In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 550 Ti DirectCU TOP Edition are massively better than the AMD Radeon HD 6450 Sapphire OC 512MB Edition.

The GTX 550 Ti has a 225 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 6450. This results in the GTX 550 Ti providing 25.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 550 Ti has a 225 MHz higher core clock speed and 20 more Render Output Units than the HD 6450. This results in the GTX 550 Ti providing 20.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 6450 was released less than a year after the GTX 550 Ti, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 550 Ti has 512 MB more video memory than the HD 6450, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 550 Ti also has superior memory performance overall.

The GTX 550 Ti has 72.9 GB/sec greater memory bandwidth than the HD 6450, which means that the memory performance of the GTX 550 Ti is much better than the HD 6450.

The Radeon HD 6450 Sapphire OC 512MB Edition has 160 Shader Processing Units and the GeForce GTX 550 Ti DirectCU TOP Edition has 192. However, the actual shader performance of the HD 6450 is 60 and the actual shader performance of the GTX 550 Ti is 374. The GTX 550 Ti having 314 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 550 Ti delivers a massively smoother and more efficient experience when processing graphical data than the HD 6450.

The Radeon HD 6450 Sapphire OC 512MB Edition requires 18 Watts to run but there is no entry for the GeForce GTX 550 Ti DirectCU TOP Edition. We would recommend a PSU with at least 300 Watts for the HD 6450.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6450 Sapphire OC 512MB Edition is a special edition of AMD's Entry-Level Radeon HD 6450, created by Sapphire.

Overclock: Central Unit
The Central Unit now runs at 750MHz, instead of 625MHz.

Overclock: Memory Clock
The Operating Memory Clock and the Frame Buffer both remain the same.

Cooling Solution
The Cooling System remains the same.

Performance
Benchmarks indicate a 11% performance over the reference Radeon HD 6450.
GeForce GTX 550 Ti DirectCU TOP Edition is a special edition of the GeForce GTX 550 Ti. See the page of the standard version for more information.
The features include better cooling and an increase on the core-clock from 900MHz to 975MHz.
Benchmarks indicate the performance is 4.5% better when compared to the reference card.
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
