A64 CPU debate

[Iam8up]

First off I'm confused on this guide...why does it say 3500+ right above the screen capture of CPUZ saying 3800+?

Second I'm looking at a new motherboard (A8V), RAM (PC3200 Corsair), and CPU...looking at these two...
3700+ Clawhammer, 800MHz FSB, Socket 754, 1MB L2 Cache, 2.4 GHz

3500+ Venice, 1GHz FSB, Socket 939, 512KB L2 Cache, 2.2 GHz

Yea they're underclocking it. Err..no, they're changing the multiplier.
CPU's work like this:
amd 64bit mhz and cpu rating [at stock speeds]= 200mhz * multiplier

1.8ghz (3000+) = 200mhz * 9
2.2ghz (3500+) = 200mhz * 11
2.4ghz (3800+) = 200mhz * 12

There are exceptions to the rule...for instance 4000+ and 3800+, they're both 2.4 ghz. The difference is that the 4000+ has a larger cache, so it gets a different "rating (4000+)".

edit: So what they did was change the <i>200mhz * 12</i> to <i>200mhz * 11</i>, since all AMD 64 939 chips are unlocked downward (ie you couldn't put in a 13 instead of a 12).

edit2: To answer your second question, the board is a socket 939 right? So only the 939 64 bit chip will fit in it. By 939 they mean the amount of pins on the bottom of the cpu, so the 754 wouldn't work with the 939.

Intel: [X 3.0x3][P4 3.0x2][P4 2.4x5 down][P4 1.4]

I can change my motherboard if need be...but what's better? The one step up multiplier and doubled L2 cache or the 200 MHz faster FSB?

 

[apesoccer]

I would stay with the socket 939, it's more upgradable then the 754. I don't know if you can later upgrade to the x2 processors or not with that chipset (the nforce 4 ones you can...).

but what's better? The one step up multiplier and doubled L2 cache or the 200 MHz faster FSB?

Just follow the rating system. Keep in mind however, that the extra cache won't affect all programs or games, so it'll end up acting exactly the same as the lower cache at the same speed in certain instances.

OK, thanks a lot. By upgradable what do you mean? The deluxe edition of this A8V motherboard supports FX CPUs...

Not all Via chipset motherboards accept dual core (X2) cpus. Some boards will, while another mfg's board of the same chipset won't.

The fastest socket 754 is and will remain the 3700+. S754 is being moved too the lower-end market with sempron and stuff

Asus P4P800DX, P4C 2.6ghz@3.25ghz, 2X512 OCZ PC4000 3-4-4-8, MSI 6800Ultra stock, 2X30gig Raid0

Yea, what Fishman and Labbby wrote. =D

Just check what they have on the manufacture's website. If they don't have it there, you can usually find an email address for them on the site and ask them directly. However, this doesn't really matter if you plan on going to the next level of mobo's the next time you buy. They say in another year+ amd will be going to ddr2, so you'd need a different board to support that (again, only if you wanted to use the latest and greatest...i've also heard a rumor that some current chips already support ddr2, there just aren't* any boards out there yet that do [for amd, by nforce or via]). Right now latencies are a bit high for ddr2, but they're coming down and combined with the ondie memory controller, i think it'll do really well and latencies will come down to more respectable levels. [assuming we don't just up and switch to xdr lol]. Bleh i've gone well afield of where i wanted to be...ignore this whole paragraph and go with what Fish and Labby wrote =D.

* i make no claims about SiS...they might have something up their sleave in terms of ddr2 and current processors...
