In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 PNY Enthusiast 4GB OC Edition are massively better than the AMD Radeon HD 6870 PowerColor 1GB Edition.

The GTX 770 has a 159 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 6870. This results in the GTX 770 providing 85.2 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 770 has a 159 MHz higher core clock speed than the HD 6870 and the same number of Render Output Units. This results in the GTX 770 providing 5.1 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 770 was released over a year more recently than the HD 6870, and so the GTX 770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6870.

The GTX 770 has 3072 MB more video memory than the HD 6870, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 770 also has superior memory performance overall.

The GTX 770 has 90 GB/sec greater memory bandwidth than the HD 6870, which means that the memory performance of the GTX 770 is much better than the HD 6870.

The GeForce GTX 770 PNY Enthusiast 4GB OC Edition has 1536 Shader Processing Units and the Radeon HD 6870 PowerColor 1GB Edition has 1120. However, the actual shader performance of the GTX 770 is 1706 and the actual shader performance of the HD 6870 is 504. The GTX 770 having 1202 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6870.

The GTX 770 transistor size technology is 12 nm (nanometers) smaller than the HD 6870. This means that the GTX 770 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6870.

The GeForce GTX 770 PNY Enthusiast 4GB OC Edition requires 230 Watts to run but there is no entry for the Radeon HD 6870 PowerColor 1GB Edition. We would recommend a PSU with at least 600 Watts for the GTX 770 and a PSU with at least 500 Watts for the HD 6870. The GTX 770 has been recommended a PSU with 100 Watts more than the HD 6870. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the HD 6870.

GPU Mini Review

Mini ReviewGeForce GTX 770 PNY Enthusiast 4GB OC Edition is a special edition of GeForce GTX 770.
This edition comes with a custom dual fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1059MHz while its boost clock is now of 1111MHz and its frame buffer was doubled to 4GB, which will prove useless. The memory clock was left untouched.
Benchmarks indicate a 4% performance boost when compared to the reference card.
Radeon HD 6870 PowerColor 1GB Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
It has no new features and so it can be addressed as a renamed Radeon HD 6870. Therefore its performance is exactly like the standard's.
