In terms of overall gaming performance, the graphical capabilities of the GT 620 and the GeForce GT 620 are equal.

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

The GeForce GT 620 PNY PCIe 1GB Edition and the GeForce GT 620 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 620 has 5.8 GB/sec greater memory bandwidth than the GT 620, which means that the memory performance of the GeForce GT 620 is marginally better than the GT 620.

Both the GeForce GT 620 PNY PCIe 1GB Edition and the GeForce GT 620 have 96 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, although the GPUs are very similar in performance, the GeForce GT 620 takes the edge.

The GeForce GT 620 PNY PCIe 1GB Edition requires 30 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the GT 620 and a PSU with at least 300 Watts for the GeForce GT 620. The GeForce GT 620 requires 19 Watts more than the GT 620 to run. The difference is not significant enough for the GeForce GT 620 to have a noticeably larger impact on your yearly electricity bills than the GT 620.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620 PNY PCIe 1GB Edition is a special edition of NVIDIA's Entry-Level GeForce GT 620, created by PNY.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 535MHz while the Frame Buffer remains the same: 1GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Performance
Without Overclocking Out of The Box, GeForce GT 620 PNY PCIe 1GB Edition is as fast as the reference GeForce GT 620.
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.
