In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 230 v2 are significantly better than the Nvidia GeForce GT 620.

The GeForce GT 620 has a 200 MHz higher core clock speed than the GT 230, but the GT 230 has 32 more Texture Mapping Units than the GeForce GT 620. As a result, the GT 230 exhibits a 12.8 GTexel/s better Texture Fill Rate than the GeForce GT 620. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 620 has a 200 MHz higher core clock speed than the GT 230, but the GT 230 has 8 more Render Output Units than the GeForce GT 620. As a result, the GT 230 exhibits a 3.2 GPixel/s better Pixel Fill Rate than the GeForce GT 620. 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 GT 230, 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 GT 230.

The GT 230 has 512 MB more video memory than the GeForce GT 620, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 230 also has superior memory performance overall.

The GT 230 has 9.6 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the GT 230 is marginally better than the GeForce GT 620.

Both the GeForce GT 230 v2 and the GeForce GT 620 have 96 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce GT 620 is 134 and by the GT 230 is 134. Knowing that the shader performance of the GeForce GT 620 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 620 transistor size technology is 15 nm (nanometers) smaller than the GT 230. This means that the GeForce GT 620 is expected to run slightly cooler and achieve higher clock frequencies than the GT 230.

The GeForce GT 230 v2 requires 75 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the GT 230 and a PSU with at least 300 Watts for the GeForce GT 620. The GT 230 requires 26 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the GT 230 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 620.

GPU Mini Review

Mini ReviewOverview
GeForce GT 230 v2 is a Middle-Class Graphics Card based on the First Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G92b which has 6 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 48 TMUs and 12 ROPs. The Central Unit is clocked at 500MHz.

Memory
The GPU accesses a 1.5GB frame buffer of DDR2, through a 192-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 10.0 Support (10.0 Hardware Default) and support for NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

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

Power Consumption
With a rated board TDP of 75W, it relies entirely on the PCI Slot for Power meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance on level with a Radeon HD 5570, meaning it is slightly faster than the more recent Fermi GeForce GT 430.
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.
