A lot like the 33MHz model. The only noticeable difference is the clock frequency and the description on the CPU is in white letters. Normal Am386 CPU's in ceramic packaging use black letters.... > Read more

A fully 32-bit 386DX running at 33MHz. Both CPU as motherboard run at this frequency.

The CPU runs fine and is the second fastest 'real' (no extra cache or multiplier like a few Cyrix or IBM parts) 386. The fastest part is the Am386DX40.... > Read more

See this Am386 33MHz part for benchmarks. More information about the AMD 386 can be found here.... > Read more

The fastest 386 ever made! It runs at a whopping 40MHz which means it also uses a 40MHz bus. This together tremendously increases the speed of the computer. Combine it with a Vesa Local Bus graphics card and I think it can be faster than the budget, but more expensive, 486 systems.

I have a bunch of these DX40's; apparently they are sold in great quantities back then as it's not difficult to get hands on one even today! In 1992 an Am386DX40 was a good choice: fast, reliable and pretty cheap.... > Read more

Practically identical to this DX40.... > Read more

Just like this DX40; the fastest kind of 386 made.

AMD's 386 was a clone of the Intel 386. Back in the days AMD used to manufacture Intel chips (8086 to 80286) but Intel didn't allow AMD to manufacture a 386. The initial contract didn't state that AMD was... > Read more

An AMD Am386 SX33 on a typical 386SX-motherboard. The difference between SX and DX in the 386 range is the width of the bus. 16-bit for SX and 32-bit for DX. The 16-bit wide motherboards were cheaper to manufacture and usually look a lot like 286 motherboards (that are 16-bit, too). Actually the 16-... > Read more

A 386DX40 in QFP package that is soldered directly to the motherboard. It's fitted on an Octek Jaguar V motherboard which is one of the later 386 boards from the era of affordable 386 DX40's. In the day you could buy DX2/66's with far greater performance- but also a high pricetag. The a good 386DX40... > Read more

AMD's version of the 386SX. It's not much different compared to the 386DX from both AMD and Intel. The SX versions are 32 bits internally but have a 16 bit external bus for communication with memory, chipset and such.

I probably mentioned it elsewhere but: don't confuse the SX/DX from a 386 with ... > Read more

Fastest normal/true 386SX around. Despite that a 386SX40 works just fine it's does not perform that fast. 40MHz in 386DX or 486-terms really is a lot faster.

Of course a lot depends on the application you run but a 386DX at just 25MHz can be about just as fast. Not to mention a DX33 or DX40; they... > Read more

A typical 386SX motherboard with a AMD Am386 SX40 fitted. The chip is dated 31 week 1994 so this this was used for a budget system of it's day. I guess the 40MHz clock favored the sales somewhat since a higher clock is often regarded as a faster system. Nevertheless, the 386SX in essence isn't reall... > Read more
