In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6770 Sapphire 1GB Edition are marginally better than the Nvidia GeForce GTX 550 Ti DirectCU TOP Edition.

The GTX 550 Ti has a 125 MHz higher core clock speed than the HD 6770, but the HD 6770 has 8 more Texture Mapping Units than the GTX 550 Ti. As a result, the HD 6770 exhibits a 2.8 GTexel/s better Texture Fill Rate than the GTX 550 Ti. 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 125 MHz higher core clock speed and 8 more Render Output Units than the HD 6770. This results in the GTX 550 Ti providing 9.8 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 6770 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 Radeon HD 6770 Sapphire 1GB Edition and the GeForce GTX 550 Ti DirectCU TOP Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 550 Ti has 21.7 GB/sec greater memory bandwidth than the HD 6770, which means that the memory performance of the GTX 550 Ti is slightly better than the HD 6770.

The Radeon HD 6770 Sapphire 1GB Edition has 800 Shader Processing Units and the GeForce GTX 550 Ti DirectCU TOP Edition has 192. However, the actual shader performance of the HD 6770 is 340 and the actual shader performance of the GTX 550 Ti is 374. The GTX 550 Ti having 34 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 550 Ti delivers a slightly smoother and more efficient experience when processing graphical data than the HD 6770.

The Radeon HD 6770 Sapphire 1GB Edition requires 108 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 500 Watts for the HD 6770.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6770 Sapphire 1GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6770. It is a reference card as it features a new Cooling Solution but no overclocking out of the box. Read below to know more.

Overclock Out of The Box
The Central Unit remains clocked at 850MHz and the Memory Clock still operates at 1200MHz.

Cooling Solution
The reference AMD Single-Fan Cooling System has been replaced by Sapphire's Large Single Fan Cooling Solution. This means the card runs cooler under load.

Power Consumption
The Rated Board TDP should remain the same: 108W. We recommend a 500W PSU with one available 6-pin connector.

Release Price
Not available.

Performance
Radeon HD 6770 Sapphire 1GB Edition offers exactly the same performance the reference card does.
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.
