In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are marginally better than the Intel HD i3 3220.

The HD i3 3220 was released less than a year after the GeForce GT 620, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 620 has 1024 MB video memory, but the HD i3 3220 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i3 3220 has 6 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the HD i3 3220 is 19 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 115 better shader performance is not particularly notable, as altogether the HD i3 3220 performs better when taking into account other relevant data.

The HD i3 3220 requires 8 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the HD i3 3220 and a PSU with at least 300 Watts for the GeForce GT 620. The GeForce GT 620 requires 41 Watts more than the HD i3 3220 to run. The difference is significant enough that the GeForce GT 620 may have a slight adverse affect on your yearly electricity bills in comparison to the HD i3 3220.

GPU Mini Review

Mini ReviewHD i3 3220 is a specific version of the Intel HD 2500 Graphics that comes with the CPU 'Core i3-3220 3.3GHz'.
The new features include DirectX 11 and Tessellation support. Using Tesselation might not be a very good idea since even strong fast-middle-class GPUs struggle with it.
The core-clock is initially set at 650MHz and will go to up to 1150MHz, if necessary.
The max memory supported by the CPU is 1600MHz DDR3, therefore the max memory speed is 800MHz.
Benchmarks are yet to become available and so this GPU's rank is subject to change.
Overview
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.
