In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 Ultra are noticeably better than the AMD Radeon HD 5450 512MB.

The HD 5450 was released over three years more recently than the GeForce 6800 Ultra, and so the HD 5450 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 Ultra when running the latest games.

The HD 5450 has 256 MB more video memory than the GeForce 6800 Ultra, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the GeForce 6800 Ultra has superior memory performance.

The GeForce 6800 Ultra has 28.8 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the HD 5450.

The Radeon HD 5450 512MB has 80 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the HD 5450 is 52 and the actual shader performance of the GeForce 6800 Ultra is 9. The HD 5450 having 43 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The Radeon HD 5450 512MB requires 20 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the HD 5450. The GeForce 6800 Ultra requires 104 Watts more than the HD 5450 to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the HD 5450.

GPU Mini Review

Mini ReviewThe Evergreen series is a family of GPUs developed by AMD graphics products division. The existence was spotted on a presentation slide from AMD Technology Analyst Day July 2007 as 'R8xx'. ATI held a press event in the USS Hornet museum on September 10, 2009 and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants. The first variants of the Radeon HD 5800 series were launched September 23, 2009, with the HD 5700 series launching October 12 and HD 5970 launching on November 18 The HD 5670, was launched on January 14, 2010, and the HD 5500 and 5400 series were launched in February of 2010, completing what has appeared to be most of ATI's Evergreen GPU lineup.
Demand so greatly outweighed supply that more than two months after launch, many online retailers were still having trouble keeping the 5800 and 5900 series in stock.
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.
