In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 630 v2 are noticeably better than the AMD Radeon HD 3800 series.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The GT 630 was released over three years more recently than the HD 3800, and so the GT 630 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 3800 when running the latest games.

The GT 630 has 512 MB more video memory than the HD 3800, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 630 also has superior memory performance overall.

The GT 630 has 51.2 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the GT 630 is much better than the HD 3800.

The GeForce GT 630 v2 has 96 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GT 630 is 156 and the actual shader performance of the HD 3800 is 0. The GT 630 having 156 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 630 delivers a significantly smoother and more efficient experience when processing graphical data than the HD 3800.

The GT 630 transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the GT 630 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The GeForce GT 630 v2 requires 65 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 300 Watts for the GT 630.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 v2 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 fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 800MHz.

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 v2 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 Core i3) and 8GB of RAM for a system with GeForce GT 630 v2.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
