In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680 are massively better than the AMD Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition.

The GeForce GTX 680 has a 6 MHz higher core clock speed and 88 more Texture Mapping Units than the HD 4890. This results in the GeForce GTX 680 providing 88.8 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 GeForce GTX 680 has a 6 MHz higher core clock speed and 16 more Render Output Units than the HD 4890. This results in the GeForce GTX 680 providing 16.2 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 GeForce GTX 680 was released over a year more recently than the HD 4890, and so the GeForce GTX 680 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 4890.

The GeForce GTX 680 has 1024 MB more video memory than the HD 4890, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 680 also has superior memory performance overall.

The GeForce GTX 680 has 57.9 GB/sec greater memory bandwidth than the HD 4890, which means that the memory performance of the GeForce GTX 680 is much better than the HD 4890.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition has 800 Shader Processing Units and the GeForce GTX 680 has 1536. However, the actual shader performance of the HD 4890 is 560 and the actual shader performance of the GeForce GTX 680 is 1625. The GeForce GTX 680 having 1065 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 680 delivers a massively smoother and more efficient experience when processing graphical data than the HD 4890.

The GeForce GTX 680 transistor size technology is 27 nm (nanometers) smaller than the HD 4890. This means that the GeForce GTX 680 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4890.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition requires 190 Watts to run and the GeForce GTX 680 requires 195 Watts. We would recommend a PSU with at least 500 Watts for the HD 4890 and a PSU with at least 550 Watts for the GeForce GTX 680. The GeForce GTX 680 requires 5 Watts more than the HD 4890 to run. The difference is not significant enough for the GeForce GTX 680 to have a noticeably larger impact on your yearly electricity bills than the HD 4890.

GPU Mini Review

Mini ReviewOverview
Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition is a special edition of AMD's High-End Radeon HD 4890, created by Sapphire.

Overclock: Central Unit
The Central Unit now runs at 1000MHz, instead of 850MHz.

Overclock: Memory Clock
The Operating Memory Clock now runs at 1050MHz while the Frame Buffer remain the same.

Cooling Solution
The Cooling System has been replaced by Sapphire's Vapor-X Cooling Solution, which has cooling module on the GPU together with a heatsink and profiled fan venting heat out of the case.

Performance
Benchmarks indicate a 11% performance over the reference Radeon HD 4890.
GeForce GTX 680 is a high-end Graphics Card based on the 28nm, Kepler architecture.
The Kepler architecture allows more SPUs but the Fermi SPUs (used on the 400 & 500 Series) are clocked twice as fast as the Kepler architecture. Therefore, don't let the large amount of Pipelines fool you, as the 1536 Pipelines are equivalent to 768 Pipelines, of the Fermi architecture.
GeForce GTX 680 features a 1006Mhz core-clock that can automatically set itself to 1058Mhz using a technology similar to the one used on Intel GPUs. Another huge surprise is the TDP that went from 244 Watts, to just 195 Watts, as two SPUs of the Kepler architecture consume 10% less power. However, the amount was doubled and so the power save is not as high as it could have been.
GeForce GTX 680 was the fastest single GPU of the world until Radeon HD 7970 GHz Edition was released.
All games will run on the maximum settings smoothly.
