In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 550 Ti DirectCU TOP Edition are massively better than the Nvidia GeForce GT 620.

The GTX 550 Ti has a 275 MHz higher core clock speed and 16 more Texture Mapping Units than the GeForce GT 620. This results in the GTX 550 Ti providing 20 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 GTX 550 Ti has a 275 MHz higher core clock speed and 20 more Render Output Units than the GeForce GT 620. This results in the GTX 550 Ti providing 20.6 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 620 was released over a year more recently than the GTX 550 Ti, 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 GTX 550 Ti.

The GeForce GTX 550 Ti DirectCU TOP 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 GTX 550 Ti has 84.1 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the GTX 550 Ti is much better than the GeForce GT 620.

The GeForce GTX 550 Ti DirectCU TOP Edition has 192 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the GTX 550 Ti is 374 and the actual shader performance of the GeForce GT 620 is 134. The GTX 550 Ti having 240 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 550 Ti delivers a massively 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 GTX 550 Ti. We would recommend a PSU with at least 300 Watts for the GeForce GT 620, but we do not have a recommended PSU wattage for the GTX 550 Ti.

GPU Mini Review

Mini ReviewGeForce GTX 550 Ti DirectCU TOP Edition is a special edition of the GeForce GTX 550 Ti. See the page of the standard version for more information.
The features include better cooling and an increase on the core-clock from 900MHz to 975MHz.
Benchmarks indicate the performance is 4.5% better when compared to the reference card.
Some modern demanding games will run at the highest settings using a 1080p resolution but the largest part will have to be played with a 720p resolution to be played optimally.
This Graphics Card needs to be paired with a decent Quad Core CPU.
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.
