In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics 3000 Desktop are significantly better than the Nvidia GeForce 6600 GT 256MB.

The Graphics 3000 was released over three years more recently than the 6600 GT, and so the Graphics 3000 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 6600 GT when running the latest games.

The 6600 GT has 256 MB video memory, but the Graphics 3000 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6600 GT 256MB has 11 Shader Processing Units and the HD Graphics 3000 Desktop has 12. However, the actual shader performance of the 6600 GT is 6 and the actual shader performance of the Graphics 3000 is 65. The Graphics 3000 having 59 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics 3000 delivers a marginally smoother and more efficient experience when processing graphical data than the 6600 GT.

The HD Graphics 3000 Desktop requires 95 Watts to run but there is no entry for the 6600 GT. We would recommend a PSU with at least 300 Watts for the Graphics 3000, but we do not have a recommended PSU wattage for the 6600 GT.

GPU Mini Review

Mini ReviewSupercharge your gaming with the power of an NVIDIA GeForce 6600 GPU. The NVIDIA GeForce 6600 GPUs deliver best-in-class performance and advanced visual effects for next-generation games. The only GPU in its class with support for Microsoft DirectX 9.0 Shader Model 3.0 and with support for PCI Express, the GeForce 6600 delivers ultra-realistic effects, unmatched features, and rock-solid stability so you can play your game the way its meant to be playedOverview
Intel HD Graphics 3000 Desktop are Integrated Graphics in some of Intel's Desktop Sandy Bridge Processors.

The Sandy Bridge GT2 Core includes support for DirectX 10.1 and OpenGL 3.1. Additionally, it also offers better Video Encoding and Decoding Performance, when compared to its Predecessor.

It equips a GPU Codenamed GT2 which offers 12 Shader Processing Units, 2 TMUs and 2 ROPs. The Central Unit Initially Runs at 850MHz and goes up to 1350MHz, in Turbo Mode.

The GPU Shares the System's RAM which varies from System to System. Typically, the GPU reserves 1.7GB. Depending on whether or not the system's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit memory interface. The operating memory clock also depends on which speed the System's RAM is running and is limited by the highest operating speed that the Processor supports. In this case, it is 667MHz.
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.

The Most Powerful Variant Offers Performance similar to a dedicated GeForce GT 610.
