In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 630 v3 are marginally better than the AMD Radeon HD 3850 AGP.

The GT 630 has a 234 MHz higher core clock speed and the same number of Texture Mapping Units as the HD 3850. This results in the GT 630 providing 3.7 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 GT 630 has a 234 MHz higher core clock speed than the HD 3850, but the HD 3850 has 8 more Render Output Units than the GT 630. As a result, the HD 3850 exhibits a 3.5 GPixel/s better Pixel Fill Rate than the GT 630. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GT 630 was released over three years more recently than the HD 3850, 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 3850 when running the latest games.

The GT 630 has 1536 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The HD 3850 has 38.7 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the HD 3850 is noticeably better than the GT 630.

The GeForce GT 630 v3 has 384 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the GT 630 is 346 and the actual shader performance of the HD 3850 is 214. The GT 630 having 132 better shader performance is not particularly notable, as altogether the HD 3850 performs better when taking into account other relevant data.

The GT 630 transistor size technology is 27 nm (nanometers) smaller than the HD 3850. This means that the GT 630 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850. While they exhibit similar graphical performance, the GT 630 should consume less power than the HD 3850.

The GeForce GT 630 v3 requires 25 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 300 Watts for the GT 630 and a PSU with at least 450 Watts for the HD 3850. The HD 3850 requires 50 Watts more than the GT 630 to run. The difference is significant enough that the HD 3850 may have a slight adverse affect on your yearly electricity bills in comparison to the GT 630.

GPU Mini Review

Mini ReviewOverview
GeForce GT 630 v3 is Middle-Class Graphics Card based on the second revision of the Kepler Architecture.

Architecture
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.

GPU
It equips a GPU codenamed Kepler GK208-301-A1 which has 2 Stream Multiprocessors activated and thus offers 384 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is clocked at 902MHz.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 900MHz.

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 25W, 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 v3 is the fastest of all GeForce GT 630 variants, at the lowest resolutions. As the resolutions increases, its performance decreases significantly.
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 v3.
Radeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
