In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 530 are significantly better than the Nvidia GeForce GT 620.

The GeForce GT 620 and the GeForce GT 530 have both the same core clock speed and the same Texture Fill Rate. 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 and the GeForce GT 530 have both the same core clock speed and the same Pixel Fill Rate. 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 GeForce GT 530, 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 GeForce GT 530.

The GeForce GT 620 and the GeForce GT 530 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GT 530 has 14.4 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the GeForce GT 530 is slightly better than the GeForce GT 620.

Both the GeForce GT 620 and the GeForce GT 530 have 96 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, although the GPUs are very similar in performance, the GeForce GT 530 takes the edge.

The GeForce GT 620 requires 49 Watts to run and the GeForce GT 530 requires 50 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 GeForce GT 530. The GeForce GT 530 requires 1 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the GeForce GT 530 to have a noticeably larger impact on your yearly electricity bills than 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.
