The “xPro” chipsets (TX Pro, VX Pro, HX Pro, BX Pro, etc) are chipsets from companies like SiS, VIA and ALi relabeled by PCChips, i.e., PCChips gets a chipset like SiS 5598 and writes “TX Pro II” on it instead of “SiS 5598”. A relabeled chipset has exactly the same features of the original chipset.
This story goes back to the time of the Intel 430 VX and Intel 430 TX chipsets release, when users looked for motherboards with these chipsets (VX and TX) and found VX Pro and TX Pro on the market. Since the Pentium Pro processor was realeased by the same time, many believed that they were buying a more advanced motherboard, with better chipset than the ones from Intel – since Pentium Pro was more advanced than the Pentium processor.
Besides PCChips, other companies relabeled some chipsets as well. One of them was AMD, who was willing to release a chipset compatible with their K5 and K6 CPUs. They released the AMD-640 chipset, which was in fact a relabeled Apollo VP-2 from VIA. Another company that relabeled some chipsets was Soyo, who released some motherboard with “ETEQ” chipsets, which were relabeled chipsets from VIA. Even ASUS released a relabeled chipset, Super TX (a relabeled SiS 5598), on their SP97-V motherboard.
As the relabeled chipsets “don’t exist” (are an invention from PCChips, Soyo, AMD and some other companies), you need to know which is the real chipset manufacturer and model from your motherboard, in order to install updated drivers, for instance – specially the video drivers on motherboard with on-board video feature, as it happens with SiS 5598 (“TX Pro II”). For the TX Pro II chipset, just go to SiS website and download the SiS 5598 drivers, for example.
We compiled a table containing the name of the relabeled chipset, its real manufacturer and model and which motherboards use the specified chipset.
Keep in mind that many “manufacturers” like Amptron, Eurone and Matsonic, just to name a few, use relabeled PCChips motherboards. Some of these “manufacturers” use a different naming scheme, which we posted on the table (for example, Amptron PM9100 is, in fact, PCChips M571). But the majority follow the PCChips naming scheme. This table is far from being complete and any correction or addition is welcome.

Note: Be careful to not make confusion between TX3 and TX Pro III. TX3 is a motherboard model produced by SMT, which uses Intel’s 430TX chipset. This motherboard does not have any relationship with those chipsets nor with PCChips.
