In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the Nvidia GeForce 8500 GT.

The GeForce GT 620 has a 250 MHz higher core clock speed and 8 more Texture Mapping Units than the GeForce 8500 GT. This results in the GeForce GT 620 providing 7.6 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 620 has a 250 MHz higher core clock speed than the GeForce 8500 GT and the same number of Render Output Units. This results in the GeForce GT 620 providing 1 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 three years more recently than the GeForce 8500 GT, and so the GeForce GT 620 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 8500 GT when running the latest games.

The GeForce GT 620 has 768 MB more video memory than the GeForce 8500 GT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 620 also has superior memory performance overall.

The GeForce GT 620 has 1.6 GB/sec greater memory bandwidth than the GeForce 8500 GT, which means that the memory performance of the GeForce GT 620 is marginally better than the GeForce 8500 GT.

The GeForce GT 620 has 96 Shader Processing Units and the GeForce 8500 GT has 16. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the GeForce 8500 GT is 18. The GeForce GT 620 having 116 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 8500 GT.

The GeForce GT 620 transistor size technology is 40 nm (nanometers) smaller than the GeForce 8500 GT. This means that the GeForce GT 620 is expected to run much cooler and achieve higher clock frequencies than the GeForce 8500 GT.

The GeForce GT 620 requires 49 Watts to run and the GeForce 8500 GT requires 30 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 350 Watts for the GeForce 8500 GT. The GeForce GT 620 requires 19 Watts more than the GeForce 8500 GT 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 8500 GT.

GPU Mini Review

Mini ReviewOverview
GeForce GT 620 is an Entry-Level Graphics Card based on the first revision of the Fermi 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.

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.

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.

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.

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.
GeForce 8500 GT is a middle-class GPU based on the 80nm variant of the first-shader unified architecture.
It's based on the G86 Core and offers 16 Shader Processing Units, 8 TMUs and 4 ROPs, on a 128-bit memory interface of DDR2. The central unit runs at 450MHz and the memory clock operates at 400MHz. It will consume no more than 45 Watt.
This GPU is only suited for a 1024x768 (or less) resolution. Most of today's games will only run at low settings and extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
