In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 XT are very slightly better than the Nvidia GeForce G 100.

The GeForce G 100 was released over three years more recently than the GeForce 6800 XT, and so the GeForce G 100 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 XT when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce G 100 has 256 MB more video memory than the GeForce 6800 XT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce G 100 also has superior memory performance overall.

The GeForce 6800 XT has 3.2 GB/sec greater memory bandwidth than the GeForce G 100, which means that the memory performance of the GeForce 6800 XT is marginally better than the GeForce G 100.

The GeForce G 100 has 8 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the GeForce G 100 is 10 and the actual shader performance of the GeForce 6800 XT is 4. The GeForce G 100 having 6 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce G 100 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The GeForce G 100 requires 35 Watts to run but there is no entry for the GeForce 6800 XT. We would recommend a PSU with at least 300 Watts for the GeForce G 100.

GPU Mini Review

Mini ReviewOverview
GeForce G 100 is an OEM only, Entry-Level Graphics Card based on the Tesla Architecture.

Tesla was NVIDIA's First Unified Shader Architecture.

It equips a GPU Codenamed G98-700-U2 which has 1 Stream Multiprocessor activated and thus offers 8 Shader Processing Units, 4 TMUs and 4 ROPs. The Central Unit is clocked at 567MHz.

The GPU accesses a 512MB frame buffer of DDR2, through a 64-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 500MHz.

DirectX 10.1 Support (10.0 Hardware Default) and support for NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 35W, it relies entirely on the PCI Slot for Power meaning no extra connectors are required.

Gaming benchmarks put its performance considerably below a Radeon HD 4550, meaning even the older GeForce 9400 GT is much faster.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
