Performance Increase: 486/DX2 66 to 486/DX4 100

Performance Increase: 486/DX2 66 to 486/DX4 100

Post by Chris Peti » Wed, 20 Dec 1995 04:00:00



I'd like to know what kind of a performance increase I can
expect by swapping my 486/DX2 66 for an AMD 486/DX4 100, and by getting a
motherboard (VLB) with 256K cache (my current board has no external
cache).

        Also, how much of an increase would I get over the above by
putting in a 486/DX5 120?  And how much more would it cost me?

1. 486 DX2-66 => DX4-100 in a laptop.

Hi,

I have a somewhat old laptop (Mitac 4022) with an Intel 486 DX2-66
processor. Since the 486 DX4-100s are really cheap now (BTW, there is
something 486-compatible faster than a DX4-100 out there?), I tought
it would be a nice idea to do an CPU upgrade in my notebook, if it is
at all feasible. From what I could understand in the manual, it seems
to be quite possible to do such upgrade.

I've already seen the chip and it seems to be a "normal" Intel DX2-66.

There are switchers to select the CPU from the following types: SX,
DX, DX2, P23S, P4S, and P24S. As you see, there is no DX3 or DX4, but
I think it's no problem since the settings for DX and DX2 are
identical.

There are also switchers for the CPU-frequency, but just two choices
are available here: 25 and 33 MHz. This is ok, because the DX4-100
operates at 33 MHz, right?

There is also a jumper for selecting between a "S-series CPU" and a
"normal CPU".

The manual has nothing about the CPU voltage, but I hope it's already
cared of in the CPU-type settings.

What are my chances of succeeding in such upgrade, in your opinion?

Thank you in advance for your answer.
