In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 780 Gainward Phantom GLH Edition are significantly better than the Nvidia GeForce GTX 295 Asus Mars ROG 4GB Edition.

The GTX 780 has a 332 MHz higher core clock speed and 32 more Texture Mapping Units than the GTX 295. This results in the GTX 780 providing 84.5 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 780 has a 332 MHz higher core clock speed but 8 fewer Render Output Units than the GTX 295. The lower ROP count doesn't matter, though, as altogether the GTX 780 manages to provide 10.7 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 780 was released over three years more recently than the GTX 295, and so the GTX 780 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 295 when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 295 has 1024 MB more video memory than the GTX 780, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 780 has superior memory performance.

The GTX 780 has 6.8 GB/sec greater memory bandwidth than the GTX 295, which means that the memory performance of the GTX 780 is marginally better than the GTX 295.

The GeForce GTX 295 Asus Mars ROG 4GB Edition has 480 Shader Processing Units and the GeForce GTX 780 Gainward Phantom GLH Edition has 2304. However, the actual shader performance of the GTX 295 is 715 and the actual shader performance of the GTX 780 is 2380. The GTX 780 having 1665 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 780 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 295.

The GTX 780 transistor size technology is 27 nm (nanometers) smaller than the GTX 295. This means that the GTX 780 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 295.

The GeForce GTX 295 Asus Mars ROG 4GB Edition requires 500 Watts to run but there is no entry for the GeForce GTX 780 Gainward Phantom GLH Edition. We would recommend a PSU with at least 750 Watts for the GTX 295 and a PSU with at least 600 Watts for the GTX 780. The GTX 295 has been recommended a PSU with 150 Watts more than the GTX 780. The difference is significant enough that the GTX 295 may have an adverse affect on your yearly electricity bills in comparison to the GTX 780.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 295 Asus Mars ROG 4GB Edition is a special edition of NVIDIA's Dual Graphics GeForce GTX 295, created by Asus.

Overclock: Central Unit
The Central Unit now runs at 648MHz, instead 576MHz.

Overclock: Memory Clock
The Operating Memory Clock runs at 1100MHz while the Frame Buffer is now of 4GB. This is a gimmick and in no way benefits the GPU. Furthermore, the GPU now accesses a 1024-bit bus width.

Cooling Solution
The Cooling System remains the same.

Performance
Benchmarks indicate a 20% performance boost over the reference GeForce GTX 295.
GeForce GTX 780 Gainward Phantom GLH Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 980MHz while its boost clock is now of 1033MHz. The memory clock was also increased to 1550MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card.
