3870 vs. 3870X2 - Page 3

post #21 of 33
So, how do they stack up to the 9x series?
post #22 of 33
the sad thing is there is no amd chip that will not bottle neck sli or 3870 x2. none period

Why would It Bottleneck ? Ive seen the 5000 BE OC Slightly Higher than the 6400 BE

Yea but not everybody has access to an endless supply of LN2

It will bottleneck because AMD processors, even the high end ones, are slow compared to even my e2180 (clock for clock).

@OP, if you don't already have an AMD system then run! Run as far as you can away from the sinking ship that is AMD so you don't regret wasting $200+ when you realize that you need to switch to intel.

So you're suggesting an e2180 (which is, according to you, faster than "high end" AMD CPU's) will "bottleneck" a 3870x2 / 3870 Crossfire. Again,

I can tell you that a 3ghz e8400 does bottleneck that particular setup. Assuming they are within the relative same speed as an e8400 stock, I would have to say I would agree. Not sure if it would even be beneficial for anyone with an AMD processor at this time to go with a CrossfireX setup as even that cpu would bottleneck 2 gpus.

All these broad statements about bottlenecking....

It's not an objective thing, it's relative to game you are playing and the settings. The higher the resolution, and the more eye candy, the less likely the CPU is going to be the limiting factor.

Also, a 3.2GHz Athlon X2 (1 or 2 meg L2) is going to game faster that most Phenoms, even OCed Phenoms.

The Phenom does have twice as many cores, and is a bit faster clock for clock, but they cannot clock as high, and only a handful of games will make sigificant use of more than two threads.

definitely a CPU bottleneck there. I scored near that with a single 3870 :/
