. This is from a performance POV any how. It is no doubt a good factor to wage in on for some people. If you're not worried about power usage, than it's not that big of a deal, if you are, I think the 2500k gains another advantage.

Yep, using 150 watts less power, running cooler and $90 cheaper... definitely wobbly.

is intel's black buget big enough to pay off all the review sites

edit:and but how could FX-8 possiblly do WORSE in some single core work than any pII, like a pII x4 980 for example (according to spme benches, must get bck to BFBC2)

The FX-8150 is being released at $269.99; I can go pick up an i5-2500k for $100 (or 59%) less.

Does the 8150 offer 59% greater performance?
