Hello,

I was wondering what the impact of the Intel Core Duo/Intel Core 2 Duo in combination with Windows Vista (64 bits!) is on the mp version(s) of Rybka 2. Do you therefore need an Intel Core Duo configuration, at a minimum, to use effectively the mp version of Rybka 2? Of course, I know it al depends on the specific configuration but a 'free' gain of playing strength must be possible with regards to a 'standaard' configuration of Windows XP.

I'm planning to buy a dedicated notebook with a Intel Core Duo/Windows Vista configuration with mainly Rybka running! Don't know whether it's worth the 'trouble'!

Many thanks in advance.

I can give you one general software advise:

Obtaining a 64bit Windows version will give you at least a 1.6 times speed up with Rybka. There are two options for getting a 64bit version. Either buy Windows Pro 64bit now (around 150 American bucks), or buy Vista 64bit version.

This is by far the cheapest way to improve Rybka performance, if you are currently using any 32bit system.

With regards to hardware, there is no golden advise. Currently the Intel Core processors are fastest, by perhaps 30% compared to AMD offerings, very roughly speaking. These things can change later this year when both AMD and Intel will send out new products, but even then, it's very hard to say if it's worth waiting. I think the sweet spot for any hardware purchase mainly depends on what you currently have. If I only had a one processor system now, I would probably go out and buy an Intel Core Duo tomorrow. Now I have an AMD dual core system, and I will probably not upgrade until perhaps the end of this year, and then I will buy a four core system. Buying an Intel Core Duo notebook now in no way sounds like a bad idea to my ears, and it could represent a significant performance increase for you.

Some rough guidelines for Rybka performance:

32bit --> 64 bit  = 60% increase.

One core --> dual core  = 70% increase.

And then the Core processors are faster clock for clock than any older processor as well.

Dear Alkelele,

Most appreciate your comments!

I will consider your recommendations when planning to upgrade.

Actually, we're in a pretty complicated time now in terms of CPU quality.

A few years ago, everything (in the normal price range) was 32-bit, 1 CPU. You could just line up the processors from slowest to fastest and would not be too wrong.

Now, it really depends on what app you want to run. For some apps, a 32-bit 1 CPU system still won't be all that bad. For others (like Rybka), it will be light years behind. So, CPU decisions really depend on what you want to do.

In a few years, I expect that things will return to normal. All software will target 64-bit multi-CPU machines, and we'll again be able to just line up the processors from best to worst again.

Alkele,
Very useful reply. I have an AMD dual-core 4600+ and found I could overclock it only 5% (using BIOS automated overclock).
   What is your suggestion for overclocking?
I am also planning to buy an AMD quad-core later this year with 64-bit Vista.
                              Best, CMA

Well, right now, my suggestion for overclocking is, think twice before you do it! :-)

Many people say that it would be stupid not to save the cash you in some sense do when you make your processor perform better. However, serious overclocks require two (or three-four) things: Good motherboard, good memory, good cooling, and a good power supply. The extra price for these things can easily outweigh almost all the money saved on the processor, as far as I can tell. But that really depends on the processor. If it can be overclocked 50%, maybe it is a good idea, but if you can only overclock 30%, why not just buy a 20% faster processor and save the trouble? The new Intel Core processors are very good overclockers, but I think the current AMD line has reached its limits already (for example, it is very difficult to overclock an AMD dual core above 3GHz, and you can buy 2.6 or so right away).

I think overclocking mainly applies for people who really want the best of the best, and not so much as a way to save cash. High overclocks also require higher voltage, and thus a larger electricity bill.

Another general advice: read up on the subject and plan your purchase. Find out what products people recommend for good overclocking performance. These recommendations change from month to month. There's little point in wanting/trying to overclock a system that simply doesn't have the motherboard or memory for it.

I am sure that M ANSARI will have another opinion here, and I do not disagree, I just think that maybe the benefits of overclocking do not apply to that many people. They applied to me one year ago. This gave me state of the art performance for about half a year, and that was that. I'm not sure I will plan to overclock next time, but let's see what AMD can come up with this summer :-)
