Gaming Performance Comparison

Recommended System Requirements
Game GeForce GT 620 GeForce GTX 280

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 280 are massively better than the Nvidia GeForce GT 620.

The GeForce GT 620 has a 98 MHz higher core clock speed than the GeForce GTX 280, but the GeForce GTX 280 has 64 more Texture Mapping Units than the GeForce GT 620. As a result, the GeForce GTX 280 exhibits a 37 GTexel/s better Texture Fill Rate than the GeForce GT 620. 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 98 MHz higher core clock speed than the GeForce GTX 280, but the GeForce GTX 280 has 28 more Render Output Units than the GeForce GT 620. As a result, the GeForce GTX 280 exhibits a 16.5 GPixel/s better Pixel Fill Rate than the GeForce GT 620. 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 a year more recently than the GeForce GTX 280, and so the GeForce GT 620 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GTX 280.

The GeForce GT 620 and the GeForce GTX 280 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GTX 280 has 127.3 GB/sec greater memory bandwidth than the GeForce GT 620, which means that the memory performance of the GeForce GTX 280 is massively better than the GeForce GT 620.

The GeForce GT 620 has 96 Shader Processing Units and the GeForce GTX 280 has 240. However, the actual shader performance of the GeForce GT 620 is 134 and the actual shader performance of the GeForce GTX 280 is 332. The GeForce GTX 280 having 198 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 280 delivers a massively smoother and more efficient experience when processing graphical data than the GeForce GT 620.

The GeForce GT 620 transistor size technology is 25 nm (nanometers) smaller than the GeForce GTX 280. This means that the GeForce GT 620 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GTX 280.

The GeForce GT 620 requires 49 Watts to run and the GeForce GTX 280 requires 236 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 620 and a PSU with at least 550 Watts for the GeForce GTX 280. The GeForce GTX 280 requires 187 Watts more than the GeForce GT 620 to run. The difference is significant enough that the GeForce GTX 280 may have an adverse affect on your yearly electricity bills in comparison to 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.
Overview
GeForce GTX 280 is a High-End Graphics Card based on the Second Revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G200-302-A2 which has 10 Stream Multiprocessors activated and thus offers 240 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit is clocked at 602MHz.

Memory
The GPU accesses a 1GB frame buffer of GDDR3, through a 512-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1107MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 236W, it requires at least a 550W PSU and it requires at least two 6-pin available connectors.

Performance
Gaming benchmarks put its performance on average with the lower positioned GeForce GTX 275.
It is therefore even faster than the Fermi based GeForce GTX 460 768MB.
