Help me translate Intel specs to AMD

[galbicake]

I am looking to buy a new laptop. I have a software that is very specific about what type of minimum CPU is need but it is only in the form of Intel. (i.e. 1.8Ghz)

I know Dell has nothing but Intels but I am looking at other laptops such as Acer & etc.

Does anyone know of a specific site that converts Intel CPU specs to AMD CPU specs?

Either that or if someone could help explain to me how to convert it using a formula or something.

Thanks!

There's no formula that I know of. The way AMD rates their CPU's was by performance. So if they called it an 1800+, that usually meant it was equal to an Intel CPU running at 1.8Ghz.

You also need to match the proper CPU family.

A sempron is in a class similar to a celeron, and and AMD XP is similar to older Intel P4's.

I don't think there is an exact formula per se. I know some AT'ers will know how to figure this fairly well though. I remember there is some "formula" that considers AMD CPU's at a factor of 9, and Intel at 6. So, a 2Ghz AMD chip (2000x9) would be "the same" as a 3Ghz Intel chip (3000x6). This is assuming you are comparing chips from the same generation and family (i.e. don't compare a pentium III to an Athlon64). There is a ton more to this, I'm sure someone else can clarify.

Of course, this is rough at best. Intel CPU's are better at some things, AMD CPU's are better at others, so your specific needs might shake this up quite a bit.

If you're looking at Penitum Mobile cpu's, they basically match up with Athlon 64 desktop cpu clock speeds. And they use less power, resulting in better up-time using the battery. Those are what I recommend, and Dell does use them in their laptops.

So is the assumption that AMD laptop CPU's are different than AMD desktop CPUs?

Yes. And I would recommend the Pentium M for a laptop, it's best laptop cpu on the market. Very fast and very efficient.

Hi, The assumption is that AMD 2400 will process as fast as a P4 2.4 Gig. but at a lower clock speed. Go to a seller sites and look up the AMD you are intrested in. Some sellers show the actual clock speed of the Processor. Hope this was what you refer to. Luck, Jim

they amd laptop mt series use the least power, but are similiar to the skt754 desktops i think iwth a bit more cache.

even though i like amd and would love to support them all the way at this point in time, i still think the centrino setup is superior and also found in many more laptops then the turion setup.

i have a ibm t42 with a 1.5GHz cpu and it did pretty well encoding into x264 compared to my old desktop of a 2.8C @ 3.0GHz, as did my opty144 @ stock speeds. so basically the p-m is equal in most areas to the actual cpu speed of a a64. now that most of the new p-m laptops use the lower V ddr2, you can bet there will be better run times.

for normal office usage, my t42/512/40/wifi does ~4hrs on the smaller ibm battery, and is still ~5#s. not bad imo

Check the the laptop in this thread, pretty nice deal!

The Athlon64 performance ratings are derived from a comparison to the Intel Pentium 4 by a factor of 1.5. Add to the Athlon64 5% for dual channel advantage and then add another 5% if there is 1MB of L2 cache (opposed to 512KB). Example:

A socket 939 4000+ = 2400Hz * 1.5 = 3600
3600 * 1.05 (dual channel) = 3780
3780 * 1.05 (1MB L2 cache) = 3969 which is roughly equivalent to 4000.

That does sound pretty close to accurate.

With laptops its quite interesting when you get to Celeron-M/Pentium-M.

Celeron-M/1MB will generally outperform a Mobile Sempron64 clock for clock. A 1.4Ghz Celeron-M/1MB is slightly better to a 1.6Ghz Mobile Sempron64 2800+.

A Pentium-M/2MB will perform clock to clock with any mobile Turions or Athlon64's.
