In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 220 v2 Galaxy 1GB Edition are significantly better than the Nvidia GeForce GT 420.

The GeForce GT 420 has a 75 MHz higher core clock speed than the GT 220, but the GT 220 has 12 more Texture Mapping Units than the GeForce GT 420. As a result, the GT 220 exhibits a 7.2 GTexel/s better Texture Fill Rate than the GeForce GT 420. 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 420 has a 75 MHz higher core clock speed than the GT 220, but the GT 220 has 4 more Render Output Units than the GeForce GT 420. As a result, the GT 220 exhibits a 2.2 GPixel/s better Pixel Fill Rate than the GeForce GT 420. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 420 was released less than a year after the GT 220, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 420 has 1024 MB more video memory than the GT 220, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 420 also has superior memory performance overall.

The GeForce GT 420 has 22.4 GB/sec greater memory bandwidth than the GT 220, which means that the memory performance of the GeForce GT 420 is slightly better than the GT 220.

Both the GeForce GT 220 v2 Galaxy 1GB Edition and the GeForce GT 420 have 48 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce GT 420 is 67 and by the GT 220 is 67. Knowing that the shader performance of the GeForce GT 420 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 220 v2 Galaxy 1GB Edition requires 58 Watts to run and the GeForce GT 420 requires 50 Watts. We would recommend a PSU with at least 300 Watts for the GT 220 and a PSU with at least 300 Watts for the GeForce GT 420. The GT 220 requires 8 Watts more than the GeForce GT 420 to run. The difference is not significant enough for the GT 220 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 420.

GPU Mini Review

Mini ReviewOverview
GeForce GT 220 v2 Galaxy 1GB Edition is a Special Edition of NVIDIA's Entry-Level GeForce GT 220 v2, created by Galaxy.

Overclock: Central Unit
None.

Overclock: Memory Clock
The Operating Memory Clock is now of 400MHz instead of 790MHz because the GPU Acesses a GDDR2 Frame Buffer, instead of GDDR3.

Frame Buffer
Untouched.


Cooling Solution
Untouched.

Performance
Performance is Lower than the Reference GeForce GT 220 v2, especially at Higher Resolutions.
Overview
GeForce GT 420 is an OEM only 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 GF108-200-A1 which has 1 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 4 TMUs and 4 ROPs. The Central Unit is clocked at 700MHz.

Memory
The GPU accesses a 2GB 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 900MHz.

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 50W, 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 around of a Radeon HD 5450.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 430.
