In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 620 are significantly better than the Intel HD i5 655K.

The GeForce GT 620 was released over a year more recently than the HD i5 655K, 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 HD i5 655K.

The GeForce GT 620 has 1024 MB video memory, but the HD i5 655K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce GT 620 has 96 Shader Processing Units but the HD i5 655K does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD i5 655K requires 73 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 HD i5 655K. The HD i5 655K requires 24 Watts more than the GeForce GT 620 to run. The difference is not significant enough for the HD i5 655K to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 620.

GPU Mini Review

Mini ReviewN/AOverview
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.
