In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the Nvidia GeForce 605 1GB.

The GeForce GT 620 has a 177 MHz higher core clock speed and 8 more Texture Mapping Units than the GeForce 605 1GB. This results in the GeForce GT 620 providing 7 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 620 has a 177 MHz higher core clock speed than the GeForce 605 1GB and the same number of Render Output Units. This results in the GeForce GT 620 providing 0.7 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 less than a year after the GeForce 605 1GB, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce 605 1GB 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 605 1GB and the GeForce GT 620 are the same, which means the GeForce 605 1GB and the GeForce GT 620 have equal limitations when it comes to graphical data transfer.

The GeForce 605 1GB has 48 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the GeForce 605 1GB is 50 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 84 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 620 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 605 1GB.

The GeForce 605 1GB transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 620. This means that the GeForce 605 1GB is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 620.

The GeForce 605 1GB requires 25 Watts to run and the GeForce GT 620 requires 49 Watts. We would recommend a PSU with at least 300 Watts for the GeForce 605 1GB and a PSU with at least 300 Watts for the GeForce GT 620. The GeForce GT 620 requires 24 Watts more than the GeForce 605 1GB 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 605 1GB.

GPU Mini Review

Mini ReviewOverview
GeForce 605 1GB is an OEM only, Entry-Level Graphics Card based on the second 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 GF119-B1 which has 1 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit is clocked at 523MHz.

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 898MHz.

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 25W, 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 Radeon HD 7350.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce 605 1GB.
