In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 520 are very slightly better than the AMD Radeon HD 6450 v3 MSI Low Profile 2GB Edition.

The GeForce GT 520 has a 185 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 6450. This results in the GeForce GT 520 providing 1.5 GTexel/s better texturing performance. 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 520 has a 185 MHz higher core clock speed than the HD 6450 and the same number of Render Output Units. This results in the GeForce GT 520 providing 0.7 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 6450 was released less than a year after the GeForce GT 520, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 6450 has 1024 MB more video memory than the GeForce GT 520, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GT 520 has superior memory performance.

The GeForce GT 520 has 3.7 GB/sec greater memory bandwidth than the HD 6450, which means that the memory performance of the GeForce GT 520 is marginally better than the HD 6450.

The GeForce GT 520 has 48 Shader Processing Units and the Radeon HD 6450 v3 MSI Low Profile 2GB Edition has 160. However, the actual shader performance of the GeForce GT 520 is 78 and the actual shader performance of the HD 6450 is 50. The GeForce GT 520 having 28 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 520 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 6450.

The GeForce GT 520 requires 29 Watts to run and the Radeon HD 6450 v3 MSI Low Profile 2GB Edition requires 18 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 520 and a PSU with at least 400 Watts for the HD 6450. The GeForce GT 520 requires 11 Watts more than the HD 6450 to run. The difference is not significant enough for the GeForce GT 520 to have a noticeably larger impact on your yearly electricity bills than the HD 6450.

GPU Mini Review

Mini ReviewOverview
GeForce GT 520 is an Entry-Level Graphics Card based on the first revision of the Fermi 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.

It equips a GPU codenamed GF119-300-A1 which has 1 Stream Multiprocessors activated and thus offers 48 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit is clocked at 810MHz.

The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

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 29W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Gaming benchmarks put its performance considerably above Radeon HD 5450.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 520.
Radeon HD 6450 v3 MSI Low Profile 2GB Edition is a special edition of AMD's Entry-Level Radeon HD 6450 v3, created by MSI.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Without Overclocking Out of The Box, Radeon HD 6450 v3 MSI Low Profile 2GB Edition is as fast as the reference Radeon HD 6450 v3.
