NVIDIA GeForce 7800 GS Preview
Published on November 23th, 2005




Introduction

A month ago, we revealed the existence of the GeForce 7800 GS. Today we have a preview of it for our readers. First of all, you may want to print this article. Not because we write so well, but because it's not everyday you hear a story like this one.

GK-TheDeacon is a professional gamer of the first person shooter genre. He spends long hours playing Quake 4 online and participating in various tournaments. He signed up for a FEAR Multi Player match with a prize of a GeForce 7800 GT going to the winner. GK-TheDeacon managed to beat them all and win the contest. That contest organizer is a large website and was working with NVIDIA on this particular promotion. A few days later he received a small mysterious package. Well it was a card in an anti-static bag, with no box or even a CD containing drivers.

He plugged that card in and went to install the drivers but something was strange. The card was not a normal 7800 GT. In reality it's not a 7800 GT at all. It was a 7800 GS engineering sample. I have no idea how the heck he got it. I believe it was PR mistake. Anyway he signed into a few hardware websites in order to find drivers for his card. He sent us an email and asked if we could hook him up with some drivers.

As soon as I saw his E-mail, I contacted him and spoke with him about it. I asked him to install a remote administration tool so I could take a look at the installed card and investigate it. He agreed and provided me access right then. It took me few minutes to believe that this card was not a fake. This is a real 7800 GS.

The GeForce 7800 GS has 16 pixel pipelines and 6 vertex pipes. The core has been clocked to 375MHz and the memory is clocked at 1000MHz. This reference card looks the same as many other NVIDIA reference boards. The GeForce 7800 GS is based on the G70 architecture after all.

To install this card we had to modify ForceWare 81.94 and add support for GeForce 7800 GS. The DeviceID of this card is: "NVIDIA_G70.DEV_0093.1". After making the required edits we proceeded to the driver installation and took this screenshot for you:


After installing the drivers everything worked just fine. As we mentioned in our previous article, this card suppose to sit just below the GeForce 7800 GT in performance and also lower priced. In this mini review you will find out if it does.
