In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 720 are significantly better than the Nvidia GeForce GT 620.

The GeForce GT 720 has a 97 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 620. This results in the GeForce GT 720 providing 1.6 GTexel/s better texturing performance. 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 720 has a 97 MHz higher core clock speed and 4 more Render Output Units than the GeForce GT 620. This results in the GeForce GT 720 providing 3.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 720 was released over a year more recently than the GeForce GT 620, and so the GeForce GT 720 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 620.

The GeForce GT 720 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 memory bandwidth of the GeForce GT 720 and the GeForce GT 620 are the same, which means the GeForce GT 720 and the GeForce GT 620 have equal limitations when it comes to graphical data transfer.

The GeForce GT 720 has 192 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the GeForce GT 720 is 153 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 720 having 19 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 720 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 620.

The GeForce GT 720 transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 620. This means that the GeForce GT 720 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 620.

The GeForce GT 720 requires 19 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 720 and a PSU with at least 300 Watts for the GeForce GT 620. The GeForce GT 620 requires 30 Watts more than the GeForce GT 720 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 GeForce GT 720.

GPU Mini Review

Mini ReviewOverview
GeForce GT 720 is a Middle-Class Graphics Card based on the Second Revision of the Kepler Architecture.

Architecture
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.

GPU
It equips a GPU Codenamed GK208 which has 1 Stream Multiprocessor activated and thus offers 192 Shader Processing Units, 16 TMUs and 16 ROPs. The Central Unit is clocked at 797MHz.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 12.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 19W, 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 on average with the older GeForce GT 530.

System Suggestions
We recommend a Modest Processor (Pentium G) and 8GB of RAM for a system with GeForce GT 720.
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.
