In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are very slightly better than the AMD Radeon HD 6530D.

The GeForce GT 620 was released less than a year after the Radeon HD 6530D, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 620 has 512 MB more video memory than the Radeon HD 6530D, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the Radeon HD 6530D has superior memory performance.

The Radeon HD 6530D has 15.5 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the Radeon HD 6530D is slightly better than the GeForce GT 620.

The GeForce GT 620 has 96 Shader Processing Units and the Radeon HD 6530D has 320. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the Radeon HD 6530D is 92. The GeForce GT 620 having 42 better shader performance is not particularly notable, as altogether the Radeon HD 6530D performs better when taking into account other relevant data.

The GeForce GT 620 requires 49 Watts to run and the Radeon HD 6530D requires 64 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620. The Radeon HD 6530D requires 15 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the Radeon HD 6530D to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 620.

GPU Mini Review

Mini ReviewOverview
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.
Radeon HD 6530D is an integrated GPU in one of AMD's processors. It's part of the high-end class GPUS of this Series. It supports DirectX 11 and uses system memory and it only supports DDR3-1866 memory type.
The performance, is obviously, limited but demanding games should still be playable from low to medium settings (depending on the resolution + DirectX version used), while very demanding games might not run at all or might require very reduced settings. All in all, even though it supports DirectX 11, most likely games that use it are unplayable to the lowest settings or only playable on the lowest settings because every game out there using DirectX 11 is either demanding or very demanding.
