In terms of overall gaming performance, the graphical capabilities of the AMD FireGL V7700 are significantly better than the Nvidia GeForce GT 620.

The GeForce GT 620 was released over three years more recently than the FireGL V7700, and so the GeForce GT 620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the FireGL V7700 when running the latest games.

The GeForce GT 620 has 512 MB more video memory than the FireGL V7700, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the FireGL V7700 has superior memory performance.

The FireGL V7700 has 57.6 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the FireGL V7700 is much better than the GeForce GT 620.

The GeForce GT 620 has 96 Shader Processing Units and the FireGL V7700 has 320. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the FireGL V7700 is 161. The FireGL V7700 having 27 better shader performance and an altogether better performance when taking into account other relevant data means that the FireGL V7700 delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 620.

The GeForce GT 620 requires 49 Watts to run but there is no entry for the FireGL V7700. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 350 Watts for the FireGL V7700. The FireGL V7700 has been recommended a PSU with 50 Watts more than the GeForce GT 620. The difference is significant enough that the FireGL V7700 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.
The ATI FireGL range of video cards, renamed to FirePro 3D in late 2008, is the series specifically for CAD (Computer Aided Design) and DCC (Digital Content Creation) software, usually found in workstations. The FireGL line is designed for multimedia content creation programs, such as 3DS Max, and mechanical engineering design software such as Solidworks, whereas Radeon counterparts are suited towards video games. FireGL drivers were built with maximum image quality and pixel precision, with CAD specific functionalities such as the recently introduced AutoDetection Technology to tune the parameters inside the driver to achieve maximum performance for predefined list of software. However, because the drivers are also based on the Catalyst drivers made for the Radeon line, it makes them suitable for gaming, at the expense of probable compatibility issues with the very latest games due to the age of the drivers, with FireGL cards in theory pushing more data than their Radeon gaming counterparts.
