In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 4GB SLI are massively better than the Intel HD i7 2600S.

The GTX 980 has a 276 MHz higher core clock speed and 255 more Texture Mapping Units than the HD i7 2600S. This results in the GTX 980 providing 287.4 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 276 MHz higher core clock speed and 127 more Render Output Units than the HD i7 2600S. This results in the GTX 980 providing 143.2 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 980 was released over three years more recently than the HD i7 2600S, 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 HD i7 2600S when running the latest games.

The GTX 980 has 8192 MB video memory, but the HD i7 2600S does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce GTX 980 4GB SLI has 4096 Shader Processing Units and the HD i7 2600S has 6. However, the actual shader performance of the GTX 980 is 6724 and the actual shader performance of the HD i7 2600S is 32. The GTX 980 having 6692 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 HD i7 2600S.

The GTX 980 transistor size technology is 4 nm (nanometers) smaller than the HD i7 2600S. This means that the GTX 980 is expected to run very slightly cooler and achieve higher clock frequencies than the HD i7 2600S.

The GeForce GTX 980 4GB SLI requires 350 Watts to run and the HD i7 2600S requires 95 Watts. We would recommend a PSU with at least 750 Watts for the GTX 980 and a PSU with at least 300 Watts for the HD i7 2600S. The GTX 980 requires 255 Watts more than the HD i7 2600S 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 HD i7 2600S.

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.
Intel HD i7 2600S is the specific version of Intel HD Graphics 2000 Desktop that is Integrated in the Core i7-2600S Processor.

The Central Unit Initially Runs at 850MHz and goes up to 1350MHz, in Turbo Mode.

Frame Buffer: Up to 1.7GB.

Memory Channel: 64-bit or 128-bit.

Memory Clock: Up to 667MHz.

Memory Bandwidth: It is then obvious the Memory Bandwidth depends on a lot of factors and thus this Graphics Card performance may vary heavily from system to system.

Gaming Benchmarks Indicate its Performance is Similar to of a Dedicated GeForce 8400 GS.

System Suggestions
We recommend 4GB of RAM for a system with Intel HD i7 2600S.
