Which is better for games ?

1.6Ghz Dual-Core Centrino
Pentium M Centrino 760 2.0Ghz

Thanks...

 

Maybe you should post this in the hardware forum!

BUT, I would say the dual core, if it's C2D it's even better!

 

For games though...

 

I would say use the dual core for games. Multithreaded games are coming out which would take usage of the dual core. If you asked this question last year, I would have said Pentium M all the way.

 

More importantly, which graphics card is paired with each?

With more and more games coming with multi-CPU support, the dual-core is the better choice.

 

The answer is the dual-core CPU, since Intel never made a dual-core Pentium M, that means this is at least a Core Duo by default, and therefore even at the reduced clockspeed of 1.6GHz it is still faster than a Pentium M @ 2GHz, and that's ignoring the 2nd core altogether. Throw a multi-threaded game at that chip and it will run circles around the P-M.

 

I heard a Pentium M 760 is a Pentium 4 at 3.6Ghz. So would'nt a 1.6GHz x 2 = 3.2Ghz...

 

no, sorry speed doesnt add. an 8 core 3 ghz per core isnt 24 ghz!!! its still 3 ghz...

and there is more to speed than mhz. the arcetucture of new processors is much better and higher performing than older ones.

 

Not Necessarily, but dual cores are much more optimized and efficient, and the second core allows two things to run at once at full speed, compared to one on a single core.
Dang nizzy beat me to it.

 

Will a Pentium M 760 run a minimum required CPU 2.6Ghz ?

 

Unless the application in question does a check against raw CPU clock and absolutely demands 2600MHz the answer is yes.

 

thats why vista rating needs to take off to make it easier for min specs.

 

The Core Duo's are essentially just dual core Pentium M's, so they rate favorably against P4's just like the PM's do. So if a PM 2.0GHz = P4 3.6GHz, then a CD 1.6GHz would equal a dual core P4 2.9GHz. And even better if it's a Core 2 Duo.

Yes.

 

The Core Duo (Yonah) is faster than Pentium M (Dothan) at the same clockspeed. A 1.6GHz Core Duo is easily the equal of a 2.0GHz Pentium M in any single-thread workload, and blows it out of the water in multi-threaded workloads.

 

It's slightly faster than two equivalent Pentium M's, but not by a huge amount. The Core Duo's do not use the Core microarchitecture, they use a tweaked Pentium M architecture. For example, in SuperPi (a single threaded benchmark) a T2080 does the 1M in 40secs, while the 740 does the 1M in 43secds.

 

Yonah is the direct predecessor of Conroe. It's as close to being a member of the Core family as is possible without actually being so.

As for P-M vs. Core in SuperPi - SPi is almost purely bound by memory performance, both bandwidth and latency. Laptops traditionally have far less bandwidth and much higher latency than their desktop counterparts. Thus its relevancy in this context is non-existent.

 

SuperPi is the quintessential single threaded CPU benchmark, and anyway, both those scores are from laptops (obviously) so your mention of desktop counterparts is meaningless. Also look at Pifast, where it's 67secs versus 64secs.

And Core Duo's are the direct predecessor to Core in the same way the Pentium M was the direct predecessor to Core, as the Core Duo's are nothing but a tweaked dual core Pentium M.

As for a CD 1.6GHz being equal to a 2.0GHz Dothan in single threaded apps, that's just plain false.

 

Will a Pentium M 760 run a minimum required CPU 2.6Ghz ?

 

My point is that Super Pi's performance depends on memory performance. Since we're discussing laptops with different processors that have similar memory performance, their similar SPi performance is the obvious outcome. Find a true compute-bound benchmark (say 3dmark 06's CPU test) to compare the two and you will see that Yonah is quite superior to Dothan in SSE & FP performance in particular. Integer IPC didn't vastly improve over Dothan until Conroe, thanks to its 4 instruction issue width (among other factors).

Certainly there are notable differences between each core, amd one can trace even Penryn's lineage back to the Pentium Pro, if desired, but that's a rather pointless excercise.

Anandtech disagrees at least for office productivity apps (largely single-threaded) and content creation (also largely single-threaded). No gaming benchmarks there, or anywhere else I could find that compared Core Duo to P-M.

 

First post on this page.

IOW: unless the application is poorly-coded, yes. Buy the Core Duo though. It's by far the more future-proof of the two choices.

 

THX (U got rep)

 

Please quote a source for this, as SuperPi is widely regarded as the best single core CPU benchmark prior to wPrime. Also, if it's memory bound, please explain why a 730 averages 52s, a 740 averages 443, a 750 averages 40s, and a 760 averages 38s, all with the same memory bandwith on the same chipset?
As for 3dmark06, it's far too favorable to multicores to be useful as a singlethreaded benchmark.

Nope, that link agrees with me perfectly, showing Yonah 11% faster than Dothan in a single threaded office suite benchmark (perfectly corresponding to my SuperPi numbers) and 30% faster in a light multitasking benchmark.

 

Go check out xtremesystems.com forums and you'll see for yourself that memory clock and timings make all the difference in the world when it comes to SPi.

Assign affinity using the task manager then. I'd love to test this for you, but I don't own a system with either processor.

No call for that. I wasn't arguing. Dothan is to Yonah as Yonah is to Merom/Conroe.

Well, if anyone out there cared to test game or media performance with laptops, I'd link you to it. AFAICT though, that's usually reserved for $3000+ gaming laptops.

Again, given Yonah's significantly-improved SSE performance over Dothan AKA "Digital Media Enhancements", it's only natural to assume that media & games would be faster than Dothan, even when limited to a single core.

 

Well, if say BF2142 needs 2.6Ghz CPU could my PM 760 run it good ?
Thanks...

 

This question has been answered several times already. Please stop asking it.

The answer is yes, unless the developers of BF2142 are retarded.

 

Finally someone gave me a straight answer.
Thanks...
