In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 630 v4 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 1536 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 29 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the GT 630 is slightly better than the HD 3800.

The GeForce GT 630 v4 has 192 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the GT 630 is 168 and the actual shader performance of the HD 3800 is 0. The GT 630 having 168 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 630 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 3800.

The GT 630 transistor size technology is 27 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. While they exhibit similar graphical performance, the GT 630 should consume less power than the HD 3800.

The GeForce GT 630 v4 requires 50 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for the GT 630.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 v4 is a Middle-Class Graphics Card based on the first revision of the Kepler Architecture.

Architecture
The Kepler Architecture was NVIDIA's big step to power efficiency. Each Stream Multiprocessor (SMX) now hosts 192 Shader Processing Units - against the 48 of older Fermi Architecture, and has been redesigned being now clocked at the same speed of the Central Unit. This means they are more energy efficient and will consequently lead to cooler operating temperatures. However, it also means they are weaker. It can be said that one Fermi SMX is as fast as 2 Kepler SMXs.
Additionally, and not available in all GPUs, Kepler also introduced the Boost Clock Feature. The Boost Clock is an even higher Clock Speed activated when in gaming mode and becomes the effective speed of the GPU.

GPU
It equips a GPU Codenamed GK107-301-A2 which has 1 Stream Multiprocessor activated and thus offers 192 Shader Processing Units, 16 TMUs and 16 ROPs. The Central Unit is clocked at 875MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 891MHz.

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

Power Consumption
With a rated board TDP of 50W, it requires at least a 400W 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 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 v4.
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.
