Leadtek WinFast PX9800 GTX+
Leadtek WinFast PX9800 GTX+ is the most regular GeForce 9800GTX+ video card manufactured following the reference design.
WinFast PX9800 GTX+ is shipped in an orange box of pearl glitter, which is customary for Leadtek. Its appearance has not undergone substantial changes as compared to previous models of video cards by this company.
The package bundle of Leadtek WinFast PX9800 GTX+ includes the following items:
- two power supply adapters for PCI-Express video cards;
- s-video > s-video splitter + component out adapter;
- an S/P-DIF cable for sound transfer via the HDMI port of the video card;
- DVI -> HDMI adapter;
- DVI -> D-Sub adapter;
- the game Neverwinter Nights 2;
- drivers CD;
- User's manual;
Externally, Leadtek WinFast PX9800 GTX+ makes no difference from the old GeForce 9800GTX.
The major distinction of GeForce 9800GTX+ from GeForce 9800GTX is in the renovated GPU G92 which is now manufactured following the 55 nm process technology. Due to the finer process, NVIDIA has succeeded in raising the clock speeds of GeForce 9800GTX+ video cards. Note that ECS HYDRA GeForce 9800GTX+ comes bundled with absolutely the same video cards with the only difference that instead of the air cooling system it uses a fluid-powered cooling system.
G92 chips made following the 55-nm process are of revision B1. The architecture of new G92 chips makes no difference from that of the older G92 chips made following the 65-nm technology.
The memory chips installed on Leadtek WinFast PX9800 GTX+ are made by Hynix and offer 0.8 ns access time, which is equivalent to the effective clock speed 2400 MHz.
The cooling system in GeForce 9800GTX+ also makes no difference from that used in GeForce 9800GTX video cards.
Tests of Leadtek WinFast PX9800 GTX+ for heating and overclocking
We note that the system of air cooling for Leadtek WinFast PX9800 GTX+ proved to be quieter than the system of fluid-powered cooling on ECS HYDRA GeForce 9800GTX+ video cards. Of course, that does not apply to all the other GeForce 9800GTX+ video cards made following the reference design. But we should not forget that ECS HYDRA GeForce 9800GTX+ comes bundled with two video cards. But as the experience suggests, two GeForce 9800GTX+ video cards with an air-cooling system which are manufactured following the reference design will be quieter than the ECS HYDRA GeForce 9800GTX+ kit. Now let's see how hotter the Leadtek WinFast PX9800 GTX+ will prove as compared to the counterparts from the ECS HYDRA GeForce 9800GTX+ kit.
 Leadtek WinFast PX9800 GTX+ was heated by 10 degrees higher than the video card from the ECS HYDRA GeForce 9800GTX+ kit. We'll be able making the final conclusion regarding the fluid-powered cooling only after comparing the overclocking results for ECS HYDRA GeForce 9800GTX+ versus the overclocking results for Leadtek WinFast PX9800 GTX+. Therefore, Leadtek WinFast PX9800 GTX+ was overclocked to 848/1998 MHz for the GPU. Its video memory like that for ECS HYDRA GeForce 9800GTX+ wouldn't overclock, so we had to leave it at 2203 "effective" MHz. In the end, the shader domain of ECS HYDRA GeForce 9800GTX+ video cards was overclocked to a point merely 50 MHz higher than that for Leadtek WinFast PX9800 GTX+.
As it was in the previous case, the heating of the video cards was done with FUR Renderer Benchmark 1.4.0 in the mode of testing for stability at 1920x1200 and 8X FSAA enabled.
