In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are marginally better than the AMD Radeon HD 7540D.

The Radeon HD 7540D has a 60 MHz higher core clock speed than the GeForce GT 620, but the GeForce GT 620 has 4 more Texture Mapping Units than the Radeon HD 7540D. As a result, the GeForce GT 620 exhibits a 2.1 GTexel/s better Texture Fill Rate than the Radeon HD 7540D. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 7540D has a 60 MHz higher core clock speed than the GeForce GT 620 and the same number of Render Output Units. This results in the Radeon HD 7540D providing 0.2 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 Radeon HD 7540D was released less than a year after the GeForce GT 620, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 7540D 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 Radeon HD 7540D has 15.5 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the Radeon HD 7540D is slightly better than the GeForce GT 620.

The Radeon HD 7540D has 192 Shader Processing Units and the GeForce GT 620 has 96. However, the actual shader performance of the Radeon HD 7540D is 95 and the actual shader performance of the GeForce GT 620 is 134. The GeForce GT 620 having 39 better shader performance is not particularly notable, as altogether the Radeon HD 7540D performs better when taking into account other relevant data.

The Radeon HD 7540D transistor size technology is 8 nm (nanometers) smaller than the GeForce GT 620. This means that the Radeon HD 7540D is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 620. While they exhibit similar graphical performance, the Radeon HD 7540D should consume less power than the GeForce GT 620.

The Radeon HD 7540D requires 65 Watts to run and the GeForce GT 620 requires 49 Watts. 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 Radeon HD 7540D. The Radeon HD 7540D requires 16 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the Radeon HD 7540D to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 620.

GPU Mini Review

Mini ReviewRadeon HD 7540D is an embedded GPU on the midle-class Trinity CPU A6-5400K.
Since the GPU doesn't have dedicated memory, the bandwidth will depend on the system ram speed which can be up to 1866MHz (the max speed supported by the CPU) meaning the operating memory speed is 933MHz and whether or not it's dual channel, as the bus width can be 64-bit or 128-bit.
Its core-clock is clocked at 760MHz and comes with 192 Shader Processing Units.
Radeon 7560D's performance depends a lot on driver support and varies from game to game in a way games in the same category (demanding, very demanding, etc) can be unplayable at the lowest settings or might run at medium/high settings.
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.
