Which OS will run faster? different OS with different CPUs

I still don't know which one to buy, either a Turion X2 TL-56 @ 1.8GHz with Vista x64 or a Core Duo T2450 @ 2.0GHz with Vista x86

From the opening programs response, converting movies to dvd, and faster processing point of view, which would you guys recommend to me? I already taken care of all the 64 bits drivers in case I go that way, so that isn't a problem for me.

Thanks!

 

go with the Turion as it is 64bit... I think they should preform close to the same..

 

id say the core 2 with x86

 

I would vote for the Turion easily. It is a 64-bit processor using a 64-bit OS, which should result in noticeable improvements over the 32-bit processor and OS.

And seeing as how you've already taken care of the drivers, Vista x64 is by far the superior OS anyway. From my experience, its more stable, more secure, and faster than its 32bit counterpart. The only reason not to use Vista x64 is if you are expecting compatibility problems, and since you've already taken care of it, that won't be a problem.

 

u could get one with a core 2 duo.

 

whats x86?? please dont tell me its an 86 bit version of vista!!!

 

No bud, x86 refers to the architecture (the design) standard that the CPU is built on. 64-bit refers to the amount of data in a chunk of information that a CPU can process at one time. Think of it as bandwidth for the CPU.

 

Yeap, so if you have a 64 bit CPU you are better off getting Vista 64bit version too bad some manufacturers like Acer dont provide the 64 bit drivers for their notebook line

 

x86 == 32bit and x64 == 64bit. the 86 is homeage to the 80x86 (80186,80286.....) line of processors in the past.

Performance wise, the speed between both systems will be around the same, no drastic increase/decrease in performance. You'll need to have native 64bit software to realize the full potential of 64bit OS + processor). From a compatibility view, some 32bit software are still not working with 64bit. And lastly, there are variable factors that may make this comparision difficult, like the amount of ram. I'd go for the Core Duo setup.

 

Umm... not quite. x86 is definitely 32bit, but the 64bit is still x86, it's just an extended set of x86 called x86-64. x86 refers to the set of instructions that the CPU will recognize. There are other sets of instructions like MIPS, Alpha, Sparc, etc. 64bit CPU's will run 32bit code at native speed, there is no penalty to running 32bit software on a 64bit CPU. The CPU runs in 32bit mode. Some 32bit software still isn't running under 64bit versions of Windows, but most will. All 32bit software will run with 32bit Windows.

On to performance differences: the core duo will actually probably work better and faster for most things than the Turion. With this generation of CPU's, the Core architecture is faster per cycle, and it's got 200 more cycles per second than the AMD chip. But they'll be comparable chips. The main differences in speed of the machine will be the amount of RAM and the video card. Especially for transcoding, I'd go with whichever one has more memory, and if that's all equal, go with the better video card.

 

64 bit turion all the way

 

I disagree that Core Duo is faster clock for clock than Turion X2, in the SiSoft CPU benchmarks (4) the Turion wins all but 1 and hangs about the same on that (MFLOPS).

 

^check out the wprime dual core benchmarks. even take out the c2ds

 

There is a noticeable difference in X86 programs and activities in general between a 64Bit Vista system and 32Bit Vista system...

I notice and and believe its about 10-15%

 

This provides an overview about x86:

Go with the Turion, at least you'll have the option of using a 64 bit OS if you choose to one day. The Core Duo is probably a slightly better 32 bit performer but you'll never be able to use 64 bit on that system.

 

What about the MACBook Pro Intel Core 2 Duo? Is that capable of 64bit?

 

Yes, all Core 2 Duo's are capable of running in 64bit mode. That's the main reason I waited for the Core 2 Duo on my laptop (but not for Santa Rosa, which didn't get me much that I was interested in)

 

Yes. All C2D are 64bit. Leopard will be 64 bit.

 

Ok, That's what I though. The previous post before mines scared me for a second.
