In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition are noticeably better than the AMD Radeon HD 8350 (OEM).

The GT 420 has a 50 MHz higher core clock speed than the HD 8350, but the HD 8350 has 4 more Texture Mapping Units than the GT 420. As a result, the HD 8350 exhibits a 2.4 GTexel/s better Texture Fill Rate than the 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 GT 420 has a 50 MHz higher core clock speed than the HD 8350 and the same number of Render Output Units. This results in the GT 420 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 HD 8350 was released over a year more recently than the GT 420, and so the HD 8350 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GT 420.

The GT 420 has 1536 MB more video memory than the HD 8350, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 420 also has superior memory performance overall.

The GT 420 has 12.8 GB/sec greater memory bandwidth than the HD 8350, which means that the memory performance of the GT 420 is slightly better than the HD 8350.

The GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition has 48 Shader Processing Units and the Radeon HD 8350 (OEM) has 80. However, the actual shader performance of the GT 420 is 67 and the actual shader performance of the HD 8350 is 26. The GT 420 having 41 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 420 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 8350.

The GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition requires 50 Watts to run and the Radeon HD 8350 (OEM) requires 25 Watts. We would recommend a PSU with at least 350 Watts for the GT 420 and a PSU with at least 250 Watts for the HD 8350. The GT 420 requires 25 Watts more than the HD 8350 to run. The difference is not significant enough for the GT 420 to have a noticeably larger impact on your yearly electricity bills than the HD 8350.

Mini ReviewOverview
GeForce GT 420 Gigabyte Rev. 3.0 2GB Edition is a special edition of NVIDIA's Middle-Class GeForce GT 420, created by Gigabyte.

Overclock: Central Unit

Overclock: Memory Clock
The Operating Memory Clock was reduced from 900MHz to 800MHz.

Cooling Solution
GIGABYTE custom-designed 80 mm cooler, with air flow optimized cover and aluminum base. The cooler can dissipate heat effectively from the GPU while keeping the fan at lower speed and noise.

Benchmarks Indicate no Performance Boost over the Reference GeForce GT 420.
Radeon HD 8350 (OEM) is an OEM Only, entry-level Graphics Card based on the first revision of the Terascale Architecture.

Terascale was AMD's first Unified Shader Architecture. In addition to being manufactured with a 40nm Technology, against the 55nm of previous Graphics Cards, it supports DirectX 10 and the Shaders now called Shader Processing Units have been redesigned and do all the Graphical work of Pixel and Vertex Shaders.

It equips a GPU codenamed Cedar PRO which has 1 Compute Units activated and thus offers 80 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 650MHz.

The GPU accesses a 512MB frame buffer of GDDR3, through a 64-bit memory interface. The memory clock operates at 800MHz. The size of the frame buffer is adequate.

DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, Eyefinity, Stream Acceleration, PowerPlay and other technologies.

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

Power Consumption
With a rated board TDP of 18W, it requires at least a 250W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Radeon HD 8350 (OEM) is a Direct Rebrand of Radeon HD 6350 and performs exactly like it.
Gaming benchmarks indicate its performance is extremely limited and even the older GeForce GT 220 is still faster.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon HD 8350 (OEM).
