In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 650 Gigabyte OC 1GB Edition are massively better than the Nvidia GeForce GT 520 v4.

The GTX 650 has a 512 MHz higher core clock speed and 16 more Texture Mapping Units than the GT 520. This results in the GTX 650 providing 25.9 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 GTX 650 has a 512 MHz higher core clock speed and 12 more Render Output Units than the GT 520. This results in the GTX 650 providing 15.4 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 GTX 650 was released less than a year after the GT 520, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GT 520 v4 and the GeForce GTX 650 Gigabyte OC 1GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 650 has 72 GB/sec greater memory bandwidth than the GT 520, which means that the memory performance of the GTX 650 is much better than the GT 520.

The GeForce GT 520 v4 has 96 Shader Processing Units and the GeForce GTX 650 Gigabyte OC 1GB Edition has 384. However, the actual shader performance of the GT 520 is 115 and the actual shader performance of the GTX 650 is 426. The GTX 650 having 311 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 650 delivers a massively smoother and more efficient experience when processing graphical data than the GT 520.

The GTX 650 transistor size technology is 12 nm (nanometers) smaller than the GT 520. This means that the GTX 650 is expected to run slightly cooler and achieve higher clock frequencies than the GT 520.

The GeForce GT 520 v4 requires 29 Watts to run but there is no entry for the GeForce GTX 650 Gigabyte OC 1GB Edition. We would recommend a PSU with at least 300 Watts for the GT 520 and a PSU with at least 400 Watts for the GTX 650. The GTX 650 has been recommended a PSU with 100 Watts more than the GT 520. The difference is significant enough that the GTX 650 may have an adverse affect on your yearly electricity bills in comparison to the GT 520.

GPU Mini Review

Mini ReviewOverview
GeForce GT 520 v4 is an OEM only, 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 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 4 ROPs. The Central Unit is clocked at 589MHz.

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.

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 on average with Radeon HD 6450.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 520 v4.
GeForce GTX 650 Gigabyte OC 1GB Edition is a special edition of the fast-middle-class GeForce GTX 650 1GB.
This special edition comes overclocked out of the box to 1110MHz and features a custom-designed 10 cm cooler.
Benchmarks indicate a 4% performance boost when compared to the reference card and so this GPU is suitable for medium to high settings on most demanding games but not with extreme resolutions.
