In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the Intel HD Xeon E3-1225.

The GeForce GT 620 was released over a year more recently than the HD Xeon E3-1225, 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 HD Xeon E3-1225.

The GeForce GT 620 has 1024 MB video memory, but the HD Xeon E3-1225 does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Xeon E3-1225 has 12 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the HD Xeon E3-1225 is 32 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 102 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 HD Xeon E3-1225.

The GeForce GT 620 requires 49 Watts to run but there is no entry for the HD Xeon E3-1225. We would recommend a PSU with at least 300 Watts for the GeForce GT 620, but we do not have a recommended PSU wattage for the HD Xeon E3-1225.

GPU Mini Review

Mini ReviewHD Xeon E3-1225 is a specific version of the Intel HD P3000 Graphics that comes with the CPU 'Intel Xeon E3-1225'.
Based on the Sandy Bridge architecture, it also features 12 Shader Processing Units, supports openGL up to 3.1, Shader up to 4.0 and DirectX 10.1. Just like other integrated GPUs, it uses system memory and the max memory supported is DDR3-1333, meaning the max memory speed is 667MHz. The CPUs only supports up to dual-channel memory, meaning a 128 bits bus is the largest bus width supported. It comes clocked at 850MHz but the Turbo Boost of the CPU can set it up to 1350MHz.
Benchmarks indicate its performance is on level with an entry-level NVIDIA GeForce GT 520M.
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.
