In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition are significantly better than the AMD Radeon HD 6450 v2.

The HD 6450 has a 50 MHz higher core clock speed than the GT 730, but the GT 730 has 8 more Texture Mapping Units than the HD 6450. As a result, the GT 730 exhibits a 5.2 GTexel/s better Texture Fill Rate than the HD 6450. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 6450 has a 50 MHz higher core clock speed than the GT 730 and the same number of Render Output Units. This results in the HD 6450 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 GT 730 was released over three years more recently than the HD 6450, and so the GT 730 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 6450 when running the latest games.

The GT 730 has 1536 MB more video memory than the HD 6450, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 730 also has superior memory performance overall.

The memory bandwidth of the Radeon HD 6450 v2 and the GeForce GT 730 v3 Gigabyte 2GB Edition are the same, which means the HD 6450 and the GT 730 have equal limitations when it comes to graphical data transfer.

The Radeon HD 6450 v2 has 160 Shader Processing Units and the GeForce GT 730 v3 Gigabyte 2GB Edition has 96. However, the actual shader performance of the HD 6450 is 60 and the actual shader performance of the GT 730 is 134. The GT 730 having 74 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 730 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6450.

The Radeon HD 6450 v2 requires 18 Watts to run and the GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts. We would recommend a PSU with at least 300 Watts for the HD 6450 and a PSU with at least 300 Watts for the GT 730. The GT 730 requires 31 Watts more than the HD 6450 to run. The difference is significant enough that the GT 730 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6450.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6450 v2 is an entry-level Graphics Card based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU codenamed Caicos XT which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 750MHz.

Memory
The GPU accesses a 512MB frame buffer of fast GDDR5, through a 64-bit memory interface. The memory clock operates at 900MHz. The size of the frame buffer is adequate.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App 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 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Gaming benchmarks put its performance somewhat above of a GeForce GT 520.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with Radeon HD 6450 v2.
GeForce GT 730 v3 Gigabyte 2GB Edition is a special edition of the middle-class GeForce GT 730 v3.

This Edition comes with a special cooling solution which keeps the GPU cooler under load and no overclock out of the box.

Performance-wise, it's as fast as the reference GeForce GT 730 v3.
