In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the Intel HD Graphics 3000 Desktop.

The Graphics 3000 has a 150 MHz higher core clock speed than the GeForce GT 620, but the GeForce GT 620 has 14 more Texture Mapping Units than the Graphics 3000. As a result, the GeForce GT 620 exhibits a 9.5 GTexel/s better Texture Fill Rate than the Graphics 3000. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Graphics 3000 has a 150 MHz higher core clock speed than the GeForce GT 620, but the GeForce GT 620 has 2 more Render Output Units than the Graphics 3000. As a result, the GeForce GT 620 exhibits a 1.1 GPixel/s better Pixel Fill Rate than the Graphics 3000. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 620 was released over a year more recently than the Graphics 3000, and so the GeForce GT 620 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Graphics 3000.

The GeForce GT 620 has 1024 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 GT 620 has 96 Shader Processing Units and the HD Graphics 3000 Desktop has 12. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the Graphics 3000 is 65. The GeForce GT 620 having 69 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 620 delivers a marginally smoother and more efficient experience when processing graphical data than the Graphics 3000.

The Graphics 3000 transistor size technology is 8 nm (nanometers) smaller than the GeForce GT 620. This means that the Graphics 3000 is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 620.

The GeForce GT 620 requires 49 Watts to run and the HD Graphics 3000 Desktop requires 95 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 300 Watts for the Graphics 3000. The Graphics 3000 requires 46 Watts more than the GeForce GT 620 to run. The difference is significant enough that the Graphics 3000 may have a slight adverse affect on your yearly electricity bills in comparison to the GeForce GT 620.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620 is an Entry-Level Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU codenamed Fermi GF108-100-KB-A1 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 700MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 500MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 49W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance is somewhat better than Radeon HD 7470.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 620.
Overview
Intel HD Graphics 3000 Desktop are Integrated Graphics in some of Intel's Desktop Sandy Bridge Processors.

Architecture
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.

GPU
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.

Memory
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.

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