Nvidia graphics card with doubled VRAM

Geforce 9800 GTX+ with 1 GB video memory reviewed

Initially Nvidia's Geforce 9800 GTX+ had been available with 512 MiByte VRAM only. But in the meantime several board partners delivered versions with 1,024 MiByte. We take a closer look at the Gigabyte model.

Geforce 9800 GTX+ with 1 GB video memory reviewed: Introduction
The Geforce 9800 GTX+ is Nvidia's fastest middle-class card. The G92b GPU delivers a good arithmetic performance as well as a high fillrate and the GDDR3 memory has a good memory bandwidth. But with only 512 MiByte VRAM the 9800 GTX+ can sometimes run into problems in games with high texture resolution or when dealing with higher FSAA modes.

Nvidia's board partners recognized this and thus offer the Geforce 9800 GTX+ with 1,024 MiByte, too. The biggest difference to the default design is in many cases not just the cooling solution, but also the board layout and the memory. None of the vendors uses the expensive 0.83 nanoseconds GDDR3 on a middle-class card, but 1.0 ns memory only. Thus all 1,024 MiByte models have a memory frequency of 1,000 MHz or less instead of 1,100 MHZ.

The benchmark review with nine popular games like Left 4 Dead, Fallout 3, Mirror's Edge Crysis Warhead or Fear 2: Project Origin reveals if the doubled amount of video memory can deliver a performance benefit which is worth the extra costs.
