In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 Sapphire 2GB DDR3 Edition are massively better than the Nvidia GeForce GT 630.

The GeForce GT 630 has a 10 MHz higher core clock speed than the HD 7750, but the HD 7750 has 16 more Texture Mapping Units than the GeForce GT 630. As a result, the HD 7750 exhibits a 12.6 GTexel/s better Texture Fill Rate than the GeForce GT 630. 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 630 has a 10 MHz higher core clock speed than the HD 7750, but the HD 7750 has 12 more Render Output Units than the GeForce GT 630. As a result, the HD 7750 exhibits a 9.6 GPixel/s better Pixel Fill Rate than the GeForce GT 630. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7750 was released less than a year after the GeForce GT 630, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7750 has 1024 MB more video memory than the GeForce GT 630, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GT 630 has superior memory performance.

The GeForce GT 630 has 3.2 GB/sec greater memory bandwidth than the HD 7750, which means that the memory performance of the GeForce GT 630 is marginally better than the HD 7750.

The GeForce GT 630 has 96 Shader Processing Units and the Radeon HD 7750 Sapphire 2GB DDR3 Edition has 512. However, the actual shader performance of the GeForce GT 630 is 156 and the actual shader performance of the HD 7750 is 348. The HD 7750 having 192 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GT 630.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 630. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 630.

The GeForce GT 630 requires 65 Watts to run but there is no entry for the Radeon HD 7750 Sapphire 2GB DDR3 Edition. We would recommend a PSU with at least 300 Watts for the GeForce GT 630 and a PSU with at least 400 Watts for the HD 7750. The HD 7750 has been recommended a PSU with 100 Watts more than the GeForce GT 630. The difference is significant enough that the HD 7750 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 630.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 is Middle-Class 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 GF108-400-A1 which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 8 TMUs and 2 ROPs. The Central Unit is clocked at 810MHz.

Memory
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.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.

Power Consumption
With a rated board TDP of 65W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
GeForce GT 630 is essentially a fast GeForce GT 530.
Gaming benchmarks put its performance somewhat above the older GeForce GT 530.

System Suggestions
We recommend a Modest Processor (Intel Celeron) and 4GB of RAM for a system with GeForce GT 630.
Radeon HD 7750 Sapphire 2GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
