In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the Nvidia GeForce 8600 GT Inno3D 512MB GDDR2.

The GTX 980 has a 586 MHz higher core clock speed and 240 more Texture Mapping Units than the 8600 GT. This results in the GTX 980 providing 279.7 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 980 has a 586 MHz higher core clock speed and 120 more Render Output Units than the 8600 GT. This results in the GTX 980 providing 139.8 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 GTX 980 was released over three years more recently than the 8600 GT, and so the GTX 980 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GT when running the latest games.

The GTX 980 has 7680 MB more video memory than the 8600 GT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 980 also has superior memory performance overall.

The GTX 980 has 436 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the GTX 980 is massively better than the 8600 GT.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the GeForce 8600 GT Inno3D 512MB GDDR2 has 32. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the 8600 GT is 43. The GTX 980 having 6681 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a massively smoother and more efficient experience when processing graphical data than the 8600 GT.

The GTX 980 transistor size technology is 52 nm (nanometers) smaller than the 8600 GT. This means that the GTX 980 is expected to run massively cooler and achieve higher clock frequencies than the 8600 GT.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the GeForce 8600 GT Inno3D 512MB GDDR2 requires 47 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980. The GTX 980 requires 303 Watts more than the 8600 GT to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the 8600 GT.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 980 4GB SLI is a solution of two GeForce GTX 980 4GB put together using NVIDIA's SLI technology.

The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

It consists of 2 GPUs codenamed GM204-400-A1 which, together, offer 4096 Shader Processing Units, 256 TMUs and 128 ROPs, on a 512-bit memory interface of fast GDDR5. The central unit runs at 1126MHz and goes up to 1216MHz, in Turbo Mode, while the memory clock operates at 1753MHz.

Power Consumption
Power Consumption lies between 300W and 400W.

Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 980 4GB SLI is over 7% faster than AMD's Radeon R9 295X2.

System Suggestions
We recommend a very strong processor (Intel Core i7 Six Core/AMD FX Eight Core) and 16GB of RAM for a system with GeForce GTX 980 4GB SLI.
GeForce 8600 GT Inno3D 512MB GDDR2 is a special edition of the GeForce 8600 GT. See the standard page for more information about it.
There are no new features and since this version is equipped with GDDR2 and the standard version we have added features standard DDR3, the performance is worse than it. Also, GeForce 8600 GT Inno3D 512MB GDDR2 is not powerful enough to use 512MB of video memory due to the small bandwidth, which results from the slow GDDR2.
