VIA PT Series: VIA PCI Express for Intel

PT880 PRO: The "Step-Up" Chipset
The PT880 PRO is the lowest cost of the new PCI Express chipsets. VIA believes that the PT880 PRO will appeal to many buyers, since it offers upgrade possibilities that just aren't available on other Socket 775 boards.
The most unique feature is the availability of a full AGP 8X slot on a PCI Express motherboard designed for Socket 775. There is also a PCI Express video slot, but VIA tells us that the PCIe slot will be limited to x4 operation. Based on the performance in our past reviews, an x4 PCIe should certainly be fast enough for any current PCIe video cards. Significantly, an AGP and PCIe can both run simultaneously to power up to 4 monitors in a multi-display configuration.

#14,we don't even know if the PT894 Pro will be more expensive than the PT894, or if it's just a name to help motherboard companies promote their DualGFX products. The nVidia nForce4 SLI is $20 more expensive than the Ultra.
As far as "restoring VIA's reputation", they're not going to focus on that when releasing new products. I have worked with their recent chipsets (PT880, PT800, KT880, KT600, K8T800, K8T800Pro) and I don't think there's anything else they could other than continue to bring good chipsets at low prices to make people that had a bad experience with them 5 years ago change their minds.

If the nForce4 Ultra/SLI mod is of any indication, the PT894[Pro] will be a crippleware scam! Unlike NVIDIA, VIA no longer have any marketing lead to afford ripping off motherboard makers. Support for DDR memory isn't going to restore VIA's reputation, especially with the emerging NVIDIA chipset on Intel platform...ChineseDemocracyGNR - Monday, January 31, 2005 - link
Just for the curious, PCPer has pictures of PT880 Pro and PT894 Pro boards. So what? Well, the PT894 Pro is using the VT8251 southbridge. :)http://www.pcper.com/article.php?aid=114&type=...
These two look very much like Jetway boards from the color scheme. ABIT's PT880Pro is also there.

"Amd socket 939 = socket 754 + 184 pin = 938 pin "That's not exactly how it works, there are a number of power and ground pins that are not tied to the CPU at all. In other words, the calculation comes out somewhat close to reality but that is just coincidence. Otherwise, the Socket940 which needs to use 8 extra data lines and additional clock input would have a much higher pin count than just one over 939.

ALL - We apologize for the confusion this morning. The article posted at 6AM when the VIA NDA was 12 Noon EST (9AM PST). As soon as we realized this the article came down and went back up at the correct NDA time.#6 - Corrected

Wow, this will make for a nice upgrade path for people. If they show up on market fast enough, and ample supply they should do well.Jep4444 - Monday, January 31, 2005 - link
Socket 754 and 939 have a few useless pins. I believe 939 has an extra useless pin.I'm not sure if thats how it works though.

The power of the DDR dimm is drained by the amd processor, or by board? If its the board how many pins are needed? Thanks in advance.#avijay thanks but you didnt answer my question:
- Amd socket 939 = socket 754 + 184 pin = 938 pin

#5 skt939 has dual channel memory controller, not single channel like skt754. I think you can add that for the extra pin in the pin count.avijay - Monday, January 31, 2005 - link
As always, a very nice article! Just one thing to point out:(Page 6) table:
VIA PT894 Reference Board Specifications
CPU Interface Socket 939 Athlon 64 ???
shouldn't that be skt 775!
you might like to correct that wesley.
