In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6450A are significantly better than the Nvidia GeForce 6800 XT.

The Radeon HD 6450A was released over three years more recently than the GeForce 6800 XT, and so the Radeon HD 6450A 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.

The Radeon HD 6450A has 768 MB more video memory than the GeForce 6800 XT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon HD 6450A also has superior memory performance overall.

The GeForce 6800 XT has 2.7 GB/sec greater memory bandwidth than the Radeon HD 6450A, which means that the memory performance of the GeForce 6800 XT is marginally better than the Radeon HD 6450A.

The Radeon HD 6450A has 160 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the Radeon HD 6450A is 50 and the actual shader performance of the GeForce 6800 XT is 4. The Radeon HD 6450A having 46 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 6450A delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The Radeon HD 6450A requires 25 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 Radeon HD 6450A.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6450A is a Mobile Entry-Level Graphics Card, used In All-In-One PCs that is based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU Codenamed Caicos PRO which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 625MHz.

Memory
The GPU accesses a 512MB frame buffer of GDDR3, through a 64-bit memory interface. The memory clock operates at 533MHz. The size of the frame buffer is adequate.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Power Consumption
With a rated board TDP of 25W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon HD 6450A is essentially a mobile version of Radeon HD 6450 v3 and offers exactly the same performance.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon HD 6450A.
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.
