4400/4600/4800+ x2 on a 8800, bottleneck?

[bobert50]

Saw this question on another post re would an E6400 bottleneck a 8800 series or not. I'm just curious if an x2 4400/4600/4800+ would as i currently have a 3700+ san diego but my motherboard can take any of them. I was thinking of upgrading to a duos core but this might be a cheaper option for me unless duos cores were considerably faster in games. Anyone know if one of the athy 64 x2's would bottleneck my pc badly if i had an 8800gts/8800gtx ?

Thanks!

Thanks!

Even the X6800 is a bottleneck.

Depends what res you play at!

In most games the following rings true:

Lower res (1280x1024) = cpu limitation. Conroes perform very well here due to their excellent number crunching abilities! I personally notice quite an increase in frame rate (fraps) clocking from 1.8ghz to 2.8ghz on my Opty 165.

Higher res (1600x1200+) = gpu limitation. At this point your 8800 takes over and the cpu speck doesn't matter too much!

Thanks for the replies

Seems i wouldn't be saving enormous amounts so i feel a duos core move coming soon! while selling my old bits!

Just make sure that the speed of each core in you dual core CPU is faster than your single core, or you'll be disappointed.

If you have a 2.4 GHz single core and go to a dual 2.2 GHz CPU, you'll get less performance in most games. There aren't many that are properly multi-threaded yet, despite the hype.

^ the above post isnt completely true. Only for AMD chips Just incase anyones reading this who is wondering about Intels aswell.

Core2Duo cores dont need to run at as high speeds as current AMD counterparts, better architecture etc
Not sure how they all compare, but to be honest, its not like you're only ever going to be running one process is it.

 

[Cartho]

exactly.
A 3.6 Ghz Pentium 4 would be trashed in games in terms of performance by a 1.8 Ghz E6300.....

 

[peetee]

and who even has a core2duo running @ 1.8?

Thanks for the input new pc parts ordered and should all be with me friday.

E6600 (hoping to clock it to 3.0/3.2 or so)
Abit Fatal1ty FP-IN9 SLI NF650i SLi
2gb geil 6400 ram
8800gtx 320mb

already found a buyer for old stuff and the difference is going to set me back about £350-£400 for a whole new pc so overall very chuffed

 

[peetee]

cool! Mine only wound up setting me back about £400-500 but i got a cheaper CPU, cheaper gfx although Id got new HD case PSU etc.

You should easy hit 3ghz..
I got my 4300 to it, and its a lower stock FSB but same multi 3ghz is generally somewhat easy even with the cheapest c2ds

 

[bobert50]

yea can't wait to get the parts and try oc'ing it! i know i could have got better value especially with the E6300/E6400 but decided on the E6600 eventually as its not a terrible price!.

Besides i seem to have some curse in the past with overclocking! so even if my curses continues i'll still have a healthy 2.4ghz to keep games flying

I've never really understood this question... At the moment the cards are bottlenecked right?
However, when all the DX10 trickery comes into play (some random time in the future) Is it not designed to take a lot of the workload off of the CPU? Meaning that the cards would no longer be bottlenecked?

It is actually when you compare like for like

That is, for single threaded apps:

A single core 2.2GHz A64 will be faster than a dual core 2.0GHz A64

A single core 2GHz Core Solo will be faster than a dual core 1.8GHz Core Duo

A single core 3GHz Pentium 4 will be faster than a dual core 2.8GHz Pentium D


Clock for clock an Intel Core 2 is faster than an AMD A64 but the single core versus dual core argument is the same

Good review here of the performance with the Athlon 64's and the 8800's.
