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 PNY PCIe 1GB Edition.

The GTX 550 Ti has a 275 MHz higher core clock speed and 16 more Texture Mapping Units than the 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 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 GT 620 was released over a year more recently than the GTX 550 Ti, and so the 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 GT 620 PNY PCIe 1GB Edition and the GeForce GTX 550 Ti DirectCU TOP Edition 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 89.9 GB/sec greater memory bandwidth than the GT 620, which means that the memory performance of the GTX 550 Ti is much better than the GT 620.

The GeForce GT 620 PNY PCIe 1GB Edition has 96 Shader Processing Units and the GeForce GTX 550 Ti DirectCU TOP Edition has 192. However, the actual shader performance of the GT 620 is 134 and the actual shader performance of the GTX 550 Ti is 374. 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 GT 620.

The GeForce GT 620 PNY PCIe 1GB Edition requires 30 Watts to run but there is no entry for the GeForce GTX 550 Ti DirectCU TOP Edition. We would recommend a PSU with at least 300 Watts for 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.
GeForce 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.
