NEW K6-2 is S L O W! ! !

[comptech69]

First off, I have loads of computers. If I can get them at the right price, then I keep the coming in. The problem is that I am lazy and don't want to advertise. So I usually sell them at our july garage sale.

I just recently slapped this one together using tigerdirect's parts. This machine is very slow. My PII 400 will burn this computer with lower spes.

Heres the spes:
AMD K6II-450
256MB PC 133 SDRAM
2.5GB Quantum Bigfoot (yuk!!!)
32X CD-ROM
16MB nVidia TnT Vanta LT Video
56k Modem
ETC........

Is it just me, or are the k62 processors slower than the intel PII?

I ran on a K6-2 400 o/c at 500, but i tried to take the cap off anf i broke the CPU in two, but then i bought another K6-2 500 which is still alive and kickin today, with 60+FPS in Unreal Turny ay 800x600x24, all details maxed :cool:

Welcome to Overclockers.com comptech69. Amd K6 processors are kinda slow in comparison to anything Intel had to offer at that time. Things changed for the better when AMD released the Athlon processor which was as fast and sometimes faster than an equivelantly clocked P3. Right now P3s clock for clock are probably a little bit better than the new athlons but the price is quite a bit higher and they are not avalable in as higher clock speeds.

The standard K6-2 has no level 2 cache, it is on the motherboard. That means that the level 2 cache can only run at the motherboards bus speed, in the case of allmost all socket 7 boards this is 100 mhz at best. By moving the level two cache to the processor, as they did with the K6-3 and both of the K6+ CPU's, it can run at the speed of the CPU. This makes a huge difference in speed. Tiger Direct has K6-2+ CPU's for cheap right now. If that systems board can run one, it would be significantly faster.

P3-S (tualatins) are faster than Athlons at Clock-to-clock cuz they have twice the L2 cache (Athlons have 256KB, P3-S have 512KB)

Welcome to The Forums!

I used to have 3 of those things! Loved 'em. Burnt one to a crisp about a year and a half ago, gave a system with one to my bro-in-law 6 months ago, and just burnt the last one up last week:mad: I miss it!

But they are quite a bit slower than the Intel 400mhz. Back then AMD was staying alive with the budget pc market only, and their cpus were quite a bit slower, but cheap.

I'd have to say that nowadays, with newer chips as cheap as they are, it probably isn't worth it to get another one for that system- when you sell it you aren't going to get big money anyway so why put any more than you have to in.

Nah.. K6-2 Blow... Best thing to do is overclock it till it cant go anymore, Also what kind of hard-drive does your Intel II Have... Mmm.........You know, what kinda heatsink do you have.

Thanks guys, everyone around my town tend to like AMD and say that they will cook and intel. Let me tell you that I took there advise and built an AMD and it is slow just like I thought.

Now for the million dollar question, my board has a cpu multiplier of 5.5 and a core voltage of 1.7 ~ 3.52 and a bus speed of 100mhz. The book says it will support up to a k62-400. It still runs good with a k62-450 but not any higher. Windows will not load any higher than 450. Can I buy a K6-3 450 and have it be compatable? Once again the book says k6-233 ~ k62-400.

K6-2's have a built in clock multiplier. This is true from the 400 on. It interprets 2x as 6x. A standard 450 almost certainly won't run this fast. But a K6-2+ will. If your board will run it, one of these CPU's will greatly improve it's speed. Jan Steunebrink maintains a web page that has BIOS files for the boards that can run these CPU's. As I mentioned before, these CPU's use .18 micron architecture, have 128k level 2 cache, and Athlon 3d Now instructions. They were only meant for laptops, but they are the final upgrade for any socket 7 capable of running them. Do a Google search for k6-III+, and his site will come right up. The standard K6-3 had 256k level 2 cache. But it is discontinued, and people want a fortune for them on ebay. And they aren't nearly as overclockable as the K6-+ series of processors.
