In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 240 are noticeably better than the AMD Radeon HD 3850 AGP.

The HD 3850 has a 118 MHz higher core clock speed than the GeForce GT 240, but the GeForce GT 240 has 16 more Texture Mapping Units than the HD 3850. As a result, the GeForce GT 240 exhibits a 6.9 GTexel/s better Texture Fill Rate than the HD 3850. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 3850 has a 118 MHz higher core clock speed and 8 more Render Output Units than the GeForce GT 240. This results in the HD 3850 providing 6.3 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 GeForce GT 240 was released over a year more recently than the HD 3850, and so the GeForce GT 240 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 3850.

The GeForce GT 240 has 512 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 240 also has superior memory performance overall.

The GeForce GT 240 has 1.3 GB/sec greater memory bandwidth than the HD 3850, which means that the memory performance of the GeForce GT 240 is marginally better than the HD 3850.

The GeForce GT 240 has 96 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the GeForce GT 240 is 106 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 108 better shader performance is not particularly notable, as altogether the GeForce GT 240 performs better when taking into account other relevant data.

The GeForce GT 240 transistor size technology is 15 nm (nanometers) smaller than the HD 3850. This means that the GeForce GT 240 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The GeForce GT 240 requires 69 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 240 and a PSU with at least 450 Watts for the HD 3850. The HD 3850 requires 6 Watts more than the GeForce GT 240 to run. The difference is not significant enough for the HD 3850 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 240.

GPU Mini Review

Mini ReviewOverview
GeForce GT 240 is a Middle-Class Graphics Card based on the Second Revision of the Tesla Architecture.

Tesla was NVIDIA's First Unified Shader Architecture.

It equips a GPU Codenamed GT215-450-A2 which has 8 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 32 TMUs and 8 ROPs. The Central Unit is clocked at 550MHz.

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 850MHz.

DirectX 10.1 Support (10.0 Hardware Default) and support for NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 69W, it relies entirely on the PCI Slot for Power meaning no extra connectors are required.

Gaming benchmarks put its performance somewhat above a Radeon HD 4670, meaning it is much faster than the more recent Fermi GeForce GT 430.
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.
