No, it has the same core as the Cx486DX4. Similar to Intel's 486 DX4.

I see a 5x86 has 16KB cache?

And the one listed on ebay auction a ST486DX4V10HS also has the V10HS marking as the 5x86 does.

Does this mean a ST 5x86???? cpuworld says that ST486DX4V10HS has only 8KB cache.

If it were a 5x86 core i would have bid more to get it probably.

What is the deal with this?

So does the Intel DX4 and some of the AMD DX4

That doesn't necessarily make it a 5x86 core
