In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6770 Asus DirectCU 1GB Edition are marginally better than the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition.

The GTX 650 has a 260 MHz higher core clock speed but 8 fewer Texture Mapping Units than the HD 6770. The lower TMU count doesn't matter, though, as altogether the GTX 650 manages to provide 1.5 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 650 has a 260 MHz higher core clock speed than the HD 6770 and the same number of Render Output Units. This results in the GTX 650 providing 4.2 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 GTX 650 was released over a year more recently than the HD 6770, and so the GTX 650 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6770.

The Radeon HD 6770 Asus DirectCU 1GB Edition and the GeForce GTX 650 Gigabyte OC 1GB 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 650 has 3.2 GB/sec greater memory bandwidth than the HD 6770, which means that the memory performance of the GTX 650 is marginally better than the HD 6770.

The Radeon HD 6770 Asus DirectCU 1GB Edition has 800 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the HD 6770 is 340 and the actual shader performance of the GTX 650 is 426. The GTX 650 having 86 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6770.

The GTX 650 transistor size technology is 12 nm (nanometers) smaller than the HD 6770. This means that the GTX 650 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6770. While they exhibit similar graphical performance, the GTX 650 should consume less power than the HD 6770.

The Radeon HD 6770 Asus DirectCU 1GB Edition requires 108 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 500 Watts for the HD 6770 and a PSU with at least 400 Watts for the GTX 650. The HD 6770 has been recommended a PSU with 100 Watts more than the GTX 650. The difference is significant enough that the HD 6770 may have an adverse affect on your yearly electricity bills in comparison to the GTX 650.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6770 Asus DirectCU 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 Asus's DirectCU 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 at least one available 6-pin connector.

Release Price
Not available.

Performance
Radeon HD 6770 Asus DirectCU 1GB Edition offers exactly the same performance the reference card does.
GeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
